GLP-1s Increase GERD Risk Over SGLT2 Inhibitors in T2D

In patients with type 2 diabetes (T2D), the risks for gastroesophageal reflux disease (GERD) and GERD-related complications were greater with GLP-1 receptor agonist (RA) use than with SGLT2 inhibitor use in a cohort study of new users.

Risks for GERD were higher overall for each GLP-1 RA type except lixisenatide, and risks for GERD complications were higher in ever-smokers, patients with obesity, and patients with gastric comorbidities.

“The findings were not entirely surprising,” principal author Laurent Azoulay, PhD, of McGill University and Lady Davis Institute for Medical Research, Jewish General Hospital, Montreal, Quebec, Canada, told GI & Hepatology News. “There is a plausible biological mechanism through which GLP-1 RAs could increase the risk of GERD — namely, by delaying gastric emptying, which can lead to symptoms of reflux. Still, it’s always valuable to see whether the clinical data support what we suspect from a physiological standpoint.”

“As with any medication, it’s about balancing benefits and risks — and being proactive when side effects emerge,” he added.

The study was published online in Annals of Internal Medicine.

 

Duration of Use, Drug Action

Researchers designed an active comparator new-user cohort study emulating a target trial to estimate the effects of GLP-1 RAs compared with SGLT2 inhibitors on the risk for GERD and its complications among patients with T2D.

The study included 24,708 new users of GLP-1 RAs and 89,096 new users of SGLT2 inhibitors. Participants had a mean age of 56 years, and 55% were men. They initiated treatment with the drugs from January 2013 through December 2021, with follow-up through March 2022.

Three-year risk differences (RDs) and risk ratios (RRs) were estimated and weighted using propensity score fine stratification.

Overall, during follow-up, the incidence rate of GERD was 7.9 per 1000 person-years; 138 complications of GERD were observed, with over 90% of them being Barrett’s esophagus.

Over a median follow-up of 3 years, among GLP-1 RA users compared with SGLT2 inhibitor users, the RRs were 1.27 for GERD, with an RD of 0.7 per 100 patients, and 1.55 for complications, with an RD of 0.8 per 1000 patients.

Further analyses found that risks for GERD were higher overall for each GLP-1 RA type except lixisenatide, and risks for GERD complications were higher in ever-smokers, patients with obesity, and those with gastric comorbidities associated with gastric motility. The findings remained robust across sensitivity analyses addressing various types of biases.

The widening incidence curves with duration of use may indicate that mucosal injury and symptom severity correlate with reflux frequency and duration of esophageal acid exposure, the authors suggested.

GERD risk also was higher with long-acting GLP-1 RA use, suggesting that long-acting GLP-1 RAs (liraglutide, exenatide once weekly, dulaglutide, and semaglutide) may have more sustained delaying effects, they noted.

“These potential risks should be weighed against the established clinical benefits of this drug class, particularly in patients at high risk for gastroparesis and GERD,” the authors concluded.

“Given the mechanism through which these drugs may cause GERD, we can reasonably speculate that a similar effect might be observed in individuals without diabetes,” Azoulay added. “That said, a dedicated study would be needed to confirm that.”

 

Close Monitoring Advised

Caroline Collins, MD, assistant professor at Emory University School of Medicine in Atlanta, agreed with the findings and said the association between GLP-1s and GERD is consistent with what she has observed in her practice.

“I routinely counsel patients about the potential for GERD symptoms as well as other side effects before initiating GLP-1 therapy,” she told GI & Hepatology News. “Several patients on GLP-1s have reported new or worsening reflux symptoms after initiating therapy. Sometimes, we can lower the dose, and the GERD resolves. Other times initiating GERD treatment or discontinuing the medication is appropriate.”

“Patients with T2D are already at increased risk for delayed gastric emptying, which in itself is a contributor to GERD,” said Collins, who was not involved in the study. “Therefore, adding a GLP-1 RA, which further slows gastric motility, may compound this risk. I consider this when assessing which patients are the best candidates for these medications and often monitor more closely in patients with long-standing diabetes and other predisposing factors to GERD.”

Barrett’s esophagus and esophageal cancer generally occur over many years, she noted. “A median follow-up of 3 years may be insufficient to fully assess the long-term risks of serious complications.”

Chronic cough, a common but often overlooked manifestation of GERD, was not included in the outcome definitions,” she added. Including chronic cough “may have captured a broader picture of reflux-related symptoms.”

The study was funded by a Foundation Scheme grant from the Canadian Institutes of Health Research. Azoulay holds a Distinguished Research Scholar award from the Fonds de recherche du Quebec – Sante and is the recipient of a William Dawson Scholar award from McGill University.

Medicolegal Concerns in Contemporary Private GI Practice

Article Type
Changed
Wed, 10/01/2025 - 13:37

The need for gastroenterology (GI) services is on the rise in the US, with growing rates of colonoscopy, earlier-onset colon cancer, and inflammatory bowel disease. This increase is taking place in the context of a changing regulatory landscape.

With expanded GI practice opportunities comes the need to raise awareness of medicolegal issues, and to that end, a recent educational practice management update was published in Clinical Gastroenterology and Hepatology by Erin Smith Aebel, JD, a health law specialist with Trenam Law in Tampa, Florida. Aebel has been a speaker at several national GI conferences and has addressed GI trainees on these issues in medical schools.

Erin Smith Aebel



“Healthcare regulation continues to evolve and it’s a complicated area,” Aebel told GI & Hepatology News. “Some physician investors in healthcare ventures see the potential profits but are not fully aware of how a physician’s license and livelihood could be affected by noncompliance.” 

Aebel has seen some medical business owners and institutions pushing physicians to their limits in order to maximize profits. “They’re failing to allow them the meaningful things that allow for a long-term productive and successful practice that provides great patient care,” she said. “A current issue I’m dealing with is employers’ taking away physicians’ administrative time and not respecting the work that is necessary for the physician to be efficient and provide great care,” she said. “If too many physicians get squeezed in this manner, they will eventually walk away from big employers to something they can better control.” 

Aebel noted that private-equity acquisitions of medical practices — a fast-growing US trend — are often targeted at quick profits and quick exits, which can be inconsistent with quality long-term patient care. “A question to be asked by physicians and patients is who is benefiting from this transaction?” she said. “Sometimes retired physicians can see a great benefit in private equity, but newer physicians can get tied up with a strong noncompete agreement. The best deals are ones that try to find wins for all involved, including patients.”

Many independent gastroenterologists focusing on the demands of daily practice are less aware than they should be of the legal and business administration sides. “I often get clients who come to me complaining about their contracts after they’ve signed them. I don’t have leverage to do as much for them,” she admitted.

From a business standpoint, gastroenterologists need to understand where they can negotiate for financial gain and control. These could relate to compensation and bonuses, as well as opportunities to invest in the practice, the practice management company, and possibly real estate or ambulatory surgery centers (ASCs).

Aebel’s overarching messages to gastroenterologists are as follows: “Be aware. Learn basic health law. Read your contracts before you sign them. And invest in good counsel before you sign agreements,” she said. “In addition, GI practitioners need to have a working knowledge of the federal Anti-Kickback Statute and the federal Stark Law and how they could be commonly applied in their practices.”

These are designed to protect government-funded patient care from monetary influence. The False Claims Act is another federal buttress against fraud and abuse, she said.

 

Update Details

Though not intended to be legal advice, Aebel’s update touches on several important medicolegal areas.

Stark Law on Self-Referrals

Gastroenterologists should be familiar with this federal law, a self-referral civil penalty statute regulating how physicians can pay themselves in practices that provide designated health services covered by federal healthcare programs such as Medicare or Medicaid.

For a Stark penalty to apply, there must be a physician referral to an entity (eg, lab, hospital, nutrition service, physiotherapy or radiotherapy center) in which the physician or a close family member has a financial interest.

Ambulatory Surgery Centers

Another common area vulnerable to federal fraud and abuse regulation is investment in ASCs. “Generally speaking, it is a felony to pay or be paid anything of value for Medicare or Medicaid business referrals,” Aebel wrote. This provision relates to the general restriction of the federal AKB statute.

A gastroenterologist referring Medicare patients to a center where that physician has an investment could technically violate this law because the physician will receive profit distributions from the referral. In addition to constituting a felony with potential jail time, violation of this statute is grounds for substantial civil monetary penalties and/or exclusion from the government coverage program.

Fortunately, Aebel noted, legal safe harbors cover many financial relationships, including investment in an ASC. The financial arrangement is protected from prosecution if it meets five safe harbor requirements, including nondiscriminatory treatment of government-insured patients and physician investment unrelated to a center’s volume or the value of referrals. If even one aspect is not met, that will automatically constitute a crime.

“However, the government will look at facts and circumstances to determine whether there was an intent to pay for a referral,” Aebel wrote.

The safe harbor designates requirements for four types of ASCs: surgeon-owned, single-specialty, multispecialty, and hospital/physician ASCs.

 

Private-Equity Investment

With mergers and acquisitions of US medical practices and networks by private-equity firms becoming more common, gastroenterologists need to be aware of the legal issues involved in such investment.

Most states abide by corporate practice of medicine doctrines, which prohibit unlicensed people from direct ownership in a medical practice. These doctrines vary by state, but their primary goal is to ensure that medical decisions are made solely based on patient care and not influenced by corporate interests. The aim is to shield the physician-patient relationship from commercial influence.

“Accordingly, this creates additional complicated structures necessary for private-equity investment in gastroenterology practices,” Aebel wrote. Usually, such investors will invest in a management services organization (MSO), which takes much of the practice’s value via management fees. Gastroenterologists may or may not have an opportunity to invest in the practice and the MSO in this scenario.

Under corporate practice of medicine doctrine, physicians must control the clinical aspects of patient care. Therefore, some states may have restrictions on private-equity companies’ control of the use of medical devices, pricing, medical protocols, or other issues of patient care.

“This needs to be considered when reviewing the investment documents and structural documents proposed by private equity companies,” the advisory stated. From a business standpoint, gastroenterologists need to understand where they can negotiate for financial gain and control over their clinical practice. “This could relate to their compensation, bonuses, and investment opportunities in the practice, the practice management company, and possibly real estate or ASCs.”

Dr. Camille Thélin



Offering a gastroenterologist’s perspective on the paper, Camille Thélin, MD, MSc, an associate professor in the Division of Digestive Diseases and Health at the University of South Florida, Tampa, Florida, who also practices privately, said, that “what Erin Aebel reminds us is that the business side of GI can be just as tricky as the clinical side. Ancillary services like capsule studies or office labs fall under strict Stark rules, ASC ownership has Anti-Kickback Law restrictions, and private-equity deals may affect both your paycheck and your autonomy.”

Thélin’s main takeaway advice is that business opportunities can be valuable but carry real legal risks if not structured correctly. “This isn’t just abstract compliance law — it’s about protecting one’s ability to practice medicine, earn fairly, and avoid devastating penalties,” she told GI & Hepatology News. “This article reinforces the need for proactive legal review and careful structuring of business arrangements so physicians can focus on patient care without stumbling into avoidable legal pitfalls. With the right legal structure, ancillaries, ASCs, and private equity can strengthen your GI practice without risking compliance.”

The bottom line, said Aebel, is that gastroenterologists already in private practice or considering entering one must navigate a complex landscape of compliance and regulatory requirements — particularly when providing ancillary services, investing in ASCs, or engaging with private equity.

Understanding the Stark law, the AKB statute, and the intricacies of private-equity investment is essential to mitigate risks and avoid severe penalties, the advisory stressed. By proactively seeking expert legal and business guidance, gastroenterologists can structure their financial and ownership arrangements in a compliant manner, safeguarding their practices while capitalizing on growth opportunities.

This paper listed no external funding. Neither Aebel nor Thélin had any relevant conflicts of interest.

From a business standpoint, gastroenterologists need to understand where they can negotiate for financial gain and control. These could relate to compensation and bonuses, as well as opportunities to invest in the practice, the practice management company, and possibly real estate or ambulatory surgery centers (ASCs).

Aebel’s overarching messages to gastroenterologists are as follows: “Be aware. Learn basic health law. Read your contracts before you sign them. And invest in good counsel before you sign agreements,” she said. “In addition, GI practitioners need to have a working knowledge of the federal Anti-Kickback Statute and the federal Stark Law and how they could be commonly applied in their practices.”

These are designed to protect government-funded patient care from monetary influence. The False Claims Act is another federal buttress against fraud and abuse, she said.

 

Update Details

Though not intended to be legal advice, Aebel’s update touches on several important medicolegal areas.

Stark Law on Self-Referrals

Gastroenterologists should be familiar with this federal law, a self-referral civil penalty statute regulating how physicians can pay themselves in practices that provide designated health services covered by federal healthcare programs such as Medicare or Medicaid.

For a Stark penalty to apply, there must be a physician referral to an entity (eg, lab, hospital, nutrition service, physiotherapy or radiotherapy center) in which the physician or a close family member has a financial interest.

Ambulatory Surgery Centers

Another common area vulnerable to federal fraud and abuse regulation is investment in ASCs. “Generally speaking, it is a felony to pay or be paid anything of value for Medicare or Medicaid business referrals,” Aebel wrote. This provision relates to the general restriction of the federal AKB statute.

A gastroenterologist referring Medicare patients to a center where that physician has an investment could technically violate this law because the physician will receive profit distributions from the referral. In addition to constituting a felony with potential jail time, violation of this statute is grounds for substantial civil monetary penalties and/or exclusion from the government coverage program.

Fortunately, Aebel noted, legal safe harbors cover many financial relationships, including investment in an ASC. The financial arrangement is protected from prosecution if it meets five safe harbor requirements, including nondiscriminatory treatment of government-insured patients and physician investment unrelated to a center’s volume or the value of referrals. If even one aspect is not met, that will automatically constitute a crime.

“However, the government will look at facts and circumstances to determine whether there was an intent to pay for a referral,” Aebel wrote.

The safe harbor designates requirements for four types of ASCs: surgeon-owned, single-specialty, multispecialty, and hospital/physician ASCs.

 

Private-Equity Investment

With mergers and acquisitions of US medical practices and networks by private-equity firms becoming more common, gastroenterologists need to be aware of the legal issues involved in such investment.

Most states abide by corporate practice of medicine doctrines, which prohibit unlicensed people from direct ownership in a medical practice. These doctrines vary by state, but their primary goal is to ensure that medical decisions are made solely based on patient care and not influenced by corporate interests. The aim is to shield the physician-patient relationship from commercial influence.

“Accordingly, this creates additional complicated structures necessary for private-equity investment in gastroenterology practices,” Aebel wrote. Usually, such investors will invest in a management services organization (MSO), which takes much of the practice’s value via management fees. Gastroenterologists may or may not have an opportunity to invest in the practice and the MSO in this scenario.

Under corporate practice of medicine doctrine, physicians must control the clinical aspects of patient care. Therefore, some states may have restrictions on private-equity companies’ control of the use of medical devices, pricing, medical protocols, or other issues of patient care.

“This needs to be considered when reviewing the investment documents and structural documents proposed by private equity companies,” the advisory stated. From a business standpoint, gastroenterologists need to understand where they can negotiate for financial gain and control over their clinical practice. “This could relate to their compensation, bonuses, and investment opportunities in the practice, the practice management company, and possibly real estate or ASCs.”

Dr. Camille Thélin



Offering a gastroenterologist’s perspective on the paper, Camille Thélin, MD, MSc, an associate professor in the Division of Digestive Diseases and Health at the University of South Florida, Tampa, Florida, who also practices privately, said, that “what Erin Aebel reminds us is that the business side of GI can be just as tricky as the clinical side. Ancillary services like capsule studies or office labs fall under strict Stark rules, ASC ownership has Anti-Kickback Law restrictions, and private-equity deals may affect both your paycheck and your autonomy.”

Thélin’s main takeaway advice is that business opportunities can be valuable but carry real legal risks if not structured correctly. “This isn’t just abstract compliance law — it’s about protecting one’s ability to practice medicine, earn fairly, and avoid devastating penalties,” she told GI & Hepatology News. “This article reinforces the need for proactive legal review and careful structuring of business arrangements so physicians can focus on patient care without stumbling into avoidable legal pitfalls. With the right legal structure, ancillaries, ASCs, and private equity can strengthen your GI practice without risking compliance.”

The bottom line, said Aebel, is that gastroenterologists already in private practice or considering entering one must navigate a complex landscape of compliance and regulatory requirements — particularly when providing ancillary services, investing in ASCs, or engaging with private equity.

Understanding the Stark law, the AKB statute, and the intricacies of private-equity investment is essential to mitigate risks and avoid severe penalties, the advisory stressed. By proactively seeking expert legal and business guidance, gastroenterologists can structure their financial and ownership arrangements in a compliant manner, safeguarding their practices while capitalizing on growth opportunities.

This paper listed no external funding. Neither Aebel nor Thélin had any relevant conflicts of interest.

Fecal Transplant Benefits in Primary C Difficile Infection Similar to Vancomycin

Article Type
Changed
Mon, 09/29/2025 - 15:10

Fecal microbiota transplantation (FMT), shown to be effective in the treatment of recurrent Clostridioides difficile infection (CDI), also shows significant benefit in the treatment of primary CDI, with efficacy that is comparable to the standard treatment of vancomycin, and in some measures, showing even stronger efficacy, new research showed.

“FMT, prepared and administered according to international guidelines, is an effective and safe treatment option for C difficile infections, which should be considered for all patients with the infection,” first author Frederik Emil Juul, MD, PhD, of the Clinical Effectiveness Research Group, University of Oslo, in Oslo, Norway, told GI & Hepatology News.

FMT even showed a numerical superiority to vancomycin, which, though not statistically significant, “indicates that FMT has the potential to change the current practice of antibiotic therapy and may establish FMT as a first-line treatment for primary CDI,” the authors further asserted in the study, published recently in the Annals of Internal Medicine.

In the treatment of antibiotic-associated colitis due to CDI, vancomycin or fidaxomicin are the standard therapies, yet up to 20% of patients experience one or more symptom recurrences following successful initial antibiotic treatment, prompting the need for continued antibiotic regimens, resulting in increased costs and potential adverse events, while contributing to antibiotic resistance.

FMT, designed to restore a normal functional colonic microenvironment with the transfer of a healthy person’s stool, though still somewhat controversial, has gained acceptance and favor in recent years in the treatment of recurrent CDI, however, research has been lacking on its efficacy in the treatment of primary CDI.

With a previous proof-of-concept trial and observational study showing promising results in primary CDI, Juul and colleagues conducted the current randomized, open-label noninferiority trial.

For the multi-center study, 100 adult patients with CDI, defined as C diff toxin in stool and at least three loose stools daily, and no previous CDI within 1 year prior to enrollment, were randomized at 20 hospitals in Norway to receive either FMT, administered as an enema, without antibiotic pretreatment, or oral vancomycin at a dose of 125 mg, four times daily for 10 days.

The patients had a median age of about 70 years; more than 40% of patients had a Charlson Comorbidity Index score of ≥ 4, indicating severe comorbidity, and a third had severe CDI.

With the trial showing favorable results, a data and safety monitoring board recommended stopping the trial for efficacy and noninferiority after about half of the planned enrollment was reached.

The primary endpoint of a clinical cure, defined as firm stools or less than three bowel movements daily and no disease recurrence within 60 days without additional treatment, was observed in 34 of 51 patients who received FMT (66.7%) compared with 30 of 49 of those receiving vancomycin (61.2%; difference, 5.4 percentage points; P for noninferiority < .001).

The results contradict the theory that response to FMT is 25 percentage points lower than response to vancomycin, the authors noted.

The proportion of patients with clinical cure at day 14 was 70.6% in the FMT group and 77.6% in the vancomycin group, and among those patients, two (5.6%) in the FMT group had disease recurrence compared with eight (21.1%) in the vancomycin group between days 15 and 60.

In the FMT group, 11 patients received additional treatment compared with four in the vancomycin group, predominantly oral vancomycin in both groups.

Despite the high rates of severe comorbidity among the patients at baseline, a subgroup analyses showed no significant differences in treatment effects based on factors including sex, age group, Charlson Comorbidity Index score, or CDI severity.

Importantly, there were also no significant differences in adverse events between the groups.

“Our results indicate that it is reasonable to treat patients with primary CDI with FMT and provide antibiotics only to patients with ongoing symptoms or recurrence after FMT,” the authors concluded.

 

FMT Faces Challenges in the US

FMT specifically consists of direct instillation of fecal matter to the upper gastrointestinal tract, via capsules or duodenal infusion, or the lower gastrointestinal tract via colonoscopy or enema.

While an AGA guideline issued in 2024 endorsed FMT for the prevention of recurrent, refractory, or fulminant CDI in select adults not responding to standard antibiotics, the association underscored important caveats, including a low quality of evidence, and concluded that FMT could not yet be recommended for other gastrointestinal conditions.

The treatment meanwhile has faced an uphill battle in the US. The provision of screened FMT inocula through the nonprofit OpenBiome, previously the country’s largest stool bank, was recently suspended amid FDA policy changes.

And while other commercial-grade biotherapeutic products Rebyota and Vowst, have received FDA approval, cost and insurance coverage can be significant barriers, said Elizabeth Hohmann, MD, of the Infectious Disease Division at Massachusetts General Hospital, Boston, in an editorial published with the study.

“Currently approved options are expensive and are not available to many who might benefit for various reasons, primarily cost,” she said.

 

Acceptance Higher in Europe

In Europe, and particularly Norway, acceptance of FMT for CDI and other indications has been more favorable, and while regulation of the treatment has varied among European countries, a new regulation to be implemented by the European Union in 2027 will improve standardization of the production, handling, storage, and other factors of FMT, Juul told GI & Hepatology News.

“I believe the new regulations will make the treatment more available to patients, and a standardization of the FMT production will make future trials more comparable and useful across countries,” he said.

Juul said he further expects that “our results will lower the threshold for choosing FMT as treatment in primary infections. I know that Denmark also gives FMT to patients with primary CDI.”

 

Quality of Life

Hohmann, who has treated many patients with recurrent CDI with FMT, noted that a key factor that should be underscored is how much better patients can feel after the treatment.

“Although there are no quality of life surveys in [the current study], had they been done, I suspect quality of life might have been higher in the FMT group; in my experience, people feel better after microbiome restoration.”

She added that her patients “report feeling much better, and that’s why I keep doing it,” she said. “I’ve had an 80-year-old patient tell me he’s going back to snow shoveling; another saying she can return to yoga classes.”

“When you have had bad gut microbiome dysbiosis that becomes normal, you feel a lot better,” Hohmann said.

In the treatment of primary CDI, however, Hohmann said the prospects, at least in the US, are likely slim.

“I do not believe that we in the United States will see FMT as a primary treatment of C difficile infection anytime soon,” she wrote in the editorial.

Nevertheless, Hohmann asserted that “FMT should remain available, with appropriate sources of carefully screened inocula for care and for further research into the many illnesses and therapies that are influenced by the health of the gut microbiome.”

This study received funding from the South-East Norway Health Trust. Hohmann had no disclosures to report.

Withdrawing Anti-TNF in IBD Remission: New Data

Article Type
Changed
Mon, 09/29/2025 - 15:11

Whether it’s safe to stop anti-TNF treatment in patients with inflammatory bowel disease (IBD) in remission remains unclear.

In the Spanish EXIT study, anti-TNF withdrawal in selected patients with IBD in clinical, endoscopic, and radiological remission had no impact on sustained clinical remission at 1 year, although objective markers of activity were higher in patients who stopped treatment.

The discontinuation of anti-TNF treatment “could be considered as an option” for a selected group of patients, said the authors led by Javier Gisbert, MD, PhD, with Autonomous University of Madrid.

However, the higher proportion of patients with elevated fecal calprotectin and significant endoscopic lesions at the end of follow-up “calls for caution and should be considered when discontinuing treatment in patients,” Gisbert and colleagues concluded.

The EXIT study results were published in the journal Gut (2025 Feb. doi: 10.1136/gutjnl-2024-333385).

 

Risky Business?

Anti-TNF drugs have reshaped IBD treatment but bring infection risks and costs, prompting interest in planned withdrawal after stable remission.

Yet prior evidence has been mixed. A meta-analysis of 27 studies suggested higher relapse after stopping anti-TNF therapy. However, the results were heterogeneous and most of the studies were retrospective, with a low number of patients and without a control group to compare with.

Clinical trials that have assessed the risk for relapse after discontinuation of anti-TNF therapy generally favored maintenance but had notable limitations.

The EXIT trial was conducted at 33 IBD units across Spain. A total of 140 patients in steroid-free clinical remission for ≥ 6 months on standard-dose infliximab or adalimumab were randomized (1:1) to either continue anti-TNF or switch to placebo matched to the drug they had been taking. All patients continued on immunomodulator therapy.

At 1 year, the proportion of patients with sustained clinical remission (primary outcome) was similar between patients who continued anti-TNF therapy and peers who stopped the medication (76% and 84%, respectively).

However, the proportion of patients with significant endoscopic lesions at the end of follow-up was higher in those who withdrew anti-TNF therapy (19% vs 8.5%; P = .01). Elevated fecal calprotectin (> 250 µg/g) was more common after withdrawal (33% vs 13%; P = .01).

Fecal calprotectin > 250 µg/g at baseline predicted lower odds of sustained remission and higher risk for losing remission — and was the only factor associated with lower likelihood of sustained remission.

 

Common Clinical Question

“When a patient starts an advanced biologic therapy, they often ask — will I be able to stop it?” Jean-Frederic Colombel, MD, director of the Inflammatory Bowel Disease Clinical Center at the Icahn School of Medicine at Mount Sinai, New York City, who wasn’t involved in the study, told GI & Hepatology News.

Dr. Jean-Frederic Colombel

Generally speaking, Colombel said he tells patients, “If the drug is working well and you are in deep remission, they should try to avoid stopping because there is a risk of relapse. And with relapse, we never know if the drug will work again and maybe we’ll have to switch to another medication.”

“It’s an individualized discussion and decision and patients who do opt to stop [anti-TNF therapy] need to be monitored closely,” Colombel said.

Colombel cautioned that the study had a relatively short 1-year follow-up and those that stopped anti-TNF therapy had evidence of recurrent inflammation.

“Even though it didn’t translate yet to clinical relapse, there were more patients with subclinical active disease in the group that stopped as compared to the group that continued,” Colombel said.

He also noted that in the SPARE trial of patients with Crohn’s disease in clinical remission, patients who stopped infliximab had a higher risk for relapse compared with patients who stopped azathioprine and those who continued the combination therapy.

The EXIT study was supported by grants from Instituto de Salud Carlos III, Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa and AbbVie. Gisbert reported serving as speaker, consultant, and advisory member for or receiving research funding from MSD, AbbVie, Pfizer, Kern Pharma, Biogen, Mylan, Takeda, Janssen, Roche, Sandoz, Celgene/Bristol Myers, Gilead/Galapagos, Lilly, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Tillotts Pharma, Chiesi, Casen Fleet, Gebro Pharma, Otsuka Pharmaceutical, Norgine and Vifor Pharma. Colombel had no relevant disclosures.

The discontinuation of anti-TNF treatment “could be considered as an option” for a selected group of patients, said the authors led by Javier Gisbert, MD, PhD, with Autonomous University of Madrid.

However, the higher proportion of patients with elevated fecal calprotectin and significant endoscopic lesions at the end of follow-up “calls for caution and should be considered when discontinuing treatment in patients,” Gisbert and colleagues concluded.

The EXIT study results were published in the journal Gut (2025 Feb. doi: 10.1136/gutjnl-2024-333385).

 

Risky Business?

Anti-TNF drugs have reshaped IBD treatment but bring infection risks and costs, prompting interest in planned withdrawal after stable remission.

Yet prior evidence has been mixed. A meta-analysis of 27 studies suggested higher relapse after stopping anti-TNF therapy. However, the results were heterogeneous and most of the studies were retrospective, with a low number of patients and without a control group to compare with.

Clinical trials that have assessed the risk for relapse after discontinuation of anti-TNF therapy generally favored maintenance but had notable limitations.

The EXIT trial was conducted at 33 IBD units across Spain. A total of 140 patients in steroid-free clinical remission for ≥ 6 months on standard-dose infliximab or adalimumab were randomized (1:1) to either continue anti-TNF or switch to placebo matched to the drug they had been taking. All patients continued on immunomodulator therapy.

At 1 year, the proportion of patients with sustained clinical remission (primary outcome) was similar between patients who continued anti-TNF therapy and peers who stopped the medication (76% and 84%, respectively).

However, the proportion of patients with significant endoscopic lesions at the end of follow-up was higher in those who withdrew anti-TNF therapy (19% vs 8.5%; P = .01). Elevated fecal calprotectin (> 250 µg/g) was more common after withdrawal (33% vs 13%; P = .01).

Fecal calprotectin > 250 µg/g at baseline predicted lower odds of sustained remission and higher risk for losing remission — and was the only factor associated with lower likelihood of sustained remission.

 

Common Clinical Question

“When a patient starts an advanced biologic therapy, they often ask — will I be able to stop it?” Jean-Frederic Colombel, MD, director of the Inflammatory Bowel Disease Clinical Center at the Icahn School of Medicine at Mount Sinai, New York City, who wasn’t involved in the study, told GI & Hepatology News.

Dr. Jean-Frederic Colombel

Generally speaking, Colombel said he tells patients, “If the drug is working well and you are in deep remission, they should try to avoid stopping because there is a risk of relapse. And with relapse, we never know if the drug will work again and maybe we’ll have to switch to another medication.”

“It’s an individualized discussion and decision and patients who do opt to stop [anti-TNF therapy] need to be monitored closely,” Colombel said.

Colombel cautioned that the study had a relatively short 1-year follow-up and those that stopped anti-TNF therapy had evidence of recurrent inflammation.

“Even though it didn’t translate yet to clinical relapse, there were more patients with subclinical active disease in the group that stopped as compared to the group that continued,” Colombel said.

He also noted that in the SPARE trial of patients with Crohn’s disease in clinical remission, patients who stopped infliximab had a higher risk for relapse compared with patients who stopped azathioprine and those who continued the combination therapy.

The EXIT study was supported by grants from Instituto de Salud Carlos III, Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa and AbbVie. Gisbert reported serving as speaker, consultant, and advisory member for or receiving research funding from MSD, AbbVie, Pfizer, Kern Pharma, Biogen, Mylan, Takeda, Janssen, Roche, Sandoz, Celgene/Bristol Myers, Gilead/Galapagos, Lilly, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Tillotts Pharma, Chiesi, Casen Fleet, Gebro Pharma, Otsuka Pharmaceutical, Norgine and Vifor Pharma. Colombel had no relevant disclosures.

Oral Microbes Tied to Pancreatic Cancer Risk

Mon, 09/29/2025 - 10:21

Could oral microbiome profiling help spot people at risk for pancreatic cancer?

It may be possible, according to a recent analysis published in JAMA Oncology.

Researchers found that a microbial risk score derived from oral wash samples may help identify people at an increased risk for pancreatic cancer, which could be a step toward earlier detection of the deadly malignancy.

“We identified 27 individual bacterial and fungal species significantly associated with pancreatic cancer development,” said Jiyoung Ahn, PhD, of NYU Grossman School of Medicine in New York City.

Jiyoung Ahn



“If validated, oral microbiome profiling could serve as a noninvasive biomarker to identify individuals at elevated risk who might benefit from enhanced surveillance,” Ahn told GI & Hepatology News by email.

Rates of pancreatic cancer are on the rise. But detecting the disease before it becomes unresectable has remained an elusive goal, and the US Preventive Services Task Force discourages screening of asymptomatic adults.

For their study, Ahn and her colleagues analyzed data from 122,000 participants who provided oral wash samples as part of two cohort studies conducted in the US. The researchers used whole-genome shotgun sequencing and internal transcribed spacer sequencing to identity the bacterial and fungal species in the samples, respectively.

Over a median follow-up of nearly 9 years, 445 people developed pancreatic cancer and were matched with 445 who did not. Three oral bacterial periodontal pathogens — Porphyromonas gingivalis (odds ratio [OR], 1.27), Eubacterium nodatum (OR, 1.42), and Parvimonas micra (OR, 1.36) — as well as the fungal genus Candida were all linked to significantly increased odds of developing pancreatic cancer.

In a bacteriome-wide scan, the researchers pinpointed another 20 oral bacteria associated with pancreatic cancer — eight with a decreased risk and 13 with an increased risk for the disease.

The researchers also calculated a microbial risk score, which was the weighted sum of the relative abundance of bacterial and fungal species. In a meta-analysis of data from the two cohorts, the microbial risk score derived from 23 bacterial species and four fungal species, including various Candida species, was associated with pancreatic cancer (multivariate OR per 1-SD increase in the score, 3.44; 95% CI, 2.63-4.51).

“The oral microbiota holds promise as a biomarker to identify individuals at high risk of pancreatic cancer, potentially enabling personalized pancreatic cancer prevention,” Ahn and her colleagues concluded.

But Gil Welch, MD, of Brigham and Women’s Hospital in Boston, who has written about screening for decades, isn’t so sure.

Given the “impressive volume of information” included in the analysis, “it is not surprising that the investigators are able to create a microbial risk score (based on 27 species of bacteria and fungi) that is highly related to pancreatic cancer,” Welch said. “The authors are careful to emphasize these are associations, not causal relationships.”

But even if the relationship were causal, finding more people with the malignancy can also have downsides, said Welch.

In a study out last year, Welch and colleagues found that while the incidence of pancreatic cancer among young Americans has been rising, mortality rates in this demographic haven’t budged, suggesting a potential for overdiagnosis.

“Screening for pancreatic cancer has never been shown to reduce pancreatic cancer mortality,” Welch told GI & Hepatology News. “Why screen large swaths of the population simply to enumerate ‘risk factors’ for an unproven benefit that, at best, could help only a few? Meanwhile, the burdens for everyone else are real: the mental and financial strains of ‘high risk’ labels, false alarms, and endless follow-ups. It’s a recipe to make us all worried sick — and poorer.”

Ahn reported having no disclosures. Welch reported receiving royalties from three books including “Should I be tested for cancer?”

How Chronic Stress Disrupts the Gut Microbiome

Article Type
Changed
Thu, 09/25/2025 - 16:10

Chronic psychological stress is common. A 2023 survey revealed that about one quarter of US adults reported high stress levels, and three quarters reported that chronic stress affects their daily lives.

Emerging evidence suggests that chronic stress not only exacts a high toll on mental health but also can wreak havoc on all levels of gastrointestinal (GI) functioning, all the way down to the microbiome.

“Chronic stress can change the diversity and composition of the gut microbiome and essentially tips us toward an imbalance or dysbiosis,” Aasma Shaukat, MD, MPH, AGAF, gastroenterologist with NYU Langone Health and director of GI Outcomes Research, Gastroenterology at NYU Grossman School of Medicine in New York City, said in an interview with GI & Hepatology News.

Dr. Aasma Shaukat



“This basically means that the normal balance of microorganisms that essentially we think are beneficial gets reduced, and the colonies considered to be more harmful proliferate,” she explained.

 

What Does the Science Tell Us?

Numerous studies published in the past 5 years have linked chronic stress to modest but reproducible shifts in the composition of the microbiome.

A study of frontline healthcare workers during COVID-19 revealed that the pandemic was associated with significant depression, anxiety, and stress, as well as gut dysbiosis that persisted for at least half a year.

Notably, healthcare workers had low gut alpha diversity, indicating a less resilient and diverse microbiome, a state often associated with dysbiosis and increased risk for various diseases and negative health outcomes.

A two-cohort study of healthy adults found higher alpha diversity in those reporting low stress levels. It also found a link between stress and enriched levels of Escherichia/Shigella, an overgrowth of which has been linked to various conditions, including inflammatory bowel disease.

In addition, a 2023 systematic review of human studies concluded that stress is associated with changes in specific genera — namely reductions in gut-healthy Lachnospira/Lachnospiraceae and Phascolarctobacterium, which produce beneficial short-chain fatty acids that support the health of the intestinal lining and modulate the immune system.

Stress during specific life stages also appears to alter the gut microbiome.

For example, in a study of postpartum women, those at an increased risk for parenting stress showed lower alpha diversity on the Shannon diversity index.

Research involving mother-child pairs tied adversity — such as maltreatment of the mother during her childhood, prenatal anxiety, and hardship in the child’s early life — to distinct microbiome profiles in 2-year-olds, supporting a stress-microbiome pathway relevant to socioemotional outcomes, the authors said.

Emerging evidence indicates a link between the gut microbiome and posttraumatic stress disorder (PTSD).

A recent systematic review found differences in gut microbial taxa between individuals with PTSD and trauma-exposed controls without PTSD. A separate analysis pointed to a potential causal impact of gut microbiomes on the development of PTSD.

 

Mechanisms Behind the Link

Stress interferes with the brain’s production of neurotransmitters, such as serotonin, which controls anxiety, mood, sleep, and many other functions in the brain, Shaukat told GI & Hepatology News.

“But serotonin also crosses the blood-brain barrier, and actually, the gut has more serotonin receptors than the brain, so an imbalance of serotonin can actually affect the gut microbiome through signaling at the neurotransmitter level,” Shaukat explained.

Stress can also affect sleep, and sleep itself has regulatory properties for gut bacteria, Shaukat noted.

“Stress also lowers our immunity, and this can make the gut barrier susceptible or permeable to bacterial toxins that can pass through and breach the gut barrier and be released into the bloodstream, which can trigger inflammation,” Shaukat explained.

 

Implications for Patient Care

The gut-brain-microbiome axis remains an emerging field of study. “We’re learning more and more about this, and we need to because the microbial colonies are so diverse and we haven’t nailed it down yet,” Shaukat said.

In the meantime, what can clinicians tell patients?

Aside from managing stress, which “is easier said than done,” patients can improve their diet, Shaukat said.

“What we tell patients is to essentially increase their intake of gut-friendly foods that preferentially grow the bacterial colonies that are beneficial for us,” Shaukat said. This includes fermented foods, yogurt, kimchi, chia seeds, kombucha, pickled vegetables, and whole grains.

A recent randomized controlled trial of healthy adults found a “psychobiotic diet” — a diet high in prebiotic and fermented foods — was associated with less perceived stress and subtle beneficial shifts in microbial composition.

“These foods can help keep the gut in good health and may actually also reduce or mitigate some of the effects of stress,” Shaukat said.

“Eating well is something I think we should all think about and maybe prioritize when we’re going through a stressful situation or looking to kind of mitigate the effects of stress and the anxiety and depression it can cause,” she advised.

Shaukat said she also encourages patients to engage in regular physical activity, which benefits the gut microbiome by helping to regulate gut motility. Exercise can also boost mood and help relieve stress.

“A balanced Mediterranean diet and regular activity is truly the secret for gut health,” Shaukat said.

Patients may be tempted by the probiotic supplements lining drugstore shelves, but there “isn’t great evidence for probiotic supplements,” she said. “What we can get from dietary sources far outweighs what can be put in a pill.”

Shaukat disclosed having no relevant disclosures.

Notably, healthcare workers had low gut alpha diversity, indicating a less resilient and diverse microbiome, a state often associated with dysbiosis and increased risk for various diseases and negative health outcomes.

A two-cohort study of healthy adults found higher alpha diversity in those reporting low stress levels. It also found a link between stress and enriched levels of Escherichia/Shigella, an overgrowth of which has been linked to various conditions, including inflammatory bowel disease.

In addition, a 2023 systematic review of human studies concluded that stress is associated with changes in specific genera — namely reductions in gut-healthy Lachnospira/Lachnospiraceae and Phascolarctobacterium, which produce beneficial short-chain fatty acids that support the health of the intestinal lining and modulate the immune system.

Stress during specific life stages also appears to alter the gut microbiome.

For example, in a study of postpartum women, those at an increased risk for parenting stress showed lower alpha diversity on the Shannon diversity index.

Research involving mother-child pairs tied adversity — such as maltreatment of the mother during her childhood, prenatal anxiety, and hardship in the child’s early life — to distinct microbiome profiles in 2-year-olds, supporting a stress-microbiome pathway relevant to socioemotional outcomes, the authors said.

Emerging evidence indicates a link between the gut microbiome and posttraumatic stress disorder (PTSD).

A recent systematic review found differences in gut microbial taxa between individuals with PTSD and trauma-exposed controls without PTSD. A separate analysis pointed to a potential causal impact of gut microbiomes on the development of PTSD.

 

Mechanisms Behind the Link

Stress interferes with the brain’s production of neurotransmitters, such as serotonin, which controls anxiety, mood, sleep, and many other functions in the brain, Shaukat told GI & Hepatology News.

“But serotonin also crosses the blood-brain barrier, and actually, the gut has more serotonin receptors than the brain, so an imbalance of serotonin can actually affect the gut microbiome through signaling at the neurotransmitter level,” Shaukat explained.

Stress can also affect sleep, and sleep itself has regulatory properties for gut bacteria, Shaukat noted.

“Stress also lowers our immunity, and this can make the gut barrier susceptible or permeable to bacterial toxins that can pass through and breach the gut barrier and be released into the bloodstream, which can trigger inflammation,” Shaukat explained.

 

Implications for Patient Care

The gut-brain-microbiome axis remains an emerging field of study. “We’re learning more and more about this, and we need to because the microbial colonies are so diverse and we haven’t nailed it down yet,” Shaukat said.

In the meantime, what can clinicians tell patients?

Aside from managing stress, which “is easier said than done,” patients can improve their diet, Shaukat said.

“What we tell patients is to essentially increase their intake of gut-friendly foods that preferentially grow the bacterial colonies that are beneficial for us,” Shaukat said. This includes fermented foods, yogurt, kimchi, chia seeds, kombucha, pickled vegetables, and whole grains.

A recent randomized controlled trial of healthy adults found a “psychobiotic diet” — a diet high in prebiotic and fermented foods — was associated with less perceived stress and subtle beneficial shifts in microbial composition.

“These foods can help keep the gut in good health and may actually also reduce or mitigate some of the effects of stress,” Shaukat said.

“Eating well is something I think we should all think about and maybe prioritize when we’re going through a stressful situation or looking to kind of mitigate the effects of stress and the anxiety and depression it can cause,” she advised.

Shaukat said she also encourages patients to engage in regular physical activity, which benefits the gut microbiome by helping to regulate gut motility. Exercise can also boost mood and help relieve stress.

“A balanced Mediterranean diet and regular activity is truly the secret for gut health,” Shaukat said.

Patients may be tempted by the probiotic supplements lining drugstore shelves, but there “isn’t great evidence for probiotic supplements,” she said. “What we can get from dietary sources far outweighs what can be put in a pill.”

Shaukat disclosed having no relevant disclosures.

IBD 101: Intensive Course for GI Fellows Boosts Clinical Confidence

Article Type
Changed
Thu, 09/25/2025 - 13:12

An intensive 1-day overview course in inflammatory bowel disease (IBD) continues to attract large numbers of first-year gastrointestinal(GI) fellows across the country.

Results from the initial pilot program in 2019, called “IBD 101: Physicians and Patients Providing Pearls and Perspectives” are outlined in Inflammatory Bowel Diseases by Lisa Malter, MD, AGAF, a professor of medicine in the Division of Gastroenterology at NYU Langone Grossman School of Medicine, New York City, and colleagues.

Dr. Lisa Malter



The course, conducted by Malter at NYU Langone’s simulation center, was designed to increase fellows’ early exposure to the complexities of IBD and its diagnosis and management in the context of rapidly changing therapies and variability across US GI training programs. The authors reported that the 2019 program was well received, with attendees showing “increased comfort and sustained benefit” in discussing IBD management with patients. Notably, participants’ increased comfort levels in broaching IBD topics persisted 3 years after the course compared with that of nonparticipating peers, pointing to potential improved patient care after completion of training.

“At this point, 1 in every 100 GI patients has IBD. It’s one of the more complex GI conditions and its incidence and prevalence are increasing globally,” Malter told GI & Hepatology News. Prevalence rates in the US are reportedly as high as 464.5 per 100,000 persons.

“In addition, its management has become more complicated with newer medications and treatments coming on stream,” she said. “An educational gap exists.”

 

The Program

The course provided an intimate, interactive format with national experts in the field serving as faculty. Course objectives included basic, introductory information on the diagnosis, treatment, and management of IBD; early exposure to IBD as a subspecialty to allow registrants to make informed career decisions; and information about other educational opportunities.

The course was designed to raise participants’ comfort levels in discussing seven topics with patients, including the need for surgery, IBD in pregnancy, treatment escalation in different disease scenarios, and lack of treatment response.

The three-part course, featuring case scenarios, was offered in person to 60 fellows selected by regional GI fellowship program directors and course faculty, which consisted of a director, three codirectors, and 14 local and national IBD experts. A half-day training session for faculty was held immediately before the course.

In September 2019, the first 32 fellows from Accreditation Council for Graduate Medical Education-accredited programs participated in IBD 101. A total of 49 (89%) of 55 participants completed presession and immediate postsession surveys.

In the 3-year follow-up survey, among 36 fellows, of whom 21 (58%) attended IBD 101 and 15 (42%) did not, attendees reported overall IBD confidence and equivalent or higher levels of comfort in discussing each of seven topics.

Among the specific survey findings: 

  • 100% said the course had improved their ability to effectively treat and manage patients
  • A higher proportion of attendees strongly agreed with having comfort in discussing pregnancy in IBD (43% vs 13%; P = .08) 
  • A statistically significant proportion strongly agreed with having comfort in discussing loss of response to biologics (62% vs 27%; P = .049)
  • 98% reported increased interest in exploring IBD during fellowship
  • 100% noted improved understanding of supplemental opportunities to learn about IBD
  • 96% would strongly recommend this course to future GI fellows

Further testimony to the effectiveness of the ongoing course, said Malter, is that the version offered in 2024 attracted 425 GI fellows from across the country. “That’s about 90% of US GI fellows,” she said.

Offering an outsider’s perspective on the results of the course, Ashwin N. Ananthakrishnan, MBBS, MPH, AGAF, a director or the Crohn’s and Colitis Center at Massachusetts General Hospital in Boston, said, “It’s a useful update. It’s always good to see benefits from educational courses.” He expressed caution, however, “in that a small subset of GI fellows always selects toward those with greater IBD interest. Consequently, they likely have participated in several other IBD education activities in the intervening 3 years — so one can’t attribute benefit to this course alone.”

Ashwin N. Ananthakrishnan



And while one effect of such courses may to increase the number of IBD-interested trainees, their role in providing IBD education to gastroenterologists who will not specialize in IBD is more important, Ananthakrishnan added. “These general gastroenterologists are going to be managing a lot of the IBD in the community, so in my opinion, ensuring they are comfortable with caring for IBD patients optimally is more important than training IBD specialists, who have many opportunities for education.”

In collaboration with the American College of Gastroenterology, the course is open to all first-year GI fellows training in North America. The most recent program was held on September 13, 2025.

This paper received no specific funding. The IBD course has been supported by unrestricted educational grants from Pfizer and Takeda Pharmaceuticals and sponsorships from AbbVie, Janssen, and Prometheus Labs.Malter reported receiving educational grants from AbbVie, Janssen, Pfizer, and Takeda; serving as a consultant for Abbvie and Pharmacosmos; and serving on the advisory boards for AbbVie, Bristol Myers Squibb, Celltrion, Janssen, Merck, and Takeda. Multiple coauthors disclosed similar relationships with numerous private-sector companies.

Could a Clinical Decision Support Tool Improve Outcomes in Pediatric Diarrhea?

Article Type
Changed
Wed, 09/24/2025 - 09:46

qualitative study of the use of a clinical decision support tool in pediatric diarrhea identified the expectations of clinicians and the concerns of parents surrounding the tool’s use.

“Clinical decision support tools are designed to assist clinicians in making informed and accurate diagnostic and prognostic decisions using available characteristics of the patient and the larger context,” Anna Jones, MD, MPH, and her colleagues wrote in JAMA Network Open.

Jones is in the Department of Pediatrics at the University of Utah School of Medicine in Salt Lake City.

Jones and her coauthors concluded such a tool had the potential to improve evidence-based testing in pediatric diarrhea and help clinicians communicate clearly to parents the etiology of their child’s illness. Parents in the study, however, expressed skepticism over the tool, voicing concerns that physicians might over-rely on its algorithms.

The authors said that thanks to the development of multiplex polymerase chain reaction (PCR) panels for gastroenteritis, it is now possible to quickly identify up to 22 different pathogens from stool samples. What is lacking, they suggested, are protocols for knowing when to test for these pathogens.

“Although the Infectious Diseases Society of America 2017 clinical practice guidelines for the diagnosis and management of infectious diarrhea provide broad recommendations for when diarrhea-related diagnostics should be used, clear guidelines specific to the use of multiplex PCR panels do not exist,” Jones and her coauthors wrote, adding that misusing the diagnostics, however, “can lead to inappropriate antibiotic use and excess financial burdens.”

Meanwhile, communication breakdowns in the patient-doctor relationship are a leading contributor to diagnostic errors, according to the Agency for Healthcare Research and Quality. Subsequently, the National Academy of Medicine has recommended that healthcare professionals seek to engage patients and their families in the diagnostic process.

With these factors in mind, Jones and her colleagues recruited parents who had sought care for their child’s diarrhea and clinicians who routinely treat children with diarrhea. The recruits came from five urgent care sites and one emergency department (ED), all in Utah. Participants were interviewed between June 15, 2023, and January 24, 2025.

In all, the authors interviewed 44 parents (40 women; median age, 34 years). One parent (2%) identified as Asian, two (5%) as Black or African American, 15 (34%) as Hispanic or Latin, and 22 (50%) as White individuals. The remaining four participants (9%) were of unknown race and ethnicity. Most parents spoke English as their primary language (40 [91%]).

Among the 16 clinicians, 10 were physicians and six were nurse practitioners or physician associates. Eleven of the 16 were women and the group had a median age of 42 years. Fourteen clinicians (88%) self-identified as White individuals and two (13%) had unknown race and ethnicity.

All were interviewed on their management of pediatric diarrhea and about their expectations for diagnostic testing and treatment of the condition, as well as the perceived utility of a clinical decision support tool.

Jones and colleagues identified three motivations among parents who sought clinical care for a child with diarrhea. The first was reassurance, which the authors said included validation for what the parents were already doing to care for their child.

The second motivation was to obtain insight into the etiology of their child’s symptoms. “Many believed that diagnostic testing to identify the specific etiology of the illness would be useful. Parents indicated that knowing the etiology would offer desired reassurance and potentially inform treatment decisions,” Jones and her coauthors wrote.

Lastly, parents sought appropriate treatment and symptom relief.

Many clinicians acknowledged the benefits of a clinical decision support tool for help with evidence-based decision-making during diagnosis and to facilitate communication with families. However, they expressed skepticism over the use of diagnostics for etiology, noting that disease management was not dependent upon knowing it.

Some clinicians said many families expected a test. “Even if I don’t think that a GI [gastrointestinal] stool study is necessary, there are situations where…a family is not going to leave the [ED] happy without one. And so I probably order them sometimes when they’re not truly indicated,” a physician reported in the interview.

“That said,” Jones and her coauthors wrote, “clinicians thought that diagnostic testing for pediatric diarrhea was generally not warranted, except in unique cases [such as] bloody stools, prolonged duration of diarrhea, or travel history.”

Many clinicians thought a decision-making tool might help build trust and rapport with the patient’s family, reassuring them their child is getting evidence-based care.

“It just adds to that shared decision-making model. I think it adds trust…I think it does kind of back up our ability to defend why we’re doing what we’re doing,” reported one surveyed ED physician.

Parents were mostly wary of the potential use of a clinical decision-making tool. Jones and colleagues reported that in addition to some clinicians, “several parents expressed concerns that a tool does not account for nuances and would lead to ‘generalizing every kid’ (said the father of a child aged 1-3 years), as opposed to providing patient-centered care.”

Parents also said they worried a clinician would not reply upon their own clinical judgement if they had a diagnostic tool.

Jones and her colleagues concluded that before implementing a clinical decision support tool in pediatric diarrhea, strategies are necessary to, “resolve tension in care expectations, facilitate diagnostic stewardship, and optimize care.”

In an accompanying editorialKC Coffey, MD, MPH, concluded that the study by Jones and colleagues suggests that adapting such tools to incorporate parental expectations, “could facilitate patient engagement in the diagnostic process and increase acceptance of [using these tools for] decisions. Such discussions might also raise awareness of the potential harms of over testing.” Coffey is an epidemiologist and infectious disease physician at the University of Maryland in Baltimore.

Elizabeth Dobler, MD, who was not involved in the study, told GI & Hepatology News that “as the number of available tests continues to grow, stewardship is becoming more relevant than ever. Families may not always realize the downsides of unnecessary testing — such as false positives, avoidable procedures, or added risks — and part of our responsibility is to help them understand both the potential benefits and the potential harms of these tests.”

Dobler is the medical director for clinical decision support in the Department of Clinical Informatics at Ann & Robert H. Lurie Children’s Hospital of Chicago, Chicago.

Clinical decision support tools are helpful in the clinical setting, Dobler said because “they give providers quick access to the most relevant information needed for decision-making. This includes patient-specific details — symptoms, history, labs, and vitals” as well as the characteristics and downsides of the tests. In an ideal world, she said, clinicians would consider these data for every patient.

Dobler cautioned however, that, “it’s important to stress that these tools don’t replace clinical judgment — the provider still evaluates the patient, considers the clinical context, and incorporates the family’s preferences. But as a complement to that process, I believe these tools are very valuable.”

Lastly, Dobler said that transparency is key to helping parents overcome their hesitancy regarding these tools.

Jones, Coffey, and Dobler reported no relevant financial disclosures.

Jones and her colleagues concluded that before implementing a clinical decision support tool in pediatric diarrhea, strategies are necessary to, “resolve tension in care expectations, facilitate diagnostic stewardship, and optimize care.”

In an accompanying editorialKC Coffey, MD, MPH, concluded that the study by Jones and colleagues suggests that adapting such tools to incorporate parental expectations, “could facilitate patient engagement in the diagnostic process and increase acceptance of [using these tools for] decisions. Such discussions might also raise awareness of the potential harms of over testing.” Coffey is an epidemiologist and infectious disease physician at the University of Maryland in Baltimore.

Elizabeth Dobler, MD, who was not involved in the study, told GI & Hepatology News that “as the number of available tests continues to grow, stewardship is becoming more relevant than ever. Families may not always realize the downsides of unnecessary testing — such as false positives, avoidable procedures, or added risks — and part of our responsibility is to help them understand both the potential benefits and the potential harms of these tests.”

Dobler is the medical director for clinical decision support in the Department of Clinical Informatics at Ann & Robert H. Lurie Children’s Hospital of Chicago, Chicago.

Clinical decision support tools are helpful in the clinical setting, Dobler said because “they give providers quick access to the most relevant information needed for decision-making. This includes patient-specific details — symptoms, history, labs, and vitals” as well as the characteristics and downsides of the tests. In an ideal world, she said, clinicians would consider these data for every patient.

Dobler cautioned however, that, “it’s important to stress that these tools don’t replace clinical judgment — the provider still evaluates the patient, considers the clinical context, and incorporates the family’s preferences. But as a complement to that process, I believe these tools are very valuable.”

Lastly, Dobler said that transparency is key to helping parents overcome their hesitancy regarding these tools.

Jones, Coffey, and Dobler reported no relevant financial disclosures.

qualitative study of the use of a clinical decision support tool in pediatric diarrhea identified the expectations of clinicians and the concerns of parents surrounding the tool’s use.

“Clinical decision support tools are designed to assist clinicians in making informed and accurate diagnostic and prognostic decisions using available characteristics of the patient and the larger context,” Anna Jones, MD, MPH, and her colleagues wrote in JAMA Network Open.

Jones is in the Department of Pediatrics at the University of Utah School of Medicine in Salt Lake City.

Jones and her coauthors concluded such a tool had the potential to improve evidence-based testing in pediatric diarrhea and help clinicians communicate clearly to parents the etiology of their child’s illness. Parents in the study, however, expressed skepticism over the tool, voicing concerns that physicians might over-rely on its algorithms.

The authors said that thanks to the development of multiplex polymerase chain reaction (PCR) panels for gastroenteritis, it is now possible to quickly identify up to 22 different pathogens from stool samples. What is lacking, they suggested, are protocols for knowing when to test for these pathogens.

“Although the Infectious Diseases Society of America 2017 clinical practice guidelines for the diagnosis and management of infectious diarrhea provide broad recommendations for when diarrhea-related diagnostics should be used, clear guidelines specific to the use of multiplex PCR panels do not exist,” Jones and her coauthors wrote, adding that misusing the diagnostics, however, “can lead to inappropriate antibiotic use and excess financial burdens.”

Meanwhile, communication breakdowns in the patient-doctor relationship are a leading contributor to diagnostic errors, according to the Agency for Healthcare Research and Quality. Subsequently, the National Academy of Medicine has recommended that healthcare professionals seek to engage patients and their families in the diagnostic process.

With these factors in mind, Jones and her colleagues recruited parents who had sought care for their child’s diarrhea and clinicians who routinely treat children with diarrhea. The recruits came from five urgent care sites and one emergency department (ED), all in Utah. Participants were interviewed between June 15, 2023, and January 24, 2025.

In all, the authors interviewed 44 parents (40 women; median age, 34 years). One parent (2%) identified as Asian, two (5%) as Black or African American, 15 (34%) as Hispanic or Latin, and 22 (50%) as White individuals. The remaining four participants (9%) were of unknown race and ethnicity. Most parents spoke English as their primary language (40 [91%]).

Among the 16 clinicians, 10 were physicians and six were nurse practitioners or physician associates. Eleven of the 16 were women and the group had a median age of 42 years. Fourteen clinicians (88%) self-identified as White individuals and two (13%) had unknown race and ethnicity.

All were interviewed on their management of pediatric diarrhea and about their expectations for diagnostic testing and treatment of the condition, as well as the perceived utility of a clinical decision support tool.

Jones and colleagues identified three motivations among parents who sought clinical care for a child with diarrhea. The first was reassurance, which the authors said included validation for what the parents were already doing to care for their child.

The second motivation was to obtain insight into the etiology of their child’s symptoms. “Many believed that diagnostic testing to identify the specific etiology of the illness would be useful. Parents indicated that knowing the etiology would offer desired reassurance and potentially inform treatment decisions,” Jones and her coauthors wrote.

Lastly, parents sought appropriate treatment and symptom relief.

Many clinicians acknowledged the benefits of a clinical decision support tool for help with evidence-based decision-making during diagnosis and to facilitate communication with families. However, they expressed skepticism over the use of diagnostics for etiology, noting that disease management was not dependent upon knowing it.

Some clinicians said many families expected a test. “Even if I don’t think that a GI [gastrointestinal] stool study is necessary, there are situations where…a family is not going to leave the [ED] happy without one. And so I probably order them sometimes when they’re not truly indicated,” a physician reported in the interview.

“That said,” Jones and her coauthors wrote, “clinicians thought that diagnostic testing for pediatric diarrhea was generally not warranted, except in unique cases [such as] bloody stools, prolonged duration of diarrhea, or travel history.”

Many clinicians thought a decision-making tool might help build trust and rapport with the patient’s family, reassuring them their child is getting evidence-based care.

“It just adds to that shared decision-making model. I think it adds trust…I think it does kind of back up our ability to defend why we’re doing what we’re doing,” reported one surveyed ED physician.

Parents were mostly wary of the potential use of a clinical decision-making tool. Jones and colleagues reported that in addition to some clinicians, “several parents expressed concerns that a tool does not account for nuances and would lead to ‘generalizing every kid’ (said the father of a child aged 1-3 years), as opposed to providing patient-centered care.”

Parents also said they worried a clinician would not reply upon their own clinical judgement if they had a diagnostic tool.

Are Probiotics for Pouchitis Prevention Worth the Cost?

Article Type
Changed
Wed, 09/24/2025 - 13:06

An eight-strain probiotic has been shown to reduce the risk for pouchitis in patients with ulcerative colitis who undergo ileal pouch anal anastomosis (IPAA), but its cost-effectiveness depends on relapse risk and may only be justified in patients who experience frequent relapses of pouchitis, a new analysis showed.

“Our findings highlight that while probiotic treatments can reduce the risk of this complication, their high costs limit their overall value for most patients,” lead author Gaurav Syal, MD, a gastroenterologist at UCLA Health, said in a statement.

“Our analysis can help guide shared decision-making between patients, clinicians, and payers to ensure resources are used where they can provide the most benefit,” Syal added.

The study was published online in Gastro Hep Advances.

 

Common Complication After Ulcerative Colitis Surgery

Pouchitis is a common complication in patients with ulcerative colitis who undergo restorative proctocolectomy with IPAA, with a cumulative incidence of around 48% at 2 years and 80% at 30 years.

Many patients who experience pouchitis have a single episode and respond well to short antibiotic courses. However, others develop recurrent or relapsing pouchitis, and 17% progress to a chronic form that can become dependent on antibiotics or refractory to antibiotics.

An eight-strain probiotic was shown to be effective in primary and secondary prevention of pouchitis in randomized, placebo-controlled trials.

Syal and colleagues sought to determine whether it’s worth the cost.

They constructed decision-tree models with Markov simulations to compare the risk for initial development and recurrence of pouchitis over a 2-year period between no prophylaxis and daily use of the eight-strain probiotic.

In the primary prophylaxis model, the cycle length was 2 weeks and pouchitis treatment sequence was ciprofloxacinmetronidazole and ciprofloxacin-tinidazole. In the secondary prophylaxis model, the cycle length was 4 weeks and pouchitis treatment sequence was initially the same as the primary prophylaxis model with the addition of vedolizumab and infliximab.

Costs were calculated from a US third-party payer perspective, using a willingness-to-pay threshold of $100,000 per quality-adjusted life year (QALY).

For primary prevention, the probiotic slightly increased QALYs compared with no probiotic (0.927 vs 0.918) but at a far higher cost ($2223 vs $299), resulting in an incremental cost-effectiveness ratio (ICER) of $236,076 per QALY — well above the accepted threshold.

In patients with infrequent relapses, probiotic use was slightly more effective than no use of probiotic (cumulative QALYs, 1.26 vs 1.24) but more expensive ($3370 vs $557), yielding an ICER of $153,011 per QALY — again above the accepted threshold.

However, sensitivity analyses revealed that the probiotic was cost-effective in patients with frequent relapsing pouchitis — defined as two or more episodes per year.

In this subgroup, the ICER dropped below the willingness-to-pay threshold of $100,000 per QALY, and in some scenarios, the probiotic even became the dominant strategy, meaning it was both more effective and less costly than no prophylaxis, the researchers noted.

Current guidelines from AGA on managing pouchitis suggest using probiotics to prevent recurrent episodes of pouchitis with a caveat that those who experience infrequent episodes may choose to avoid secondary prevention strategies.

“Our findings supplement the guidelines by confirming that the eight-strain probiotics can be cost-effective in frequent relapsing not in infrequent relapsing pouchitis,” the authors wrote.

They also noted that the probiotic cost itself was the biggest driver of results, accounting for 95% of the total cost in the primary prevention model. According to their analysis, reducing its price by half could make it a cost-effective option more broadly.

They also noted that probiotic prophylaxis could be cost-effective for patients at higher-than-average risk, such as those with primary sclerosing cholangitis (PSC), who have 4.2 times higher odds of developing pouchitis than peers without PSC.

But they cautioned that “further research is warranted on the effectiveness of the eight-strain probiotic for primary prevention of pouchitis in patients with ulcerative colitis and IPAA and PSC.”

The study had no financial support. Syal reported receiving research support from Pfizer.

Bariatric Surgery May Lower Long-Term CKD Risk

Article Type
Changed
Tue, 09/23/2025 - 09:17

Bariatric surgery was associated with higher short-term risks for acute kidney injury (AKI) and nephrolithiasis but lower long-term risks for chronic kidney disease (CKD) and kidney failure with replacement therapy (KFRT), according to a population-based study in Denmark.

Writing in BMC Nephrology, researchers reported patients with bariatric surgery had an increased 1-year risk for AKI and 10-year risk for nephrolithiasis, alongside a decreased 10-year risk for CKD (stages G3-5) and KFRT, compared with matched patients diagnosed with overweight/obesity who did not undergo surgery.

 

A Closer Look

Using national registry data, the team identified all adults who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between January 1, 2006, and December 31, 2018. Each patient was age- and sex-matched (1:5) to patients with hospital-diagnosed overweight/obesity without bariatric surgery. Researchers also compared results against a population cohort matched solely by age and sex. Outcomes included cumulative risks for AKI, nephrolithiasis, CKD (G3-G5), and KFRT.

The cohort comprised 18,827 surgical patients (17,200 RYGB and 1627 SG) and 94,135 matched comparators. Median age was 41 years, 76% were women, and the median follow-up was 8.1 years. At baseline, the median estimated glomerular filtration rate (eGFR) was comparable (103 mL/min/1.73 m2) between both surgery and overweight/obesity control groups, as were A1c levels. There were fewer comorbidities in the population cohort matched only by age and sex than in the overweight/obesity comparison cohort.

Using multivariable Cox regression analyses, the researchers found the 1-year risk for AKI following bariatric surgery was 2.7%. At 10 years, risks were 3.5% for nephrolithiasis, 0.4% for CKD, and 0.2% for KFRT.

Adjusted hazard ratios (HRs) after bariatric surgery vs without bariatric surgery were higher for AKI (HR, 1.63) and nephrolithiasis (HR, 1.73) and lower for CKD (HR, 0.41) and KFRT (HR, 0.63). Results were consistent when compared against the population cohort.

By procedure, the 1-year AKI risk was 2.7% after RYGB and 2.4% after SG vs 2.5% in the overweight/obesity cohort and 1.1% in the population cohort. At 10 years, the risk for incident nephrolithiasis was 3.6% after RYGB and 1.2% after SG vs 2.4% and 1.3% in the overweight/obese and population cohorts, respectively. KFRT risk at 10 years was 0.2% after RYGB and 1.6% after SG vs 0.4% and 0.1% in the overweight/obesity and population cohorts, respectively. 

“The increased short-term risk of AKI and nephrolithiasis was expected, given the physiological changes after bariatric surgery, but the long-term reduction in CKD and KFRT was both encouraging and clinically important,” said study investigator Christian Goul Sørensen, MD, Department of Clinical Epidemiology, Department of Clinical Medicine, Aarhus University and Aarhus University Hospital, Aarhus, Denmark. “It was also noteworthy that the results were consistent not only in the obesity-matched comparison cohort but also in the cohort matched solely on age and sex, which further strengthens the validity of our findings.”

RYGB and SG are known to help mitigate obesity-associated complications, such as hypertension, hyperlipidemia, and type 2 diabetes. Studies have suggested that there are improvements in eGFR after bariatric surgery. However, long-term evidence from routine clinical care has not been well studied. Furthermore, RYGB may lead to AKI due to a combination of preoperative, intraoperative, and postoperative factors.

“Obesity is a major driver of kidney disease, often in combination with comorbidities such as diabetes and hypertension,” Sorensen told GI & Hepatology News. “Patients and clinicians face complex decisions about surgery, and understanding both the short-term surgical risks and the long-term kidney benefits is crucial for informed counseling. As bariatric surgery becomes increasingly common worldwide, population-based evidence like this helps guide clinical practice and supports shared decision-making with patients.”

 

Consistent With Clinical Experience

Panduranga S. Rao, MD, professor of nephrology at the University of Michigan, Ann Arbor, Michigan, who was not involved in the study, called the results consistent with prior clinical experience. He highlighted the strong follow-up and detailed lab and comorbidity data, while noting that the decreasing use of RYGB may limit applicability going forward.

“However, one has to remain vigilant to the risk of nephrolithiasis in the patients who have undergone Roux-en-Y in the past,” he said.

The observation of decreasing risk for CKD with weight loss is particularly relevant, given the growing use of GLP-1s for weight loss, Rao added.

Srinivasan Beddhu, MD, professor of internal medicine and the scientific director of the Cardio-Renal & Metabolism Center at the University of Utah Health in Salt Lake City, said the large national cohort design and outcomes data offer further reassurance about the long-term kidney health effects of bariatric surgery.

“The message that the risks of AKI and nephrolithiasis are outweighed by the long-term kidney protective effects of bariatric surgery is important,” said Beddhu.

Alexander Chang, MD, associate professor and a practicing nephrologist at the Geisinger Health System in Danville, Pennsylvania, noted that the study provided more evidence about RYGB-associated kidney stone risk via fat malabsorption, which raises the levels of fatty acids that bind dietary calcium.

“Calcium normally precipitates with dietary oxalate, and thus, there can be an increase in urinary oxalate,” Chang explained. “There did not appear to be increased risk of nephrolithiasis with sleeve gastrectomy, consistent with other studies.

“This study emphasizes the importance of multidisciplinary care post-bariatric surgery to try to prevent complications such as kidney stones,” Chang added. “This can be tricky but requires trying different strategies to increase fluid intake and calcium citrate supplements with meals.”

The study was partly funded by a grant from the Novo Nordisk Foundation and the Independent Research Fund Denmark. One author reported receiving a speaking fee support from Novo Nordisk for conference attendance. The other authors declared no competing interests. Sørensen, Rao, Beddhu, and Chang had no financial disclosures.

Studies have suggested that there are improvements in eGFR after bariatric surgery. However, long-term evidence from routine clinical care has not been well studied. Furthermore, RYGB may lead to AKI due to a combination of preoperative, intraoperative, and postoperative factors.

“Obesity is a major driver of kidney disease, often in combination with comorbidities such as diabetes and hypertension,” Sorensen told GI & Hepatology News. “Patients and clinicians face complex decisions about surgery, and understanding both the short-term surgical risks and the long-term kidney benefits is crucial for informed counseling. As bariatric surgery becomes increasingly common worldwide, population-based evidence like this helps guide clinical practice and supports shared decision-making with patients.”

 

Consistent With Clinical Experience

Panduranga S. Rao, MD, professor of nephrology at the University of Michigan, Ann Arbor, Michigan, who was not involved in the study, called the results consistent with prior clinical experience. He highlighted the strong follow-up and detailed lab and comorbidity data, while noting that the decreasing use of RYGB may limit applicability going forward.

“However, one has to remain vigilant to the risk of nephrolithiasis in the patients who have undergone Roux-en-Y in the past,” he said.

The observation of decreasing risk for CKD with weight loss is particularly relevant, given the growing use of GLP-1s for weight loss, Rao added.

Srinivasan Beddhu, MD, professor of internal medicine and the scientific director of the Cardio-Renal & Metabolism Center at the University of Utah Health in Salt Lake City, said the large national cohort design and outcomes data offer further reassurance about the long-term kidney health effects of bariatric surgery.

“The message that the risks of AKI and nephrolithiasis are outweighed by the long-term kidney protective effects of bariatric surgery is important,” said Beddhu.

Alexander Chang, MD, associate professor and a practicing nephrologist at the Geisinger Health System in Danville, Pennsylvania, noted that the study provided more evidence about RYGB-associated kidney stone risk via fat malabsorption, which raises the levels of fatty acids that bind dietary calcium.

“Calcium normally precipitates with dietary oxalate, and thus, there can be an increase in urinary oxalate,” Chang explained. “There did not appear to be increased risk of nephrolithiasis with sleeve gastrectomy, consistent with other studies.

“This study emphasizes the importance of multidisciplinary care post-bariatric surgery to try to prevent complications such as kidney stones,” Chang added. “This can be tricky but requires trying different strategies to increase fluid intake and calcium citrate supplements with meals.”

The study was partly funded by a grant from the Novo Nordisk Foundation and the Independent Research Fund Denmark. One author reported receiving a speaking fee support from Novo Nordisk for conference attendance. The other authors declared no competing interests. Sørensen, Rao, Beddhu, and Chang had no financial disclosures.

Bariatric surgery was associated with higher short-term risks for acute kidney injury (AKI) and nephrolithiasis but lower long-term risks for chronic kidney disease (CKD) and kidney failure with replacement therapy (KFRT), according to a population-based study in Denmark.

Writing in BMC Nephrology, researchers reported patients with bariatric surgery had an increased 1-year risk for AKI and 10-year risk for nephrolithiasis, alongside a decreased 10-year risk for CKD (stages G3-5) and KFRT, compared with matched patients diagnosed with overweight/obesity who did not undergo surgery.

 

A Closer Look

Using national registry data, the team identified all adults who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between January 1, 2006, and December 31, 2018. Each patient was age- and sex-matched (1:5) to patients with hospital-diagnosed overweight/obesity without bariatric surgery. Researchers also compared results against a population cohort matched solely by age and sex. Outcomes included cumulative risks for AKI, nephrolithiasis, CKD (G3-G5), and KFRT.

The cohort comprised 18,827 surgical patients (17,200 RYGB and 1627 SG) and 94,135 matched comparators. Median age was 41 years, 76% were women, and the median follow-up was 8.1 years. At baseline, the median estimated glomerular filtration rate (eGFR) was comparable (103 mL/min/1.73 m2) between both surgery and overweight/obesity control groups, as were A1c levels. There were fewer comorbidities in the population cohort matched only by age and sex than in the overweight/obesity comparison cohort.

Using multivariable Cox regression analyses, the researchers found the 1-year risk for AKI following bariatric surgery was 2.7%. At 10 years, risks were 3.5% for nephrolithiasis, 0.4% for CKD, and 0.2% for KFRT.

Adjusted hazard ratios (HRs) after bariatric surgery vs without bariatric surgery were higher for AKI (HR, 1.63) and nephrolithiasis (HR, 1.73) and lower for CKD (HR, 0.41) and KFRT (HR, 0.63). Results were consistent when compared against the population cohort.

By procedure, the 1-year AKI risk was 2.7% after RYGB and 2.4% after SG vs 2.5% in the overweight/obesity cohort and 1.1% in the population cohort. At 10 years, the risk for incident nephrolithiasis was 3.6% after RYGB and 1.2% after SG vs 2.4% and 1.3% in the overweight/obese and population cohorts, respectively. KFRT risk at 10 years was 0.2% after RYGB and 1.6% after SG vs 0.4% and 0.1% in the overweight/obesity and population cohorts, respectively. 

“The increased short-term risk of AKI and nephrolithiasis was expected, given the physiological changes after bariatric surgery, but the long-term reduction in CKD and KFRT was both encouraging and clinically important,” said study investigator Christian Goul Sørensen, MD, Department of Clinical Epidemiology, Department of Clinical Medicine, Aarhus University and Aarhus University Hospital, Aarhus, Denmark. “It was also noteworthy that the results were consistent not only in the obesity-matched comparison cohort but also in the cohort matched solely on age and sex, which further strengthens the validity of our findings.”
