Herpes to the rescue

Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?

Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.

Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.

During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
 

A breath of not-so-fresh air

There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.

As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.

The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.

Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?
 

We’re dying to try composting ... with humans, that is

We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.

There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”

Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.

California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.

We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
 

That’ll be one pandemic with extra distress. Hold the goals

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

Research on psoriatic arthritis (PsA) published over the past month has highlighted the effect of disease on patients and provided insights into clinical management. Because of the heterogeneous nature of PsA, assessing disease activity is difficult. A blood biomarker for disease activity would be useful. C-reactive protein (CRP) is a commonly used and well-established marker of inflammation in general. However, CRP does not reflect PsA disease activity itself. In a cross-sectional study, Gialouri and colleagues evaluated the association between CRP and PsA disease activity. CRP status (CRP  ≤  0.5 mg/dL [normal] and CRP > 0.5  mg/dL [increased]) was not associated with any of the clinical disease activity (clinical Disease Activity Index for Psoriatic Arthritis [cDAPSA] or minimal disease activity [MDA]) or patient-reported outcomes measures (Patient Global, Patient Pain, Health Assessment Questionnaire-Disability Index [HAQ-DI] or EuroQol [EQ-5D]). Among patients with normal CRP levels, a substantial proportion (45.9%) were not in MDA (thus, an indicator of active disease) while 76.7% of patients with elevated CRP were not in MDA. Therefore, an elevated CRP may indicate active PsA, but a normal CRP is not a reliable indicator of disease state in PsA.

Gender differences in PsA are increasingly being recognized as important. In a real-world survey of 2270 PsA patients (1047 women) from Europe and the United States, Gossec and colleagues demonstrated that, despite similar disease duration, disease presentation, and biologic use, women had worse quality-of-life, disability, and physical functioning scores, a greater degree of work activity impairment, and higher pain and fatigue scores compared with men. Thus, it is increasingly clear that PsA affects women differently from men. Interventions for the holistic management of PsA should be tailored according to the patient's gender for optimal outcomes.

Despite major advances in the treatment of adult PsA, the treatment options for children with PsA (juvenile PsA [JPsA]) are limited. Anti–tumor necrosis factor (TNF) agents are the only currently approved advanced therapy. Brunner and colleagues conducted a treatment-withdrawal, phase 3 study including 86 biologic-naive patients with active enthesitis-related arthritis (n = 52) or JPsA (n = 34) who were randomly assigned to receive secukinumab or placebo.

This study demonstrated that, compared with placebo, secukinumab was associated with a significant delay in disease flare and a higher proportion of patients achieving juvenile idiopathic arthritis American College of Rheumatology 30 response at week 104. This study provides evidence that secukinumab, a safe and effective therapy used in adult psoriatic disease, may provide similar benefits in JPsA, especially in patients who either have not responded to or have contraindications to treatment with anti-TNF agents.

Finally, because skin disease predates joint disease in almost 90% of PsA patients, identifying predictors for the development of joint disease is of considerable interest. It is hoped that identifying such predictors will help dermatologists and primary care physicians stratify management such that those at higher risk are carefully followed up for early diagnosis or even preventive therapy.

To identify such predictors, Ogdie and colleagues conducted a prospective study of 1489 patients with psoriasis and no prior diagnosis of PsA from the CorEvitas Psoriasis registry. They demonstrated that 10% of patients with psoriasis developed PsA after 2 years. Psoriasis Epidemiology Screening Tool (PEST, a brief screening questionnaire for PsA) and body mass index (BMI) were important factors predicting the development of PsA. Although the incidence of PsA in this cohort is higher than that reported from other studies, the study indicates that PEST and BMI should be important factors that predict PsA and should be variables in any prediction model.

As always, several provocative publications on colorectal cancer (CRC) have found their way into the medical literature. I will be discussing two of these in my Clinical Edge Journal Scan commentary for the month of October.

The first article, by Kennecke and colleagues, examines the role of neoadjuvant chemotherapy for early rectal cancer. We have been inundated with data showing that organ preservation is achievable in cases of node-positive rectal cancer with neoadjuvant chemoradiotherapy and chemotherapy (total neoadjuvant treatment [TNT] approach). As such, it stands to reason that organ preservation should also be achievable in cases of early, node-negative rectal cancer.

NEO was a single-arm, phase 2 trial examining the role of neoadjuvant chemotherapy only in early rectal cancer. In it, 58 patients with clinical T1-T3ab N0 low-to-mid rectal adenocarcinoma (proficient mismatch repair status) eligible for endoscopic resection were treated with 3 months of mFOLFOX6 (5-fluorouracil, leucovorin, and oxaliplatin) or CAPEOX (capecitabine and oxaliplatin). Those with evidence of tumor regression proceeded to transanal resection.

The primary endpoint was a protocol-specified organ preservation rate, defined as the proportion of patients with tumor downstaging to ypT0/T1 N0/X and who avoided radical surgery. Thirty-three (33) of the 58 patients were successfully downstaged, resulting in a protocol-specified organ preservation rate of 57% (90% CI 45-68). Of note, this treatment had no radiation at all and only used chemotherapy. Of the remaining 23 patients, 13 declined total mesorectal excision (TME) and went into observation. Of the 10 patients who underwent TME, seven had no histopathologic evidence of residual disease. The 1- and 2-year locoregional relapse-free survival rates were 98% (95% CI 86-100) and 90% (95% CI 58-98), respectively, and there were no metastatic recurrences or deaths. Although this is a small study, the results are enormously encouraging, suggesting that organ preservation not only can be achieved in early-stage rectal cancer, but also can be accomplished using only chemotherapy, further reducing morbidity to patients.

The second study I want to discuss was conducted by Ciardiello and colleagues and concerns the KRAS^G12C mutation in colorectal cancer. This mutation is targetable in lung cancer and has led to the approval of sotorasib for the treatment of advanced KRAS^G12C non–small-cell lung cancer . Unfortunately, previous studies of these inhibitors in advanced KRAS^G12C colorectal cancer have yielded disappointing results.

This study looked retrospectively at 6952 cases of metastatic colorectal cancer across Italy. A total of 256 cases (3.7%) demonstrated the KRAS^G12C mutation. Of those, 111 met inclusion criteria and were included in the analysis. Of note, this mutation was associated with a poor response to first-line chemotherapy (38.7%), with a median progression-free survival of 9 months (95% CI 7.5-10.5 months). Median overall survival was 21 months (95% CI 17.4-24.6 months). There was little difference between first-line oxaliplatin-containing regimens compared with those containing irinotecan. Triplet therapy (folinic acid, fluorouracil, oxaliplatin, and irinotecan; FOLFOXIRI) was associated with an objective response rate of 56.3% with a progression-free survival of 13 months and median overall survival of 32 months, suggesting that triplet therapy might be a better approach for these patients when they are identified. This study is important because it corroborates and builds upon data reported in smaller studies demonstrating the general resistance of KRAS^G12C metastatic colorectal cancer to chemotherapeutic treatments.

The primary endpoint was a protocol-specified organ preservation rate, defined as the proportion of patients with tumor downstaging to ypT0/T1 N0/X and who avoided radical surgery. Thirty-three (33) of the 58 patients were successfully downstaged, resulting in a protocol-specified organ preservation rate of 57% (90% CI 45-68). Of note, this treatment had no radiation at all and only used chemotherapy. Of the remaining 23 patients, 13 declined total mesorectal excision (TME) and went into observation. Of the 10 patients who underwent TME, seven had no histopathologic evidence of residual disease. The 1- and 2-year locoregional relapse-free survival rates were 98% (95% CI 86-100) and 90% (95% CI 58-98), respectively, and there were no metastatic recurrences or deaths. Although this is a small study, the results are enormously encouraging, suggesting that organ preservation not only can be achieved in early-stage rectal cancer, but also can be accomplished using only chemotherapy, further reducing morbidity to patients.

The second study I want to discuss was conducted by Ciardiello and colleagues and concerns the KRAS^G12C mutation in colorectal cancer. This mutation is targetable in lung cancer and has led to the approval of sotorasib for the treatment of advanced KRAS^G12C non–small-cell lung cancer . Unfortunately, previous studies of these inhibitors in advanced KRAS^G12C colorectal cancer have yielded disappointing results.

This study looked retrospectively at 6952 cases of metastatic colorectal cancer across Italy. A total of 256 cases (3.7%) demonstrated the KRAS^G12C mutation. Of those, 111 met inclusion criteria and were included in the analysis. Of note, this mutation was associated with a poor response to first-line chemotherapy (38.7%), with a median progression-free survival of 9 months (95% CI 7.5-10.5 months). Median overall survival was 21 months (95% CI 17.4-24.6 months). There was little difference between first-line oxaliplatin-containing regimens compared with those containing irinotecan. Triplet therapy (folinic acid, fluorouracil, oxaliplatin, and irinotecan; FOLFOXIRI) was associated with an objective response rate of 56.3% with a progression-free survival of 13 months and median overall survival of 32 months, suggesting that triplet therapy might be a better approach for these patients when they are identified. This study is important because it corroborates and builds upon data reported in smaller studies demonstrating the general resistance of KRAS^G12C metastatic colorectal cancer to chemotherapeutic treatments.

As always, several provocative publications on colorectal cancer (CRC) have found their way into the medical literature. I will be discussing two of these in my Clinical Edge Journal Scan commentary for the month of October.

The first article, by Kennecke and colleagues, examines the role of neoadjuvant chemotherapy for early rectal cancer. We have been inundated with data showing that organ preservation is achievable in cases of node-positive rectal cancer with neoadjuvant chemoradiotherapy and chemotherapy (total neoadjuvant treatment [TNT] approach). As such, it stands to reason that organ preservation should also be achievable in cases of early, node-negative rectal cancer.

NEO was a single-arm, phase 2 trial examining the role of neoadjuvant chemotherapy only in early rectal cancer. In it, 58 patients with clinical T1-T3ab N0 low-to-mid rectal adenocarcinoma (proficient mismatch repair status) eligible for endoscopic resection were treated with 3 months of mFOLFOX6 (5-fluorouracil, leucovorin, and oxaliplatin) or CAPEOX (capecitabine and oxaliplatin).

Interleukin (IL)–6 is known to be of great importance in the pathogenesis of rheumatoid arthritis (RA) owing to its role in the inflammatory response. Current IL-6-directed therapies in RA, namely sarilumab and tocilizumab, target the receptor. In a double-blind randomized controlled trial with both placebo and active comparators, Smolen and colleagues evaluated the efficacy of olokizumab, which directly binds and inhibits the activity of IL-6, in combination with methotrexate, in the treatment of people with RA. Patients were treated with methotrexate alone or in combination with adalimumab or olokizumab, and clinical outcomes were evaluated after 12 weeks, a relatively short time frame. Olokizumab was noninferior to adalimumab in terms of the proportion of patients achieving an American College of Rheumatology 20 response, with similar rates of serious adverse events, the most common of which was infection. Though this study included patients from across the globe, the percentage of Black and Asian patients was relatively low and thus may affect the generalizability of this study to a US population; the numbers of patients in each group was also relatively small. These results certainly warrant larger-scale and longer studies to evaluate olokizumab's efficacy.

For those patients with RA who achieve sustained disease remission, the question of medication tapering has been raised as a possible strategy for minimizing risks for therapy. Using insurance database information, Birkner and colleagues performed a prospective cohort study of over 400 patients in Germany. Using shared decision-making between patients and their rheumatologists, two groups of patients were followed: 237 people who elected to remain on therapy and 200 who decided to taper medication. Of note, similar proportions of patients in both groups were taking conventional and biologic disease-modifying antirheumatic drug (DMARD) monotherapy, but more patients in the tapering group were taking a combination therapy with both. Flares and loss of remission were more common in the continuation group, a difference that did not persist after adjusting for patient risk characteristics. Overall, results from this "real-world" study were consistent with prior studies and support the possibility of tapering with flare in a subset of patients. Although the authors address the potential for selection bias in terms of patients "assigned" to each group, this can also be viewed as part of the shared decision-making in determining the appropriateness of tapering therapy in individual patients.

Because people receiving rituximab have experienced more severe COVID-19, studies aimed at enhancing the protection of these patients are of current interest. Of note, in a follow-up to a prior observational study by van der Togt and colleagues on the response to COVID-19 vaccines in people with RA being treated with rituximab, they looked at responses to the third (booster) dose of the COVID-19 vaccine. Only about 20% of patients treated with rituximab developed a humoral response to a third vaccine dose, as defined by immunoglobulins (Ig; total, IgG, and IgM) against SARS-CoV-2. Patients treated with 200 mg rituximab had a higher response rate than did those treated with 500 mg or 1000 mg, though this difference was not statistically significant. The study lacked a control arm of people being treated with other DMARD and also did not measure B-cell counts, COVID-19, or outcomes. Reassuringly, those patients who did have a positive humoral response to the first two vaccine doses tended to maintain a humoral response to the third, regardless of rituximab dose or timing.

The level of remission in patients with remitting inflammatory bowel disease (IBD) appears to play a major role in whether they will relapse after treatment when biologic therapies are discontinued, according to a new prospective study.

Patients with complete endoscopic healing have half the rate of relapse after withdrawal of anti-tumor necrosis factor alpha (anti-TNF) treatment than those with only partial healing, according to a study published online in Clinical Gastroenterology and Hepatology.

“Applying strict criteria for endoscopic healing and mesalamine treatment ... may lower the risk of relapse after withdrawal of anti-TNF treatment,” write Bas Oldenburg, MD, PhD, a professor at University Medical Center Utrecht, the Netherlands, and colleagues in their analysis of 81 patients.

De-escalation of anti-TNF treatment in IBD patients in remission has the potential to “reduce side effects, including risks of serious infections and malignancies, decrease health care expenditures, and meet patients’ preferences,” they note.

However, withdrawal of the drugs increases the risk of relapse by 30%-45% at 12 months. When patients relapse, reintroduction of anti-TNF therapy returns over 80% to remission.

Although no consensus exists on how to select patients for therapy de-escalation, evidence suggests that persistent inflammation affects outcomes and that the “depth” of endoscopic healing is a key indicator, the authors note.
 

Study details

To further the knowledge base, they conducted a prospective study of patients in remission to determine the relapse rate following de-escalation of anti-TNF therapy; evaluate relapse factors, including degree of endoscopic healing; and assess outcomes after reintroduction of anti-TNF therapy.

The study was limited to adult patients with IBD with at least 6 months of corticosteroid-free clinical remission, confirmed baseline clinical remission and endoscopic healing, no current hospitalization, and no pregnancy.

The patients underwent elective discontinuation of anti-TNF therapy between 2018 and 2020. The recommended protocol was to measure C-reactive protein (CRP) and fecal calprotectin at 3, 6, 12, and 24 months and to perform endoscopy at 12 months.

Patients also completed questionnaires at baseline and at 3, 6, 12, and 24 months. The authors selected the patient–Harvey-Bradshaw Index for patients with Crohn’s disease and the patient–Simple Clinical Colitis Activity Index for patients with ulcerative colitis and unclassified IBD, as well as the short IBD Quality of Life measure.

Of the 81 patients from 13 centers who took part, 51% had Crohn’s disease. The median duration of remission at baseline was 3.5 years, and the median disease duration was 9.1 years.

All patients had evidence of endoscopic healing, and 88% met the strict criteria for complete endoscopic healing. In 34%, trough levels of anti-TNF treatments were judged to be subtherapeutic.

After withdrawal of the drugs, 25.9% of patients continued on immunomodulators.

Over a median follow-up of 2 years, 49% of patients relapsed, which was confirmed via endoscopy, fecal calprotectin, or CRP in 83% of cases and inferred from treatment escalation for clinical flare in 17%. Rates of relapse were comparable between patients with Crohn’s disease and ulcerative colitis or unclassified IBD and between those discontinuing adalimumab and those stopping infliximab.
 

Better healing, better outcomes

However, analysis showed that partial endoscopic healing was independently associated with a higher risk of relapse, at an adjusted hazard ratio versus complete endoscopic healing of 3.28.

At 12 months, 70% of patients with partial endoscopic healing had relapsed versus 35% of those with complete endoscopic healing.

Treatment with the anti-inflammatory agent mesalamine (multiple brands) was independently associated with a reduced risk of relapse, at an adjusted hazard ratio of 0.08. No other potential predictors of relapse were identified.

Of the patients who relapsed, 75% restarted anti-TNF treatment, and the majority (87%) were restarted on the same agent at a median of 0.9 years since its withdrawal and a median of 24 days since the onset of relapse.

Clinical remission was achieved at 3 months in 73% of patients who restarted anti-TNF therapy, which was found to restore quality of life and well-being in relapsed patients, the authors report.
 

Reluctance remains

Stephen B. Hanauer, MD, professor of medicine (gastroenterology and hepatology) at Northwestern University Feinberg School of Medicine, Chicago, said the findings “reinforce the benefits of the maintenance versus the withdrawal of therapy” and “the deeper the remission” the more likely it is to be sustained.

The 35% relapse rate at 12 months, even in patients with compete endoscopic healing, indicates that treatment should be maintained, Dr. Hanauer said.

“What is also relevant, but was not evaluated, is the additional endpoint of histologic healing, which is likely to sustain remissions even longer,” he added.

Nevertheless, Dr. Hanauer said, the “observed relapse rate is important to discuss in shared decision-making with patients.”

The findings are interesting, but the study didn’t follow the patients for long enough to understand why 35% of those with complete endoscopic healing relapsed, Miguel Regueiro, MD, chair of the Cleveland Clinic’s Digestive Disease & Surgery Institute, told this news organization.

“Are there predictors, factors, or other treatments that could be used to reduce that 35% risk of relapse further?” he questioned.

Although the study didn’t clear up that question for Dr. Regueiro, he found it compelling that mesalamine continuation resulted in higher rates of sustained remission after anti-TNF withdrawal among patients with ulcerative colitis.

Dr. Regueiro said that he will not begin recommending withdrawal of advanced therapies, including anti-TNF drugs, in patients who have achieved a stable remission.

“We have not yet found the cure for IBD, and my concern is that patients may relapse with more severe disease than previously and that recurrence of inflammation could have potential risks for complications,” he said.

“Nonetheless, this study is intriguing and important, and at least prompts the discussion of withdrawing therapy in those who have achieved a deep endoscopic remission for a sustained period of time,” Dr. Regueiro added.

The study received support from the Dutch Health Insurance Innovation Fund.

However, analysis showed that partial endoscopic healing was independently associated with a higher risk of relapse, at an adjusted hazard ratio versus complete endoscopic healing of 3.28.

At 12 months, 70% of patients with partial endoscopic healing had relapsed versus 35% of those with complete endoscopic healing.

Treatment with the anti-inflammatory agent mesalamine (multiple brands) was independently associated with a reduced risk of relapse, at an adjusted hazard ratio of 0.08. No other potential predictors of relapse were identified.

Of the patients who relapsed, 75% restarted anti-TNF treatment, and the majority (87%) were restarted on the same agent at a median of 0.9 years since its withdrawal and a median of 24 days since the onset of relapse.

Clinical remission was achieved at 3 months in 73% of patients who restarted anti-TNF therapy, which was found to restore quality of life and well-being in relapsed patients, the authors report.
 

Reluctance remains

Stephen B. Hanauer, MD, professor of medicine (gastroenterology and hepatology) at Northwestern University Feinberg School of Medicine, Chicago, said the findings “reinforce the benefits of the maintenance versus the withdrawal of therapy” and “the deeper the remission” the more likely it is to be sustained.

The 35% relapse rate at 12 months, even in patients with compete endoscopic healing, indicates that treatment should be maintained, Dr. Hanauer said.

“What is also relevant, but was not evaluated, is the additional endpoint of histologic healing, which is likely to sustain remissions even longer,” he added.

Nevertheless, Dr. Hanauer said, the “observed relapse rate is important to discuss in shared decision-making with patients.”

The findings are interesting, but the study didn’t follow the patients for long enough to understand why 35% of those with complete endoscopic healing relapsed, Miguel Regueiro, MD, chair of the Cleveland Clinic’s Digestive Disease & Surgery Institute, told this news organization.

“Are there predictors, factors, or other treatments that could be used to reduce that 35% risk of relapse further?” he questioned.

Although the study didn’t clear up that question for Dr. Regueiro, he found it compelling that mesalamine continuation resulted in higher rates of sustained remission after anti-TNF withdrawal among patients with ulcerative colitis.

Dr. Regueiro said that he will not begin recommending withdrawal of advanced therapies, including anti-TNF drugs, in patients who have achieved a stable remission.

“We have not yet found the cure for IBD, and my concern is that patients may relapse with more severe disease than previously and that recurrence of inflammation could have potential risks for complications,” he said.

“Nonetheless, this study is intriguing and important, and at least prompts the discussion of withdrawing therapy in those who have achieved a deep endoscopic remission for a sustained period of time,” Dr. Regueiro added.

The study received support from the Dutch Health Insurance Innovation Fund.

Patients with gastrointestinal esophageal reflux disease (GERD) have more than three times the risk of developing nontuberculous mycobacterial pulmonary disease (NTM-PD), compared with those without GERD, according to a population-based retrospective cohort study.

“GERD is a common comorbidity of nontuberculous mycobacterial pulmonary disease [but] whether GERD is associated with an increased risk of developing NTM-PD is unknown,” Hayoung Choi, MD, PhD, Hallym University, Seoul, Republic of Korea, and colleagues reported.

“Our study showed the relation between GERD and NTM infections, but preventing NTM is not simple,” Dr. Choi added in an email. “What needs to be understood is that GERD increases health care utilization in patients with NTM pulmonary disease; hence, clinicians who treat patients with NTM pulmonary disease need to be aware of the burden of GERD and treat the gastrointestinal illness simultaneously,” he added.

The study was published online in the journal CHEST.
 

Sample cohort

Data from the Korean National Health Insurance Service-National Sample Cohort between 2002 and 2015 were used to assess the impact of GERD on NTM-PD. The incidence and risk of NTM-PD were compared between 17,424 patients with GERD and 69,000 patients without GERD in a matched cohort. GERD was defined as patients having received more than 3 months of proton pump inhibitors (PPIs).

During a median follow-up of 5.1 years, the age- and sex-adjusted incidence of NTM-PD was significantly higher in the GERD cohort, at a rate of 34.8/100,000 person-years, than in the matched cohort, at a rate of only 10.5/100,000 person-years (P < .001), the authors reported.

As for risk factors for NTM-PD, being 60 years of age and older was associated with a 3.5-times higher risk of NTM-PD at an adjusted hazard ratio of 3.57 (95% confidence interval, 1.58-8.07), while bronchiectasis was associated with over an 18-times higher risk of NTM-PD in the GERD cohort at an adjusted HR of 18.69 (95% CI, 6.68-552.28). Those with GERD who developed NTM-PD had higher all-cause and respiratory disease–related emergency department visits or hospitalizations compared with patients with GERD who did not develop NTM-PD (P = .011), the investigators noted.

As the authors pointed out, the incidence of NTM-PD in the Korean population ranged from 6 to 19 cases/100,000 between 2008 and 2016; thus, the burden of incident NTM-PD associated with GERD appears to be considerable. As Dr. Choi explained, a combination of three factors influenced the development of NTM infections. The first is environmental, from water source, climate, or region; the second is patient influences, including such factors as immunodeficiency and comorbidities (including bronchiectasis); and the third is microbiological factors, including various NTM species.

Bile aspirating into the lung during GERD may be another possible pathway, as the authors suggested. Even if acid secretion is suppressed by PPI treatment in patients with GERD, NTM-PD may be induced or aggravated through mechanisms such as bile reflux. The fact that patients over the age of 60 were more prone to develop NTM-PD suggests that a decrease in gastric emptying and increased micro-aspiration or reflux associated with impaired swallowing (which are more common in elderly patients) may also be at play.

“Bronchiectasis is also a very well known risk factor for NTM pulmonary disease,” Dr. Choi emphasized. Thus, he recommends clinicians carefully observe clinical, radiological, and microbiological changes to detect NTM pulmonary disease when managing patients with bronchiectasis.

“The results of the present study have several potential clinical implications,” Dr. Choi and colleagues observed. First, NTM-PD should be suspected when new-onset worsening of respiratory symptoms develops during regular follow-up in patients with GERD. Second, because results indicate that older age and bronchiectasis significantly increase the risk of NTM-PD, “more active strategies (e.g., screening of symptoms and regular chest x-rays)” might be helpful in patients with GERD and these risk factors, the authors suggested. Because patients with GERD who developed NTM-PD had more respiratory disease–related ED visits and hospitalizations than those who did not develop NTM-PD, when GERD and NTM-PD are combined, clinicians should focus on the variations of respiratory symptoms, they suggested.

The authors cautioned, however, that because the study was one in a Korean population, studies in other countries and different ethnicities are needed before findings can be generalized.

More common than TB

Asked to comment on the findings, NTM-PD expert Theodore Marras, MD, clinician investigator, Krembil Research Institute, Toronto, noted that non-TB M-PD is about 10 times more common than TB and that could be an underestimate as there have been very large increases in the incidence of NTM-PD in recent years. “It’s an environmental germ – it’s in our water – and certain people are particularly susceptible to it, typically older age women who have underlying bronchiectasis,” Dr. Marras told this news organization. “And while there are ethnic differences in incidence rates between East Asian people and Black African people, immigration is not the main driver for the increase as far as we can tell,” he said.

He personally treats a lot of NTM-PD and he also believes that GERD is an important risk factor for all types of lung infections including NTM lung disease. “So without a doubt, I believe that GERD should be treated in patients with NTM-PD,” Dr. Marras emphasized. The big question is how to treat GERD, as there may be concerns with acid-suppressive agents such as proton pump inhibitors that “the reflux that comes back up may harbor more germs in it and if that reflux comes up high enough, we are at risk of aspirating some of that fluid into our lungs, especially when we’re asleep,” he said.

Some experts therefore argue in favor of using motility agents instead of PPIs. However, if Dr. Marras has a patient with heartburn, “you have to treat it,” he stressed. Similarly, if a patient has evidence of esophageal erosions, physicians need to treat those as well. However, if neither feature is present, “I tend to like the motility agents preferentially or use them in combination with a PPI,” Dr. Marras said.

Dr. Marras also thinks the study is encouraging physicians involved in treating these patients to think about controlling GERD both when they are treating patients and after they are treated to try to reduce recurrence.

The authors had no financial disclosures to make. Dr. Marras has given several talks on NTM lung disease, one sponsored by AstraZeneca and the other by Novartis.

The Safer Opioid Supply (SOS) Program near Toronto, Canada, appears to be a safe and effective harm-reduction initiative, according to new data.

An analysis indicates that the program is associated with a reduction in emergency department visits, hospitalizations, and overall health care costs. In addition, there were no opioid-related deaths among participants who were at high risk of overdose.

“Not only did hospital engagements decline immediately after starting SOS programs, but also the risk of overdose did not change, and there were no opioid-related deaths in the 1-year follow-up,” study author Tara Gomes, PhD, an assistant professor of health policy, management, and evaluation at the University of Toronto and a scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital in Toronto, said in an interview.

Dr. Gomes is the lead principal investigator of the Ontario Drug Policy Research Network, a collaboration between researchers and drug policy decision-makers in the province.

“These changes were not seen in a group of similar individuals who lived in the same city – so were exposed to the same illicit drug supply – but who were not part of this program, helping to reinforce that these changes are specific to SOS participation,” she said.

The study was published in the Canadian Medical Association Journal.
 

Hospital admissions declined

More than 29,000 opioid-related toxicity deaths occurred in Canada between 2016 and 2021, often as a result of high levels of fentanyl in the drug supply, according to the investigators. In response, SOS programs have been launched in several provinces, including the first formal SOS program at the London (Ont.) InterCommunity Health Centre. As part of the program, clients are prescribed pharmaceutical opioids as an alternative to the fentanyl-adulterated drug supply and are given health and social supports.

Dr. Gomes and colleagues conducted an interrupted time series analysis of residents in London, Ont., who had received a diagnosis of opioid use disorder and had had a health care encounter related to the diagnosis between January 2016 and March 2019. They followed 82 participants who entered the SOS program, as well as a comparison group of 303 people who were matched on the basis of demographic and clinical characteristics but who did not participate in the program.

The research team focused on the population’s numbers of emergency department visits, hospital admissions, infection rates, and health care costs. They used autoregressive integrated moving average models to evaluate the effect of starting the SOS program and to compare the population’s outcome rates in the year before and after entering the program.

For participants who entered the program, the rate of emergency department visits declined by about 14 visits per 100 people. In addition, hospital admissions declined by about 5 admissions per 100 people. Health care costs that weren’t related to primary care or outpatient medications declined by about $922 per person. The rate of hospital admission for infections remained about the same; the investigators observed a decline of about 1.6 infections per 100 people.

In the year after entry into the program, emergency department visits, hospital admissions, infection-related admissions, and total health care costs declined significantly among SOS clients, compared with the year before.

Conversely, there were no significant changes in any of the measured outcomes among the 303 people who didn’t participate in the program.
 

Medication costs increased

DR. Gomes and colleagues noted that the findings provide preliminary evidence that SOS programs can play a role in the harm-reduction options available to those who are at high risk of drug poisoning and overdose. At the same time, many questions remain.

For instance, although total health care costs declined among those enrolled in the program, the medication-related costs increased. About 34% of participants had HIV, 69.5% had hepatitis C virus infection, and 28% had infectious complications in the year before entering the program. This finding may indicate that the participants had serious medical complications resulting from their drug use and were able to seek health care services.

“We interpret that to be a positive finding, because of the very high prevalence of HIV and hepatitis C in the SOS clients. Treatments for HIV and hepatitis C are lifesaving but expensive,” said Dr. Gomes. “Therefore, these higher medication costs are likely reflective of improved access to treatments for these infections, which can greatly improve people’s health and quality of life but also save the health care system money over the longer term.”

DR. Gomes and colleagues are now beginning to evaluate other SOS programs across Ontario. They hope to better understand the various approaches that are available and determine which models can best support people who face high risks because of drug use.
 

A limited solution?

Commenting on the study, Andrew Ivsins, PhD, a postdoctoral fellow in social medicine at the University of British Columbia in Vancouver and a research scientist at the British Columbia Centre on Substance Abuse, said, “This is an important study and one of the first to show how safe supply can help by building connections to the health care system that didn’t exist previously.”

Dr. Ivsins, who wasn’t involved with this study, has researched safe supply programs around Vancouver. He and colleagues found that among participants in these programs, the use of illicit street-purchased drugs decreased, which led to improved health and wellness.

“Safe supply is fundamentally, at the most basic level, a response to the highly toxic drug supply and out-of-control poisoning crisis in North America,” he said. “It’s a contentious issue, but it makes so much sense that, if what’s killing people is highly toxic drugs, we need to find a way to provide an option that doesn’t kill them.”

“Up to now, safer supply has mostly been used to reduce harms, including mortality and morbidity, in persons using illicit opioids. But if we really want to lower the risk linked to heavy contamination of the unregulated drug supply, safer supply programs will have to be extended to all substances potentially sold illegally,” Marie-Eve Goyer, MD, an assistant professor of family medicine at the University of Montreal, said in an interview.

Dr. Goyer, who wasn’t involved with this study, has conducted research about substance replacement therapy in Quebec. She found that many provinces are now reporting on new potent designer benzodiazepines that are being used or that are contaminating fentanyl, which calls for a broader approach to address the drug overdose crisis.

“Let’s realize that safer supply prescription is a very medicalized (and limited) solution to an epidemic that is made of stigma, criminalization, and repressive public policies,” she said. “Without true changes in the law, we will continue to see our people dying every day.”

The study was funded by grants from the Ontario Ministry of Health and the Canadian Institutes of Health Research. Dr. Gomes has received grants to support the research of both groups, and other authors have received support or fees related to the London InterCommunity Health Centre. Dr. Ivsins and Dr. Goyer have disclosed no relevant financial relationships.

This finding may indicate that the participants had serious medical complications resulting from their drug use and were able to seek health care services.

“We interpret that to be a positive finding, because of the very high prevalence of HIV and hepatitis C in the SOS clients. Treatments for HIV and hepatitis C are lifesaving but expensive,” said Dr. Gomes. “Therefore, these higher medication costs are likely reflective of improved access to treatments for these infections, which can greatly improve people’s health and quality of life but also save the health care system money over the longer term.”

DR. Gomes and colleagues are now beginning to evaluate other SOS programs across Ontario. They hope to better understand the various approaches that are available and determine which models can best support people who face high risks because of drug use.
 

A limited solution?

Commenting on the study, Andrew Ivsins, PhD, a postdoctoral fellow in social medicine at the University of British Columbia in Vancouver and a research scientist at the British Columbia Centre on Substance Abuse, said, “This is an important study and one of the first to show how safe supply can help by building connections to the health care system that didn’t exist previously.”

Dr. Ivsins, who wasn’t involved with this study, has researched safe supply programs around Vancouver. He and colleagues found that among participants in these programs, the use of illicit street-purchased drugs decreased, which led to improved health and wellness.

“Safe supply is fundamentally, at the most basic level, a response to the highly toxic drug supply and out-of-control poisoning crisis in North America,” he said. “It’s a contentious issue, but it makes so much sense that, if what’s killing people is highly toxic drugs, we need to find a way to provide an option that doesn’t kill them.”

“Up to now, safer supply has mostly been used to reduce harms, including mortality and morbidity, in persons using illicit opioids. But if we really want to lower the risk linked to heavy contamination of the unregulated drug supply, safer supply programs will have to be extended to all substances potentially sold illegally,” Marie-Eve Goyer, MD, an assistant professor of family medicine at the University of Montreal, said in an interview.

Dr. Goyer, who wasn’t involved with this study, has conducted research about substance replacement therapy in Quebec. She found that many provinces are now reporting on new potent designer benzodiazepines that are being used or that are contaminating fentanyl, which calls for a broader approach to address the drug overdose crisis.

“Let’s realize that safer supply prescription is a very medicalized (and limited) solution to an epidemic that is made of stigma, criminalization, and repressive public policies,” she said. “Without true changes in the law, we will continue to see our people dying every day.”

The study was funded by grants from the Ontario Ministry of Health and the Canadian Institutes of Health Research. Dr. Gomes has received grants to support the research of both groups, and other authors have received support or fees related to the London InterCommunity Health Centre. Dr. Ivsins and Dr. Goyer have disclosed no relevant financial relationships.

The Safer Opioid Supply (SOS) Program near Toronto, Canada, appears to be a safe and effective harm-reduction initiative, according to new data.

An analysis indicates that the program is associated with a reduction in emergency department visits, hospitalizations, and overall health care costs. In addition, there were no opioid-related deaths among participants who were at high risk of overdose.

“Not only did hospital engagements decline immediately after starting SOS programs, but also the risk of overdose did not change, and there were no opioid-related deaths in the 1-year follow-up,” study author Tara Gomes, PhD, an assistant professor of health policy, management, and evaluation at the University of Toronto and a scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital in Toronto, said in an interview.

Dr. Gomes is the lead principal investigator of the Ontario Drug Policy Research Network, a collaboration between researchers and drug policy decision-makers in the province.

“These changes were not seen in a group of similar individuals who lived in the same city – so were exposed to the same illicit drug supply – but who were not part of this program, helping to reinforce that these changes are specific to SOS participation,” she said.

The study was published in the Canadian Medical Association Journal.
 

Hospital admissions declined

More than 29,000 opioid-related toxicity deaths occurred in Canada between 2016 and 2021, often as a result of high levels of fentanyl in the drug supply, according to the investigators. In response, SOS programs have been launched in several provinces, including the first formal SOS program at the London (Ont.) InterCommunity Health Centre. As part of the program, clients are prescribed pharmaceutical opioids as an alternative to the fentanyl-adulterated drug supply and are given health and social supports.

Dr. Gomes and colleagues conducted an interrupted time series analysis of residents in London, Ont., who had received a diagnosis of opioid use disorder and had had a health care encounter related to the diagnosis between January 2016 and March 2019. They followed 82 participants who entered the SOS program, as well as a comparison group of 303 people who were matched on the basis of demographic and clinical characteristics but who did not participate in the program.

The research team focused on the population’s numbers of emergency department visits, hospital admissions, infection rates, and health care costs. They used autoregressive integrated moving average models to evaluate the effect of starting the SOS program and to compare the population’s outcome rates in the year before and after entering the program.

For participants who entered the program, the rate of emergency department visits declined by about 14 visits per 100 people. In addition, hospital admissions declined by about 5 admissions per 100 people. Health care costs that weren’t related to primary care or outpatient medications declined by about $922 per person. The rate of hospital admission for infections remained about the same; the investigators observed a decline of about 1.6 infections per 100 people.

In the year after entry into the program, emergency department visits, hospital admissions, infection-related admissions, and total health care costs declined significantly among SOS clients, compared with the year before.

Conversely, there were no significant changes in any of the measured outcomes among the 303 people who didn’t participate in the program.
 

Medication costs increased

DR. Gomes and colleagues noted that the findings provide preliminary evidence that SOS programs can play a role in the harm-reduction options available to those who are at high risk of drug poisoning and overdose. At the same time, many questions remain.

For instance, although total health care costs declined among those enrolled in the program, the medication-related costs increased. About 34% of participants had HIV, 69.5% had hepatitis C virus infection, and 28% had infectious complications in the year before entering the program. This finding may indicate that the participants had serious medical complications resulting from their drug use and were able to seek health care services.

“We interpret that to be a positive finding, because of the very high prevalence of HIV and hepatitis C in the SOS clients. Treatments for HIV and hepatitis C are lifesaving but expensive,” said Dr. Gomes. “Therefore, these higher medication costs are likely reflective of improved access to treatments for these infections, which can greatly improve people’s health and quality of life but also save the health care system money over the longer term.”

DR. Gomes and colleagues are now beginning to evaluate other SOS programs across Ontario. They hope to better understand the various approaches that are available and determine which models can best support people who face high risks because of drug use.

Monkeypox cases are declining in the United States and the United Kingdom, but experts are urging the public to continue efforts to stanch the spread of the virus. Continued transmission of monkeypox provides more opportunities for the virus to mutate, according to Philip Johnson, PhD, assistant professor of biology at the University of Maryland, College Park, and colleagues.

“Just because a disease like monkeypox appears to be controllable does not mean it will stay controllable,” the authors wrote in a correspondence published in The Lancet.

When case numbers are lower – and therefore less of a public health concern – viral transmission chains can be longer without causing alarm, Dr. Johnson explained. “The more generations of transmission, the more opportunities there are for mutations to occur,” he told this news organization. While it is difficult to anticipate how mutations can affect a virus, these changes in genetic code could be advantageous to the virus, making it more transmissible from human to human and therefore much more difficult to control.

This applies to any virus. The large Ebola outbreak from 2013 to 2016 is an example; a retrospective analysis found that specific amino acid changes in the Ebola virus increased growth in human cells and may have made the virus more infectious. More recently, the Delta and Omicron variants of SARS-CoV-2 each contained mutations that were associated with higher transmissibility. A recent study suggested that monkeypox appears to be mutating faster than expected, though it is not clear if these genetic mutations have changed the virus’ behavior.

Zoonotic infections, or viruses that originate from nonhuman animals, at first are expected to be less adapted to people, but that can change over time. When a virus continues to jump from animals to humans – as monkeypox has done since it was first identified in humans in 1970 – chances are it will gain a mutation that allows it to spread more effectively between people, said Rachel Roper, PhD, a professor of microbiology and immunology at East Carolina University, Greenville, N.C. She was not involved with The Lancet article.

“We discounted monkeypox; we didn’t pay much attention to it because it had not been that big of a problem,” she said in an interview. “We think this virus has been circulating now since 2017 and we really just realized it in May.”

Although monkeypox received global attention this past summer, the outbreak is now receiving less news coverage, and the public’s attention may be waning. Furthermore, the U.S. Congress just dropped billions of dollars from a short-term spending bill that would have provided additional COVID-19 and monkeypox funding.

Although new cases are trending downward, now is not the time to take our foot off the gas, Dr. Johnson and colleagues warned. “The epidemic is far from over, and continued drive toward elimination is essential,” the authors wrote. Because the virus exists in rodent populations in areas of central and west Africa, it is not possible to eradicate monkeypox as we did smallpox; however, “we could, through vaccination, eliminate any significant human to human transmission,” Dr. Johnson said.

Dr. Johnson also urges a more proactive approach to combating emerging infectious diseases in the future. “We wrote this article to raise awareness about the importance of dedicating resources to controlling these diseases all the way down to ideally elimination in the countries where they develop, and not just waiting until [these diseases] reach wealthier countries,” he said.

Dr. Roper agrees that a more global perspective is needed in monitoring and controlling zoonotic disease, but resources are limited. “The problem is there are a whole bunch of virus groups and a whole bunch of viruses jumping into humans all the time,” she said. “We can’t predict which virus group is going to be the next one with a big hit. I worked on SARS-CoV-1 back in 2003 to 2009, and I would have predicted that a virus from some other group would have jumped into humans next, before COVID hit,” she added.

Dr. Johnson acknowledged that it is hard to know where to focus public health resources, considering the hundreds of thousands of zoonotic viruses that may exist. He thought the best approach was to target emerging diseases that already appear to have extended transmission chains, “not just things that are hopping from animals to humans and sputtering out and disappearing, but diseases that appear to have any sustained human to human transmission.”

Dr. Johnson and Dr. Roper report no relevant financial relationships.

Treatment of rheumatoid arthritis with olokizumab combined with methotrexate led to significantly more patients with improved signs and symptoms than did methotrexate plus placebo in circumstances where previous treatment with one or more tumor necrosis factor (TNF) inhibitors yielded inadequate responses, results from a phase 3 randomized trial show.

At the week 12 primary endpoint, 40.6% of patients receiving placebo had at least 20% improvement in American College of Rheumatology response criteria (ACR 20), compared with 60.9% of patients receiving olokizumab 64 mg every 2 weeks and 59.6% of patients receiving olokizumab 64 mg every 4 weeks (P <.01 for both comparisons), senior author Roy M. Fleischmann, MD, of the University of Texas Southwestern Medical Center in Dallas and colleagues reported in Annals of the Rheumatic Diseases.

Expert commentary

There are currently two biologics on the market that inhibit the IL-6 receptor, tocilizumab (Actemra), and sarilumab (Kevzara), but olokizumab is unique in that “it does not block the receptor. It binds directly to the cytokine,” noted Larry Moreland, MD, a professor of medicine and orthopedics in the division of rheumatology at the University of Colorado at Denver in Aurora, who was not involved in the study.

Tocilizumab and sarilumab had a similar clinical trial portfolio when they were studied in people who failed anti-TNF therapy, so this is the standard study a company would do prior to seeking approval, Dr. Moreland said.

“The fact that there is another IL-6 blocker that is showing promise means that there are more opportunities for researchers and clinicians to use these agents not only for rheumatoid arthritis but also hopefully study them in other diseases,” he said.

The CREDO 3 trial was sponsored by R-Pharm. Some of the authors are employees of R-Pharm. Dr. Fleischmann and some of his coauthors reported financial ties to R-Pharm and other pharmaceutical companies. Dr. Moreland reported having no relevant competing interests.
