WASHINGTON – Results from new analyses further fleshed out the potent effect by the investigational SGLT1&2 inhibitor sotagliflozin on major cardiovascular adverse events in patients with type 2 diabetes, chronic kidney disease, and at high risk for cardiovascular disease in the SCORED trial that randomized more than 10,000 patients.

In prespecified, secondary analyses of the SCORED results, treatment with sotagliflozin during a median of 16 months was linked to a significant 21% risk reduction relative to placebo for the combined incidence of total major adverse cardiovascular events (MACE), which included cardiovascular death, first and recurrent episodes of nonfatal MI, and nonfatal stroke among the 5,144 randomized patients who entered the trial with a history of cardiovascular disease (CVD), Deepak L. Bhatt, MD, said at the annual scientific sessions of the American College of Cardiology.

Among the 5,440 patients in the study who did not have a history of CVD (although they did have at least one major risk factor or at least two minor risk factors), treatment with sotagliflozin was linked to a significant 26% relative risk reduction in total MACE events.

Part of these overall MACE benefits resulted from similar improvements from sotagliflozin treatment on the individual outcomes of total nonfatal MI and total nonfatal strokes. Treatment with sotagliflozin cut these MIs by a significant 31% in patients with a history of CVD relative to patients who received placebo, and by a relative 34% in those without a CVD event in their history, a difference compared with placebo that fell short of significance, said Dr. Bhatt, professor of medicine at Harvard Medical School and executive director of interventional cardiovascular programs at Brigham and Women’s Health, both in Boston.

Treatment with sotagliflozin also cut total nonfatal strokes by 31% relative to placebo in patients with a history of CVD, and by a relative 38% in those without a CVD history. Both differences fell short of significance.
 

An early MACE benefit and a stroke benefit

“This stroke benefit has not been clearly seen” with any agent from the closely related sodium-glucose cotransport-2 (SGLT2) inhibitor class, and “the MACE benefit appeared very early,” within 3 months from the start of sotagliflozin treatment, “which may be because of the SGLT1 inhibition,” Dr. Bhatt said during his report.

The SGLT1 receptor is the primary mechanism cells in the gut use to absorb glucose and galactose in the human gastrointestinal tract, Dr. Bhatt explained, while the SGLT2 receptor appears on kidney cells and is the major player in the reabsorption of filtered glucose. The SGLT2 inhibitor class includes the agents canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), while sotagliflozin inhibits both SGLT1 and SGLT2.

Main results from SCORED appeared in a report first released in late 2020, and showed that for the study’s primary endpoint treatment with sotagliflozin linked with a significant 26% relative risk reduction for the composite of cardiovascular deaths, hospitalizations for heart failure, and urgent visits for heart failure (N Engl J Med. 2021 Jan 14;384[2]:129-39). Patient follow-up in SCORED was not as long as originally planned when the study stopped early due to a loss of funding from a sponsor that was triggered by the COVID-19 pandemic.

MACE results ‘heterogeneous’ from SGLT2 inhibitors

Sotagliflozin and agents from the SGLT2 inhibitor class “have been consistent” in their benefits for reducing cardiovascular death and hospitalization for heart failure, but for MACE, the results from the SGLT2 inhibitors “have been more heterogeneous,” and the effect of sotagliflozin on MACE “were different in SCORED,” commented Michelle L. O’Donoghue, MD, MPH, a cardiologist at Brigham and Women’s Hospital in Boston who was not involved with this work.

“The results suggest a benefit [from sotagliflozin] on atherosclerotic events, which could be a potential advantage” compared with the SGLT2 inhibitors, “but the heterogeneity of this effect” among these agents means that more confirmatory data are needed for sotagliflozin, Dr. O’Donoghue said in an interview.

“There is a lot of enthusiasm for the concept” of combined inhibition of the SGLT1 and 2 receptors, and if more evidence for unique benefits of this effect accumulate “it may lead to increased enthusiasm for sotagliflozin,” she said. “A lot will also depend on pricing decisions” for sotagliflozin, if it receives U.S. marketing approval from the Food and Drug Administration. Decisions about which agent from the SGLT2 inhibitor class to prescribe “are often being made based on price right now,” Dr. O’Donoghue said.

Lexicon Pharmaceuticals, the company developing sotagliflozin, has announced plans to resubmit its new drug application for sotagliflozin to the FDA later in 2022, with the agency’s approval decision likely occurring late in 2022 or sometime during 2023. In February, the company withdrew its December 2021 application to correct a “technical issue” it had found.

An additional analysis reported by Dr. Bhatt used combined data from SCORED as well as several additional randomized trials of sotagliflozin involving a total of more than 20,000 patients that showed a significant 21% reduction in the incidence of MACE compared with placebo.

During his talk, Dr. Bhatt said that sotagliflozin was potentially superior to the agents that inhibit only SGLT2. In an interview, he based this tentative assessment on at least four attributes of sotagliflozin that have emerged from trial results:

• The drug’s ability to significantly reduce MACE and to have this effect apparent within a few months of treatment onset;
• The significantly reduced rate of stroke with sotagliflozin (when patients are not subdivided into those with or without a history of CVD) that has not yet been seen with any SGLT2 inhibitor;
• The ability of sotagliflozin to reduce hemoglobin A1c levels in patients with type 2 diabetes even when their estimated glomerular filtration rate is less than 30 mL/min per 1.73 m², an effect not seen with SGLT2 inhibitors and possibly explained by sotagliflozin having an effect on gut absorption of glucose in addition to its SGLT2 inhibitory effect in the kidney;
• And the proven ability of sotagliflozin to be safe and effective when initiated in patients hospitalized for heart failure, a property that so far has only also been shown for the SGLT2 inhibitor empagliflozin in the EMPULSE trial (Nature Med. 2022 Mar;28: 568-74).

SCORED was sponsored by Sanofi and Lexicon Pharmaceuticals, the companies originally developing sotagliflozin, although with the withdrawal of Sanofi’s support, further development is now sponsored entirely by Lexicon. Dr. Bhatt received research funding from Sanofi and Lexicon that was paid to Brigham and Women’s Health, and he has been an advisor to numerous companies. Dr. O’Donoghue has been a consultant to Amgen, Janssen, and Novartis, and has received research funding from Amgen, AZ MedImmune, Intarcia, Janssen, Merck, and Novartis.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).

By answering this long-pending question, the CHAP data are “practice changing,” declared an ACC-invited commentator, Athena Poppas, MD, chief of cardiology and director of the Lifespan Cardiovascular Institute, Providence, R.I. She agreed that the need for treatment of mild chronic hypertension has been a dilemma for clinicians that is now acceptably resolved.

In this trial, 2,408 pregnant women with chronic mild hypertension defined as a blood pressure of 160/90 mm Hg were randomized to treatment with a goal blood pressure of less than 140/90 mm Hg or no treatment unless the blood pressure rose to at least 160/105. All women had singleton pregnancies. Enrollment before 23 weeks of gestation was required. Severe hypertension (at least 160/105 mm Hg) was an exclusion criterion, as were several comorbidities, such as kidney disease.
 

Combination therapy accepted for <140/90 mm Hg goal

The beta-blocker labetalol or the calcium channel blocker nifedipine as single agents were the preferred antihypertensive medications in the protocol, but other medications were permitted. To reach the blood pressure goal, the single-agent therapy was titrated to the maximum dose before starting a second agent.

After randomization the systolic and diastolic blood pressures fell in both groups, but they fell more and remained consistently lower in the active treatment group, particularly during the first 20 weeks after randomization, according to graphs displayed by Dr. Tita. Over the course of the study, the mean diastolic blood pressures were 129.5 and 132.6 mm Hg in the active treatment and control groups, respectively, while the systolic pressures were 79.1 vs. 81.5 mm Hg.

When the components of the primary outcome were evaluated separately, the greatest advantage of treatment was the reduction in the rate of severe eclampsia (23.3% vs. 29.1%; HR, 0.80: 95% confidence interval, 0.70-0.92) and preterm birth (12.2% vs. 16.7%; HR, 0.73: 95% CI, 0.60-0.89).

Across a large array of subgroups, including those with or without diabetes and those treated before or after 14 weeks of gestation, there was a consistent advantage for treatment, even if not statistically different. It is notable that 48% of patients were Black and 35% had a body mass index of at least 40. The active treatment was favored across all groups stratified by these characteristics.

Although the incidences of placental abruption (1.7% on treatment vs. 1.9% without) and fetal or neonatal death (3.5% vs. 4.3%) were lower in the active treatment group, they were uncommon events in both arms of the study. The differences did not reach statistical significance.
 

Maternal morbidity rates lower on treatment

Severe SGA, which was defined as below the 5^th percentile, was also numerically but not significantly higher in the control arm than in the group receiving treatment (5.1% vs. 5.5%), but the incidence of composite adverse maternal events was numerically lower (2.1% vs. 2.8%). The incidences of all components of maternal morbidity, such as maternal death (0.1% vs. 0.2%) pulmonary edema (0.4% vs. 0.9%), heart failure (0.1% vs. 0.1%), and acute kidney injury (0.8% vs. 1.2%), were either lower or the same on active treatment versus no treatment.

According to Dr. Tita, who called CHAP one of the largest and most diverse studies to address the value of treating mild hypertension in pregnancy, the American College of Obstetricians and Gynecologists (ACOG) is evaluating these data for changing their current guidelines for managing hypertension during pregnancy.

“The rate of chronic hypertension during pregnancy has been rising in the United States due to the increase in the average age of pregnant women and the rising rates of obesity,” Dr. Tita commented.

“We definitely needed these data,” said Mary Norine Walsh, MD, medical director, Ascension Saint Vincent Cardiovascular Research Institute, Indianapolis. Not only has the value of treating mild hypertension been unresolved, but Dr. Walsh pointed out that the rates of maternal mortality in the United States are rising and now generally exceed those of many other developed countries.

There are several features in the design of this trial that make the results even more salient to clinical practice, according to Dr. Walsh. This includes the fact that about half of patients enrolled were on Medicaid. As a result, the study confirmed benefit in what Dr. Walsh characterized as a “vulnerable” population.

“We will be busy now to make sure that our [pregnant] patients are achieving these target blood pressures,” Dr. Walsh said. She indicated that CHAP validates the treatment target of 140/90 mm Hg as a standard of care.

The results were published in the New England Journal of Medicine simultaneously with its ACC presentation.

The trial was funded by the National Heart, Lung, and Blood Institute. Dr. Tita reports research grants from Pfizer. Dr. Walsh reports a financial relationship with EBR Systems. Dr. Poppas reports no potential conflicts of interest.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).

By answering this long-pending question, the CHAP data are “practice changing,” declared an ACC-invited commentator, Athena Poppas, MD, chief of cardiology and director of the Lifespan Cardiovascular Institute, Providence, R.I. She agreed that the need for treatment of mild chronic hypertension has been a dilemma for clinicians that is now acceptably resolved.

In this trial, 2,408 pregnant women with chronic mild hypertension defined as a blood pressure of 160/90 mm Hg were randomized to treatment with a goal blood pressure of less than 140/90 mm Hg or no treatment unless the blood pressure rose to at least 160/105. All women had singleton pregnancies. Enrollment before 23 weeks of gestation was required. Severe hypertension (at least 160/105 mm Hg) was an exclusion criterion, as were several comorbidities, such as kidney disease.
 

Combination therapy accepted for <140/90 mm Hg goal

The beta-blocker labetalol or the calcium channel blocker nifedipine as single agents were the preferred antihypertensive medications in the protocol, but other medications were permitted. To reach the blood pressure goal, the single-agent therapy was titrated to the maximum dose before starting a second agent.

After randomization the systolic and diastolic blood pressures fell in both groups, but they fell more and remained consistently lower in the active treatment group, particularly during the first 20 weeks after randomization, according to graphs displayed by Dr. Tita. Over the course of the study, the mean diastolic blood pressures were 129.5 and 132.6 mm Hg in the active treatment and control groups, respectively, while the systolic pressures were 79.1 vs. 81.5 mm Hg.

When the components of the primary outcome were evaluated separately, the greatest advantage of treatment was the reduction in the rate of severe eclampsia (23.3% vs. 29.1%; HR, 0.80: 95% confidence interval, 0.70-0.92) and preterm birth (12.2% vs. 16.7%; HR, 0.73: 95% CI, 0.60-0.89).

Across a large array of subgroups, including those with or without diabetes and those treated before or after 14 weeks of gestation, there was a consistent advantage for treatment, even if not statistically different. It is notable that 48% of patients were Black and 35% had a body mass index of at least 40. The active treatment was favored across all groups stratified by these characteristics.

Although the incidences of placental abruption (1.7% on treatment vs. 1.9% without) and fetal or neonatal death (3.5% vs. 4.3%) were lower in the active treatment group, they were uncommon events in both arms of the study. The differences did not reach statistical significance.
 

Maternal morbidity rates lower on treatment

Severe SGA, which was defined as below the 5^th percentile, was also numerically but not significantly higher in the control arm than in the group receiving treatment (5.1% vs. 5.5%), but the incidence of composite adverse maternal events was numerically lower (2.1% vs. 2.8%). The incidences of all components of maternal morbidity, such as maternal death (0.1% vs. 0.2%) pulmonary edema (0.4% vs. 0.9%), heart failure (0.1% vs. 0.1%), and acute kidney injury (0.8% vs. 1.2%), were either lower or the same on active treatment versus no treatment.

According to Dr. Tita, who called CHAP one of the largest and most diverse studies to address the value of treating mild hypertension in pregnancy, the American College of Obstetricians and Gynecologists (ACOG) is evaluating these data for changing their current guidelines for managing hypertension during pregnancy.

“The rate of chronic hypertension during pregnancy has been rising in the United States due to the increase in the average age of pregnant women and the rising rates of obesity,” Dr. Tita commented.

“We definitely needed these data,” said Mary Norine Walsh, MD, medical director, Ascension Saint Vincent Cardiovascular Research Institute, Indianapolis. Not only has the value of treating mild hypertension been unresolved, but Dr. Walsh pointed out that the rates of maternal mortality in the United States are rising and now generally exceed those of many other developed countries.

There are several features in the design of this trial that make the results even more salient to clinical practice, according to Dr. Walsh. This includes the fact that about half of patients enrolled were on Medicaid. As a result, the study confirmed benefit in what Dr. Walsh characterized as a “vulnerable” population.

“We will be busy now to make sure that our [pregnant] patients are achieving these target blood pressures,” Dr. Walsh said. She indicated that CHAP validates the treatment target of 140/90 mm Hg as a standard of care.

The results were published in the New England Journal of Medicine simultaneously with its ACC presentation.

The trial was funded by the National Heart, Lung, and Blood Institute. Dr. Tita reports research grants from Pfizer. Dr. Walsh reports a financial relationship with EBR Systems. Dr. Poppas reports no potential conflicts of interest.

BOSTON – Dupilumab, a human monoclonal IgG4 antibody, was an effective treatment for prurigo nodularis (PN), improving itching and skin lesions after 12 and 24 weeks of treatment, in a phase 3 trial presented at the American Academy of Dermatology 2022 Annual Meeting.

There are currently no Food and Drug Administration–approved systemic therapies for PN. Although several treatments for the disease are used off label for the condition, such as ultraviolet light therapy and immunosuppressive agents, moderate to severe PN is usually difficult to control, noted Gil Yosipovitch, MD, director of the Miami Itch Center at the University of Miami Miller School of Medicine, Florida. He led the research and presented the findings at the conference.

“Many dermatologists feel very uncomfortable dealing with these patients because they suffer from chronicity, they are miserable, and previously, the drugs didn’t work well,” Dr. Yosipovitch told this news organization. The results from this trial “are very promising,” he said. “It opens a new field of treatment for itchy conditions.”

The trial, named LIBERTY-PN PRIME2, enrolled patients aged 18-80 who had been living with PN for at least 3 months. Patients had at least 20 lesions at baseline as well as severe itch, defined as a score of 7 or greater on the Worst Itch Numerical Rating Scale (WI-NRS). The scale ranges from 0 (no itch) to 10 (worst itch imaginable). Participants also had a history of treatment failure with medium to super-potent topical corticosteroids (TCSs), or treatment with TCSs was not medically advisable for them.

The randomized, double-blinded study enrolled 160 adults with PN. Of those, 78 were assigned to the treatment arm and received a 600-mg loading dose of dupilumab, administered subcutaneously, followed by 300-mg doses every 2 weeks for 24 weeks; 82 patients were allocated to receive placebo.

During the study, 25 patients in the placebo arm discontinued treatment. In the treatment arm, one patient was not treated and two discontinued treatment due to lack of efficacy.

The primary endpoint of the study was a reduction of at least 4 points on the WI-NRS at 12 weeks. Secondary endpoints included at least a 4-point WI-NRS reduction at 24 weeks and clear to nearly clear skin, defined as having a score of 0 or 1 on the Investigator’s Global Assessment PN-Stage (IGN PN-S). The scale ranges from 0 (clear) to 4 (severe).

At 12 weeks, 37.2% of patients given dupilumab reported a reduction of at least 4 points in WI-NRS, compared with 22.0% of patients given placebo (P = .0216). By 24 weeks, 57.7% of adults who received dupilumab achieved a greater than or equal to 4-point reduction in WI-NRS, compared with 19.5% of those who received placebo (P < .0001). Additionally, 44.9% of participants in the treatment arm achieved a score of 0 or 1 on the IGA PN-S, compared with 15.9% of those in the placebo arm (P < .0001).

Forty-four participants who received dupilumab (57.1%) and 42 participants who received placebo (51.2%) reported at least one treatment-emergent adverse event (TEAE) during the study, though none of these events were serious. The most common TEAE in the study was headache, occurring in five patients taking placebo and four patients receiving dupilumab. In the dupilumab group, there were five cases of herpes virus infection, four non-herpes skin infections, and three cases of conjunctivitis. In the placebo group, seven non-herpes skin infections were reported.

Sanofi and Regeneron, who jointly developed dupilumab, plan to file for regulatory approval for dupilumab for PN “around the world” in the first half of this year, according to a press release.

“It’s great news and a step in the right direction,” Sarina Elmariah, MD, PhD, a dermatologist at Massachusetts General Hospital and instructor of dermatology at Harvard Medical School, both in Boston, told this news organization. She was not involved with the research.

“We’re finally starting to shed light on this condition and its pathogenesis,” she said. She noted that other potential therapeutics for PN are also in development. “It’s reflective of the fact that we are making strides in this area.”

Sanofi and Regeneron Pharmaceuticals sponsored the LIBERTY-PN PRIME2 trial. Dr. Yosipovitch has reported financial relationships with Bellus Health, Eli Lilly, Galderma, GSK, Kiniksa Pharmaceuticals, LEO Pharma, Novartis, Pfizer, Regeneron, Sanofi, and Trevi Therapeutics. Dr. Elmariah is on the advisory boards of Sanofi, Galderma, and Trevi Therapeutics.

BOSTON – Requests for a medical waiver to avoid a second COVID-19 vaccine dose or a booster after cutaneous reactions to the first dose are not justified on the basis of risk, according to an analysis of several large sets of data presented at the annual meeting of the American Academy of Dermatology.

According to the data, “there are no serious adverse consequences from these cutaneous reactions,” said Esther Freeman, MD, PhD, director of Global Health Dermatology, Massachusetts General Hospital, Boston.

This is important because the risk of vaccine hesitancy goes up dramatically in patients who experience reactions to the first vaccine dose, according to follow-up of more than 50,000 employees vaccinated in the Mass General Brigham Healthcare System (MGBHS). According to Dr. Freeman, there was almost a fourfold increase in the rate of second-dose refusals for those with cutaneous reactions and a more than fourfold increase in those who developed angioedema.

Before the data were available, skin reactions were a source of concern among dermatologists and others involved in monitoring vaccine-related adverse events. Injection site reactions (ISRs) are associated with essentially every injectable vaccine, so these were expected, but a small proportion of patients developed large red plaques in the injection arm 7-8 days after the inoculation.

“These delayed reactions caused a lot of initial panic,” said Dr. Freeman, who counted herself among those alarmed about what the reactions might signify. “Was this cellulitis? Would the next dose cause anaphylaxis? We were concerned.”

This concern dissipated with the availability of more data. In a global registry that has so far captured more than 1,000 cutaneous reactions from 52 participating countries, it appears that about 2% of patients have a cutaneous reaction other than an ISR after the first dose. All resolve with minimal skin care or no treatment.

After the second dose, the proportion is lower. If there is a reaction, it typically occurs earlier and resolves more quickly.

“What we have learned is that fewer than half of patients who had a reaction to the first dose have a reaction to the second, and those who did have a reaction had a milder course,” said Dr. Freeman.

These data are “incredibly reassuring” on many levels, she explained. In addition, it allows clinicians to confidently explain to patients that there are no serious sequelae from the rashes, whether immediate or delayed, from the available COVID-19 vaccines.

“Every skin reaction I have seen is something we can treat through,” she added, noting that most reactions resolve with little or no supportive care. Following skin reactions, particularly the delayed lesions, it is not uncommon for patients to refuse a second shot. Some request a medical waiver to avoid further vaccine exposure. According to Dr. Freeman, this is unwarranted.

“I have granted exactly zero waivers,” she said. She explains to patients that these reactions have not been predictive of serious events, such as anaphylaxis. Although the trigger of the hypersensitivity reaction remains unknown, there is no evidence of serious consequences.

Delayed skin reactions are more commonly associated with the Moderna than the Pfizer vaccine. One notable difference between these vaccines is the greater content of mRNA in the Moderna formulation, but Freeman said that this is only one potential hypothesis for higher frequency of reactions to this version of the vaccine.

Patients with a history of allergic disease are more likely to develop a reaction but not significantly more likely to have a reaction that is more difficult to manage, according to Kimberly G. Blumenthal, MD, quality and safety officer for allergy, and codirector of the clinical epidemiology program in the division of rheumatology, allergy, and immunology at Mass General.

Massachusetts General Hospital

Anaphylaxis has been associated with COVD-19 vaccines just as it has with essentially every injectable vaccine, Dr. Blumenthal said during the same session. But the risk is very low, and it stays low even among those with a history of severe hypersensitivity reactions in the past.

Among the data collected from more than 52,000 vaccinated MGBHS employees, 0.9% had a history of severe allergic reaction to a prior vaccine. Of these, 11.6% had an allergic reaction to the COVID-19 vaccine. This was more than twice the 4.6% rate of allergic reactions among employees without a history of allergic reactions, but serious consequences were rare in both groups.

Of those with a reaction to the first dose, all but 2.4% took a subsequent dose. Again, serious reactions were exceedingly rare. These serious reactions did include anaphylaxis and hospitalization in 3% of patients, but there were no fatalities and all resolved.

The absence of serious sequelae from a reaction to a COVID-19 vaccine must be considered within the context of the benefit, which includes protection from death and hospitalization from the virus, according to Dr. Blumenthal. Citing the evidence that first-shot reactions are a source of vaccine hesitancy, she agreed that it is important to educate patients about relative risks.

“Even in our own cohort of MGBHS employees, we have people, including those who had been provaccine in the past, become hesitant,” commented Dr. Blumenthal, who said there are data from the Kaiser Permanente System showing similar vaccine reluctance following a first-shot reaction.

After more than 500 million doses of the Moderna and Pfizer vaccines had been administered worldwide, there was not a single reported death from anaphylaxis. Although Dr. Blumenthal said that an unconfirmed death of this type had been recently reported, she emphasized that this single death, if valid, is dwarfed by the lives saved with vaccination.

Asked about her strategy for counseling patients with vaccine hesitancy, Dr. Freeman said the body of safety data is large and compelling. There is overwhelming evidence of a favorable benefit-to-risk ratio overall and among those with a first-shot reaction.

“I can reassure them on the basis of the data,” Dr. Freeman said in an interview. “Less than half will have a reaction to the second shot and even if they do have a reaction, it is likely to be less severe.”

Although the main message is that vaccination is potentially lifesaving and far outweighs any risks, Freeman specifically gives this message to those hesitant to take a second shot after a first-shot reaction: “I can get you through it.”

Dr. Freeman encouraged health care professionals to report cases of COVID-19 vaccine–related dermatologic side effects to the American Academy of Dermatology / International League of Dermatologic Societies COVID-19 dermatology registry. Dermatologic manifestations of COVID-19 can also be reported to the registry.

Dr. Freeman disclosed receiving grants/research funding from the International League of Dermatologic Societies and from the National Institutes of Health. Dr. Blumenthal disclosed no relevant financial relationships.

This is important because the risk of vaccine hesitancy goes up dramatically in patients who experience reactions to the first vaccine dose, according to follow-up of more than 50,000 employees vaccinated in the Mass General Brigham Healthcare System (MGBHS). According to Dr. Freeman, there was almost a fourfold increase in the rate of second-dose refusals for those with cutaneous reactions and a more than fourfold increase in those who developed angioedema.

Before the data were available, skin reactions were a source of concern among dermatologists and others involved in monitoring vaccine-related adverse events. Injection site reactions (ISRs) are associated with essentially every injectable vaccine, so these were expected, but a small proportion of patients developed large red plaques in the injection arm 7-8 days after the inoculation.

“These delayed reactions caused a lot of initial panic,” said Dr. Freeman, who counted herself among those alarmed about what the reactions might signify. “Was this cellulitis? Would the next dose cause anaphylaxis? We were concerned.”

This concern dissipated with the availability of more data. In a global registry that has so far captured more than 1,000 cutaneous reactions from 52 participating countries, it appears that about 2% of patients have a cutaneous reaction other than an ISR after the first dose. All resolve with minimal skin care or no treatment.

After the second dose, the proportion is lower. If there is a reaction, it typically occurs earlier and resolves more quickly.

“What we have learned is that fewer than half of patients who had a reaction to the first dose have a reaction to the second, and those who did have a reaction had a milder course,” said Dr. Freeman.

These data are “incredibly reassuring” on many levels, she explained. In addition, it allows clinicians to confidently explain to patients that there are no serious sequelae from the rashes, whether immediate or delayed, from the available COVID-19 vaccines.

“Every skin reaction I have seen is something we can treat through,” she added, noting that most reactions resolve with little or no supportive care. Following skin reactions, particularly the delayed lesions, it is not uncommon for patients to refuse a second shot. Some request a medical waiver to avoid further vaccine exposure. According to Dr. Freeman, this is unwarranted.

“I have granted exactly zero waivers,” she said. She explains to patients that these reactions have not been predictive of serious events, such as anaphylaxis. Although the trigger of the hypersensitivity reaction remains unknown, there is no evidence of serious consequences.

Delayed skin reactions are more commonly associated with the Moderna than the Pfizer vaccine. One notable difference between these vaccines is the greater content of mRNA in the Moderna formulation, but Freeman said that this is only one potential hypothesis for higher frequency of reactions to this version of the vaccine.

Patients with a history of allergic disease are more likely to develop a reaction but not significantly more likely to have a reaction that is more difficult to manage, according to Kimberly G. Blumenthal, MD, quality and safety officer for allergy, and codirector of the clinical epidemiology program in the division of rheumatology, allergy, and immunology at Mass General.

Anaphylaxis has been associated with COVD-19 vaccines just as it has with essentially every injectable vaccine, Dr. Blumenthal said during the same session. But the risk is very low, and it stays low even among those with a history of severe hypersensitivity reactions in the past.

Among the data collected from more than 52,000 vaccinated MGBHS employees, 0.9% had a history of severe allergic reaction to a prior vaccine. Of these, 11.6% had an allergic reaction to the COVID-19 vaccine. This was more than twice the 4.6% rate of allergic reactions among employees without a history of allergic reactions, but serious consequences were rare in both groups.

Of those with a reaction to the first dose, all but 2.4% took a subsequent dose. Again, serious reactions were exceedingly rare. These serious reactions did include anaphylaxis and hospitalization in 3% of patients, but there were no fatalities and all resolved.

The absence of serious sequelae from a reaction to a COVID-19 vaccine must be considered within the context of the benefit, which includes protection from death and hospitalization from the virus, according to Dr. Blumenthal. Citing the evidence that first-shot reactions are a source of vaccine hesitancy, she agreed that it is important to educate patients about relative risks.

“Even in our own cohort of MGBHS employees, we have people, including those who had been provaccine in the past, become hesitant,” commented Dr. Blumenthal, who said there are data from the Kaiser Permanente System showing similar vaccine reluctance following a first-shot reaction.

After more than 500 million doses of the Moderna and Pfizer vaccines had been administered worldwide, there was not a single reported death from anaphylaxis. Although Dr. Blumenthal said that an unconfirmed death of this type had been recently reported, she emphasized that this single death, if valid, is dwarfed by the lives saved with vaccination.

Asked about her strategy for counseling patients with vaccine hesitancy, Dr. Freeman said the body of safety data is large and compelling. There is overwhelming evidence of a favorable benefit-to-risk ratio overall and among those with a first-shot reaction.

“I can reassure them on the basis of the data,” Dr. Freeman said in an interview. “Less than half will have a reaction to the second shot and even if they do have a reaction, it is likely to be less severe.”

Although the main message is that vaccination is potentially lifesaving and far outweighs any risks, Freeman specifically gives this message to those hesitant to take a second shot after a first-shot reaction: “I can get you through it.”

Dr. Freeman encouraged health care professionals to report cases of COVID-19 vaccine–related dermatologic side effects to the American Academy of Dermatology / International League of Dermatologic Societies COVID-19 dermatology registry. Dermatologic manifestations of COVID-19 can also be reported to the registry.

Dr. Freeman disclosed receiving grants/research funding from the International League of Dermatologic Societies and from the National Institutes of Health. Dr. Blumenthal disclosed no relevant financial relationships.

Antidopaminergic antiemetics (ADAs) that are widely used for nausea and vomiting, including that related to chemotherapy, have been associated with an increased risk of ischemic stroke in a new study from France.

The authors found that ADA users could be at a threefold increased risk of stroke shortly after the initiation of treatment.

Further analysis showed that all three ADAs studied (domperidone, metopimazine, and metoclopramide) were associated with an increased risk, especially in the first days of use, but the highest increase was found for metopimazine and metoclopramide.

The study was published online March 23, 2022, in the BMJ.

“Our results show that the risk of ischemic stroke appears to be associated with ADA use,” wrote the authors, led by Anne Bénard-Laribière, PharmD, MS, of the University of Bordeaux (France). They emphasized, however, that this is an observational study and cannot therefore establish causation.

One important note about this study is that patients with a history of cancer were specifically excluded. The authors did not elaborate on what the ADAs were being used for, other than to say that ADAs are used for nausea and vomiting of “variable origins,” and a press release noted that these drugs are often used by patients with migraine.

Hence it is not clear what relevance these findings have for patients with cancer, suggested an expert unrelated to the study, Ian Olver, MD, PhD, professorial research fellow, faculty of health and medical sciences, University of Adelaide.

“So the best that can be said, from my viewpoint, is that the ADAs studied have been associated with an increased risk of stroke in patients other than cancer patients,” he told this news organization.

In addition, he also emphasized that an observational study cannot establish causation.

For their study, the authors used data from the nationwide reimbursement database. Hence, they “needed to make the assumption that the date of reimbursement approximated to the date of administration, and that would not be the case for drugs used prophylactically prior to chemotherapy or radiotherapy,” Dr. Olver commented.

The authors were also unable to make any statement about dose and schedule. “Certainly chemotherapy-induced nausea and vomiting would require more intermittent dosing compared to noncancer uses,” Dr. Olver said. In addition, “metoclopramide in conventional doses is not very effective for this purpose and metopimazine is mainly used in Europe.”

Most patients with cancer would not be receiving these drugs, he suggested: “These days they would be receiving 5HT3 receptor antagonists and NK1 receptor antagonists and steroids.”
 

Study details

The French study investigated the risk of ischemic stroke associated with ADA use in a real-world setting. The authors conducted a case-time-control study using data from the nationwide French reimbursement health care system database Système National des Données de Santé.

They identified 2,612 patients from the database who had experienced a first ischemic stroke between 2012 and 2016 and had also received at least one reimbursement for domperidone, metopimazine, or metoclopramide during the 70-day period prior to their stroke.

The frequency of reimbursements for ADAs was compared with a risk period (1-14 days before a stroke) and three matched reference periods (57-70 days, 43-56 days, and 29-42 days before stroke).

Patients who had experienced a stroke were matched to a control group of 21,859 randomly selected healthy people who also received an ADA in the same time period.

Within the stroke cohort, 1,250 patients received an ADA at least once during the designated risk period and 1,060 in the reference periods. Among the controls, 5,128 and 13,165 received an ADA at least one time in the risk and reference periods, respectively.

This yielded a case-time-control ratio of adjusted odds ratios of 3.12, of a risk of stroke among new users. Stratification by age (<70 years and ≥70 years), sex, history of dementia, and gastroenteritis epidemic periods revealed similar results, although the highest case-time-control ratio observed in men(aOR, 3.59).

The risk of stroke appeared to increase for all ADAs, but the highest was for metopimazine (3.62-fold increase) and metoclopramide (a 3.53-fold increase), which are both drugs that have the ability to cross the blood-brain barrier.

The study was funded by Agence Nationale de Sécurité du Médicament et des Produits de Santé through a partnership with the Health Product Epidemiology Scientific Interest Group. All authors had financial support from ANSM for the submitted work; one coauthor disclosed relationships with Pfizer and Roche. Dr. Olver disclosed no relevant financial relationships.

Treatment with a glucagon-like peptide-1 (GLP-1) receptor agonist was associated with a 37% increase in the relative risk of gallbladder or biliary disease, compared with controls – especially when used at high doses, for a longer time, and for weight loss rather than type 2 diabetes – a new meta-analysis has found.

The results “indicate that physicians and patients should be concerned about the risks of gallbladder or biliary diseases with using GLP-1 agonists,” study authors Liyun He and colleagues from Peking Union Medical College, Beijing, summarize.

However, “the overall absolute risk increase for gallbladder and biliary disease with use of GLP-1 receptor agonists was small (an additional 27 cases per 10,000 persons treated per year),” they note.

“This absolute risk increase should be weighed against the benefits of treatment with GLP-1 agonists,” which include glucose control, decreased cardiovascular risk, and weight loss, they add.

The findings are from a meta-analysis of 76 randomized controlled trials of GLP-1 agonists published online March 28 in JAMA Internal Medicine.

In an accompanying editorial, Shanzay Haider, MD, and Kasia J. Lipska, MD, also characterize the absolute risk of these complications as “modest.”

“The highest risk for these complications,” they add, “occurred among individuals in the weight loss, compared with the type 2 diabetes studies (119 vs. 13 more events per 10,000 persons per year).”

“Ultimately, the decision to start, continue, or change the dose of a GLP-1 agonist should be reached through a collaborative and individualized discussion between a clinician and a patient,” Dr. Haider and Dr. Lipska, from Yale School of Medicine, New Haven, Conn., summarize.

The study authors also note that few of the trials reported biliary-related events.

“Future trials [of drugs in this class] should prespecify gallbladder and biliary diseases as potential adverse events, and fully test for and report on these outcomes,” they urge.   

Certain drugs in this class are now approved by the U.S. Food and Drug Administration for weight loss at higher doses than for type 2 diabetes – subcutaneous liraglutide (3.0 mg) and subcutaneous semaglutide (2.4 mg) – “suggesting that GLP-1 agonist drugs will increasingly be used at high doses for weight control,” the authors note.

Controversial link

The association between GLP-1 agonists and gallbladder or biliary disease is controversial, the authors write.

Several randomized controlled trials reported higher rates of gallbladder disorders in patients who received a GLP-1 agonist versus placebo, but it is not clear if this is a class effect.

Liraglutide “has drawn the most attention” about this risk, and a post-hoc analysis of the LEADER trial found a significantly increased risk of acute biliary obstruction with liraglutide versus placebo.

To investigate this, the researchers identified 76 randomized controlled trials of GLP-1 agonists in 103,371 patients that had data for the following safety outcomes: cholelithiasis (gallstones, 61 trials), cholecystitis (inflamed gallbladder, 53 trials), biliary disease (21 trials), cholecystectomy (surgical removal of the gallbladder, seven trials), and biliary cancer (12 trials).

Sixty trials were for type 2 diabetes, 13 were for weight loss, and three were for nonalcoholic steatohepatitis, polycystic ovary syndrome, and schizophrenia. They were classed as short or long (≤ 26 weeks or > 26 weeks).

The GLP-1 agonists were liraglutide (21 trials), subcutaneous semaglutide (14), dulaglutide (11), exenatide (9), albiglutide (8), oral semaglutide (8), and lixisenatide (6). 

Participants were a mean age of 58 years and 41% were women. They had a mean BMI of 31.6 kg/m² and 36.9 kg/m² in trials of GLP-1 agonists for type 2 diabetes and weight loss, respectively.  

Patients who received a GLP-1 agonist versus controls had significantly increased rates of cholelithiasis (RR, 1.27; P = .001), cholecystitis (RR, 1.36; P < .001), biliary disease (RR, 1.55; P = .02), and cholecystectomy (RR, 1.70; P < .001) but a nonsignificant increased rate of biliary cancer (RR, 1.43; P = .22).

Use of GLP-1 agonists was associated with a greater increased risk of gallbladder or biliary diseases in trials for weight loss (RR, 2.29) than in trials for type 2 diabetes or other diseases (RR, 1.27; P < .001 for interaction).

Use of these drugs was also associated with higher risks of these complications at higher doses and when given for a longer duration.     

Limitations of the meta-analysis include that the individual studies were not designed to evaluate the risk of gallbladder or biliary diseases associated with GLP-1 agonists.

Also, biliary-related events may have been under-reported, because this was not a predefined safety outcome in most of the trials. The meta-analysis lacked patient-level data, and it may have been underpowered for subgroup analyses.       

The work was supported by grants from the National Natural Science Foundation of China, the Beijing Municipal Natural Science Foundation, the Nonprofit Central Research Institute Fund of the Chinese Academy of Medical Sciences, the CAMS Innovation Fund for Medical Sciences, and the Training Program for Excellent Talents in Dongcheng District. The researchers have no relevant financial disclosures.

To investigate this, the researchers identified 76 randomized controlled trials of GLP-1 agonists in 103,371 patients that had data for the following safety outcomes: cholelithiasis (gallstones, 61 trials), cholecystitis (inflamed gallbladder, 53 trials), biliary disease (21 trials), cholecystectomy (surgical removal of the gallbladder, seven trials), and biliary cancer (12 trials).

Sixty trials were for type 2 diabetes, 13 were for weight loss, and three were for nonalcoholic steatohepatitis, polycystic ovary syndrome, and schizophrenia. They were classed as short or long (≤ 26 weeks or > 26 weeks).

The GLP-1 agonists were liraglutide (21 trials), subcutaneous semaglutide (14), dulaglutide (11), exenatide (9), albiglutide (8), oral semaglutide (8), and lixisenatide (6). 

Participants were a mean age of 58 years and 41% were women. They had a mean BMI of 31.6 kg/m² and 36.9 kg/m² in trials of GLP-1 agonists for type 2 diabetes and weight loss, respectively.  

Patients who received a GLP-1 agonist versus controls had significantly increased rates of cholelithiasis (RR, 1.27; P = .001), cholecystitis (RR, 1.36; P < .001), biliary disease (RR, 1.55; P = .02), and cholecystectomy (RR, 1.70; P < .001) but a nonsignificant increased rate of biliary cancer (RR, 1.43; P = .22).

Use of GLP-1 agonists was associated with a greater increased risk of gallbladder or biliary diseases in trials for weight loss (RR, 2.29) than in trials for type 2 diabetes or other diseases (RR, 1.27; P < .001 for interaction).

Use of these drugs was also associated with higher risks of these complications at higher doses and when given for a longer duration.     

Limitations of the meta-analysis include that the individual studies were not designed to evaluate the risk of gallbladder or biliary diseases associated with GLP-1 agonists.

Also, biliary-related events may have been under-reported, because this was not a predefined safety outcome in most of the trials. The meta-analysis lacked patient-level data, and it may have been underpowered for subgroup analyses.

Older adults taking psychotropic medication before contracting COVID-19 are at increased risk of dementia in the year following the illness, new research suggests.

Results from a large study of more than 1,700 patients who had been hospitalized with COVID showed a greater than twofold increased risk for post-COVID dementia in those taking antipsychotics and mood stabilizers/anticonvulsants – medications often used to treat schizophrenia, psychosis, bipolar disorder, and seizures.

“We know that pre-existing psychiatric illness is associated with poor COVID-19 outcomes, but our study is the first to show an association with certain psychiatric medications and dementia,” co-investigator Liron Sinvani, MD, the Feinstein Institutes for Medical Research, Manhasset, New York, said in an interview.

‘Striking’ dementia rate

Using electronic health records, the researchers evaluated pre-COVID psychotropic medication use and post-COVID dementia onset in 1,755 adults aged 65 and older. All were hospitalized with COVID-19 at Northwell Health between March 1 and April 20, 2020.

A “striking” 13% of the participants (n = 223) developed dementia within 1-year of follow-up, the investigators report.

Among the 438 patients (25%) exposed to at least one psychotropic medication before COVID-19, 105 (24%) developed dementia in the year following COVID versus 118 of 1,317 (9%) patients with no pre-COVID exposure to psychotropic medication (odds ratio, 3.2; 95% confidence interval, 2.37-4.32).

Both pre-COVID psychotropic medication use (OR, 2.7; 95% CI, 1.8-4.0, P < .001) and delirium (OR, 3.0; 95% CI, 1.9-4.6, P < .001) were significantly associated with post-COVID dementia at 1 year.

In a sensitivity analysis in the subset of 423 patients with at least one documented neurologic or psychiatric diagnosis at the time of COVID admission, and after adjusting for confounding factors, pre-COVID psychotropic medication use remained significantly linked to post-COVID dementia onset (OR, 3.09; 95% CI, 1.5-6.6, P = .002).

Drug classes most strongly associated with 1-year post-COVID dementia onset were antipsychotics (OR, 2.8, 95% CI, 1.7-4.4, P < .001) and mood stabilizers/anticonvulsants (OR, 2.4, 95% CI, 1.39-4.02, P = .001).

In a further exploratory analysis, the psychotropics valproic acid (multiple brands) and haloperidol (Haldol) had the largest association with post-COVID dementia.

Antidepressants as a class were not associated with post-COVID dementia, but the potential effects of two commonly prescribed antidepressants in older adults, mirtazapine (Remeron) and escitalopram (Lexapro), “warrant further investigation,” the researchers note.
 

Predictive risk marker?

“This research shows that psychotropic medications can be considered a predictive risk marker for post-COVID dementia. In patients taking psychotropic medications, COVID-19 could have accelerated progression of dementia after hospitalization,” lead author Yun Freudenberg-Hua, MD, the Feinstein Institutes, said in a news release.

It is unclear why psychotropic medications may raise the risk for dementia onset after COVID, the investigators note.

“It is intuitive that psychotropic medications indicate pre-existing neuropsychiatric conditions in which COVID-19 occurs. It is possible that psychotropic medications may potentiate the neurostructural changes that have been found in the brain of those who have recovered from COVID-19,” they write.

The sensitivity analysis in patients with documented neurologic and psychiatric diagnoses supports this interpretation. 

COVID-19 may also accelerate the underlying brain disorders for which psychotropic medications were prescribed, leading to the greater incidence of post-COVID dementia, the researchers write.

“It is important to note that this study is in no way recommending people should stop taking antipsychotics but simply that clinicians need to factor in a patient’s medication history while considering post-COVID aftereffects,” Dr. Freudenberg-Hua said.

“Given that the number of patients with dementia is projected to triple in the next 30 years, these findings have significant public health implications,” Dr. Sinvani added.

She noted that “care partners and health care professionals” should look for early signs of dementia, such as forgetfulness and depressive symptoms, in their patients.

“Future studies must continue to evaluate these associations, which are key for potential future interventions to prevent dementia,” Dr. Sinvani said.

The study was funded by the National Institutes of Health. Dr. Freudenberg-Hua co-owns stock and stock options from Regeneron Pharmaceuticals. Dr. Sinvani has disclosed no relevant financial relationships.

The U.S. Food and Drug Administration has approved a higher 2-mg dose of the GLP-1 agonist semaglutide (Ozempic, Novo Nordisk) for adults with type 2 diabetes, giving a higher-dose alternative to the previous maximum 1-mg dose of semaglutide, administered by subcutaneous injection once weekly.

Semaglutide is currently available as 0.5-mg and 1-mg doses.

Results from the pivotal SUSTAIN FORTE study of the 2-mg dose (which, like lower-dose semaglutide for type 2 diabetes, comes in a single-use pen injector) showed that when compared head-to-head with a 1-mg/week dose in a 40-week study with 961 randomized patients, the 2-mg regimen led to a significant average incremental reduction in A1c levels of 0.23 percentage points. The 2-mg dose also produced a significant incremental increase in weight loss, with patients losing 0.93 kg more on the higher dose.

The 2-mg dose gives patients with type 2 diabetes and clinicians an “additional option” when a bigger “shift” in blood glucose is needed, said Juan Pablo Frias, MD, National Research Institute, Los Angeles, California, who was lead investigator for SUSTAIN FORTE, in a written statement.

As well as reducing glucose levels, semaglutide has been shown to reduce the risk of major cardiovascular events in adults with type 2 diabetes and known cardiovascular disease.

Semaglutide was approved as a 2.4-mg injectable dose, as Wegovy, in 2021 for weight loss in patients with overweight or obesity.

SUSTAIN FORTE and other trials of semaglutide were sponsored by Novo Nordisk. SURPASS-2 and other trials of tirzepatide were sponsored by Lilly. Dr. Frias was lead investigator for both SUSTAIN FORTE and SURPASS-2, as well as an investigator for other trials sponsored by Lilly, Novo Nordisk, and other companies.

CHICAGO – Patients discharged to facilities rather than to home after total hip arthroplasty (THA) or total knee arthroplasty (TKA) may need more potent chemoprophylaxis than aspirin to prevent blood clots, new data suggest.

Researchers led by Stefano Muscatelli, MD, an orthopedist at Michigan Medicine, Ann Arbor, first aimed to determine whether there was an increase in risk of venous thromboembolism (VTE) in patients who were discharged to facilities such as a skilled nursing facility or inpatient rehabilitation facility, compared with those discharged to home after THA or TKA.

The second aim was to determine whether VTE risk differed between home- and non–home-discharge patients when stratified by the chemoprophylaxis prescribed to prevent VTE.

Findings were presented at the annual meeting of the American Academy of Orthopaedic Surgeons by coauthor Michael McHugh, MD, also an orthopedist at Michigan Medicine in Ann Arbor.

The agents were categorized in three groups: aspirin only; more aggressive anticoagulants, including warfarin, factor Xa inhibitor, direct thrombin inhibitor, low-molecular-weight heparin, pentasaccharide, or antiplatelet agents, with or without concurrent aspirin; and other regimens.

The researchers found that rates of VTE were higher among patients discharged to facilities.

Of 6,411 patients included in the study, the overall rate of VTE was 1.05%. Among home-discharge patients (n = 5445), rates of VTE were significantly lower than among patients discharged to facilities (n = 966) (0.83% vs. 2.26%; P < .001).

However, the researchers found there was no difference in VTE rates between non-home and home discharge in patients who received more aggressive chemoprophylaxis.

Among discharged patients who received only aspirin, rates of VTE among those discharged to home were significantly lower compared to those discharged to facilities (0.76% vs. 3.83%; P < .001).

“Smoking, BMI [body mass index], procedure type, and preoperative anticoagulation were not associated with the outcome of VTE,” Dr. McHugh said.

“Although we found VTE to continue to be an uncommon complication, non-home discharge is independently associated with higher rates of VTE. Patients should be encouraged to discharge home, but those discharged to non-home facilities after total joint arthroplasty should be considered for more potent chemoprophylaxis than aspirin,” he concluded.

Stuart J. Fischer, MD, with Summit (N.J.) Orthopaedics and Sports Medicine, who was not part of the study, told this news organization that he found the results inconclusive.

He said there is the potential for confounding because “the people who are sent to a facility after total hip or total knee are inherently less mobile and less able to take care of themselves, so they are at a higher risk for VTE. They are going to be more static.”

Dr. Fischer noted that over the past few years, there has been a movement away from anticoagulation with more aggressive agents toward aspirin, for several reasons. Providers don’t have to monitor aspirin use and can instruct patients to take it once or twice a day. Initial data seem to show that it protects well against VTE.

“The question is, in certain population of patients, is it enough? And that’s where the data are unclear,” Dr. Fischer said.

“It’s certainly a useful study, and we need to find out which methods of anticoagulation are most effective in each setting,” he said.

Limitations include that it was a retrospective review and that adverse events from more aggressive chemoprophylaxis agents were not assessed. Prophylactic regimens were chosen at the discretion of the treating surgeon.

The researchers excluded bilateral cases, conversion arthroplasty, hip hemiarthroplasty, unicompartmental knee arthroplasty, and deaths.

Dr. Muscatelli and Dr. McHugh reported no relevant financial relationships. A coauthor reported being a paid consultant for DePuy and Zimmer. Dr. Fischer reported no relevant financial relationships.

Dr. Fischer noted that over the past few years, there has been a movement away from anticoagulation with more aggressive agents toward aspirin, for several reasons. Providers don’t have to monitor aspirin use and can instruct patients to take it once or twice a day. Initial data seem to show that it protects well against VTE.

“The question is, in certain population of patients, is it enough? And that’s where the data are unclear,” Dr. Fischer said.

“It’s certainly a useful study, and we need to find out which methods of anticoagulation are most effective in each setting,” he said.

Limitations include that it was a retrospective review and that adverse events from more aggressive chemoprophylaxis agents were not assessed. Prophylactic regimens were chosen at the discretion of the treating surgeon.

The researchers excluded bilateral cases, conversion arthroplasty, hip hemiarthroplasty, unicompartmental knee arthroplasty, and deaths.

Dr. Muscatelli and Dr. McHugh reported no relevant financial relationships. A coauthor reported being a paid consultant for DePuy and Zimmer. Dr. Fischer reported no relevant financial relationships.

CHICAGO – Access to medical cannabis (MC) cut opioid prescriptions for patients with chronic noncancer back pain and patients with osteoarthritis, according to preliminary data presented at the annual meeting of the American Academy of Orthopaedic Surgeons.

For those with chronic back pain, the average morphine milligram equivalents (MME) per day dropped from 15.1 to 11.0 (n = 186; P < .01). More than one-third of the patients (38.7%) stopped taking morphine after they filled prescriptions for medical cannabis.

Opioid prescriptions were filled 6 months before access to MC and then were compared with 6 months after access to MC.

In analyzing subgroups, the researchers found that patients who started at less than 15 MME/day and more than 15 MME/day showed significant decreases after filling the MC prescription.

Almost half (48.5%) of the patients in the group that started at less than 15 MME daily dropped to 0 MME/day, and 13.5% of patients who were getting more than 15 MME/day stopped using opioids.

Data on filled opioid prescriptions were gathered from a Prescription Drug Monitoring Program (PDMP) system for patients diagnosed with chronic musculoskeletal noncancer back pain who were eligible for MC access between February 2018 and July 2019.

Medical cannabis has shown benefit in treating chronic pain, but evidence has been limited on whether it can reduce opioid use, which can lead to substance abuse, addiction, overdose, and death, the researchers noted.

Researchers found that using MC via multiple routes of administration seemed to be important.

Patients who used only a single administration route showed a statistically insignificant decrease in MME/day from 20.0 to 15.1 (n = 68; P = .054), whereas patients who used two or more routes showed a significant decrease from 13.2 to 9.5 (n = 76; P < .01).

“We have many patients who are benefiting from a single route of delivery for chronic orthopedic pain,” Ari Greis, DO, a physical medicine and rehabilitation specialist in Bryn Mawr, Pa., and a coauthor of the MC studies for both back pain and OA, said in an interview. “However, our data shows a greater reduction in opioid consumption in patients using more than one route of delivery.”

He said delivery modes in the studies included vaporized cannabis oil or flower; sublingual tinctures; capsules or tablets; and topical lotions, creams, and salves.

Dr. Greis is the director of the medical cannabis department at Rothman Orthopaedic Institute in Bryn Mawr, and is a senior fellow in the Institute of Emerging Health Professions and the Lambert Center for the Study of Medicinal Cannabis and Hemp, both in Philadelphia.
 

Medical cannabis also reduces opioids for OA

The same team of researchers, using the data from the PDMP system, showed that medical cannabis also helped reduce opioid use for osteoarthritis.

For patients using opioids for OA, there was a significant decrease in average MME/day of prescriptions filled by patients following MC access – from 18.2 to 9.8 (n = 40; P < .05). The average drop in MME/day was 46.3%. The percentage of patients who stopped using opioids was 37.5%. Pain score on a 0-10 visual analog scale decreased significantly from 6.6 (n = 36) to 5.0 (n = 26; P < .01) at 3 months and 5.4 (n = 16; P < .05) at 6 months.

Gary Stewart, MD, an orthopedic surgeon in Morrow, Ga., who was not part of the studies, told this news organization that the studies offer good preliminary data to offer help with the opioid issue.

“I sometimes feel that we, as orthopedic surgeons and physicians in general, are working with one hand behind our back. We’re taking something that is a heroin or morphine derivative and giving it to our patients when we know it has a high risk of building tolerance and addiction. But at the same time, we have no alternative,” he said.

He said it’s important to remember the results from the relatively small study are preliminary and observational. People used different forms and amounts of MC and the data show only that prescriptions were filled, but not whether the cannabis was used. Prospective, controlled studies where opioids go head-to-head with MC are needed, he said.

“Still, this can lead us to more studies to give us an option [apart from] an opioid that we know is highly addictive,” he said.

Dr. Stewart is a member of the AAOS Opioid Task Force. Dr. Greis and several coauthors have disclosed no relevant financial relationships, and other coauthors report financial ties to companies unrelated to the research presented.
