Study: Immune checkpoint inhibitors don’t increase risk of death in cancer patients with COVID-19
The study included 113 cancer patients who had laboratory-confirmed COVID-19 within 12 months of receiving immune checkpoint inhibitor therapy. The patients did not receive chemotherapy within 3 months of testing positive for COVID-19.
In all, 33 patients were admitted to the hospital, including 6 who were admitted to the ICU, and 9 patients died.
“Nine out of 113 patients is a mortality rate of 8%, which is in the middle of the earlier reported rates for cancer patients in general [7.6%-12%],” said Aljosja Rogiers, MD, PhD, of the Melanoma Institute Australia in Sydney.
COVID-19 was the primary cause of death in seven of the patients, including three of those who were admitted to the ICU, Dr. Rogiers noted.
He reported these results during the AACR virtual meeting: COVID-19 and Cancer.
Study details
Patients in this study were treated at 19 hospitals in North America, Europe, and Australia, and the data cutoff was May 15, 2020. Most patients (64%) were treated in Europe, which was the epicenter for the COVID-19 pandemic at the time of data collection, Dr. Rogiers noted. A third of patients were in North America, and 3% were in Australia.
The patients’ median age was 63 years (range, 27-86 years). Most patients were men (65%), and most had Eastern Cooperative Oncology Group performance scores of 0-1 (90%).
The most common malignancies were melanoma (57%), non–small cell lung cancer (17%), and renal cell carcinoma (9%). Treatment was for early cancer in 26% of patients and for advanced cancer in 74%. Comorbidities included cardiovascular disease in 27% of patients, diabetes in 15%, pulmonary disease in 12%, and renal disease in 5%.
Immunosuppressive therapy equivalent to a prednisone dose of 10 mg or greater daily was given in 13% of patients, and other immunosuppressive therapies, such as infliximab, were given in 3%.
Among the 60% of patients with COVID-19 symptoms, 68% had fever, 59% had cough, 34% had dyspnea, and 15% had myalgia. Most of the 40% of asymptomatic patients were tested because they had COVID-19–positive contact, Dr. Rogiers noted.
Immune checkpoint inhibitor treatment included monotherapy with a programmed death–1/PD–ligand 1 inhibitor in 82% of patients, combination anti-PD-1 and anti-CTLA4 therapy in 13%, and other therapy – usually a checkpoint inhibitor combined with a different type of targeted agent – in 5%.
At the time of COVID-19 diagnosis, 30% of patients had achieved a partial response, complete response, or had no evidence of disease, 18% had stable disease, and 15% had progression. Response data were not available in 37% of cases, usually because treatment was only recently started prior to COVID-19 diagnosis, Dr. Rogiers said.
Treatments administered for COVID-19 included antibiotic therapy in 25% of patients, oxygen therapy in 20%, glucocorticoids in 10%, antiviral drugs in 6%, and intravenous immunoglobulin or anti–interleukin-6 in 2% each.
Among patients admitted to the ICU, 3% required mechanical ventilation, 2% had vasopressin, and 1% received renal replacement therapy.
At the data cutoff, 20 of 33 hospitalized patients (61%) had been discharged, and 4 (12%) were still in the hospital.
Mortality results
Nine patients died. The rate of death was 8% overall and 27% among hospitalized patients.
“The mortality rate of COVID-19 in the general population without comorbidities is about 1.4%,” Dr. Rogiers said. “For cancer patients, this is reported to be in the range of 7.6%-12%. To what extent patients on immune checkpoint inhibition are at a higher risk of mortality is currently unknown.”
Theoretically, immune checkpoint inhibition could either mitigate or exacerbate COVID-19 infection. It has been hypothesized that immune checkpoint inhibitors could increase the risk of severe acute lung injury or other complications of COVID-19, Dr. Rogiers said, explaining the rationale for the study.
The study shows that the patients who died had a median age of 72 years (range, 49-81 years), which is slightly higher than the median overall age of 63 years. Six patients were from North America, and three were from Italy.
“Two melanoma patients and two non–small cell lung cancer patients died,” Dr. Rogiers said. He noted that two other deaths were in patients with renal cell carcinoma, and three deaths were in other cancer types. All patients had advanced or metastatic disease.
Given that 57% of patients in the study had melanoma and 17% had NSCLC, this finding may indicate that COVID-19 has a slightly higher mortality rate in NSCLC patients than in melanoma patients, but the numbers are small, Dr. Rogiers said.
Notably, six of the patients who died were not admitted to the ICU. In four cases, this was because of underlying malignancy; in the other two cases, it was because of a constrained health care system, Dr. Rogiers said.
Overall, the findings show that the mortality rate of patients with COVID-19 and cancer treated with immune checkpoint inhibitors is similar to the mortality rate reported in the general cancer population, Dr. Rogiers said.
“Treatment with immune checkpoint inhibition does not seem to pose an additional mortality risk for cancer patients with COVID-19,” he concluded.
Dr. Rogiers reported having no conflicts of interest. There was no funding disclosed for the study.

Novel probiotic shows promise in treating type 2 diabetes
A novel probiotic product (Pendulum Glucose Control) containing gut bacteria strains that are deficient in people with type 2 diabetes modestly improves blood glucose levels, new research suggests.
The findings were published in BMJ Open Diabetes Research & Care by Fanny Perraudeau, PhD, and colleagues, all employees of Pendulum Therapeutics.
The product, classified as a medical food, is currently available for purchase on the company’s website without a prescription.
It contains the oligosaccharide-consuming Akkermansia muciniphila and Bifidobacterium infantis, the butyrate producers Anaerobutyricum hallii, Clostridium beijerinckii, and Clostridium butyricum, along with the “prebiotic” dietary fiber inulin.
In the 12-week trial of people with type 2 diabetes who were already taking metformin, with or without a sulfonylurea, 23 were randomized to the product and 26 received placebo capsules.
Participants in the active-treatment arm had significantly reduced glucose levels after a 3-hour standard meal-tolerance test, by 36.1 mg/dL (P = .05), and average A1c reduction of 0.6 percentage points (P = .054), compared with those taking placebo.
There were no major safety or tolerability issues, only transient gastrointestinal symptoms (nausea, diarrhea) lasting 3-5 days. No changes were seen in body weight, insulin sensitivity, or fasting blood glucose.
Asked to comment on the findings, Nanette I. Steinle, MD, an endocrinologist with expertise in nutrition who was not involved in the research, said that “to me it looks like the research was designed well and they didn’t overstate the results. ... I would say, for folks with mild to modest blood glucose elevations, it could be helpful to augment a healthy lifestyle.”
However, the product is not cheap, so cost could be a limiting factor for some patients, said Dr. Steinle, who is associate professor of medicine at the University of Maryland, Baltimore, and chief of the endocrine section, Maryland Veterans Affairs Health Care System.
Lead author Orville Kolterman, MD, chief medical officer at Pendulum, said in an interview that the formulation’s specificity distinguishes it from most commercially available probiotics.
“The ones sold in stores are reconfigurations of food probiotics, which are primarily aerobic organisms, whereas the abnormalities in the microbiome associated with type 2 diabetes reside in anaerobic organisms, which are more difficult to manufacture,” he explained.
The fiber component, inulin, is important as well, he said. “This product may make the dietary management of type 2 diabetes more effective, in that you need both the fiber and the microbes to ferment the fiber and produce short-chain fatty acids that appear to be very important for many reasons.”
The blood glucose-lowering effect is related in part to the three organisms’ production of butyrate, which binds to epithelial cells in the gut to secrete glucagonlike peptide–1, leading to inhibition of glucagon secretion among other actions.
And Akkermansia muciniphila protects the gut epithelium and has shown some evidence of improving insulin sensitivity and other beneficial metabolic effects in humans.
Dr. Kolterman, who was with Amylin Pharmaceuticals prior to moving to Pendulum, commented: “After doing this for 30 years or so, I’ve come to the strong appreciation that whenever you can do something to move back toward what Mother Nature set up, you’re doing a good thing.”
Clinically, Dr. Kolterman said, “I think perhaps the ideal place to try this would be shortly after diagnosis of type 2 diabetes, before patients go on to pharmacologic therapy.”
However, for practical reasons the study was done in patients who were already taking metformin, he said. “The results we have are that it’s beneficial above and beyond metformin, since [these] patients weren’t controlled with metformin.”
He also noted that it might benefit patients who can’t tolerate metformin or who have prediabetes; there’s an ongoing investigator-initiated study of the latter.
Dr. Steinle also endorsed the possibility that the product may benefit people with prediabetes. “I would suspect this could be very helpful to augment attempts to prevent diabetes. ... The group with prediabetes is huge.”
However, she cautioned, “if the blood glucose is over 200 [mg/dL], I wouldn’t think a probiotic would get them where they need to go.”
Overall, she pointed out that targeting the microbiome is a very active and potentially important field of medical research, and that it has received support from the National Institutes of Health. “I think we’re in the early stages of understanding how what grows in us, and on us, impacts our health and how we may be able to use these organisms to our benefit. I would expect we’ll see more of these probiotics being marketed in various forms.”
Dr. Kolterman is an employee of Pendulum. Dr. Steinle has reported receiving funding from the NIH, and she is conducting a study funded by Kowa through the VA.

All NSAIDs raise post-MI risk but some are safer than others: Next chapter
Patients on antithrombotics after an acute MI will face a greater risk for bleeding and secondary cardiovascular (CV) events if they start taking any nonaspirin NSAID, confirms a large observational study.
Like other research before it, the new study suggests those risks will be much lower for some nonaspirin NSAIDs than others. But it may also challenge at least some conventional thinking about the safety of these drugs, and is based solely on a large cohort in South Korea, a group for which such NSAID data has been in short supply.
“It was intriguing that our study presented better safety profiles with celecoxib and meloxicam versus other subtypes of NSAIDs,” noted the report, published online July 27 in the Journal of the American College of Cardiology.
Most of the NSAIDs included in the analysis, “including naproxen, conferred a significantly higher risk for cardiovascular and bleeding events, compared with celecoxib and meloxicam,” wrote the authors, led by Dong Oh Kang, MD, Korea University Guro Hospital, Seoul, South Korea.
A main contribution of the study “is the thorough and comprehensive evaluation of the Korean population by use of the nationwide prescription claims database that reflects real-world clinical practice,” senior author Cheol Ung Choi, MD, PhD, of the same institution, said in an interview.
“Because we included the largest number of patients of any comparable clinical studies on NSAID treatment after MI thus far, our study may allow the generalizability of the adverse events of NSAIDs to all patients by constituting global evidence encompassing different population groups,” Dr. Choi said.
The analysis has limitations along with its strengths, the authors acknowledged, including its observational design and potential for confounding not addressed in statistical adjustments.
Observers of the study concurred, but some cited evidence pointing to such confounding that is serious enough to question the entire study’s validity.
Among the cohort of more than 100,000 patients followed for an average of about 2.3 years after their MI, the adjusted risk of thromboembolic CV events went up almost 7 times for those who took any NSAID for at least 4 consecutive weeks, compared with those who didn’t take NSAIDs, based on prescription records.
Their adjusted risk of bleeding events – which included gastrointestinal, intracranial, respiratory, or urinary tract bleeding or posthemorrhagic anemia, the group writes – was increased 300%.
There was wide variance in the adjusted hazard ratios for outcomes by type of NSAID. The risk of CV events climbed from a low of about 3 with meloxicam and almost 5 for celecoxib to more than 10 and 12 for naproxen and dexibuprofen, respectively.
The hazard ratios for bleeding ranged from about 3 for both meloxicam and celecoxib to more than 6 for naproxen.
Of note, celecoxib and meloxicam both preferentially target the cyclooxygenase type 2 (COX-2) pathway, and naproxen among NSAIDs once had a reputation for relative cardiac safety, although subsequent studies have challenged that notion.
“On the basis of the contemporary guidelines, NSAID treatment should be limited as much as possible after MI; however, our data suggest that celecoxib and meloxicam could be considered possible alternative choices in patients with MI when NSAID prescription is unavoidable,” the group wrote.
They acknowledged some limitations of the analysis, including an observational design and the possibility of unidentified confounders; that mortality outcomes were not available from the National Health Insurance Service database used in the study; and that the 2009-2013 span for the data didn’t allow consideration of more contemporary antiplatelet agents and direct oral anticoagulants.
Also, NSAID use was based on prescriptions without regard to over-the-counter usage. Although use of over-the-counter NSAIDs is common in Korea, “most MI patients in Korea are prescribed most medications, including NSAIDs, in the hospital. So I think that usage of over-the-counter NSAIDs did not change the results,” Dr. Choi said.
“This study breaks new ground by demonstrating cardiovascular safety of meloxicam (and not only of celecoxib), probably because of its higher COX-2 selectivity,” wrote the authors of an accompanying editorial, Juan J. Badimon, PhD, and Carlos G. Santos-Gallego, MD, both of the Icahn School of Medicine at Mount Sinai, New York.
Notably, “this paper rejects the cardiovascular safety of naproxen, which had been suggested classically and in the previous Danish data, but that was not evident in this study.” The finding is consistent with the PRECISION trial, in which both bleeding and CV risk were increased with naproxen versus other NSAIDs, observed Dr. Badimon and Dr. Santos-Gallego.
They agreed with the authors in recommending that, “although NSAID treatment should be avoided in patients with MI, if the use of NSAIDs is inevitable due to comorbidities, the prescription of celecoxib and meloxicam could be considered as alternative options.”
But, “as no study is perfect, this article also presents some limitations,” the editorial agreed, citing some of the same issues noted by Dr. Kang and associates, along with potential confounding by indication and the lack of “clinical information to adjust (e.g., angiographic features, left ventricular function).”
“There’s undoubtedly residual confounding,” James M. Brophy, MD, PhD, a pharmacoepidemiologist at McGill University, Montreal, said in an interview.
The 400%-900% relative risks for CV events “are just too far in left field, compared to everything else we know,” he said. “There has never been a class of drugs that have shown this sort of magnitude of effect for adverse events.”
Even in PRECISION with its more than 24,000 high-coronary-risk patients randomized and followed for 5 years, Dr. Brophy observed, relative risks for the different NSAIDs varied by an order of magnitude of only 1-2.
“You should be interpreting things in the context of what is already known,” Dr. Brophy said. “The only conclusion I would draw is the paper is fatally flawed.”
The registry included 108,232 primarily male patients followed from their first diagnosed MI for CV and bleeding events. About 1.9% were prescribed at least one NSAID for 4 or more consecutive weeks during the follow-up period averaging 2.3 years, the group reported.
The most frequently prescribed NSAID was diclofenac, at about 72% of prescribed NSAIDs in the analysis for CV events and about 69% in the bleeding-event analysis.
Adding any NSAID to post-MI antithrombotic therapy led to an adjusted HR of 6.96 (P < .001) for CV events and 4.08 (P < .001) for bleeding events, compared with no NSAID treatment.
The 88% of the cohort who were on dual-antiplatelet therapy with aspirin and clopidogrel showed very nearly the same risk increases for both endpoints.
Further studies are needed to confirm the results “and ensure their generalizability to other populations,” Dr. Choi said. They should be validated especially using the claims data bases of countries near Korea, “such as Japan and Taiwan, to examine the reproducibility of the results in similar ethnic populations.”
That the study focused on a cohort in Korea is a strength, contended the authors as well as Dr. Badimon and Dr. Santos-Gallego, given “that most data about NSAIDs were extracted from Western populations, but the risk of thrombosis/bleeding post-MI varies according to ethnicity,” according to the editorial
Dr. Brophy agreed, but doubted that ethnic differences are responsible for variation in relative risks between the current results and other studies. “There are pharmacogenomic differences between different ethnicities as to how they activate these drugs. But I suspect that sort of difference is really minor. Maybe it leads to a 2% or a 5% difference in risks.”
Dr. Kang and associates, Dr. Badimon, Dr. Santos-Gallego, and Dr. Brophy disclosed no relevant financial relationships.

Patients on antithrombotics after an acute MI will face a greater risk for bleeding and secondary cardiovascular (CV) events if they start taking any nonaspirin NSAID, confirms a large observational study.
Like other research before it, the new study suggests those risks will be much lower for some nonaspirin NSAIDs than others. But it may also challenge at least some conventional thinking about the safety of these drugs, and is based solely on a large cohort in South Korea, a group for which such NSAID data has been in short supply.
“It was intriguing that our study presented better safety profiles with celecoxib and meloxicam versus other subtypes of NSAIDs,” noted the report, published online July 27 in the Journal of the American College of Cardiology.
Most of the NSAIDs included in the analysis, “including naproxen, conferred a significantly higher risk for cardiovascular and bleeding events, compared with celecoxib and meloxicam,” wrote the authors, led by Dong Oh Kang, MD, Korea University Guro Hospital, Seoul, South Korea.
A main contribution of the study “is the thorough and comprehensive evaluation of the Korean population by use of the nationwide prescription claims database that reflects real-world clinical practice,” senior author Cheol Ung Choi, MD, PhD, of the same institution, said in an interview.
“Because we included the largest number of patients of any comparable clinical studies on NSAID treatment after MI thus far, our study may allow the generalizability of the adverse events of NSAIDs to all patients by constituting global evidence encompassing different population groups,” Dr. Choi said.
The analysis has limitations along with its strengths, the authors acknowledged, including its observational design and potential for confounding not addressed in statistical adjustments.
Observers of the study concurred, but some cited evidence pointing to such confounding that is serious enough to question the entire study’s validity.
Among the cohort of more than 100,000 patients followed for an average of about 2.3 years after their MI, the adjusted risk of thromboembolic CV events went up almost 7 times for those who took any NSAID for at least 4 consecutive weeks, compared with those who didn’t take NSAIDs, based on prescription records.
Their adjusted risk of bleeding events – which included gastrointestinal, intracranial, respiratory, or urinary tract bleeding or posthemorrhagic anemia, the group writes – was increased 300%.
There was wide variance in the adjusted hazard ratios for outcomes by type of NSAID. The risk of CV events climbed from a low of about 3 with meloxicam and almost 5 for celecoxib to more than 10 and 12 for naproxen and dexibuprofen, respectively.
The hazard ratios for bleeding ranged from about 3 for both meloxicam and celecoxib to more than 6 for naproxen.

New psoriasis guidelines focus on topical and alternative treatments, and severity measures
and the National Psoriasis Foundation.
The guidelines, published in the Journal of the American Academy of Dermatology, focus on treatment for adults, and follow the release of other AAD-NPF guidelines on biologics for psoriasis, psoriasis-related comorbidities, pediatric psoriasis, and phototherapy in 2019, and earlier this year, guidelines for systemic nonbiologic treatments. The latest guidelines’ section on topical treatment outlines evidence for the efficacy, effectiveness, and adverse events related to topical steroids, topical tacrolimus and pimecrolimus, vitamin D analogues, tazarotene, moisturizers, salicylic acid, anthralin, coal tar, combinations with biologic agents, and combinations with nonbiologic treatments (methotrexate, cyclosporine, acitretin, and apremilast).
The guidelines noted the “key role” of topical corticosteroids in treating psoriasis “especially for localized disease,” and include a review of the data on low-, moderate-, high-, and ultrahigh-potency topical steroids for psoriasis.
In general, all topical steroids can be used in combination with biologics, according to the guidelines, but the strongest recommendations based on the latest evidence include the addition of an ultra-high potency topical corticosteroid to standard dose etanercept for 12 weeks. Currently, 11 biologics are approved by the Food and Drug Administration for the treatment of psoriasis.
In addition, “while not FDA approved for psoriasis, the topical calcineurin inhibitors tacrolimus and pimecrolimus are often employed in the treatment of psoriasis,” can be helpful for “thinner skin such as facial and intertriginous areas,” and can be steroid sparing when used for more than 4 weeks, according to the guidelines.
Don’t discount the role of patient preferences when choosing topical treatments, the authors noted. “The optimal vehicle choice is the one the patient is mostly likely to use.”
The guidelines also address the evidence for effectiveness, and adverse events in the use of several alternative medicines for psoriasis including traditional Chinese medicine, and the herbal therapies aloe vera and St. John’s wort, as well as the potential role of dietary supplements including fish oil, vitamin D, turmeric, and zinc in managing psoriasis, and the potential role of a gluten-free diet.
In general, research on the efficacy, effectiveness, and potential adverse effects of these strategies are limited, according to the guidelines, although many patients express interest in supplements and herbal products. For example, “Many patients ask about the overall role of vitamin D in skin health. Rather than adding oral vitamin D supplementation, topical therapy with vitamin D agents is effective for the treatment of psoriasis,” the authors noted.
In addition, they noted that mind/body strategies, namely hypnosis and stress reduction or meditation techniques, have been shown to improve symptoms and can be helpful for some patients, but clinical evidence is limited.
The guidelines also addressed methods for assessing disease severity in psoriasis. They recommended using body surface area (BSA) to assess psoriasis severity and patient response to treatment in the clinical setting. However, BSA is a provider assessment tool that “does not take into account location on the body, clinical characteristics of the plaques, symptoms, or quality of life issues,” the authors noted. The Psoriasis Area and Severity Index (PASI) measures erythema, induration, and scaling and is more suited to assessing psoriasis severity and response to treatment in clinical trials rather than in practice, they said.
Prior AAD guidelines on psoriasis were published more than 10 years ago, and major developments including the availability of new biologic drugs and new data on comorbidities have been recognized in the past decade, working group cochair and author of the guidelines Alan Menter, MD, said in an interview.
The key game-changers from previous guidelines include the full section published on comorbidities plus the development of two new important cytokine classes: three IL-17 drugs and three new IL-23 drugs now available for moderate to severe psoriasis, said Dr. Menter, chairman of the division of dermatology at Baylor University Medical Center, Dallas.
Barriers to implementing the guidelines in practice may occur when “third party payers make the decision on which of the 11 biologic drugs now approved for moderate to severe psoriasis should be used,” he noted.
As for next steps in psoriasis studies, “new biomarker research is currently underway,” Dr. Menter said. With 11 biologic agents new formally approved by the FDA for moderate to severe psoriasis, the next steps are to determine which drug is likely to be the most appropriate for each individual patient.
Dr. Menter disclosed relationships with multiple companies that develop and manufacture psoriasis therapies, including Abbott Labs, AbbVie, Amgen, Eli Lilly and Company, Galderma USA, Janssen Pharmaceuticals, LEO Pharma US, Menlo Therapeutics, and Novartis. The updated guidelines were designed by a multidisciplinary work group of psoriasis experts including dermatologists, a rheumatologist, a cardiologist, and representatives from a patient advocacy organization.

Most younger MI patients wouldn’t get statins under guidelines
Clinical guidelines for cholesterol management may have two blind spots when it comes to heart attack prevention: Most younger adults with premature coronary artery disease who’ve had a myocardial infarction don’t meet guideline criteria for preventative statin therapy, and survivors under age 55 don’t meet the criteria for continuing nonstatin lipid-lowering treatments, a large single-center retrospective study has shown.
“The classic approach we’ve taken to identifying young adults for prevention is inadequate in younger adults,” corresponding author Ann Marie Navar, MD, PhD, of Duke University, Durham, N.C., said in an interview. “While awaiting more definitive research we should at minimum be using all the tools at our disposal, including broader use of coronary artery calcium [CAC] scoring, to identify young people who may benefit from statin therapy.”
The retrospective observational study analyzed records of 6,639 adults who had cardiac catheterization at Duke University Medical Center from 1995 to 2012 for a first myocardial infarction with obstructive coronary artery disease. The study considered those under age 55 years as “younger” patients, comprising 41% of the study group (2,733); 35% were “middle-aged” at 55-65 years (2,324) and 24% were “older,” at 66-75 years (1,582).
The report, published online Aug. 3 in the Journal of the American College of Cardiology, noted that most of the adults with premature CAD did not meet criteria for preventative statin therapy before their first MI based on ACC/American Heart Association clinical guidelines from 2013 and 2018. It also noted that younger MI survivors are also less frequently eligible for secondary prevention with intensive nonstatin lipid-lowering therapies than are older adults despite a much longer potential life span – and opportunity for another MI – for the former.
The researchers sought to evaluate the real-world implications of changes made in the 2018 guideline for adults who develop premature ischemic heart disease, and found that fewer younger patients qualify for preventative statin therapy under the 2018 guidelines.
“Younger individuals with very high-risk criteria are at higher risk of major adverse cardiovascular events, a finding supporting the appropriate implementation of intensive lipid-lowering therapies in these patients,” wrote lead author Michel Zeitouni, MD, MSc, and colleagues.
Key findings
The investigators reported that younger adults were significantly less likely to meet a class I recommendation for statins under the 2013 guideline (42.9%), compared with their middle-aged (70%) and older (82.5%) counterparts; and under the 2018 guideline, at 39.4%, 59.5%, and 77.4%, respectively (both P < .001).
Similarly, when both class I and class IIa recommendations were accounted for, younger patients were significantly less likely than were middle-aged and older patients to be eligible for statins before their index MI under both the 2013 (56.7%, 79.5%, and 85.2%, respectively and 2018 guidelines (46.4%, 73.5%, and 88.2%, respectively (both P < .01).
After their first MI, one in four younger patients (28.3%) met the very high-risk criteria compared with 40% of middle-aged and 81.4% of older patients (P trend < .001). In 8 years of follow-up, patients with very high-risk criteria based on the 2018 guideline had twice the rate of death, nonfatal MI, or stroke (hazard ratio [HR]: 2.15; 95% confidence interval, 1.98-2.33; P < .001).
The researchers acknowledged that the 2018 guideline took the important step of implementing risk enhancers – patient characteristics such as obesity and metabolic syndrome – along with the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score to better identify high-risk young individuals who need statins. However, they also noted that the ability of the guidelines to identify young adults before their first MI “remains suboptimal.”
How to protect younger patients
“The 2018 guidelines will be most effective if we as providers do our best to identify risk enhancers and if we can use CAC scoring more broadly,” Dr. Navar said, noting that although CAC scoring has been shown to improve risk prediction, insurance coverage can be problematic.
“We also need to be careful to screen for the presence of the risk enhancers, such as inflammatory disease, family history, and women-specific risk factors, to make sure we aren’t missing an important high-risk group,” she added.
Other solutions to better identify at-risk younger adults include considering upgrades to the guidelines’ class IIb recommendation to class IIa to emphasize the importance of recognizing lower-risk younger adults, and recommending statins for patients at higher lifetime risk than age- and sex-matched peers, the researchers noted. “In our cohort, young individuals admitted for a first MI had a higher lifetime ASCVD risk score than did patients in the older age categories,” Dr. Zeitouni and colleagues wrote.
Dr. Navar said that these findings are a reminder that guidelines aren’t mandates. “Guidelines are meant to be a starting point for patients and physicians,” she said. “The absence of a recommendation doesn’t mean something isn’t recommended, but that there is not enough data to say one way or another.”
The study “provides important evidence” that the 2018 guidelines exempted about half of the younger adults who had a first MI from preventative statin therapy, Ron Blankstein, MD, and Avinainder Singh, MD, MMSc, noted in an editorial (J Am Coll Cardiol. 2020;76:665-8).
“Data from both the Duke and Young-MI registries should force us to reexamine how we allocate statin use among young individuals,” they noted. Dr. Blankstein is with Brigham and Women’s Hospital, Harvard Medical School, Boston. Dr. Singh is with Yale University, New Haven, Conn.
Dr. Zeitouni reported receiving lecture fees from Bristol-Myers Squibb/Pfizer. Dr. Navar reported financial relationships with Amarin, Janssen, Amgen, Sanofi and Regeneron Pharmaceuticals, AstraZeneca, Esperion, Novo Nordisk, Novartis, The Medicine Company, New Amsterdam, Cerner and Pfizer.

FDA okays new indication for esketamine nasal spray
The Food and Drug Administration has approved the supplemental new drug application for esketamine nasal spray (Spravato, Janssen Pharmaceuticals) to treat depressive symptoms in adults with major depressive disorder (MDD) and acute suicidal ideation or behavior.
The FDA approved esketamine nasal spray for treatment-resistant depression in March 2019, as reported by Medscape Medical News.
– which evaluated the efficacy and safety of the nasal spray in addition to a comprehensive standard of care in adults with MDD who had active suicidal ideation with intent.
The standard of care included initial hospitalization, a newly initiated or optimized oral antidepressant, and twice-weekly treatment visits for 4 weeks. During that time, patients received esketamine nasal spray 84 mg or placebo nasal spray.
Results from the trials showed that the active treatment significantly reduced depressive symptoms within 24 hours, with some patients starting to respond as early as 4 hours after the first dose.
“Traditional oral antidepressants need weeks or more to take effect, so the availability of a medicine that can begin providing relief within a day is potentially life changing,” Theresa Nguyen, chief program officer at Mental Health America, said in a company news release.
“The clinical trials supporting this new indication provide compelling evidence that esketamine may offer clinicians a new way to provide support to patients quickly in the midst of an urgent depressive episode and help set them on the path to remission,” Gerard Sanacora, MD, PhD, director of the Yale Depression Research Program, New Haven, Conn., and esketamine clinical trial investigator, said in the same release.
A full course of treatment for MDD with acute suicidal ideation or behavior is twice weekly for 4 weeks, “after which evidence of therapeutic benefit should be evaluated to determine need for continued treatment,” the company said.
Because of the risk for serious adverse events, including sedation and dissociation, and the potential for abuse or misuse, esketamine nasal spray is only available through a restricted distribution system – the Spravato Risk Evaluation and Mitigation Strategy (REMS).
The patient self-administers esketamine nasal spray only in REMS-certified health care settings. Patients are not permitted to take the drug home.
Full prescribing information is available online.

Real-world data show SGLT2 inhibitors for diabetes triple DKA risk
according to a new large database analysis.
The findings, which include data on the use of three different SGLT2 inhibitors in Canada and the United Kingdom and suggest a class effect, were published online July 27 in Annals of Internal Medicine by Antonios Douros, MD, PhD, of McGill University and the Centre for Clinical Epidemiology, Lady Davis Institute, Montreal, and colleagues.
“Our results provide robust evidence that SGLT2 inhibitors are associated with an increased risk for DKA. Of note, increased risks were observed in all molecule-specific analyses, with canagliflozin [Invokana, Janssen] showing the highest effect estimate,” they noted.
And because the beneficial effects of SGLT2 inhibitors in the prevention of cardiovascular and renal disease will probably increase their uptake in the coming years, “Physicians should be aware of DKA as a potential adverse effect,” Dr. Douros and colleagues wrote.
Analysis “generally confirms what has already been published”
Asked for comment, Simeon I. Taylor, MD, PhD, professor of medicine at the University of Maryland, Baltimore, said that the study “generally confirms what has already been published” on the topic. He noted that overall “the risk of SGLT2 inhibitor–induced ketoacidosis is quite low in type 2 diabetes, perhaps on the order of 1 episode per 1000 patient-years.”
However, Dr. Taylor cautioned: “Published evidence suggests that the risk of DKA is increased if patients are unable to eat,” such as when hospitalized patients are not permitted to eat.
“In that setting, it is probably prudent to discontinue an SGLT2 inhibitor. Also, it may be prudent not to prescribe SGLT2 inhibitors to patients with a history of DKA,” he added.
Dr. Taylor also advised: “Although not necessarily supported by this publication, I think that caution should be exercised in prescribing SGLT2 inhibitors to insulin-dependent type 2 diabetes patients. ... Some late-stage type 2 diabetes patients may have severe insulin deficiency, and their physiology may resemble that of a type 1 diabetes patient.”
Dr. Taylor has previously advised against using SGLT2 inhibitors altogether in patients with type 1 diabetes.
Increased DKA risk seen across all SGLT2 inhibitors
The study involved electronic health care databases from seven Canadian provinces and the United Kingdom, from which 208,757 new users of SGLT2 inhibitors were propensity-matched 1:1 to new dipeptidyl peptidase-4 (DPP-4) inhibitor users.
Of those taking an SGLT2 inhibitor, 42.3% took canagliflozin, 30.7% dapagliflozin (Farxiga/Forxiga, AstraZeneca), and 27.0% empagliflozin (Jardiance, Boehringer Ingelheim).
Over a mean 0.9-year follow-up, 521 patients were hospitalized with DKA, for an overall incidence rate of 1.41 per 1,000 person-years.
The rate with SGLT2 inhibitors, 2.03 per 1,000 person-years, was nearly three times that seen with DPP-4 inhibitors, at 0.75 per 1,000 person-years, a significant difference (hazard ratio, 2.85).
By individual SGLT2 inhibitor, the hazard ratios compared with DPP-4 inhibitors were 1.86 for dapagliflozin, 2.52 for empagliflozin, and 3.58 for canagliflozin, all statistically significant. Stratification by age, sex, and incident versus prevalent user did not change the association between SGLT2 inhibitors and DKA.
Asked about the higher rate for canagliflozin, Dr. Taylor commented: “It is hard to know whether there are real and reproducible differences in the risks of DKA among the various SGLT2 inhibitors. The differences are not huge and the populations are not well matched.”
But, he noted, “If canagliflozin triggers more glucosuria, it is not surprising that it would also induce more ketosis and possibly ketoacidosis.”
He also noted that the threefold relative increase in DKA with canagliflozin versus comparators is consistent with Janssen’s data, published in 2015.
“It is, of course, reassuring that both [randomized clinical trials] and epidemiology produce similar estimates of the risk of drug-induced adverse events. Interestingly, the incidence of DKA is approximately threefold higher in the Canadian [data] as compared to Janssen’s clinical trials.”
Dr. Taylor also pointed out that, in the Janssen studies, the risk of canagliflozin-induced DKA appeared to be higher among patients with anti-islet antibodies, which suggests that some may have actually had autoimmune (type 1) diabetes. “So the overall risk of SGLT2 inhibitor-induced DKA may depend at least in part on the mix of patients.”
In the current study, individuals who never used insulin had a greater relative increase in risk of DKA with SGLT2 inhibitors, compared with DPP-4 inhibitors, than did those who did use insulin (hazard ratios, 3.96 vs. 2.24, both compared with DPP-4 inhibitors). However, just among those taking SGLT2 inhibitors, the absolute risk for DKA was higher for those with prior insulin use (3.52 vs. 1.43 per 1,000 person-years).
The results of sensitivity analyses were consistent with those of the primary analysis.
The study was funded by the Canadian Institutes of Health Research and supported by ICES. Dr. Douros has reported receiving a salary support award from Fonds de recherche du Quebec – sante. Dr. Taylor was previously employed at Bristol-Myers Squibb. He is currently a consultant for Ionis Pharmaceuticals and has reported receiving research support provided to the University of Maryland School of Medicine by Regeneron.

The rate with SGLT2 inhibitors, 2.03 per 1,000 person-years, was nearly three times that seen with DPP-4 inhibitors, at 0.75 per 1,000 person-years, a significant difference (hazard ratio, 2.85).
By individual SGLT2 inhibitor, the hazard ratios compared with DPP-4 inhibitors were 1.86 for dapagliflozin, 2.52 for empagliflozin, and 3.58 for canagliflozin, all statistically significant. Stratification by age, sex, and incident versus prevalent user did not change the association between SGLT2 inhibitors and DKA.
Asked about the higher rate for canagliflozin, Dr. Taylor commented: “It is hard to know whether there are real and reproducible differences in the risks of DKA among the various SGLT2 inhibitors. The differences are not huge and the populations are not well matched.”
But, he noted, “If canagliflozin triggers more glucosuria, it is not surprising that it would also induce more ketosis and possibly ketoacidosis.”
He also noted that the threefold relative increase in DKA with canagliflozin versus comparators is consistent with Janssen’s data, published in 2015.
“It is, of course, reassuring that both [randomized clinical trials] and epidemiology produce similar estimates of the risk of drug-induced adverse events. Interestingly, the incidence of DKA is approximately threefold higher in the Canadian [data] as compared to Janssen’s clinical trials.”
Dr. Taylor also pointed out that, in the Janssen studies, the risk of canagliflozin-induced DKA appeared to be higher among patients with anti-islet antibodies, which suggests that some may have actually had autoimmune (type 1) diabetes. “So the overall risk of SGLT2 inhibitor-induced DKA may depend at least in part on the mix of patients.”
In the current study, individuals who never used insulin had a greater relative increase in risk of DKA with SGLT2 inhibitors, compared with DPP-4 inhibitors, than did those who did use insulin (hazard ratios, 3.96 vs. 2.24, both compared with DPP-4 inhibitors). However, just among those taking SGLT2 inhibitors, the absolute risk for DKA was higher for those with prior insulin use (3.52 vs. 1.43 per 1,000 person-years).
The results of sensitivity analyses were consistent with those of the primary analysis.
The study was funded by the Canadian Institutes of Health Research and supported by ICES. Dr. Douros has reported receiving a salary support award from Fonds de recherche du Quebec – sante. Dr. Taylor was previously employed at Bristol-Myers Squibb. He is currently a consultant for Ionis Pharmaceuticals and has reported receiving research support provided to the University of Maryland School of Medicine by Regeneron.

according to a new large database analysis.
The findings, which include data on the use of three different SGLT2 inhibitors in Canada and the United Kingdom and suggest a class effect, were published online July 27 in Annals of Internal Medicine by Antonios Douros, MD, PhD, of McGill University and the Centre for Clinical Epidemiology, Lady Davis Institute, Montreal, and colleagues.
“Our results provide robust evidence that SGLT2 inhibitors are associated with an increased risk for DKA. Of note, increased risks were observed in all molecule-specific analyses, with canagliflozin [Invokana, Janssen] showing the highest effect estimate,” they noted.
And because the beneficial effects of SGLT2 inhibitors in the prevention of cardiovascular and renal disease will probably increase their uptake in the coming years, “Physicians should be aware of DKA as a potential adverse effect,” Dr. Douros and colleagues wrote.
Analysis “generally confirms what has already been published”
Asked for comment, Simeon I. Taylor, MD, PhD, professor of medicine at the University of Maryland, Baltimore, said that the study “generally confirms what has already been published” on the topic. He noted that overall “the risk of SGLT2 inhibitor–induced ketoacidosis is quite low in type 2 diabetes, perhaps on the order of 1 episode per 1000 patient-years.”
However, Dr. Taylor cautioned: “Published evidence suggests that the risk of DKA is increased if patients are unable to eat,” such as when hospitalized patients are not permitted to eat.
“In that setting, it is probably prudent to discontinue an SGLT2 inhibitor. Also, it may be prudent not to prescribe SGLT2 inhibitors to patients with a history of DKA,” he added.
Dr. Taylor also advised: “Although not necessarily supported by this publication, I think that caution should be exercised in prescribing SGLT2 inhibitors to insulin-dependent type 2 diabetes patients. ... Some late-stage type 2 diabetes patients may have severe insulin deficiency, and their physiology may resemble that of a type 1 diabetes patient.”
Dr. Taylor has previously advised against using SGLT2 inhibitors altogether in patients with type 1 diabetes.
Increased DKA risk seen across all SGLT2 inhibitors
The study involved electronic health care databases from seven Canadian provinces and the United Kingdom, from which 208,757 new users of SGLT2 inhibitors were propensity-matched 1:1 to new dipeptidyl peptidase-4 (DPP-4) inhibitor users.
Of those taking an SGLT2 inhibitor, 42.3% took canagliflozin, 30.7% dapagliflozin (Farxiga/Forxiga, AstraZeneca), and 27.0% empagliflozin (Jardiance, Boehringer Ingelheim).

FDA okays new CAR T therapy, first for mantle cell lymphoma
The Food and Drug Administration granted accelerated approval to brexucabtagene autoleucel (Tecartus, Kite Pharma), the first approved chimeric antigen receptor (CAR) T cell therapy for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL).
The new agent is the second approved CAR T cell product developed by Kite and follows the 2017 approval of axicabtagene ciloleucel (Yescarta) for diffuse large B-cell lymphoma.
“Despite promising advances, there are still major gaps in treatment for patients with MCL who progress following initial therapy,” investigator Michael Wang, MD, of the University of Texas MD Anderson Cancer Center in Houston, said in a company statement. “Many patients have high-risk disease and are more likely to keep progressing, even after subsequent treatments.”
In the same press statement, Meghan Gutierrez, chief executive officer, Lymphoma Research Foundation, said: “This approval marks the first CAR T cell therapy approved for mantle cell lymphoma patients and represents a new frontier in the treatment of this disease.”
The approval of the single-infusion therapy is based on efficacy and safety data from the ongoing, single-arm ZUMA-2 pivotal trial, which enrolled 74 adult patients. All patients had previously received anthracycline- or bendamustine-containing chemotherapy, an anti-CD20 antibody therapy and a Bruton tyrosine kinase inhibitor (ibrutinib or acalabrutinib).
In the trial, there was an objective response rate, which was the primary outcome measure, of 87% among 60 patients who were evaluable for efficacy analysis; 62% had a complete response.
Among all patients, follow-up was at least 6 months after their first objective disease response. Median duration of response has not yet been reached.
In terms of adverse events, 18% of the 82 patients evaluable for safety experienced > grade 3 cytokine release syndrome and 37% experienced neurologic events, per the company statement. The most common (≥ 10%) grade 3 or higher adverse reactions were anemia, neutropenia, thrombocytopenia, hypotension, hypophosphatemia, encephalopathy, leukopenia, hypoxia, pyrexia, hyponatremia, hypertension, infection-pathogen unspecified, pneumonia, hypocalcemia, and lymphopenia.
Brexucabtagene autoleucel will be manufactured in Kite’s facility in California. In the pivotal trial, there was a 96% manufacturing success rate and a median manufacturing turnaround time of 15 days from leukapheresis to product delivery.

Hypertension medication adjustment less likely with polypill
A secondary analysis of a major study of polypill therapy for hypertension found that patients who don’t reach blood pressure targets are less likely to have their medications adjusted if they’re on fixed-dose combination therapy.
However, hypertension patients on low-dose, triple-pill combination therapy are more likely to achieve blood pressure control than are those on usual care.
The secondary analysis of Triple Pill vs. Usual Care Management for Patients with Mild-to-Moderate Hypertension (TRIUMPH) was published online in JAMA Cardiology (2020 Jul 22. doi: 10.1001/jamacardio.2020.2739). The trial randomized 700 patients with hypertension in Sri Lanka to triple-pill fixed-dose combination (FDC) therapy or usual care during February 2016–May 2017, with follow-up ending in October 2017.
A greater proportion of FDC patients reached target BP by the end of the study compared with usual care, 70% vs. 55%. However, the study found that therapeutic inertia – the failure to intensify therapy in nonresponsive patients – was more common in the FDC group at 6- and 12-week follow-up: 87% vs. 64% and 90% vs. 65%, respectively; both differences were significant different at P < .001).
The once-daily FDC pill contained telmisartan 20 mg, amlodipine 2.5 mg; and chlorthalidone 12.5 mg.
“Using a triple low-dose combination blood-pressure pill reduced the need to uptitrate BP therapy as more patients are at target, but doctors were less likely to uptitrate with triple-pill therapy when it was needed,” lead author Nelson Wang, MD, a research fellow at the George Institute for Global Health in suburban Sydney, said in an interview.
“Overall, there were fewer treatment inertia episodes in the triple-pill group than in the usual care group, but this was driven by the fact that fewer triple-pill patients needed uptitration when coming to their follow-up visits,” Dr. Wang added.
The analysis found that clinicians who prescribed triple-pill FDC used 23 unique drug treatment regimens per 100 treated patients compared with 54 different regiments with usual care (P < .001). “There was a large simplification in care,” Dr. Wang said of the FDC approach.
Dr. Wang and colleagues called for greater efforts to address therapeutic inertia, particularly with FDC therapies, and suggested potential strategies consisting of patient education, incentives for appropriate treatment adjustments, and feedback mechanisms and reminders for physicians.
“There may also be a need for more dosage options with the FDC triple pill to allow physicians to intensify therapy without fear of overtreatment and adverse drug effects,” they wrote.
In an accompanying editorial (JAMA Cardiol. 2020 Jul 22. doi: 10.1001/jamacardio.2020.2693), Ann Marie Navar, MD, PhD, associate professor of cardiology at Duke Clinical Research Institute, Durham, N.C., noted that initiating treatment with FDC therapy doesn’t preclude a more personalized approach for patients who don’t achieve their BP target. “The real choice now is the choice of initial treatment,” she wrote, adding that future treatment guidelines should consider extending an FDC-first approach to patients with less severe levels of hypertension.
“The study showed there’s room for a both a population-based fixed-drug combination approach and a personalized approach to how we think about hypertension management with fixed-dose therapy,” she said in an interview. “It’s not a one-and-done situation.”

Levothyroxine: No LV benefit in subclinical hypothyroidism with MI
For patients with acute myocardial infarction (MI) and mild subclinical hypothyroidism (SCH), treatment with levothyroxine does not improve left ventricular function, according to results of the Thyroid in Acute Myocardial Infarction (ThyrAMI-2) trial.
“SCH is common, affecting approximately 10% of the adult population, and has been associated with worse outcomes in patients with cardiovascular disease in observational studies,” Salman Razvi, MD, Translational and Clinical Research Institute, Newcastle University, Newcastle upon Tyne, England, said in an interview.
This study shows that levothyroxine treatment for patients with SCH and acute MI is “unlikely to be of benefit,” he said.
“This study says that treating the thyroid failure does not help nor harm such patients,” Terry F. Davies, MD, director, division of endocrinology, diabetes, and bone diseases, Mount Sinai Beth Israel Medical Center, New York, said in an interview. He was not involved in the study, which was published online July 21 in JAMA.
Participants included 95 adults (mean age, 63.5 years; 72 men) with persistent mild SCH who presented with acute MI at six hospitals in the United Kingdom. Most (69%) had ST-segment elevation MI.
Inclusion criteria were age older than 18 years and serum thyrotropin level >4.0 mU/L with a normal free thyroxine level on two occasions 7-10 days apart and with one thyrotropin value <10 mU/L.
Forty-six participants were randomly allocated to receive levothyroxine starting at 25 mcg titrated to aim for serum thyrotropin levels between 0.4 and 2.5 mU/L and 49 to matching placebo capsules taken once daily for 52 weeks.
The primary outcome was left ventricular ejection fraction (LVEF) at 52 weeks, assessed via MRI, with adjustment for age, sex, acute MI type, affected coronary artery territory, and baseline LVEF.
Secondary outcomes were LV volume, infarct size, adverse events, and patient-reported outcome measures of health status, health-related quality of life, and depression.
The median daily dose of levothyroxine at the end of the study was 50 mcg. Adherence to study medication was 94% during the course of the study.
At week 52, mean LVEF improved from 51.3% at baseline to 53.8% in the levothyroxine group and from 54.0% to 56.1% in the placebo group.
The difference was not significant between groups, with an adjusted between-group difference of 0.76% (95% confidence interval, –0.93% to 2.46%; P = .37).
There were also no significant differences in any of the secondary outcomes. There were 15 (33.3%) cardiovascular adverse events in the levothyroxine group and 18 (36.7%) in the placebo group.
Recent clinical practice guidelines have highlighted a lack of high-quality data to make recommendations regarding the management of mild SCH, particularly for patients with cardiovascular disease, Dr. Razvi and colleagues noted in their article.
“On the basis of these findings, screening for and subsequent treatment of subclinical hypothyroidism in patients with acute myocardial infarction to preserve LV function is not justified,” they concluded.
Important caveats
The investigators noted several important caveats and limitations. The trial recruited patients with mild SCH because this group constitutes the majority of patients with SCH and for whom there is the “greatest uncertainty” regarding treatment efficacy. It’s not known whether targeting treatment for individuals with more severe disease may be beneficial.
The therapeutic benefit of levothyroxine may have been blunted, owing to the delay between coronary occlusion and the start of levothyroxine (median delay, 17 days). It’s unclear whether earlier treatment or treatment for a longer period may be beneficial.
But Dr. Davies noted that “treatment is usually avoided in the emergency situation,” and therefore he doesn’t think the treatment delay is a limitation; rather, “it would appear prudent,” he said in the interview.
“The real issues with an otherwise very careful study is the small size of the population despite the statistical assessment that this was all that was needed and, secondly, the small dose of thyroxine used,” Dr. Davies said.
The authors agree that the low dose of levothyroxine is a limitation. The median dose at the end of the study – 50 mcg daily – is “lower than that used in other trials that have demonstrated a benefit of treatment on endothelial function and lipid profiles,” they pointed out.
Dr. Davies noted that thyroid tests are “usually routine” for patients with MI. “Mild subclinical thyroid failure has been associated with worse cardiac outcomes, [but] treating such patients with thyroid hormone is very controversial since thyroid hormone can induce arrhythmias,” he said.
The study was supported in part by the National Institute for Health Research (NIHR) at the University of Leeds. Dr. Razvi received grants from the NIHR and nonfinancial support from Amdipharm Pharmaceuticals UK during the conduct of the study and personal fees from Merck and Abbott Pharmaceuticals outside the submitted work. Dr. Davies has disclosed no relevant financial relationships.

Inclusion criteria were age older than 18 years and serum thyrotropin level >4.0 mU/L with a normal free thyroxine level on two occasions 7-10 days apart and with one thyrotropin value <10 mU/L.
Forty-six participants were randomly allocated to receive levothyroxine starting at 25 mcg titrated to aim for serum thyrotropin levels between 0.4 and 2.5 mU/L and 49 to matching placebo capsules taken once daily for 52 weeks.
The primary outcome was left ventricular ejection fraction (LVEF) at 52 weeks, assessed via MRI, with adjustment for age, sex, acute MI type, affected coronary artery territory, and baseline LVEF.
Secondary outcomes were LV volume, infarct size, adverse events, and patient-reported outcome measures of health status, health-related quality of life, and depression.
The median daily dose of levothyroxine at the end of the study was 50 mcg. Adherence to study medication was 94% during the course of the study.
At week 52, mean LVEF improved from 51.3% at baseline to 53.8% in the levothyroxine group and from 54.0% to 56.1% in the placebo group.
The difference was not significant between groups, with an adjusted between-group difference of 0.76% (95% confidence interval, –0.93% to 2.46%; P = .37).
There were also no significant differences in any of the secondary outcomes. There were 15 (33.3%) cardiovascular adverse events in the levothyroxine group and 18 (36.7%) in the placebo group.
Recent clinical practice guidelines have highlighted a lack of high-quality data to make recommendations regarding the management of mild SCH, particularly for patients with cardiovascular disease, Dr. Razvi and colleagues noted in their article.
“On the basis of these findings, screening for and subsequent treatment of subclinical hypothyroidism in patients with acute myocardial infarction to preserve LV function is not justified,” they concluded.
Important caveats
The investigators noted several important caveats and limitations. The trial recruited patients with mild SCH because this group constitutes the majority of patients with SCH and for whom there is the “greatest uncertainty” regarding treatment efficacy. It’s not known whether targeting treatment for individuals with more severe disease may be beneficial.
The therapeutic benefit of levothyroxine may have been blunted, owing to the delay between coronary occlusion and the start of levothyroxine (median delay, 17 days). It’s unclear whether earlier treatment or treatment for a longer period may be beneficial.
But Dr. Davies noted that “treatment is usually avoided in the emergency situation,” and therefore he doesn’t think the treatment delay is a limitation; rather, “it would appear prudent,” he said in the interview.
“The real issues with an otherwise very careful study is the small size of the population despite the statistical assessment that this was all that was needed and, secondly, the small dose of thyroxine used,” Dr. Davies said.
The authors agree that the low dose of levothyroxine is a limitation. The median dose at the end of the study – 50 mcg daily – is “lower than that used in other trials that have demonstrated a benefit of treatment on endothelial function and lipid profiles,” they pointed out.
Dr. Davies noted that thyroid tests are “usually routine” for patients with MI. “Mild subclinical thyroid failure has been associated with worse cardiac outcomes, [but] treating such patients with thyroid hormone is very controversial since thyroid hormone can induce arrhythmias,” he said.
The study was supported in part by the National Institute for Health Research (NIHR) at the University of Leeds. Dr. Razvi received grants from the NIHR and nonfinancial support from Amdipharm Pharmaceuticals UK during the conduct of the study and personal fees from Merck and Abbott Pharmaceuticals outside the submitted work. Dr. Davies has disclosed no relevant financial relationships.

For patients with acute myocardial infarction (MI) and mild subclinical hypothyroidism (SCH), treatment with levothyroxine does not improve left ventricular function, according to results of the Thyroid in Acute Myocardial Infarction (ThyrAMI-2) trial.
“SCH is common, affecting approximately 10% of the adult population, and has been associated with worse outcomes in patients with cardiovascular disease in observational studies,” Salman Razvi, MD, Translational and Clinical Research Institute, Newcastle University, Newcastle upon Tyne, England, said in an interview.
This study shows that levothyroxine treatment for patients with SCH and acute MI is “unlikely to be of benefit,” he said.
“This study says that treating the thyroid failure does not help nor harm such patients,” Terry F. Davies, MD, director, division of endocrinology, diabetes, and bone diseases, Mount Sinai Beth Israel Medical Center, New York, said in an interview. He was not involved in the study, which was published online July 21 in JAMA.
