Renal function should be considered when determining whether to pick ticagrelor-aspirin or clopidogrel-aspirin as the antiplatelet therapy for patients with minor stroke, according to new research.

The study, which was conducted in 202 centers in China and published in Annals of Internal Medicine, indicates that when patients had normal kidney function, ticagrelor-aspirin, compared with clopidogrel-aspirin, substantially reduced the risk for recurrent stroke within 90 days of follow-up.

However, this effect was not seen in patients with mildly, moderately or severely decreased kidney function.

Rates of severe or moderate bleeding did not differ substantially between the two treatments.
 

Results gleaned from CHANCE-2 data

The researchers, led by Anxin Wang, PhD, from Capital Medical University in Beijing, conducted a post hoc analysis of the CHANCE-2 (Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events-II) trial.

The trial included 6,378 patients who carried cytochrome P450 2C19 (CYP2C19) loss-of-function (LOF) alleles who had experienced a minor stroke or transient ischemic attack.

Patients received either ticagrelor-aspirin or clopidogrel-aspirin, and their renal function was measured by estimated glomerular filtration rate. The authors listed as a limitation that no data were available on the presence of albuminuria or proteinuria.

The researchers investigated what effect renal function had on the efficacy and safety of the therapies.
 

Differences in the therapies

Clopidogrel-aspirin is often recommended for preventing stroke. It can reduce thrombotic risk in patients with impaired kidney function, the authors noted. Ticagrelor can provide greater, faster, and more consistent P2Y12 inhibition than clopidogrel, and evidence shows it is effective in preventing stroke recurrence, particularly in people carrying CYP2C19 LOF alleles.

When people have reduced kidney function, clopidogrel may be harder to clear than ticagrelor and there may be increased plasma concentrations, so function is important to consider when choosing an antiplatelet therapy, the authors wrote.
 

Choice may come down to cost

Geoffrey Barnes, MD, MSc, associate professor of vascular and cardiovascular medicine at University of Michigan Medicine in Ann Arbor, said in an interview that there has been momentum toward ticagrelor as a more potent choice than clopidogrel not just in populations with minor stroke but for people with MI and coronary stents.

He said he found the results surprising and was intrigued that this paper suggests looking more skeptically at ticagrelor when kidney function is impaired.

Still, the choice may also come down to what the patient can afford at the pharmacy, he said.

“The reality is many patients still get clopidogrel either because that’s what their physicians have been prescribing for well over a decade or because of cost issues, and clopidogrel, for many patients, can be less expensive,” Dr. Barnes noted.

He said he would like to see more study in different populations as the prevalence of people carrying CYP2C19 allele differs by race and results might be different in a non-Asian population. That allele is thought to affect how clopidogrel is metabolized.
 

Study should spur more research

Nada El Husseini, MD, associate professor of neurology and Duke Telestroke Medical Director at Duke University Medical Center, Durham, N.C., said the study is hypothesis generating, but shouldn’t be thought of as the last word on the subject.

She pointed out some additional limitations of the study, including that it was a post hoc analysis. She explained that the question researchers asked in this study – about effect of kidney function on the safety and efficacy of the therapies – was not the focus of the original CHANCE-2 study, and, as such, the post hoc study may have been underpowered to answer the renal function question.

The authors acknowledged that limitation, noting that “the proportion of patients with severely decreased renal function was low.”

Among 6,378 patients, 4,050 (63.5%) had normal kidney function, 2,010 (31.5%) had mildly decreased function, and 318 (5.0%) had moderately to severely decreased function.

The study was funded by the Ministry of Science and Technology of the People’s Republic of China, the Beijing Municipal Science and Technology Commission, the Chinese Stroke Association, the National Science and Technology Major Project and the Beijing Municipal Administration of Hospitals Incubating Program). Salubris Pharmaceuticals contributed ticagrelor and, clopidogrel at no cost and with no restrictions. Dr. Wang reported no relevant financial relationships. Dr. Barnes and Dr. El Husseini reported no relevant financial relationships.

The effectiveness of up to three doses of COVID-19 vaccine was moderate overall and significantly lower among individuals with immunocompromising conditions, compared with the general population during the period of Omicron dominance, according to an analysis of data from more than 34,000 hospitalizations.

Previous studies have suggested lower COVID-19 vaccine effectiveness among immunocompromised individuals, compared with healthy individuals from the general population, but data from the period in which Omicron subvariants have been dominant are limited, wrote Amadea Britton, MD, of the Centers for Disease Control and Prevention’s COVID-19 Emergency Response Team, and colleagues.

The CDC currently recommends an expanded primary vaccine series of three doses of an mRNA vaccine, and the Advisory Committee on Immunization Practices has recommended a fourth dose with the new bivalent booster that contains elements of the Omicron variant, the researchers noted.

In a study published in the CDC’s Morbidity and Mortality Weekly Report, the researchers identified 34,220 adults with immunocompromising conditions who were hospitalized for COVID-19–like illness between Dec. 16, 2021, and Aug. 20, 2022. These conditions included solid malignancy (40.5%), hematologic malignancy (14.6%), rheumatologic or inflammatory disorder (24.4%), other intrinsic immune condition or immunodeficiency (38.5%), or organ or stem cell transplant (8.6%). They used data from the CDC’s VISION Network, a multistate database. The data include spring and summer 2022, when the BA.4 and BA.5 Omicron subvariants dominated other strains, and adults with immunocompromising conditions were eligible for a total of four vaccine doses (two primary doses and two boosters). The median age of the study population was 69 years, and 25.7%, 41.7%, and 7.0% had received two, three, and four doses, respectively, of COVID-19 vaccine.

Overall, vaccine effectiveness (VE) among immunocompromised patients was 34% after two vaccine doses, increasing to 71% during days 7-89 after a third dose, then declining to 41% 90 days or more after that dose.

During the full Omicron period, VE was 36% for 14 or more days after dose two, 69% for 7-89 days after dose three, and 44% for 90 or more days after dose three.

When VE was stratified by sublineage period, VE was higher 7 or more days after dose three during the predominance of BA.1 (67%), compared with VE during the dominant periods of BA.2/BA.2.12.1 (32%) and BA.4/BA.5 (35%).

In the later periods when Omicron BA.2/BA.2.12.1 and BA.4/BA.5 variants dominated, and individuals who had received three doses of vaccine were eligible for a fourth, VE against these variants was 32% 90 or more days after dose three and 43% 7 or more days after dose four.

VE was lowest among individuals with potentially more severe immunocompromising conditions, notably solid organ or stem cell transplants, the researchers wrote in their discussion.

The study findings were limited by several factors including the use of ICD-9 and -10 discharge diagnosis codes for immunocompromising conditions, potential confounding in VE models, lack of data on outpatient treatments such as nirmatelvir/ritonavir (Paxlovid), and lack of COVID-19 genomic sequencing data that may have affected which sublineage was identified, the researchers noted.

However, “this study confirms that even with boosters, immunocompromised adults, because of their weakened immune systems, are still at high risk of moderate to severe COVID,” said coauthor Brian Dixon, PhD, of the Regenstrief Institute and Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, in a press release about the study.

“Given the incomplete protection against hospitalization afforded by monovalent COVID-19 vaccines, persons with immunocompromising conditions might benefit from updated bivalent vaccine booster doses that target recently circulating Omicron sublineages, in line with ACIP [Advisory Committee on Immunization Practices] recommendations,” the researchers concluded in the study.

The study was funded by the CDC. The researchers had no financial conflicts to disclose. The VISION Network is a collaboration between the CDC, the Regenstrief Institute, and seven health care systems across the United States: Columbia University Irving Medical Center (New York), HealthPartners (Wisconsin), Intermountain Healthcare (Utah), Kaiser Permanente Northern California, Kaiser Permanente Northwest (Washington State), the University of Colorado, and Paso Del Norte Health Information Exchange (Texas).

Acupuncture is a very popular treatment strategy in some areas of the world and is extensively applied in Chinese practice. Though this is a regularly applied treatment, a direct comparison with first-line antispasmodics has not been previously completed. The study by Shi and colleagues sought to compare the treatment of IBS using an adjusted indirect treatment comparison meta-analysis. This study proves that cimetropium was the most effective for relieving abdominal pain, whereas drotaverine, acupuncture, and pinaverium remained superior to the placebo. That being said, acupuncture was shown to be superior in relieving global IBS symptoms and caused fewer side effects than did antispasmodics. This shows that acupuncture may have a role in the treatment algorithm for IBS even outside of China, where it is used broadly.

The study by Formica and colleagues provides new insights on the etiology and pathogenesis of IBS. These insights include the positive correlation between disgust sensitivity and IBS quality of life (QOL) scores. The relationship between IBS and the emotional intensity of the experience of disgust is discussed throughout this study and more severe IBS-QOL scores were linked to those with high levels of disgust sensitivity. This study had gender limitations because of the low number of male participants, so these correlations were patterned mostly in female participants.

A new study based on U.S. veterans’ medical records adds to the evidence for a link between gout – especially poorly controlled cases – and cardiovascular disease (CVD) risk, Tate Johnson, MD, reported at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network.

Gout was associated with a 68% increased risk of heart failure (HF) hospitalization, 25% increased risk of HF-related death, and a 22% increased risk of major adverse cardiovascular events (MACE), said Dr. Johnson, of the division of rheumatology at the University of Nebraska, Omaha.

Poorly controlled serum urate was associated with a higher risk of cardiovascular events, regardless of the use of urate-lowering therapy (ULT). He said more research is needed to see if there is a causal link between gout, hyperuricemia – or its treatment – and CVD risk.

Dr. Johnson and colleagues used records from the Veterans Health Administration for this study. They created a retrospective, matched cohort study that looked at records dating from January 1999 to September 2015. Patients with gout (≥ 2 ICD-9 codes) were matched 1:10 on age, sex, and year of VHA enrollment to patients without a gout ICD-9 code or a record of receiving ULT. They matched 559,243 people with gout to 5,407,379 people who did not have a diagnosis or a recorded treatment for this condition.

Over 43,331,604 person-years, Dr. Johnson and colleagues observed 137,162 CVD events in gout (incidence rate 33.96 per 1,000 person-years) vs. 879,903 in non-gout patients (IR 22.37 per 1,000 person-years). Gout was most strongly associated with HF hospitalization, with a nearly threefold higher risk (hazard ratio, 2.78; 95% confidence interval, 2.73-2.83), which attenuated but persisted after adjustment for additional CVD risk factors (adjusted hazard ratio, 1.68; 95% CI, 1.65-1.70) and excluding patients with prevalent HF (aHR, 1.60; 95% CI, 1.57-1.64).

People with gout were also at higher risk of HF-related death (aHR, 1.25; 95% CI, 1.21-1.29), MACE (aHR, 1.22; 95% CI, 1.21-1.23), and coronary artery disease–related death (aHR, 1.21; 95% CI, 1.20-1.22).

Among people with gout in the study, poor serum urate control was associated with a higher risk of all CVD events, with the highest CVD risk occurring in patients with inadequately controlled serum urate despite receipt of ULT, particularly related to HF hospitalization (aHR, 1.43; 95% CI, 1.34-1.52) and HF-related death (aHR, 1.47; 95% CI, 1.34-1.61).

Limits of the study include the generalizability of the study population. Reflecting the VHA’s patient population, 99% of the cohort were men, with 62% of the gout group and 59.4% of the control group identifying as White and non-Hispanic.

The study provides evidence that may be found only by studying medical records, Richard J. Johnson, MD, of the University of Colorado at Denver, Aurora, said in an interview.

Dr. Richard Johnson, who is not related to the author, said that only about one-third of people with gout are adequately treated, and about another one-third take urate-lowering therapy (ULT) but fail to get their serum urate level under control. But it would be unethical to design a clinical trial to study CVD risk and poorly controlled serum urate without ULT treatment.

“The only way you can figure out if uric acid lowering is going to help these guys is to actually do a study like this where you see the ones who don’t get adequate treatment versus adequate treatment and you show that there’s going to be a difference in outcome,” he said.

Dr. Richard Johnson contrasted this approach with the one used in the recently reported study that appeared to cast doubt on the link between serum uric acid levels and cardiovascular disease. The ALL-HEART trial found that allopurinol, a drug commonly used to treat gout, provided no benefit in terms of reducing cardiovascular events in patients with ischemic heart disease. But these patients did not have gout, and that was a critical difference, he said.

He noted that it was not surprising that the results of ALL-HEART were negative, given the study design.

“The ALL-HEART study treated people regardless of their uric acid level, and they also excluded subjects who had a history of gout,” he said. “Yet the risk associated with uric acid occurs primarily among those with elevated serum uric acid levels and those with gout.”

The study received funding from the Rheumatology Research Foundation and the VHA. Neither Dr. Tate Johnson nor Dr. Richard Johnson had any relevant disclosures.

A new study based on U.S. veterans’ medical records adds to the evidence for a link between gout – especially poorly controlled cases – and cardiovascular disease (CVD) risk, Tate Johnson, MD, reported at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network.

Gout was associated with a 68% increased risk of heart failure (HF) hospitalization, 25% increased risk of HF-related death, and a 22% increased risk of major adverse cardiovascular events (MACE), said Dr. Johnson, of the division of rheumatology at the University of Nebraska, Omaha.

Poorly controlled serum urate was associated with a higher risk of cardiovascular events, regardless of the use of urate-lowering therapy (ULT). He said more research is needed to see if there is a causal link between gout, hyperuricemia – or its treatment – and CVD risk.

Dr. Johnson and colleagues used records from the Veterans Health Administration for this study. They created a retrospective, matched cohort study that looked at records dating from January 1999 to September 2015. Patients with gout (≥ 2 ICD-9 codes) were matched 1:10 on age, sex, and year of VHA enrollment to patients without a gout ICD-9 code or a record of receiving ULT. They matched 559,243 people with gout to 5,407,379 people who did not have a diagnosis or a recorded treatment for this condition.

Over 43,331,604 person-years, Dr. Johnson and colleagues observed 137,162 CVD events in gout (incidence rate 33.96 per 1,000 person-years) vs. 879,903 in non-gout patients (IR 22.37 per 1,000 person-years). Gout was most strongly associated with HF hospitalization, with a nearly threefold higher risk (hazard ratio, 2.78; 95% confidence interval, 2.73-2.83), which attenuated but persisted after adjustment for additional CVD risk factors (adjusted hazard ratio, 1.68; 95% CI, 1.65-1.70) and excluding patients with prevalent HF (aHR, 1.60; 95% CI, 1.57-1.64).

People with gout were also at higher risk of HF-related death (aHR, 1.25; 95% CI, 1.21-1.29), MACE (aHR, 1.22; 95% CI, 1.21-1.23), and coronary artery disease–related death (aHR, 1.21; 95% CI, 1.20-1.22).

Among people with gout in the study, poor serum urate control was associated with a higher risk of all CVD events, with the highest CVD risk occurring in patients with inadequately controlled serum urate despite receipt of ULT, particularly related to HF hospitalization (aHR, 1.43; 95% CI, 1.34-1.52) and HF-related death (aHR, 1.47; 95% CI, 1.34-1.61).

Limits of the study include the generalizability of the study population. Reflecting the VHA’s patient population, 99% of the cohort were men, with 62% of the gout group and 59.4% of the control group identifying as White and non-Hispanic.

The study provides evidence that may be found only by studying medical records, Richard J. Johnson, MD, of the University of Colorado at Denver, Aurora, said in an interview.

Dr. Richard Johnson, who is not related to the author, said that only about one-third of people with gout are adequately treated, and about another one-third take urate-lowering therapy (ULT) but fail to get their serum urate level under control. But it would be unethical to design a clinical trial to study CVD risk and poorly controlled serum urate without ULT treatment.

“The only way you can figure out if uric acid lowering is going to help these guys is to actually do a study like this where you see the ones who don’t get adequate treatment versus adequate treatment and you show that there’s going to be a difference in outcome,” he said.

Dupilumab appears to improve clinical, symptomatic, histologic, and endoscopic aspects of eosinophilic esophagitis (EoE) up to 24 weeks, according to findings presented at the annual meeting of the American College of Gastroenterology.

The drug was also well tolerated, demonstrating consistency with the known dupilumab safety profile, said Evan S. Dellon, MD, a gastroenterologist at the University of North Carolina at Chapel Hill.

In May, the Food and Drug Administration approved dupilumab (Dupixent) for the treatment of EoE in adults and adolescents who are 12 years and older and weigh at least 40 kg (about 88 pounds), based on safety and efficacy data previously presented by Dr. Dellon and colleagues as part of the phase 3 LIBERTY-EoE-TREET study (NCT03633617).

“Dupilumab is now the only medication FDA approved to treat EoE in the U.S.,” Dr. Dellon said. “The findings here are that the pooled efficacy and safety data for parts A and B of the phase 3 trial are consistent with the results of the individual parts of the study that were previously reported, and which led to the drug being approved for EoE.”

EoE is a chronic, progressive, type 2 inflammatory disease of the esophagus, which can lead to symptoms of esophageal dysfunction that affect quality of life. Current treatment options often lack specificity, present adherence challenges, and provide suboptimal long-term disease control, Dr. Dellon said.

Dupilumab, a fully human monoclonal antibody manufactured by Regeneron Pharmaceuticals, blocks the shared receptor component for interleukin-4 and IL-13, which are central drivers of type 2 inflammation in EoE.
 

Study population difficult to treat

In the three-part, double-blind, placebo-controlled, phase 3 study, dupilumab was administered to 122 patients as 300-mg weekly doses through subcutaneous injection. In parts A and B, dupilumab demonstrated statistically significant and clinically meaningful improvement in adults and adolescents up to 24 weeks. In patients from part A who continued to an extended active treatment period called part C, efficacy was sustained to week 52.

Participants were included if they had EoE that hadn’t responded to high-dose proton pump inhibitors, had baseline esophageal biopsies with a peak intraepithelial eosinophilic count of 15 eosinophils per high-power field (eos/HPF) or higher in two or more esophageal regions, had a history of an average of two or more episodes of dysphagia per week in the 4 weeks prior to screening, had four or more episodes of dysphagia in the 2 weeks prior to randomization with two or more episodes that required liquids or medical attention, and had a baseline Dysphagia Symptom Questionnaire (DSQ) score of 10 or higher.

On the other hand, participants were excluded if they initiated or changed a food-elimination diet regimen or reintroduced a previously eliminated food group in the 6 weeks before screening, had other causes of esophageal eosinophilia, had a history of other inflammatory diseases such as Crohn’s disease or ulcerative colitis, or were treated with swallowed topical corticosteroids within 8 weeks prior to baseline.

Dr. Dellon and colleagues focused on co–primary endpoints: The proportion of patients who achieved peak esophageal intraepithelial eosinophil count of 6 eos/HPF or less, and the absolute change in DSQ score from baseline to week 24.

Key secondary endpoints included percentage change in eos/HPF, absolute change in EoE-Endoscopic Reference Score (EREFS), absolute change in EoE-Histologic Scoring System (EoE-HSS) grade score, and EoE-HSS stage score. Other secondary endpoints included percentage change in DSQ score and proportion of patients achieving less than 15 eos/HPF.

The baseline demographics and clinical characteristics were similar between the treatment and placebo groups. Importantly, about 70% had been treated with topical corticosteroids, and about 40% had a history of esophageal dilation, Dr. Dellon said. The DSQ scores, peak eosinophil counts, and EREFS scores were high, indicating an inflamed, symptomatic, and difficult-to-treat population.
 

Pooled parts A and B findings

Overall, dupilumab reduced peak esophageal intraepithelial eosinophil counts at week 24. In the dupilumab group, 59% of patients were down to 6 eos/HPF or less, compared with 5.9% in the placebo group. In a secondary endpoint, 77% of dupilumab patients were down to 15 eos/HPF, compared with 7.6% in the placebo group. The dupilumab group saw an 80% drop in baseline change, compared with 1.5% in the placebo group.

Dupilumab also reduced dysphagia symptoms and improved endoscopic features of EoE at week 24. The absolute change in DSQ score was –23.21 in the dupilumab group, compared with –12.69 in the placebo group. The percent change in DSQ score was –65.5% in the dupilumab group, compared with –38.2% in the placebo group. The absolute change in EREFS score was –3.95 in the dupilumab group, compared with –0.41 in the placebo group.

In addition, dupilumab reduced histologic scores at week 24. The absolute change in EoE-HSS grade score was –0.82 in the dupilumab group, compared with –0.1 in the placebo group. The absolute change in EoE-HSS stage score was –0.79 in the dupilumab group, compared with –0.09 in the placebo group.

Dupilumab demonstrated an acceptable safety profile, and no new safety signals were noted, Dr. Dellon said. The most common adverse events was injection-site reaction at 37.5% in the dupilumab group and 33.3% in the placebo group. The severe adverse events were not related to the medication.

“If patients have EoE, dupilumab might be an option for treatment. However, it’s important to realize that, in the phase 3 study, all patients were PPI nonresponders, most had been treated with topical steroids [and many were not responsive], and many had prior esophageal dilation,” Dr. Dellon said. “We don’t have a lot of data in more mild EoE patients, and insurances are currently requiring a series of authorization before patients might be able to get this medication. It’s best to talk to their doctor about whether the medication is a good fit for not.”

The study was sponsored by Sanofi and Regeneron Pharmaceuticals. Three of the authors are employees for and have stock options with Regeneron or Sanofi. The other authors reported consultant roles, advisory roles, and research support from numerous pharmaceutical companies, including Regeneron and Sanofi.

MONTREAL – Patients hospitalized with severe COVID-19 and no prior history of thyroid dysfunction show signs of thyroiditis that, although asymptomatic, continue to persist for up to a year after infection, according to research that adds to evidence on the complex involvement of the thyroid in COVID-19.

“To our knowledge these findings are novel,” first author Ilaria Muller, MD, PhD, an assistant professor in endocrinology in the department of clinical sciences and community health, University of Milan, told this news organization.

“Little has been written about the long-term follow-up of thyroid function after severe COVID-19 disease, and we have followed patients up to 1 year after infection.”

The effects are seen in about 10%-15% of patients, and “[while] the thyroid dysfunction is transient, ultrasound areas of thyroiditis may persist after 1 year, even if they progressively shrink,” said Dr. Muller, who presented the findings at the American Thyroid Association annual meeting.
 

Immunological scars? Clinical implications unclear

The nature and implications of the persistent thyroiditis areas are uncertain, Dr. Muller noted. “These areas of thyroiditis are likely a sort of ‘immunologic scar’ of the previous SARS-CoV-2 infection,” she explained. “We still don’t know if there are clinical implications, even if they seem unlikely.”

Of note, increases in autoimmune processes or a higher incidence of thyroid dysfunction after COVID-19 have not been observed, and the shrinkage of the areas of thyroiditis over time is encouraging, she said.

The reasons why some patients develop atypical thyroiditis and others don’t are also unclear, with Dr. Muller’s team investigating further. Importantly, similar effects have been associated with other severe infections, not just COVID-19. “It is well known that in classic subacute thyroiditis due to other viral infections, the areas of thyroiditis persist for months, so this phenomenon might not be unique to COVID-19,” she explained.

Commenting on the story, Jeffrey R. Garber, MD, also noted that such thyroiditis areas stemming from other types of infection may persist – but go unnoticed.

“Resolution is the clinical rule, [and] we generally do not restudy in detail those who clinically recover,” he said in an interview. “However, there is evidence of impaired thyroid reserve in those who recover from viral thyroiditis due to other sources.”

“Thyroid symptoms are often not specific, so ‘atypical’ [cases] are common, [and] resolution with restoring thyroid status to normal is mixed,” noted Dr. Garber, an associate professor of medicine at Harvard Medical School and chief of the division of endocrinology at Atrius Health, Boston.

In terms of clinical practice, while such issues should be kept in mind when evaluating abnormal thyroid tests during severe COVID-19, “it is not a call for routinely checking it in the absence of clinical suspicion,” he observed.
 

Study details

Dr. Muller and her team previously observed that patients hospitalized in intensive care with COVID-19 often had low or suppressed serum thyroid-stimulating hormone (TSH) levels, with and without elevated free thyroxine (FT₄) concentrations, suggestive of thyrotoxicosis.

Upon investigating those cases, they found, as in their previous study reported by this news organization, that a painless, atypical thyroiditis occurs with nonthyroidal illness syndrome among patients hospitalized with severe COVID-19. The atypical thyroiditis was slightly more common in men and was associated with lymphopenia.

To further investigate those cases and follow patients up to 1 year, the team conducted a longitudinal study of 183 patients hospitalized with severe COVID-19 in Italy. The patients, who had no known prior history of thyroid dysfunction, were assessed for serum thyroid function, autoantibodies, and inflammatory markers.

At baseline, 10% of the patients were found to have thyrotoxicosis, and ultrasound performed within 2-3 months postinfection on 65 patients showed that 18 (28%) had areas of thyroiditis.

Importantly, 60% of those patients with the areas of thyroiditis had low TSH levels, while 25% had normal TSH levels (P = .034).

In addition, those showing the presence of thyroiditis on ultrasound at 23 months were more likely to have elevated serum concentrations of FT₄ (P = .018) and higher levels of interleukin-26 (P = .016), compared with those with normal ultrasound readings.

In a longitudinal analysis further following patients post infection, among 15 patients who were evaluated at 6 months, most, 13 (87%), still had areas of thyroiditis, and 6 of 12 (50%) had thyroiditis areas that, though reduced in size, still persisted even at 12 months.

In terms of thyroid uptake, at 3 months, 14 of 17 patients (82%) had diffused or focal areas of a reduction of uptake. After 6 months, there was a recovery, with a median of 28% of thyroid uptake recovered, however, 67% of patients still had some focal or diffused reduction in thyroid uptake.

Of note, the indications of thyroiditis on imaging persisted even though patients’ TSH levels had quickly normalized at the end of infection and remained normal up to 1 year of follow-up.

The patients showed no apparent development of thyroglobulin antibody, thyroid peroxidase antibodies, or TSH receptor antibodies.

A further fine needle aspiration analysis of eight patients with atypical thyroiditis at 3 months after infection showed that those patients had tissue resident memory T cells (CD4+/CD8+/CD103+/CD69+) within the thyroid, but not in the blood as expected.

Additional assessments at 8 months after infection showed those tissue resident memory T cells continued to be present on imaging.

The results showed “SARS-CoV-2–specific T cells were enriched within the thyroid compared with the blood, many with a tissue resident phenotype,” Dr. Muller explained.

The findings are notable in that “such an in-depth characterization of areas of thyroiditis triggered by SARS-CoV-2 infection combining ultrasound, scintigraphy, and immunological phenotyping has not been performed so far,” she said.

“In particular, SARS-CoV-2–specific tissue-resident memory T lymphocytes have not been described before in the thyroid gland.”

Dr. Muller and Dr. Garber have reported no relevant financial relationships.

MONTREAL – Patients hospitalized with severe COVID-19 and no prior history of thyroid dysfunction show signs of thyroiditis that, although asymptomatic, continue to persist for up to a year after infection, according to research that adds to evidence on the complex involvement of the thyroid in COVID-19.

“To our knowledge these findings are novel,” first author Ilaria Muller, MD, PhD, an assistant professor in endocrinology in the department of clinical sciences and community health, University of Milan, told this news organization.

“Little has been written about the long-term follow-up of thyroid function after severe COVID-19 disease, and we have followed patients up to 1 year after infection.”

The effects are seen in about 10%-15% of patients, and “[while] the thyroid dysfunction is transient, ultrasound areas of thyroiditis may persist after 1 year, even if they progressively shrink,” said Dr. Muller, who presented the findings at the American Thyroid Association annual meeting.
 

Immunological scars? Clinical implications unclear

The nature and implications of the persistent thyroiditis areas are uncertain, Dr. Muller noted. “These areas of thyroiditis are likely a sort of ‘immunologic scar’ of the previous SARS-CoV-2 infection,” she explained. “We still don’t know if there are clinical implications, even if they seem unlikely.”

Of note, increases in autoimmune processes or a higher incidence of thyroid dysfunction after COVID-19 have not been observed, and the shrinkage of the areas of thyroiditis over time is encouraging, she said.

The reasons why some patients develop atypical thyroiditis and others don’t are also unclear, with Dr. Muller’s team investigating further. Importantly, similar effects have been associated with other severe infections, not just COVID-19. “It is well known that in classic subacute thyroiditis due to other viral infections, the areas of thyroiditis persist for months, so this phenomenon might not be unique to COVID-19,” she explained.

Commenting on the story, Jeffrey R. Garber, MD, also noted that such thyroiditis areas stemming from other types of infection may persist – but go unnoticed.

“Resolution is the clinical rule, [and] we generally do not restudy in detail those who clinically recover,” he said in an interview. “However, there is evidence of impaired thyroid reserve in those who recover from viral thyroiditis due to other sources.”

“Thyroid symptoms are often not specific, so ‘atypical’ [cases] are common, [and] resolution with restoring thyroid status to normal is mixed,” noted Dr. Garber, an associate professor of medicine at Harvard Medical School and chief of the division of endocrinology at Atrius Health, Boston.

In terms of clinical practice, while such issues should be kept in mind when evaluating abnormal thyroid tests during severe COVID-19, “it is not a call for routinely checking it in the absence of clinical suspicion,” he observed.
 

Study details

Dr. Muller and her team previously observed that patients hospitalized in intensive care with COVID-19 often had low or suppressed serum thyroid-stimulating hormone (TSH) levels, with and without elevated free thyroxine (FT₄) concentrations, suggestive of thyrotoxicosis.

Upon investigating those cases, they found, as in their previous study reported by this news organization, that a painless, atypical thyroiditis occurs with nonthyroidal illness syndrome among patients hospitalized with severe COVID-19. The atypical thyroiditis was slightly more common in men and was associated with lymphopenia.

To further investigate those cases and follow patients up to 1 year, the team conducted a longitudinal study of 183 patients hospitalized with severe COVID-19 in Italy. The patients, who had no known prior history of thyroid dysfunction, were assessed for serum thyroid function, autoantibodies, and inflammatory markers.

At baseline, 10% of the patients were found to have thyrotoxicosis, and ultrasound performed within 2-3 months postinfection on 65 patients showed that 18 (28%) had areas of thyroiditis.

Comorbidities may play a greater role than genetics women with gout, although this appears not to be true for men, Nicholas Sumpter, MSc, of the University of Alabama at Birmingham said at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network (G-CAN).

Mr. Sumpter was among the authors of a recent paper in Arthritis & Rheumatology that suggested that earlier gout onset involves the accumulation of certain allelic variants in men. This genetic risk was shared across multiple ancestral groups in the study, conducted with men of European and Polynesian ancestry, Mr. Sumpter and colleagues reported.

“There might be more than one factor in gout in men, but in women we’ve been getting at this idea that comorbidities are the big thing,” he said.

During his presentation, Mr. Sumpter offered a hypothesis that in men there might be a kind of “two-pronged attack,” with increases in serum urate linked to genetic risk, but comorbidities also playing a role. “But that may not be the case for women.”

In his presentation, Mr. Sumpter noted a paper published in March 2022 from his University of Alabama at Birmingham colleagues, Aakash V. Patel, MD, and Angelo L. Gaffo, MD. In the article, Dr. Patel and Dr. Gaffo delved into the challenges of treating women with gout given “the paucity of appropriately well-powered, randomized-controlled trials investigating the efficacy” of commonly used treatments.

“This poses major challenges for the management of female gout patients since they carry a greater burden of cardiovascular and renal morbidity, which is known to modulate the pathophysiology of gout; as such, conclusions regarding the efficacy of treatments for females cannot be extrapolated from investigative studies that are predominantly male,” they wrote, calling for increased efforts to enroll women in studies of treatments for this condition.

There’s increased interest in how gout affects women, including findings in a paper published in September in Arthritis & Rheumatology that found people with gout, especially women, appear to be at higher risk for poor COVID-19 outcomes, including hospitalization and death, regardless of COVID-19 vaccination status.

Gout has become more common in women, although this remains a condition that is far more likely to strike men.

The age-standardized prevalence of gout among women rose from 233.52 per 100,000 in 1990 to 253.49 in 2017, a gain of about 9%, according to a systematic analysis of the Global Burden of Disease Study.

That topped the roughly 5% gain seen for men in the same time frame, with the rate going from 747.48 per 100,000 to 790.90. With the aging of the global population, gout’s burden in terms of prevalence and disability is expected to increase.

Impact of obesity and healthy eating patterns

Obesity, or excess adiposity, appears to be of particular concern for women in terms of gout risk.

While obesity and genetic predisposition both are strongly associated with a higher risk of gout, the excess risk of both combined was higher than the sum of each, particularly among women, Natalie McCormick, PhD, of Massachusetts General Hospital, Boston, and coauthors reported in Annals of the Rheumatic Diseases.

These findings suggested that “addressing excess adiposity could prevent a large proportion of female gout cases in particular, as well as its cardiometabolic comorbidities, and the benefit could be greater in genetically predisposed women,” they wrote.

In general, there’s a need to re-examine the advice given by many clinicians in the past that people with gout, or those at risk for it, should follow a low-protein diet to avoid purines, Dr. McCormick said in an interview.

“Now we’re finding that a healthier diet that balances protein as well as fat intake can actually be better both for cardiovascular health and for gout prevention,” she said.

Dr. McCormick’s research on this topic includes a 2022 JAMA Internal Medicine article, and a 2021 article in Current Rheumatology Reports. In the latter article, Dr. McCormick and colleagues examined the benefits of changing habits for patients, such as following one of several well-established healthy eating patterns, including the Mediterranean and DASH diets.

With excess weight and associated cardiovascular and endocrine risks already elevated among people with gout, especially women, the “conventional low-purine (i.e., low-protein) approach to gout dietary guidance is neither helpful nor sustainable and may lead to detrimental effects related to worsening insulin resistance as a result of substitution of healthy proteins with unhealthy carbohydrates or fats,” they wrote. “Rather, by focusing our dietary recommendations on healthy eating patterns which have been proven to reduce cardiometabolic risk factors, as opposed to singular ‘good’ or ‘bad’ food items or groups, the beneficial effects of such diets on relevant gout endpoints should naturally follow for the majority of typical gout cases, mediated through changes in insulin resistance.”

Mr. Sumpter and Dr. McCormick had no competing interests to declare.

Heart failure (HF) patients with high serum levels of alpha-linolenic acid (ALA) had a better prognosis than those with the lowest levels, in an observational study.

ALA is an omega-3 fatty acid that is found mainly in plants, including flaxseed, chia, walnuts, or canola oil.

PxHere

Plant power

Dr. Sala-Vila and colleagues analyzed data and samples from 905 patients (mean age, 67; 32% women) with HF of different etiologies. ALA was assessed by gas chromatography in serum phospholipids, which reflect long-term dietary ALA intake and metabolism.

The primary outcome was a composite of all-cause death or first HF hospitalization. The secondary outcome was the composite of CV death or HF hospitalization.

After a median follow-up of 2.4 years, 140 all-cause deaths, 85 CV deaths, and 141 first HF hospitalizations occurred (composite of all-cause death and first HF hospitalization, 238; composite of CV death and HF hospitalization, 184).

Compared with patients at the lowest quartile of ALA in serum phospholipids, those at the three upper quartiles showed a 39% reduction in the risk of the primary endpoint (hazard ratio, 0.61).

Statistically significant reductions also were observed for all-cause death (HR, 0.58), CV death (HR, 0.51), first HF hospitalization (HR, 0.58), and the composite of CV death and HF hospitalization (HR, 0.58).

By contrast, nonstatistically significant associations were seen for fish-derived EPA, DHA, and the sum of EPA + DHA.

Limitations of the study include its observational nature; a relatively young cohort with reduced or mid-range ejection fraction and stage 2 chronic kidney disease; and no dietary data except for those regarding fatty acids.

“Controversial results from landmark recent trials on omega-3 might have translated into confusion/negative impact on the reputation of these fatty acids,” Dr. Sala-Vila noted. “Many factors affect how each participant responds to a certain intervention (precision nutrition), such as genetics, the microbiome, and the environment. In this regard, nutritional status – omega-3 background – is emerging as a key determinant.”
 

Randomized trials needed

JoAnn E. Manson, MD, MPH, DrPH, chief of the Division of Preventive Medicine at Brigham and Women’s Hospital, Boston, said the findings “are promising in the context of earlier research on omega-3s.”

Those studies include the landmark GISSI-HF trial, a randomized, controlled trial (RCT) that showed a small benefit of n-3 polyunsaturated fatty acids regarding hospital admissions and mortality among patients with chronic HF, and her team’s VITAL-HF study, which showed a significant reduction in recurrent HF hospitalization with marine omega-3 supplementation versus placebo.

“This may not be a causal association, and the authors acknowledge that they don’t have information on other dietary factors,” Dr. Manson said. “It may be that the foods that are leading to this higher blood level of ALA comprise the type of plant-based diet that’s been linked to lower risk of CVD, such as the Mediterranean diet. The findings also could be the result of other factors that aren’t fully controlled for in the analysis, or the participants could be more compliant with their medications.”

Nevertheless, she said, “it’s reasonable to recommend that people with a history of HF or who are at high risk of HF increase their intake of ALA-enriched foods, including canola oil, flaxseed oils, soybeans and soybean oils, and walnuts.”

“I think the evidence is promising enough that an RCT of ALA in people with heart failure also would be reasonable,” she added.

Similarly, Abdallah Al-Mohammad, MD, of Northern General Hospital, Sheffield, England, writes in a related editorial that while a potential role for ALA in improving morbidity and mortality in HF patients cannot be substantiated yet, the findings “open the field to more questions” for which “the judge and jury ... shall be prospective randomized controlled trials.”

No commercial funding or relevant conflicts of interest were declared.

“Controversial results from landmark recent trials on omega-3 might have translated into confusion/negative impact on the reputation of these fatty acids,” Dr. Sala-Vila noted. “Many factors affect how each participant responds to a certain intervention (precision nutrition), such as genetics, the microbiome, and the environment. In this regard, nutritional status – omega-3 background – is emerging as a key determinant.”
 

Randomized trials needed

JoAnn E. Manson, MD, MPH, DrPH, chief of the Division of Preventive Medicine at Brigham and Women’s Hospital, Boston, said the findings “are promising in the context of earlier research on omega-3s.”

Those studies include the landmark GISSI-HF trial, a randomized, controlled trial (RCT) that showed a small benefit of n-3 polyunsaturated fatty acids regarding hospital admissions and mortality among patients with chronic HF, and her team’s VITAL-HF study, which showed a significant reduction in recurrent HF hospitalization with marine omega-3 supplementation versus placebo.

“This may not be a causal association, and the authors acknowledge that they don’t have information on other dietary factors,” Dr. Manson said. “It may be that the foods that are leading to this higher blood level of ALA comprise the type of plant-based diet that’s been linked to lower risk of CVD, such as the Mediterranean diet. The findings also could be the result of other factors that aren’t fully controlled for in the analysis, or the participants could be more compliant with their medications.”

Nevertheless, she said, “it’s reasonable to recommend that people with a history of HF or who are at high risk of HF increase their intake of ALA-enriched foods, including canola oil, flaxseed oils, soybeans and soybean oils, and walnuts.”

“I think the evidence is promising enough that an RCT of ALA in people with heart failure also would be reasonable,” she added.

Similarly, Abdallah Al-Mohammad, MD, of Northern General Hospital, Sheffield, England, writes in a related editorial that while a potential role for ALA in improving morbidity and mortality in HF patients cannot be substantiated yet, the findings “open the field to more questions” for which “the judge and jury ... shall be prospective randomized controlled trials.”

No commercial funding or relevant conflicts of interest were declared.

Heart failure (HF) patients with high serum levels of alpha-linolenic acid (ALA) had a better prognosis than those with the lowest levels, in an observational study.

ALA is an omega-3 fatty acid that is found mainly in plants, including flaxseed, chia, walnuts, or canola oil.

Dr. Sala-Vila and colleagues analyzed data and samples from 905 patients (mean age, 67; 32% women) with HF of different etiologies. ALA was assessed by gas chromatography in serum phospholipids, which reflect long-term dietary ALA intake and metabolism.

The primary outcome was a composite of all-cause death or first HF hospitalization. The secondary outcome was the composite of CV death or HF hospitalization.

After a median follow-up of 2.4 years, 140 all-cause deaths, 85 CV deaths, and 141 first HF hospitalizations occurred (composite of all-cause death and first HF hospitalization, 238; composite of CV death and HF hospitalization, 184).

Compared with patients at the lowest quartile of ALA in serum phospholipids, those at the three upper quartiles showed a 39% reduction in the risk of the primary endpoint (hazard ratio, 0.61).

Statistically significant reductions also were observed for all-cause death (HR, 0.58), CV death (HR, 0.51), first HF hospitalization (HR, 0.58), and the composite of CV death and HF hospitalization (HR, 0.58).

By contrast, nonstatistically significant associations were seen for fish-derived EPA, DHA, and the sum of EPA + DHA.

Four major professional medical societies in the United States have called for urgent action to create a more sustainable model for digestive health care that decreases the environmental impact of gastroenterology practice, according to a new joint strategic plan published simultaneously in Gastroenterology, Gastrointestinal Endoscopy, American Journal of Gastroenterology, and Hepatology.

The plan outlines numerous strategic goals and objectives across clinical care, education, research, and industry to support sustainable practices. With first author Heiko Pohl, MD, a gastroenterologist and hepatologist at the Veterans Affairs Medical Center in White River Junction, Vermont, and professor of medicine at the Geisel School of Medicine at Dartmouth, Hanover, N.H., the joint statement includes task force members from the American Association for the Study of Liver Diseases, American College of Gastroenterology, American Gastroenterological Association, and American Society for Gastrointestinal Endoscopy.

“It is clear that the evolving climate crisis, with its deleterious effects on planetary ecosystems, also poses harm to the health of humankind,” the authors wrote in Gastroenterology.

“Climate change affects many social and environmental determinants of health, including water and food security, shelter, physical activity, and accessible health care,” they added. These changes influence gastrointestinal practice (for example, increased risk of obesity and fatty liver disease, disruption of the microbiome, compromised gut immune function).

At the same time, health care delivery contributes to climate change and greenhouse gas emissions worldwide, they wrote. As a procedure-intensive specialty, digestive health care adds to the health care carbon footprint through single-use supplies and high levels of waste.

“As is the case for the impact of climate change by and on health care systems, there is a vicious cycle whereby climate change negatively impacts individual digestive health, which accelerates specialized health care activity, which further contributes to the climate crisis,” the authors wrote.

The multisociety task force noted the transition to a more sustainable model will be challenging and require major modification of current habits in practice. However, the long-term effects “will promote health, save cost, and ... correspond with a broader shared vision of planetary health,” they wrote.

The strategic plan covers seven domains: clinical settings, education, research, society efforts, intersociety efforts, industry, and advocacy. Each domain has specific initiatives for 2023 to 2027. Years 1 and 2 are conceived as a period of self-assessment and planning, followed by implementation and assessment during years 3-5.

In the plan, clinical settings would assess the carbon footprint and waste within all areas of practice and identify low-carbon and low-waste alternatives, such as immediate, short-term, and long-term solutions. This involves creating a framework for GI practices to develop sustainability metrics and offer affordable testing and treatment alternatives with a favorable environmental impact.

Through education, the societies would raise awareness and share sustainability practices with health care leadership, practitioners, and patients regarding the interactions among climate change, digestive health, and health care services. This would include discussions about the professional and ethical implications of old and new patterns of shared resource utilization.

The societies also support raising and allocating resources for research related to the intersections of climate change, digestive health, and health care, with an emphasis on vulnerable groups. This would encourage the inclusion of environmental considerations in research proposals.

At the GI society level, the groups suggest assessing and monitoring the current environmental impact of society-related activities. This entails identifying and implementing measures that would decrease the carbon footprint and reduce waste, as well as track financial costs and savings and environmental benefits from efforts included in a sustainability model.

At the intersociety level, the U.S. groups would collaborate with national and international GI and hepatology societies to support sustainability efforts and use validated metrics to evaluate their efforts. The multisociety plan has received endorsements from nearly two-dozen groups, including the Crohn’s & Colitis Foundation, World Endoscopy Organization, and World Gastroenterology Organisation.

The plan calls for engagement with GI- and hepatology-focused industry and pharmaceutical partners to develop environmentally friendly products, publish information on carbon footprint implications, and promote options for recycling.

Through advocacy efforts, the societies would also identify and incorporate principles of sustainable health care among the goals of relevant political action committees, as well as leverage collaborative advocacy efforts with national and international health care and research agencies, political leaders, and payors.

“We are grateful that several other GI organizations have endorsed our plan, which reflects the importance and timeliness of the opportunity to work together and share best practices to overcome the burden of climate change on digestive health and help mitigate the environmental impact of GI practice,” the authors concluded.

The authors did not declare a funding source for the report. Several of the authors declared financial relationships with pharmaceutical companies, serving as a consultant or receiving research funding.

Rates of subarachnoid hemorrhage (SAH) are increasing, particularly in Black people, new research suggests.

Results of a new study based on hospital discharge data show Black people have disproportionately high rates of SAH versus other racial groups. Compared with White and Hispanic people, who had an average of 10 cases per 100,000, or Asian people, with 8 per 100,000 people, Black people had an average of 15 cases per 100,000 population.

Whereas case rates held steady for other racial groups in the study over a 10-year period, Black people were the only racial group for whom SAH incidence increased over time, at a rate of 1.8% per year.

“Root causes of the higher SAH incidence in Black [people] are complex and likely extend beyond simple differences in risk factor characteristics to other socioeconomic factors including level of education, poverty level, lack of insurance, access to quality care, and structural racism,” study investigator Fadar Oliver Otite, MD, assistant professor of neurology at SUNY Upstate Medical University, Syracuse, said in an interview.

“Addressing this racial disparity will require multidisciplinary factors targeted not just at subarachnoid hemorrhage risk factors but also at socioeconomic equity,” he added.

The study was published online in Neurology.
 

Uncontrolled hypertension

The average incidence of SAH for all participants was 11 cases per 100,000 people. Men had an average rate of 10 cases and women an average rate of 13 cases per 100,000.

As expected, incidence increased with age: For middle-aged men, the average was four cases per 100,000 people whereas for men 65 and older, the average was 22 cases.

Dr. Otite and his team combined U.S. Census data with two state hospitalization databases in New York and Florida and found that there were nearly 40,000 people hospitalized for SAH between 2007 and 2017. To find annual incidences of SAH per 100,000 population, they calculated the number of SAH cases and the total adult population for the year.

“Smoking and hypertension are two of the strongest risk factors for subarachnoid hemorrhage,” Dr. Otite said. “Hypertension is more prevalent in Black people in the United States, and Black patients with hypertension are more likely to have it uncontrolled.”
 

Racism, toxic stress

Anjail Sharieff, MD, associate professor of neurology at UT Health, Houston, said aside from a high rate of common SAH risk factors such as hypertension, Black Americans also face a barrage of inequities to health education and quality health care that contributes to higher SAH rates.

“The impact of toxic stress related to racism and discrimination experiences, and chronic stress related to poverty, can contribute to hypertension in Black people,” Dr. Sharieff said, adding that these factors contribute to stroke risk and are not usually accounted for in studies.

Dr. Sharieff said many of her first-time patients end up in her office due to a heart attack or stroke because they were previously uninsured and did not have access to primary care. “We need to begin leveraging trust with people in communities – meeting people where they are,” to educate them about hypertension and other health issues, she said.

A shining example of community engagement to reduce hypertension in Black communities was the Cedars-Sinai Barbershop Study, where 52 barbershops in Los Angeles implemented blood pressure checks and interventions among customers. A year later, the project was still working.

“Once we can identify the health problems in Black communities,” said Dr. Sharieff, “we can treat them.”

Dr. Otite and Dr. Sharieff report no relevant financial relationships.
