The scale of mortality from COVID-19 among adults in the United States merits efforts to monitor how many children have lost a parent as a result of the pandemic, wrote Rachel Kidman, PhD, of Stony Brook (N.Y.) University and colleagues.

In a study published in JAMA Pediatrics, the researchers used kinship networks of White and Black individuals in the United States to estimate parental bereavement. They combined deaths from COVID-19 as of February 2021 and combined them with excess deaths, and estimated future bereavement based on a herd immunity scenario.

Overall, the model suggested that each death from COVID-19 results in potential parental bereavement for 0.78 children aged 0-17 years, representing an increase of 17.5%-20.2% in parental bereavement. The model indicated that, as of February 2021, 37,337 children aged 0-17 years had lost a parent to COVID-19, including 11,366 children age 0-9 years and 31,661 children and teens aged 10-17 years. A total of 20,600 of these children were non-Hispanic White and 7,600 were Black. Black children accounted for 20% of the bereaved children, although they account for approximately 14% of children aged 0-17 years in the United States, the researchers noted.

Including the excess death estimate, which refers to the difference between observed and expected deaths for the remainder of the pandemic, raised the total bereaved children to 43,000. A future mortality scenario using a total of 1,500,000 deaths from COVID-19 based on a natural herd immunity strategy increased the total estimate of bereaved children to 116,922.

The study findings were limited by several factors including the lack of data on nonparental primary caregivers, and the use of demographic models rather than survey or administrative data, the researchers noted.

However, the huge number of children who have experienced the death of a parent because of COVID-19 emphasizes the need for reforms to address health, educational, and economic impacts of this mass bereavement on children and teens, they said.

“Parentally bereaved children will also need targeted support to help with grief, particularly during this period of heightened social isolation,” they emphasized.

Establishment of a national child bereavement cohort could identify children early in the bereavement process to help ensure that they are connected to local supportive care and monitored for health and behavior problems, the researchers said. In addition, such a cohort could be used as a basis for a longitudinal study of the impact of mass parental bereavement during a unique period of social isolation and economic uncertainty, they concluded.
 

Study spotlights gaps in mental health care

The study is an important reminder of how COVID-19 has disrupted children’s lives, said Herschel Lessin, MD, of Children’s Medical Group in Poughkeepsie, N.Y., in an interview. Losing a parent because of COVID-19 is one more tragedy on the list of social and emotional disasters the pandemic has wrought on children, he said.

“There has to be some sort of national response to help children through all of this, not just one item at a time,” Dr. Lessin said. However, the management of children’s mental health in the United States has been subpar for decades, he noted, with few clinicians trained to specialize in treating behavioral and mental health issues in children. Consequently, more general pediatricians will continue to be faced with the mental health issues of bereaved children who desperately need support, he said.

Money remains a key barrier, as it keeps qualified clinicians from entering the field of pediatric mental and behavioral health, and even where there are mental health providers, most do not take insurance and have long waiting lists, Dr. Lessin noted.

General pediatricians were seeing more patients with ADHD, anxiety, and depression before the advent of COVID-19, though most are not trained in managing these conditions, said Dr. Lessin. “Approximately 25%-30% of my visits now are mental health related, and the pandemic will make it geometrically worse,” he said.

The current study, with its dramatic estimates of the number of children who have lost a parent because of COVID-19, may bring attention to the fact that more training and money are needed to support mental health programs for children, he said.

Lead author Dr. Kidman had no financial conflicts to disclose. The study was supported by grants to corresponding author Ashton M. Verdery, PhD, from the National Institute on Aging and the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Dr. Lessin had no financial conflicts but serves on the Pediatric News editorial advisory board.

Patients with COPD may benefit from stepped-up treatment of short-term disease progression with triple therapy to stave off longer-term exacerbations and all-cause mortality.

Clinically important deterioration was a significant predictor of worsening disease and all-cause mortality in chronic obstructive pulmonary disease, a study based on data from more than 10,000 patients has shown.

For this study, clinically important deterioration (CID) as a measure of COPD is defined as a combination of change in lung function and/or health status, or a first acute moderate to severe COPD exacerbation, wrote MeiLan K. Han, MD, of the University of Michigan, Ann Arbor, and colleagues.

The study was published in ERJ Open Research The investigators analyzed data from the IMPACT trial, a phase III, double-blind, multicenter, 52-week study of symptomatic COPD patients aged 40 years and older.

In the intent-to-treat population, patients with symptomatic COPD and at least one moderate or severe exacerbation in the past year were randomized to a once-daily dose of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 mcg (4,151 patients); FF/VI 100/25 mcg (4,134 patients); or UMEC/VI 62.5/25 mcg using a single dry-power inhaler (2,070 patients).

The researchers explored both the prognostic value of a CID event on future clinical outcomes and the impact of single-inhaler triple versus dual therapy on reducing CID risk. CID was defined as any of the following: moderate/severe exacerbation; deterioration in lung function (defined as a decrease of 100 mL or more from baseline in trough forced expiratory volume per second); or deterioration in health status based on increases of 4.0 units or more on the St George’s Respiratory Questionnaire (SGRQ) total score or 2.0 units or more on the COPD Assessment Test (CAT) score.

Overall, patients with a CID by 28 weeks had significantly increased exacerbation rates after week 28, as well as smaller improvements in lung function and health status at week 52 (P < .001 for all). In addition, CID patients had an increased risk of all-cause mortality after 28 weeks, compared with patients without CID. However, FF/UMEC/VI significantly reduced CID risk, compared with dual therapies, the researchers noted.

Based on the CID SGRQ definition, patients with CID had a 75% increase in moderate to severe exacerbations by week 28 and a 96% in severe exacerbations over weeks 29-52. The increases were similar using the CID CAT definition (72% and 91%, respectively).

Patients with CID also showed significantly reduced improvements in both lung function and health status after 1 year, and a significantly increased risk of all-cause mortality compared to patients without CID.

In comparing triple vs. double therapies, FF/UMEC/VI patients showed significant reductions in CID risk by 52 weeks, compared with patients treated with FF/VI and UMEC/VI. This difference was true across all subgroups, except for the subgroup of patients who were on long-acting beta2-agonist (LABA) and long-acting muscarinic antagonist (LAMA) therapy prior to screening, the researchers said.

In addition, “treatment effect was greater at higher blood eosinophil counts for FF/UMEC/VI versus UMEC/VI,” the researchers noted.

The study findings were limited by several factors including the lack of CID as a primary endpoint, the relatively short 5-month follow-up period, and the use of a symptomatic patient population with an established risk of exacerbation, which could limit generalizability, the researchers noted. However, the findings support the value of preventing short-term CID and adding inhaled corticosteroids (ICS) or bronchodilation for patients in this study population, they said.
 

Data may help drive tailored treatments

“This study is a post hoc analysis of data from the IMPACT trial, an RCT examining triple therapy vs ICS/LABA vs LABA/LAMA,” Dr. Han, lead and corresponding author, said in an interview. “In this particular paper, we conducted a treatment independent analysis examining individuals who experienced clinically important deteriorations at week 28 and then compared outcomes at week 52 based on CID status at week 28. Patients with a CID by week 28 had significantly increased exacerbation rates after week 28, smaller improvements in lung function and health status at week 52, and increased risk of all-cause mortality after week 28 versus patients who were CID free,” she emphasized. “We also saw that FF/UMEC/VI significantly reduced CID risk versus dual therapies.” These data suggest that shorter-term changes are associated with longer term outcomes, and provide important information both for the purposes of clinical trials design as well as patient clinical assessments, she added.

Dr. Han said she was not surprised by the findings. “I think these results are consistent with prior analyses but suggest that short-term outcomes relate to longer-term ones,” she said. However, she stressed the need for individualized treatment.

“While there are relationships between symptoms, lung function, and exacerbations as demonstrated by these analyses, in any individual patient sometimes these three disease axes do not perfectly align,” she explained. Dr. Han’s main message for clinicians in practice is that optimization of triple therapy in patients with severe disease and high risk for exacerbations was associated not only with short-term improvements in symptoms and lung function, but also with longer-term reductions in exacerbations and mortality.

As for additional research, prospective studies using CID as a primary or secondary outcome would help validate the composite outcome in this study, as regulatory agencies have been slow to adopt composite outcomes, Dr. Han said.

Dr. Han disclosed relationships with GlaxoSmithKline, which funded the study, as well as AstraZeneca, Boehringer Ingelheim, Novartis, Sunovion, Mylan, Merck, and Verona.

Dr. Hammond served on the Ob.Gyn. News Advisory Board for 33 years. His service as a board member was one of many leadership roles to which he dedicated his time and expertise. Dr. Hammond served as president of the American College of Obstetrics & Gynecology (ACOG) from 2002 to 2003, and received a Lifetime Achievement Award from ACOG in 2015. He also served as president of the American Society of Reproductive Medicine, president of the American Gynecological and Obstetrical Society, and president of the North Carolina Obstetrical and Gynecological Society.

Dr. Hammond was honored by Duke University, Durham, N.C., as E.C. Hamblen Professor Emeritus in 2010, after more than 40 years in academia. He held the title of Edwin Crowell Hamblen Distinguished Professor of Reproductive Biology and Family Planning and Chair of the Department of Obstetrics & Gynecology from 1980 to 2002. During this time, he distinguished himself for his work in pioneering treatments for gestational trophoblastic disease. As an extension of this research, he was a founder of the Southeast Regional Trophoblastic Disease Center. In addition, Dr. Hammond was often consulted for his expertise on issues related to menopause and hormone replacement therapy.

Dr. Hammond began his medical career at Duke University after graduating from The Citadel with a bachelor of science degree in 1958. After earning his medical degree in 1961, he remained at Duke as a resident in obstetrics and gynecology, followed by completion of a fellowship in reproductive endocrinology in 1964. From 1964 to 1966, he served at the National Institutes of Health as a fellow in the National Cancer Institute and the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

A few years later, in 1969, Dr. Hammond launched his long and distinguished academic career with an assistant professor position in the department of obstetrics & gynecology at Duke.

Dr. Hammond’s many honors include a National Association for Women’s Health Lifetime Achievement Award and membership in the Institute of Medicine, now the National Academy of Medicine. He also was named a fellow of the Royal College of Obstetricians and Gynaecologists, and an honorary member of the Canadian Society of Obstetrics and Gynecology. Dr. Hammond will be remembered not only as a physician, researcher, educator, and mentor, but also an advocate for women’s health.

More adolescent girls than boys experienced nonfatal opioid overdose and reported baseline levels of anxiety, depression, and self-harm, according to data from a retrospective cohort study of more than 20,000 youth in the United States.

Previous studies have identified sex-based differences in opioid overdose such as a higher prevalence of co-occurring psychiatric disorders in women compared with men, wrote Sarah M. Bagley, MD, of Boston University, and colleagues. “However, few studies have examined whether such sex-based differences in opioid overdose risk extend to the population of adolescents and young adults,” they said.

In a retrospective cohort study published in JAMA Network Open, the researchers identified 20,312 commercially insured youth aged 11-24 years who experienced a nonfatal opioid overdose between Jan. 1, 2006, and Dec. 31, 2017, and reviewed data using the IBM MarketScan Commercial Database. The average age of the study population was 20 years and approximately 42% were female.

Females aged 11-16 years had a significantly higher incidence of nonfatal opioid overdose (60%) compared with males, but this trend reversed at age 17 years, after which the incidence of nonfatal opioid overdose became significantly higher in males. “Our finding that females younger than 17 years had a higher incidence of NFOD is consistent with epidemiologic data that have indicated changes in alcohol and drug prevalence among female youths,” the researchers wrote.

Overall, 57.8% of the cohort had mood and anxiety disorders, 12.8% had trauma- or stress-related disorders, and 11.7% had attention-deficit/hyperactivity disorder.

When analyzed by sex, females had a significantly higher prevalence than that of males of mood or anxiety disorders (65.5% vs. 51.9%) trauma or stress-related disorders (16.4% vs. 10.1%) and attempts at suicide or self-harm (14.6% vs. 9.9%). Males had significantly higher prevalence than that of females of opioid use disorder (44.7% vs. 29.2%), cannabis use disorder (18.3% vs. 11.3%), and alcohol use disorder (20.3% vs. 14.4%).

“Although in our study, female youths had a lower prevalence of all substance use disorders, including OUD [opioid use disorder], and a higher prevalence of mood and trauma-associated disorders, both male and female youths had a higher prevalence of psychiatric illness and substance use disorder than youths in the general population,” the researchers noted.

The study findings were limited by several factors including the inclusion only of youth with commercial insurance, with no uninsured or publicly insured youth, and only those youth who sought health care after a nonfatal opioid overdose, the researchers noted. The prevalence of substance use and mental health disorders may be over- or underdiagnosed, and race was not included as a variable because of unreliable data, they added. The database also did not allow for gender identity beyond sex as listed by the insurance carrier, they said.

However, the results indicate significant differences in the incidence of nonfatal opioid overdose and accompanying mental health and substance use disorders based on age and sex, they said.

“These differences may have important implications for developing effective interventions to prevent first-time NFOD and to engage youths in care after an NFOD,” they concluded.

The study was supported by grants to several researchers from the National Institute on Drug Abuse, National Institutes of Health, and the Charles A. King Trust. The researchers had no financial conflicts to disclose.

Physicians are active on social media with contact dermatitis content, but they can take more advantage of this opportunity to educate patients, according to a review of posts on YouTube, Facebook, Instagram, Google, Twitter, and Reddit.

Data on social media use suggest that approximately 65% of U.S. adults regularly use social media, and 40% of individuals use it in making medical decisions, Morgan Nguyen, a medical student at Northwestern University, Chicago, said at the annual meeting of the American Contact Dermatitis Society, held virtually this year.

“Dermatologists’ awareness of social media discussions can further their understanding of where patients go for information and what they might encounter,” she said. In particular, “contact dermatitis practitioners can tailor their counseling by knowing what their patients are seeing online.”

To characterize the social media landscape for content related to allergic contact dermatitis (ACD), Ms. Nguyen and colleagues assessed metrics on content and authorship on six different platforms.

For YouTube, the authors reviewed 15 videos related to ACD with views ranging from 24,262 to 232,300. Of these videos, two were produced as medical education, four were produced by patients, and nine were produced by physicians. The content of many videos was poor quality, with an average QUEST score of 7.4/28 overall and 8.7 for physician videos. Video quality was not associated with increased views. Video titles included “What to do if you have a rash on your face,” and “Contact dermatitis on lips!”

Overall, Instagram was more popular than Twitter, particularly among patients. The investigators searched using the hashtags #ContactDermatitis, #AllergicContactDermatitis, and #ContactDerm and reviewed the 100 most recent posts for authorship. The most recent 100 posts occurred over 16 days; physicians, patients, and companies each contributed approximately one-third of the content, but patient content was more focused on symptoms, treatment progress, and advice.

For Instagram, the hashtag search phrase made a notable difference in authorship, Ms. Nguyen said. Physicians were disproportionately more likely to use #AllergicContactDermatitis (43%) compared with patients (22%).

On Twitter, the most recent 100 posts were spread over 152 days, and professional organizations and companies generated approximately two-thirds of the posts. The #ContactDermatitis hashtag was the most common, and accounted for 94% of tweets.

Although patient support groups specific to ACD exist on Facebook, the researchers found none on Reddit. These two venues are designed for creating online communities, rather than simply providing information, and the researchers searched for support groups related to contact dermatitis. One of the main differences between the two is that Facebook allows for the creation of private groups, while Reddit is an open forum.

The largest contact dermatitis Facebook group, the “Eczema, Contact Dermatitis and Patch Testing Alliance,” had 4,665 members at the time of the study, and most groups were private. Although no support groups existed on Reddit, titles of Reddit forums discussing ACD included allergies, askdoctors, fragrance, haircarescience, legaladvice, skincareaddicts, beauty, dermatologyquestions, medical_advice, skincare_addiction, tretinoin, and vulvodynia.

For Google, the researchers used terms similar to “contact dermatitis” as generated by the Google Keyword Planner tool, and used Google Adwords data to estimate monthly searches. The top estimated term was “contact dermatitis,” with 8,322 searches, followed by “contact dermatitis pictures,” with 1,666 searches, and “contact dermatitis treatment” with 595 searches. By contrast, “allergic dermatitis” had an estimated 346 monthly searches, and “allergic contact dermatitis” had 194.

Overall, approximately 9,000 searches each month involve “contact dermatitis,” “allergic contact dermatitis,” or “allergic dermatitis,” said Ms. Nguyen. However, these estimated searches seemed comparatively low, given the high burden of ACD, she said. Although ACD ranks eighth among skin diseases based on health care costs, psoriasis (fourteenth based on health care costs) shows an estimated monthly Google search volume of 600,462, she pointed out.

The study findings were limited by several factors including the potential impact of the COVID-19 pandemic on social media use, and by the lack of specificity associated with the search term “contact dermatitis,” which is not unique to ACD, Ms. Nguyen said.

Although more research on quality assessment is needed, the results suggest that social media is a popular venue for ACD patients to seek and share information, Ms. Nguyen emphasized. There is an opportunity for patch testing physicians to create and disperse educational content for patients using these sites, she concluded.
 

Study highlights education opportunities

“Due to the pandemic, patients have been increasingly interacting with online resources in lieu of coming to a physician’s office,” corresponding author Walter J. Liszewski, MD, of the department of dermatology, Northwestern University, Chicago, said in an interview. “As social media is increasingly used by patients and physicians, it is important to get a sense of its footprint,” he said.

He and Ms. Nguyen were surprised by several of their findings: First, searches for ACD on Google were not particularly common given its relatively high prevalence and economic cost to society. In addition, they found that physicians often used different language than that of patients to describe ACD on Twitter and Instagram. They were also surprised at how often ACD appeared in Reddit posts, which they noted highlights that ACD impacts multiple sections of society.

The greatest challenge in studying social media and medicine is the quality of material available, Dr. Liszewski and Ms. Nguyen observed, emphasizing that while there are numerous videos on ACD on YouTube, the quality is highly variable, and there is a need for more patient-centered, educational materials. However, the results of their study highlight the opportunity for physicians and industry to create medically-accurate educational materials, they added.

Approximately 20% of shoe allergens are not detected with the current screening series, according to a retrospective study of more than 30,000 patients.

Contact allergy to shoes remains a common but difficult problem for many reasons, including the limited information from shoe manufacturers, differences in shoe manufacturing processes, and changes in shoe trends, said Raina Bembry, MD, a dermatitis research fellow at Duke University, Durham, N.C., in a presentation at the annual meeting of the American Contact Dermatitis Society.

The North American Contact Dermatitis Group (NACDG) published data on shoe allergens from 2001-2004 in a 2007 review. To update this information to reflect changes in shoe manufacturing and trends, she and her coinvestigators characterized demographics, clinical characteristics, patch test results, and occupational data for NACDG patients with shoe contact allergy. They identified 33,661 patients who were patch tested with the standard series with or without a supplemental allergen between 2005 and 2018; over half were over aged 40.

The primary focus was individuals with a confirmed shoe (defined as shoes, boots, sandals, or slippers) as the source of a screening allergen or supplemental allergen, a positive patch test, and the foot as one of three sites of involvement. A total of 352 individuals met these criteria and had a confirmed final diagnosis of allergic contact dermatitis, Dr. Bembry said. Compared with individuals who had positive patch tests without a confirmed diagnosis, those with confirmed allergic dermatitis were significantly more likely to be male (odds ratio, 3.36) and less likely to be over aged 40 years (OR, 0.49).

The most common NACDG screening allergen, potassium dichromate, was found in 29.8% of the study population, followed by p-tert-butylphenol formaldehyde resin in 20.1%, thiuram mix (13.3%), mixed dialkyl thioureas (12.6%) and carba mix (12%).

Notably, 29.8% of the patients showed positive patch test reactions to supplemental allergens, and 12.2% only reacted to supplemental allergens, Dr. Bembry said.

The results were limited by several factors, including referral selection bias, reliance on clinical judgment for patch test interpretations, and lack of data on the specifics of the supplemental allergens other than the source code, she said. In addition, the study does not identify nonshoe sources of foot contact allergy, and six screening allergens were not testing during this study period.

Overall, the findings were similar to those from previous studies in that patients affected with contact dermatitis from shoe allergens tended to be younger and male, with no occupational relevance to the reaction, said Dr. Bembry.

The finding that almost 20% of allergens were not found with the screening series emphasizes the value of testing not only relevant supplemental allergens, but also patient products and shoe components, she concluded.

Dr. Bembry had no financial conflicts to disclose. Coauthor Amber Atwater, MD, the immediate past president of the ACDS, and associate professor of dermatology at Duke University, disclosed receiving the Pfizer Independent Grant for Learning & Change and consulting for Henkel.

Approximately 20% of shoe allergens are not detected with the current screening series, according to a retrospective study of more than 30,000 patients.

Contact allergy to shoes remains a common but difficult problem for many reasons, including the limited information from shoe manufacturers, differences in shoe manufacturing processes, and changes in shoe trends, said Raina Bembry, MD, a dermatitis research fellow at Duke University, Durham, N.C., in a presentation at the annual meeting of the American Contact Dermatitis Society.

The North American Contact Dermatitis Group (NACDG) published data on shoe allergens from 2001-2004 in a 2007 review. To update this information to reflect changes in shoe manufacturing and trends, she and her coinvestigators characterized demographics, clinical characteristics, patch test results, and occupational data for NACDG patients with shoe contact allergy. They identified 33,661 patients who were patch tested with the standard series with or without a supplemental allergen between 2005 and 2018; over half were over aged 40.

The primary focus was individuals with a confirmed shoe (defined as shoes, boots, sandals, or slippers) as the source of a screening allergen or supplemental allergen, a positive patch test, and the foot as one of three sites of involvement. A total of 352 individuals met these criteria and had a confirmed final diagnosis of allergic contact dermatitis, Dr. Bembry said. Compared with individuals who had positive patch tests without a confirmed diagnosis, those with confirmed allergic dermatitis were significantly more likely to be male (odds ratio, 3.36) and less likely to be over aged 40 years (OR, 0.49).

The most common NACDG screening allergen, potassium dichromate, was found in 29.8% of the study population, followed by p-tert-butylphenol formaldehyde resin in 20.1%, thiuram mix (13.3%), mixed dialkyl thioureas (12.6%) and carba mix (12%).

Notably, 29.8% of the patients showed positive patch test reactions to supplemental allergens, and 12.2% only reacted to supplemental allergens, Dr. Bembry said.

The results were limited by several factors, including referral selection bias, reliance on clinical judgment for patch test interpretations, and lack of data on the specifics of the supplemental allergens other than the source code, she said. In addition, the study does not identify nonshoe sources of foot contact allergy, and six screening allergens were not testing during this study period.

Febuxostat (Uloric) was not associated with increased cardiovascular risk in patients with gout when compared to those who used allopurinol, in an analysis of new users of the drugs in Medicare fee-for-service claims data from the period of 2008-2016.

The findings, published March 25 in the Journal of the American Heart Association, update and echo the results from a similar previous study by the same Brigham and Women’s Hospital research group that covered 2008-2013 Medicare claims data. That original claims data study from 2018 sought to confirm the findings of the postmarketing surveillance CARES (Cardiovascular Safety of Febuxostat and Allopurinol in Patients With Gout and Cardiovascular Morbidities) trial that led to a boxed warning for increased risk of cardiovascular and all-cause mortality vs. allopurinol. The trial, however, did not show a higher rate of major adverse cardiovascular events (MACE) overall with febuxostat.

The recency of the new data with more febuxostat-exposed patients overall provides greater reassurance on the safety of the drug, corresponding author Seoyoung C. Kim, MD, of Brigham and Women’s Hospital and Harvard Medical School, Boston, said in an interview. “We also were able to get data on cause of death, which we did not have before when we conducted our first paper.”

Dr. Kim said she was not surprised by any of the findings, which were consistent with the results of her earlier work. “Our result on CV death also was consistent and reassuring,” she noted.

The newest Medicare claims study also corroborates results from FAST (Febuxostat Versus Allopurinol Streamlined Trial), a separate postmarketing surveillance study that was ordered by the European Medicines Agency after febuxostat’s approval in 2009. It showed that the two drugs were noninferior to each other for the risk of all-cause mortality or a composite cardiovascular outcome (hospitalization for nonfatal myocardial infarction, biomarker-positive acute coronary syndrome, nonfatal stroke, or cardiovascular death).

“While CARES showed higher CV death and all-cause death rates in febuxostat compared to allopurinol, FAST did not,” Dr. Kim noted. “Our study of more than 111,000 older gout patients treated with either febuxostat or allopurinol in real-world settings also did not find a difference in the risk of MACE, CV mortality, or all-cause mortality,” she added. “Taking these data all together, I think we can be more certain about the CV safety of febuxostat when its use is clinically indicated or needed,” she said.

Study details

Dr. Kim, first author Ajinkya Pawar, PhD, of Brigham and Women’s, and colleagues identified 467,461 people with gout aged 65 years and older who had been enrolled in Medicare for at least a year. They then used propensity-score matching to compare 27,881 first-time users of febuxostat with 83,643 first-time users of allopurinol on the primary outcome of the incidence of major adverse cardiovascular events (MACE), defined as the first occurrence of myocardial infarction, stroke, or cardiovascular mortality.

In the updated study, the mean follow‐up periods for febuxostat and allopurinol were 284 days and 339 days, respectively. Overall, febuxostat was noninferior to allopurinol with regard to MACE (hazard ratio, 0.99; 95% confidence interval, 0.93-1.05), and the results were consistent among patients with baseline CVD (HR, 0.94). In addition, rates of secondary outcomes of MI, stroke, and cardiovascular mortality were not significantly different between febuxostat and allopurinol patients, except for all-cause mortality (HR, 0.92; 95% CI, 0.87-0.98).

The study findings were limited mainly by the potential bias caused by nonadherence to medications, and potential for residual confounding and misclassification bias, the researchers noted.

However, the study was strengthened by its incident new-user design that allowed only patients with no use of either medication for a year before the first dispensing and its active comparator design, and the data are generalizable to the greater population of older gout patients, they said.

Consequently, the data from this large, real-world study support the safety of febuxostat with regard to cardiovascular risk in gout patients, including those with baseline cardiovascular disease, they concluded.

The study was supported by the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital. Dr. Kim disclosed research grants to Brigham and Women’s Hospital from Roche, Pfizer, AbbVie, and Bristol‐Myers Squibb for unrelated studies. Another author reported serving as the principal investigator with research grants from Vertex, Bayer, and Novartis to Brigham and Women’s Hospital for unrelated projects.

Two reports support the safety and immunogenicity of SARS-CoV-2 mRNA vaccines in patients with rheumatic and musculoskeletal diseases (RMDs) and represent the first available data on such patients.

In an observational cohort study published in Annals of the Rheumatic Diseases, Caoilfhionn M. Connolly, MD, of Johns Hopkins University, Baltimore, and colleagues reviewed data from 325 adults with RMDs who received the first dose of SARS-CoV-2 mRNA vaccine during the period of Dec. 17, 2020, to Feb. 11, 2021. Of these, 51% received the Pfizer/BioNTech vaccine and 49% received the Moderna vaccine.

The patients, who were invited to participate on social media, were aged 34-54 years, 96% were women, and 89% were White. Inflammatory arthritis was the most common RMD condition (38%), followed by systemic lupus erythematosus (28%) and overlap connective tissue disease (19%). The patients were using a range of immunomodulatory treatment regimens, including nonbiologic disease modifying antirheumatic drugs (DMARDs) in 44%, biologics in 19%, and combination therapy in 37%.

Overall, 89% of patients reported localized symptoms of pain, swelling, and erythema, and 69% reported systemic symptoms. Fatigue was the most common systemic symptom, and 7.4% reported severe fatigue.

None of the patients experienced allergic reactions requiring epinephrine, and 3% reported new infections that required treatment.

“These early, reassuring results may ameliorate concern among patients and provide guidance for rheumatology providers in critical discussions regarding vaccine hesitancy or refusal,” they concluded.

Antibody responses

In another study published in Annals of the Rheumatic Diseases by the same group of researchers, antibody responses against the receptor binding domain of the SARS-CoV-2 spike protein were seen in 74% of 123 adults with an RMD at 18-26 days after receiving a first dose of SARS-CoV-2 mRNA vaccine (52% Pfizer vaccine and 48% Moderna) between Jan. 8, 2021, and Feb. 12, 2021.

The most common diagnoses in these patients were inflammatory arthritis (28%), systemic lupus erythematosus (20%), and Sjögren’s syndrome (13%). A total of 28% of participants reported taking no immunomodulatory agents, 19% reported nonbiologic DMARDs, 14% reported biologic DMARDs, and 19% reported combination therapy.

Although no differences appeared based on disease groups or overall categories of immunomodulatory therapies, patients whose treatment included mycophenolate or rituximab were significantly less likely to develop antibody responses than were patients not taking these medications (P = .001 and P = .04, respectively). Although rituximab and methotrexate have been associated with reduced responses to vaccines such as the flu vaccine, methotrexate was not associated with reduced vaccine response in this study. A total of 94% of patients taking a tumor necrosis factor inhibitor had detectable antibodies.

The studies’ findings were limited by several factors including a lack of longer-term safety data; the small, nonrandomized sample of mainly white women; limited information on immunomodulatory drug dosage and timing; lack of serial antibody measurements; use of an enzyme immunoassay designed to detect antibody response after natural infection; and the inclusion of data only on the first dose of a two-dose vaccine series, the researchers noted. However, the data should provide additional reassurance to RMD patients and their health care teams about vaccination against COVID-19, they said.

Both studies were supported by the Ben-Dov family. In addition, the studies were supported by grants to various study authors from the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute of Allergy and Infectious Diseases, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, and the Transplantation and Immunology Research Network of the American Society of Transplantation. One author disclosed financial relationships with Sanofi, Novartis, CSL Behring, Jazz Pharmaceuticals, Veloxis, Mallinckrodt, and Thermo Fisher Scientific. The other researchers had no financial conflicts to disclose.

The American Contact Dermatitis Society has selected acetophenone azine, linked to reactions associated with shins pads and footwear, as the “Contact Allergen of the Year” for 2021.

The announcement was made by Donald V. Belsito, MD, professor of dermatology, Columbia University, New York, during a presentation at the annual meeting of the American Contact Dermatitis Society, held virtually this year. In his opinion, he said, the most exciting selections occur when international cooperation results in the identification of a new allergen that could become problematic, and acetophenone azine falls into this category.

The chemical formula of acetophenone azine is C₁₆H₁₆N₂.

Acetophenone azine was highlighted as a contact allergen in a recent report in Dermatitis. The authors, Nadia Raison-Peyron, MD, from the department of dermatology at the University of Montpelier (France), and Denis Sasseville, MD, from the division of dermatology at McGill University Health Center, Quebec, described publications and reports of about 12 cases of severe allergic contact dermatitis secondary to shin pads or footwear, mainly in children and teens in Europe (one case was in Canada).

A common feature of these cases was the presence of a foam used for cushioning, made of ethyl vinyl acetate (EVA) used in the relevant products.

In one case, a 13-year-old boy who wore shin pads for soccer developed contact dermatitis on both shins that spread, and was described as severe. Patch testing revealed the EVA foam in the shin pads as the only positive reaction. Similar cases have been reported after exposure to EVA-containing products, including shin pads, sneakers, flip-flops, ski boots, insoles, swimming goggles, and bicycle seats, according to the authors.

In some reports, cases related to footwear presented as dyshidrosiform, vesiculobullous eczema, with or without palmar lesions, or presented as plantar hyperkeratotic dermatitis, they wrote. In other cases, patients experienced scarring and postinflammatory hypopigmentation.

The compound is likely not added to EVA intentionally, they added, but instead is thought to result from reactions between additives during the manufacturing process. The presence of acetophenone azine is not well explained, but the current theory is that it results from a combination of “the degradation of the initiator dicumylperoxide and hydrazine from the foaming agent azodicarbonamide,” the authors said.

In the paper, Dr. Raison-Peyron and Dr. Sasseville recommended a patch testing concentration of 0.1% in acetone or petrolatum, as acetophenone azine is not currently available from path test suppliers, although it can be obtained from chemical product distributors.

“Given the recent discovery of this allergen, it is presumed that cases of allergic contact dermatitis would have been missed and labeled irritant contact dermatitis or dyshidrosis,” they noted. To avoid missing more cases, acetophenone azine should be added to the patch testing shoe series, as well as plastics and glues series, they emphasized.

Although no cases of allergic reactions to acetophenone azine have been reported in the United States to date, it is an emerging allergen that should be on the radar for U.S. dermatologists, Amber Atwater, MD, outgoing ACDS president, said in an interview. The lack of reported cases may be in part attributed to the fact that acetophenone azine is not yet available to purchase for testing in the United States, and the allergen could be present in shin guards and other products identified in reported cases, added Dr. Atwater, associate professor of dermatology, Duke University, Durham, N.C.

The announcement was made by Donald V. Belsito, MD, professor of dermatology, Columbia University, New York, during a presentation at the annual meeting of the American Contact Dermatitis Society, held virtually this year. In his opinion, he said, the most exciting selections occur when international cooperation results in the identification of a new allergen that could become problematic, and acetophenone azine falls into this category.

The chemical formula of acetophenone azine is C₁₆H₁₆N₂.

Acetophenone azine was highlighted as a contact allergen in a recent report in Dermatitis. The authors, Nadia Raison-Peyron, MD, from the department of dermatology at the University of Montpelier (France), and Denis Sasseville, MD, from the division of dermatology at McGill University Health Center, Quebec, described publications and reports of about 12 cases of severe allergic contact dermatitis secondary to shin pads or footwear, mainly in children and teens in Europe (one case was in Canada).

A common feature of these cases was the presence of a foam used for cushioning, made of ethyl vinyl acetate (EVA) used in the relevant products.

Patients treated with infliximab for inflammatory bowel disease (IBD) showed significantly reduced response to COVID-19 antibodies, compared with those treated with vedolizumab, according to data from nearly 7,000 patients.

Although anti–tumor necrosis factor (anti-TNF) drugs are routinely used for patients with IBD, the impact of their immune-suppressing properties on protective immunity to COVID-19 is unknown, wrote Nicholas A. Kennedy, MD, of the University of Exeter (England) and colleagues. These drugs have been reported to impair protective immunity following vaccines for other diseases, such as those for influenza and viral hepatitis.

“By suppressing immune responses, biological and immunosuppression therapies may lead to chronic SARS-CoV-2 infection and have recently been implicated in the evolution and emergence of novel variants,” they noted, citing a study published in Cell.

In the current study, published in Gut, the researchers used data from the CLARITY IBD study to identify 6,935 patients with IBD aged 5 years and older seen at 92 hospitals in the United Kingdom between Sept. 22, 2020, and Dec. 23, 2020. Of these, 4,685 were treated with infliximab, and 2,250 received vedolizumab. The proportion of study participants with a positive anti–SARS-CoV-2 antibody test was the primary outcome, with secondary outcomes including proportion with positive antibodies following positive polymerase chain reaction test for SARS-CoV-2 and the magnitude of antibody reactivity.

Substantial seroprevalence differences seen

Overall, rates of symptomatic and proven SARS-CoV-2 infection and hospitalization were similar between infliximab-treated and vedolizumab-treated patients with IBD. However, seroprevalence was significantly lower in the infliximab group, compared with the vedolizumab group (3.4% vs. 6.0%; P < .0001). In addition, infliximab and immunomodulator use were each independently associated with lower seropositivity, compared with vedolizumab (odds ratio, 0.66 for infliximab and OR, 0.70 for immunomodulators) in a multivariate analysis.

In a sensitivity analysis, 39 of 81 infliximab-treated patients with polymerase chain reaction–confirmed COVID-19 infection seroconverted (48%), compared with 30 of 36 vedolizumab-treated patients (83%) (P < .00044). Infliximab-treated patients with confirmed infections also showed a lower magnitude of anti–SARS-CoV-2 reactivity, compared with vedolizumab-treated patients (P < .0001).

From a clinical perspective, the lower seroconversion rates and reduced levels of anti–SARS-CoV-2 antibody reactivity might increase susceptibility to recurrent COVID-19 infections in infliximab-treated IBD patients, the researchers noted. In addition, the impaired serological responses might promote chronic nasopharyngeal colonization and consequently promote the development of COVID-19 variants and drive persistent transmission, the researchers said.

The study findings were limited by several factors including lack of knowledge on the impact of attenuated immune response on infection risk, the potential for recall bias associated with patient reports, and the focus on infliximab only, the researchers pointed out. However, the key findings are likely apply to other anti-TNF monoclonal antibodies including adalimumab, certolizumab and golimumab, they suggested.

The study was strengthened by the recruitment of a large number of patients in a narrow time frame and comprehensive collection of data on patient-reported outcomes, COVID-19 testing, and serological assay results, the researchers said. Overall, the findings support the public health value of serological testing and virus surveillance to identify suboptimal vaccine response and to consider implications for practice, they added. “If attenuated serological responses following vaccination are also observed, then modified immunization strategies will need to be designed for millions of patients worldwide,” they emphasized.

Findings inform clinical practice and public health

The study is very important for many reasons, said Kim L. Isaacs, MD, PhD, AGAF, of the University of North Carolina at Chapel Hill in an interview. “It is known that there is decreased responsiveness to a number of routine vaccinations in IBD patients on immune active therapy. In terms of SARS-CoV-2, development of an immune response with infection is important in terms of severity of infection, reinfection, and possibly limiting spread of infection in this patient population,” she said. “Looking at both serum seroconversion and reactivity of immune response in patients with known SARS-CoV-2 infection will help to define clinical and public health guidance, and also may be predictive as to what might happen with SARS-CoV-2 immunization based on background biologic or immunosuppressant therapy,” she noted.

Dr. Isaacs said that she was not surprised by the study findings. “Anti-TNF, thiopurine, and methotrexate therapy are all thought to be systemically active and likely to suppress the immune response to infection and vaccination,” she said. Vedolizumab, on the other hand, is thought to be less systemically active and clinically is associated with fewer serious infections.

Data will drive patient counseling 

“These results affect counseling of IBD patients on immune active therapy who have had a SARS-CoV-2 infection,” said Dr. Isaacs. “They should be made aware that infection does not indicate protection for further infection. Although the issues that are raised in this study are of concern, patients should not have clinically beneficial therapy discontinued or switched based on these results,” she said.

“Additional research is needed to determine what the seroconversion rate is with the currently available immunizations for SARS-CoV-2,” said Dr. Isaacs. More questions to address include whether there are differences in the different products available, whether immunization after SARS-CoV-2 infection improves both seroconversion and immune reactivity, and whether there is any benefit to transiently stopping dual immune active therapy during the time of immunization, she said.

Further studies can fill knowledge gaps

“There is a knowledge gap in our understanding of susceptibility to SARS-CoV-2 infections among patients with IBD who have previously been infected,” Shirley Cohen-Mekelburg, MD, MS, staff physician and research scientist in the inflammatory bowel disease program at the Veterans Affairs Ann Arbor (Mich.) Healthcare System, said in an interview. ”This is a first step in beginning to narrow this gap – to provide patients and providers with data to drive recommendations during this COVID-19 pandemic.”

She added that, while further work needs to be done, the study findings do support potential benefit for ongoing vigilance among patients receiving infliximab for IBD. “The study findings also drive us to seek answers to more questions: For example, should we consider serological testing for patients on infliximab? How does the presence or absence of anti–SARS-CoV-2 antibodies associate with susceptibility to infection for patients with infliximab?

“Further studies examining anti–SARS-CoV-2 reactivity are necessary to better understand antibody responses between patients with IBD to the general population, or between patients on immunosuppressive therapy and the general population,” she said. “Observational studies are also not designed to examine the causal relationship between infections, medications, and antibody responses. There may be some inherent differences to patients who receive infliximab as compared to vedolizumab for IBD.”

The study was supported by Biogen (Switzerland), Celltrion Healthcare, Galapagos, F. Hoffmann-La Roche, Hull University Teaching Hospital NHS Trust, and the Royal Devon and Exeter NHS Foundation Trust. The study authors disclosed financial and nonfinancial relationships with numerous companies, including AbbVie, Biogen, Celltrion Healthcare, Galapagos, F. Hoffmann-La Roche, and Immundiagnostik, as well as Janssen, who markets infliximab, and Takeda, who markets vedolizumab. Dr. Isaacs and Dr. Cohen-Mekelburg had no relevant financial conflicts to disclose.
