The U.S. Preventive Services Task Force (USPSTF) announced on Tuesday that it is standing by its 2014 recommendations that sexually active girls and young women be screened for chlamydia and gonorrhea. But the panel is not ready to provide guidance about screening males even amid an outbreak of gonorrhea infections among men who have sex with men (MSM).

“For men in general, there’s not enough evidence to determine whether screening will reduce the risk of complications or spreading infections to others,” said Marti Kubik, PhD, RN, in an interview. Dr. Kubik is a professor at the George Mason University School of Nursing, Fairfax, Va., and is a member of the task force. “We need further research so we will know how to make those recommendations,” she said.

The screening recommendations for chlamydia and gonorrhea were published Sept. 14 in the Journal of the American Medical Association. The guidance is identical to the panel’s 2014 recommendations. The task force recommends screening for chlamydia and gonorrhea in all sexually active females aged 24 years or younger and in sexually active women aged 25 and older if they are at higher risk because of factors such as new or multiple sex partners.

“We continue to see rising rates of these infections in spite of consistent screening recommendations,” Dr. Kubik said. “In 2019, the CDC recorded nearly 2 million cases of chlamydia and a half million cases of gonorrhea. The big clincher is that chlamydia and gonorrhea can occur without symptoms. It’s critical to screen if we’re going to prevent serious health complications.”

The report notes that chlamydia and gonorrhea may lead to pelvic inflammatory disease in women and to multiple complications in infants born to infected mothers. Men can develop urethritis and epididymitis. Both diseases can boost the risk for HIV infection and transmission.

“We want clinicians to review the new recommendation and feel confident about the evidence base that supports a need for us to be screening young women and older women who are at increased risk,” Dr. Kubik said. She noted that almost two-thirds of chlamydia cases and more than half of gonorrhea cases occur in men and women aged 15-24.

Unlike the CDC, which recommends annual chlamydia and gonorrhea screening in appropriate female patients, the task force provides no guidance on screening frequency. “We didn’t have the evidence base to make a recommendation about how often to screen,” Dr. Kubik said. “But recognizing that these often occur without symptoms, it’s reasonable for clinicians to screen patients whose sexual history reveals new or consistent risk factors.”

Philip A. Chan, MD, an associate professor at Brown University, Providence, R.I., who directs a sexually transmitted disease clinic, told this news organization that he found it frustrating that the task force didn’t make recommendations about screening of MSM. According to a commentary accompanying the new recommendations, the rate of gonorrhea in MSM – 5,166 cases per 100,000, or more than 5% – is at a historic high.

In contrast to the task force, the CDC recommends annual or more frequent testing for gonorrhea and chlamydia plus HIV and syphilis in sexually active MSM.

Dr. Chan noted that the task force’s guidance “tends to be the most evidence-based recommendations that exist. If the evidence isn’t there, they usually don’t make a recommendation.” Still, he said, “I would argue that there’s good evidence that in MSM, the risk for HIV acquisition warrants routine screening.”

Jeanne Marrazzo, MD, MPH, director of the division of infectious diseases at the University of Alabama at Birmingham, also noted the limits of the task force’s insistence on certain kinds of evidence. Dr. Marrazzo, who coauthored a commentary that accompanies the recommendations, said in an interview that the panel’s “reliance on randomized-controlled-trial-level evidence tends to limit its ability to evolve their recommendations in a way that could account for evolving epidemiology or advances in our understanding of pathophysiology of these infections.”

Dr. Chan noted that obstacles exist for patients even when screening recommendations are in place. Although insurers typically cover costs of chlamydia and gonorrhea screening tests, he said, the uninsured may have to pay $100 or more each.

The USPSTF is supported by the U.S. Agency for Healthcare Research and Quality. Dr. Kubik, Dr. Chan, and Dr. Marrazzo report no relevant financial relationships.

As people begin to return to offices after working remotely, a new study suggests that clutter on the job is more than just an annoyance to neatniks. It might also be an indicator that employees are unhappy at work, especially if they have upper-level positions.

Researchers surveyed 202 office workers and linked higher perceived levels of clutter to less satisfaction/pleasure from work and more work-related burnout/tension. While the findings don’t confirm which came first – clutter or unhappiness on the job – they do suggest that the office work environment is more than an matter of appearances.

Study lead author Joseph R. Ferrari, PhD, a professor of psychology at DePaul University, Chicago, goes even further and suggests that clutter might undermine well-being. “If someone comes into [a therapist’s office] with lots of clutter, they probably have it at home and work, and it’s hindering their life,” Dr. Ferrari said in an interview. “Having a lot of clutter piles is really not a good thing. It makes you less effective.”

Dr. Ferrari has conducted several studies into clutter. He and colleagues launched the new study, published in the International Journal of Psychological Research and Reviews, to explore the impact of clutter at the office.

“The impact of clutter on employee well-being may affect profit, staff motivation, the buildup of slack/extraneous resources, interpersonal conflict, attitudes about work, and employee behavior,” Dr. Ferrari and colleagues wrote.

The researchers surveyed participants in 290 workers in 2019 and focused on 209 who worked in offices (60% were men, 87% were 45 years old or younger, 65% held a college or advanced degree, and 79% were White). Most were lower-level employees rather than higher-level employees with management responsibilities.

Both upper-and lower-level employees mentioned the same types of clutter most often – paper, office equipment, and trash, such as used coffee cups. The upper-level workers reported more problems with clutter, although this might be because they are more sensitive to it than lower-level workers, Dr. Ferrari said.

The researchers found that “office clutter was significantly negatively related to ... satisfaction/pleasure from work and significantly positively related to a risk for burnout/tension from work.” They also reported that “upper-level workers were significantly more likely to report clutter and being at risk for burnout/tension than lower-level workers.”

Specifically, a technique known as exploratory factor analysis determined that “63% of office clutter behavior can be explained by either satisfaction/pleasure with one’s work or risk for burnout,” Dr. Ferrari said. The findings suggest that clutter leads to negative feelings about work, not the other way around, he said.

The new study does not address whether clutter has positive attributes, as suggested by a 2013 report published in Psychological Science.

Darby Saxbe, PhD, an associate professor of psychology at the University of Southern California, Los Angeles, who studies work stress, said in an interview that it can be difficult to figure out the direction of causality in a study like this. “Someone who’s overwhelmed might generate more clutter and not have the bandwidth to put things away. If the space is really cluttered, you won’t be able to find things as effectively, or keep track of projects as well, and that will feed more feelings of stress and burnout.”

David Spiegel, MD, Willson Professor of psychiatry and behavioral sciences at Stanford (Calif.) University, agreed.

“The idea of clutter in the environment having a negative effect on mood is interesting, but it is equally likely that clutter reflects burnout, inability to complete tasks and dispose of their remnants,” he said in an interview. “There may be a relationship, and they may interact, but the direction is not clear,” said Dr. Spiegel, who is also director of Stanford’s Center on Stress and Health.

Still, he said, “in these days of Zoom therapy, observing clutter in a patient’s room or office may provide a hint about potential burnout and depression.”

No funding is reported. Dr. Ferrari, Dr. Saxbe, and Dr. Spiegel reported no disclosures.

A new study rebuts the conventional rheumatology wisdom about ankylosing spondylitis (AS) by reporting that actually there’s no gender gap in the prevalence of the disease. Researchers found no statistically significant difference in rates between men and women based on an analysis of military medical records.

“Our findings challenge the widely held belief that AS in the U.S. occurs substantially more frequently in males than females,” the study authors, led by data scientist D. Alan Nelson, PhD, of Stanford (Calif.) University, wrote in a study published Aug. 30 in Arthritis Care & Research.

The researchers launched the study to fill a gap in knowledge regarding case rates by gender. “The incidence of AS in the U.S. has been understudied and incompletely characterized,” they wrote.

Even though AS is fairly common, affecting an estimated 1% of the American adult population (2.5 million people), only one published population study has examined rates by gender in the United States. That study tracked cases in Minnesota’s Olmsted County during 1980-2009 and found that the ratio of cases in men vs. women was 3.8:1, which was “consistent with more recent estimates” at the time.

However, the population in that study in 1980 was 100% White, the authors of the new study note. A Canadian study that tracked an Ontario population from 1995 to 2010, meanwhile, suggested that AS rates among women were rising and the gender gap was shrinking. AS rates as a whole also nearly tripled, possibly because of more awareness.

For the new study, researchers retrospectively tracked 728,556 members of the U.S. military who underwent guideline-directed screening for back pain during 2014-2017. The study population was about 68% White, 22% Black, 5% Asian or Pacific Islander, and the remainder were other races or unknown. About 85% were male.

The subjects were monitored for a mean of 2.21 years, and 438 (0.06%) were diagnosed with AS at least once over that period.

The researchers found that the AS rates among males vs. females were similar (incidence rate ratio, 1.16; P = .23; adjusted odds ratio, 0.79; 95% confidence interval, 0.61-1.02; P = .072).

The researchers also found that Whites were more likely to develop AS than Blacks (aOR, 1.39; 95% CI, 1.01-1.66; P = .04).

The risk of AS increased with age, the researchers reported, with the odds growing sevenfold in the 45-and-older population vs. the under-24 population (aOR, 7.3; 95% CI, 5.7-10.3; P < .001).

The researchers noted that their study examined a more diverse population than the earlier Minnesota study. It’s also possible that the results of the two studies differed because of differences in definitions of AS diagnosis or imprecision in diagnosis codes, they wrote.

The researchers added that “the finding of a 1.21 male-female prevalence ratio of AS in the Canadian Ontario study was also generally consistent with our findings. Similar to our study population, the Canadian population was racially more diverse than the Olmsted study population at the times of both studies.”

Some limitations of the study include the fact that the military population is not a random sample and may have low rates of AS. “It is highly likely that most clinically evident cases of AS would have been screened out prior to enrollment in the military service,” they wrote. “Differences between military service members and the general population may explain why we observed a different association between AS incidence and age in comparison to that reported by prior studies. The increasing risk of AS with adult age that we observed could reflect selective discharge patterns related to very early symptoms of AS in this population.”

The study was funded in part by a grant from the Spondylitis Association of America. No information about potential conflicts of interest was provided in the manuscript.

The researchers found that the AS rates among males vs. females were similar (incidence rate ratio, 1.16; P = .23; adjusted odds ratio, 0.79; 95% confidence interval, 0.61-1.02; P = .072).

The researchers also found that Whites were more likely to develop AS than Blacks (aOR, 1.39; 95% CI, 1.01-1.66; P = .04).

The risk of AS increased with age, the researchers reported, with the odds growing sevenfold in the 45-and-older population vs. the under-24 population (aOR, 7.3; 95% CI, 5.7-10.3; P < .001).

The researchers noted that their study examined a more diverse population than the earlier Minnesota study. It’s also possible that the results of the two studies differed because of differences in definitions of AS diagnosis or imprecision in diagnosis codes, they wrote.

The researchers added that “the finding of a 1.21 male-female prevalence ratio of AS in the Canadian Ontario study was also generally consistent with our findings. Similar to our study population, the Canadian population was racially more diverse than the Olmsted study population at the times of both studies.”

Some limitations of the study include the fact that the military population is not a random sample and may have low rates of AS. “It is highly likely that most clinically evident cases of AS would have been screened out prior to enrollment in the military service,” they wrote. “Differences between military service members and the general population may explain why we observed a different association between AS incidence and age in comparison to that reported by prior studies. The increasing risk of AS with adult age that we observed could reflect selective discharge patterns related to very early symptoms of AS in this population.”

The study was funded in part by a grant from the Spondylitis Association of America. No information about potential conflicts of interest was provided in the manuscript.

The same genetic variations may boost susceptibility to both severe COVID-19 and cannabis use disorder (CUD), a new study suggests. The research does not confirm a genetic link, but the lead author said the signs of an association are still “troubling.”

“Reducing cannabis use among heavy users may potentially provide protection against severe COVID-19 presentations,” Alexander S. Hatoum, PhD, a postdoctoral scholar at Washington University, St. Louis, said in an interview. “Outside of individual risk, these data also have important implications for policy regarding vaccination as well as treatment prioritization in an overly taxed medical system.”

The study was published in the journal Biological Psychiatry Global Open Science.

Dr. Hatoum and colleagues launched the study to gain insight into whether CUD might be a risk factor for severe COVID-19 presentations.

As defined by the DSM-5, people with CUD suffer from impairment or distress because of their cannabis use and meet at least 2 of 11 criteria over a 12-month period, such as cravings, cannabis tolerance, and withdrawal symptoms. According to a 2020 study that examined 2008-2016 data, 2.72% of children aged 12-17 showed signs of CUD, as did 1.23% of those aged over 26.

The primary reasons for hospitalization and death related to COVID-19 are respiratory symptoms. “And we have observed that genetic vulnerability to CUD is shared with respiratory disease, even after tobacco use is considered,” Dr. Hatoum said.

He and his colleagues examined data from genomewide association studies and searched for genetic correlations between CUD (14,080 cases, 343,726 controls) and COVID-19 hospitalization (9,373 cases, 1,197,256 controls). “Genetic vulnerability to COVID-19 was correlated with genetic liability to CUD (P = 1.33e^–6),” the researchers wrote. “This association remained when accounting for genetic liability to related risk factors and covariates (P = .012-.049).”

According to Dr. Hatoum, the researchers found inconclusive evidence that CUD might worsen COVID-19 cases. “We applied statistical causal models, which found an effect consistent with causality, but it was nonsignificant,” he said.

Despite the absence of causality, the study findings could prove useful for clinicians and policy makers.

“Those struggling with CUD may be prioritized for vaccination and vaccination boosters to mitigate their higher likelihood of a severe COVID-19 presentation,” Dr. Hatoum said. “When testing positive for COVID-19, they may also be prioritized for earlier treatment.”

The study authors also added that the findings “urge caution” in regard to the wave of U.S. states legalizing cannabis. “Our data suggest that heavy cannabis use, but not lifetime cannabis use, represents a risk factor for severe COVID-19 presentations,” Dr. Hatoum said.

In an interview, Danielle Dick, PhD, who was not involved with the study, said it applies “cutting-edge methods to an important research question” and offers a “hint” of a genetic risk factor that makes some people more likely to be hospitalized for COVID-19. However, “the study does not tell us what those underlying genetically influenced processes might be,” added Dr. Dick, professor of psychology, and human and molecular genetics at Virginia Commonwealth University, Richmond. “And it’s an important caveat to point out that the results from this study are limited in that they are based on data from people from European descent – so they can’t necessarily be applied to address the harm experienced by so many people of color from the COVID pandemic. That’s an unfortunate limitation.”

As for the idea that the study findings should prompt caution about marijuana legalization, Dr. Dick said it’s true that increased acceptability of drug use “increases the likelihood that individuals who are genetically vulnerable will develop problems. There is robust evidence of this.”

However, Dr. Dick said, “the legalization of marijuana is a complex topic because the health consequences aren’t the only consideration when it comes to legalization. The other side of the coin is the huge harm that has been caused to communities of color through marijuana criminalization. Legalization will hopefully lead to decreased harm on that front. So it’s a double-edged sword.”

Childhood exposure to parental smoking appears to greatly boost the risk of confirmed cases of rheumatoid arthritis in adult women, although the overall rate is small, a new study reports. The findings, published Aug. 18, 2021, in Arthritis & Rheumatology, follows other evidence that early second-hand smoke exposure can trigger lifelong damage to the immune system.

“We estimated that there is 75% increased risk of adult seropositive RA due to the direct impact of childhood parental smoking,” said study lead author and Brigham & Women’s Hospital epidemiologist Kazuki Yoshida, MD, ScD, referring to an adjusted analysis conducted in the study. “Passive smoking is likely harmful throughout an individual’s life course regarding rheumatoid arthritis but potentially more harmful during the childhood period.”

The researchers launched the study to fill an evidence gap, Dr. Yoshida said in an interview. “Active smoking is a well-established risk factor for RA. However, studies on passive smoking’s impact on RA are sparse, and few studies had a well-characterized cohort of participants with comprehensive data of passive smoking during life course – in utero exposure, childhood exposure, adult exposure – and chart review–adjudicated RA outcomes.”

The study authors retrospectively tracked 90,923 subjects who joined the Nurses’ Health Study II in 1989 when they were aged 25-42. At the study’s start, the average age of subjects was 34.5, 93% were White, and 98% were premenopausal. Almost two-thirds had never smoked themselves, and 65% said their parents had smoked during their childhoods.

Of the subjects, the researchers found that 532 were identified as having RA over a median follow-up period of 27.7 years. Two-thirds of those cases (n = 352) were confirmed as seropositive by clinical testing.

The study linked maternal smoking during pregnancy to confirmed RA in adulthood via a confounder-adjusted analysis (hazard ratio, 1.25; 95% confidence interval, 1.03-1.52), but the connection vanished after researchers adjusted their statistics to reflect possible influences by later exposures to smoke.

After adjustment for confounders, the study linked childhood exposure to parental smoking to a 41% in increase in risk of confirmed adulthood RA (HR, 1.41; 95% CI, 1.08-1.83). A controlled direct effect analysis boosted the excess risk to 75% (HR, 1.75; 95% CI, 1.03-2.98).

This analysis reveals that “childhood parental smoking seems to be associated with adult rheumatoid arthritis beyond what is explained by the fact that childhood passive smoking can promote personal smoking uptake, a known risk factor for rheumatoid arthritis,” Dr. Yoshida said.

The overall rate of RA in the study population – roughly 0.6% – aligns with risk levels in the general population, he said. As a result, “the absolute risk increase may not be extremely high. But the concept that early life exposure may affect immunological health later in life is important.”

Potential pathophysiological mechanisms

Why might parental smoking boost the risk of RA? Exposure to secondhand smoke may irritate the lungs and cause abnormal proteins to form, Dr. Yoshida said. “The immune system produces antibodies in an attempt to attack such abnormal proteins. This immune reaction can spread to other body sites and attack normal tissues, including the joints.”

In addition, “smoking increases the risk of infections, which could in turn increase the risk of RA. Smoking is also known to result in epigenetic changes which could trigger RA in susceptible people,” University of California, San Francisco, autoimmune disease epidemiologist Milena A. Gianfrancesco, PhD, MPH, said in an interview. She cowrote a commentary accompanying the new study.

Other studies have linked smoking exposure to autoimmune disorders. Earlier this year, researchers who tracked 79,806 French women reported at the EULAR 2021 annual meeting that they found a link between exposure to second-hand smoking during childhood or adulthood and higher rates of RA.

Dr. Yoshida and colleagues noted their study’s limitations, including the inability to track cases of RA in subjects up to the age when they entered the nurses research project. Also, only one questionnaire over the entire period of the Nurses’ Health Study II asks subjects about whether they were exposed to secondhand smoke as adults.

The study also says nothing about whether a similar risk exists for males, and the nurse subjects are overwhelmingly White.

Still, Dr. Gianfrancesco praised the study and said it relies on extensive data and strong statistical methods. “The findings are important because they drive home the importance of reducing cigarette smoke exposure to reduce risk of disease,” she said. “They highlight the need to not only focus on one’s personal smoking habits, but also other sources of secondhand smoke exposure.”

She added that children with a family history of RA or other autoimmune diseases are especially vulnerable to the effects of secondhand smoke because they may be more susceptible to developing the diseases themselves. “Rheumatologists and other health care providers should be sure to discuss the risks of smoking with their patients, as well as the risk of secondhand smoke,” she said. “And parents should keep their children away from secondhand smoke in the home or other environments in which smoke is prevalent, such as the home of another caregiver or a workplace if the child accompanies their parent to work.”

The study was funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the Rheumatology Research Foundation, and the National Institutes of Health. The study and commentary authors, including Dr. Yoshida and Dr. Gianfrancesco, reported having no relevant disclosures.

Double-dose vaccination against SARS-CoV-2 in patients with rheumatic and musculoskeletal diseases (RMDs) doesn’t appear to boost the risk of flares, a new study shows. The risk of adverse effects after vaccination is high, just as it is in the general population, but no patients experienced allergic reactions.

“Our findings suggest that COVID-19 vaccines are safe in patients with rheumatic and musculoskeletal diseases. Overall, rates of flare are low and mild, while local and systemic reactions should be anticipated,” lead author Caoilfhionn Connolly, MD, MSc, a rheumatology fellow at Johns Hopkins University, Baltimore, said in an interview. “Many of our patients are at increased risk of severe infection and or complications from COVID-19. It has been shown that patients with RMDs are more willing to reconsider vaccination if it is recommended by a physician, and these data should help inform these critical discussions.”

The study appeared Aug. 4 in Arthritis & Rheumatology.

According to Dr. Connolly, the researchers launched their study to better understand the effect of two-dose SARS-CoV-2 messenger RNA vaccinations authorized for emergency use by the Food and Drug Administration (Pfizer and Moderna vaccines) on immunosuppressed patients. As she noted, patients with RMDs were largely excluded from vaccine trials, and “studies have shown that some patients with RMDs are hesitant about vaccination due to the lack of safety data.”

Some data about this patient population have started to appear. A study published July 21 in Lancet Rheumatology found that patients with systemic lupus erythematosus (SLE) reported few flares within a median of 3 days after receiving one or two doses of various COVID-19 vaccines. Side effects were common but were mainly mild or moderate.

For the new study, researchers surveyed 1,377 patients with RMDs who’d received two vaccination doses between December 2020 and April 2021. The patients had a median age of 47, 92% were female, and 10% were non-White. The patients had a variety of RMDs, including inflammatory arthritis (47%), SLE (20%), overlap connective tissue disease (20%), and Sjögren’s syndrome and myositis (each 5%).

A total of 11% said they’d experienced a flare that required treatment, but none were severe. In comparison, 56% of patients said they had experienced a flare of their RMD in the 6 months prior to their first vaccine dose. Several groups had a greater likelihood of flares, including those who’d had COVID-19 previously (adjusted incidence rate ratio [IRR], 2.09; P = .02). “COVID-19 can cause both acute and delayed inflammatory syndromes through activation of the immune system,” Dr. Connolly said. “Vaccination possibly triggered further activation of the immune system resulting in disease flare. This is an area that warrants further research.”

Patients who took combination immunomodulatory therapy were also more likely to flare after vaccination (IRR, 1.95; P < .001). And patients were more likely to report flares after vaccination if they experienced a flare in the 6 months preceding vaccination (IRR, 2.36; P < .001). “This may suggest more active disease at baseline,” Dr. Connolly said. “It is difficult to differentiate whether these patients would have experienced flare even without the vaccine.”

A number of factors didn’t appear to affect the likelihood of flares: gender, age, ethnicity, type of RMD, and type of vaccine.

Local and systemic side effects were frequently reported, including injection site pain (87% and 86% after first and second doses, respectively) and fatigue (60% and 80%, respectively). As is common among people receiving COVID-19 vaccines, side effects were more frequent after the second dose.

As for future research, “we are evaluating the long-term safety and efficacy of the COVID-19 vaccines in patients with RMDs,” study coauthor Julie J. Paik, MD, assistant professor of medicine at Johns Hopkins, said in an interview. “We are also evaluating the impact of changes in immunosuppression around vaccination.”

The study was funded by the Ben-Dov family and grants from several institutes of the National Institutes of Health. Dr. Connolly and Dr. Paik reported no relevant disclosures. Other study authors reported various financial relationships with pharmaceutical companies.

Double-dose vaccination against SARS-CoV-2 in patients with rheumatic and musculoskeletal diseases (RMDs) doesn’t appear to boost the risk of flares, a new study shows. The risk of adverse effects after vaccination is high, just as it is in the general population, but no patients experienced allergic reactions.

“Our findings suggest that COVID-19 vaccines are safe in patients with rheumatic and musculoskeletal diseases. Overall, rates of flare are low and mild, while local and systemic reactions should be anticipated,” lead author Caoilfhionn Connolly, MD, MSc, a rheumatology fellow at Johns Hopkins University, Baltimore, said in an interview. “Many of our patients are at increased risk of severe infection and or complications from COVID-19. It has been shown that patients with RMDs are more willing to reconsider vaccination if it is recommended by a physician, and these data should help inform these critical discussions.”

The study appeared Aug. 4 in Arthritis & Rheumatology.

According to Dr. Connolly, the researchers launched their study to better understand the effect of two-dose SARS-CoV-2 messenger RNA vaccinations authorized for emergency use by the Food and Drug Administration (Pfizer and Moderna vaccines) on immunosuppressed patients. As she noted, patients with RMDs were largely excluded from vaccine trials, and “studies have shown that some patients with RMDs are hesitant about vaccination due to the lack of safety data.”

Some data about this patient population have started to appear. A study published July 21 in Lancet Rheumatology found that patients with systemic lupus erythematosus (SLE) reported few flares within a median of 3 days after receiving one or two doses of various COVID-19 vaccines. Side effects were common but were mainly mild or moderate.

For the new study, researchers surveyed 1,377 patients with RMDs who’d received two vaccination doses between December 2020 and April 2021. The patients had a median age of 47, 92% were female, and 10% were non-White. The patients had a variety of RMDs, including inflammatory arthritis (47%), SLE (20%), overlap connective tissue disease (20%), and Sjögren’s syndrome and myositis (each 5%).

A total of 11% said they’d experienced a flare that required treatment, but none were severe. In comparison, 56% of patients said they had experienced a flare of their RMD in the 6 months prior to their first vaccine dose. Several groups had a greater likelihood of flares, including those who’d had COVID-19 previously (adjusted incidence rate ratio [IRR], 2.09; P = .02). “COVID-19 can cause both acute and delayed inflammatory syndromes through activation of the immune system,” Dr. Connolly said. “Vaccination possibly triggered further activation of the immune system resulting in disease flare. This is an area that warrants further research.”

Patients who took combination immunomodulatory therapy were also more likely to flare after vaccination (IRR, 1.95; P < .001). And patients were more likely to report flares after vaccination if they experienced a flare in the 6 months preceding vaccination (IRR, 2.36; P < .001). “This may suggest more active disease at baseline,” Dr. Connolly said. “It is difficult to differentiate whether these patients would have experienced flare even without the vaccine.”

A number of factors didn’t appear to affect the likelihood of flares: gender, age, ethnicity, type of RMD, and type of vaccine.

Local and systemic side effects were frequently reported, including injection site pain (87% and 86% after first and second doses, respectively) and fatigue (60% and 80%, respectively). As is common among people receiving COVID-19 vaccines, side effects were more frequent after the second dose.

Five of the more uncommon dermatologic disorders – sarcoidosis, Rosai-Dorfman disease, Erdheim-Chester disease, eosinophilic fasciitis, and cutaneous Crohn disease – are linked to internal diseases and may spawn misdiagnoses, a dermatologist told colleagues.

“Proper diagnosis can lead to an effective management in our patients,” said Jeffrey Callen, MD, professor of medicine and chief of dermatology at the University of Louisville (Ky.), who spoke at the Inaugural Symposium for Inflammatory Skin Disease.
 

Sarcoidosis

The cause of sarcoidosis, an inflammatory disease that tends to affect the lungs, “is unknown, but it’s probably an immunologic disorder,” Dr. Callen said, “and there probably is a genetic predisposition.” About 20%-25% of patients with sarcoidosis have skin lesions that are either “specific” (a biopsy that reveals a noncaseating – “naked” – granuloma) or “nonspecific” (most commonly, erythema nodosum, or EN).

The specific lesions in sarcoidosis may occur in parts of the body, such as the knees, which were injured earlier in life and may have taken in foreign bodies, Dr. Callen said. As for nonspecific lesions, about 20% of patients with EN have an acute, self-limiting form of sarcoidosis. “These patients will have bilateral hilar lymphadenopathy, anterior uveitis, and polyarthritis. It’s generally treated symptomatically because it goes away on its own.”

He cautioned colleagues to beware of indurated, infiltrative facial lesions known as lupus pernio that are commonly found on the nose. They’re more prevalent in Black patients and possibly women, who are at higher risk of manifestations outside the skin, he said. “If you have it along the nasal rim, you should look into the upper respiratory tract for involvement.”

Dr. Callen recommends an extensive workup in patients with suspected sarcoidosis, including biopsy (with the exception of EN lesions), cultures and special stains, and screening when appropriate, for disease in organs such as the eyes, lungs, heart, and kidneys.

As for treatment, “the disease is in the dermis, and some topical therapies are not highly effective,” he said. There are injections that can be given, including corticosteroids, and there are a variety of oral treatments that are all off label.” These include corticosteroids, antimalarials, allopurinol, and tetracyclines, among several others. Subcutaneous and intravenous treatments are also options, along with surgery and laser therapy to treat specific lesions.

Rosai-Dorfman disease

This rare disorder is caused by overproduction of certain white blood cells in the lymph nodes, which can cause nodular lesions. The disease most often appears in children and young adults, often Black individuals and males. It is fatal in as many as 11% of patients, justifying aggressive treatment in patients with aggressive disease, Dr. Callen said. When it’s limited to the skin, however, “nothing may need to be done.”

Dr. Callen highlighted consensus recommendations about diagnosis and treatment of Rosai-Dorfman disease published in 2018.

He also noted the existence of cutaneous Rosai-Dorfman disease, a “solitary process” that appears more commonly in females, and in people of Asian heritage, compared with White individuals. It is characterized by single, clustered or widespread lesions: They can be xanthomatous, erythematous, or red-brown papules, nodules, and plaques. They’re acneiform, pustular, giant granuloma annulare–like, subcutaneous, and vasculitis-like, he said.

While Rosai-Dorfman disease can be linked to lymphoma, hypothyroidism, and lupus erythematosus, “nothing necessarily needs to be done when it’s skin-limited since it can be self-resolving,” he noted. Other treatments include radiotherapy, cryotherapy, excision, topical and oral corticosteroids, thalidomide, and methotrexate.

The disease can be serious, and is fatal in 5% of cases. When a vital organ is threatened, Dr. Callen suggested surgery, chemotherapy, or radiation.
 

Erdheim-Chester disease

This disease – which is extremely rare, with just 500 cases noted before 2014 – occurs when the body overproduces macrophages. It’s most common in middle-aged people and in men, who make up 75% of cases. About a quarter of patients develop skin lesions: Red-brown to yellow nodules and xanthelasma-like indurated plaques on the eyelids, scalp, neck, trunk, and axillae, and “other cutaneous manifestations have been reported in patients,” Dr. Callen said.

The disease also frequently affects the bones, large vessels, heart, lungs, and central nervous system. Interferon-alpha is the first-line treatment, and there are several other alternative therapies, although 5-year survival (68%) is poor, and it is especially likely to be fatal in those with central nervous system involvement.
 

Eosinophilic fasciitis

Eosinophilic fasciitis (EF) “is a disorder of unknown etiology that causes sclerosis of the skin” without Raynaud’s phenomenon, Dr. Callen said. Look for erythema, swelling, and induration of the extremities that is accompanied by peripheral eosinophilia, and if necessary, confirm the diagnosis with full skin-to-muscle biopsy or MRI.

There are many possible triggers, including strenuous exercise, initiation with hemodialysis, radiation therapy and burns, and graft-versus-host disease. Other potential causes include exposure to medications such as statins, phenytoin, ramipril, subcutaneous heparin, and immune checkpoint inhibitor therapy. The disorder is also linked to autoimmune and hematologic disorders.

Dr. Callen, who highlighted EF guidelines published in 2018, said treatments include physical therapy, prednisone, methotrexate, mycophenolate, and hydroxychloroquine.
 

Metastatic Crohn’s disease

This is a rare granulomatous inflammation of skin that often affects the genitals, especially in children. It is noncontiguous with the GI tract, and severity of skin involvement does not always parallel the severity of the disease in the GI tract, Dr. Callen said. However, the condition can occur before or simultaneously with the development of GI disease, or after GI surgery.

He highlighted a review of metastatic Crohn’s disease, published in 2014, and noted that there are multiple treatments, including systemic corticosteroids, tumor necrosis factor–alpha inhibitors, and topical therapies.

Dr. Callen reported no relevant disclosures.

Violin and viola players can pay a price for the music they create: Many suffer from skin irritation and inflammation where the instruments touch their necks and upper bodies. Now, a new literature review offers insight into this common condition, known as “fiddler’s neck.”

Hill Street Studios/Stone/Getty Images

“These skin conditions are disfiguring, and they also carry so much psychological burden. Not only are these patients under constant pressure to perform at their maximum at all times, it really is troublesome when there is a barrier between you and performing art that you absolutely love,” lead author Henry Lim, an osteopathic medical student at the University of North Texas Health Science Center at Fort Worth, said in an interview.

The results of the literature review were presented in a poster at the Inaugural Symposium for Inflammatory Skin Disease.

Mr. Lim, who has a special interest in skin, said his own musical experience inspired the research. “Throughout my experience as a violinist, I faced many dermatologic issues because of my violin, and it affected my performance,” he said. “As time went on, I recognized that many other stringed instrumentalists were dealing with similar issues but chose to live with it because it came with the territory.”

One physician told Mr. Lim that he needed to quit in order to permanently treat his skin problems. He didn’t accept this answer and instead launched the literature review with colleagues Marshall Hall, MPH, also an osteopathic medical student with an interest in dermatology, and Sajid Surve, DO, codirector of the UNT Texas Center for Performing Arts Health.

Mr. Lim and colleagues evaluated 23 articles, which included case studies and literature reviews, about dermatitis in violinists, violists, cellists, bassists, guitarists and harpists. “Stringed instrumentalists are the highest at-risk population compared to performers who play other types of instruments,” Mr. Lim said.

The poster he presented at the meeting largely focuses on fiddler’s neck, which he defined as “simply dermatitis related to friction and allergic irritation from playing violin or viola.” Many people, he noted, are allergic to nickel, and the bracket that secures the violin’s chin rest “most often contains nickel. Even a very small concentration of nickel can cause massive reactions, and we found that the C string of a viola – the thickest, lowest-sounding string – contains a nickel concentration of up to 37%.”

Gold-coated strings are an alternative option, he said, but they’re more expensive.

Stringed instrumentalists may also be allergic to rosin applied to “bow hairs,” which is the hair – typically from horses – that is used to string bows, also described in the poster. “We found that there is an overall common allergy to the main ingredient called colophony,” Mr. Lim said. The legendary violin maker Antonio Stradivari “was rumored to have used colophony and another irritating ingredient called propolis in the wood varnish of his instruments. Because he was such a great influence on the art of violin crafting, his technique is still used in the modern era, which may be another contributing factor to the allergic reactions seen in stringed instrumentalists.”

(In the poster, the authors refer to one of the articles in the review, which described a violin maker allergic to colophony and propolis, who was treated with cetirizine, mild corticosteroids, and avoidance.)

What should dermatologists know about skin conditions in these musicians? Mr. Hall, one of the coauthors of the report, suggested they invite the patients to play their instruments during a visit. “The musicians may not understand that they are doing certain things with their movements, but looking from a clinical lens, we are able to see how their biomechanics and posture [are] contributing to their dermatitis,” he said.

Dr. Surve, the other coauthor, also suggested speaking to the patient’s teacher, coach, or mentor. “Keeping that person in the loop regarding what you are seeing and recommending will go a long way towards helping your patient,” he said. “If the teacher doesn’t understand or agree with what you’re trying to accomplish, they may try to undermine your plan of care. But if they are on board, they become a valuable tool for facilitating and reinforcing it.”

As for treatments, avoidance of the instruments is the most effective, but is simply not feasible for many musicians. “Certain interventions like creating a barrier between the musician and the instrument can reduce the risk of contact dermatitis without compromising the quality [of playing] as much,” Mr. Hall said. The poster reported that a handkerchief was used for this purpose in one case attributed to nickel sulfate in a 16-year-old .

Purchasing more expensive instrument materials to prevent reactions is another option, he said, and players can also purchase stands. But musicians may be resistant to any treatment that changes how the instruments sound or forces them to adjust the way they do things, he cautioned.

No funding for the study or author disclosures were reported.

Because he was such a great influence on the art of violin crafting, his technique is still used in the modern era, which may be another contributing factor to the allergic reactions seen in stringed instrumentalists.”

(In the poster, the authors refer to one of the articles in the review, which described a violin maker allergic to colophony and propolis, who was treated with cetirizine, mild corticosteroids, and avoidance.)

What should dermatologists know about skin conditions in these musicians? Mr. Hall, one of the coauthors of the report, suggested they invite the patients to play their instruments during a visit. “The musicians may not understand that they are doing certain things with their movements, but looking from a clinical lens, we are able to see how their biomechanics and posture [are] contributing to their dermatitis,” he said.

Dr. Surve, the other coauthor, also suggested speaking to the patient’s teacher, coach, or mentor. “Keeping that person in the loop regarding what you are seeing and recommending will go a long way towards helping your patient,” he said. “If the teacher doesn’t understand or agree with what you’re trying to accomplish, they may try to undermine your plan of care. But if they are on board, they become a valuable tool for facilitating and reinforcing it.”

As for treatments, avoidance of the instruments is the most effective, but is simply not feasible for many musicians. “Certain interventions like creating a barrier between the musician and the instrument can reduce the risk of contact dermatitis without compromising the quality [of playing] as much,” Mr. Hall said. The poster reported that a handkerchief was used for this purpose in one case attributed to nickel sulfate in a 16-year-old .

Purchasing more expensive instrument materials to prevent reactions is another option, he said, and players can also purchase stands. But musicians may be resistant to any treatment that changes how the instruments sound or forces them to adjust the way they do things, he cautioned.

Violin and viola players can pay a price for the music they create: Many suffer from skin irritation and inflammation where the instruments touch their necks and upper bodies. Now, a new literature review offers insight into this common condition, known as “fiddler’s neck.”

“These skin conditions are disfiguring, and they also carry so much psychological burden. Not only are these patients under constant pressure to perform at their maximum at all times, it really is troublesome when there is a barrier between you and performing art that you absolutely love,” lead author Henry Lim, an osteopathic medical student at the University of North Texas Health Science Center at Fort Worth, said in an interview.

The results of the literature review were presented in a poster at the Inaugural Symposium for Inflammatory Skin Disease.

Mr. Lim, who has a special interest in skin, said his own musical experience inspired the research. “Throughout my experience as a violinist, I faced many dermatologic issues because of my violin, and it affected my performance,” he said. “As time went on, I recognized that many other stringed instrumentalists were dealing with similar issues but chose to live with it because it came with the territory.”

One physician told Mr. Lim that he needed to quit in order to permanently treat his skin problems. He didn’t accept this answer and instead launched the literature review with colleagues Marshall Hall, MPH, also an osteopathic medical student with an interest in dermatology, and Sajid Surve, DO, codirector of the UNT Texas Center for Performing Arts Health.

Mr. Lim and colleagues evaluated 23 articles, which included case studies and literature reviews, about dermatitis in violinists, violists, cellists, bassists, guitarists and harpists. “Stringed instrumentalists are the highest at-risk population compared to performers who play other types of instruments,” Mr. Lim said.

The poster he presented at the meeting largely focuses on fiddler’s neck, which he defined as “simply dermatitis related to friction and allergic irritation from playing violin or viola.” Many people, he noted, are allergic to nickel, and the bracket that secures the violin’s chin rest “most often contains nickel. Even a very small concentration of nickel can cause massive reactions, and we found that the C string of a viola – the thickest, lowest-sounding string – contains a nickel concentration of up to 37%.”

Gold-coated strings are an alternative option, he said, but they’re more expensive.

Stringed instrumentalists may also be allergic to rosin applied to “bow hairs,” which is the hair – typically from horses – that is used to string bows, also described in the poster. “We found that there is an overall common allergy to the main ingredient called colophony,” Mr. Lim said. The legendary violin maker Antonio Stradivari “was rumored to have used colophony and another irritating ingredient called propolis in the wood varnish of his instruments.

Treating the needs of patients of color requires an understanding of differences that may not be readily apparent, a dermatologist told colleagues. For example, clinicians generally understand what White patients are talking about when they mention acne scarring, but Black patients have a different perception of the term that may be misinterpreted in the doctor’s office.

“Scarring is not usually what they’re talking about, although they may have some of that as well. They’re [typically] talking about what we know as postinflammatory hyperpigmentation, not scarring. So right away, you have to clarify,” Amy McMichael, MD, professor and chair of dermatology at Wake Forest Baptist Medical Center in Winston-Salem, N.C., said in a presentation at the Inaugural Symposium for Inflammatory Skin Disease. “When you’re talking about scarring, do you mean the dark spots? What exactly are you concerned about?”

Dr. McMichael highlighted a 2014 study that reported the results of a survey of 208 women (51% were White; 49% were non-White), which included 51 Black, 23 Hispanic, and 16 Asian women aged 25-45 (mean age, 35) with 25 or more lesions. White women were more troubled by facial acne than were women of color (89% vs. 76%, respectively, P < .05), and they were more likely to say lesion clearance was most important to them (58% vs. 32%, respectively, P < .001).

Meanwhile, non-White women were much more likely than were White women to say that clearance of postinflammatory hyperpigmentation was most important to them (42% vs. 8%, respectively, P < .0001).

“Seventy percent of [non-White women] felt that their race and ethnicity required targeted attention [in treatment], and two-thirds desired acne treatment that was designed to meet the needs of their skin type,” Dr. McMichael said. “If you don’t address the issues, if you don’t talk about the pigmentation with them or explain how you’re going to address it, people don’t feel heard. They don’t feel like they’ve really seen a dermatologist who understands their needs.”

She added that it’s crucial to ask about over-the-counter products. “If you don’t discuss them, they’ll assume that what they’re doing is okay.” She warns her patients against using and exposing their skin and face to cocoa butter and oils such as tea tree oil.

Research has suggested that among people of color, Blacks and Hispanics are most likely to experience dyspigmentation and scarring, Dr. McMichael said. She advised colleagues to be aware of pomade acne in these two groups of patients. Pomade acne appears along the hair line and is caused by the use of hair products. She also cautioned about acne cosmetica, which can be triggered by products such as makeup, used to cover up acne and postinflammatory hyperpigmentation.

As for acne treatments, Dr. McMichael highlighted a long list of familiar topical and oral agents and procedural options. Less familiar strategies include laser and light-based therapies, she said.

As for up-and-coming options, she pointed to topical minocycline, “which allows us to use an anti-inflammatory agent topically rather than orally when we’re trying to get away from using a lot of oral antibiotics.”

Also consider whether female patients have polycystic ovary syndrome, she said. “Then you might consider spironolactone. I certainly use a lot more of that these days to try to avoid long-term oral antibiotics.”

She recommended earlier use of isotretinoin in patients overall, and she urged colleagues to proceed with their standard retinoid approaches. However, she noted that she lets patients know that she’ll focus first on treating the acne itself and then work on the dark spots in later treatments. “If you give people a bleaching agent in the beginning, they’re going to stop using their main products, and they’re going to chase those dark spots. That’s just something that they can’t help doing.”

Dr. McMichael disclosed investigator and consultant relationships with multiple drug makers.

Pyoderma gangrenosum (PG), a rare and painful ulcerative skin disorder, requires special care because “it’s a challenging diagnosis to make” and is frequently linked to serious comorbid conditions, a dermatologist told colleagues.

PG is also challenging to manage, said Jeffrey Callen, MD, professor and chief of the division of dermatology at the University of Louisville (Ky.), who spoke at the Inaugural Symposium for Inflammatory Skin Disease. “There are multiple treatments, but few have a high level of evidence to document their efficacy.”

PG is a neutrophilic dermatosis that usually occurs with a small lesion, often pustular, that spreads, and is a diagnosis of exclusion. “There’s no way you can possibly exclude everything, but the major things that have to be excluded are infection and malignancies,” he said. “Doing a good history and physical examination is critical, and a biopsy should be done in the vast majority of patients.”

Cultures and routine labs should be obtained, said Dr. Callen, highlighting tests that measure immunofixation (IFE), antineutrophil cytoplasmic antibodies (ANCE), anticardiolipin antibody (aCL), and lupus anticoagulant (LA).

Bowel and bone marrow tests may be appropriate in some patients, he said, noting that about half of PG cases are linked to comorbid conditions such as inflammatory bowel disease (IBD), arthritis, and hematologic diseases.

Dr. Callen also made the following points about making the diagnosis:

• Several clinical variants exist: classic, peristomal, and atypical.
• Pathergy – hyperreactivity of skin to injury – occurs in about a third of patients.
• Neutrophilic infiltrates may occur in other organs.
• Numerous drugs, including isotretinoin, can cause PG.
• PG may be misdiagnosed as necrotizing fasciitis.
• Several diagnostic frameworks exist: the Su Criteria, the PARACELCUS Score, and the Delphi Consensus Criteria. The Delphi criteria identified the highest percentage of cases (89%) in a study comparing the three, published in 2020. The frameworks “are helpful in the clinic, but they are not to be used as criteria for diagnosis. They’re really for classification,” Dr. Callen said.

Once the diagnosis has been made, he said, focus on healing the wound, which he said “can be done as any other wound would be healed,” and calming the inflammation.

“Patients who have mild disease might be treated with lower doses of prednisone, topical medications, or intralesional injections,” he said. “Corticosteroids are never wrong in the beginning.” Some patients may have genetic abnormalities related to PG, he added, and medications that target them may be appropriate.

Antibiotics and biologic agents, particularly TNF-alpha inhibitors, are possible treatments, Dr. Callen said. He highlighted a 2018 systematic review that evaluated treatments and found the most evidence supported systemic corticosteroids, cyclosporine, and TNF-alpha inhibitors. However, the quality of studies was limited, and the authors noted that the lesions frequently failed to respond or recurred.

When appropriate, surgery can be performed, he said.
