In a study of adults, an increase of 1 g in estimated 24-hour urinary sodium excretion was associated with 11% higher odds of an atopic dermatitis (AD) diagnosis, 16% higher odds of having active AD, and 11% higher odds of increased severity of AD.

Those are key findings from a cross-sectional analysis of data from the United Kingdom.

“Excessive dietary sodium, common in fast food, may be associated with AD,” corresponding author Katrina Abuabara, MD, MA, MSCE, and colleagues wrote in the study, which was published online in JAMA Dermatology. They referred to recent research using sodium MRI, which showed that “the majority of the body’s exchangeable sodium is stored in the skin and that skin sodium is associated with autoimmune and chronic inflammatory conditions, including AD.” And in another study published in 2019, lesional skin sodium was 30-fold greater in patients with AD than in healthy controls.

To investigate whether there is an association between higher levels of sodium consumption and AD prevalence, activity, and severity at the population level, Dr. Abuabara, of the program for clinical research in the Department of Dermatology at the University of California, San Francisco, and coauthors drew from the UK Biobank, a population-based cohort of more than 500,000 individuals aged 37-73 years at the time of recruitment by the National Health Service. The primary exposure was 24-hour urinary sodium excretion, which was calculated by using the INTERSALT equation, a sex-specific estimation that incorporates body mass index; age; and urine concentrations of potassium, sodium, and creatinine. The primary study outcome was AD or active AD based on diagnostic and prescription codes from linked electronic medical records. The researchers used multivariable logistic regression models adjusted for age, sex, race and ethnicity, Townsend deprivation index, and education to measure the association.

Of the 215,832 Biobank participants included in the analysis, 54% were female, their mean age was 57 years, 95% were White, their mean estimated 24-hour urine sodium excretion was 3.01 g/day, and 10,839 (5%) had a diagnosis of AD. The researchers observed that on multivariable logistic regression, a 1-g increase in estimated 24-hour urine sodium excretion was associated with increased odds of AD (adjusted odds ratio [AOR], 1.11; 95% CI, 1.07-1.14), increased odds of active AD (AOR, 1.16; 95% CI, 1.05-1.28), and increased odds of increasing severity of AD (AOR, 1.11; 95% CI, 1.07-1.15).
 

Validating Results With US Data

To validate the findings, the researchers evaluated a cohort of 13,014 participants from the US-based National Health and Nutrition Examination Survey (NHANES), using pooled data from the 1999-2000, 2001-2002, and 2003-2004 samples. Of the 13,014 participants, 796 reported current AD, and 1493 reported AD in the past year. The mean dietary sodium intake of overall NHANES participants estimated with 24-hour dietary recall questionnaires was 3.45 g, with a mean of 3.47 g for those with current AD and a mean of 3.44 g for those without AD.

The researchers observed that a 1-g/day higher dietary sodium intake was associated with a higher risk for current AD (AOR, 1.22; 95%CI, 1.01-1.47) and a somewhat higher risk for AD in the past year (AOR, 1.14; 95% CI, 0.97-1.35).

“Future work should examine whether variation of sodium intake over time might trigger AD flares and whether it helps to explain heterogeneity in response to new immunomodulatory treatments for AD,” the authors wrote. “Reduced sodium intake was recommended as a treatment for AD more than a century ago, but there have yet to be studies examining the association of dietary sodium reduction with skin sodium concentration or AD severity,” they added. Noting that sodium reduction “has been shown to be a cost-effective intervention for hypertension and other cardiovascular disease outcomes,” they said that their data “support experimental studies of this approach in AD.”

They acknowledged certain limitations of the study, including the fact that a single spot urine sample was used in the UK Biobank cohort, “which only captures dietary intake of the last 24 hours and is not the best measure of usual or long-term intake of sodium.” They also noted that the findings may not be generalizable to other populations and that AD was based on self-report in the NHANES validation cohort.

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the results, said the study by Dr. Abuabara and colleagues “gives us another reason to avoid salt, showing that 1 g/day of higher salt intake increases the risk of AD in an adult population and more severe AD.”

He added that, “Now, can you say that reducing salt intake will have a therapeutic effect or clinically relevant impact? No. [That is] certainly worth exploring but at a minimum, gives some more credibility to keeping it bland.”

The study was supported by a grant from the Medical Student in Aging Research Program, the National Institute on Aging, and the National Eczema Association. Dr. Abuabara reported receiving research funding for her institution from Pfizer and Cosmetique Internacional/La Roche-Posay and consulting fees from Target RWE, Sanofi, Nektar, and Amgen. No other disclosures were reported. Dr. Friedman had no relevant disclosures.

Over a period of 5 years, the likelihood of major adverse cardiovascular events (MACE) in patients with psoriasis and dyslipidemia who were on statin therapy was 40% greater than that in non-psoriasis patients with dyslipidemia on statin therapy, even after adjusting for covariates, results from a large retrospective study showed.

“It is well-established that psoriasis is an independent risk factor for the development of MACE, with cardiometabolic risk factors being more prevalent and incident among patients with psoriasis,” the study’s first author Ana Ormaza Vera, MD, a dermatology research fellow at Eastern Virginia Medical School, Norfolk, said in an interview after the annual meeting of the Society for Investigational Dermatology, where the study was presented during a late-breaking abstract session.

Current guidelines from the joint American Academy of Dermatology/National Psoriasis Foundation and the American Academy of Cardiology/American Heart Association Task Force recommend statins, a lipid-lowering and anti-inflammatory therapy, “for patients with psoriasis who have additional risk-enhancing factors, similar to recommendations made for the general population without psoriasis,” she noted. But how the incidence of MACE differs between patients with and without psoriasis while on statin therapy “has not been explored in real-world settings,” she added.

To address this question, the researchers used real-world data from the TriNetX health research network to identify individuals aged 18-90 years with a diagnosis of both psoriasis and lipid disorders who were undergoing treatment with statins. Those with a prior history of MACE were excluded from the analysis. Patients with lipid disorders on statin therapy, but without psoriatic disease, were matched 1:1 by age, sex, race, ethnicity, common risk factors for MACE, and medications shown to reduce MACE risk. The researchers then assessed the cohorts 5 years following their first statin prescription and used the TriNetX analytics tool to calculate the odds ratio (OR) with 95% CI to evaluate the likelihood of MACE in the presence of statin therapy.

Dr. Ormaza Vera and colleagues identified 20,660 patients with psoriasis and 2,768,429 patients without psoriasis who met the criteria for analysis. After propensity score matching, each cohort included 20,660 patients with a mean age of 60 years. During the 5-year observation period, 2725 patients in the psoriasis cohort experienced MACE compared with 2203 patients in the non-psoriasis cohort (OR, 1.40; 95% CI, 1.317-1.488).

“This was an unexpected outcome that challenges the current understanding and highlights the need for further research into tailored treatments for cardiovascular risk in psoriasis patients,” Dr. Ormaza Vera told this news organization.

She acknowledged certain limitations of the study, including its retrospective design, the inherent limitations of an observational study, and the use of electronic medical record data.

Lawrence J. Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”

The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

Children with concomitant atopic dermatitis (AD) and alopecia areata (AA) who were treated with dupilumab demonstrated significant hair regrowth over a mean of nearly 68 weeks, preliminary results from a small case series showed.

“We might be opening a new avenue for a safe, long-term treatment for our children with AA,” the study’s lead investigator, Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai, New York City, said in an interview during the annual meeting of the Society for Investigative Dermatology (SID), where the results were presented during a poster session. “I think AA is likely joining the atopic march, which may allow us to adapt some treatments from the atopy world to AA.”

When the original phase 2 and phase 3 trials of dupilumab for patients with moderate to severe AD were being conducted, Dr. Guttman-Yassky, one of the investigators, recalled observing that some patients who also had patch alopecia experienced hair regrowth. “I was scratching my head because, at the time, AA was considered to be only a Th1-driven disease,” she said. “I asked myself, ‘How can this happen?’ I looked in the literature and found many publications linking atopy in general to alopecia areata. The largest of the dermatologic publications showed that eczema and atopy in general are the highest comorbidities in alopecia areata.”

Guttman_Yassky_Emma_NYC_web.jpg

“This and other findings such as IL [interleukin]-13 genetic linkage with AA and high IgE in patients with AA link AA with Th2 immune skewing, particularly in the setting of atopy,” she continued. In addition, she said, in a large biomarker study involving the scalp and blood of patients with AA, “we found increases in Th2 biomarkers that were associated with alopecia severity.”
 

Case Series of 20 Pediatric Patients

As part of a case series of children with both AD and AA, Dr. Guttman-Yassky and colleagues evaluated hair regrowth using the Severity of Alopecia Tool (SALT) in 20 pediatric patients (mean age, 10.8 years) who were being treated at Mount Sinai. They collected patient demographics, atopic history, immunoglobulin E (IgE) levels, and SALT scores at follow-up visits every 12-16 weeks for more than 72 weeks and performed Spearman correlations between clinical scores, demographics, and IgE levels.

At baseline, the mean SALT score was 54.4, the mean IgE level was 1567.7 IU/mL, and 75% of patients also had a family history of atopy. The mean follow-up was 67.6 weeks. The researchers observed a significant reduction in SALT scores at week 48 compared with baseline (a mean score of 20.4; P < .01) and continued improvement up to at least 72 weeks (P < .01 vs baseline). They also noted that patients who achieved a treatment response at week 24 had baseline IgE levels > 200 IU/mL.

In other findings, baseline IgE positively correlated with improvement in SALT scores at week 36 (P < .05), while baseline SALT scores positively correlated with disease duration (P < .01) and negatively correlated with improvement in SALT scores at weeks 24, 36, and 48 (P < .005). “The robustness of the response surprised me,” Dr. Guttman-Yassky said in the interview. “Dupilumab for AA takes time to work, but once it kicks in, it kicks in. It takes anywhere from 6 to 12 months to see hair regrowth.”

[embed:render:related:node:264415]

She acknowledged certain limitations of the analysis, including its small sample size and the fact that it was not a standardized trial. “But, based on our data and the adult data, we are very encouraged about the potential of using dupilumab for children with AA,” she said.

Mount Sinai recently announced that the National Institutes of Health awarded a $6.6 million, 5-year grant to Dr. Guttman-Yassky to further investigate dupilumab as a treatment for children with AA. She will lead a multicenter controlled trial of 76 children with alopecia affecting at least 30% of the scalp, who will be randomized 2:1 (dupilumab:placebo) for 48 weeks, followed by 48 weeks of open-label dupilumab for all participants, with 16 weeks of follow-up, for a total of 112 weeks. Participating sites include Mount Sinai, Yale University, Northwestern University, and the University of California, Irvine.

Dr. Guttman-Yassky disclosed that she is a consultant to many pharmaceutical companies, including dupilumab manufacturers Sanofi and Regeneron.

“This and other findings such as IL [interleukin]-13 genetic linkage with AA and high IgE in patients with AA link AA with Th2 immune skewing, particularly in the setting of atopy,” she continued. In addition, she said, in a large biomarker study involving the scalp and blood of patients with AA, “we found increases in Th2 biomarkers that were associated with alopecia severity.”
 

Case Series of 20 Pediatric Patients

As part of a case series of children with both AD and AA, Dr. Guttman-Yassky and colleagues evaluated hair regrowth using the Severity of Alopecia Tool (SALT) in 20 pediatric patients (mean age, 10.8 years) who were being treated at Mount Sinai. They collected patient demographics, atopic history, immunoglobulin E (IgE) levels, and SALT scores at follow-up visits every 12-16 weeks for more than 72 weeks and performed Spearman correlations between clinical scores, demographics, and IgE levels.

At baseline, the mean SALT score was 54.4, the mean IgE level was 1567.7 IU/mL, and 75% of patients also had a family history of atopy. The mean follow-up was 67.6 weeks. The researchers observed a significant reduction in SALT scores at week 48 compared with baseline (a mean score of 20.4; P < .01) and continued improvement up to at least 72 weeks (P < .01 vs baseline). They also noted that patients who achieved a treatment response at week 24 had baseline IgE levels > 200 IU/mL.

In other findings, baseline IgE positively correlated with improvement in SALT scores at week 36 (P < .05), while baseline SALT scores positively correlated with disease duration (P < .01) and negatively correlated with improvement in SALT scores at weeks 24, 36, and 48 (P < .005). “The robustness of the response surprised me,” Dr. Guttman-Yassky said in the interview. “Dupilumab for AA takes time to work, but once it kicks in, it kicks in. It takes anywhere from 6 to 12 months to see hair regrowth.”

[embed:render:related:node:264415]

She acknowledged certain limitations of the analysis, including its small sample size and the fact that it was not a standardized trial. “But, based on our data and the adult data, we are very encouraged about the potential of using dupilumab for children with AA,” she said.

Mount Sinai recently announced that the National Institutes of Health awarded a $6.6 million, 5-year grant to Dr. Guttman-Yassky to further investigate dupilumab as a treatment for children with AA. She will lead a multicenter controlled trial of 76 children with alopecia affecting at least 30% of the scalp, who will be randomized 2:1 (dupilumab:placebo) for 48 weeks, followed by 48 weeks of open-label dupilumab for all participants, with 16 weeks of follow-up, for a total of 112 weeks. Participating sites include Mount Sinai, Yale University, Northwestern University, and the University of California, Irvine.

Dr. Guttman-Yassky disclosed that she is a consultant to many pharmaceutical companies, including dupilumab manufacturers Sanofi and Regeneron.

Children with concomitant atopic dermatitis (AD) and alopecia areata (AA) who were treated with dupilumab demonstrated significant hair regrowth over a mean of nearly 68 weeks, preliminary results from a small case series showed.

“We might be opening a new avenue for a safe, long-term treatment for our children with AA,” the study’s lead investigator, Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai, New York City, said in an interview during the annual meeting of the Society for Investigative Dermatology (SID), where the results were presented during a poster session. “I think AA is likely joining the atopic march, which may allow us to adapt some treatments from the atopy world to AA.”

When the original phase 2 and phase 3 trials of dupilumab for patients with moderate to severe AD were being conducted, Dr. Guttman-Yassky, one of the investigators, recalled observing that some patients who also had patch alopecia experienced hair regrowth. “I was scratching my head because, at the time, AA was considered to be only a Th1-driven disease,” she said. “I asked myself, ‘How can this happen?’ I looked in the literature and found many publications linking atopy in general to alopecia areata. The largest of the dermatologic publications showed that eczema and atopy in general are the highest comorbidities in alopecia areata.”

Between 2011 and 2019, chronic cutaneous wounds accounted for about one third of all health care visits for cutaneous wounds, and the most common diagnoses were open wounds of the thumb without nail damage. However, fewer than 8% of chronic wounds were managed by dermatologists during this time.

Those are among key findings from an analysis of National Ambulatory Medical Care Survey (NAMCS) data between 2011 and 2019 presented as a late-breaking abstract at the annual meeting of the Society for Investigative Dermatology. “Cutaneous wounds were estimated to account for 28.1 to 96.1 billion dollars in US health care costs in 2014,” one of the study authors, Rithi Chandy, MD, MS, a research fellow at the Center for Dermatology Research at Wake Forest University School of Medicine, Winston-Salem, North Carolina, said in an interview following the meeting. “By examining national trends in patient visits and treatment, we may be able to better inform health care utilization for cutaneous wounds.”

Maternal in utero exposure to antibiotics was associated with an increased risk for infantile seborrheic dermatitis (SD) regardless of the mother’s history of SD, but this association was not as strong for childhood-onset SD.

The findings come from a large analysis of data from the United Kingdom that was presented during a late-breaking abstract session at the annual meeting of the Society for Investigative Dermatology.

SD is a common skin disease “that shares similarities with atopic dermatitis or atopic eczema as both are prevalent inflammatory skin diseases that can present with a chronic relapsing, remitting course,” the study’s corresponding author Zelma C. Chiesa Fuxench, MD, MSCE, assistant professor of dermatology at the University of Pennsylvania, Philadelphia, said in an interview. “Like atopic dermatitis, the pathophysiology of seborrheic dermatitis is thought to be complex and involves an interplay between genetics, immune dysregulation, and alterations in lipid composition and the skin microbiome, among others.”

[embed:render:related:node:267065]

“We observed that antibiotic exposure in utero was primarily associated with an increased risk of infantile SD regardless of the mother’s history of SD, but this association was not as strong for childhood-onset SD,” Dr. Chiesa Fuxench said. “This would suggest that in utero exposure to antibiotics, particularly penicillin, may have its greatest effect on the colonization of skin microbiota in the newborn period leading to the development of infantile SD. Aside from seeking to improve our understanding of the pathophysiology of SD, our findings also suggest that infantile SD and childhood-onset SD may be separate entities with different risk factors, a hypothesis that needs to be further studied.”

She acknowledged certain limitations of the analysis, including the potential for unrecorded diagnoses of SD or misclassified cases in the database. For example, AD and psoriasis “may appear clinically like SD,” she said, although they performed sensitivity analysis excluding patients with these diagnoses and found similar results. In addition, there is the possibility that not all antibiotic exposures were captured in this database, and data on antibiotic exposure may be missing, she added.

Dr. Chiesa Fuxench disclosed that she received research grants from Lilly, LEO Pharma, Regeneron, Sanofi, Tioga, Vanda, and Incyte for work related to AD and from Menlo Therapeutics and Galderma for work related to prurigo nodularis. She has served as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, AbbVie, Incyte Corporation, and Pfizer and received honoraria for CME work in AD sponsored by education grants from Regeneron/Sanofi and Pfizer and from Beiersdorf for work related to skin cancer and sun protection.

Clinicians should incorporate at least one of three validated instruments to measure signs of atopic dermatitis (AD) in their clinical practice, the authors of a new consensus statement recommended.

These include the Eczema Area and Severity Index (EASI), the Validated Investigator Global Assessment for AD (vIGAAD), and the Investigator’s Global Assessment (IGA) multiplied by or measured concurrently with a body surface area (BSA) assessment.

[embed:render:related:node:267193]

The recommendations are part of a consensus statement based on an updated systematic review conducted by the Harmonizing Outcome Measures for Eczema Clinical Practice (HOME-CP) initiative, whose goal is to identify validated, feasible outcome instruments designed to measure AD in the clinical setting. In the statement, which was published in JAMA Dermatology on May 22, 2024, corresponding author Eric L. Simpson, MD, MCR, professor of dermatology at Oregon Health & Science University, Portland, and coauthors described HOME-CP as “a ‘pick-and-choose’ list of valid and feasible OMIs [outcome measure instruments] that can be incorporated into the practice setting depending on the particular need of that clinic or health system.”

For the effort, the authors implemented a mixed methods design and incorporated systematic reviews and qualitative consensus methods modeled after the HOME core outcome set initiative, which developed a set of consensus-based core outcome sets for clinical trials and clinical practice. In October of 2022, a daylong in-person consensus exercise was held in Montreal, Canada, where attendees met to reach consensus on recommended instruments to measure AD clinical signs in clinical practice, based on an updated systematic review evaluating the validity of clinical signs instruments.

The review included 22 studies describing 16 instruments that assessed AD clinical signs and an additional 12 variants of instruments. The meeting was attended by 34 individuals from 13 countries, including patient and patient advocate research partners, health care professionals, researchers, methodologists, and industry representatives. Consensus was defined as less than 30% disagreement.

Following their daylong consensus exercise, the stakeholders reached consensus on recommendations to use the EASI, the vIGAAD, and an IGA multiplied or measured alongside a BSA measurement to measure the domain of clinical signs of AD in the clinical practice setting. “The use of multiple IGAs, most with insufficient validation, and the diverse methods used to assess BSA prevented participants from making specific recommendations for the exact IGA/BSA instrument,” the authors wrote. “We recommend that clinicians include at least one of the recommended instruments in their clinical practices and in documentation.” 

They explained that the ideal method of measuring BSA was difficult to assess “because multiple techniques exist for its measurement, including regional percentages, the Rule of Nines, or the handprint method. Most studies did not report which method was performed, and to our knowledge, no studies have been performed in patients with AD that have formally compared them.”

During the consensus exercise, the authors noted, several clinicians “expressed concern whether the EASI was feasible for universal use in clinical practice given its complexity, long completion time, and documentation/calculation requirements.” But clinicians who commonly perform the EASI in clinical practice said that the time it takes to complete this measure “has dropped substantially and now is not a considerable burden,” they wrote, adding that, “studies have shown that with trained investigators, EASI completion times can be as low as nearly 2 minutes.”

The authors acknowledged certain limitations of their recommendations, including the lack of input from primary care clinicians. “It is unknown whether ClinROMs [clinician-reported outcome measures] for AD clinical signs are used in the primary care setting, especially given the large amount of conditions that are managed simultaneously and the ever-increasing number of primary care documentation requirements,” they wrote.

Robert Sidbury, MD, MPH, chief of the division of dermatology at Seattle Children’s Hospital, who was asked to comment on the consensus statement, said that with the advent of new, improved, and more expensive medications for AD, “it is ever more important that [the clinical] assessment is reliable and reproducible.”

Insurers “are understandably less willing to rubber-stamp approval of more expensive medications without a reliable standard by which to justify such decisions,” he added. “This is even more important in a disease state like atopic dermatitis that lacks a reliable biomarker. Therefore, one or several practical, reliable, validated severity metrics will help standardize and improve AD care.”

Dr. Sidbury, who cochaired the 2023 American Academy of Dermatology guidelines of care for the management of AD in adults with phototherapy and systemic therapies, added that the instruments evaluated in the review “can be challenging for anyone,” not just primary care providers. “The EASI isn’t that easy, and while there is a learning curve and it ultimately does, like anything, become more efficient in the gathering, it is unclear if non-AD researchers will be willing to invest the time” to routinely use it, he said.

Dr. Simpson and several coauthors reported receiving grants and personal fees from multiple pharmaceutical companies. Dr. Sidbury reported that he serves as an investigator for Regeneron, Galderma, UCB, Castle, and Pfizer; is a consultant for LEO, Lilly, Arcutis, Dermavant, and Pierre Fabre; and a speaker for Beiersdorf.

Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania in Philadelphia, presented results from the LITE study, a trial that tested the hypothesis that narrowband ultraviolet B phototherapy of psoriasis at home is noninferior to office treatment, based on outcomes that matter to patients, clinicians, and payers. While smaller studies have drawn similar conclusions, LITE was the largest trial of its kind to show what many dermatologists have suspected for years: Home phototherapy can be an effective first-line treatment for patients with moderate to severe psoriasis.

The co-primary outcomes in the LITE study were a Physician’s Global Assessment (PGA) score of 0/1 (clear, almost clear) and a Dermatology Life Quality Index (DLQI) score of 5 or less (small, no effect on health-related quality of life).

Dr. Gelfand and colleagues at 42 sites in the United States enrolled 783 patients aged 12 years and older who had plaque or guttate psoriasis and were candidates for phototherapy at home or in an office setting. Following 12 weeks of treatment, 25.6% of patients in the office-based phototherapy group achieved a PGA score of 0/1 compared with 32.8% of patients in the home-based phototherapy group (P > .0001 for noninferiority, non-response imputation for missing data). Similarly, 33.6% of patients in the office-based phototherapy group achieved a DLQI score of 5 or less compared with 52.4% of patients in the home-based phototherapy group (P > .0001 for noninferiority, non-response imputation for missing data).

A Safe and Effective Option

“I think that it’s important for physicians, insurance companies, and patients with psoriasis to understand that this is a very safe and effective form of therapy,” Craig A. Elmets, MD, professor of dermatology at The University of Alabama at Birmingham, said in an interview. “For people who are not interested in systemic medications or who have contraindications to systemic medications, phototherapy would be ideal,” added Dr. Elmets, first author of the joint AAD–National Psoriasis Foundation (NPF) guidelines for the management and treatment of psoriasis with phototherapy, published in 2019.

Factors beyond efficacy support the role of home phototherapy, Dr. Gelfand said, including the fact that it costs 10-100 times less than biologics for psoriasis and that office-based phototherapy is not available in 90% of counties in the United States. However, insurance coverage of home phototherapy “is highly variable because until the LITE study, there was no large-scale US data to support its use,” he told this news organization.

“Also, insurance companies are broken up into two parts: Durable medical goods and the medical side such as pharmacy costs, and they are siloed. The durable medical goods side views phototherapy as expensive, while the pharmacy side views it as dirt cheap. This is part of the problem with our health system. A lot of things are siloed and don’t make any sense,” said Dr. Gelfand, director of the Psoriasis and Phototherapy Treatment Center at the University of Pennsylvania. By working with the NPF and payers, he added, “we’re hoping ... to transform the way insurance companies think about covering home phototherapy.”

In the meantime, he and Dr. Elmets shared practical ways to optimize access to home phototherapy for psoriasis patients:

Have the discussion. Patients “rarely bring this up as an option,” Dr. Elmets said, so the onus is on clinicians to talk about it. In his view, the ideal candidate “is averse to using systemic agents but whose disease is beyond the point where topical medicines alone will work. One of the advantages of phototherapy is that it doesn’t have immunosuppressive effects.”

towrirotushajohepraliphofrejistophospaposufruswupauoclihikicapudasleprunujawrereseshochucheluchuradrothibriclahesowrastarojasak

Clinicians and patients can learn about the efficacy and safety of phototherapy for psoriasis, including home-based options, on the NPF’s web site and by reading the 2019 joint AAD-NPF guidelines.

Shared decision-making is key. “When a patient comes in, I’ll discuss what their treatment options are and [we] will decide upon a course of action based on their unique needs and preferences [and] if it’s medically appropriate, meaning they have the type of psoriasis likely to respond to phototherapy,” Dr. Gelfand said. A patient with psoriasis mainly on the fingernails or genitals “is not a good candidate for phototherapy. If it’s on the trunk or extremities, that patient would be a good candidate.”

Home phototherapy candidates also must be willing and able to operate a machine and have dedicated space in their dwelling for it (most units are about the size of a door). Patients also have to be reliable, follow directions, and come back in person for follow-up appointments “so we can assess their response to treatment and fine-tune things as necessary and make sure they’re not developing any skin damage,” Dr. Gelfand said.

Educate yourself about existing options. Home phototherapy units from manufacturers such as Daavlin, National Biological Corporation, and SolRx range between $1200 and $6000 in cost, Dr. Gelfand said. He and his colleagues used the Daavlin 7 series in the LITE study. That unit features an integrated dosimetry system that delivers the correct dose of energy based on parameters that the prescribing clinician recommends. Settings are based on the patient’s skin type and how much the prescriber wants to increase the dose for each treatment. “The machine does the rest,” he said. “It knows what dose to give, so they get the same dosing as they would in an office situation.”

Smaller home-based phototherapy units designed to treat the hands and feet are available. So are handheld units to treat the scalp. “These can be a nice option for patients who have a few spots, but if the disease is moderate to severe, then it’s going to be pretty laborious to [use them],” Dr. Elmets said.

Remember that phototherapy is not a cure-all. According to the joint AAD-NPF guidelines, most phototherapy regimens require treatments two to three times per week for 10-14 weeks. Once patients achieve their home phototherapy treatment goal, Dr. Elmets often recommends treatments one to two times per week for maintenance.

“Patients with psoriasis have a lifetime condition,” he noted. “There are certainly cases where people have gone on phototherapy, cleared, and then stopped for a period of time. If they flare up, they can always go back to phototherapy. Usually, people who are on phototherapy use some type of topical agents to touch up areas that are resistant.”

Expect pushback from insurers on coverage. While Medicare and some integrated health plans cover home phototherapy, expect to spend time writing letters or placing phone calls to insurance companies to convince them why they should cover home phototherapy for candidate psoriasis patients. “Usually there’s a lot of letter writing and a long delay in getting approval,” Dr. Elmets said.

Dr. Elmets and Dr. Gelfand reported no relevant financial relationships. The LITE study was funded by the Patient-Centered Outcomes Research Institute. Research partners included the National Psoriasis Foundation and Daavlin, which provided the home phototherapy machines and covered the cost of shipping the devices.

Local injection of tranexamic acid (TXA) effectively reduced the risk for clinically significant bleeding following Mohs micrographic surgery (MMS), results from a single-center cohort study showed.

“Though Mohs micrographic surgery is associated with low bleeding complication rates, around 1% of patients in the literature report postoperative bleeding,” corresponding author Abigail H. Waldman, MD, director of the Mohs and Dermatologic Surgery Center, at Brigham and Women’s Hospital, Boston, and colleagues wrote in the study, which was published online in the Journal of the American Academy of Dermatology. “Intravenous tranexamic acid has been used across surgical specialties to reduce perioperative blood loss. Prior studies have shown topical TXA, an antifibrinolytic agent, following MMS may be effective in reducing postoperative bleeding complications, but there are no large cohort studies on injectable TXA utilization in all patients undergoing MMS.”

To improve the understanding of this intervention, the researchers examined the impact of off-label, locally injected TXA on postoperative bleeding outcomes following MMS conducted at Brigham and Women’s Hospital. They evaluated two cohorts: 1843 patients who underwent MMS from January 1, 2019, to December 31, 2019 (the pre-TXA cohort), and 2101 patients who underwent MMS from July 1, 2022, to June 30, 2023 (the TXA cohort), and extracted data, including patient and tumor characteristics, MMS procedure details, antithrombotic medication use, systemic conditions that predispose to bleeding, encounters reporting postoperative bleeding, and interventions required for postoperative bleeding, from electronic medical records. Patients reconstructed by a non-MMS surgeon were excluded from the analysis.

Overall, 2509 cases among 1843 patients and 2818 cases among 2101 were included in the pre-TXA and TXA cohorts, respectively. The researchers found that local subcutaneous injection of TXA reduced the risk for postoperative phone calls or visits for bleeding by 25% (RR [risk ratio], 0.75; 0.57-0.99) and risk for bleeding necessitating a medical visit by 51% (RR, 0.49; 0.32-0.77).

The use of preoperative TXA in several subgroups of patients also was also associated with a reduction in visits for bleeding, including those using alcohol (52% reduction; RR, 0.47; 0.26-0.85), cigarettes (57% reduction; RR, 0.43; 0.23-0.82), oral anticoagulants (61% reduction; RR, 0.39; 0.20-0.77), or antiplatelets (60% reduction; RR, 0.40; 0.20-0.79). The use of TXA was also associated with reduced visits for bleeding in tumors of the head and neck (RR, 0.45; 0.26-0.77) and tumors with a preoperative diameter > 2 cm (RR, 0.37; 0.15-0.90).

[embed:render:related:node:254963]

Impact of Surgical Repair Type

In other findings, the type of surgical repair was a potential confounder, the authors reported. Grafts and flaps were associated with an increased risk for bleeding across both cohorts (RR, 2.36 [1.5-3.6] and 1.7 [1.1-2.6], respectively) and together comprised 15% of all procedures in the pre-TXA cohort compared with 11.1% in TXA cohort. Two patients in the TXA cohort (0.11%) developed deep vein thrombosis (DVT) 10- and 20-days postoperation, a rate that the authors said is comparable to that of the general population. The two patients had risk factors for hypercoagulability, including advanced cancer and recurrent DVT.

“Overall, local injection of TXA was an effective method for reducing the risk of clinically significant bleeding following MMS,” the researchers concluded. “Perioperative TXA may help to limit the risk of bleeding overall, as well as in populations predisposed to bleeding.” Adverse events with TXA use were rare “and delayed beyond the activity of TXA, indicating a low likelihood of being due to TXA,” they wrote.

“Dermatologists performing MMS may consider incorporating local TXA injection into their regular practice,” they noted, adding that “legal counsel on adverse effects in the setting of off-label pharmaceutical usage may be advised.”

In an interview, Patricia M. Richey, MD, director of Mohs surgery at Boston Medical Center, who was asked to comment on the study, said that postoperative bleeding is one of the most commonly encountered Mohs surgery complications. “Because of increased clinic visits and phone calls, it can also often result in decreased patient satisfaction,” she said.

“This study is particularly notable in that we see that local subcutaneous TXA injection decreased visits for bleeding even in those using oral anticoagulants, antiplatelets, alcohol, and cigarettes. Dermatologic surgery has a very low complication rate, even in patients on anticoagulant and antiplatelet medications, but this study shows that TXA is a fantastic option for Mohs surgeons and patients.”

Neither the study authors nor Dr. Richey reported having financial disclosures.

They evaluated two cohorts: 1843 patients who underwent MMS from January 1, 2019, to December 31, 2019 (the pre-TXA cohort), and 2101 patients who underwent MMS from July 1, 2022, to June 30, 2023 (the TXA cohort), and extracted data, including patient and tumor characteristics, MMS procedure details, antithrombotic medication use, systemic conditions that predispose to bleeding, encounters reporting postoperative bleeding, and interventions required for postoperative bleeding, from electronic medical records. Patients reconstructed by a non-MMS surgeon were excluded from the analysis.

Overall, 2509 cases among 1843 patients and 2818 cases among 2101 were included in the pre-TXA and TXA cohorts, respectively. The researchers found that local subcutaneous injection of TXA reduced the risk for postoperative phone calls or visits for bleeding by 25% (RR [risk ratio], 0.75; 0.57-0.99) and risk for bleeding necessitating a medical visit by 51% (RR, 0.49; 0.32-0.77).

The use of preoperative TXA in several subgroups of patients also was also associated with a reduction in visits for bleeding, including those using alcohol (52% reduction; RR, 0.47; 0.26-0.85), cigarettes (57% reduction; RR, 0.43; 0.23-0.82), oral anticoagulants (61% reduction; RR, 0.39; 0.20-0.77), or antiplatelets (60% reduction; RR, 0.40; 0.20-0.79). The use of TXA was also associated with reduced visits for bleeding in tumors of the head and neck (RR, 0.45; 0.26-0.77) and tumors with a preoperative diameter > 2 cm (RR, 0.37; 0.15-0.90).

Impact of Surgical Repair Type

In other findings, the type of surgical repair was a potential confounder, the authors reported. Grafts and flaps were associated with an increased risk for bleeding across both cohorts (RR, 2.36 [1.5-3.6] and 1.7 [1.1-2.6], respectively) and together comprised 15% of all procedures in the pre-TXA cohort compared with 11.1% in TXA cohort. Two patients in the TXA cohort (0.11%) developed deep vein thrombosis (DVT) 10- and 20-days postoperation, a rate that the authors said is comparable to that of the general population. The two patients had risk factors for hypercoagulability, including advanced cancer and recurrent DVT.

“Overall, local injection of TXA was an effective method for reducing the risk of clinically significant bleeding following MMS,” the researchers concluded. “Perioperative TXA may help to limit the risk of bleeding overall, as well as in populations predisposed to bleeding.” Adverse events with TXA use were rare “and delayed beyond the activity of TXA, indicating a low likelihood of being due to TXA,” they wrote.

“Dermatologists performing MMS may consider incorporating local TXA injection into their regular practice,” they noted, adding that “legal counsel on adverse effects in the setting of off-label pharmaceutical usage may be advised.”

In an interview, Patricia M. Richey, MD, director of Mohs surgery at Boston Medical Center, who was asked to comment on the study, said that postoperative bleeding is one of the most commonly encountered Mohs surgery complications. “Because of increased clinic visits and phone calls, it can also often result in decreased patient satisfaction,” she said.

“This study is particularly notable in that we see that local subcutaneous TXA injection decreased visits for bleeding even in those using oral anticoagulants, antiplatelets, alcohol, and cigarettes. Dermatologic surgery has a very low complication rate, even in patients on anticoagulant and antiplatelet medications, but this study shows that TXA is a fantastic option for Mohs surgeons and patients.”

Neither the study authors nor Dr. Richey reported having financial disclosures.

Treatment options for individuals with early-stage hidradenitis suppurativa (HS) vary depending on patient preference and how clinicians define “early” HS. This can be challenging because to date, no Food and Drug Administration–approved treatments exist for early-stage HS and only two biologics exist for moderate to severe disease.

“For someone with occasional nodules and abscesses, we often use antibiotics and topical antiseptics,” Christopher Sayed, MD, a dermatologist at the HS and Follicular Disorders Clinic at the University of North Carolina, Chapel Hill, told this news organization. “We may use these daily for weeks or months or just provide them to use for 1-2 weeks at a time for intermittent flares if a patient doesn’t want to take a pill every day,” he said. “For women, hormonal options like oral contraceptive pills and spironolactone can be a great option” if they don’t mind taking a daily pill.

Topical options that Jennifer L. Hsiao, MD, reaches for in her role as director of the HS clinic at the University of Southern California, Los Angeles, include chlorhexidine wash, topical clindamycin, and topical resorcinol. Systemic medications include oral antibiotics such as doxycycline or clindamycin, while hormonal options include oral contraceptives and/or spironolactone for women and finasteride for men.

Metformin Among Options to Consider

According to Dr. Hsiao, other treatment options to consider trying in patients with mild HS include metformin, “especially in patients who also have prediabetes, PCOS, or obesity;” isotretinoin if the patient has concomitant severe acne; botulinum toxin injections; apremilast or topical roflumilast, and antihyperhidrosis medications such as prescription aluminum chloride topicals, glycopyrronium wipes, and glycopyrrolate.

Recommending lifestyle modifications such as smoking cessation and weight loss for patients diagnosed with early-stage HS is “challenging,” Dr. Sayed said, “because the evidence on different triggers and lifestyle modifications isn’t very strong. There can also be a lot of stigmas around weight and smoking in HS, and it can alienate patients to go straight to these topics in the first visit.”

Early Data on Ruxolitinib Cream Promising

At the 2024 annual meeting of the American Academy of Dermatology, researchers reported on the results of a phase 2 study, which found that topical 1.5% ruxolitinib, a Janus kinase (JAK) inhibitor (currently FDA-approved for atopic dermatitis) was effective in reducing abscess and inflammatory nodule count in patients with mild HS. “There is a major need for this kind of option, and the early results are promising,” said Dr. Sayed, who was not involved with the study. “It’s very difficult to get this covered for patients currently since it is off label for HS. We’ve gotten it for a few patients, and one has really liked it, but it’s unclear how consistent the others were with their use, and their level of improvement was not clear to me.”

For mild HS, he added, “the most important area in which we’ve seen growing evidence is around hair removal lasers such as Nd:YAG and alexandrite lasers. Improving access for patients is a major priority in the coming years.”

[embed:render:related:node:268380]

According to Dr. Hsiao, other approaches being studied for treating mild HS include a topical aryl hydrocarbon receptor agonist known as AT193, and oral medications, such as phosphodiesterase-4 inhibitors. Laser therapies are also being studied, “such as fractional ablative CO₂ laser therapy combined with topical triamcinolone,” she said. “However, the majority of ongoing HS trials are for moderate to severe disease, so there is certainly a need for more investigation into mild HS treatment approaches.”

Dr. Sayed disclosed that he is secretary of the HS Foundation and a member of the European HS Foundation. He has served as a consultant for AbbVie, Alumis, AstraZeneca, Incyte, InflaRx, Novartis, Sanofi, Sonoma Biotherapeutics, and UCB; as a speaker for AbbVie, Novartis, and UCB; and as an investigator for Chemocentryx, Incyte, InflaRx, Novartis, and UCB. Dr. Hsiao disclosed that she is a member of the board of directors for the HS Foundation and has served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie, Novartis, Sanofi Regeneron, and UCB; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

Based on his experience caring for patients with hidradenitis suppurativa (HS), dermatologist Christopher Sayed, MD, said that an exhaustive battery of tests is usually not required to diagnose early-stage HS, which can be mistaken for other conditions, such as an infection, folliculitis, and acne.

According to 2019 guidelines from the United States and Canadian hidradenitis suppurativa foundations, the diagnostic criteria for HS in general are the presence of typical lesions such as abscesses, nodules, and tunnels in classic locations such as underarms, groins, and buttocks that recur over the course of at least 6 months. “There is no need for additional testing or imaging to make the diagnosis,” said Dr. Sayed, co-chair of the 2019 guidelines work group, who sees patients at the HS and Follicular Disorders Clinic at the University of North Carolina, Chapel Hill. “In many ways, the diagnosis should be very simple since the presentation is classic in most cases, though it can be confusing in the first 6 months or so.”

Persistence, Recurrence Major Clues

Prior to being diagnosed with Hurley stage I HS — characterized by recurrent nodules and abscesses with minimal scars, according to the guidelines — most people figure they’ve been getting recurrent Staphylococcus aureus infections or are having trouble with ingrown hairs from shaving, he continued. They may also say they get “boils” without an understanding of what has been causing them.

“Early HS can mimic an intense folliculitis or furuncles that can sometimes be caused by Staphylococcus infections, but the history of persistence or recurrence for months, despite treatment that should cover something like a Staph infection is a major clue,” Dr. Sayed said. “Thanks to improved resources on the internet, more patients, compared to several years ago, come in asking about HS after they’ve done their own research. As public awareness improves, hopefully this trend will grow, and patients will be diagnosed and treated earlier.” Family history is also a strong predictor of HS, since about half of patients have first-degree relatives who have a history of HS, he noted.

The ‘2-2-6 Rule’

When she sees a patient who might have HS, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, follows the “2-2-6 rule,” which involves asking patients if they have had 2 episodes of 2 or more abscesses in 6 months. “If the patient answers yes, there’s a high likelihood that person has HS,” she said.

Hurley stage I HS is defined as nodules and abscesses without sinus tracts (tunnels) or scarring. But in Dr. Hsiao’s opinion, the Hurley staging system “is not the best way to characterize disease activity” because some patients meet criteria for Hurley stage I disease, meaning they do not have any scars or sinus tracts/tunnels, “but they have high disease activity with several inflammatory nodules and large painful abscesses that are limiting their quality of life and ability to function.”

• Do you have a primary care provider (PCP)? PCPs are important care partners for patients with HS doctor to help screen for the comorbidities associated with the condition.
• What seems to make your HS worse? This can help identify potential triggers to avoid.
• What other medical conditions do you have?
• How would you describe the impact HS has on your quality of life?
• For women: Does your HS get worse around your period? “This can help to identify a potential hormonal trigger,” she said. “If the patient answers ‘yes,’ I would strongly consider a combined oral contraceptive pill and/or spironolactone as part of the patient’s treatment regimen.”

‘Window of Opportunity’ to Intervene

According to Dr. Hsiao, there has been a paradigm shift in the approach to HS management that emphasizes a “window of opportunity,” where earlier initiation of appropriate long-term immunomodulator therapy is recommended to try to mitigate disease progression. The development of tunnels and scars is a telltale sign that permanent tissue destruction is occurring, and the patient’s HS is no longer mild.

Ideally, a conversation about adalimumab, a tumor necrosis factor inhibitor, and secukinumab, an interleukin-17A antagonist (the two currently Food and Drug Administration–approved medications for HS, for moderate to severe disease/Hurley stage II/III) will have already been started with patients prior to development of a high tunnel or scar burden, signs of later-stage disease.

“Medications like this have the potential to slow and prevent that progression and reduce the surgical burden patients face over time, which is a major priority,” Dr. Sayed said. He noted that while comfort level with managing HS can vary among clinicians, “I’d encourage dermatologists to stay engaged with these patients because our training in the medical and surgical management of complex diseases like this is unmatched among other specialties,” he said. “Education of colleagues in other specialties should also be a big priority, especially for those in urgent care, emergency medicine, surgery, and ob.gyn. who often encounter these patients and may be less familiar” with HS.

Besides the North American clinical management guidelines for HS, which are expected to be updated in the next 18-24 months, as well as comorbidity screening recommendations for HS published in 2022, another resource Dr. Sayed and Dr. Hsiao recommend is the HS Foundation website, which features a link to Continuing Medical Education video lectures. The foundation also hosts an annual Symposium on HS Advances. This year’s event is scheduled in November in Austin, Texas.

The ‘2-2-6 Rule’

When she sees a patient who might have HS, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, follows the “2-2-6 rule,” which involves asking patients if they have had 2 episodes of 2 or more abscesses in 6 months. “If the patient answers yes, there’s a high likelihood that person has HS,” she said.

Hurley stage I HS is defined as nodules and abscesses without sinus tracts (tunnels) or scarring. But in Dr. Hsiao’s opinion, the Hurley staging system “is not the best way to characterize disease activity” because some patients meet criteria for Hurley stage I disease, meaning they do not have any scars or sinus tracts/tunnels, “but they have high disease activity with several inflammatory nodules and large painful abscesses that are limiting their quality of life and ability to function.”

• Do you have a primary care provider (PCP)? PCPs are important care partners for patients with HS doctor to help screen for the comorbidities associated with the condition.
• What seems to make your HS worse? This can help identify potential triggers to avoid.
• What other medical conditions do you have?
• How would you describe the impact HS has on your quality of life?
• For women: Does your HS get worse around your period? “This can help to identify a potential hormonal trigger,” she said. “If the patient answers ‘yes,’ I would strongly consider a combined oral contraceptive pill and/or spironolactone as part of the patient’s treatment regimen.”

‘Window of Opportunity’ to Intervene

According to Dr. Hsiao, there has been a paradigm shift in the approach to HS management that emphasizes a “window of opportunity,” where earlier initiation of appropriate long-term immunomodulator therapy is recommended to try to mitigate disease progression. The development of tunnels and scars is a telltale sign that permanent tissue destruction is occurring, and the patient’s HS is no longer mild.

Ideally, a conversation about adalimumab, a tumor necrosis factor inhibitor, and secukinumab, an interleukin-17A antagonist (the two currently Food and Drug Administration–approved medications for HS, for moderate to severe disease/Hurley stage II/III) will have already been started with patients prior to development of a high tunnel or scar burden, signs of later-stage disease.

“Medications like this have the potential to slow and prevent that progression and reduce the surgical burden patients face over time, which is a major priority,” Dr. Sayed said. He noted that while comfort level with managing HS can vary among clinicians, “I’d encourage dermatologists to stay engaged with these patients because our training in the medical and surgical management of complex diseases like this is unmatched among other specialties,” he said. “Education of colleagues in other specialties should also be a big priority, especially for those in urgent care, emergency medicine, surgery, and ob.gyn. who often encounter these patients and may be less familiar” with HS.

Besides the North American clinical management guidelines for HS, which are expected to be updated in the next 18-24 months, as well as comorbidity screening recommendations for HS published in 2022, another resource Dr. Sayed and Dr. Hsiao recommend is the HS Foundation website, which features a link to Continuing Medical Education video lectures. The foundation also hosts an annual Symposium on HS Advances. This year’s event is scheduled in November in Austin, Texas.

Dr. Sayed disclosed that he is secretary of the HS Foundation and a member of the European HS Foundation. He has served as a consultant for AbbVie, Alumis, AstraZeneca, Incyte, InflaRx, Novartis, Sanofi, Sonoma Biotherapeutics, and UCB; as a speaker for AbbVie, Novartis, and UCB; and as an investigator for Chemocentryx, Incyte, InflaRx, Novartis, and UCB. Dr. Hsiao disclosed that she is a member of the board of directors for the HS Foundation and has served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie, Novartis, Sanofi Regeneron, and UCB; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.
