Lebrikizumab, an investigational interleukin-13 inhibitor, showed significant efficacy compared with placebo across racial and ethnic subgroups in patients with moderate-to-severe atopic dermatitis.

The finding comes from an analysis of the 16-week induction periods of the phase 3 ADvocate1 and ADvocate2 trials, which Raj Chovatiya, MD, PhD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. The efficacy of lebrikizumab monotherapy to treat moderate-to-severe AD has been established in phase 3 studies, “but disease characteristic and efficacy outcomes may vary among racial and ethnic subgroups,” said Dr. Chovatiya, assistant professor in the department of dermatology at Northwestern University, Chicago. “The goal of the current study is to report the week 16 efficacy of lebrikizumab-treated patients in racial and ethnic subgroups from ADvocate1 and ADvocate2.”

Dr. Chovatiya

Key eligibility criteria for both trials included adults or adolescents with a diagnosis of AD as defined by the American Academy of Dermatology Consensus Criteria, for at least 1 year prior to screening. They had moderate-to-severe AD, were candidates for systemic therapy, and were dupilumab- and tralokinumab-naive. Outcomes of interest were the Investigator’s Global Assessment 0 or 1, with at least a 2-point improvement; and the proportions of patients who achieved Eczema Area and Severity Index (EASI75) and EASI90 responses, and an improvement of 4 points or more on the Pruritus Numeric Rating Scale (NRS).

For statistical analysis, the researchers pooled data from Advocate1 and Advocate2 and applied imputation methodology to the 16-week induction period. Subsequent data from patients who received topical or systemic rescue medication or discontinued treatment due to lack of efficacy were imputed as nonresponders. Subsequent data from patients who discontinued treatment for other reasons were set to missing, and the researchers handled missing data with multiple imputation. They used logistic regression to test the interaction between the treatment and subgroup and the Cochran-Mantel-Haenszel method to evaluate the treatment effect within each subgroup after adjusting for stratification factors.

Dr. Chovatiya reported findings from the 851 study participants in the combined studies. Of these, 542 were White, 192 were Asian, 84 were Black, and 33 were from other racial subgroups. By ethnic subgroup, 748 were not Hispanic or Latino, 91 were Hispanic or Latino, and ethnicity was unknown or not reported for 12 subjects. At baseline, the mean body mass index was slightly higher among Blacks (30.4 kg/m²) and Hispanics (29.4 kg/m²) compared with other racial and ethnic groups, “which reflects general epidemiologic data among these groups in the United States,” Dr. Chovatiya said. “You can also see a difference in the balance of IGA scores — they were a little bit more severe in the Black or African American and Hispanic groups as well.” The researchers also observed differences in the baseline EASI score across some of these groups, particularly in the Asian individuals, who had higher EASI scores. Prior use of systemic therapy was lower in the Black and “other” subgroups, compared with other racial subgroups.

At week 16, key efficacy endpoints were generally similar between the different racial subgroups. Specifically, 25.1% of Asians in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 4.1% of those in the placebo group (P < .001), while 33.2% of Blacks in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 13.2% of those in the placebo group (no P value was established because this subgroup represented less than 10% of the entire study population). In addition, 43.3% of Whites in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 14.1% of those in the placebo group (P < .001).

In other findings, 45.5% of Asians in the lebrikizumab treatment group achieved an EASI75, compared with 8.5% of those in the placebo group (P < .001), while 51.7% of Blacks in the lebrikizumab treatment group achieved an EASI75, compared with 18.8% of those in the placebo group. Among whites in the lebrikizumab treatment group, 59.7% of achieved an EASI75, compared with 20.4% of those in the placebo group (P < .001).

Dr. Chovatiya said that 26.5% of Asians in the lebrikizumab treatment group achieved an EASI90, compared with 4.3% of those in the placebo group (P < .001), while 26.9% of Blacks in the lebrikizumab treatment group achieved an EASI90, compared with 13.2% of those in the placebo group. In addition, 38.3% of Whites in the lebrikizumab treatment group achieved an EASI90, compared with 10.9% of those in the placebo group (P < .001).

Finally, 36.4% of Asians in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 5.7% of those in the placebo group (P <. 001), while 41.7% of Blacks in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 17.4% of those in the placebo group. In addition, 45.9% of Whites in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 14.8% of those in the placebo group (P < .001). Statistical analyses of efficacy endpoints conducted by ethnic group yielded similar results.

Dr. Chovatiya acknowledged certain limitations of the study, including the fact that differences in baseline demographics and disease characteristics limit direct comparison across racial and ethnic subgroups. “Due to the relatively small sample size of some racial and ethnic subgroups and the post hoc nature of this analysis, additional studies are needed to verify these results,” he concluded. But for now, he said, the data available indicate that “lebrikizumab is effective across racial and ethnic subgroups for the treatment of moderate-to-severe AD after 16 weeks of monotherapy treatment.”

A study investigating the effectiveness of a pilot program to educate barbers about pseudofolliculitis barbae (PFB) found that the barbers significantly improved their knowledge about the causes, prevention, and treatment of the condition after the educational intervention.

The results were published in a research letter in JAMA Dermatology. “Educating barbers on dermatologic conditions that disproportionately affect Black males and establishing referral services between barbers and dermatologists could serve as plausible interventions,” the authors wrote.

PFB — or “razor bumps” in layman’s terms — is a chronic, inflammatory follicular disorder, which can occur in any racial group, but primarily affects Black men, noted the corresponding author of the study, Xavier Rice, MD, a dermatology resident at Washington University in Saint Louis, Missouri. PFB manifests as bumps and pustules or nodules along the beard line and are painful, he said in an interview. “They tend to leave scars once they resolve,” and impair the ability to shave, he noted.

In some communities, Black men may see their barbers more often than primary care doctors or dermatologists, “so if you equip the barbers with the knowledge to recognize the disease, make recommendations on how to prevent and to treat, and also form some allyship with barbers and dermatologists, then we can get referrals for people, especially the ones with severe disease,” he said. A lot of the barbers in the study said that “they didn’t receive much education on how to properly address it [PFB] and they had a lot of miseducation about what actually caused it,” added Dr. Rice, who was a medical student at the University of Texas Medical Branch, Galveston, when the study was conducted.

Study involved 40 barbers

For the study, Dr. Rice and his coauthors surveyed 40 barbers in the Houston, Texas, area; 39 were Black and one was Hispanic; 75% were men and 25% were women. Most (90%) said that at least 60% of their clients were Black. Between January and April 2022, the barbers received questionnaires before and after participating in a session that involved a review of a comprehensive educational brochure with information on the recognition, cause, prevention, and treatment of PFB, which they then kept for reference and to provide to clients as needed. “Common myths and nuanced home remedies from barber experience were also addressed,” the authors wrote.

No more than 2 weeks after the information session, each barber completed a posttest questionnaire.

Based on their responses to pretest questions, 39 of the 40 barbers understood that Black men were the group most impacted by PFB and that a person with severe PFB should see a physician. In the pretest survey, 12 barbers (30%) correctly recognized a photo of PFB, which increased to 39 (97.5%) in the posttest survey. In the pretest survey, two barbers (5%) identified laser hair removal as the most effective treatment for PFB, compared with 37 (92.5%) in the posttest survey.

Overall, the mean percentage of correct scores out of 20 questions was 54.8% in the pretest survey, increasing to 91% in the posttest survey (P <.001).

Limitations of the studies included heterogeneity in the survey response options that potentially could have introduced bias, the authors wrote. Another was that since there is a lack of evidence for ideal treatment strategies for PFB, there may have been some uncertainty among the correct answers for the survey that might have contributed to variability in responses. “Further research and implementation of these interventions are needed in efforts to improve health outcomes,” they added.

“Barbers can serve as allies in referral services,” Dr. Rice said in the interview. “They can be the first line for a number of diseases that are related to hair.”

Part of his role as a dermatologist, he added, includes going into a community with “boots on the ground” and talking to people who will see these patients “because access to care, presentation to big hospital systems can be challenging.”

Dr. Rice and the other study authors had no not report any financial disclosures.

The increased risk of vitiligo found in recipients of stem cell and solid organ transplants, especially those who develop graft-versus-host disease (GVHD), requires careful monitoring, according to authors of a study published online in JAMA Dermatology December 13.

In the cohort study, the greatest risk occurred with hematopoietic stem cell transplants (HSCTs) and in cases involving GVHD. Kidney and liver transplants carried slight increases in risk.

“The findings suggest that early detection and management of vitiligo lesions can be improved by estimating the likelihood of its development in transplant recipients and implementing a multidisciplinary approach for monitoring,” wrote the authors, from the departments of dermatology and biostatistics, at the Catholic University of Korea, Seoul.

Using claims data from South Korea’s National Health Insurance Service database, the investigators compared vitiligo incidence among 23,829 patients who had undergone solid organ transplantation (SOT) or HSCT between 2010 and 2017 versus that of 119,145 age- and sex-matched controls. At a mean observation time of 4.79 years in the transplant group (and 5.12 years for controls), the adjusted hazard ratio (AHR) for vitiligo among patients who had undergone any transplant was 1.73. AHRs for HSCT, liver transplants, and kidney transplants were 12.69, 1.63, and 1.50, respectively.

Patients who had undergone allogeneic HSCT (AHR, 14.43) or autologous transplants (AHR, 5.71), as well as those with and without GVHD (24.09 and 8.21, respectively) had significantly higher vitiligo risk than the control group.

Among those with GVHD, HSCT recipients (AHR, 16.42) and those with allogeneic grafts (AHR, 16.81) had a higher vitiligo risk than that of control patients.

In a subgroup that included 10,355 transplant recipients who underwent posttransplant health checkups, investigators found the highest vitiligo risk — AHR, 25.09 versus controls — among HSCT recipients with comorbid GVHD. However, patients who underwent SOT, autologous HSCT, or HSCT without GVHD showed no increased vitiligo risk in this analysis. “The results of health checkup data analysis may differ from the initial analysis due to additional adjustments for lifestyle factors and inclusion of only patients who underwent a health checkup,” the authors wrote.

Asked to comment on the results, George Han, MD, PhD, who was not involved with the study, told this news organization, “this is an interesting paper where the primary difference from previous studies is the new association between GVHD in hematopoietic stem cell transplant recipients and vitiligo.” Prior research had shown higher rates of vitiligo in HSCT recipients without making the GVHD distinction.

Although GVHD may not be top-of-mind for dermatologists in daily practice, he said, the study enhances their understanding of vitiligo risk in HSCT recipients. “In some ways,” Dr. Han added, “the association makes sense, as the activated T cells from the graft attacking the skin in the HSCT recipient follow many of the mechanisms of vitiligo, including upregulating interferon gamma and the CXCR3/CXCL10 axis.”

Presently, he said, dermatologists worry more about solid organ recipients than about HSCT recipients because the long-term immunosuppression required by SOT increases the risk of squamous cell carcinoma (SCC). “However, the risk of skin cancers also seems to be elevated in HSCT recipients, and in this case the basal cell carcinoma (BCC):SCC ratio is not necessarily reversed as we see in solid organ transplant recipients. So the mechanisms are a bit less clear. Interestingly, acute and chronic GVHD have both been associated with increased risks of BCC and SCC/BCC, respectively.”

Overall, Dr. Han said, any transplant recipient should undergo yearly skin checks not only for skin cancers, but also for other skin conditions such as vitiligo. “It would be nice to see this codified into official guidelines, which can vary considerably but are overall more consistent in solid organ transplant recipients than in HSCT recipients. No such guidelines seem to be available for HSCTs.”

The increased risk of vitiligo found in recipients of stem cell and solid organ transplants, especially those who develop graft-versus-host disease (GVHD), requires careful monitoring, according to authors of a study published online in JAMA Dermatology December 13.

In the cohort study, the greatest risk occurred with hematopoietic stem cell transplants (HSCTs) and in cases involving GVHD. Kidney and liver transplants carried slight increases in risk.

“The findings suggest that early detection and management of vitiligo lesions can be improved by estimating the likelihood of its development in transplant recipients and implementing a multidisciplinary approach for monitoring,” wrote the authors, from the departments of dermatology and biostatistics, at the Catholic University of Korea, Seoul.

Using claims data from South Korea’s National Health Insurance Service database, the investigators compared vitiligo incidence among 23,829 patients who had undergone solid organ transplantation (SOT) or HSCT between 2010 and 2017 versus that of 119,145 age- and sex-matched controls. At a mean observation time of 4.79 years in the transplant group (and 5.12 years for controls), the adjusted hazard ratio (AHR) for vitiligo among patients who had undergone any transplant was 1.73. AHRs for HSCT, liver transplants, and kidney transplants were 12.69, 1.63, and 1.50, respectively.

Patients who had undergone allogeneic HSCT (AHR, 14.43) or autologous transplants (AHR, 5.71), as well as those with and without GVHD (24.09 and 8.21, respectively) had significantly higher vitiligo risk than the control group.

Among those with GVHD, HSCT recipients (AHR, 16.42) and those with allogeneic grafts (AHR, 16.81) had a higher vitiligo risk than that of control patients.

In a subgroup that included 10,355 transplant recipients who underwent posttransplant health checkups, investigators found the highest vitiligo risk — AHR, 25.09 versus controls — among HSCT recipients with comorbid GVHD. However, patients who underwent SOT, autologous HSCT, or HSCT without GVHD showed no increased vitiligo risk in this analysis. “The results of health checkup data analysis may differ from the initial analysis due to additional adjustments for lifestyle factors and inclusion of only patients who underwent a health checkup,” the authors wrote.

Asked to comment on the results, George Han, MD, PhD, who was not involved with the study, told this news organization, “this is an interesting paper where the primary difference from previous studies is the new association between GVHD in hematopoietic stem cell transplant recipients and vitiligo.” Prior research had shown higher rates of vitiligo in HSCT recipients without making the GVHD distinction.

A significant number of patients with moderate-to-severe atopic dermatitis (AD) failed to achieve adequate disease control with systemic therapies over 12 months in a study of patient registry data, indicating a substantial degree of “therapeutic inertia,” the study’s lead author, Jonathan I. Silverberg, MD, PhD, MPH, reported.

The findings come from an analysis of real-world outcomes from the TARGET-DERM AD registry, which Dr. Silverberg, professor and director of clinical research and contact dermatitis in the department of dermatology at George Washington University, Washington, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. He characterized the findings as “patients just getting stuck with a therapy and not advancing when they need to.”

TARGET-DERM AD is a longitudinal observational study of people with AD at 39 academic centers in the United States and Canada. Dr. Silverberg and his coinvestigators evaluated the proportion of patients who were experiencing an inadequate response after receiving systemic therapy and continuing on the same treatment for 3-12 months. “These are patients who are receiving their first or advanced systemic therapy, and the question is, how long did they stay on it, even if they’re not doing so well?” Dr. Silverberg said.

The researchers identified and compared the proportions of patients not achieving moderate or optimal clinician-reported outcome targets on patients with AD treated with their first systemic therapy. Advanced systemic therapy (AST) included abrocitinib, dupilumab, tralokinumab, or upadacitinib, while conventional systemic therapy (CST) included methotrexate, cyclosporine, mycophenolate mofetil, azathioprine, and systemic corticosteroids.

Patients in TARGET-DERM AD were treated and maintained on their first systemic therapy (either advanced or conventional) for up to 12 months. They had a validated Investigator’s Global Assessment of AD (vIGA-AD) score of 3 or 4 less than 45 days prior to initiation of systemic therapy or up to 14 days afterward. They also had at least one vIGA-AD assessment 3-12 months after initiating treatment. Outcome measures included IGA (defined as a score of 2 or less, with an optional target of 0 or 1), BSA (defined as a 50% BSA improvement, with an optimal target BSA of 2% or less), and the Worst-Itch Numeric Rating Scale (defined as at least a 4-point reduction, with an optimal target of 1 or less).

The analysis included 445 patients with a mean age of 31 years at enrollment. More than half (62%) were female and 45% were non-Hispanic Whites. Most patients (92%) were on an AST, mainly dupilumab, with smaller proportions treated with either tralokinumab, upadacitinib, or abrocitinib. Fewer than 10% of patients in the registry were being treated with CSTs.

At 6 months, 37% and approximately 67% of the AST-treated patients had inadequate responses in terms of skin clearance and itch outcomes, respectively. At 12 months, these figures were about 30% and 66%, respectively. CST-treated patients showed a similar trend. For patients starting an AST on or after Sept. 21, 2021, when three additional AST options were available (tralokinumab, upadacitinib, and abrocitinib), the proportion of patients demonstrating an adequate response over 12 months was generally similar to the overall cohort of those on ASTs.

“These findings suggest a need for alternative therapies and management strategies in AD treatment,” concluded Dr. Silverberg, who chaired the RAD symposium.

Individuals with severe acne were considered less attractive, less worthy of friendship, and less likely to be hired for a job, compared with those who did not have acne, based on survey responses from more than 1300 individuals.

JAMA Network, 2023 American Medical Association

Self-stigma among people with acne has been examined in previous studies; however, “little is known about the prevalence and magnitude of stigmatizing attitudes of the general public toward individuals with acne,” wrote Ali Shields of Drexel University, Philadelphia, Pennsylvania, and her coauthors.

In the study, recently published in JAMA Dermatology, they reviewed survey data from 1357 adults aged 18 years and older who were identified through an online national research registry (ResearchMatch). The mean age of the participants was 42.4 years range). 67.7% were female.

Participants were randomly shown 1 of 12 standardized portraits of individuals that varied in skin tone, sex, and acne severity. They responded to questions about stigmatizing attitudes with respect to the portrait, including stereotype endorsement and desire for social distance.

With regard to social distance, survey participants were significantly less comfortable being friends with people with severe acne, compared with those who did not have acne (adjusted coefficient [aC], -0.28, P = .003). Compared with people without acne, participants also reported significantly less comfort in hiring someone with severe acne (aC, -0.33; P < .001), having physical contact (aC, -0.26; P = .006), dating (aC, -0.44; P = .004), and posting photos with that person on social media (aC, -0.50; P < .001).

With regard to common acne stereotypes, survey participants also rated individuals with severe acne as significantly more likely than those without acne to have poor hygiene and to be unattractive, unintelligent, unlikeable, immature, and untrustworthy (aCs, -1.04, -0.89, -0.42, -0.36, -0.52, and -0.40, respectively; P < .001 for all).

In a linear regression analysis, the researchers found no evidence of association modification by sex of the portraits presented, but found evidence that “the effect size of association of acne with stereotype endorsement was greater for individuals with dark skin.”

The findings were limited by several factors including the potential differences in degree of severity between images after the addition of acne because the baseline images were not exact controls for each other: Therefore comparisons between image sets based on skin tone or sex should be interpreted cautiously, the researchers noted. Other limitations included the homogeneous population of survey respondents and the inability to account for all aspects of stigma, they said.

However, the results illustrate the persistent stigma associated with acne and “highlight the need to identify approaches to reduce stigmatizing attitudes in the community and for adequate access to care, which might prevent negative downstream effects related to these stigmatizing attitudes,” the authors concluded.

Following the initial presentation, the lesion was initially considered an acquired port wine stain and the child was referred for laser treatment. Upon reassessment during laser treatment a few months later, the lesion had progressed to hyper- and hypopigmented plaques with associated tissue sclerosis and bone atrophy on the mid forehead, nose, and scalp. Patches of alopecia and atrophy were observed on the frontal scalp. The diagnosis was revised to linear morphea en coup de sabre and the child was referred to pediatric rheumatology and commenced treatment with methotrexate and oral corticosteroids.

Linear morphea, a rare connective tissue disorder, primarily affects girls in the first 2 decades of life. Lesions can initially present in many ways. Usually, they present as hypo- or hyperpigmented patches, but may also present as lichenoid uncolored or pink plaques resembling lichen striatus. There may also be erythematous patches mimicking a capillary malformation, as seen in our patient. A recent article reviewing the progression of the lesions from erythematous patches to sclerosis suggests it occurs between 3 and 7 months of age. Subsequent stages manifest as significant atrophy, hypo- and hyperpigmentation, and in severe cases, bone atrophy and deformity, often causing substantial cosmetic disfigurement and functional impairment.

Pathophysiologically, linear morphea involves a complex interplay of immunologic, vascular, and fibrotic processes. While the initial triggers remain elusive, dysregulated immune responses leading to endothelial injury, subsequent activation of fibroblasts and myofibroblasts, and excessive collagen deposition are implicated. Angiogenic disturbances exacerbate tissue ischemia, perpetuating the fibrotic cascade. Alterations in cytokine signaling pathways, particularly TGF-beta and interleukin-6, play pivotal roles in promoting fibrosis and modulating the inflammatory milieu.

Diagnosis of linear morphea en coup de sabre relies on clinical examination, imaging (ultrasonography, MRI, CT scan), and skin biopsy for histopathological analysis. Imaging helps evaluate tissue involvement, while histology reveals characteristic dermal sclerosis, collagen deposition, and inflammation. Early-stage histology may show telangiectatic changes, complicating its differentiation from capillary malformation.

Treatment aims to mitigate symptoms, halt disease progression, and improve cosmesis and functionality. This involves a multidisciplinary approach with systemic medications, phototherapy, physical therapy, and surgical interventions in severe cases. Early identification is crucial for systemic treatments such as methotrexate and systemic corticosteroids to arrest disease progression. Other adjunctive therapies include topical corticosteroids, calcineurin inhibitors, and phototherapy. Surgical procedures like tissue expansion or autologous fat grafting may address tissue atrophy and deformities.

Linear morphea en coup de sabre presents diagnostic and therapeutic challenges because of its rarity and variable clinical course. Collaborative efforts among dermatologists, rheumatologists, radiologists, and surgeons are essential for accurate diagnosis, evaluation, and tailored management. Continued research into pathogenesis and novel therapeutic agents is pivotal to enhance understanding and improve outcomes for those affected by this enigmatic dermatologic condition.

Following the initial presentation, the lesion was initially considered an acquired port wine stain and the child was referred for laser treatment. Upon reassessment during laser treatment a few months later, the lesion had progressed to hyper- and hypopigmented plaques with associated tissue sclerosis and bone atrophy on the mid forehead, nose, and scalp. Patches of alopecia and atrophy were observed on the frontal scalp. The diagnosis was revised to linear morphea en coup de sabre and the child was referred to pediatric rheumatology and commenced treatment with methotrexate and oral corticosteroids.

Linear morphea, a rare connective tissue disorder, primarily affects girls in the first 2 decades of life. Lesions can initially present in many ways. Usually, they present as hypo- or hyperpigmented patches, but may also present as lichenoid uncolored or pink plaques resembling lichen striatus. There may also be erythematous patches mimicking a capillary malformation, as seen in our patient. A recent article reviewing the progression of the lesions from erythematous patches to sclerosis suggests it occurs between 3 and 7 months of age. Subsequent stages manifest as significant atrophy, hypo- and hyperpigmentation, and in severe cases, bone atrophy and deformity, often causing substantial cosmetic disfigurement and functional impairment.

Pathophysiologically, linear morphea involves a complex interplay of immunologic, vascular, and fibrotic processes. While the initial triggers remain elusive, dysregulated immune responses leading to endothelial injury, subsequent activation of fibroblasts and myofibroblasts, and excessive collagen deposition are implicated. Angiogenic disturbances exacerbate tissue ischemia, perpetuating the fibrotic cascade. Alterations in cytokine signaling pathways, particularly TGF-beta and interleukin-6, play pivotal roles in promoting fibrosis and modulating the inflammatory milieu.

Diagnosis of linear morphea en coup de sabre relies on clinical examination, imaging (ultrasonography, MRI, CT scan), and skin biopsy for histopathological analysis. Imaging helps evaluate tissue involvement, while histology reveals characteristic dermal sclerosis, collagen deposition, and inflammation. Early-stage histology may show telangiectatic changes, complicating its differentiation from capillary malformation.

Treatment aims to mitigate symptoms, halt disease progression, and improve cosmesis and functionality. This involves a multidisciplinary approach with systemic medications, phototherapy, physical therapy, and surgical interventions in severe cases. Early identification is crucial for systemic treatments such as methotrexate and systemic corticosteroids to arrest disease progression. Other adjunctive therapies include topical corticosteroids, calcineurin inhibitors, and phototherapy. Surgical procedures like tissue expansion or autologous fat grafting may address tissue atrophy and deformities.

Linear morphea en coup de sabre presents diagnostic and therapeutic challenges because of its rarity and variable clinical course. Collaborative efforts among dermatologists, rheumatologists, radiologists, and surgeons are essential for accurate diagnosis, evaluation, and tailored management. Continued research into pathogenesis and novel therapeutic agents is pivotal to enhance understanding and improve outcomes for those affected by this enigmatic dermatologic condition.

Treatment with bimekizumab significantly improved symptoms in adults with palmoplantar pustulosis (PPP) and palmoplantar plaque psoriasis with pustules, in a case series of 21 individuals.

PPP is a type of pustular psoriasis that remains a treatment challenge, and available treatments for palmoplantar plaque psoriasis with pustules also “remain unsatisfactory,” according to Thierry Passeron, MD, PhD, of the dermatology service at Centre Hospitalier Universitaire de Nice (France), and colleagues. Bimekizumab, an anti-interleukin (IL)-17A and anti-IL-17F antibody therapy, has been used for psoriasis and psoriatic arthritis (PsA), but its effectiveness for PPP has not been studied, they said. In the United States, bimekizumab (Bimzelx), administered subcutaneously, was recently approved for treating moderate to severe plaque psoriasis in adults; in the European Union, it is approved for treating psoriasis, in addition to psoriatic arthritis, axial spondyloarthritis and ankylosing spondylitis.

In the case series published in JAMA Dermatology, Dr. Passeron and coinvestigators identified 11 adults with PPP and 10 with palmoplantar plaque psoriasis with pustules who were treated at one of seven tertiary dermatology centers in France from September 2022 through June 2023. PPP also has been associated with bone and joint inflammation in SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome.

All patients received bimekizumab for at least 3 months. The patients — 19 women and 2 men — ranged in age from 24 to 68 years (mean age, 46 years). The primary outcome was complete clearance, defined as an Investigator Global Assessment (IGA) score of 0.

A total of 17 patients achieved an IGA score of zero in 1-4 months. Over 3-6 months, three patients achieved an IGA score of 1 (almost clear), and one patient achieved an IGA score of 2 (mild).

Three patients with PPP also had acrodermatitis continua of Hallopeau; in these patients, nail involvement improved by 50%-70% after 4-6 months of bimekizumab use. Two patients with SAPHO experienced complete clearance of skin lesions associated with improvement in joint pain.

Four patients developed oral and genital candidiasis during treatment, but all were treated successfully with antifungals. None of the patients discontinued bimekizumab because of adverse events. “All patients are still receiving treatment, and their psoriatic lesions remain controlled,” the authors wrote.

“The rapid and consistent improvement observed in the present case series supports the effectiveness of bimekizumab therapy in managing PPP, palmoplantar plaque psoriasis with pustules, and SAPHO syndrome,” they said in their discussion.

The study findings were limited by several factors including the small sample size and short follow-up period, and by the inclusion of only patients with severe disease; and prospective, placebo-controlled studies are needed to confirm the results, the researchers noted.

However, the results suggest that bimekizumab could be a treatment approach for PPP, palmoplantar plaque psoriasis with pustules, and SAPHO syndrome, and warrant a prospective, randomized, placebo-controlled, randomized clinical trial to confirm the findings, they concluded.

Tape stripping, which allows sampling of the epidermis to the midgranular layer, is a valid, minimally invasive way to identify cutaneous biomarkers in patients with hidradenitis suppurative (HS), results from a novel study showed.

“Tape strips can provide important clues to when and which drugs to use in HS in patients with both early and late disease, which can change clinical practice,” corresponding study author Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview. “It is noninvasive and nonscarring,” she added.

Tape stripping has been validated in atopic dermatitis, psoriasis, and other dermatologic conditions in recent years. For the current study, which was published online in the Journal of the American Academy of Dermatology, and is believed to be the first of its kind, Dr. Guttman-Yassky and colleagues performed RNA sequencing from large D-Squame tape strips collected from lesional and nonlesional skin of 22 patients with HS and from 21 age- and sex-matched healthy controls. They correlated the expression of skin biomarkers between tape strips and a previously published gene-signature of HS biopsies. The mean age of patients with HS was 43 years, while the mean age of healthy controls was 35. The average International Hidradenitis Suppurativa Severity Score System (IHS4) score of the HS cohort was 36.

Consistent with published studies, the researchers found that tape strips identified an overall higher inflammatory burden in HS. Specifically, they observed an upregulation of known cytokines within the following pathways: Th1 (such as IFNG, CXCL9/10/11, and CCR5); Th17 (such as interleukin [IL]-17A/F, IL12B, IL23A, CAMP, and CCL20); Th2 (such as IL4R, IL13/IL31/IL10, CCR4, CCL7/CCL13/CCL24, TNFSF4/OX40L, and TNFRSF4/OX40); and Th22 (such as IL22 and IL32).

The researchers also found that the expression of Th17 and tumor necrosis factor (TNF)–alpha pathways were highly correlated between tape strips and biopsies and that HS clinical severity was significantly associated with expression of biomarkers, such as TNF-alpha, IL17A/F, OX40, JAK1-3, and IL4R in HS lesional and/or nonlesional skin.

“It was quite unexpected that we are able to identify, using a minimally invasive approach that samples only the upper layers of the epidermis, products and processes that are considered to be deeper-situated, such as IL-17, and other immune markers,” Dr. Guttman-Yassky said in the interview. “We were also surprised to see how well the tape-stripped–derived skin molecular profile correlated with that of biopsies, as well as how well it correlated with the clinical disease severity of HS.”

Also surprising, she added, was that the biomarkers in nonlesional tape-stripped skin, such as IL-17 and TNF alpha, “show high correlations with disease severity and provide clues to early disease.”

If using tape strips in HS is validated in larger cohort studies, the potential cost implications of using this approach in practice remain unclear, Dr. Guttman-Yassky said. “It is currently not cheap, but we are hoping that one day, we can provide a means to diagnose the disease and treat it early, and appropriately, utilizing this approach,” she commented. “We are excited about the applicability of this study to the early treatment and longitudinal follow up of HS with drugs that are targeting specific immune molecules and pathways,” she said, adding that it will also be useful for helping determine which drug should be used for which patient.

She and her co-authors acknowledged certain limitations of the study, including its small sample size and the fact that tape stripping is limited to the epidermis.

Asked to comment on the study, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, said the findings “have important potential implications for our ability to one day personalize treatments for a patient with early HS in a minimally invasive way.”

As the study authors point out, she added, “tape strips only allow sampling of the epidermis, which is limiting in a disease like HS where much of the disruption is in the dermis with deep nodules and dermal tunnels. However, our overall goal should be to catch patients in the early stages of their disease before the occurrence of irreversible tissue damage such as dermal tunnels. Thus, the ongoing campaign for early diagnosis and early intervention by various stakeholders in the field of HS can help mitigate the impact of this inherent limitation of tape strips. It will be exciting to see larger studies that investigate tape strip results in relation to clinical phenotypes, disease progression, and therapeutic responses.”

The study was funded by an International Dermatology Outcome Measures Hidradenitis Suppurativa Grant. Dr. Guttman-Yassky disclosed that she has been a consultant to, an adviser for, and has received research grants from many pharmaceutical companies. Of the remaining authors, 2 also had multiple disclosures and 11 had no disclosures. Dr. Hsiao disclosed that she is a member of the board of directors for the Hidradenitis Suppurativa Foundation. She has also served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

Combined therapy with rituximab and omalizumab appears to be well tolerated, and improves outcomes and accelerates time to remission in patients with refractory bullous pemphigoid who do not respond to rituximab alone, results of a case series suggest.

Bullous pemphigoid (BP) is a rare, chronic, inflammatory, blistering disease that mainly occurs in people in their 50s through their 70s. BP has high morbidity and mortality, especially in people with comorbidities common to the elderly, yet no Food and Drug Administration–approved therapies for BP exist, Stephanie T. Le, MD, a dermatologist in the department of dermatology of the University of California, Davis, told this publication.

All participants received 1000 mg intravenous rituximab on days 0 and 15. In addition to rituximab, seven patients received subcutaneous high-dose omalizumab (300 mg every 2 weeks); and three patients received low-dose omalizumab (300 mg every 4 weeks or 150 mg every 2 weeks).

After a mean of 2.1 months, all patients in the high-dose omalizumab-plus-rituximab group had achieved complete remission. By contrast, all patients in the low-dose omalizumab-plus-rituximab group improved after a mean of 13 months, and none achieved complete remission.

At 3 months, all study participants were rated as being very much improved. All four patients in the high-dose omalizumab group who tapered omalizumab dosage or frequency had flare-ups within 1-3 months that resolved when they restarted the medication. Among patients who achieved complete remission, 4 of 7 required rituximab redosing between 6 and 16 months later. Rituximab alone did not achieve remission: Three patients needed to add high-dose omalizumab. All reported adverse effects were mild.

Alternatives to Corticosteroids Are Needed

For BP, “with no FDA-approved therapies available, corticosteroids remain first line for acute flares. However, prolonged corticosteroid use is associated with multiple adverse effects, including increased susceptibility to infection, osteoporosis, and diabetes mellitus,” Dr. Le pointed out. “Patients with BP who are treated with high-dose corticosteroids have significantly increased mortality and have very poor 1-year survival.

“Rituximab and omalizumab dual therapy offers another potential treatment option for severe or treatment-refractory BP,” she added. “We are hopeful that other physicians will adopt this therapy.”

The authors acknowledged limitations of the study, including its retrospective design, small sample size, lack of standardized intervals between rituximab and omalizumab, and variation in concurrent therapies, and they recommended further related research.

No conflicts of interest were reported. No funding details were provided.

Follicular occlusion, mast cell disease, and eczema were common presentations among patients with hypermobile Ehlers-Danlos syndrome (hEDS), in a study of nearly 500 individuals.

The genetic cause of hEDS, a common inherited connective tissue disorder, remains unknown, wrote Alan Snyder, MD, of the department of dermatology and dermatologic surgery at Medical University of South Carolina, Charleston, and colleagues.

Previous research suggests that changes in dermal mechanics predispose these patients to a range of skin conditions including mast cell activation disorder (MCAD) spectrum and chronic spontaneous urticaria, abnormal scars or wound healing, piezogenic papules, dyshidrosis, skin laxity or softness, easy bruising, local anesthesia resistance, keratosis pilaris, striae, and hidradenitis suppurativa, the researchers wrote.

However, data on these and other dermatologic manifestations of hEDS are limited, they said.

The diagnosis of hEDS will continue to be made more frequently and carefully, as the condition becomes more recognized and understood in the medical community, especially with anticipated capabilities of genetic testing, Dr. Snyder said in an interview.

“Being able to be aware of disease-specific comorbidities, such as those discovered in this study, allows providers to better stratify phenotypes and improve patient disease co-management,” he said.

In the study, published in the Journal of the American Academy of Dermatology, the researchers reviewed data on 1,364 patients with ICD-10 or ICD-9 codes for hEDS or EDS unspecified who were seen at a single institution between June 2005 and May 2022. Most of the patients were White (95.4%) and female (86.7%); the average age was 29.2 years.

Of the 1,364 patients included in the chart review, 497 (36.4%) had documented skin manifestations. Of these, 118 (24.2%) had disorders of follicular occlusion (12 had hidradenitis suppurativa, 32 had folliculitis, and 74 had acne); 112 (23%) had eczema or atopic dermatitis, 98 (19.7%) had mast cell disorder, 32 (6.4%) had psoriasis, and 32 (6.4%) had wound healing issues (16 had hypertrophic keloids/scarring, 5 had abscesses, 3 had abnormal bruising, and 8 had other would healing issues).

The study also included results of a multiple-choice patient survey from 1,354 individuals. In the survey, approximately two-thirds of patients reported abnormal scarring, abnormal wound healing, and cutaneous laxity (61.7%, 69.0%, and 71.0%, respectively).

The findings were limited by several factors including the retrospective study design, lack of testing to confirm hEDS diagnosis, and the potential interdisciplinary selection bias for diagnoses, the authors noted.

However, the results support previous studies showing increased rates of occlusive conditions in hEDS and higher rates of acne, folliculitis, and psoriasis, and highlight the need for clinician education to manage patients and promote better outcomes, the researchers concluded.

Data Enhance Clinical Awareness

“Given the increasingly understood relation between TH2-directed and mast-cell mediated diseases and hEDS, it was not necessarily a surprise to find the increased prevalence of atopy and mast cell disease, but rather an interesting confirmation, within the limitations that exist with retrospective chart review,” Dr. Snyder told this news organization. “While it may make some intuitive sense that certain cohorts with higher risk of HS may have a higher risk of acne, this had not been reported in the literature to date,” he noted. “Given the high levels of patient reported issues with scarring and wound healing, I was surprised that so few analogous diagnoses were physician-reported in the medical records.”

In clinical practice, “health care professionals and patients need to be aware hEDS is associated with high rates of eczematous, mast-cell mediated and follicular occlusive cutaneous disorders,” Dr. Snyder said in an interview. “There seems to be a discrepancy between patients and physician awareness of scarring or wound healing issues in this patient population,” he added.

Looking ahead, “we need to better research and characterize the various hEDS phenotypes to understand who is at highest risk for various TH2-mediated or follicular occlusive disorders,” said Dr. Snyder. “Moreover, a greater understanding is needed of the wound healing inadequacies that predispose these patients to poor outcomes during dermatologic surgery,” he said.

The study was supported by the Ehlers-Danlos Society and the Milton and Tamar Maltz Family Foundation. The researchers had no financial conflicts to disclose.
