TORONTO — With rates of childhood obesity increasing to the point of becoming a public health concern, related skin conditions are also on the rise in the pediatric population, results of new research show.

The retrospective cohort study found markedly higher rates of skin infections, atopic dermatitis (AD), and acanthosis nigricans among children with overweight, compared with children with average weight.

“Many conditions associated with obesity are strong predictors of cardiovascular mortality as these children age, so doctors can play a key role in advocating for weight loss strategies in this population,” lead study author Samantha Epstein, third-year medical student at Case Western Reserve University, Cleveland, Ohio, said in an interview. The findings were presented at the annual meeting of the Society for Pediatric Dermatology.

Previous research has linked obesity, a chronic inflammatory condition, to psoriasis, AD, hidradenitis suppurativa (HS), acne vulgaris, infections, and rosacea in adults. However, there’s scant research exploring the connection between obesity and cutaneous conditions in children.

According to the Cleveland Clinic, childhood obesity is defined as a body mass index, which is weight in kg divided by the square of height in m², at or above the 95th percentile for age and sex in children aged 2 years or older.

For the study, Ms. Epstein and coauthor Sonal D. Shah, MD, associate professor, Department of Dermatology, Case Western Reserve University, and a board-certified pediatric dermatologist accessed a large national research database and used diagnostic codes to identify over 1 million children (mean age, 8.5 years). Most (about 44%) were White; about one-quarter were Black. The groups were propensity matched, so there were about equal numbers of youngsters with and without obesity and of boys and girls.

They collected data on AD, HS, rosacea, psoriasis, and acanthosis nigricans (a thickened purplish discoloration typically found in body folds around the armpits, groin, and neck). They also gathered information on comorbidities.

Acanthosis nigricans, which is linked to metabolic syndrome, type 2 diabetes, and insulin resistance , was more prevalent among children with obesity (20,885 cases in the with-obesity group and 336 in the without-obesity group, for a relative risk [RR] of 62.16 and an odds ratio [OR] of 64.38).

Skin and subcutaneous tissue infections were also more common among those with obesity (14,795 cases) vs 4720 cases among those without obesity (RR, 3.14; OR, 3.2). As for AD, there were 11,892 cases in the with-obesity group and 2983 in the without-obesity group (RR, 3.99; OR, 4.06). There were 1166 cases of psoriasis among those with obesity and 408 among those without obesity (RR, 2.86; OR, 2.88).

HS (587 cases in the with-obesity group and 70 in the without-obesity group; RR, 8.39; OR, 8.39) and rosacea (351 in the with-obesity group and 138 in the without-obesity group; RR, 2.54; OR, 2.55) were the least common skin conditions.

Higher Comorbidity Rates

Compared with their average-weight counterparts, the children with obesity had higher rates of comorbidities, including type 2 diabetes. Ms. Epstein noted that children with diabetes and obesity had increased risks for every skin condition except for infections of the skin and subcutaneous tissue when compared with children without obesity. 

Such infections were the most common skin conditions among children without obesity. “This was expected just due to the fact that children are outside, they’re playing in the grass and the dirt, and they get infected,” said Ms. Epstein. Still, these infections were three times more common in youngsters with obesity.

Although acanthosis nigricans is “highly correlated” with type 2 diabetes, “not as many children as we would expect in this population have developed type 2 diabetes,” said Ms. Epstein. This might make some sense, though, because these children are still quite young. “When dermatologists recognize this skin condition, they can advocate for weight loss management to try to prevent it.”

Other conditions seen more often in the overweight children with overweight included: hypertension, hyperlipidemia, obstructive sleep apnea, polycystic ovarian syndrome, attention-deficit/hyperactivity disorder, major depressive disorder, depressive episodes, and anxiety (all P < .001).

Commenting on the results, Sonia Havele, MD, a pediatrician and dermatology resident at Children’s Mercy Hospital, Kansas City, Missouri, said in an interview that the study reflects trends that she and her colleagues see in clinic: There are more common skin conditions in their patients with obesity.

She agreed that it offers an opening for education. “The results of this study highlight the opportunity we have as pediatric dermatologists to provide additional counseling on obesity and offer referrals to our colleagues in endocrinology, gastroenterology, and nutrition if needed.”

No conflicts of interest were reported.

WASHINGTON — The chronic, excessive fragility of aging and sun-damaged skin has a name in the medical literature: dermatoporosis. This identification is helpful because it validates patients’ suffering and conveys the skin’s vulnerability to serious medical complications, said Adam Friedman, MD, at the ElderDerm conference on dermatology in the older patient.

Key features of dermatoporosis include atrophic skin, solar purpura, white pseudoscars, easily acquired skin lacerations and tears, bruises, and delayed healing. “We’re going to see more of this, and it will more and more be a chief complaint of patients,” said Dr. Friedman, professor and chair of dermatology at George Washington University (GWU) in Washington, and co-chair of the meeting. GWU hosted the conference, describing it as a first-of-its-kind meeting dedicated to improving dermatologic care for older adults.

Likely Pathophysiology

Advancing age and chronic ultraviolet (UV) radiation exposure are the chief drivers of dermatoporosis. In addition to UVA and UVB light, other secondary drivers include genetic susceptibility, topical and systematic corticosteroid use, and anticoagulant treatment.

Its pathogenesis is not well described in the literature but is easy to envision, Dr. Friedman said. For one, both advancing age and exposure to UV light lead to a reduction in hygroscopic glycosaminoglycans, including hyaluronate (HA), and the impact of this diminishment is believed to go “beyond [the loss of] buoyancy,” he noted. Researchers have “been showing these are not just water-loving molecules, they also have some biologic properties” relating to keratinocyte production and epidermal turnover that appear to be intricately linked to the pathogenesis of dermatoporosis. 

HAs have been shown to interact with the cell surface receptor CD44 to stimulate keratinocyte proliferation, and low levels of CD44 have been reported in skin with dermatoporosis compared with a younger control population. (A newly characterized organelle, the hyaluronosome, serves as an HA factory and contains CD44 and heparin-binding epidermal growth factor, Dr. Friedman noted. Inadequate functioning may be involved in skin atrophy.) 

Advancing age also brings an increase in matrix metalloproteinases (MMPs)–1, –2, and –3, which are “the demolition workers of the skin,” and downregulation of a tissue inhibitor of MMPs, he said. 

Adding insult to injury, dermis-penetrating UVA also activates MMPs, “obliterating collagen and elastin.” UVB generates DNA photoproducts, including oxidative stress and damaging skin cell DNA. “That UV light induces breakdown [of the skin] through different mechanisms and inhibits buildup is a simple concept I think our patients can understand,” Dr. Friedman said.
 

Multifaceted Treatment

For an older adult, “there is never a wrong time to start sun-protective measures” to prevent or try to halt the progression of dermatoporosis, Dr. Friedman said, noting that “UV radiation is an immunosuppressant, so there are many good reasons to start” if the adult is not already taking measures on a regular basis.

Potential treatments for the syndrome of dermatoporosis are backed by few clinical studies, but dermatologists are skilled at translating the use of products from one disease state to another based on understandings of pathophysiology and mechanistic pathways, Dr. Friedman commented in an interview after the meeting. 

For instance, “from decades of research, we know what retinoids will do to the skin,” he said in the interview. “We know they will turn on collagen-1 and -3 genes in the skin, and that they will increase the production of glycosaminoglycans ... By understanding the biology, we can translate this to dermatoporosis.” These changes were demonstrated, for instance, in a small study of topical retinol in older adults.

Studies of topical alpha hydroxy acid (AHA), moreover, have demonstrated epidermal thickening and firmness, and “some studies show they can limit steroid-induced atrophy,” Dr. Friedman said at the meeting. “And things like lactic acid and urea are super accessible.”

Topical dehydroepiandrosterone is backed by even less data than retinoids or AHAs are, “but it’s still something to consider” as part of a multimechanistic approach to dermatoporosis, Dr. Friedman shared, noting that a small study demonstrated beneficial effects on epidermal atrophy in aging skin. 

The use of vitamin D analogues such as calcipotriene, which is approved for the treatment of psoriasis, may also be promising. “One concept is that [vitamin D analogues] increase calcium concentrations in the epidermis, and calcium is so central to keratinocyte differentiation” and epidermal function that calcipotriene in combination with topical steroid therapy has been shown to limit skin atrophy, he noted.

Nutritionally, low protein intake is a known problem in the older population and is associated with increased skin fragility and poorer healing. From a prevention and treatment standpoint, therefore, patients can be counseled to be attentive to their diets, Dr. Friedman said. Experts have recommended a higher protein intake for older adults than for younger adults; in 2013, an international group recommended a protein intake of 1-1.5 g/kg/d for healthy older adults and more for those with acute or chronic illness.

“Patients love talking about diet and skin disease ... and they love over-the-counter nutraceuticals as well because they want something natural,” Dr. Friedman said. “I like using bioflavonoids in combination with vitamin C, which can be effective especially for solar purpura.”

Skin Injury and Wound Prevention

In addition to recommending gentle skin cleansers and daily moisturizing, dermatologists should talk to their older patients with dermatoporosis about their home environments. “What is it like? Is there furniture with sharp edges?” Dr. Friedman advised. If so, could they use sleeves or protectors on their arms or legs “to protect against injury?”

In a later meeting session about lower-extremity wounds on geriatric patients, Michael Stempel, DPM, assistant professor of medicine and surgery and chief of podiatry at GWU, said that he was happy to hear the term dermatoporosis being used because like diabetes, it’s a risk factor for developing lower-extremity wounds and poor wound healing. 

He shared the case of an older woman with dermatoporosis who “tripped and skinned her knee against a step and then self-treated it for over a month by pouring hydrogen peroxide over it and letting air get to it.” The wound developed into “full-thickness tissue loss,” said Dr. Stempel, also medical director of the Wound Healing and Limb Preservation Center at GWU Hospital. 

Misperceptions are common among older patients about how a simple wound should be managed; for instance, the adage “just let it get air” is not uncommon. This makes anticipatory guidance about basic wound care — such as the importance of a moist and occlusive environment and the safe use of hydrogen peroxide — especially important for patients with dermatoporosis, Dr. Friedman commented after the meeting.

Dermatoporosis is quantifiable, Dr. Friedman said during the meeting, with a scoring system having been developed by the researchers in Switzerland who originally coined the term. Its use in practice is unnecessary, but its existence is “nice to share with patients who feel bothered because oftentimes, patients feel it’s been dismissed by other providers,” he said. “Telling your patients there’s an actual name for their problem, and that there are ways to quantify and measure changes over time, is validating.” 

Its recognition as a medical condition, Dr. Friedman added, also enables the dermatologist to bring it up and counsel appropriately — without a patient feeling shame — when it is identified in the context of a skin excision, treatment of a primary inflammatory skin disease, or management of another dermatologic problem.

Dr. Friedman disclosed that he is a consultant/advisory board member for L’Oréal, La Roche-Posay, Galderma, and other companies; a speaker for Regeneron/Sanofi, Incyte, BMD, and Janssen; and has grants from Pfizer, Lilly, Incyte, and other companies. Dr. Stempel reported no disclosures.

“Patients love talking about diet and skin disease ... and they love over-the-counter nutraceuticals as well because they want something natural,” Dr. Friedman said. “I like using bioflavonoids in combination with vitamin C, which can be effective especially for solar purpura.”

Skin Injury and Wound Prevention

In addition to recommending gentle skin cleansers and daily moisturizing, dermatologists should talk to their older patients with dermatoporosis about their home environments. “What is it like? Is there furniture with sharp edges?” Dr. Friedman advised. If so, could they use sleeves or protectors on their arms or legs “to protect against injury?”

In a later meeting session about lower-extremity wounds on geriatric patients, Michael Stempel, DPM, assistant professor of medicine and surgery and chief of podiatry at GWU, said that he was happy to hear the term dermatoporosis being used because like diabetes, it’s a risk factor for developing lower-extremity wounds and poor wound healing. 

He shared the case of an older woman with dermatoporosis who “tripped and skinned her knee against a step and then self-treated it for over a month by pouring hydrogen peroxide over it and letting air get to it.” The wound developed into “full-thickness tissue loss,” said Dr. Stempel, also medical director of the Wound Healing and Limb Preservation Center at GWU Hospital. 

Misperceptions are common among older patients about how a simple wound should be managed; for instance, the adage “just let it get air” is not uncommon. This makes anticipatory guidance about basic wound care — such as the importance of a moist and occlusive environment and the safe use of hydrogen peroxide — especially important for patients with dermatoporosis, Dr. Friedman commented after the meeting.

Dermatoporosis is quantifiable, Dr. Friedman said during the meeting, with a scoring system having been developed by the researchers in Switzerland who originally coined the term. Its use in practice is unnecessary, but its existence is “nice to share with patients who feel bothered because oftentimes, patients feel it’s been dismissed by other providers,” he said. “Telling your patients there’s an actual name for their problem, and that there are ways to quantify and measure changes over time, is validating.” 

Its recognition as a medical condition, Dr. Friedman added, also enables the dermatologist to bring it up and counsel appropriately — without a patient feeling shame — when it is identified in the context of a skin excision, treatment of a primary inflammatory skin disease, or management of another dermatologic problem.

Dr. Friedman disclosed that he is a consultant/advisory board member for L’Oréal, La Roche-Posay, Galderma, and other companies; a speaker for Regeneron/Sanofi, Incyte, BMD, and Janssen; and has grants from Pfizer, Lilly, Incyte, and other companies. Dr. Stempel reported no disclosures.

TOPLINE: 

Spironolactone may benefit women of childbearing age with mild hidradenitis suppurativa (HS), especially if initiated early, according to the results of a single-center retrospective study.

METHODOLOGY:

• This retrospective study included 157 women (median age, 36.5 years) with HS who received spironolactone for at least 3 months between 2000 and 2021 at Michigan Medicine outpatient dermatology clinics. The majority of patients were White (59%) or Black (37%) individuals.
• The median prescribed dose was 100 mg/d, the most common dose was 50-100 mg/d, and the median time spironolactone was initiated was 8.8 years after HS was diagnosed.
• Improvement status was classified on the basis of objective clinician assessments, including documented reductions in the lesion count, pain, and symptoms.

TAKEAWAY:

• Overall, 31 patients (20%) showed improvements with spironolactone treatment.
• A shorter duration between the diagnosis of HS and the initiation of spironolactone was associated with improvement (P = .047).
• Axillary involvement (P = .003), the use of intralesional steroids (P = .015), previous treatments (P = .023), and previous treatment failures (P = .030) were linked to a lack of improvement with spironolactone.
• Patients with Hurley stage III were 85% less likely to experience improvement with spironolactone (P = .036).

IN PRACTICE:

Spironolactone, which has antiandrogenic properties, “may be beneficial for patients with mild HS, notably those at Hurley stage I if implemented early as a primary or ancillary treatment,” the authors concluded, adding that prospective, multicenter studies are needed to “elucidate further the safety and efficacy of spironolactone for treating HS.”

SOURCE:

The study was led by Suma V. Gangidi, BS, Carle Illinois College of Medicine, University of Illinois Urbana-Champaign, and was published online in the International Journal of Women’s Dermatology.

LIMITATIONS:

Retrospective design can introduce inherent biases, including the potential for missing or misclassified data. Additionally, the study was conducted at a single center, which may limit the generalizability, and findings were also limited by lack of standardized objective measures for assessing treatment improvement, presence of confounding variables from concomitant treatments, small sample size, and potential multicollinearity.

DISCLOSURES:

This study did not receive any funding. One author declared ties with various pharmaceutical companies. The other authors declared no conflicts of interest.

Skin manifestations are common in the vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome and present early in the disease course. Additionally, the most common histologic findings include leukocytoclastic vasculitis, neutrophilic dermatosis, and perivascular dermatitis; different variants in the UBA1 gene are associated with specific skin manifestations.

Those are key findings from a cohort study of 112 patients with VEXAS published online in JAMA Dermatology. The study, conducted by researchers at the National Institutes of Health (NIH) and several other institutions, aimed to define the spectrum of cutaneous manifestations in VEXAS in association with genetic, histologic, and other clinical findings.

Edward W. Cowen, MD, MHSc

First described in 2020, VEXAS syndrome is an adult-onset multisystem disease that can pose a diagnostic challenge to clinicians, the study’s corresponding author, Edward W. Cowen, MD, MHSc, of the dermatology branch at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), said in an interview. The disease is caused by pathogenic variants in the UBA1 gene, located on the X chromosome. Affected individuals exhibit a wide range of manifestations, including cytopenia/myelodysplasia, multiorgan systemic inflammation, and cutaneous involvement.

“Patients may present to a variety of disease specialists depending on their symptoms and providers may not immediately consider a genetic etiology in an older individual,” Dr. Cowen said in an interview. “Although skin involvement occurs in more than 80% of patients, it is pleomorphic and may resemble a variety of other conditions such as vasculitis and Sweet syndrome.”

To better understand the cutaneous manifestations of VEXAS syndrome, the researchers evaluated data from 112 patients with VEXAS-defining genetic variants in the UBA1 gene between 2019 and 2023. Of the 112 patients, 73 underwent medical record review only, and 39 were prospectively evaluated at NIH. All but one of the patients were men, 94% were White individuals, and their mean age was 64 years. Skin involvement occurred in 83% of cases and was the most common presenting feature of VEXAS in 61% of cases.

Of the 64 histopathologic reports available from 60 patients, the main skin histopathologic findings were leukocytoclastic vasculitis in 23 patients (36%), neutrophilic dermatosis in 22 patients (34%), and perivascular dermatitis in 19 patients (30%). According to Dr. Cowen, one key histologic finding was a distinct pattern of “histiocytoid” dermal neutrophilic inflammation, which was present in 13 of 15 specimens (86%) that underwent central re-review. “This pattern can occasionally also be seen in patients with Sweet syndrome, unrelated to VEXAS, but was a hallmark feature found in the majority of skin biopsies of patients with VEXAS,” he said.

“Together with another pathologic finding, leukocytoclasia, these features can be useful clues to alert the pathologist to a potential diagnosis of VEXAS. This myeloid predominant pattern of skin inflammation was also most strongly associated with the leucine pathogenic variant of the UBA1 gene.” In contrast, cutaneous vasculitis was most strongly associated with the valine pathogenic variant of UBA1. “This is important because the valine variant has been previously independently linked to decreased survival,” he said.

In findings related to pathogenic genetic variants, the researchers observed that the p.Met41Leu variant was most frequently associated with neutrophilic dermal infiltrates in 14 of 17 patients (82%) with this variant and often resembled histiocytoid Sweet syndrome. In addition, the p.Met41Val variant was associated with vasculitic lesions in 11 of 20 patients (55%) with this variant and with a mixed leukocytic infiltrate in 17 of these 20 patients (85%).
 

Treatment Outcomes

In the realm of therapies, skin manifestations improved in 67 of 73 patients (92%) treated with oral prednisone, while treatment with the interleukin-1 receptor antagonist anakinra improved cutaneous disease in 9 of the 16 (56%) who received it. However, 12 (75%) of those who received anakinra developed severe injection-site reactions, including ulceration in two patients and abscess formation in one patient.

Dr. Cowen noted that VEXAS is associated with high mortality (22% in this cohort), and a high degree of suspicion is required to diagnose patients with VEXAS before significant end organ damage has occurred. “This diagnosis should be considered in all older male patients who present with neutrophilic dermatosis — particularly histiocytoid Sweet syndrome, vasculitis, or leukocytoclasia without vasculitis. Patients who appear to have isolated skin involvement may have cytopenias and acute phase reactants. Therefore, complete blood count with differential and ESR and CRP should be considered to investigate for macrocytosis, cytopenias, and systemic inflammation.”

He acknowledged certain limitations of the study, including the fact that many patients were first evaluated at the NIH after having disease symptoms for many months or years. “It is possible that patients with VEXAS referred to the NIH, either for genetic testing or in person evaluation, represent a population with more aggressive disease.”

Christine Ko, MD, professor of dermatology and pathology at Yale University, New Haven, Connecticut, who was asked to comment on the study, emphasized the importance of the UBA1 mutation in the diagnosis of this complex syndrome. “Dermatologists should be aware of VEXAS syndrome as the majority of patients present with skin lesions, which can range from urticarial to Sweet syndrome–like to palpable purpura,” Dr. Ko said.

“Chondritis and periorbital edema, sometimes unilateral, are also associated. Histopathologic clues include a predominantly histiocytoid infiltrate,” she noted. In addition, “the prominent myxoid stroma around blood vessels and adnexal structures as a clue to VEXAS syndrome surprised me; I had not read that before.”

The study was supported by the Intramural Research Program of NIAMS. One of the study authors reported personal fees from Alexion, Novartis, and Sobi outside of the submitted work. No other disclosures were reported. Dr. Ko reported having no disclosures.

TOPLINE:

Bimekizumab, currently approved for treating psoriasis, was well tolerated and reduced abscesses and the number of inflammatory nodules in patients with moderate to severe hidradenitis suppurativa (HS), in two phase 3 studies.

METHODOLOGY:

• To assess the efficacy and safety of bimekizumab, an interleukin (IL)-17A and IL-17F antagonist, 320 mg for HS, researchers conducted two 48-week phase 3 trials BE HEARD I (n = 505) and II (n = 509), which enrolled patients with moderate to severe HS and a history of inadequate response to systemic antibiotics.
• Patients were randomly assigned to one of four groups: Bimekizumab every 2 weeks, bimekizumab every 2 weeks for 16 weeks followed by every 4 weeks of dosing, bimekizumab every 4 weeks, or placebo for 16 weeks followed by bimekizumab every 2 weeks.
• The primary outcome was an HS clinical response of at least 50% (HiSCR50) at week 16, defined as at least a 50% reduction in total abscess and inflammatory nodule count.

TAKEAWAY:

• A higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved an HiSCR50 response at week 16 in BE HEARD I (48% vs 29%; odds ratio [OR], 2.23; P = .006) and II (52% vs 32%; OR, 2.29; P = .0032) trials.
• Patients receiving bimekizumab every 4 weeks also achieved a higher HiSCR50 response at week 16 vs placebo in the BE HEARD II trial (54% vs 32%; OR, 2.42; P = .0038).
• At week 16, a higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved at least a 75% HiSCR (HiSCR75) in both trials, and a higher proportion of those receiving bimekizumab every 4 weeks achieved HiSCR75 in the BE HEARD II trial.
• At week 48, 45%-68% of patients achieved HiSCR50 in both trials.
• Patients who received bimekizumab vs placebo for the initial 16 weeks had greater improvements in patient-reported outcomes, and bimekizumab was well tolerated with a low number of serious or severe treatment-emergent adverse events.

IN PRACTICE:

“Bimekizumab was well tolerated by patients with hidradenitis suppurativa and produced rapid and deep clinically meaningful responses that were maintained up to 48 weeks,” the authors wrote. “These data support the use of bimekizumab as a promising new therapeutic option for patients with moderate to severe hidradenitis suppurativa.”

SOURCE:

Alexa B. Kimball, MD, MPH, from Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, led this study, which was published online in The Lancet.

LIMITATIONS:

The placebo-controlled part of this trial was relatively short at 16 weeks and may affect the interpretation of later efficacy data, there was a lack of an active comparator group, and the efficacy of treatment was evaluated in the presence of rescue treatment with systemic antibiotics.

DISCLOSURES:

The studies were funded by bimekizumab manufacturer UCB Pharma. Seven authors disclosed being current or former employees of UCB Pharma. Other authors reported several ties with many companies, including UCB Pharma.

• A higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved an HiSCR50 response at week 16 in BE HEARD I (48% vs 29%; odds ratio [OR], 2.23; P = .006) and II (52% vs 32%; OR, 2.29; P = .0032) trials.
• Patients receiving bimekizumab every 4 weeks also achieved a higher HiSCR50 response at week 16 vs placebo in the BE HEARD II trial (54% vs 32%; OR, 2.42; P = .0038).
• At week 16, a higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved at least a 75% HiSCR (HiSCR75) in both trials, and a higher proportion of those receiving bimekizumab every 4 weeks achieved HiSCR75 in the BE HEARD II trial.
• At week 48, 45%-68% of patients achieved HiSCR50 in both trials.
• Patients who received bimekizumab vs placebo for the initial 16 weeks had greater improvements in patient-reported outcomes, and bimekizumab was well tolerated with a low number of serious or severe treatment-emergent adverse events.

IN PRACTICE:

“Bimekizumab was well tolerated by patients with hidradenitis suppurativa and produced rapid and deep clinically meaningful responses that were maintained up to 48 weeks,” the authors wrote. “These data support the use of bimekizumab as a promising new therapeutic option for patients with moderate to severe hidradenitis suppurativa.”

Alexa B. Kimball, MD, MPH, from Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, led this study, which was published online in The Lancet.

LIMITATIONS:

The placebo-controlled part of this trial was relatively short at 16 weeks and may affect the interpretation of later efficacy data, there was a lack of an active comparator group, and the efficacy of treatment was evaluated in the presence of rescue treatment with systemic antibiotics.

DISCLOSURES:

The studies were funded by bimekizumab manufacturer UCB Pharma. Seven authors disclosed being current or former employees of UCB Pharma. Other authors reported several ties with many companies, including UCB Pharma.

TOPLINE:

Bimekizumab, currently approved for treating psoriasis, was well tolerated and reduced abscesses and the number of inflammatory nodules in patients with moderate to severe hidradenitis suppurativa (HS), in two phase 3 studies.

METHODOLOGY:

• To assess the efficacy and safety of bimekizumab, an interleukin (IL)-17A and IL-17F antagonist, 320 mg for HS, researchers conducted two 48-week phase 3 trials BE HEARD I (n = 505) and II (n = 509), which enrolled patients with moderate to severe HS and a history of inadequate response to systemic antibiotics.
• Patients were randomly assigned to one of four groups: Bimekizumab every 2 weeks, bimekizumab every 2 weeks for 16 weeks followed by every 4 weeks of dosing, bimekizumab every 4 weeks, or placebo for 16 weeks followed by bimekizumab every 2 weeks.
• The primary outcome was an HS clinical response of at least 50% (HiSCR50) at week 16, defined as at least a 50% reduction in total abscess and inflammatory nodule count.

TAKEAWAY:

• A higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved an HiSCR50 response at week 16 in BE HEARD I (48% vs 29%; odds ratio [OR], 2.23; P = .006) and II (52% vs 32%; OR, 2.29; P = .0032) trials.
• Patients receiving bimekizumab every 4 weeks also achieved a higher HiSCR50 response at week 16 vs placebo in the BE HEARD II trial (54% vs 32%; OR, 2.42; P = .0038).
• At week 16, a higher proportion of patients receiving bimekizumab every 2 weeks vs placebo achieved at least a 75% HiSCR (HiSCR75) in both trials, and a higher proportion of those receiving bimekizumab every 4 weeks achieved HiSCR75 in the BE HEARD II trial.

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.”

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.

Dr. Sayed

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.”

Dr. Hsiao

• 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.

• 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.

TOPLINE:

Antiepileptic and anti-infectious agents were the most common drugs associated with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) in children in an analysis of a World Health Organization (WHO) database.

METHODOLOGY:

• SJS and TEN are rare, life-threatening mucocutaneous reactions mainly associated with medications, but large pharmacovigilance studies of drugs associated with SJS-TEN in the pediatric population are still lacking.
• Using the WHO’s pharmacovigilance database (VigiBase) containing individual case safety reports from January 1967 to July 2022, researchers identified 7342 adverse drug reaction reports of SJS-TEN in children (younger than 18 years; median age, 9 years) in all six continents. Median onset was 5 days, and 3.2% were fatal.
• They analyzed drugs reported as suspected treatments, and for each molecule, they performed a case–non-case study to assess a potential pharmacovigilance signal by computing the information component (IC).
• A positive IC value suggested more frequent reporting of a specific drug-adverse reaction pair. A positive IC025, a traditional threshold for statistical signal detection, is suggestive of a potential pharmacovigilance signal.

TAKEAWAY:

• Overall, 165 drugs were associated with a diagnosis of SJS-TEN; antiepileptic and anti-infectious drugs were the most common drug classes represented.
• The five most frequently reported drugs were carbamazepine (11.7%), lamotrigine (10.6%), sulfamethoxazole-trimethoprim (9%), acetaminophen (8.4%), and phenytoin (6.6%). The five drugs with the highest IC025 were lamotrigine, carbamazepine, phenobarbital, phenytoin, and nimesulide.
• All antiepileptics, many antibiotic families, dapsone, antiretroviral drugs, some antifungal drugs, and nonsteroidal anti-inflammatory drugs were identified in reports, with penicillins the most frequently reported antibiotic family and sulfonamides having the strongest pharmacovigilance signal.
• Vaccines were not associated with significant signals.

IN PRACTICE:

The study provides an update on “the spectrum of drugs potentially associated with SJS-TEN in the pediatric population,” the authors concluded, and “underlines the importance of reporting to pharmacovigilance the suspicion of this severe side effect of drugs with the most precise and detailed clinical description possible.”

SOURCE:

The study, led by Pauline Bataille, MD, of the Department of Pediatric Dermatology, Hôpital Necker-Enfants Malades, Paris City University, France, was published online in the Journal of the European Academy of Dermatology and Venereology.

LIMITATIONS:

Limitations include the possibility that some cases could have had an infectious or idiopathic cause not related to a drug and the lack of detailed clinical data in the database.

DISCLOSURES:

This study did not receive any funding. The authors declared no conflict of interest.

TOPLINE:

Cutaneous manifestations of cystic fibrosis (CF) include palmar wrinkling, nutrient deficiency dermatitis, vascular disorders, and reactions to CF treatments.

METHODOLOGY:

• Patients with CF, caused by a mutation in the CF Transmembrane Conductance Regulator (CFTR) gene, can develop diverse dermatologic manifestations.
• Researchers reviewed the literature and provided their own clinical experience regarding dermatologic manifestations of CF.
• They also reviewed the cutaneous side effects of CFTR modulators and antibiotics used to treat CF.

TAKEAWAY:

• Aquagenic wrinkling of the palm is common in individuals with CF, affecting up to 80% of patients (and 25% of CF gene carriers), and can be an early manifestation of CF. Treatments include topical medications (such as aluminum chloride, corticosteroids, and salicylic acid), botulinum toxin injections, and recently, CFTR-modulating treatments.
• CF nutrient deficiency dermatitis, often in a diaper distribution, usually appears in infancy and, before newborn screening was available, was sometimes the first sign of CF in some cases. It usually resolves with an adequate diet, pancreatic enzymes, and/or nutritional supplements. Zinc and essential fatty acid deficiencies can lead to acrodermatitis enteropathica–like symptoms and psoriasiform rashes, respectively.
• CF is also associated with vascular disorders, including cutaneous and, rarely, systemic vasculitis. Treatment includes topical and oral steroids and immune-modulating therapies.
• CFTR modulators, now the most common and highly effective treatment for CF, are associated with several skin reactions, which can be managed with treatments that include topical steroids and oral antihistamines. Frequent antibiotic treatment can also trigger skin reactions.

IN PRACTICE:

“Recognition and familiarity with dermatologic clinical manifestations of CF are important for multidisciplinary care” for patients with CF, the authors wrote, adding that “dermatology providers may play a significant role in the diagnosis and management of CF cutaneous comorbidities.”

TOPLINE:

A large international cohort study identified a higher risk for cardiovascular diseases and mortality in patients with prurigo nodularis (PN), particularly among women and White patients.

METHODOLOGY:

• Studies have shown increased risks for cardiovascular diseases in patients with PN, but limited sample sizes have hindered further subgroup analysis. Given PN’s pronounced sex and ethnicity skew, it is important to examine underrepresented groups to accurately assess their cardiovascular risk.
• In this propensity-score matched analysis, researchers identified 64,801 patients (59.44% women) with PN using electronic health reports from the Global Collaborative Network of TriNetX and matched to individuals without PN.
• Researchers calculated risks for 15 cardiovascular endpoints and all-cause mortality within 10 years of diagnosis. Major adverse cardiovascular events (MACE) included acute cerebral and myocardial infarction (MI), heart failure, ventricular arrhythmia, and sudden cardiac death.

TAKEAWAY:

• Patients with PN showed a higher risk for death (hazard ratio [HR], 1.1243) and MACE (HR, 1.117) (P < .0001 for both).
• PN was also associated with a higher risk for heart failure (HR, 1.062), thrombotic venous disease (HR, 1.26), angina pectoris (HR, 1.096), and peripheral arterial diseases (HR, 1.082) (P < .0001 for all) and for acute MI (HR, 1.11; P = .0015) and valve disorders (HR, 1.08; P = .0018).
• White patients with PN had a significantly increased risk for MACE, death, heart failure, cardiac arrest, vascular diseases, and acute MI, but this was not observed in people of color.
• Women exhibited a higher risk for MACE, heart failure, peripheral artery disease, acute MI, conduction disease, and valve disorders, while men did not have an increased risk for major or acute cardiovascular events. Both men and women had a higher risk for death, chronic ischemic heart disease, and venous disease.

IN PRACTICE:

“Although no novel PN-specific treatment rationale can be derived from the presented data, the potential risk of subsequent cardiovascular disease should be considered in the care of patients with PN, which includes screening and optimal management of other additional cardiovascular risk factors,” the authors wrote.

LIMITATIONS:

Retrospective observational design introduced inherent biases. Misdiagnosis or false coding in electronic health records could affect the data accuracy and ethnicity-specific analyses.
