ABSTRACT Moderate‐to‐severe hidradenitis suppurativa (HS) is a debilitating disease that often requires biological therapy. Despite the effectiveness of approved doses, some patients experience partial or loss of response over time, leading to the need for dose intensification. This retrospective multicentre study aimed to identify predictors of biological therapy intensification in HS patients. The results showed that prior use of biological treatments and biosimilar adalimumab were significant predictors of intensification, suggesting closer monitoring may be needed for certain patient profiles to optimise treatment outcomes.

Erythema nodosum leprosum (ENL) is a severe inflammatory complication of multibacillary leprosy with cutaneous and systemic involvement, usually occurring in a recurrent or chronic manner. Treatment of ENL is difficult and requires the use of systemic immunosuppressant with significant side effects, such as corticosteroids and thalidomide. [Extracted from the article]

Background: Bullous pemphigoid affects elderly individuals with multiple comorbidities, making conventional treatments unsuitable., Objective: Evaluate the effectiveness and safety of dupilumab in the treatment of bullous pemphigoid., Methods: A multicenter ambispective cohort study was conducted in 34 hospitals. Patients with bullous pemphigoid treated with Dupilumab were included. Most of patients (97.1%) received an initial 600 mg dose followed by 300 mg every two weeks., Outcomes and Measures: The primary outcome was the proportion of patients achieving complete remission within 4 weeks, defined as Investigator Global Assessment score of 0 or 1. Complete remission at weeks 16, 24, and 52, adverse events, reductions in peak pruritus numerical rating scale, and systemic glucocorticoid use were also assessed., Results: The study included 103 patients with a median age of 77.3 years, 58.0% male. Complete remission was achieved by 53.4% within 4 weeks and 95.7% by week 52. Peak pruritus scale reduced by 70.0% by week 4 and was completely controlled by week 24. Thirteen patients presented adverse events, most of which were mild. Systemic glucocorticoid use reduced by 82.1% by week 52. Shorter disease duration and exclusive cutaneous involvement predicted better response at 16 weeks. No differences in response rates to dupilumab were observed between drug-associated bullous pemphigoid and idiopathic cases. No significant difference in response rates was observed between patients treated with dupilumab in monotherapy and those receiving dupilumab with concomitant treatments., Conclusions: Dupilumab is effective, rapid, and safe in managing bullous pemphigoid, reducing the need for corticosteroids and other treatments. Early initiation and exclusive skin involvement predict better outcomes., (© The Author(s) 2024. Published by Oxford University Press on behalf of British Association of Dermatologists.
