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.

It is necessary to identify which factors or comorbidities are associated with more severe hidradenitis suppurativa, aiming to identify which patients may benefit more from early systemic treatment or a more aggressive approach. A retrospective study was conducted, including patients diagnosed with HS at the dermatology department of a Spanish hospital over a 5-year period. A total of 322 patients were included. A relationship was found between diagnostic delay, the presence of acne conglobata, pilonidal sinus, cardiovascular risk factors (hypertension, dyslipidemia, and/or diabetes mellitus) and more severe HS. No significant relationship was found between psychiatric comorbidities and the severity of the HS. The presence of perianal or truncal involvement was significantly associated with severe HS. Female sex and the presence of a family history of HS were associated with an earlier onset of the disease., (Copyright © 2024 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background: Bullous pemphigoid (BP) is the most common autoimmune blistering disease. Most patients are older and have associated multiple comorbidities. Topical and systemic corticosteroids are considered the first-line treatment for BP, and immunosuppressants are used as steroid-sparing treatments. However, both have side-effects and contraindications, which are even more common in this older population. New treatments targeting interleukins and receptors related to BP pathogenesis have been proposed to decrease these side-effects while achieving equal or better effectiveness and response rates. Omalizumab is a monoclonal antibody that targets IgE and has been proposed for the treatment of BP due to the evidence that IgE autoantibodies play an essential role in BP pathogenesis., Objectives: To assess the efficacy and safety of omalizumab for the treatment of BP., Methods: We carried out a multicentre, retrospective, observational study including patients diagnosed with BP who received omalizumab for ≥ 3 months from 15 tertiary hospitals in Spain. IgE levels prior to treatment were measured, and we evaluated the possible correlation with clinical response. We excluded patients treated with omalizumab for < 3 months, as we consider this duration to be insufficient for a comprehensive assessment of its efficacy. To evaluate the effectiveness of the treatment, we used the percentage of body surface area improvement., Results: We included 36 patients. The vast majority had associated multiple comorbidities, and all patients had used other systemic therapies apart from corticosteroids before omalizumab. In total, 83% experienced some kind of treatment response and 42% of all patients treated achieved complete response. We did not find any correlation between higher IgE levels and a better response (P = 0.2). All patients tolerated omalizumab without reported side-effects., Conclusions: Omalizumab is a good therapeutic alternative for BP as it provided clinical response in most patients, and nearly one-half of the cases achieved complete response. It showed no side-effects, which is crucial in older patients with BP., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (© The Author(s) 2024.

Tildrakizumab is an IL-23-inhibitor that has been approved to treat plaque psoriasis. However, few reports have become available on its efficacy profile in the real-world. Our objective was to study the mid-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the Spanish routine clinical practice setting. This was a retrospective multicenter study that included a total of 91 psoriatic patients on tildrakizumab. The mean Psoriasis Area and Severity Index (PASI) was 9.09 (SD, 5.30). The overall tildrakizumab survival rate was 93.47% for a mean treatment exposure of 30.18 weeks (SD, 16.57). No drug discontinuation was associated with drug tolerability, or adverse reactions. Absolute PASI ≤3 was reached by 91.3% and 96.5% of the patients on weeks 28 and 52, respectively. Response was not impacted by weight, age (>65), metabolic syndrome, presence of arthritis, or previous number of biological therapies used. Based on our own experience tildrakizumab is an effective strategy to treat plaque psoriasis and difficult-to-treat-areas., (Copyright © 2024 AEDV. Publicado por Elsevier España, S.L.U.

This was an observational and retrospective multicentre study conducted on adolescents and adults diagnosed with moderate-to-severe atopic dermatitis (AD) and treated with upadacitinib. Disease severity was measured by Eczema Area and Severity Index (EASI), validated investigator global assessment for AD and pruritus Numerical Rating Scale (NRS) at baseline and Weeks 4, 16, 24 and 52 (when available). Twenty-one patients were included. All patients had previously received topical and systemic corticosteroids. Rapid response to upadacitinib was observed: Mean (SD) EASI score was 19.8 (6.5) at baseline, and 3.1 (4.2), 0.9 (1.4), 0.6 (0.6) and 0.6 (0.6) at the Weeks 4, 16, 24 and 52, respectively. Itch was controlled at Week 4 in all patients (mean [SD] NRS score 7.6 [1.9] baseline, 1.5 [1.3] W4). Severe infections or major adverse cardiovascular events were not reported. We highlight effectiveness and rapid response of upadacitinib in achieving itch control even in long-standing recalcitrant cases., (© 2023 Australasian College of Dermatologists.)

Hidradenitis suppurativa (HS) is a chronic, inflammatory, and recalcitrant skin disease of the terminal hair follicle. Therapeutic alternatives in HS are limited nowadays. Adalimumab, is the only approved biological treatment for patients with moderate to severe HS, and some patients do not reach an optimal response, or experience a progressive response loss, needing therapeutic alternatives. IL-23 pathway is also involved in HS pathogenesis, so its blockade could contribute to reach disease control. Guselkumab is a monoclonal antibody targeting the p19 subunit of extracellular IL-23, currently approved for psoriasis in adults, and recently some authors have reported its effectiveness in patients with moderate to severe HS refractory to other systemic treatments, becoming a hope for some patients. However adequate dosing and intervals have not been determined yet, so in most published series, doses approved for psoriasis are commonly used. On this topic a retrospective bicentric study including HS patients treated with guselkumab in the dermatologic departments of university hospitals Puerta de Hierro of Majadahonda (Madrid, Spain) and Doctor Peset of Valencia (Valencia, Spain) was conducted. We reported effectiveness, dosage and frequency of administration in the cohort, in order to establish the most effective dosage regimen and to clarify the potential role of guselkumab for this disease., (© 2022 Wiley Periodicals LLC.)
