Introduction: Ixekizumab proved to be effective and safe for psoriasis treatment in several randomized clinical trials and real‐life studies. Nevertheless, long‐term real‐world experiences are still lacking, with little data up to 4 years of treatment. Objectives: To analyse survival, effectiveness and safety of ixekizumab in a real‐life cohort of patients affected by moderate‐to‐severe psoriasis or psoriatic arthritis up to 260 weeks (5 years). Methods: We included all patients treated with ixekizumab from December 2017 to March 2021. Drug survival (DS) was analysed in patients at risk for up to 5 years. Cox analysis was adopted to evaluate possible predictive factors of discontinuation. Psoriasis Area Severity Index (meanPASI and PASI100, 90, and ≤3) was used as outcomes of effectiveness on observed patients at 16, 52, 104, 156, 208 and 260 weeks. Logistic regression was performed to identify possible predictive factors of response. Results: DS was 65.5% at 260 weeks, with being a super‐responder patient (achievement of PASI100 at 16 weeks and maintained at 28 weeks) correlated with less risk of discontinuation. PASI100, 90 and ≤3 was achieved by 54.1%, 60.5% and 73% of observed patients, respectively, at 16 weeks, and by 59.1%, 81.8% and 95.5%, respectively, at 260 weeks. High mean BMI was the only factor strongly associated with less achievement of the outcomes at the earlier time points: PASI100 at 16 weeks (OR 0.93, CI 0.87–0.98, p = 0.014) and at 104 weeks (OR 0.91, CI 0.84–0.98, p = 0.019), PASI90 achievement at 16 weeks (OR 0.94, CI 0.88–0.99, p = 0.028) and 104 weeks (OR 0.91, CI 0.83–0.99, p = 0.027), and PASI ≤3 (OR 0.86, CI 0.76–0.97, p = 0.018) at 104 weeks. No severe adverse events were observed. Conclusions: Ixekizumab showed high effectiveness and safety for up to 5 years, with survival of 2/3 of treated patients. Rapid response to treatment is predictive of long‐term response. [ABSTRACT FROM AUTHOR]

Background: Alcohol abuse is correlated with the onset and worsening of psoriasis, but its effects, as for smoking, on biological therapies are still poorly investigated., Materials and Methods: This study aimed to determine the prevalence of alcohol abuse and other discretionary habits (such as smoking and sedentary lifestyle) in patients with psoriasis treated with topicals, conventional systemic and biologic therapies. The second objective is to investigate the impact of discretionary habits, focusing on alcohol abuse, on the response to biological therapy. To identify alcohol dependence, the CAGE questionnaire was distributed among patients of our clinic., Results: 305 patients were included with 18% at high risk of alcohol abuse. Clinically, guttate psoriasis and psoriatic arthritis were more common in patients at higher risk of alcohol abuse. Furthermore, patients with an alcohol problem who started biological therapy reported a higher PASI than those who drank less. None of the considered variables seemed to correlate with discontinuation of medication or with lower achievement of the analyzed outcomes (PASI100, PASI90, and PASI≤3). There was a stronger association between alcohol dependence and patients receiving conventional therapy than with patients receiving biologics., Conclusions: The efficacy of biologicals did not seem to be impacted by alcohol consumption, smoking, or sedentary lifestyle., (© 2024 The Author(s).

Introduction: the selective IL-17 inhibitor secukinumab has demonstrated efficacy and safety in the treatment of moderate-severe psoriasis in recent years., Objective: evaluate effectiveness and drug survival (DS) of secukinumab in patients with psoriasis for up to 5 years., Methods: This is a retrospective study on a monocentric cohort of patients with psoriasis on secukinumab evaluating the achievement of PASI100, PASI90, and PASI ≤ 3 and DS analysis up to 260 weeks. DS multivariate analysis was carried out considering sex, age, age of onset of the disease, obesity, cardiovascular comorbidities, diabetes, involvement of difficult-to-treat sites, psoriatic arthritis, treatment-naïve status, and mean baseline PASI., Results: At baseline, we evaluated 255 patients on secukinumab. PASI100 was reached by 41.7% and 70.6% of patients at weeks 16 and 260, respectively. PASI90 showed a similar trend with 46.5% of patients achieving it at week 16 and 88.2% at week 260. Non-obese patients showed a faster response than patients with obesity in achieving PASI100, PASI90, and PASI ≤ 3, with significant differences at 28 weeks [55% vs. 40% ( p = 0.033), 64% vs. 49% ( p = 0.038), and 76% vs. 62% ( p = 0.036), respectively]. The estimated DS for secukinumab was 84.3% at 12 and 48% at 60 months. Obesity and smoking habits were associated with a higher risk of discontinuation in multivariate models (HR 1.6 CI 1.05-2.45, p = 0.028; HR 1.48 CI 1.01-2.17, p = 0.043, respectively)., Conclusions: Secukinumab showed effectiveness for up to 5 years of treatment, with a high DS and achievement of PASI100, PASI90, and PASI < 3 at these time points. Only obesity reduced the response and maintenance of DS.

Background: Brodalumab is a monoclonal antibody and IL-17 RA inhibitor that is approved for the treatment of moderate-to-severe psoriasis. The present study aims to estimate the drug survival (DS), effectiveness, and safety of brodalumab over a period of 156 weeks., Methods: The primary objectives were: (i) to determine the treatment response rate at Weeks 16, 28, 52, 78, 104, and 156 as defined by PASI100, PASI90, and an absolute PASI ≤ 3 and (ii) long-term DS. Secondary objectives included the evaluation of possible predictive factors associated with the achievement of response outcomes, and possible predictive factors associated with lower DS., Results: The treatment response was rapid, with 80.3% of patients achieving PASI ≤ 3, 66% PASI90, and 54.3% the complete clearance of disease at Week 16. The response improved at Week 28, when a plateau was achieved with mild loss of response at later time points, in particular for PASI100 and PASI90 in 55.2 and 65.5% of patients, respectively, at Week 156. After 156 weeks of treatment, 66.22% of patients were still on therapy, and the previous use of IL-17 inhibitors appeared to be associated with an increased risk of treatment discontinuation (HR: 2.51, CI: 1.06-5.98, P = 0.037), and achievement of PASI ≤ 3 until Week 16 with less risk (HR: 0.27 CI: 0.14-0.51, P < 0.001). Bio-naïve status was favorably associated with treatment response, while high BMI negatively affected the achievement of outcomes., Conclusion: Our study confirms the good effectiveness and favorable safety profile of brodalumab in a real-world setting for up to 3 years of treatment., (© 2024 the International Society of Dermatology.)

Purpose of the article: Baricitinib, a JAK 1/2 inhibitor, is approved for treating severe alopecia areata (AA). This study aimed to evaluate the long-term effectiveness and safety of baricitinib in a real-world setting over 52 weeks., Materials and methods: This multicenter retrospective study included 96 adult patients diagnosed with severe AA from 11 Italian Dermatology Units. All patients received 4 mg of baricitinib daily. Effectiveness was assessed using the Severity of Alopecia Tool (SALT) score, with the primary endpoint defined as achieving a SALT score ≤ 20 at week 52. Secondary endpoints included achieving a Clinician-Reported Outcome (ClinRO) score of 0 or 1 for eyebrow (ClinRO EB) and eyelash hair loss (ClinRO EL), with a ≥ 2-point improvement from baseline., Results: After 52 weeks, 61.5% of patients achieved a SALT score ≤ 20. Additionally, 67.6% and 69.7% of patients attained ClinRO EB and ClinRO EL scores of 0 or 1, respectively, with a ≥ 2-point improvement. No significant adverse safety events were reported during the study., Conclusions: The study confirms the long-term effectiveness and safety of baricitinib for severe AA in a real-world setting. These findings align with clinical trial results and reinforce baricitinib's role as a viable treatment option for severe AA.
