Background: Dupilumab, a fully human monoclonal antibody targeting the alpha subunit of IL-4 was recently approved for the treatment of moderate-to-severe atopic dermatitis (AD) in adult patients. Objective: To assess dupilumab effectiveness and safety in adults with moderate-to-severe AD in a real-life Italian multicentre retrospective cohort. Methods: Adult moderate-to-severe AD patients, referring to 39 Italian centers, received dupilumab in the context of a national patient access program. Disease assessment was performed at baseline, after 4 and 16 weeks of treatment using Eczema-Area-and-Severity-Index (EASI) score, itch and sleep numerical-rating-score (itch-NRS, sleep-NRS) and Dermatology-Life-Quality-Index (DLQI). Results: A total of 109 (71 M/38F) patients was studied. There was a significant reduction in EASI score, itch-NRS, sleep-NRS and DLQI from baseline to week 4 and a further significant decline to week 16. EASI 50, EASI75 and EASI90 were achieved by 59.6%, 28.4% and 9.3% of patients at 4 weeks and by 87.2%, 60.6% and 32.4% of them at 16 weeks, respectively. Adverse events were experienced by 19.2% (21/109) of the patients and they were all mild in intensity, being conjunctivitis the most common side effect. Conclusions: Dupilumab significantly improved disease severity, pruritus, sleep loss and quality of life with an acceptable safety profile.

Background: In elderly patients the management of psoriasis is challenging due to contraindications and a higher risk of side effects. Objective: Our retrospective study aimed to evaluate the long-term efficacy and safety profile of subcutaneous anti-tumor necrosis factor (anti-TNF) agents in elderly psoriatic patients. Methods: The study included 89 patients (aged ≥65 years) with plaque-type psoriasis and psoriatic arthritis treated with the subcutaneous anti-TNF-α agents etanercept or adalimumab as monotherapy for a long-term continuous period. Results: Efficacy results were consistent and stable over long-term observation, as expressed by mean Psoriasis Area and Severity Index (PASI) score variation, percentage of patients achieving PASI50 and PASI75 and by the improvement of articular indices, pain visual analogue scale (Pain-VAS) and 44-Joint Disease Activity Score (DAS44-ESR). The proportion of patients achieving PASI50 was 91.80 and 82.14% at week 156 with etanercept and adalimumab treatment, respectively, while the proportion of patients achieving PASI75 was 83.61 and 71.43% at week 156 when treated with etanercept and adalimumab, respectively. The mean DAS44-ESR score decreased from 5.80 to 0.89 and from 3.43 to 1.44 at week 156 and the mean Pain-VAS score decreased from 75.10 to 3.15 and from 71.30 to 18.26 at week 156 with etanercept and adalimumab treatment, respectively. Both treatment adherence and safety profile were good. Conclusions: Our study demonstrates that subcutaneous anti-TNF-α agents are appropriate in the long-term management of elderly patients.

A relationship between psoriasis, pro-inflammatory cytokines and obesity has been demonstrated. Tumour necrosis factor-alpha (TNF-α), that is involved in the pathogenesis of psoriasis, is commonly over-expressed in obese subjects, and seems to be derived from inflammatory cells and adipocytes. The primary aim of this study is to investigate whether the Body Mass Index (BMI) of patients influences the clinical response to etanercept, a competitive inhibitor of TNF-α approved for the treatment of moderate-to-severe plaque-type psoriasis. The secondary aim is to evaluate whether the TNF-α inhibition influences the weight and BMI profile of patients. One hundred patients received 50 mg etanercept twice weekly for 12 weeks, followed by 25 mg. At weeks-12 and 24, treatment efficacy and tolerability were evaluated, as well as body weight and BMI. BMI values did not correlate with etanercept efficacy. Mean PASI score variation did not show significant differences among the BMI groups. A statistically significant weight gain and BMI variation were observed in a consistent rate of patients. Patient BMI does not influence psoriasis efficacy parameters. Although the role of and TNF-α molecules on weight regulation need to be confirmed, our study shows that etanercept treatment may induce weight gain and a BMI increase.
