Secukinumab demonstrates improvements in absolute and relative psoriasis area severity indices in moderate-to-severe plaque psoriasis: results from a European, multicentric, retrospective, real-world study.

Objective: This European, multicentric, retrospective study aimed to collect data on secukinumab effectiveness in a real-world setting.Research design and methods: All psoriatic patients starting secukinumab between January 2016 and February 2017 in 11 European centers were followed until February 2018 and retrospectively evaluated.Main outcome measures: Secukinumab effectiveness was assessed by relative improvement from baseline of the Psoriasis Area Severity Index (PASI) and absolute PASI score modifications throughout 52 weeks of therapy. Additionally measures assessing effectiveness were used, including improvements of body surface area (BSA) and Dermatology Life Quality Index (DLQI).Results: Out of the 330 patients with potentially 52-week treatment duration, naïve to biologics patients showed greater probability to achieve PASI score of ≤1, ≤2, ≤3, and ≤5 at week 12, compared to bio-experienced patients (45.86% vs. 27.17%, 62.42% vs. 42.42%, 73.89% vs. 57.80%, and 84.08% vs. 74.57%, respectively). The greater effectiveness of secukinumab treatment in bio-naïve patients was confirmed at week 24 and 52.Conclusions: In this real-world experience, secukinumab was proven effective in treating psoriasis patients throughout a 52-weeks observation period, with higher response in bio-naïve patients. This study may contribute to defining the clinical profile of secukinumab best-responders.

Moderate-to-severe psoriasis and pregnancy: impact on fertility, pregnancy outcome and treatment perspectives.

Psoriasis affects 2-4% of the world's population, with no difference between men and women and 70% of patients experiencing disease onset before the age of 40, which coincides with the reproductive years. Few data are available from literature on impact of psoriasis on fertility, course and outcome of pregnancy and risk associated with treatments. Recent studies on other immune-mediated inflammatory diseases, among which psoriasis is also included, indicate that rheumatoid arthritis and inflammatory bowel diseases can impact female fertility and pregnancy outcomes especially during active disease episodes. In psoriasis hormonal and metabolic comorbidities, unhealthy lifestyles and systemic inflammation could also influence the ability to conceive, pregnancy course and birth outcomes. In this article we review current knowledge on reproductive function, course and outcome of pregnancy in women affected by moderate-to-severe psoriasis. Systemic treatments are also considered with a special focus on TNF-alpha blocking agents and implication of molecular structure on placental transportation and fetal exposure.
