Psoriasis treatment with adalimumab in clinical practice: long-term experience in a center for biological therapy in the Czech Republic

Abstract

Background: Adalimumab therapy has an established record of high efficacy in psoriasis treatment. However, only a limited number of studies have investigated long-term results in clinical practice.Objectives: To evaluate the effectiveness and safety of adalimumab in a center for biological therapy in the Czech Republic.Methods: Retrospectively, we analyzed 90 patients with moderate to severe psoriasis who were treated with adalimumab between 2008 and 2016. The proportion of patients achieving PASI75, 90, and 100 after 3, 6, 12, 18, 24, 30, and 36 months was determined.Results: The mean period of treatment was 4.4 years (maximum duration reached was 8.6 years). PASI75 was observed in 85.6% of patients after 3 months, PASI90 in 50%, and PASI100 in 23.3%. Throughout the 3-year analysis, PASI90 was persistent in 91.4% and PASI100 in 51.7%. The majority of patients who reached PASI100 showed a trend to maintain the response in the long-term follow-up. No safety issues were identified.Conclusions: Adalimumab is effective and safe in the long-term treatment of psoriatic patients in daily clinical practice. Once patients achieved PASI100, they tended to remain stable in treatment.
