Effectiveness of risankizumab in the treatment of palmoplantar psoriasis: a 52-week Italian real-life experience

Abstract

Background: Data on the treatment of palmoplantar psoriasis (PP) are scarce, representing a therapeutic challenge. This study aims to assess the efficacy and safety of risankizumab in a population of patients with psoriasis with a palmoplantar involvement, over a 52- week treatment period.

Methods: We performed a retrospective analysis in a cohort of patients with PP, with or without involvement of other skin sites. Palmoplantar Psoriasis Area and Severity Index (ppPASI) was assessed at baseline and after 4, 16, 28 and 52 weeks, to evaluate the PP severity.

Results: Sixteen patients were enrolled. The rates of ppPASI90 responses constantly increased during the period of observation and were 18.7%, 62.2%, 75.0% and 81.2% at weeks 4, 16, 28 and 52, respectively. Only two patients suspended treatment because of ineffectiveness at week 16.

Conclusion: Our data from a series of 16 patients reveal that risankizumab could represent an effective and safe therapeutic choice in patients with PP.
