Rapid response of nail psoriasis to secukinumab in patients with moderate to severe psoriasis after 12 weeks of treatment with a total of 24 weeks of follow‐up

Abstract

AbstractBackground/ObjectivesNail psoriasis, a subtype of psoriasis, can cause significant pain, disability, and reduced quality of life. Despite the established efficacy of anti‐IL17 secukinumab in improving skin psoriasis, there is a lack of clinical trials focusing on nail psoriasis as primary endpoint. This study aims to investigate the efficacy of secukinumab in treating nail psoriasis in patients with moderate to severe psoriasis.MethodsWe prospectively recruited patients newly diagnosed with moderate to severe psoriasis in single centre from January 2021 to January 2022 who were treated with secukinumab.ResultsA total of 16 patients consisting of 9 males and 7 females were included. Their mean age was 38.88 ± 10.29 years. They had an average initial Nail Psoriasis Severity Index (NAPSI) score of 45.06 ± 20.39 and an average NAPSI score at 12 weeks of 8.94 ± 13.50, showing a significant (p < 0.05) decrease of NAPSI score after 12 weeks of secukinumab treatment. After 24 weeks of treatment, NAPSI score was decreased to 5.12 ± 8.52.ConclusionSecukinumab rapidly improved nail psoriasis after 12 weeks of treatment, with further enhancement at 24 weeks, suggesting its potential as a potent therapeutic option for nail psoriasis.
