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.

BACKGROUND/OBJECTIVES: Nail 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. METHODS: We prospectively recruited patients newly diagnosed with moderate to severe psoriasis in single centre from January 2021 to January 2022 who were treated with secukinumab. RESULTS: A 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. CONCLUSION: Secukinumab 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.

Hormone Replacement Therapy and Psoriasis Risk: A Nationwide Population-Based Cohort Study.

BACKGROUND: Hormone replacement therapy (HRT) is used to relieve menopause symptoms, but has been reported to be associated with coronary heart disease and cancers in women. However, a link between HRT and psoriasis has yet to be established. The aim of this study was to determine the association between HRT and the risk of psoriasis. METHODS: We executed a nationwide population-based study. A total of 1,130,741 post-menopause women were enrolled in the national health care insurance database based on the enrollment criteria. The study population was classified into four groups based on the duration of the HRT, and the risk of psoriasis was analyzed. RESULTS: The incidence rates of psoriasis per 1,000 person-years were 3.36 and 4.09 in the no history of HRT and ≥ 5 years of HRT, respectively. After adjustment for age, smoking, alcohol intake, regular exercise, body mass index, diabetes mellitus, hypertension, and dyslipidemia, the most prolonged duration of the HRT group (≥ 5 years) exhibited significantly increased risk of developing psoriasis (hazard ratio, 1.22; 95% confidence interval, 1.16-1.29). CONCLUSION: We propose that HRT in post-menopausal women is associated with an increased likelihood of psoriasis development.
