Abstract
Background
Plaque psoriasis is a chronic, recurrent, immune-mediated inflammatory skin disease. This study aimed to investigate effectiveness of interleukin (IL)-17A inhibitor treatment and effectiveness after treatment interruption in plaque psoriasis patients and analyze the related factors.
Methods
This study retrospectively collected clinical characteristics and related treatment status of plaque psoriasis patients treated with IL-17A inhibitors, and evaluated the treatment effectiveness, reasons for treatment interruption, effectiveness after treatment interruption, and risk factors affecting treatment effectiveness.
Results
This study ultimately included 106 patients with plaque psoriasis, including 61 males (57.55%) and 45 females (42.45%), aged 41.0 (31.0-54.0) years and with a disease duration of 12.0 (8.0-20.0) months. Among them, 71 cases (67%) achieved PASI90 after receiving IL-17A inhibitor treatment, and 35 cases (33.02%) achieved PASI75. A total of 50 patients (50/106, 47.17%) interrupted treatment, 23 patients (23/50, 46%) maintained a therapeutic effect of PASI90 or above, and 27 patients (27/50, 54%) had a therapeutic effect lower than PASI75, with median time of treatment interruption of 1.0 (1.0-3.5) months. Univariate analysis findings showed that duration of IL-17A inhibitor treatment interruption and reasons for interruption had significant statistical significance on treatment effectiveness (all P<0.05). In multivariate analysis, treatment interruption (OR=7.154, 95% CI: 2.528-20.24) and reasons such as stress/anxiety (OR: 14.889, 95% CI: 1.160-23.480) were risk factors affecting treatment effectiveness.
Conclusion
Interleukin (IL)-17A inhibitor treatment interruption plays critical effects on the treatment of plaque psoriasis. Early and long-term adherence to IL-17A inhibitor treatment can control the course of the disease and improve the long-term health of psoriasis patients.
