Psoriasis is a chronic, recurrent, inflammatory disease. The incidence of this disease is increasing year by year, seriously affecting people's quality of life. Biologic agents have the advantages of rapid and efficient treatment of moderate and severe psoriasis, but their safety and recurrence are still seriously affect the application. Traditional Chinese medicine treatment of psoriasis has the advantages of fewer adverse reactions, low recurrence rate and improvement of patients' systemic symptoms while exerting the curative effect. The prevention and treatment of psoriasis by combining traditional Chinese and Western medicine has become the academic consensus. The sequential treatment of psoriasis with biological agents combined with Traditional Chinese medicine has a better therapeutic effect than that of single therapy. At present, the sequential treatment of psoriasis with targeted biological agents combined with traditional Chinese medicine has not been reported in the literature, and there is a lack of high-level clinical evidence to support it. Therefore, this project aims to provide evidence support for the clinical efficacy and safety of sequential treatment of psoriasis by traditional Chinese and Western medicine through a multi-center, randomized, double-blind, placebo-controlled trial.
The purpose of this study is to objectively and standardly evaluate the clinical efficacy and safety of sequential treatment of psoriasis with traditional Chinese and Western medicine through a multi-center, randomized, double-blind, placebo-controlled trial.
