Comprehensive Intervention of Diabetes and Psoriasis Comorbidity Prevention and Control

We will recruit 300 patients with psoriasis from Yueyang Hospital of Integrative Medicine, Shanghai University of Traditional Chinese Medicine, who will not be currently diagnosed with diabetes but will have been identified as high-risk individuals based on the developed risk assessment model. Based on doctor's treatment opinions and patient preferences, participants will be divided into two groups in a 1:1 ratio: a Western medicine group and a TCM comprehensive treatment group.

Patients in the Western medicine group will receive treatment according to guidelines. Patients in the TCM comprehensive treatment group will be treated according to the guidelines and will additionally receive Taodan granules (to be taken daily during the treatment period after brewing the granules with lukewarm water in the morning and evening) and fish oil (1g, taken orally twice daily).

Patients in the TCM comprehensive treatment group will be required to complete at least 150 minutes of moderate-intensity aerobic exercise per week under the supervision of a physician. The patients will be treated for 16 weeks and followed up for 24 weeks to see if the treatment prevents the development of diabetes or insulin resistance.
