Metformin for Treatment of Psoriasis Combined With Disorders of Glucose and Lipid Metabolism

Summary

Psoriasis and metabolic disorders are well-known mutual comorbidities. The investigators hypothesized metformin can ameliorate both psoriasis and metabolic disorders mainly via gut microbiota modulation. The investigators design a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of treatment of metformin for psoriasis combined with disorders of glucose and lipid metabolism and to explore the role of gut microbiota during the process.
