Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants Achieving a Greater Than or Equal to 75 Percentage Improvement From Baseline in Psoriasis Area and Severity Index (PASI 75) Score at Week 12 [ Time Frame: Baseline and Week 12 ]

    Number of participants achieving greater than or equal to 75 percentage improvement from baseline in Psoriasis Area and Severity Index (PASI) at Week 12. PASI is the widely used tool for the measurement of severity of psoriasis. This is a test of how bad a person's psoriasis is. The combination of redness, scaling, and thickness, as well as overall body involvement determine the PASI score. The scale ranges from 0 (best) -72 (worst). Baseline visit refers to Week 0.

    baseline, Week 12

Secondary Outcomes (5)

  • improvement of dermatology quality of life: Dermatology Life Quality Index

    baseline, Week 12

  • The effect of metformin on glucose and insulin metabolism as assessed by serum marker, HOMA index

    baseline, Week 12

  • Number of Participants Achieving a Greater Than or Equal to 90 Percentage Improvement From Baseline in Psoriasis Area and Severity Index (PASI 90) Score at Week 12

    baseline, Week 12

  • The effect of metformin on glucose and insulin metabolism as assessed by clinical marker, weight (kg)

    baseline, Week 12

  • The effect of metformin on gut-microbiota profile of pre- and post-metformin samples

    baseline, Week 12

Study Arms (2)

Metformin

EXPERIMENTAL

the distributed subjects will be orally administered Metformin 500mg bid lasting for 12 weeks.

Drug: Metformin

Placebo

PLACEBO COMPARATOR

the distributed subjects will be orally administered Metformin-like placebo 500mg bid lasting for 12 weeks.

Drug: Metformin

Interventions

An intervention of either metformin or placebo 500mg twice daily plus standard care for 12 weeks. Besides Metformin, standardized topical treatment is given to all patients; For severe psoriasis patients(PASI\>8), Methotrexate will be treated orally 7.5mg every week for both the intervention group and the placebo group as a systemic standard care.
