The aim of the study was to investigate the influence of 36-month therapy with TNF-α inhibitors (adalimumab, etanercept, infliximab) on the levels of adipokines (resistin, adiponectin, leptin) and lipids (TG, cholesterol, LDL, HDL) in 37 psoriasis patients and 30 healthy controls. The gene discussed is TNF; the disease is psoriasis.
