AntiTNF-alpha therapy normalizes levels of lipids and adipokines in psoriatic patients in the real-life settings

Abstract

Abstract Studies have shown that the levels of pro-inflammatory adipokines in patients with psoriasis are higher than in general population. 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 mean serum concentrations of adiponectin in patients from adalimumab, etanercept and infliximab group were similar to control group (p > 0.05, 142.71, 164.32, 129.35 and 174.44 μg/ml respectively). Resistin levels were higher in patients (p < 0.05, 4.48, 4.53 and 3.39 ng/ml respectively) than in controls (3.05 ng/ml). Mean leptin concentrations were significantly higher (p < 0.05) in the study group than in subjects without psoriasis (428.61, 523.24, 755.27 and 154.10 pg/ml respectively). A significant decrease in the mean resistin concentration was observed under the influence of biological therapy (p < 0.05). Decrease in serum leptin level was noted in etanercept and infliximab groups (p = 0.001 and p = 0.002 respectively). Improvement in all lipidogram parameters was noted in all examined groups (p < 0.05). Results may prove that biologic therapy affects the systemic inflammation associated with psoriasis and this effect persists with long-term therapy.
