In the current meta analysis we compared the levels of adipokines (adiponectin, omentin, chemerin, visfatin, lipocalin-2 and resistin), circulating cytokines (TNF-α, IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, IL-18, IL-21, IL-22 and IL-23) and other inflammatory molecules (sE-selectin, fibrinogen, C3) between psoriasis patients and healthy individuals. This evidence concerns the gene IL6 and psoriasis.
