Overexpression of IL-6 has been implicated in the pathology of numerous autoimmune and chronic inflammatory diseases, including psoriasis, and relative deficiency of IL-10 in psoriatic patients seems to be important in the development of this disease. The aim of this study was to investigate the association between IL-6 and IL-10 single nucleotide polymorphisms and susceptibility to psoriasis vulgaris. DNA from 78 patients with psoriasis vulgaris and 74 healthy volunteers was investigated. IL-6 promoter gene single nucleotide polymorphisms in position –174, and IL-10 single nucleotide polymorphisms in positions –1082, –819 and –592 were evaluated by polymerase chain reaction using sequence-specific primers. No significant differences were found in the polymorphisms of IL-6 and IL-10 promoter genes between patients with psoriasis and healthy controls.
