Measurement of interleukin-17 and transforming growth factor-β in patients with vitiligo / 中华皮肤科杂志

ABSTRACT

ObjectiveTo assess the relationship of interleukin-17(IL-17) and transforming growth factor-β(TGF-β) with the development of vitiligo.MethodsEnzyme-linked immunosorbent assay (ELISA) was carried out to measure the levels of IL-17 and TGF-β in sera from 120 patients with vitiligo and 60 healthy controls.The correlations of serum IL-17 and TGF-β levels with patients' gender,stage and duration of disease,involved body area and presence of family history were assessed.ResultsThe level of serum IL-17 was significantly higher in patients with active vitiligo than in the controls and patients with stable vitiligo (both P ＜0.05).With the rise in involved body area,the level of serum IL-17 gradually increased (x2 =12.656,P ＜0.05).The level of TGF-β in patients with active vitiligo was a little higher than that in the controls and patients with stable vitiligo,with no significant difference between these groups(both P ＞ 0.05).Conclusions The levels of serum IL-17 and TGF-β are somewhat correlated with the activity of vitiligo,and both of them may play a certain role in the pathogenesis of vitiligo.
