Serum concentration of the soluble interleukin-2 receptor in vitiligo patients.

Abstract:

:Serum levels of sIL-2R can be used to monitor in vivo immune activation and its elevation have been shown to be correlated with T cell mediated immune disease such as atopic dermatitis, psoriasis, lymphoma and systemic sclerosis. Vitiligo is the disease of depigmentation caused by destruction of melanocytes, and there have been extensive studies on the immune pathogenesis. If the pathogenesis of vitiligo is correlated with the activation of T lymphocytes, the change of IL-2R will be detected compared with that of normal control. Therefore we sought the change in sIL-2R to determine whether T lymphocytes from patients with vitiligo show abnormal biological behavior. The quantitation of sIL-2R was done by sandwich enzyme-linked immunosorbent assay (ELISA) from the sera of 79 vitiligo patients and 40 normal controls. The results were summarized as following. The sIL-2R level in vitiligo patients (671.91 +/- 368.59 U/ml) was significantly increased compared with that of controls (370.8 +/- 71.8 U/ml; P < 0.005). According to clinical types, sIL-2R level in focal type of vitiligo patients was significantly higher than those in other types (segmental or generalized; P < 0.05). The sIL-2R level in patients less than 1 year duration was significantly higher than in patients more than 1 year duration (P < 0.05). The sIL-2R levels were not significantly different between active and inactive group. There was no significant differences among sIL-2R levels according to sex or age of onset. Our study showed that sIL-2R level was higher in vitiligo patients compared with that of normal controls, so the activation of T lymphocytes would be an important component in the pathogenesis of vitiligo. The higher sIL-2R levels in recent onset group would suggest that sIL-2R level might be an acute immunologic marker in vitiligo patients.
