Vitiligo and Juvenile Diabetes Mellitus

Five juvenile diabetics had vitiligo. In two children, the vitiligo preceded the onset of diabetes. Four of the five patients had thyroid, adrenal, or gastric antibodies or a combination of these. In three children HLA-B8 antigens were detected, and one additional patient had HLA-Bw15. Of eight nondiabetic children with vitiligo, one had abnormal glucose tolerance. To the evidence supporting an autoimmune form of diabetes mellitus we add another observation: the association of insulin-dependent diabetes and childhood vitiligo.
