Abstract
AIMS To evaluate glucose tolerance of patients with Vogt–Koyanagi–Harada (VKH) disease before systemic corticosteroid therapy, and to assess changes brought on by treatment.
METHODS 20 VKH patients with acute bilateral panuveitis were studied. 20 healthy adults and 11 Behçet’s disease patients with active uveoretinitis served as controls. A 75 g oral glucose tolerance test (OGTT) was given in the acute stage of ocular inflammation before systemic corticosteroid therapy. The OGTT was repeated in the convalescent stage of VKH disease in the patients with glucose intolerance before treatment. Insulin response was examined at the same time as the OGTT when possible.
RESULTS 55% of VKH patients (11/20) showed glucose intolerance but no apparent insulin secretion deficiency was detected. Four of seven patients in the convalescent stage showed improvement of glucose tolerance. None of the normal controls or disease controls showed glucose intolerance.
CONCLUSION A high incidence of glucose intolerance was found in the acute stage of VKH disease. However, glucose intolerance improved in most cases after systemic corticosteroid therapy. It is possible that glucose intolerance seen in VKH patients may be related to the autoimmune inflammatory process of this disease.
