Glucose tolerance in patients with oral lichen planus

Of 123 patients with oral lichen planus two were known diabetics. The remainder were tested for fasting glucosuria, 113 for fasting blood glucose and 103 also with an oral glucose tolerance test. According to the criteria of WHO, 18 of the 123 patients were diabetics. In most of these patients the oral glucose tolerance test was only slightly abnormal. No decrease of the glucose tolerance with increasing duration of lichen planus was demonstrable. Comparison with two general population studies did not reveal any significant difference between the glucose tolerance of the lichen planus patients and that of the general population samples.
