Glucose tolerance studies in lichen planus.

A study of glucose tolerance and insulin response to oral glucose was carried out in 56 consecutive histologically confirmed cases of lichen planus. 30.3% patients showed abnormal glucose tolerance. The pattern of insulin response was similar to that seen in type II diabetes. Insulin/glucose ratio showed the same relationship as seen in type II diabetes. These results reinforce the possibility of glucose intolerance in lichen planus patients. However, no correlation between glucose tolerance abnormalities and duration and distribution of lesions was observed.
