Diabetic glomerulosclerosis without overt diabetes mellitus.

The duration of diabetes mellitus and the presence of hyperglycaemia were thought to be important in the development of nodular glomerulosclerosis. We report on 3 patients without overt diabetes, but with glucose intolerance, all male, aged 43-66 years, with histological features of diabetic glomerulosclerosis. The nodular form was present in 2 patients and the diffuse form in 1. These cases suggest that factor(s) other than hyperglycaemia are responsible for diabetic renal damage.
