Diffuse diabetic glomerulosclerosis in a patient with impaired glucose tolerance: report on a patient who later develops diabetes mellitus.

Diabetic glomerulosclerosis might be seen in diabetics but its presence in patients with impaired glucose tolerance is quite rare. A 31-year-old woman who was admitted to our department was diagnosed with hypertension, nephrotic syndrome and impaired glucose tolerance. Her renal biopsy was compatible with diabetic glomerulosclerosis. She developed overt diabetes mellitus (DM) after one year of impaired glucose tolerance. Hypertension might have accelerated the progression of diabetic nephropathy.
