The hallmark of<unk><unk>  is mesangial expansion. Nonetheless,<unk><unk>  is characterized by the presence of abnormalities in the glomeruli, such as glomerular hypertrophy, in the tubules and interstitium, such as tubular atrophy and interstitial fibrosis, and in the blood vessels, such as arteriosclerosis in both the afferent and the efferent renal arterioles. Findings on histopathological analysis may be evident very early in diabetes, but are often clinically present approximately 15 years after the onset of metabolic abnormalities.<unk><unk>  (DN) is characterized by the presence of proteinuria or decreased renal function in patients with diabetes mellitus.<unk><unk>  may be early or overt.
