Renal complications in non-insulin-dependent diabetes mellitus.

Renal failure among elderly individuals with diabetes is a substantial clinical and public health problem. These individuals account for the majority of renal failure among people with diabetes mellitus in the United States. Although limited population-based data directly provide evidence regarding the incidence of and risk factors for ESRD, extant data suggest that blacks and Pima Indians have a markedly increased risk of ESRD compared with whites in the United States. Proteinuria and microalbuminuria appear to be extremely common in elderly individuals with NIDDM and are strongly associated with overall survival, cardiovascular morbidity and mortality, and the development of ESRD. Although randomized clinical trials are needed to test intervention strategies to reduce morbidity and mortality associated with renal disease among individuals with NIDDM, extant data suggest that management efforts directed at hypertension control and, possibly, moderate restriction of protein intake may be important therapeutic modalities for prevention of renal disease and its associated sequelae among elderly individuals with diabetes.
