Current approach in the prevention and treatment of diabetic nephropathy

: Diabetic renal microangiopathy accounts for enormous morbidity and mortality, particularly in patients who develop diabetes in childhood or early youth; in the last few years its pathogenesis has been therefore extensively studied, aiming to prevent renal complications or at least of slowing down its progression toward uremia. Though not always in accordance with theoretical expectations, the results of clinical trials have nevertheless widened our therapeutic possibilities; in fact, besides the attainment of an optimal metabolic control, other possible interventions include a careful correction of albeit minimal elevations in arterial pressure; the interference with intrarenal hemodynamic parameters; the correction of insulin-independent metabolic pathways, abnormally activated in the diabetic, such as non enzymatic glycation and polyol pathway; the treatment of endothelial and platelet alterations; the improvement of the rheologic properties of blood.
