Pathological Definition and Evaluation of Diabetic Neuropathy and Clinical Correlations

     Anders A.F. Sima

Abstract:   Diabetic neuropathy is a major complication of diabetes mellitus affecting to an equal extent type 1 and type 2 patients. Various mechanisms including metabolic and vascular abnormalities have been proposed to explain the progressive pathological changes that occur in peripheral nerve. Regardless of the precise mechanisms, structural abnormalities lead to functional changes which eventually result in the clinical manifestations of diabetic neuropathy. Possible interventions that may influence the progressive disease process include intensive insulin therapy and aldose reductase inhibitors. This article reviews the proposed pathogenetic mechanisms underlying diabetic neuropathy, their effects on nerve histomorphometric changes and ultrastructure typical of diabetic neuropathy, and potential therapeutic interventions and their impact on disease progression.
