RESUMO
End Stage Renal Disease (ESRD) is a common consequence of diabetic nephropathy (DN). DN is the major cause of death in patients with IDDM, accounting for greater than 40% of deaths with this form of diabetes. There is no clearly documented therapeutic technique that will prevent or reverse progressive renal damage in IDDM. While pancreatic transplantation and "cure" of diabetes in experimental animals may be associated with some histological reversal of renal pathology, this has not been documented in humans. Most studies agree that once diabetic renal disease is present (as documented by proteinuria), progression is inevitable, albeit the rate of progression may be altered by different therapeutic methods. There is considerable hope that "tight metabolic control" will prevent the initial damage that leads to DN and ESRD, but evidence remains inconclusive. There is some evidence that careful monitoring for microalbuminuria will allow for very early detection of damage and alterations in therapy. Our studies have documented a decrease in both morbidity and mortality in IDDM in patients who have been competitive athletes, suggesting that promotion of physical fitness may be a valuable means of delaying progression of renal disease while control of BP delays progression. Early detection and aggressive therapy is recommended. Some studies utilizing diets low in sodium and/or protein appear beneficial but more studies are needed before pediatric application.
