A follow-up of 1475 Type 1 (insulin-dependent) diabetic patients diagnosed before 1953 (815 males, 660 females) and before the age of 31 years was conducted. All patients were seen at the Steno Memorial Hospital and were referred from all parts of Denmark; 91 (6%) could not be traced. The rest (94%) were followed until death or for at least 25 years; 249 (17%) were followed for greater than 40 years. Clinical diabetic nephropathy developed in 531 (41%) of the 1303 patients in whom sufficient information was available regarding proteinuria. Other causes of proteinuria were found in 3%, and 57% did not develop persistent proteinuria. The prevalence of diabetic nephropathy was 21% after 20-25 years of diabetes duration followed by a decline to 10% after 40 years. Two incidence peaks of the onset of proteinuria were seen, one after 16 and another after 32 years duration of diabetes and was low after 35 years duration. The cumulative incidence was 45% after 40 years of diabetes. A male preponderance was seen among patients with nephropathy. A significant difference in the pattern of annual incidence rates of diabetic nephropathy was seen, when groups with onset of diabetes before 1933, between 1933-1942, and 1943-1952, respectively, were compared. An association between daily insulin requirement and nephropathy incidence was found. Patients with nephropathy had a much poorer survival than those without proteinuria; 40 years after onset of diabetes, only 10% of patients who developed nephropathy were alive, whereas greater than 70% of patients who did not develop nephropathy survived.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical diabetic nephropathy is a well-recognized cause of increased morbidity and mortality in patients with type 1 diabetes. The finding that microalbuminuria predicts progression to overt nephropathy has allowed early diagnosis and preventive interventions. Several studies have demonstrated that treatment with angiotensin-converting enzyme (ACE) inhibitors slows down the rate of decline of the glomerular filtration rate in type 1 diabetes patients with established proteinuria. The renoprotective properties of the ACE inhibitor captopril extend beyond its antihypertensive effects. ACE inhibitors represent the most appropriate class of antihypertensive drugs for treating type I diabetes patients because of their efficacy and safety. When microalbuminuria is detected and confirmed in a diabetic child or adolescent, and if it persists despite 6-12 months of improved metabolic control, treatment with ACE inhibitors should be started, even if the child is normotensive. Careful follow-up of renal function is essential.

Clinical diabetic nephropathy is characterized by an earlier functional phase in which hyperglycaemia is accompanied by an increased glomerular filtration rate and microalbuminuria; the persistence of this high-flow and high-pressure state, added to a poor control of hyperglycaemia, fosters renal damage and proteinuria, accompanied by a decline in glomerular filtration rate and progression to end-stage renal disease. In this review, we present glucose transporter 1 (GLUT-1) as a novel link that connects the glomerular hyperfiltration (hypertension) state and the complex cascade of events that leads to nephropathy. The interplay between angiotensin II and nitric oxide, and its interactions with reactive oxygen species, are also discussed, in an attempt to provide an integrated view of the pathophysiology of diabetic nephropathy.

Diabetic nephropathy is becoming an increasingly important cause of morbidity and mortality worldwide owing to the increasing prevalence of type 2 diabetes, largely driven by increasing obesity. There is considerable evidence that obesity, hypertension and other elements of the metabolic syndrome also contribute to the progression of renal disease independent of diabetes. How they interact and contribute to diabetic nephropathy, however, is not completely understood. Clinical diabetic nephropathy is preceded by an increase in glomerular filtration rate, microalbuminuria and glomerular hypertrophy. Poor glycemic control and elevated systolic blood pressure exacerbate proteinuria and renal injury that may culminate in end-stage renal disease. A similar sequence of events may lead to obesity-related renal disease even in the absence of diabetes. This chapter compares and contrasts factors involved in the development of glomerular hemodynamic and kidney pathological processes associated with diabetes and obesity.
