Diabetic Nephropathy Diabetic Nephropathy 1Statistical Increase in DiabetesIn the past 20 years,there has been a steady increase in the proportion of all patients with ESRD who have diabetes.According to the 1997 report of the USRDS,more than 40%of all newly treated patients with ESRD have diabetes.Statistical Increase in Diabet2Increasing Insulin Treatment in NIDDMIncreasing Insulin Treatment

of Nephropathy.The interrelationships between functionaland morphologic markers of the stages of diabetic nephropathy are shown.Additional pathologic studies are needed to time with precision exactly

glomerular hyperfiltration are subtle pathophysiologic manifestations of early DN,transformation to overt clinical DN takes place over months to many years.While not all microalbuminuric individuals progress to proteinuria and azotemia,the majorityare at risk for ESRD due to DN.Diabetic Nephropathy in Types 11糖尿病肾病及慢性肾功能不全的预防控制血糖控制血压低蛋白饮食对AGES的治疗糖尿病肾病及慢性肾功能不全的预防控制血糖12Clinical recognition of diabetic nephropathy.The timing of reno-protective therapy in diabetes is a subject of current inquiry.Certainly,hypertension,poor metabolic regulation,and hyperlipidemia should be addressed in every diabetic individual at discovery.Discovery of microalbuminuria is by consensus reason to start treatment with an ACEI in either type of diabetes,regardless of BP elevation.However,nearly the entire course of renal injury in diabetes is clinically silent.Medical intervention during this“silent phase,”comprising BP pressure regulation,metabolic control,dietary protein restriction,and administration of ACEI is renoprotective,as judged by slowed loss of GFR.Clinical recognition of diabet13PROGRESSION OF COMORBIDITYIN TYPE II DIABETESCOMORBIDITY INDEXHEART DISEASEComplications

and HD,lower curve)is evident in these survival curves drawn from the 1997 report of the URDS.Fewer than 1 in 20 diabetic patients with ESRD treated with any form of dialysis will live a decade.In contrast,kidney transplantation from a LD(upper curve)or a CAD(middle curve)permits substantive cohorts to survive.Survival Rates of Diabetic ESR21糖尿病肾病(英文)课件22
