Conclusions. The growing epidemic of type 2 diabetes and its cardiorenal complications place a major burden on our health care system. Diabetic kidney disease is of particular importance in Asian populations including Chinese. In this series of studies, using a large prospective cohort established since 1995, I confirmed the powerful predictive value of albuminuria on cardio-renal complications. Inhibition of the RAAS interacted with both modifiable and genetic factors, notably the ACE I/D polymorphism, on the development of cardio-renal complications. In addition, it was found that CKD predicts CVD independent of albuminuria. Based on two prospective studies, I confirmed the effectiveness of global risk-factor control using structured care protocol to prevent these devastating complications. (Abstract shortened by UMI.) / I then examined the possible independent and interactive effects of CKD and albuminuria on cardio-renal outcomes in the original cohort of 5,004 patients. Glomerular filtration rate was estimated (eGFR) by the Modification of Diet in Renal Disease equation. The frequency of CKD as defined by eGFR <60ml/min/1.73m 2 was 15.8% in the cohort at baseline, when 6% of patients had serum creatinine ≥150mumol/L. / In collaboration with colleagues, I have conducted a series of studies to examine the prognostic factors for cardio-renal complications in Chinese type 2 diabetic patients. The modulating effects of RAAS inhibition and the effectiveness of rnuitidisciplinary care to prevent ESRD are also examined. / Research Hypotheses. (1) Albuminuria is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients; (2) Chronic Kidney Disease is associated with other metabolic risk factors and phenotypes and is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients; (3) Angiotensin-converting-enzyme insertion/deletion polymorphism is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients, and has an effect on treatment responses with RAAS blockage with ACE inhibitors; (4) Structured care models by risk stratification using various prognostic factors and adherence to care protocol can improve cardio-renal outcome in type 2 diabetes patients. / Results. In a prospective cohort of 5,004 patients, I examined the effect of albuminuria and ACE inhibition on survival and cardio-renal outcomes in 3,773 patients who had been observed for at least 6 months with a mean follow up period of 35.8 months. / Taken together, measurement of serum creatinine alone without GFR estimation may underestimate the frequency of CKD in Chinese type 2 diabetic patients. Estimated GFR was inversely associated wit-29h an increasing frequency of micro- and macrovascular complications cross-sectionally and an increased risk of all-cause mortality prospectively, independent of albuminuria and metabolic control. / So Wing Yee. / Source: Dissertation Abstracts International, Volume: 70-06, Section: B, page: 3422. / Thesis (M.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 203-243). / Electronic reproduction.
