Summary

Diabetes is the leading cause of chronic kidney disease in developed countries. About 30-40% of patients with type 1 and type 2 diabetes mellitus will develop diabetic nephropathy. Microalbuminuria is often used as an early predictor of diabetic nephropathy. Many studies already demonstrated the renoprotective effect of Renin-angiotensin-system (RAS) blockers in patients with varying degree of albuminuria, few studies focus on studying the decline in glomerular filtration rate (GFR) among patients with normoalbuminuria. However a substantial number of diabetic patients exist with sub-normal GFR without microalbumin excretion. From literature, diabetes mellitus will have faster decline in GFR but the investigators do not know whether such decline can be slowed down by the use of RAS blockers as compared with other anti-hypertensive drugs. This Study investigate the effect of early treatment with RAS blockers on the decline rate of GFR in diabetic patients with normoalbuminuria.
