Brief description Up to one third of patients with type 2 diabetes develop kidney disease (diabetic nephropathy). An increase in protein excretion in the urine (albuminuria) is usually the first sign of kidney disease. Albuminuria usually progresses from normal levels to an intermediate phase (microalbuminuria) lasting 5-10 years and is then followed by overt nephropathy (macroalbuminuria). It has been traditionally believed that onset of a decline in kidney function, measured as glomerular filtration rate, accompanies the development of diabetic kidney disease. However, recent studies by our group have shown that about one quarter of patients with type 2 diabetes have impaired kidney function without an increase in albuminuria. This raises the possibility that an alternate non-albuminuric pathway leads to kidney disease in a subgroup of patients with type 2 diabetes. This study will compare kidney structure and function in patients with type 2 diabetes and impaired kidney function with or without increases in albuminuria. The comparison will be accompanied by measurements of the rate of decline in kidney function over 5 years or more, in subjects with or without increases in albuminuria in order to confirm that kidney function may decline independently of albuminuria. The demonstration of alternate mechanisms of renal injury has the potential to identify new targets for the treatment of kidney disease in patients with type 2 diabetes.
