effect of sulodexide on albuminuria in chinese type 2 diabetic patients

Conditions: Diabetic Nephropathy; Albuminuria

Summary: current therapies targeting albuminuria in diabetic nephropathy leave residual urinary albumin secretion, which meanwhile leave residual cardiovascular risk. previous studies demonstrated that sulodexide could reduce albuminuria in type 2 diabetic patients. but no data concerning chinese population is available. the investigators aim to provide evidence of effects of sulodexide on diabetic nephropathy in chinese diabetic patients. further the investigators also test the hypothesis that sequential administration of intravenous and oral replacement of the drug would gain an earlier and greater reduction of albuminuria, compared with oral use only.
