RESUMO
Objective To observe the therapeutic effect of glycosaminoglycans(GAGs)on diabetes mellitus with early nephropathy in order to find a new therapeutic approach to diabetic nephropathy. Methods 60 cases of type 2 diabetic nephropathy(albuminuria:30 to 300mg/24h,male/female:38/22,ages:43-70 years old, course of disease:1-30 years)without hypertension were selected. Some indexes were analyzed before and after administration of regular therapy in routine group or glycosaminoglycans group. The elderly group and non elderly group of diabetes nephropathy were compared. When the metabolism is stable, the levels of endothelin (ET), Netricoxide (NO)and urinary albumin excretion rate(UAER)were measured. Results After three months treatment, the levels of UAER were decreased significantly in both GAGs group and routine group(P＜0.01).After three months, UAER was decreased step by step, and there was no difference between the two groups. The levels of UAER had no change in regular group and there was significant difference between this group and the other two groups. In GAGs group, the levels of whole blood viscosity of medium shear rate 1,whole blood viscosity of medium sheer rate 2,whole blood viscosity of low shear rate were declined and serum NO increased significantly; that of plasma viscosity, whole blood reduced viscosity, ET were all decreased to some degree. Conclusion GAGs has the therapeutic effect on type 2 diabetic nephropathy patients with microalbuminuria because of decreasing UAER and reversing the development of DN. The benefit was positively correlated with the time of taking glycosaminoglycans.
