ABSTRACT
Objective To explore the effects of losartan potassium and simvastatin combination therapy on oxidative stress indicators in diabetic patients on peritoneal dialysis through 12 weeks observation. Methods Diabetic patients with end-stage nephropathy (n=80) who were treated with continuous ambulatory peritoneal dialysis were randomly divided into two groups:control group who received routine treatment (n=40), treatment group who were given losartan potassium 50 mg, once per day and simvastatin 20 mg, once every night (n=40). HbA1C, Insulin dosage, Oxidative stress indicators(SOD, GSH-PX, MDA and Hcy)were compared between two groups before and after peritoneal dialysis. Results There was no significant difference of HbA1C between the 2 groups before and after treatment(P>0.05). The insulin doses increased be?fore dialysis in both groups after CAPD treatment. It is lower in the treatment group than that in the control group ( P<0.05). The expression levels of GSH-PX and SOD in treatment group were higher while the expressions of Hcy and MDA were lower after treatment. The expressions of GSH-PX and SOD were higher while the expressions of Hcy and MDA were lower in treat?ment group than those in control group when comparing the same time point(P<0.05). GSH-PX expression level was lower while the expressions of MDA and Hcy were higher after dialysis than those before dialysis in control group ( P<0.05). Con?clusion Losartan potassium combined with simvastatin treatment can improve curative effect and oxidative stress indicators in diabetic patients on peritoneal dialysis.
