Abstract:
Objective To investigate the significance of renal tubular dysfunction in patients with refractoriness nephrotic syndrome(RNS)and the effect of interference treatment of Valsartan (VAL).Methods 79 cases of RNS and 68 healthy controls were recruited into the study. The 79 patients of RNS were divided randomly into the VAL group and the dipyridam group. On the basis of routine therapy, the VAL group was given VAL(80mg/d),and the dipyridam group taken dipyridam (150mg/d)orally for 12 weeks The glomerular tubular function(u-RBP,α1-MG,β2-MG,mAlb,NAG)were detected and the pathologic changes of tubukinterstitium were observed by using the methods of ELISA, biochemistry and scoring of the pathologic damage of tubulointerstitium before and after 12 weeks of VAL treatment in all of the cases. Results Urinary RBP,α1-MG,β2-MG,mAlb and NAG in all patients with RNS was evidently higher than that in healthy controls(P＜0.01).Those had positive correlations with damages of tubulointerstitium(r=0.436,0.626,0.499,0.668,0.657,P＜0.01).The interference outcome displayed that the excretion rates of urinary series of protein after oral use VAL in treatment group were markedly lower, while the control group had no distinct change. Conclusion There were various injury of tubulointerstitium and the disfiguration of renal tubular function in all cases with RNS. Damages of renal tubular function had positive correlation with tubulointemtitium injury and renal globular injury. Interference treatment with ARB in patients with RNS could improve renal tubular function, which is of great significance in delaying the progress of RNS.
