Low-dose heparin micro-pump continuous regular infusion in the treatment of primary nephrotic syndrome / 中国小儿急救医学

ABSTRACT

Objective To explore the efficacy and safety of low-dose heparin in the treament of children with primary nephrotic syndrome (PNS). Methods It was an open and comparative trial. Eightyeight children with PNS in the hypercoagulable state,on the basis of administrating with glucocorticosteroid,were administrated with low-dose heparin that infused by micro pump oriented to time ( group A). Eighty patients only treated with glucocorticosteroid were chosen as control (group B). Results Serum-albumin and activated partial thromboplastin time (APTT) increased,but fibrinogen (Fib) decreased after therapy in the group A,and they all showed significant differences (P ＜ 0. 01 ). Serum-albumin increased after therapy in the group B and there was significant difference (P＜0. 01 ). However,APTT and Fib in the group B showed no significant difference( P ＞ 0. 05 ) between post-treatment and pretherapy. Post-treatment serum-albumin and APTT in the group A were significantly higher than those in group B, and Fib was significantly lower than that in group B ( P ＜ 0. 01 ). The rate of urine protein remission in group A (82/88) was significantly higher than that in group B (63/80). Urine protein remission time and edema disappearance time were significantly shorter in group A than group B ( P ＜ 0. 01 ). APTT of group A at the peak concentration of heparin after therapy was significantly higher than that of pretherapy ( P ＜ 0. 01 ), and the ratio was 2. 38. However, there was no significant difference in APTT at the valley concentration of heparin between post-treatment and pretherapy ( P ＞ 0.05 ). Conclusion Low dose-heparin infused by micro pump oriented to time in the treatment of children with PNS has an obvious anticoagulative effect. It can improve the rate of urine protein remission and shorten edema disappearance time. Meanwhile it is safety ,requires no laboratory monitor and has few drug side effects,thus it deserves further clinical application.
