【摘要】 目的 观察静脉用 维生素C与促红细胞生成素联合应用治疗尿毒症铁超负荷患者肾性贫血的疗效。方法 选择北京市通州区潞河医院血透中心18 例患者,其血清铁(SF)>800 ng/mL,和或铁饱和度(TSAT)>50%,将维生素C 1.0 g加入0.9%生理盐水100 mL中于每次透析结束前半小时泵后静脉滴注,观察12 周,进行自身对照,记录用药前后患者Hb,Hct,SF,TSAT的变化。结果 治疗12 周后,患者Hb,Hct上升,SF,TSAT下降,与用药前比有显著性差异(P<0.01)。结论 尿毒症维持性血液透析铁超负荷患者联合应用维生素C与促红细胞生成素可提高血红蛋白水平,改善贫血。

Therapeutic Effect (Observation) of Vitamin C Combined withErythropoietin in the Patients of Renal AnemiaLIU Yongquan,YUE Lingju
(Tongzhou Luhe Hospital,Beijing 101149 China)Abstract:Objective To observe the efficiency of intravenous vitamin C combined with erythropoietin in the treatment of renal anemia. Methods 14 uremia patients in Haemodialysis center of the Luhe Hospital with serum ferritin (SF)>800ng/ml and transferrin saturation (TSAT)>50% were chosen. These patients received intravenous transfusion of vitamin C 1.0g added to 100ml 0.9% NS half an hour before the finish of the dialysis. The observation lasted 12 weeks. The changes of Hb, Hct, SF, and TSAT were determined before and after the treatment, using data before the treatment as control. Results Hb and Hct increased while SF and TSAT decreased significantly in statistics in these patients after 12-week treatment, compared with data before the treatment (P<0.01). Conclusions Combination of vitamin C and erythropoietin is effective in improving the Hb levels in the uremia patients receiving maintenance hemodialysis with iron overload.

贫血是尿毒症病人主要的并发症,促红细胞生成素的应用使肾性贫血的治疗有了根本的改观,铁缺乏是影响促红细胞生成素疗效的主要因素之一[1]。在临床中,我们发现尿毒症贫血病人中有一部分为铁缺乏,还有一部分病人为铁超负荷。铁超负荷病人的贫血单靠促红细胞生成素亦很难纠正。可能与外源性铁摄入增加或铁利用障碍有关。有文献报道治疗铁超负荷可用维生素C或去铁胺[2]。我院血透中心试用静脉用维生素C与促红细胞生成素联合应用的办法治疗此类病人的贫血,取得较好疗效,血红蛋白均有提高,现报告如下。
