L-谷氨酰胺和左旋肉碱改善维持性血液透析患者营养状况的多中心、随机临床研究

目的：观察L-谷氨酰胺和左旋肉碱（L-肉碱）在维持性血液透析（maintain hemodialysis,MHD）患者营养不良治疗中的作用。方法：采用多中心、随机的方法将78例MHD患者随机分成A组、B组、C组,3组患者均皮下注射重组人促红细胞生成素（erythropoietinin,EPO）6000U,2次/周;A组每次血液透析结束时静脉注射L-肉碱2g,3次/周;B组每日口服L-谷氨酰胺胶囊1.5g（分3次口服）;C组联合使用L-肉碱和L-谷氨酰胺,用法不变。观察时间3个月。结果：C组患者血细胞比容（haematocrit,HCT）、血红蛋白（haemoglobin,Hb）、血浆总蛋白（plasma total protein,Tp）、血浆白蛋白（serum albumin,Alb）上升幅度明显高于A组和B组（P〈0.05或P〈0.01）,C组血C反应蛋白（C-reactive protein,CRP）水平明显低于A组和B组（P〈0.01）,免疫球蛋白（IgA、IgG、IgM）水平明显高于A组及B组（P〈0.01）。结论：MHD患者联合使用L-谷氨酰胺和L-肉碱可显著改善患者的营养状况及免疫功能;减轻体内微炎症反应;改善对EPO的敏感性,减少用量,提高疗效;安全性较好。

L-Glutamine and L-Carnitine in Maintenance Hemodialysis Patients to Improve Nutritional Status of the Multi-center Randomized Clinical Approach

Objective:To assess the efficacy of L-glutamine and L-carnitine in the treatment of maintenance hemodialysis patients with malnutrition.Methods:A multi-center approach of seventy-eight on malnutrition maintenance hemodialysis patients were randomly divided in to 3 groups: group A,group B and group C.Three groups were treated by EPO (6 000 u,two times each week by subcutaneous injection).In addition,2 g of L-carnitine was infused after each hemodialysis is treatment,three times each week in group A;oral L-gl...
