摘要 目的观察口服谷氨酰胺对5-氟尿嘧啶(Fu)/甲酰四氢叶酸(FA)引起的肠道吸收(IA)和肠道通透性(IP)的影响。方法将54例结直肠癌化疗患者随机分为谷氨酰胺组24例及安慰剂组30例,自化疗(静注Fu 450mg/m2和FA 100 mg/m2)开始前的第5天起,谷氨酰胺组口服谷氨酰胺18 g/d,安慰剂组口服安慰剂,均连续治疗15 d。在化疗开始前和化疗第1周期结束后采用D-木糖尿排泄试验和纤维二糖—甘露醇试验测定患者IA率和渗透率,记录患者每天的腹泻次数及其他不良反应。结果化疗后IA和IP显著恶化,化疗后谷氨酰胺组D-木糖平均值及乳果糖—甘露醇比值与安慰剂组比较差异显著,P均<0.05。与谷氨酰胺组相比,安慰剂组腹泻持续时间较长,腹泻的受试者曲线较大,但两组比较差异无统计学意义。安慰剂组服用洛哌丁胺片的平均数量明显高于谷氨酰胺组,P均<0.05。结论谷氨酞胺可以缓解化疗药造成的肠黏膜损伤、肠黏膜萎缩、肠黏膜通透性升高。
