使用抗生素后的腹泻是临床上经常出现的问题。益生菌对住院成人人群预防AAD的作用仍不清楚。本研究旨在评估补充益生菌的酸奶对住院患者抗生素相关性腹泻(AAD)的预防效果,研究结果已在线发表于J Clin Gastroenterol。

本项随机、双盲、安慰剂对照的临床试验纳入开始接受抗生素治疗的住院患者。患者随机分组(2:2:1),接受每天200 mL安慰剂酸奶(嗜热链球菌和保加利亚乳杆菌亚种)、200 mL益生菌酸奶(之前加上嗜酸乳杆菌La-5、动物双歧杆菌乳酸菌Bb-12和和干酪乳杆菌亚种Lc-01),或在开始抗生素治疗后48小时内和停用抗生素后5天内不喝酸奶(无盲对照)。对患者进行1个月的随访,以确定腹泻的发生情况。

 

结果,研究纳入314名患者,平均年龄76岁。益生菌组的腹泻率为23.0%,而安慰剂组为17.6%,绝对风险降低-5.35%(95%置信区间,-15.4%~4.7%;P=0.30)。无盲外对照组和盲法研究组合并的腹泻率相似(分别为20.9% vs. 20.2%;P=0.91)。各组间腹泻持续时间、最大排便次数或因腹泻而延长入院时间无差异。各组间全因死亡率无差异。

 

综上所述,该研究结果表明,联合益生菌菌株LA-5、BB-12、LC-01对住院患者AAD的预防没有影响。
