即使使用目前最有效的治疗方法,还是有一部分患者不能彻底根除幽门螺旋杆菌(HP)感染。西班牙研究人员进行此研究的目的是评价利福布汀治疗HP感染的效果。得出结论为阿莫西林,克拉霉素,甲硝唑,四环素,左氧氟沙星多联(通常三联)等主要抗生素根除HP失败后,采用含有利福布汀的挽救疗法令人鼓舞。相关内容发表在2012年1月份《alimentary pharmacology & therapeutics》上。

采用的方法是对美国医学文献数据库进行书目相关的检索。综合了包含利福布汀的治疗方案根除HP感染疗效的相关数据并且使用广义倒方差法法进行荟萃分析。

结果发现体外实验表明利福布汀根除HP效果良好。HP对利福布汀的平均耐药率(数据来自于11项研究,包括2982例患者)为1.3%(95%置信区间= 0.9-1.7%)。当仅考虑包含初次接受HP根除治疗患者的研究时,这个数字甚至更低(0.6%)。另一方面,当仅考虑治疗后的患者时,利福布汀耐药率更高(1.59%) 。总之,含有利福布汀的治疗方法(意向性分析)平均HP清除率(1008例患者)为73%(67–79%)。二线(223例),三线(342例)和第四/五线(95例)利福布汀治疗的治愈率分别为79%(67-92%),66%(55-77%)和70%(60-79%)。几乎所有的研究都给予利福布丁300毫克/天用于治疗幽门螺旋杆菌感染,这个剂量可能比150mg/天更有效。治疗的最佳时间仍然不清楚,但一般建议疗程为10-12天。副作用的平均率为22% (19–25%)。虽然骨髓毒性这个并发症比较罕见,但其是最严重的并发症。到目前为止,所有患者在几天内白细胞减少症均能恢复到正常,尚无感染或其它相关不良预后的报告。
