小肠细菌过度生长(SIBO)是由于上消化道菌群发生了改变。质子泵抑制剂(PPI)被认为是SIBO风险因素,然而,已发表的PPI治疗和SIBO发生风险相关性的报告得出了不一致的结论。本研究的目的是通过葡萄糖氢呼气试验(GHBI)评价使用PPI治疗和未使用PPI治疗患者SIBO发病率。在这项大规模、统计功效充分的等效性研究中,得出的结论是通过葡萄糖呼气试验,未发现PPI与SIBO阳性有明显相关性。该研究2012年2月14日在线发表于《The American Journal of Gastroenterology》。

该研究使用的方法是对2004年至2010年期间所有接受GHBT测试患者的回顾性图表总结。在摄入50克口服葡萄糖载量前和摄入后每20分钟(共120分钟)收集氢气(H2)和甲烷(CH4)呼气样本。使用下列标准定义GHBT阳性,(a)H2超过基线20 PPM,(b)H2持续上升超过基线10 PPM ,(c)CH4超过基线百万分之15 ,(d)H2上升超过基线20 PPM或CH4超过15 PPM。

结果总共有1191例患者(70%女性)纳入试验,其中566例(48%)使用了PPI治疗。无论使用哪种诊断标准均没有发现PPI使用者与未使用者的GHBT阳性有显著区别并且PPI使用与GHBT阳性有明显联系。通过使用H2>20诊断标准发现,GHBT阳性与年龄较大(比值比(OR)1.03,95%可信区间(CI)1.01-1.04)和止泻药的使用(OR 1.99,95% CI 1.15–3.44)有关。

使用H2>10诊断标准发现,GHBT阳性与年龄较大(OR 1.01, 95% CI 1.00–1.02)和腹泻(OR 1.53, 95% CI 1.13–2.09)有关。使用H2>20或CH4>15诊断标准发现,GHBT阳性与年龄较大(OR 1.01, 95% CI 1.00–1.02)有关。
