Abstract

Background/aims: The effects of probiotic supplementation on Helicobacter pylori (H. pylori) eradication therapy are not completely understood. In this study, we investigated the effects of continuous probiotic administration on eradication rates, recrudescence, and symptom response following completion of a course of H. pylori therapy.

Methods: This prospective, randomized, double-blind placebo-controlled trial was performed between June 2018 and 2020. Twohundred seventy patients who received a standard triple regimen for H. pylori eradication, were included in the study. Participants were randomized to receive a probiotic as adjunctive therapy (Enterococcus faecium 4.5×108 and Bacillus subtilis 5.0×107; Medilac-S®, Hanmi Pharmaceuticals, Seoul, Korea) or a placebo (one tablet thrice daily) for 28 days, following H. pylori eradication. Participants who showed successful eradication underwent a repeat 13C-urea breath test after 6 months.

Results: Eradication rates in the probiotic and placebo groups were 77.1% and 72.4%, respectively (P=0.48) using per-protocol analysis. Using intention-to-treat analysis, eradication rates were 67.4% and 65.9%, respectively (P=0.43). Of 149 patients who were followed-up after 6 months, four patients had recrudescence (2.7%). Recrudescence rates did not differ between the probiotic and placebo groups. Of the 76 patients who had non-ulcer dyspepsia, 60 (78.9%) showed symptom resolution after 6 months. This beneficial effect was most pronounced in patients with postprandial distress syndrome (P=0.02).

Conclusions: Consecutive probiotic supplementation following H. pylori eradication therapy did not increase eradication rates or decrease recrudescence rates.

益生菌补充剂治疗幽门螺杆菌感染的双盲随机临床试验
背景/目的:补充益生菌对幽门螺杆菌(h.p ylori)根除治疗的影响尚未完全了解。在这项研究中,我们调查了在完成一个疗程的幽门螺杆菌治疗后,持续使用益生菌对根除率、复发和症状反应的影响。方法:该前瞻性、随机、双盲安慰剂对照试验于2018年6月至2020年进行。270名接受根除幽门螺杆菌标准三联疗法的患者被纳入研究。参与者随机接受益生菌作为辅助治疗(屎肠球菌4.5×108和枯草芽孢杆菌5.0×107;Medilac-S®,Hanmi Pharmaceuticals, Seoul, Korea)或安慰剂(每日三次,一片),在幽门螺杆菌根除后服用28天。成功根除的参与者在6个月后再次进行13c -尿素呼吸测试。结果:按方案分析,益生菌组和安慰剂组的根除率分别为77.1%和72.4% (P=0.48)。意向治疗分析显示,根除率分别为67.4%和65.9% (P=0.43)。149例患者6个月后随访,4例复发(2.7%)。复发率在益生菌组和安慰剂组之间没有差异。76例非溃疡性消化不良患者中,60例(78.9%)在6个月后症状缓解。这种有益效果在餐后窘迫综合征患者中最为明显(P=0.02)。结论:在幽门螺杆菌根除治疗后连续补充益生菌不会增加根除率或降低复发率。
