Brief Summary

Helicobacter pylori (H. pylori) is still infecting more than half of the population in many countries, although the prevalence is decreasing. As a main cause of chronic gastritis, peptic ulcer, and malignant gastric tumors, H. pylori places a heavy burden on developing countries and regions with high infection rate. In the last decade, the eradication rates of conventional regimens based on proton pump inhibitors (PPIs) plus antibiotics have been decreasing. Antibiotic resistance and decrease of drug compliance caused by adverse effects were the two main reasons for eradication failure. Moreover, H. pylori treatment causes dysbiosis of gut microbiota and increases the expression of antibiotic resistance gene. Therefore, eradication of H. pylori is facing a great challenge, and effective and safe methods are needed. To reduce adverse effects, improve drug compliance and increase eradication rates, certain probiotics were added to conventional regimens in several clinical studies. Probiotics were more or less shown to reduce adverse effects in the vast majority of clinical studies, but whether probiotics can improve the eradication rate of H. pylori remains controversial. Meanwhile, several studies focusing on the impact of probiotics on gut microbiota during H. pylori eradication have been published recently. Thus, we conducted a randomized, double-blind, placebo-controlled trial aiming to evaluate the effects of probiotics combining with 14-day bismuth quadruple therapy on H. pylori eradication.

Outcome Measures

Primary Outcomes (1)

  • Gut microbiota

    Stool samples were collected at wk0, wk2, and wk10. Patients were instructed to collect stool samples at the medical visit site by using disposable sterile feces collection tubes. Samples were stored at -80℃ after collection immediately. In this study, the influences of antibiotics and combination of probiotics on gut microbiota during H. pylori treatments were investigated using high-throughput sequencing of the 16S rRNA gene.

    Week 0, week 2 and week 10

Secondary Outcomes (2)

  • Rate of adverse reactions

    Week 2 and week 10

  • Patient compliance

    Week 10

Study Arms (2)

Probiotic group

EXPERIMENTAL

Esomeprazole 20 mg and bismuth 2g twice daily before meals, amoxicillin 1 g, and clarithromycin 500 mg twice daily after meals, probiotic once a day with one packet each time 2 hours after taking medicine above in the evening, for 2 weeks.

Dietary Supplement: Bifidobacterium animalis subsp. lactis BLa80

Placebo group

PLACEBO COMPARATOR

Esomeprazole 20 mg and bismuth 2g twice daily before meals, amoxicillin 1 g, and clarithromycin 500 mg twice daily after meals, placebo once a day with one packet each time 2 hours after taking medicine above in the evening, for 2 weeks.

Other: Placebo

Interventions

Test product contain 3 × 109 colony-forming units \[CFU\] Bifidobacterium animalis subsp. lactis BLa80 strains, for each packet. Subjects ingested one packet (3 g/packet) of Test product per day (2 hours after taking antibiotics in the evening), for 14 days.

Probiotic group
PlaceboOTHER

To maintain the blinding, patients in the control group received placebo included in identical packets. Control product per day (2 hours after taking antibiotics), for 14 days.
