Rescue Therapy for Helicobacter Pylori Eradication Treatment

Phase 4
Completed
Conditions
Helicobacter Pylori Infection
Interventions
Drug: Tetracycline,Metronidazole
Drug: Minocycline,Metronidazole
Registration Number
NCT04531059
Lead Sponsor
Shanghai Jiao Tong University School of Medicine
Brief Summary

Current guidelines have recommended classical bismuth-containing quadruple therapy including proton-pump inhibitor, bismuth, tetracycline, metronidazole as the empirical rescue therapy. However, tetracycline is clinically unavailable in China and the high frequency of adverse events of bismuth quadruple therapy often result in poor compliance, which limited the applicability of this recommendation. This study aimed to compare the efficacy and tolerability of a 14-day bismuth-containing quadruple rescue therapy in which tetracycline was replaced by minocycline.

Primary Outcome Measures
NameTimeMethod
Helicobacter pylori eradication rateSix weeks after completion of therapy

Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (\<4‰) (4‰ as the cutoff value).

Secondary Outcome Measures
NameTimeMethod
Rate of adverse effectsWithin 7 days after completion of therapy

The subjects were asked to grade the severity of adverse events according to their influence on daily activities, experienced as "mild" (transient and well tolerated), "moderate" (causing discomfort and partially interfering with daily activities), or "severe" (causing considerable interference with daily activities)

Compliance rateWithin 7 days after completion of therapy

Compliance was defined as poor when they had taken less than 80% of the total medication
