Rescue Therapy for Helicobacter Pylori Infection
October 23, 2023 updated by: Hong Lu, MD, Shanghai Jiao Tong University School of Medicine
Rifabutin-containing Triple Therapy for Helicobacter Pylori Rescue Treatment: a Randomized Controlled Trial
Dual therapy containing vonoprazan and amoxicillin had showed excellent eradication results with Helicobacter pylori first-line treatment.
However, no study has examined its efficacy for H. pylori rescue treatment.
Rifabutin has low antibiotic resistance, superior antibacterial activity in vitro, and stability in the gastric acid environment.
Several studies have confirmed the efficacy of rifabutin-containing triple therapy as a first-line or rescue treatment for H. pylori.
The purpose of this study was to evaluate the efficacy and safety of dual therapy vesus rifabutin-containing triple therapy versus classical bismuth-containing quadruple therapy as rescue therapy for the eradication of refractory Helicobacter pylori.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Helicobacter pylori eradication rate
Time Frame: Six 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).
|
Six weeks after completion of therapy
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Compliance rate
Time Frame: Within 7 days after completion of therapy
|
Compliance was defined as poor when they had taken less than 80% of the total medication
|
Within 7 days after completion of therapy
|
Rate of adverse effects
Time Frame: Within 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).
In addition, blood test were messured to access function of liver and kidney.
