CANHelp Working Group Treatment Trials
Canadian North Helicobacter Pylori (CANHelp) Working Group Treatment Trials
연구 개요
상세 설명
The CANHelp Working Group is a collaborative team that links University of Alberta researchers with Canadian northern community leaders and health officials in a collaborative effort to investigate H. pylori infection with the goal of finding solutions to community concerns about health risks. The research program uses a community-driven research approach in northern communities to characterize the burden of disease from H. pylori infection and exchange knowledge with community members and decision makers to identify ways to reduce health risks from this infection.
For the participating communities, the treatment trials aim to:
- Estimate the effectiveness of alternate H. pylori treatment regimens to identify optimal regimens for the local setting
- Identify factors external to the treatment regimen that influence short- and long-term treatment success

Post-treatment H. pylori status by urea breath test
기간: A minimum of 10 weeks after participant has completed treatment
|
Treatment effectiveness, defined as the probability (average risk) of elimination of H. pylori infection following treatment, measured as the proportion of trial participants with a negative post-treatment urea breath test at least 10 weeks following completion of treatment. Using an intention-to-treat analysis, the denominator for this proportion is the number of trial participants assigned treatment. Using a per-protocol analysis, the denominator for this proportion is the number of trial participants who completed treatment and were tested post-treatment. Participants are administered a urea breath test using 13C-labeled urea dissolved in a citric acid solution. We use the following test value classifications for determining the outcome: >=4.0 (Positive for H. pylori infection) Between 2.5 and 4.0 (Borderline; repeat test) Between 2.4 and -1.99 (Negative for H. pylori infection) Less than -2.0 (Uncertain test result, repeat test) |
