Helicobacter Pylori Infection and Gastric Disease in Bhutan: First Community-Wide, Population-Based Study
Bhutan1,043 participantsStarted 2019-12-05
Plain-language summary
Background: Helicobacter pylori is a major risk factor for gastric cancer, yet in many developing countries, including Bhutan where gastric cancer incidence is high, access to screening and eradication is limited. The investigators conducted the first large-scale, population-based survey of H. pylori infection and gastric disease in Bhutan to provide baseline data before the launch of a national gastric cancer prevention program.
Methods: Permanent residents aged ≥12 years from 24 villages under Dawakha Basic Health Unit II catchment area were enrolled (December 2019-March 2023). H. pylori status was determined by serum IgG testing, gastric atrophy by serum pepsinogen, and endoscopy was offered to high-risk groups.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
