Objective Familial transmission can possibly influence the infection and treatment of Helicobacter pylori . This study aimed to describe the prevalence of H . pylori infection and outcomes of eradication treatment among Vietnamese patients who live in the same households. Methods We conducted a prospective cohort study of Vietnamese household members with upper gastrointestinal complaints. Participants received esophagogastroduodenoscopy and H . pylori testing. The H . pylori -positive patients were treated and asked to return for follow-up within 4 months. To explore factors associated with H . pylori infection at baseline, we performed multilevel logistic regression to account for the clustering effect of living in the same households. To explore factors associated with eradication failure, we used Poisson regression with robust variance estimation to estimate the risk ratio. Results The prevalence of H . pylori infection was 83.5% and highest among children <12 years old (92.2%) in 1,272 patients from 482 households. There were variations in H . pylori infection across households (intraclass correlation = 0.14, 95% confidence interval (CI) 0.05, 0.33). Children aged <12 years had higher odds of H . pylori infection (odds ratio = 3.41, 95%CI 2.11, 5.50). At follow-up, H . pylori was eradicated in 264 of 341 patients (77.4%). The risk of eradication failure was lower for the sequential regimen with tetracycline. Conclusion H . pylori infection was common among people living in the same households. Eradication success for H . pylori was higher for the tetracycline sequential regimen. More research should be focused on how family factors influence H . pylori infection and on eradication treatment.
