Helicobacter pylori is a common infection associated with many gastrointestinal diseases. Triple or quadruple therapy is the current recommendation for H pylori eradication in children but is associated with success rates as low as 50%. Recent studies have demonstrated that a 10-day sequential therapy regimen, rather than simultaneous antibiotic administration, achieved eradication rates of nearly 95%. This meta-analysis found that sequential therapy increased eradication rates by 14.2% (relative risk [RR] = 1.142; 95% confidence interval [CI] = 1.082-1.207; P < .001). Ten-day sequential therapy significantly improved H pylori eradication rates compared to the 7-day standard therapy (RR = 1.182; 95% CI = 1.102-1.269; p < .001) and 10-day standard therapy (RR = 1.179; 95% CI = 1.074-1.295; P = .001), but had lower eradication rates compared to 14-day standard therapy (RR = 0.926; 95% CI = 0.811-1.059; P = .261). The use of sequential therapy is associated with increased H pylori eradication rates in children compared to standard therapy of equal or shorter duration.
