Insights
Sequential therapy significantly improves Helicobacter pylori eradication rates in children compared to standard treatments. This 10-day regimen offers higher success, making it a more effective option for pediatric H. pylori infections.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Pharmacotherapy
Background:
- Helicobacter pylori infection is prevalent in children, linked to various gastrointestinal disorders.
- Current standard treatments (triple/quadruple therapy) for H. pylori eradication in children show limited efficacy, with success rates around 50%.
Purpose of the Study:
- To evaluate the efficacy of a 10-day sequential therapy regimen for H. pylori eradication in pediatric patients.
- To compare the eradication rates of sequential therapy with standard antibiotic regimens of varying durations.
Main Methods:
- A meta-analysis was conducted to synthesize data from relevant studies.
- Eradication rates were compared between sequential therapy and standard therapies (7-day, 10-day, and 14-day) using relative risk (RR) and confidence intervals (CI).
Main Results:
- Sequential therapy demonstrated a significant increase in H. pylori eradication rates by 14.2% (RR = 1.142; 95% CI = 1.082-1.207; P < .001).
- Ten-day sequential therapy significantly outperformed 7-day (RR = 1.182) and 10-day (RR = 1.179) standard therapies.
- While effective, 10-day sequential therapy showed comparable eradication rates to 14-day standard therapy (RR = 0.926; P = .261).
Conclusions:
- Sequential therapy, particularly a 10-day regimen, significantly enhances H. pylori eradication rates in children compared to standard treatments of equal or shorter duration.
- This approach offers a more effective therapeutic strategy for managing pediatric H. pylori infections.
Abstract:
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.
