The consensus of North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and Maastricht III recommend 1-week proton pump inhibitor-based triple therapy as the standard first-line choice to achieve eradication rates in the range of 75% to 85% for pediatric H pylori infection.2Gold B.D.

We found that the sequential therapy is better, but not statistically significantly different on intention-to-treat analysis (24/34 [70.1%] vs. 34/57 [59.6%], P = .43) from triple therapy. However, it was striking to show that 21% (7/34) of our children receiving the sequential therapy had poor drug compliance (defined as less than 75% tablets used). Within the group, the eradication rate was significantly higher in children with good drug compliance than in those with poor compliance (23/27 [85.2%] vs. 1/7 [14.3%], P = .001).We agree that sequential therapy is a powerful strategy to improve H pylori eradication in children. However, because of the rather complex 10-day regimens of sequential therapy, need for adherence to the therapies should be emphasized to parents. Francavilla et al1Francavilla R. Lionetti E.
