Abstract:
Due to the decreasing eradication rate of Helicobacter pylori , some novel alternatives have been developed, such as bismuth‐containing quadruple therapy and non‐bismuth‐containing quadruple therapy (sequential and concomitant treatment). Little is known about whether a success rate above 90% can be achieved with these regimens in Chinese children. Methods In this prospective, open, comparative cross‐sectional study, we recruited treatment‐naïve children (aged between 6 and 18 years) with H pylori infection. The patients were assigned either standard triple therapy, sequential therapy, bismuth‐based quadruple therapy, or concomitant therapy at the discretion of the prescribing physician. H pylori infection was evaluated at least 4 weeks after the completion of the treatment. A negative urea breath test (UBT) indicated successful eradication. The primary endpoint was the eradication frequency of H pylori in the full analysis set (FAS), which included all children who received at least one dose of the treatment and with available follow‐up data. Results Between September 2017 and December 2018, 228 patients were finally included in the FAS analyses. The eradication rates were 74.1% for standard triple therapy (43/58, [95% CI: 62.8%‐85.5%]), 69.5% for sequential therapy (41/59, [95% CI: 57.8%‐81.2%] ), 89.8% for bismuth‐based quadruple therapy (53/59, [95% CI: 82.1%‐97.5%]), and 84.6% for concomitant therapy (44/52, [95% CI: 74.8%‐94.4%] ). Bismuth‐based therapy was superior to triple therapy, while sequential therapy and concomitant therapy were not superior to triple therapy. The frequency of adverse events was 12.1% (7/58) in standard triple therapy, 6.8% (4/59) in sequential therapy, 15.3% (9/59) in bismuth‐based therapy, and 15.4% (8/52) in concomitant therapy. The rate of adverse events was similar among the four groups. Conclusion Bismuth quadruple therapy can achieve an eradication rate of 89.8% as first‐line treatment and is safe and well tolerated. Bismuth could be a promising alternative as a first‐line regimen in Chinese children.
