Helicobacter pylori has become very important recently due to infecting around 50% of the population worldwide. This infection can cause peptic ulcer disease and gastric cancer. This study aimed to evaluate the efficacy of common triple treatment, sequential treatment, and other regimens for Helicobacter pylori eradication in children.
Materials and Methods: In this retrospective cohort study, 40 children who were diagnosed with Helicobacter pylori infection by endoscopic and pathologic features in the Children’s Medical Center of Tehran, Iran, in 2018 were included. The questionnaire was completed by telephone interview. Types of protocols include triple therapy (proton pump inhibitors with clarithromycin and amoxicillin or metronidazole for 2 weeks), sequential therapy (proton pump inhibitors with amoxicillin for 5 days followed by proton pump inhibitors with clarithromycin and metronidazole for 5 days), and other treatments (every protocol except triple and sequential regimens). At the end, we compared the efficacy of the different protocols for eradicating this infection by urea breath test or stool antigen test 8 weeks after therapy.
Results: The age of patients with and without successful eradication was 8.12 and 7.8 years, respectively (p=0.8). There was no significant difference between both sexes (p=0.999) in the frequencies of eradication. The eradication rate of Helicobacter pylori was 95.5% in sequential therapy, 100% in conventional triple therapy, and 87.5%in other regimens. There was no significant difference between different protocols (p=0.422).
Determining first-line treatment for eradicating Helicobacter pylori infection is important to increase treatment success and reduce rate of secondary antimicrobial resistance. Our study showed that sequential treatment is as effective as conventional treatment in eradication of this infection in children.
