The Effectiveness of a Sequential Helicobacter Pylori Eradication Regimen on the Severity of Clinical Symptoms in Children with Chronic Gastritis: A Randomized Clinical Trial

Background: The effectiveness of eradicating Helicobacter pylori infection in improving the symptoms of chronic gastritis has been examined; however, the results of the studies have been contradictory, especially in childhood. This study aimed to compare the clinical effectiveness of sequential Helicobacter pylori eradication treatment and proton pump inhibitor alone in children with chronic Helicobacter pylori-positive gastritis.Methods: This randomized double-blinded clinical trial was conducted on ۸۴ children aged ۵ to ۱۵ years suffering from Helicobacter pylori-associated active chronic gastritis. The patients in the experimental group received sequential therapy including omeprazole, amoxicillin, clarithromycin, and metronidazole; and those in the control group only received omeprazole. Before the intervention, and ۲ and ۴ months after it, the severity of clinical symptoms was assessed.Results: After therapeutic regimens, the intervention group was found to have a significantly higher decrease in the severity grades of some symptoms including heartburn, gastroesophageal reflux, and abdominal pain in the epigastric area as compared to the control group (P<۰.۰۵). The assessment of the frequency of clinical symptoms in the intervention and control groups also indicated a greater reduction in epigastric pain in the group treated with Helicobacter pylori eradication as compared to the control group (P<۰.۰۵).Conclusion: Prescribing a sequential Helicobacter pylori eradication regimen can lead to reducing the severity of clinical symptoms in children suffering from chronic gastritis.
