Diagnostic and Treatment Practices for Helicobacter Pylori Infection in an Academic Pediatric Hospital

In 2016, ESPGHAN/NASPGHAN issued revised guidelines for the management of Helicobacter pylori (H. pylori) infection in children and adolescents. Recommendations include performing antibiotic susceptibility testing to tailor therapy. The aim of our study was to evaluate the H. pylori treatment landscape in pediatric patients at our institution. We performed a retrospective study of patients diagnosed with H. pylori infection at a single academic children's hospital from 2015 to 2021. The frequency of each treatment regimen and their respective eradication rates were calculated. We compared trends in antibiotic prescriptions and eradication rates before and after 2016. One hundred and ninety-six patients were included. Triple therapy with amoxicillin, clarithromycin, and a proton pump inhibiter (PPI) was the most often prescribed regimen (46.5%), followed by amoxicillin, metronidazole, and PPI (33%). Eradication rates were 70% for amoxicillin, clarithromycin, and PPI and 64% for amoxicillin, metronidazole, and PPI. Our results show eradication rates for both regimens were comparable but suboptimal, highlighting the need to incorporate resistance testing into broader practice.
