Abstract

Purpose: Helicobacter pylori infections differ between children and adults. The Pediatric society practice guidelines recommend against a test-and-treat approach, characterized by the use of non-invasive tests for diagnosis (e.g. urea breath test [UBT] or stool antigen test). However, significant variations exist in clinical practice. This study examined the use of non-invasive testing for the screening and diagnosis of H. pylori infection in children at a tertiary pediatric hospital in Singapore, reviewing both management decisions and patient outcomes. Methods: A retrospective review was conducted on children between the ages of 0 and 18 years who were tested for H. pylori infection using either a stool antigen test or UBT between January 2018 and June 2020. Results: Among the 1,397 children tested, 117 (8.4%) had a positive stool H. pylori antigen result, and 5 out of 85 tested (5.9%) had a positive UBT. Abdominal pain was the predominant symptom (n=98; 80.3%). Only 7 treatment-naïve children had biopsy-proven disease. Tissue biopsies for H. pylori culture were sent to 2 children, with 1 negative result. A total of 111 children (91.0%) received treatment, wherein proton pump inhibitor, amoxicillin, and clarithromycin for 14 days was the most common therapeutic regimen. Symptom resolution was observed in 62 children (50.8%). Conclusion: A test-and-treat strategy was more widely utilized than endoscopy-based testing, showing a low compliance to existing guidelines for the management of H. pylori infections in children at our center and significant false-positive rates.
