Moroccan Children With Helicobacter pylori Infection: Demographics, Clinical Features, and Histological Findings

Area of Science:

• Gastroenterology
• Pediatric Infectious Diseases
• Microbiology

Background:

• Helicobacter pylori (H. pylori) infection affects nearly half the global population, contributing to peptic ulcers and gastric adenocarcinoma.
• Previous research has explored H. pylori associations with various factors in pediatric populations.
• This study focuses on characterizing H. pylori infection specifically within Moroccan children.

Purpose of the Study:

• To describe the epidemiological and clinical characteristics of H. pylori infection in Moroccan children.
• To investigate the association between H. pylori infection and histopathological findings in pediatric gastric biopsies.
• To identify potential risk factors and clinical manifestations of H. pylori in the pediatric population of Morocco.

Main Methods:

• A cohort of 213 children (aged 1-17 years) underwent upper gastrointestinal endoscopy.
• Gastric biopsies were collected from the antrum and corpus for H. pylori detection via Giemsa stain.
• Demographic, clinical, endoscopic, and histopathological data (including Sydney System gastritis scoring) were systematically recorded.

Main Results:

• H. pylori infection was detected in 95 (45%) of the pediatric participants, with infection rates increasing with age.
• A significant association was observed between H. pylori infection and nodular gastritis (p<0.05).
• The majority of infected children (98%) exhibited chronic inflammation, with 22% showing active inflammation and 47% displaying atrophy, generally mild in severity.

Conclusions:

• Nodular gastritis and non-specific symptoms are associated with H. pylori infection in Moroccan children.
• The link between H. pylori infection and gastric atrophy necessitates ongoing mucosal surveillance in affected children.
• Identifying factors contributing to gastric cancer risk in this population requires further investigation.
