Abstract
Over a one-year period, 95 children and adolescents presenting with epigastric pain and/or vomiting, and without associated risk factors for development of peptic disease, underwent endoscopic antral biopsies for pathologic diagnosis and to detect presence of Campylobacterss. pylori (C. pylori). Additional biopsies of the esophagus, stomach, and duodenum were obtained for histologic evaluation. C. pylori was identified in 16 patients (16.8%), all of whom had evidence of acute and/or chronic gastritis. Significant discriminating factors between C. pylori-positive and -negative subjects included age at presentation (positive vs negative=14.6 vs 9.9 years, P2-receptor antagonists, antacids). Symptomatic and histologic remission was achieved utilizing combined therapy with bismuth subsalicylate and antibiotics. Seven of 79 C. pylori-negative patients with biopsyproven gastritis who responded poorly to antisecretory therapy had the organism identified in follow-up antral biopsies; these patients improved clinically following treatment for C. pylori. These data suggest that C. pylori is a significant factor in the etiology of upper gastrointestinal tract inflammatory disease in pediatrics, and presence of the organism should be evaluated, particularly in children with evidence of acute and/or chronic gastritis.
