title: A study of Helicobacter-pylori in 100 pediatric patients from the Tri-State area.
abstract: Helicobacter pylori (HP) is a newly discovered pathogen implicated in the pathophysiology of peptic ulcer disease. The aim of this study was to review all pediatric patients who were evaluated by upper endoscopy through the Pediatric Gastroenterology Service at the Marshall University School of Medicine between July 1990 and March 1993. A total of 100 charts were retrospectively reviewed. HP was diagnosed by CLO-test and confirmed histologically. Results showed that the major presenting symptom was abdominal pain (53%). GI mucosal inflammation was found in 77 patients, and 41% of these cases were associated with HP. Two patients had duodenal ulcer; both were HP+. The incidence of gastritis was significantly higher in patients with HP+ compared to HP-. Follow-up on the HP-associated gastritis showed no significant difference in their clinical response irrespective to the treatment, we conclude that HP in children is highly associated with gastritis, but not duodenitis or esophagitis; and in our experience, that CLO has a high failure rate in identifying HP in the mucosa.
