Helicobacter pylori is not associated with nonspecific abdominal pain in children

Nonspecific abdominal pain is a significant problem in the pediatric population, and there has been much recent interest in the role that Helicobacter pylori (HP) might play in this disorder. A retrospective review was conducted at our center to determine its prevalence among children with otherwise undiagnosed abdominal pain. The study was conducted over a 45- month period during which 47 patients underwent gastroscopy and antral biopsies in the workup of this problem. Of the 37 patients who did not have a history of acid-pepsin disease (APD), only one (2.7%) tested positive for HP. In contrast, of the 10 who had a history of APD, three (30%) tested positive (P < .03). There were no distinguishing features among the HP-positive patients except for the presence of associated antral gastritis. Based on the current endoscopic results, of the nine patients with current evidence of APD, four (44%) were positive for HP; of the other 38 patients, none was positive for HP. Therefore, HP appears to be associated with antral gastritis, and HP does not play a role in nonspecific abdominal pain in this population.
