The role of Helicobacter pylori in recurrent, functional abdominal pain in children.
Recurrent abdominal pain in children usually is considered to be functional in nature. We hypothesized that Helicobacter pylori infection might be the etiology of abdominal pain symptoms in some children with presumed functional abdominal pain. Therefore, we studied 20 children with a previous diagnosis of functional abdominal pain, using a 13C-urea breath test and an enzyme-linked immunosorbent assay for antibody to the H. pylori high molecular weight, cell-associated antigens. Two children had evidence of H. pylori infection, and both had clinical histories that suggested an acute H. pylori infection, at the onset of their abdominal pain. Seven children who had abrupt onset of their chronic abdominal symptoms were then identified prospectively. None of these patients had evidence of active H. pylori infection. We conclude that H. pylori infections are not common among children with recurrent abdominal pain, and are not predictable in such children, based on symptom patterns.
