Helicobacter pylori infection in children: potential clues to pathogenesis (Journal article)

Children (227) undergoing endoscopy for upper gastrointestinal symptoms were investigated for the presence of Helicobacter pylori infection. The histological response to H. pylori infection and the presence of antral nodularity and peptic ulceration were noted. Symptomatic adults (258) undergoing endoscopy were also investigated for the presence of nodularity. H. pylori infection was detected histologically in 32 of 227 (14.1%) children. Of those children infected with H. pylori, half (50%) had antral nodular gastritis. Of 139 H. pylori-positive adults 22 (15.8%) showed nodularity. The active component of the histological response was found to be minimal or lacking in the majority of children infected with H. pylori. Twelve of the 227 children (5.3%) had peptic ulcer disease. Of these, nine were duodenal and three gastric ulcers. Of the nine children with duodenal ulceration three (33%) were infected with H. pylori. As a result of this study we conclude that (a) although antral nodularity occurs more frequently in children it is not exclusive to childhood, (b) the polymorphonuclear response in children is less than that reported in adults, and (c) peptic ulcer disease is rare in children and the present study would suggest that in children it is less frequently associated with H. pylori infection than in adults.
