title: [Nodular antritis and Helicobacter pylori infection in children].
abstract: We have studied 115 patients infected with Helicobacter pylori (HP). Endoscopic nodular antritis and histologic lymphonodular hyperplasia was noted. The frequency of nodular antritis was compared between the 115 HP patients and a HP-negative age-matched control group. Nodular antritis was observed in 70.4% of the HP-positive patients and 11.3% of the HP-negative group (p <0.001). The specificity of nodular antritis was 86.1%. A significant association was found between the existence of nodular antritis and histologic lymphonodular hyperplasia (67.9%; p < 0.001). In conclusion, the endoscopic nodular antritis is a frequent and specific finding in children with HP infection and is associated with histologic lymphonodular hyperplasia.
