[Antibodies to H+/K+-ATPase of gastric parietal cells in children with Helicobacter pylori associated chronic gastritis].

54 children at the age of 3-15 suffering from HP-associated CG were examined. Antibodies to H+/K(+)-ATPase of gastric parietal cells were determined with the help of the immune-enzyme analysis method. It was discovered that antibodies to H+/K(+)-ATPase are found in 27.7% of children. Concomitant autoimmune diseases, pangastritis, morphologic symptoms of the pre-atrophic stage of autoimmune gastritis as well as the drop of secretion at the fasting phase were discovered more often in antibody-positive patients. The successful eradication of HP in two children resulted in the disappearance of anti-parietal autoantibodies.
