the relationship between helicobacter pylori and lymphonodular hyperplasia of the stomach in children

association of helicobacter pylori with pathogenesis of gastrointestinal disorders (including gastritis in children with special endoscopic anteronodular) have significant importance in prognosis of infection resulting from this bacteria in children. however, in this research it was found that there is significant and clear correlation between nodular anteritis (in endoscopy) and active presence of lymphoid follicle (in histology findings with replacement of h.pylori) was noticed in children. in this research 14 persons (34.1%) out of total patients were positive. the average age of positive h.pylori patients was clearly higher than negative h.pylori patients. so increase of possible infection occurrence together with increase of age in children was confirmed. meanwhile, there is significant relationship between presence of bacteria and clinical symptoms particularly epigastric pain, vomiting, and nausea. one of the other results of this study was confirming the relationship between history of gastrointestinal disorders in immediate family members and infection resulting from h.pylori in patients.
