Recurrent abdominal pain (RAP) is a very common presenting complaint in pediatric population. There is still a debate regarding the role of Helicobacter pylori (H. pylori) infection as an etiology of RAR Typically the inflammatory process in the gastric mucosa of infected individuals is chronic gastritis. Serologic and histologic examination are widely used for the diagnosis. This study was aimed to determine the role of H.pylori infection in Indonesian children with RAR The presence of serum IgG antibody to H. pylori and upper gastrointestinal endoscopy were performed on the 101 children with RAR Mztcosal biopsies were obtained for histologic analysis. The prevalence of H. pylori infection indicated by serology was 32.7% and by histology was 27. 7%. Histologic evidence of gastritis was present in 94.1 % children and 45% of them had chronic atrophic and active gastritis. Seventy percent children with H. pylori positive were found abnormal through endoscopy and all of the infected children were revealed abnormal through histological examination. Forty eight percent of seropositive children were found H. pylori positive and 80% of seronegatives children were found to be H pylori negative through histologic examination. Conclusion: H. pylori infection can be a cause of RAP in children. Work up for H. pylori infection should be performed when symptoms are suggestive of organic disease. Larger prospective studies are needed to be perforated for a longer time of period to clarify this issue.
