[Determination of antibodies to Campylobacter pylori in children and adolescents with gastroduodenal disorders].

Serological examination of antibodies against Campylobacter pylori was made in 195 boys and girls aged 9-20 years. In all on account of gastrointestinal complaints endoscopy was indicated. The results of microbiological and histological finding), in particular in the antrum and corpus of the stomach). Positive titres antrum and body of the stomach were compared with results of the complement fixation test and the ELISA reaction. Antibodies against C. pylori were detected in 64 of the examined subjects. The titres assessed by the complement fixation and ELISA test were in good agreement. Patients with positive sera had significantly more often a positive endoscopic finding (bacteria, chronic gastritis) and bacteriological finding), in particular in the antrum and corpus of the stomach). Positive titres of the complement fixation reaction persisted frequently for 15 months after the first examination. From the results ensues that serological examination of antibodies against C. pylori can be considered a sparing examination method which in patients with gastrointestinal complaints should precede endoscopic examination and moreover it can be used to follow up the course of the disease and success of therapy.
