ABSTRACT
Serum gastrin and pepsinogen concentrations were measured in 51 children infected with Helicobacter pylori, to investigate the clinical significance and influence of CagA and VacA on serum concentrations of these peptides. CagA+ was 44/51 (86%) and VacA+ was 42/51 (82%). Type I (CagA+/VacA+) included 39/51 (76%), type II (CagA-/VacA-) was 4/51 (8%), and intermediate (CagA-/VacA+, CagA+/VacA-) was 8/51 (16%). There was no significant correlation between endoscopic diagnosis and the state of CagA/VacA. Serum gastrin concentrations were not significantly correlated with the state of CagA/VacA. Serum pepsinogen I and II concentrations were significantly higher in CagA+ than in CagA-, but there was no significant difference between VacA+ and VacA-, Serum pepsinogen I/II ratio was not significantly correlated with the state of CagA/VacA. There was no significant difference between serum concentrations of gastrin, pepsinogen I and H. pylori phenotypes. However, pepsinogen II concentration was significantly higher in type I than type II. Pepsinogen I/II ratio was significantly lower in type I and intermediate than in type II. These findings suggest that CagA positively and phenotype of H. pylori could play a role in the development of upper gastrointestinal diseases in children.
