ABSTRACT
The report describes a case of a four-month-old infant, who developed acute gastric ulcer while being hospitalised because of pneumonia. One year's observation of the patient, additional tests, especially gastroscopy with histopathological evaluation of biopsy specimen, determination of gastrin level in blood serum, and therapy analysis allow to establish a diagnosis of pseudo Zollinger-Ellison syndrome.

BACKGROUND: The aim of this study was to assess the correlation between the prevalence of Helicobacter pylori strains possessing cytotoxin-associated gene A (cagA) in children and the intensity of clinical complaints and morphological changes of the gastric mucosa. MATERIALS AND METHODS: A group of 80 children with gastrointestinal complaints was included in this study. Pathologists examined mucosal biopsy specimens from these patients. The urease test and multiplex polymerase chain reaction (MPCR) were used to identify H. pylori strains. RESULTS: In the group of children infected with cagA-positive H. pylori strains, fourth-degree gastritis was more frequent than in the group with cagA-negative H. pylori colonization. In histopathological assessment, infection with cagA-positive H. pylori was associated also with higher grades of inflammatory intensity and activity. CONCLUSIONS: Marked inflammation of the antral mucosa was significantly more frequent in children infected with cagA-positive H. pylori than in those infected with cagA-negative H. pylori, as assessed endoscopically and histopathologically. No specific symptoms for cagA-positive and cagA-negative H. pylori infection were observed.
