H. pylori was isolated from biopsies from 50/100 (50%) adult patients undergoing endoscopy for investigation of upper gastrointestinal tract symptoms. Urease was detected in biopsies from 54 patients and gastritis was detected by histology in 71 patients. Serology was performed using a commercial ELISA method. Using an IgG concentration of 10 U/ml as a threshold, antibodies were detected in 78% of 100 patients undergoing endoscopy, 72% of 230 blood donors and 22% of 50 children. The mean antibody concentration was significantly higher in patients (92 U/ml) than in blood donors (49 U/ml) or in children (9.5 U/ml). Culture-positive patients (120 U/ml) had higher IgG concentrations than culture-negative patients (64 U/ml). Using isolation of H. pylori or a positive biopsy urease test as a measure of true prevalence of infection, the sensitivity of serology was 96%, the specificity 42%, pos...

Two different epidemiological patterns can be distinguished: one concerning the industrialized countries where an increased prevalence of infection with age is noted and the other found in the developing countries where the majority of young people are already infected when they reach adulthood, the prevalence ranging from 60 to 90% in all age groups. Poland, like most of the Eastern European countries, represents an overall infection rate of 73% and the infection rate for the subjects over 25 years of age of 85-95%. The infection rate observed in the developed countries reflects a so called cohort effect, i.e., a change in the incidence of infection according to generation or age cohort due to changes in socioeconomic conditions. The infection rate observed in the developing countries is mainly determined by a high rate of incidence of this infection in childhood. The risk factors of H. p...
