“…The incidence of H. pylori infection in the general population varies with the geographic location and age and has been found to range from 10% to 57% [16,17]. The prevalence of H. pylori infection among bariatric patients undergoing gastric restrictive surgery was 24 -67% and was associated with a greater incidence of early postoperative foregut symptoms [18 -21].…”

“…data, 1996) that in patients with acute ulcer bleeding, the prevalence of H. pylori infection as diagnosed by using the CLO test was unexpectedly low and roughly similar to that reported by serology in healthy adults. 8 In addition, the low prevalence of H. pylori infection in bleeding Greek patients was found by others, 9 who also used the CLO test. Others reported significant false‐negative rates in patients with duodenal ulcer bleeding when the rapid urease test was used for the detection of H. pylori .…”

“…However, everywhere in the world, serological data have shown that the prevalence of the infection increases with age [5-7]. In particular in Greece, according to a study carried out in the early '90s [8] seroprevalence increased about 10% per 10 years, from 40% in people aged 21–40 years to 77% in those older than 60 years.…”

BackgroundTo evaluate changes in H pylori infection prevalence in Greece during a ten-year period, and to examine its antigenic profile.MethodsThree groups of patients were studied. Group O-87: Banked serum samples of 200 consecutive adult outpatients, from the Hepato-Gastroenterology clinic of a teaching hospital at Athens, collected in 1987. Group O-97: Serum samples of 201 similarly selected outpatients from the same Unit, collected in 1997. Group BD-97: Serum samples of 120 consecutive blood donors from the same hospital, collected in 1997. H pylori IgG antibody seroprevalence was studied by a quantitative ELISA. Antigenic profile was studied by western-blot IgG assay, in 62 IgG positive patients of O-97 and BD-97. Results were analyzed by conventional statistics and multivariate regression analysis.ResultsThe H pylori seroprevalence increased with age in the three tested groups. In O-97, seroprevalence did not differ from that, in BD-97. On the contrary, there was a significant decrease in seropositivity between O-87 and O-97 (59.5% vs 49.2%, p = 0.039). Multiple regression analysis showed that age over 35 years (OR:3.45, 95% CI:1.59–7.49, p = 0.002) and year of patients' selection – that is 1987 or 1997 – (OR:1.73, 95% CI:1.14–2.65 for 1987, p = 0.010), were independent risk factors of H pylori infection. The seroprevalence of CagA+ and VacA+ strains was 77.4% and 58.5%, respectively, and type I(CagA+/VacA+) strains were significantly more common than type II(CagA-/VacA-) strains (59.7% vs 22.6%, p < 0.001).ConclusionsDuring a ten-year period, we found a significant decrease of H pylori infection in Greece and our data support the birth cohort phenomenon as an explanation for the age-dependent increase of H pylori infection. The prevalence of CagA and/or VacA positive strains is relatively high, in a country with low incidence of gastric cancer.
