title: [Serological profile of Helicobacter pylori infection in the population of San Luis (Argentina)].
abstract: We performed a seroepidemiological study of anti-Helicobacter pylori IgG by a commercial enzyme immunoassay kit (Meridian Diagnostics, USA) in 509 serum samples from 314 randomly selected asymptomatic subjects from among the population, and grouped into children (n = 124), adolescents (n = 74) and adults (n = 116), and in 195 serum samples from subjects presenting clinical gastric symptoms, grouped into children (n = 38) and adults (n = 157). The cut-off value was redefined and set at OD450 = 0.050. The percentage of seropositive individuals was not significantly different between the two groups of adults studied (75.9% and 80.2%, respectively) (p < 0.05), suggesting a high degree of contact with the microorganism in this region.
