Helicobacter pylori infection in asymptomatic subjects in Benghazi , Libya

To determine the seroprevalence of Helicobacter pylori (H. pylori) antibodies in asymptomatic healthy population. Convenient sampling was done in asymptomatic healthy individuals accompanying the patients who had no previous history of epigastric pain. Venous blood was collected from individuals and sera separated. Enzyme-linked immunoflurescent assay (ELFA) was used to determine H. pylori IgG antibodies in all sera. A total of 79 samples were collected. H. pylori antibodies were found in 43 (54.4%) individuals. A 55.8 % seroprevalence was found in subjects 20 < 35 years of age, which gradually decreased with age and reached to 11.6 % in subjects up to 65 years of age. There was no significant association between presence of H. pylori antibodies and gender, marital status, dietary habits and sources of drinking water but relation with education level and wash hands was significant. Infection with H. pylori is prevalent in the healthy individuals of Benghazi, Libya. Infection is acquired in the early age and continues as the age advances. A nationwide epidemiological study is warranted to determine the seroprevalence of H. pylori in Libya.
