Helicobacter pylori Infection Is Associated With Low Serum Ferritin Levels in Israeli Arab Children—A Seroepidemiologic Study

Abstract
We examined the association between Helicobacter pylori seropositivity and low ferritin levels in sera of 509 Israeli Arab children aged 1 to 19 years. Serum ferritin levels were measured using the immunoturbidity assay. ELISA was used to detect serum IgG antibodies to H pylori and IgG antibodies to H pylori CagA strains. Low ferritin level was found between 14.5% and 8.6% of the H pylori seropositive and seronegative participants, respectively (P = 0.035). A trend for a higher frequency of low ferritin was detected among H pylori-CagA seropositive children. Multivariate analysis showed an increased frequency of low ferritin only among children younger than or equal to 5 years: adjusted OR 4.62 (95% CI 1.53-13.99) P = 0.007.
