Vitamin D status and Helicobacter pylori infection: clinical associations and lipid pathway differences in an exploratory metabolomics sub-study (opens in new tab)

BackgroundVitamin D has immunomodulatory functions, and lower serum levels have been associated with increased risk of chronic infections, including Helicobacter pylori. We evaluated the association between vitamin D status and H. pylori infection and explored vitamin D–associated metabolic differences in an exploratory untargeted metabolomics sub-study.MethodsThis cross-sectional study enrolled 502 unrelated Lebanese adults (323 females, 179 males). Demographic, clinical, and biochemical var...
