Blood lead level and Helicobacter pylori infection in a healthy population: A cross-sectional study.

Blood lead level and Helicobacter pylori infection in a healthy population: A cross-sectional study. Arch Environ Occup Health. 2019 Aug 20;:1-6 Authors: Park WJ, Kim SH, Kang W, Ahn JS, Cho S, Lim DY, Kim S, Moon JD Abstract The aim of this study was to investigate whether elevated blood lead level (BLL) is a risk factor for Helicobacter pylori infection. Upper gastrointestinal endoscopy was performed on 2,625 subjects who visited a university hospital for general health examination. H. pylori infection was detected using histologic examination with Giemsa staining, and BLLs were measured. The mean BLL was 2.83 ± 1.31 μg/dL. The prevalence of H. pylori infection was 27.8%. The BLL was significantly higher in the H. pylori infection-positive group compared to the non-infected group (2.96 ± 1.33 μg/dL vs. 2.78 ± 1.30 μg/dL, p < 0.001), which remained significant after adjusting for other confounders. H. pylori infection significantly increased as the BLL increased (OR: 1.143, 95% CI 1.068-1.223). We found a relationship between BLL elevation and H. pylori infection rate.
