We examined the prevalence and correlates of Helicobacter pylori (H. pylori) infection according to cytotoxin-associated gene A (CagA) phenotype, a main virulence antigen, among the ethnically diverse population groups of Jerusalem. A cross-sectional study was undertaken in Arab (N = 959) and Jewish (N = 692) adults, randomly selected from Israel's national population registry in age-sex and population strata.

- The study aimed to explore the prevalence of atrophic gastritis, a condition linked to gastric cancer, in two populations: Jews and Arabs in Israel.
- Using serum tests on a sample of nearly 700 Jews and 950 Arabs, results showed that Arabs had a higher prevalence of atrophic gastritis (8.8%) compared to Jews (5.9%).
- The association with the CagA infection was different for each group, revealing that it increased the risk in Jews but decreased it in Arabs, and women were generally more affected than men.
Associations observed of Helicobacter pylori infection with haemoglobin levels are inconsistent. We examined associations of H. pylori sero-prevalence and serum pepsinogens (PGs), as non-invasive markers of atrophic gastritis, with haemoglobin levels.

Additionally, we determined the prevalence of clarithromycin resistance and cagA gene in H. pylori-positive samples.
