ABSTRACT
BACKGROUND: Helicobacter pylori (H. pylori) prevalence varies according to both geographical region and ethnicity. The interplay between these two factors has been poorly studied.
OBJECTIVES: To determine the positivity rate of H. pylori infection among Jewish and Arab patients who live in a mixed urban center in Israel.
METHODS: Between November 2009 and September 2014, dyspeptic patients referred to a gastroenterology clinic in Lod, Israel, were enrolled in a prospective study. For each patient, clinical and epidemiological data were collected and a noninvasive or endoscopy-based test for H. pylori was performed.
RESULTS: A total of 429 consecutive patients (322 Jewish and 107 Arabs), mean age 45 years (range 15-91 years) were included; 130 males. Overall positivity for H. pylori was 42.4% (182/429). The positivity rate of H. pylori was 38.8% for Jews (125/322) and 53.2% for Arabs (57/107) in Lod (P < 0.01). When immigrants were excluded, the difference in H. pylori positivity did not reach statistical significance (45.0% [77/171] vs. 53.2% [57/107], P = 0.217, in Jews and Arabs, respectively).
CONCLUSIONS: H. pylori infection was more common in Arabs that Jews in the mixed city of Lod, Israel. This finding may suggest that non-environmental factors were responsible for the observed difference in H. pylori positivity.
