Endoscopic and Histological Findings among Israeli Populations Infected with Helicobacter pylori: Does Ethnicity Matter?

Summary

Background:

The prevalence of Helicobacter pylori varies geographically by age, race, and socioeconomic status (SES). However, the impact of ethnicity on endoscopic outcomes in infected individuals is not well known.

Objectives:

To assess the impact of ethnicity among Israelis with biopsy-proven H. pylori infection.

Methods:

A retrospective study, including patients who underwent gastroscopy and were diagnosed histologically with H. pylori infection, was conducted. Information on demographics, SES, medications, and co-morbidities were extracted from medical records. Univariate (Student's t-test, chi-square test) and multivariate (multinomial and logistic) regression analysis were conducted to examine the predictors of the clinical outcome.

Results:

The study included 100 Israeli Jews and 100 Israeli Arabs diagnosed with biopsy-proven H. pylori infection. At univariate analysis, the number of households was higher among Arabs (P < 0.001), whose family income and parental education were lower than among Jews (P < 0.001 for both variables). The response to amoxicillin and clarithromycin differed between the two groups, being higher among Jews (P < 0.001).In clinical outcomes (gastritis severity, gastric and duodenal ulcer, intestinal metaplasia, atrophic gastritis, and MALT), no statistically significant differences could be detected between Jews and Arabs. Concerning intestinal metaplasia, lack of consumption of nonsteroidal anti-inflammatory drugs resulted a statistically significant protective factor (odds ratio 0.128, 95% confidence interval 0.024–0.685, P = 0.016).

Conclusions:

Although in the literature ethnicity seems to be a risk factor for H. pylori colonization, no statistical significance was detected in various endoscopic and histological findings related to H. Pylori infection between Israeli Arabs and Jews.
