Abstract:

Objective

To assess the relationship between Helicobacter pylori (Hp) infection and non-alcoholic fatty liver diseases (NAFLD).

Methods

Articles that examined the association between Hp infection and NAFLD were searched. The certain data were pooled with a random-effects model.

Results

Ten trials were included, among which, eight case-control studies were carried on a binary variables meta analysis. It was concluded that due to the significant heterogeneity which failed to be explained by subgroup analysis, it was unable to use a meta-analysis to explore the relationship between Hp infection and NAFLD. A single rate meta-analysis was carried out on the ten studies, it is concluded that Hp infection rate in patients with NAFLD was 47.7% (95%CI: 0.334-0.620), which had no significant difference from the rate of general population.

Conclusions

High quality trials were needed to furtherly explore the relationship between Hp infection and NAFLD.

Key words: Helicobacter pylori, Non-alcoholic fatty liver diseases, Meta-analysis
