ABSTRACT
Background:
Helicobacter pylori (Hp) infection occurs in about half of the world's population, and Hp eradication therapy is an important method for treating Hp infection-related diseases.Aims:
To explore the major shifts in gut microbiota before and after Hp eradication by using bismuth-containing quadruple therapy.Methods:
Fifty Hp-positive patients in whom the Hp was successfully eradicated by bismuth-containing quadruple therapy from January 2016 to January 2017 at the Third People's Hospital of Shenzhen were enrolled. Using genus-specific primers and genomic DNA extracted from the fecal samples collected before and within 3 days after eradication therapy, a quantitative analysis of the major shifts in gut microbiota was accomplished by real-time PCR.Results:
Compared with those before Hp eradication, fecal Enterobacterium and Enterococcus were significantly increased and Bifidobacterium, Bacteroides, Clostridium and total bacteria were significantly decreased after Hp eradication (P0.05).Conclusions:
Eradication of Hp infection by bismuth-containing quadruple therapy may cause changes in gut microbiota composition and resulting in dysbiosis.
