Both Helicobacter pylori (HP) and hepatitis C virus (HCV) infections are endemic in Egypt. This work aimed to investigate the presence of HP in the liver of patients with chronic hepatitis C (CHC) and explore the relation between HP infection, liver histopathology and HCV viral load. The study included 60 patients with CHC. Virological, biochemical, liver biopsy and testing for anti-Hp and anti-schistosomal antibodies in serum were done. Liver tissues were examined for histopathological and presence of Hp by detection of HP 16S rRNA gene by PCR and sequence analysis. Anti-schistosomal and anti HP antibody was found in 45% and , respectively. Low stages of fibrosis (F0–F3) were found in and advanced fibrosis (F4–F6) in . HP DNA was found in 10% of the liver specimens. Although the frequency HP antibodies was equally high in patients with advanced and low fibrosis ( and , P > ), the HP DNA in liver tissue was significantly more frequent in patients with advanced fibrosis ( vs. , P = ). | Impact of Helicobacter pylori infection on liver fibrosis in Egyptian patients with chronic hepatitis C
