Replication Inhibition of Hepatitis B Virus and Hepatitis C Virus in Co-Infected Patients in Chinese Population

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infections contributes to a substantial proportion of liver disease worldwide. The aim of this study was to assess the clinical and virological features of HBV-HCV co-infection. METHODS: Demographic data were collected for 3238 high-...

Sumario:BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infections contributes to a substantial proportion of liver disease worldwide. The aim of this study was to assess the clinical and virological features of HBV-HCV co-infection. METHODS: Demographic data were collected for 3238 high-risk people from an HCV-endemic region in China. Laboratory tests included HCV antibody and HBV serological markers, liver function tests, and routine blood analysis. Anti-HCV positive samples were analyzed for HCV RNA levels and subgenotypes. HBsAg-positive samples were tested for HBV DNA. RESULTS: A total of 1468 patients had chronic HCV and/or HBV infections. Among them, 1200 individuals were classified as HCV mono-infected, 161 were classified as HBV mono-infected, and 107 were classified as co-infected. The HBV-HCV co-infected patients not only had a lower HBV DNA positive rate compared to HBV mono-infected patients (84.1% versus 94.4%, respectively; P<0.001). The median HCV RNA levels in HBV-HCV co-infected patients were significantly lower than those in the HCV mono-infected patients (1.18[Interquartile range (IQR) 0–5.57] versus 5.87[IQR, 3.54–6.71] Log(10) IU/mL, respectively; P<0.001). Furthermore, co-infected patients were less likely to have detectable HCV RNA levels than HCV mono-infected patients (23.4% versus 56.5%, respectively; P<0.001). Those HBV-HCV co-infected patients had significantly lower median HBV DNA levels than those mono-infected with HBV (1.97[IQR, 1.3–3.43] versus 3.06[IQR, 2–4.28] Log(10) IU/mL, respectively; P<0.001). The HBV-HCV co-infection group had higher ALT, AST, ALP, GGT, APRI and FIB-4 levels, but lower ALB and total platelet compared to the HBV mono-infection group, and similar to that of the HCV mono-infected group. CONCLUSION: These results suggest that co-infection with HCV and HBV inhibits the replication of both viruses. The serologic results of HBV-HCV co-infection in patients suggests more liver injury compared to HBV mono-infected patients, but is similar to HCV mono-infection.
