Robert L. Kruse, Jennifer R. Kramer, Gia L. Tyson, Zhigang Duan, Liang Chen, Hashem B. El‐Serag, Fasiha Kanwal – 28 July 2014 – The effect of hepatitis B virus (HBV) coinfection in patients with hepatitis C virus (HCV) remains unclear. We used the National Veterans Affairs HCV Clinical Case Registry to identify patients with confirmed HCV viremia during 1997‐2005. We defined HBV coinfection as a positive test for hepatitis B surface antigen, HBV DNA, or hepatitis B e antigen.
