Typical clinical course of HBV reactivation in HBsAg-positive and HBsAg-negative/anti-HBc-positive individuals receiving chemotherapy. In HBsAg-positive patients, serum HBV DNA was undetectable at the time of peak ALT, instead, it peaked prior to ALT by around 2 weeks [Yeo et al. 2001]. In HBsAg-negative/anti-HBc-positive subjects, serum HBV DNA preceded elevated ALT by 12–28 weeks [Hui et al. 2006]. HBsAg seroreversion developed after rise in serum HBV DNA and before ALT elevation [Hui et al. 2006].
HBV, hepatitis B virus; HBsAg, hepatitis B surface antigen; ALT, alanine transaminase.
