Hepatitis B Reactivation (891)
Warning
Hepatitis B virus reactivation (HBVr) refers to the abrupt increase in hepatitis B virus in patients with minimally active or resolved/cleared HBV infection. The loss of HBV immune control can lead to an increase in or the reappearance of HBV DNA and a rise in ALT. Liver damage due to HBVr may occur during immunosuppression and/or following immune reconstitution. HBVr may be subclinical or rarely may progress to liver failure or death despite antiviral therapy.
