[ Summary ] |
Reactivation of the hepatitis B virus (HBV) is common following chemotherapy and is associated with high mortality rates despite prompt anti-vairal treatment. Consequently, prophylactic anti-viral treatment is recommended for HBsAg-positive patiens before chemotherapy or immunosuppressive treatment. Recently, HBV reactivation related to newer therapeutic regimens, such as rituximab (anti-CD20)-plus-CHOP has been increasingly reported. HBV reactivation also occurs in patients in posthepatitis B status (negative for HBsAg and positive for HBcAb and/or HBsAb). This condition is associated with a higher risk of fulminant failure with a mortality rate of 100%. We proposed guidelines for screening and preemptive anti-viral treatment for patients at risk. Pre-treatment anti-HBc and anti-HBs testing should be performed in HBsAg-negative patients, especially those receiving rituximab plus steroid-containig regimens. Furthermore, anti-HBc positive and/or anti-HBs positive patients should be monitored for detectable increases in serum HBV DNA during and after completion of chemotherapy. This will facilitate prophylactic commencement of nucleoside analogs. |
