Hepatitis B virus among hematopoietic stem cell transplant recipients: Antiviral impact in seroconversion, engraftment, and mortality in a Latin American center.
Hepatitis B virus (HBV) infection is a worldwide concern with a broad distribution. In immunosuppressed populations, such as solid organ and hematopoietic stem cell transplant (HSCT) recipients, it can reactivate leading to acute hepatic failure. Different risk factors are known for higher rates of reactivation, and entecavir, tenofovir, and lamivudine are often used for prophylaxis and treatment. However, data regarding the impact of antiviral drugs in neutrophil and platelet engraftment are still unknown and concern the management of viral hepatitis post-HSCT. ⋯ To sum up, HBV serology, ALT, and HBV-DNA monitoring are essential to detect hepatic flares earlier, even in populations with chronic inactive hepatitis, due to the possibility of later seroconversion. HBV infection was not related to increased 2-year mortality post-transplant. Antiviral prophylaxis did not cause any important clinical or laboratory side effects that could demand discontinuation, and its use was not associated with later neutrophil and platelet engraftments.
