Abstract
-
Two cases of human herpesvirus-6 (HHV-6) encephalitis that occurred after allogeneic hematopoietic stem cell transplant (HSCT) are presented. Both patients reported fever, skin rashes, and neurological symptoms, characterized by disorientation, confusion and drowsy mental status. HHV-6B DNA was detected from the cerebrospinal fluid (CSF) specimens by a multiplex polymerase chain reaction (PCR) assay including EBV, CMV, HHV-6B. After treatment with intravenous gan ciclovir for 2~3 weeks, all clinical manifestations were resolved and the HHV-6B DNA was cleared from the CSF in both patients. HHV-6 should be considered as a possible cause of neurological symptoms after HSCT, and prompt antiviral treatment should be begun.
