title: Infections with human herpesvirus 6 variant B delay platelet engraftment after allogeneic haematopoietic stem cell transplantation.
abstract: The clinical significance of human herpesvirus (HHV-6) infections after allogeneic stem cell transplantation (SCT) remains controversial. We analysed cryoconserved plasma samples from 82 patients after allogeneic SCT by quantitative polymerase chain reaction for HHV-6 variants A and B. Platelet engraftment was delayed in patients with HHV-6B infections but not with HHV-6A infections detected before day +28. In multivariate analysis early HHV-6B infections and the type of conditioning were associated with platelet engraftment. In conclusion, the two variants of HHV-6 should be studied separately; early infections with HHV-6B may contribute to delayed platelet engraftment after allogeneic SCT.
