Cytomegalovirus reactivation in patients with chronic lymphocytic leukemia treated with alemtuzumab: prophylaxis vs. pre-emptive strategies for prevention

Management of CMV, HHV-6, HHV-7 and Kaposi-sarcoma herpesvirus (HHV-8) infections in patients with hematological malignancies and after SCT

These recommendations were prepared by the European Conference on Infections in Leukaemia following a predefined methodology. Literature searches were made to identify studies pertinent to management of CMV, HHV-6, -7 and -8 infections. For CMV, 76 studies were reviewed: 72 published and 4 presented as abstracts. Twenty-nine of these studies were prospective randomized trials. For the other herpesviruses, HHV-6, -7 and -8, no randomized controlled trial has been performed, although data from some studies with other primary endpoints have been used to assess the management of HHV-6 infection. Works presented only as abstracts were used to a very limited extent. The quality of evidence and level of recommendation were graded according to the Center for Disease Control (CDC) criteria.
