title: Kaposi's sarcoma-associated herpesvirus (KSHV/HHV-8) DNA sequences are absent in leukapheresis products and ex vivo expanded CD34+ cells from multiple myeloma patients.
abstract: Recently it was reported that Kaposi's sarcoma-associated herpesvirus (KSHV/HHV-8) infects bone marrow (BM) dendritic cells (DC) in multiple myeloma (MM) patients and therefore might play a role in MM development. Because of the use of myeloid growth factors like GM-CSF and G-CSF for the mobilization of peripheral blood progenitor cells (PBPC), the subsequent increase of DC precursors might imply a risk for KSHV contamination in PBPC grafts. Therefore, in this study leukapheresis products and ex vivo cultured CD34+ cell suspensions were analysed. KSHV DNA could not be amplified in any of them.
