A survey of allogeneic bone marrow transplant programs in the United States regarding cytomegalovirus prophylaxis and pre-emptive therapy.

摘要

Despite an extensive literature, no consensus has emerged regarding the optimal preventive strategy for CMV in allogeneic bone marrow transplantation (BMT). No survey of CMV prevention in BMT centers in the United States has yet been published. A questionnaire was sent to all allogeneic BMT programs in the United States, as listed in the November 1998 National Marrow Donor Program (NMDP) address roster. Questions included whether universal prophylaxis, pre-emptive therapy, or some other strategy was used for CMV prevention, and which CMV diagnostic tests were utilized. Eighty-one of 96 programs (86%) responded to the survey. Of these, 46 (56%) utilize a pre-emptive ganciclovir strategy, whereas 17 (21%) utilize universal prophylaxis, and 15 (19%) utilize a hybrid strategy based on risk stratification. The most commonly utilized CMV diagnostic tests are CMV-DNA by PCR (55 centers), shell vial centrifugation culture (52), tissue culture (42), pp65 antigenemia assay (38), and CMV-DNA by Digene hybrid capture (14). Of these, the CMV-DNA by PCR, pp65 antigenemia assay, and shell vial culture are the most frequently utilized as triggers for pre-emptive therapy. Quantitative assays are common (PCR 42%, Digene 64%). We conclude that centers currently performing allogeneic BMT in the United States employ a variety of strategies for CMV prevention, and differ in their diagnostic tests of choice for CMV monitoring. These results emphasize the need for large-scale studies to identify optimal diagnostic and management protocols. Bone Marrow Transplantation (2000) 26, 763-767.
