Samenvatting

In vivo T-cell depletion might contribute to the delayed immune reconstitution observed after unrelated umbilical cord blood transplantation (UCBT). We studied the impact of early, late, and no antithymocyte globulin (ATG) on immune reconstitution and outcome. One hundred twenty seven children receiving UCBT in London or Utrecht were divided into 3 groups: early ATG (days 29 to 25; n 5 33), late ATG (days 25 to 0; n 5 48), and no ATG (n 5 46). The no-ATG group received mycophenolate mofetile 1 cyclosporin A as graft-versus-host disease (GVHD) prophylaxis, while the ATG groups received cyclosporin A 1 prednisone. End points studied were survival, immune recovery, infections, and GVHD. The probability of survival was similar in all groups: no ATG, 71% ± 8%; early ATG, 68% ± 9%; and late ATG, 61% ± 7%. CD31, CD41, and CD41-naive T-cell counts were significantly higher (P < .001) in the no-ATG group at 1, 2, 3, 6, and 12 months post- UCBT. In the no-ATG group, significantly fewer viral reactivations (P 5 .021) were noted. A higher probability of severe acute GVHD (aGVHD; 31%) was found in the no-ATG group compared with 18% (P 5 .018) for early-ATG and 5% (P < .001) for late-ATG groups. This was not associated with more chronic GVHD (cGVHD). (Blood. 2014;123(1):126-132).
