Despite anti-thymocyte globulin has a mainstay role in preventing GvHD (and non-relapse mortality) in CB transplantation, it also induces delayed immune recovery, increased risk of cytomegalovirus and Epstein-Barr virus reactivation, post-transplant lymphoproliferative diseases, overall accounting for increased transplant-related mortality and/or increased relapse incidence. All these findings support the use of alternative approaches for in vivo T cell depletion in the setting of CB transplantation.
