Abstract

We evaluated immune reconstitution in 58 adults who received hematopoietic SCTs from allogeneic siblings (allosib), matched unrelated donors (MUD) or cord blood (CB) at 90-day intervals for 1 year post transplant. CB recipients had a higher incidence of infections in the first 100 days compared with allosib and MUD recipients. The number of circulating T cells was lower in CB recipients compared with MUD recipients at 90 days and compared with allosib recipients at 180 days. Spectratype analysis of the TCR Vβ complementarity determining region 3 (CDR3) of patient lymphocytes revealed that the TCR repertoire remained poorly diversified even at 360 days in nearly all patients. In contrast, the number of circulating B cells was significantly elevated in CB recipients compared with allosib recipients throughout the first year post transplant and compared with MUD recipients at 9-12 months. Spectratype analysis of the B-cell receptor V(H) CDR3 showed that the B-cell repertoire was diversified in most patients by 90 days. CD5(pos) B cells from assayed CB recipients expressed intracellular IL-10 early post transplant. Our data suggest that B cells, in addition to T cells, may have a role in impaired immune responses in CB transplant patients.
