To assess the kinetics of lymphocyte subset recovery, 758 allografted patients were monitored by surface markers (CD3, CD4, CD8, CD56), with a 5-year follow-up. The donor was a matched sibling donor (MSD) (n=502) or an alternative donor (family mismatched or unrelated, AD) (n=256). The stem cell source was bone marrow for all patients. CD4+ cell recovery was influenced—in univariate analysis—by three factors: donor type, patient age and GvHD. This was not the case for CD8+ and CD56+ cells. The median CD4+ cell count on day +35 after HSCT was 86/μl. Patients achieving this CD4+ cell count had significantly lower transplant-related mortality (TRM) compared to patients who did not achieve this CD4+ cell count (20 vs 39%, P=0.00001), due to a lower risk of lethal infections (24 vs 47%, P=0.0003). In multivariate analysis MSD (RR 3.45, P=0.0001) and recipient age less than 16 years (RR 3.23, P=0.003) were significantly associated with a better CD4+ cell recovery. CD4+ counts on day +35 was predicted TRM (RR=1.97, P=0.0017) together with acute GvHD grade II–IV (RR 1.59, P=0.0097). No difference of TRM was observed for CD8+ and CD56+ cell counts.Bone Marrow Transplantation (2008) 41, 55–62; doi:10.1038/sj.bmt.1705870; published online 15 October 2007 [ABSTRACT FROM AUTHOR]
