• Cord blood (CB)
• stem cell transplant
• engraftment kinetics
• double cord blood units

We retrospectively evaluated neutrophil engraftment kinetics in 29 single versus nine double unit cord blood transplants (CBTs). All single CBTs were performed in pediatric patients (non-malignant/malignant diseases, 19/10), while all double CBTs were performed in adults (n aEuroS== aEuroS8) and an adolescent (n aEuroS== aEuroS1) with hematological malignancies. Median follow-up time was 2.3 years (range, 0.1--13.5 years). Engraftment was achieved in 69%% and 89%% of the single and double cord blood (CB) groups, respectively. Similarly, median day of engraftment was not different for the single versus the double CBTs, at 19 and 23 days, respectively, and the neutrophil engraftment kinetics was similar in the two groups. Our data indicate that adults without sufficient nucleated cell doses in a single CB unit may receive two units with similar engraftment kinetics to those of children receiving only a single unit.</.
