Immune cell recovery post-HSCT in ATG-FRES (Fresenius) treated patients in comparison with high (ATG-GENZ-high) and low dose (ATG-GENZ-low) ATG-GENZ (Genzyme) treated patients. CD3 T-cell and CD4 and CD8 T-cell subset numbers differed significantly at one month post-HSCT between the two ATG treated groups. ATG-GENZ-high patients recovered significantly slower for CD3, CD4, and CD8 compared to the ATG-FRES and ATG-GENZ-low treated patients. In contrast to the T-cell recovery, NK-cells recovered fast after HSCT reaching normal levels within 1 month. The highest level of NK-cell numbers were observed at one month in the ATG-GENZ-high group. B-cell recovery in all ATG groups returned to normal levels at 6 months post-HSCT with a significantly higher number of B-cells at 2 and 3 months in the ATG-GENZ-high compared to the ATG-GENZ-low and ATG-FRES treated patients, respectively. Dotted horizontal lines represent the 5th and 95th percentiles of cell numbers in 28 healthy age-matched donors. Gray line: patients transplanted for acute leukemia with a graft from an HLA-identical sibling donor without receiving ATG in the conditioning.
