2 Figure 1 Neutropenia after alemtuzumab/TBI conditioning in adult SCD patients. Neutrophil counts after conditioning with alemtuzumab/total body irradiation and hematopoietic stem cell transplantation. Each value represents the mean neutrophil count ± standard error (n = 13).

3 Figure 2 Engraftment analysis after alemtuzumab/TBI conditioning in adult SCD patients. Whole blood mononuclear cell (MNC) and CD3+ lymphoid cell chimerism values at day +90, day +180, and day +365 after hematopoietic stem cell transplantation (HSCT) in the 12 patients with stable engraftment.

4 Figure 3 Normalization of hemoglobin after alemtuzumab/TBI conditioning in adult SCD patients. Hemoglobin fractionation studies and total hemoglobin concentrations after hematopoietic stem cell transplantation in 12 patients with stable engraftment. (A) The proportion of hemoglobin A in the recipients was stable and consistent with the proportion observed in the donor. (B) Mean hemoglobin concentrations ± standard errors by sex of recipient.

5 Figure 4 Cardiopulmonary improvement after alemtuzumab/TBI conditioning in adult SCD patients. Cardiopulmonary improvement at 1 year post-hematopoietic stem cell transplantation was observed in 12 patients with stable engraftment. (A) Brain-natriuretic peptide (BNP) concentrations, (B) Left atrial diameter, (C) Forced expiratory volume at 1 second (FEV1), and (D) Forced vital capacity (FVC) measurements are given as mean values ± standard error.

6 Figure 5 Rapid and sustained improvement in the HRQoL after HSCT in adult SCD patients. Improvements in normalized HRQoL scores and SF-6D scores between before and after HSCT in 9 patients with stable engraftment. (A) SF-36 mean scores ± standard error across the eight HRQoL domains. Differences between pre- and post-HRQoL scores were analyzed and P values are shown. (B) SF-6D mean scores ± standard error at each time point of assessment. Δ > .033 represents the commonly accepted minimally important difference.
