1 Nonmyeloablative Peripheral Blood Haploidentical Stem Cell Transplantation for Refractory Severe Aplastic Anemia  Jennifer Clay, Austin G. Kulasekararaj, Victoria Potter, Francesco Grimaldi, Donal McLornan, Kavita Raj, Hugues de Lavallade, Michelle Kenyon, Antonio Pagliuca, Ghulam J. Mufti, Judith C.W.

2 Figure 1 (A) Patient 6. Changes in HLA antibody levels as measured by the mean fluorescence index (MFI). Recipient and donor HLA typing are shown in the table at the bottom. Before HSCT, this patient had multiple class I HLA antibodies, of which only HLA-B51 was donor directed. After intensive plasma exchanges and rituximab, the antibody level fell from a peak of 7946 MFI to 1304 immediately pre-HSCT. PEX indicates plasma exchange. (B) Patient 8. Changes in HLA antibody levels as measured by MFI. Recipient and donor HLA typing are shown in table at the bottom. Pretransplant, this patient had class I and II HLA antibodies, all of which were donor directed: HLA-B45, -DR7, -DQ2, and -DR53. (HLA-DR53 is directed against a protein encoded by the DRB4 gene, which is in a haplotype with the DRB1*07:01.) After plasma exchanges and before HSCT, there was a further rise in the HLA-DR53 antibody, likely due to granulocyte transfusions given for invasive fungal infection.

3 Supplementary Figure 1 Comparison of BM cellularity after haploHSCT with FCC conditioning used for matched sibling and unrelated donor HSCT for SAA. Percentage of BM cellularity at days +28 and +100 and at 1 year after HSCT are compared, as well as haploHSCT with FCC matched sibling and unrelated donor HSCT. Scatter plot shows values and median for percentage of BM cellularity, corrected for age by adding patient age to the recorded percentage of BM cellularity. Sib indicates sibling; Mud, matched unrelated donor. *Mann-Whitney test, **Kruskall-Wallis test.
