A single-institution experience of performing bloodless transplant in Jehovah's Witness patients.

OBJECTIVE/BACKGROUND: Autologous stem cell transplant has been shown to prolong survival in multiple myeloma (MM). A common complication of the pre-transplant conditioning chemotherapy is severe multi-lineage cytopenias, resulting in significant transfusion requirements. Jehovah's Witnesses are members of a religious group that do not accept the transfusion of blood products. Many large transplant centers refuse to perform transplantation in Jehovah's Witnesses due to the complexity of treating cytopenic patients without blood product transfusions. However, some transplant centers that specialize in "bloodless" medicine and surgery have successfully transplanted in Jehovah's Witnesses without transfusion support.

METHODS

In order to maximize successful outcomes in this population, potential transplant candidates are treated with a variety of agents to maximize baseline hemoglobin and platelet counts. In preparation for the first two "bloodless" transplants for MM at our institution, we conducted a retrospective study of patients with MM who underwent a transplant in the preceding year.

RESULTS

Of the 60 patients reviewed, only six required packed red blood cell transfusion, whereas 39 required at least one platelet transfusion. These findings helped us to design a novel protocol for a "bloodless" autologous transplant. We administered romiplostim, a thrombopoietin (TPO) agonist, along with aminocaproic acid, desmopressin, and vitamin K post-transplant to two Jehovah's Witness patients to mitigate the risk of thrombocytopenia. Neither patient experienced significant bleeding nor qualified for platelet transfusion, and underwent successful and uncomplicated transplantation.

CONCLUSION

We propose that the use of romiplostim or similar TPO agonists can be used to maximize the chance of a successful "bloodless" transplant for stem cell recipients.
