The transplant community, including patients and carers, physicians, scientists and health-care workers, has long benefited from the altruistic donations provided by sibling or unrelated volunteer individuals. It is, therefore, to our shame that it has taken over 40 years for a careful consideration of the rights of the donor to be fully informed of the nature of the research being undertaken in the transplant centre, to appear in the transplant literature. King and colleagues have given great thought to this matter and have concluded that when the donor is required to do more than simply provide cells for a straightforward transplant procedure or to provide data and/or material that will be used in an identifiable manner, the research protocol should be approved in the country of origin of both donor and patient, the donor should be fully informed and should have the right to refuse to participate. This seems entirely reasonable and, as the authors argue, in keeping with the spirit of the Helsinki agreement. The practicalities, interpretation and implications of such a recommendation, however, are not so simple. The authors particularly cite the example of a donor being asked to provide more than the usual number of cells because, for instance, a technical procedure necessitates a larger than the usual collection. But this is commonplace. T-cell depletion by ex vivo positive or negative selection is well known to result in the loss of potential repopulating cells, non-myeloablative preparative regimens are based in part on the ability to infuse large numbers of CD34+ cells and both strategies undoubtedly increase the risks of both graft failure and disease relapse, increasing the chance of a request for the provision of a second harvest and/or lymphocyte donations. Nonmyeloablative transplants have become the standard of care for several transplant indications, including myelodysplasia, myelofibrosis and low-grade lymphoproliferative disorders, yet, the donor centre is highly unlikely to know the nature of the conditioning regimen. Would this be considered a research protocol with respect to the donor or simply an inconvenience? If the patient was participating in a research protocol of myeloablative vs non-myeloablative conditioning, will the donor also be involved? The risk of inconsistency seems considerable.We routinely collect data about the donor that are required for donor selection and we have long submitted these data to local, national and international registries where they are used for retrospective analyses with research intent. Furthermore, gradual improvements in donor selection have resulted from technical developments in HLA typing, and research into cytokine polymorphisms
