Kidney transplantation using elderly non-heart-beating donors: a single-center experience.

Although acceptable outcomes have been reported in both non-heart-beating (NHB) and elderly donors individually, the large pool of elderly NHB donors has not yet been fully utilized. In 1994, we expanded our transplant protocol to include NHB donors aged over 65 years and this study compares the clinical outcomes with regular NHB transplantations. Up to June 2005, 24 patients were transplanted at our center with kidneys from NHB donors aged 65 years or more, whereas 176 patients received grafts from conventional NHB donors during the same period.

Functional versus structural matching: can the CTLp test be replaced by HLA allele typing?

Human leukocyte antigen (HLA) incompatibilities are the most important immunological barriers to bone marrow transplant success when using unrelated donors. Until recently, standards for donor selection included serological methods for HLA class I antigens and DNA-based typing for HLA class II alleles. In our center cytotoxic T-lymphocyte precursor (CTLp) assays have been an integrated part of the search selection procedure as well.

Risk factors for cytomegalovirus infection and disease in renal transplant recipients: HLA-DR7 and triple therapy.

In a prospective study, an analysis of risk factors for the development of cytomegalovirus (CMV) infection and disease was performed on 77 renal allograft recipients. Twenty-five out of the 77 recipients (32%) had a CMV infection. Twenty-two of the recipients received triple immunosuppressive therapy (cyclosporin A, prednisolone, and azathioprine) while the remaining 55 received standard therapy (cyclosporin A and prednisolone).

The role of the spleen in pancreas transplantation.

Early graft thrombosis and rejection of the graft are the two major causes of graft failure in pancreas transplantation. Inclusion of the spleen in the pancreatic graft has been purported as a possible solution to both complications, but severe graft-versus-host disease led to abolishment of this procedure. By irradiating the donor spleen ex vivo during cold storage, we successfully prevented graft-versus-host disease, allowing us to evaluate the advantages of clinical pancreaticosplenic transplantation.
