Transplantation in HIV+ Recipients Multicenter NIH Trial In Progress Thomas E. Starzl Transplantation Institute
Transplantation in HIV+ Recipients • In the pre-HAART era, transplantation was uncommon, although the results with kidney transplantation were reasonable. • HAART has changed the natural history of HIV, and has led to an increased interest in transplantation. • A number of single centers have achieved reasonable outcomes after kidney transplantation. • Acute rejection may be more common in HIV+ recipients than HIV- recipients. Thomas E. Starzl Transplantation Institute
Transplantation in HIV+ Recipients • The interaction between protease inhibitors and calcineurin inhibitors is important. • Preconditioning with Campath followed by tacrolimus monotherapy may be a reasonable approach to immunosuppressive management in HIV+ recipients. • The current NIH-sponsored trial should provide more information about outcomes in HIV+ patients undergoing transplantation.
