Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients Cyclosporine → Lower Incidence of AIDS 31% versus 90% at 5 years Inhibition of HIV Replication Binding to HIV -1 Gag protein
Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients HAART – 1996 Highly active antiretroviral therapy HIV+ ≠ AIDS
Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients If HIV+ ≠ AIDS Why deny transplantation to HIV+ patients?

Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients Multicenter NIH Trial In Progress
Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients 1.In the pre-HAART era, transplantation was uncommon, although the results with kidney transplantation were reasonable. 2.HAART has changed the natural history of HIV, and has led to an increased interest in transplantation. 3.A number of single centers have achieved reasonable outcomes after kidney transplantation. 4.Acute rejection may be more common in HIV+ recipients than HIV- recipients.
Thomas E. Starzl Transplantation Institute Transplantation in HIV+ Recipients 5.The interaction between protease inhibitors and calcineurin inhibitors is important. 6.Preconditioning with Campath followed by tacrolimus monotherapy may be a reasonable approach to immunosuppressive management in HIV+ recipients. 7.The current NIH-sponsored trial should provide more information about outcomes in HIV+ patients undergoing transplantation.
