Removing a failed kidney allograft improves survival?

In a fascinating article from November's Journal of the American Society of Nephrology, researchers present data suggesting that patients returning to dialysis after a transplant fails experience improved survival if the kidney is removed. In this study, despite correction for comorbidities and socioeconomic factors, graft nephrectomy prolonged survival. One explanation of the results might be that nephrectomy removes an inflammatory stimulant and would allow complete withdrawal of immunosuppression and its risks. This finding is somewhat contradictory to current dogma which suggests that immunosuppression should be continued once returning to dialysis in order to preserve residual renal function. This study's finding would need to be reproduced with a prospective randomized trial to reduce bias but in the meantime, is quite compelling.

Major breakthrough in transplantation immunity

Professor Jonathan Sprent and Dr Kylie Webster from Sydney's Garvan Institute of Medical Research, in collaboration with colleagues, Dr Shane Grey and Stacey Walters reported a major breakthrough in the area of transplantation tolerance in this month's issue of the Journal of Experimental Medicine. This fascinating report describes a method of inducing tolerance of islet cell grafts transplanted into mice. The technique involves combining an antibody with IL2 in a complex that upregulated T-regulatory cells, suppressing T-Killer cells that lead to acute rejection. No immunosuppression was required by the animals and 80% enjoyed tolerance of the graft. While these results are preliminary and in an animal model, it does offer a glimpse at a potential strategy that might obviate  or significantly reduce the need for toxic medications in human transplant recipients of all kinds.
