More hospitals have begun offering so-called desensitization therapy to help high-risk patients who have a willing but non-matching living donor receive an organ their bodies otherwise would reject. Some specialty centers have reported success but it wasn't clear how well the approach would work when used widely. "Desensitization is still not for every transplant center," said senior author Dr. Dorry Segev of Johns Hopkins University, which helped pioneer incompatible transplants.
