 The purpose of this study is to test the clinical and laboratory observations of IVIG therapy in the highly sensitized patient. We will study the effects of patients treated with IVIG or Cytogam in combination with plasmaphoresis to modulate the immune response in highly sensitized patients. The goal is to convert a positive crossmatch to a compatible crossmatch that would allow living related transplant to take place or to shorten time on the transplant waiting list.
