The primary objective of this revised protocol will be to examine the safety and efficacy of IVIG 2gm/kg (maximum dose 140g) given on day#0 & day #30 plus Rituximab 1gm given on day #15. Transplanted patients will receive additional doses of Rituximab 1gm at 3 months post-transplant if donor specific antibody (DSA)levels remain or become positive or at 6M if de novo DSA occur. All transplanted patients who remain DSA negative, will not receive additional Rituximab. All transplanted patients will have a protocol biopsy at transplant and at 12 months. All subjects will have to complete 5 visits in a pre-transplant phase of the study. Patients who are transplanted will have additional 5 post-transplant visits. The following are research-related procedures:
