<qa>  What is the name of the immunoglobulin intravenous?Dr. Lloyd Ratner, currently at Columbia University and former Chief of Transplant at Thomas Jefferson University Hospital and his former colleagues at Johns Hopkins University have studied the use of plasmapheresis in combination with Cytomegalovirus Immune Globulin Intravenous CytoGam to reverse a positive cross match and to transplant organs against ABO incompatible blood groups. This has enabled over 20 kidney transplants to be performed with patient and graft survival at one year being very similar to our traditional cross match negative and ABO compatible patients. These results are generally considered outstanding given the fact that antibody mediated rejection historically had a 75 to 100 incidence of graft loss.
