title: Posttransplant serum analysis in human kidney allografts.
abstract: Monitoring of 25 first cadaver transplant recipients was carried out weekly after transplantation. A total of 441 sera were tested from these patients against B and T lymphocytes at 4 degrees C and 37 degrees C for development of cytotoxic antibodies. Thirteen of the 25 patients (52%) developed B-cold antibodies as their first antibodies and all had functioning kidneys. Five of the patients developed B-warm antibodies initially, and all 5 rejected their transplants within 24 days. Of the seven patients who did not develop antibodies, 3 rejected their kidneys within 72 days. We conclude that it is important to distinguish between two types of antibodies to B lymphocytes--those reactive in the cold and those reactive in the warm--since they have opposite effects. Of the 17 successful grafts, 13 first developed B-cold cytotoxins.
