title: Diagnostic and prognostic value of antibody-dependent cellular cytotoxicity and lectin-induced cellular cytotoxicity tests for renal graft rejection.
abstract: Peripheral blood lymphocytes from both normal subjects and kidney allograft recipients, before and on the 4th to 5th days after transplantation, were examined for antibody-dependent cellular cytotoxicity (ADCC) and lectin-induced cellular cytotoxicity (LICC). The graft recipients were treated with standard immunosuppression, which included azathioprine and prednisolone. 51Cr-labeled L1210 cells were used as targets for these two tests. ADCC and LICC activity were evaluated in the presence of rabbit anti-L1210 anti-serum and phytohemagglutinin (PHA), respectively. Comparison of the results obtained from healthy subjects with those of patients before grafting showed a significantly higher LICC activity in the latter group. The ADCC activity did not differ between the groups of healthy females and those awaiting transplantation but it was significantly decreased in the group of males awaiting transplantation as compared to healthy males. Four to 5 days after transplantation, the activity of ADCC and LICC remained unchanged in spite of the immunosuppressive treatment in 37 and 61% of the patients studied, respectively. In most of the patients, high ADCC and/or LIcC activity was followed by an accelerated acute rejection episode. A correlation between the ADCC and LICC activities, measured 4 to 5 days after transplantation, and the time of the first rejection episode was found. We conclude that double screening with ADCC and LICC tests in the 1st week after transplantation is valuable.
