Flow cytometric crossmatching and outcome one year after renal transplantation

Previous studies have shown that flow cytometric crossmatch assays can identify an at risk population in renal transplantation. We used the assay for recipient selection for 1 year. Recipients with donor T cell directed IgG were excluded from transplantation and those with B cell directed IgG were treated with increased immunosuppression. The transplants performed over this period (n = 126) were compared with an earlier series (n = 118) in which flow cytometric crossmatch results did not influence patient management. The results were evaluated for mortality and graft outcome at 3 months and 1 year. In addition, postoperative complications and duration of hospital stay were also assessed.
