Clinical and economic impact of flow cytometry crossmatching in primary cadaveric kidney and simultaneous pancreas-kidney transplant recipients.

Abstract：

:We retrospectively compared the clinical and financial impact of a final cross-match by T cell flow cytometry (FXM) versus conventional complement-dependent cytotoxicity (CXM) in consecutive primary cadaveric kidney (K) and primary simultaneous cadaveric pancreas-kidney (SPK) transplant recipients. Mean follow-up was 14 months for both the K (range, 5-22 months) and SPK (range, 5-22 months) recipients. There were no instances of a positive CXM result if the FXM result was negative. However, 18 of the 102 (18%) K recipients and 11 of the 66 (17%) SPK recipients were FXM positive, CXM negative, but no grafts lost to hyperacute rejection in this group. In addition, patient survival, graft survival, incidence of acute rejection, and kidney and pancreas function (immediate and late) were not different in the FXM-positive versus the FXM-negative groups. Charges for the CXM and FXM methods were compared over a 6-month period. During that period, the FXM charges averaged $583 less per recipient than the CXM charges (58% reduction in charges), and the time required to perform the FXM method was 50% of that required for the CXM method. These results demonstrate that a clinical pathway for primary transplantation that utilizes the FXM rather than the CXM final cross-match is clinically safe, with no adverse effect on posttransplant outcome, reduces organ preservation time by shortening the waiting period for the final cross-match results, and significantly reduces the tissue typing charges. However, about 9% of all primary K and SPK recipients will be FXM positive, CXM negative on final cross-match and will be unnecessarily denied a transplant. In this study, we describe a method to identify these patients so that they can be tested by traditional CXM to avoid being denied access to donor organs.
