BACKGROUND & OBJECTIVES: Antibodies specific to donor human leucocyte antigen
(HLA) play a critical role in graft rejection and graft loss. In recent years,
techniques for their detection have evolved significantly providing an
ever-increasing degree of sensitivity and specificity, from the conventional
cell-based assays to the advanced solid-phase system based on the Luminex
platform. Consensus is still evolving on the routine employment of all these
methods, either stand alone or in combination. The objective of this study was to
explore the near-accurate mean fluorescence intensity (MFI) cut-off values
detected on Luminex platform predicting the strength of cell-based crossmatch
results. METHODS: Serum samples from 116 primary renal transplant recipients
awaiting transplantation were tested for the presence of antidonor antibodies by
the complement-dependent cytotoxicity (CDC) and flow crossmatch (FCXM) methods
with their corresponding donors as well as for HLA-donor-specific antibodies
(DSA) detection using a sensitive single antigen bead (SAB) assay. RESULTS: None
of the patients having HLA Class I DSA with MFI values <1000 showed positivity
for T-cell FCXM or CDC crossmatch, while in the group having MFI values between
1000 and 3000, 54 per cent showed positivity for the FCXM but none by the CDC
method. However, in the group having MFI values >3000, 95 per cent of cases were
positive for FCXM. Further, those groups with MFI values between 3000 and 5000,
only 36 per cent were positive for CDC crossmatch, while 90 per cent showed
positivity in the group with MFI >7000. INTERPRETATION & CONCLUSIONS: A cut-off
MFI value of 3000 for Luminex SAB-based assay was found to significantly
correlate with the FCXM positivity while a MFI value of 7000 and above predicted
a positive CDC crossmatch. MFI cut-off value obtained as a surrogate marker for
CDC and FCXM tests will help in resolving the limitations of different cell-based
techniques.
