The study by Loupy et. al. shows an important role for complement-fixing (C1Q+) donor-specific HLA antibodies (DSA) in risk prediction of kidney allograft loss. The study examined 1016 kidney transplant recipients transplanted across negative T- and B-cell cytotoxic crossmatches with subsequent testing by Luminex single antigen beads for the detection of complement-fixing as well as […]

The ability to detect anti-HLA antibodies is very sensitive and specific, but it is not clear if all antibodies are the same. Specifically, some antibodies may bind and activate complement better than others. In this retrospective study, the presence of antibodies that could fix C1q and initiate the complement cascade was associated with higher rates […]

The recent development of Luminex reagents capable of detecting complement fixing HLA antibodies has sparked a lot of interest in the best way to apply this information. This study examined C1Q-fixing HLA antibodies in a retrospective study of pre-transplant samples in patients transplanted across a negative cytotoxic cross-match. Of the 837 sera examined, 210 contained […]
