HLA antibodies (HLA ab) in transplant candidates have been associated with poor outcome.
However, clinical relevance of noncytotoxic antibodies after heart transplant (HT) is controversial.
By using a Luminex-based HLA screening, we retested pretransplant sera from HT recipients testing negative for cytotoxic HLA ab and for prospective crossmatch.
Out of the 173 consecutive patients assayed (52±13y; 16% females; 47% ischemic etiology), 32 (18%) showed pretransplant HLA ab, and 12 (7%) tested positive against both class I and class II HLA.
Recipients with any HLA ab had poorer survival than those without (65±9 versus 82±3%; P=0.02), accounting for a doubled independent mortality risk (P=0.04).
In addition, HLA-ab detection was associated with increased prevalence of early graft failure (35 versus 15%; P=0.05) and late cellular rejection (29 versus 11%; P=0.03).
Of the subgroup of 37 patients suspected for antibody mediated rejection (AMR), the 9 with pretransplant HLA ab were more likely to display pathological AMR grade 2 (P=0.04).
By an inexpensive, luminex-based, HLA-screening assay, we were able to detect non-cytotoxic HLA ab predicting fatal and nonfatal adverse outcomes after heart transplant.
Allocation strategies and desensitization protocols need to be developed and prospectively tested in these patients.
