HLA mismatch

HLA mismatch

The nonmatching of HLA antigen in recipients of renal and other allografts. See Transplantation. Cf HLA match.

HLA mismatch

, human leukocyte antigen mismatch
The number of human leukocyte antigens (HLAs) found on the cells of a donor organ but not found on the cells of the organ recipient. The greater the disparity between the antigens, the lower the probability of a successful transplantation.

The degree of HLA mismatch (spanning 0/6 to 6/6) between the donor and the recipient did not affect either the safety or the efficacy of the therapy.
Thus, minimizing HLA mismatch between a donor and a recipient is required to ensure successful transplantation [54-56].
These findings were borne out with multivariate analysis for both donors and recipients (e.g., HLA mismatch, donors who were hypertensive, recipients with diabetes).
Humoral/AMR rejection cases (C4d deposition in the peritubular capillaries) and the cellular rejection biopsies as per the BANFF 2003 criteria were correlated with their HLA mismatch scoring, pre-transplant PRA levels.
Total nucleated cell dose thresholds depend on the degree of HLA disparity, with a greater TNC dose required for each additional HLA mismatch [17,18].
In addition, one-way multivariate analysis of variance (MANOVA) to test the hypotheses that there would be one or more mean difference between the factors (HLA antibody, MICA antibody and HLA mismatch) and graft survival was performed to check for the effect of potential confounders.

In our center, the decision of desensitization was mainly based on the laboratory testing results for pretransplant PRA, preformed DSA, HLA mismatch (MM), and flow complement-dependent cytotoxicity (CDC).
With the "NetMHCIIpan 3.1" Internet-based predication tool, the amino acid sequence of each HLA mismatch (extracellular domains only, in the FASTA format found on http://www.hla.alleles.org [41]) was used to predict the binding affinity of all allo-HLApep sequences to the recipients' HLA class II antigens' peptide groove.
Although the number of HLA mismatches is a potent predictor of transplant outcome, not every HLA mismatch will have an equal effect on graft failure [6, 7].
