Is HLA matching required for kidney transplant?

HLA typing is a crucial step in renal transplantation, as recognition of foreign HLA by recipient T lymphocytes would trigger an immune response. T lymphocyte activation initiates a cascade of mediators that direct the immune system against the allograft[8].

What is HLA matching in kidney transplant?

Human leukocyte antigen (HLA) matching between potential donors and transplant candidates is determined by comparing their HLA antigens.

Can Pirche II matching outmatch traditional HLA matching?

Overall, we found that the PIRCHE-II score could not outmatch the traditional HLA mismatch.

Does HLA matching matter in the modern era of renal transplantation?

There is no effect of HLA matching in young donors (<35 years of age) for 5 year allograft survival. Donors less than <5 years have similar survival to older donors. Class I HLA MM does not affect kidney transplant outcome.

What is a 10 10 HLA match?

Matching for the HLA-A, -B,- C,- DRB1 and -DQB1 loci is referred to as a 10/10 match, when HLA-DPB1 is included it becomes a 12/12 match. Matching for HLA-A, -B, -C, and -DRB1 loci is an 8/8 match. There is still no international standard for reporting DRB3/4/5 as well as DQA1 and DPA1 mismatches.

Who is the best match for a kidney transplant?

Recipients with blood type AB… can receive a kidney from blood types A, B, AB and O (AB is the universal recipient: recipients with AB blood are compatible with any other blood type)

What is a good HLA match?

An HLA identical or fully HLA matched sibling is considered the optimal and first choice graft for allogeneic HCT. The recipient, siblings and parents (where available) should be HLAA, -B typed at intermediate or higher resolution and HLA-DRB1 typed at high resolution by DNA-based methods as a minimum requirement.

What is HLA matchmaker?

HLAMatchmaker is a structurally based algorithm that considers HLA alleles as strings of distinct molecular configurations that can be recognized by HLA antibodies important in transplantation.

Which HLA is most significant in transplantation?

HLA class I and II matching is important in organ transplantation [3] especially in kidney and bone marrow transplantation. In heart and lung transplantation, HLA match at the DR locus is important but there is some difficulties like ischemic times, availability of donors and clinical need of recipients.

Why is HLA matching important?

HLA matching is important for transplant HLA matching promotes the growth and development of new healthy blood cells (called engraftment) and reduces the risk of a post-transplant complication called graft-versus-host (GVHD) disease.

What is a 12 12 HLA match?

The 12/12 UHR HLA-matched pairs have significantly higher survival probabilities than patients who received either a 12/12 CDS match (ie, where there is the presence of only intronic or untranslated region mismatches) or any other HLA mismatch.

What is a perfect HLA match?

Siblings who have the same parents are most likely to be an identical HLA match. These siblings have a 1 in 4 chance of being a perfect HLA match. That means they have perfectly matching colored strings. There is also about a 1 in 2 chance that siblings will share half of the HLA markers and be a half-match.
