Major Histocompatibility Complex Part II: Clinical significance of anti-HLA antibodies in transplantation

Author: Kelley M.K. Hitchman, MS, PhD, F(ACHI)

Learning Objectives:

  1. Review the history and evolution of diagnostic criteria for antibody mediated rejection (AMR).
  2. Describe mechanisms in which mismatched donor HLA antigens can cause and contribute to AMR.
  3. Explain the components and process of performing a virtual crossmatch, as well as how it is applied as a specialized immunologic risk assessment for transplant pairs.
  4. Summarize different timings and manifestations of AMR.
  5. Understand how HLA-DSA detection can correlate with rejection and how anti-HLA antibody testing can help inform desensitization.
