Recipient Selection and Immunological Considerations

Organ Allocation Systems

• Master the principles of organ allocation, including fairness, utility, medical urgency, and equity.
• Understand the specific allocation algorithms and scoring systems for various organs, such as the MELD (Model for End-Stage Liver Disease) score for liver transplantation and CPRA (Calculated Panel Reactive Antibody) for kidney transplantation.

Pre-Transplant Immunological Assessment

• Perform and interpret results from HLA typing and crossmatching tests, including flow cytometry crossmatch.
• Understand the significance of Panel Reactive Antibody (PRA) and C1q assays in assessing recipient sensitization.
• Utilize virtual crossmatching techniques to predict donor-recipient compatibility.

Immunosuppressive Regimens

• Gain expert knowledge of induction immunosuppressive therapies (e.g., basiliximab, alemtuzumab, anti-thymocyte globulin).
• Understand the components of maintenance immunosuppressive regimens, including calcineurin inhibitors (e.g., tacrolimus, cyclosporine), antiproliferative agents (e.g., mycophenolate mofetil, azathioprine), and corticosteroids.
• Explain the mechanism of action, common side effects, and strategies for therapeutic drug monitoring for each class of immunosuppressant.

Tolerance and Desensitization Strategies

• Explore advanced approaches to induce immune tolerance in transplant recipients.
• Understand strategies for desensitization to reduce pre-existing alloantibody levels in highly sensitized recipients, including plasmapheresis and intravenous immunoglobulin (IVIG).
