Summary
Liver transplant recipients often develop red blood cell (RBC) antibodies, posing transfusion risks. Careful monitoring and management are crucial for patient safety during liver transplantation.
Area of Science:
- Transfusion Medicine
- Immunology
- Hepatology
Background:
- Liver transplant recipients require substantial blood transfusions.
- Red cell (RBC) alloimmunization is a significant concern in these patients.
Purpose of the Study:
- To investigate the frequency and characteristics of RBC antibody issues in liver transplant recipients.
- To assess the clinical significance and management of RBC antibodies in adult and pediatric liver transplant patients.
Main Methods:
- Retrospective review of medical records for 496 adults and 286 children undergoing 1000 liver transplants.
- Analysis of RBC alloantibody prevalence before and after transplantation.
- Evaluation of direct antiglobulin tests and anti-recipient ABO antibodies.
Main Results:
- RBC alloantibodies were present in 22% of adults and 14% of children.
- Clinically significant antibodies appeared post-transplant in 7.5% of adults and 5.2% of children.
- ABO-unmatched grafts led to anti-recipient ABO antibodies in 37% of cases, with 13 experiencing hemolysis.
Conclusions:
- A significant proportion of liver transplant patients experience diverse RBC antibody problems.
- Proactive laboratory support, including antibody screening and management, is essential for successful liver transplantation programs.
