Summary
A kidney transplant recipient with blood group AB experienced hemolysis due to anti-A antibodies from the donor
Area of Science:
- Nephrology
- Transplantation Immunology
- Hematology
Background:
- Organ transplantation requires careful ABO blood group matching to prevent immune rejection.
- Cadaveric kidney transplants involve potential risks beyond simple blood type compatibility.
Observation:
- A 35-year-old patient with blood group AB developed hemolysis one week post-kidney transplant from a blood group B donor.
- The patient's serum contained anti-A antibodies, originating from donor passenger lymphocytes.
Findings:
- The alloimmune hemolysis resolved spontaneously without intervention.
- This case highlights ABO-compatible but non-identical transplantation risks.
Implications:
- Clinicians must maintain vigilance for post-transplant hemolysis in non-identical ABO transplants.
- Differentiating this immune complication from other causes of hemolysis is crucial for patient management.
