The organ donor was of blood group O D+C+c+E+e+ K+k+ Le(a+b‐) and the recipient, A<sub>1</sub> D‐C‐c+E‐e+ K‐k+ Le(a‐b‐).</p> <p>The donor and recipient were both tested for irregular antibodies.

On day 10, anti‐A antibodies were detected in the recipient's serum and eluted from his RBCs. At the same time, the patient developed multiple alloantibodies: anti‐D, anti‐C, anti‐E, anti‐K and anti‐Le<sup>a</sup> against the donor's erythrocyte antigens.</p> </sec> <sec id="vox12253-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Although serological analysis and haemolytic parameters confirmed the diagnosis of PLS which required transfusion support, no sign of graft damage due to recipient's immune reaction was detected. This case illustrates the required follow‐up of the recipient after transplantation.</p> </sec> </abstract>
