Following a literature review, we describe a fourth case of transfusion-rel
ated lung injury (TRALI) due to a leukocyte antibody with anti-HNA-3a (-5b)
specificity. The patient, a 72-year-old male, was admitted to hospital for
surgery following an abdominal aortic aneurysm. Postoperatively, after tra
nsfusion of 2 units of packed red blood cells (PRBC) and 2 units of fresh f
rozen plasma (FFP) concentrate, the patient developed typical signs of TRAL
I. Anti-HNA-3a was found in the serum of 1 of the 2 FFP units. The female d
onor had no transfusion history, but had had 2 pregnancies more than 35 yea
rs previously.
