TABLE II.

Comparison of HLA Antibodies in Patients With RBC Autoantibodies and/or Alloantibodies

RBC antibodies HLA antibody positive HLA antibody negative P-value
Alloantibodies only 7 (46.7) 8 (53.3) 0.021
Autoantibodies only 5 (55.6) 4 (44.4)
Allo- and autoantibodies 4 (66.7) 2 (33.3)
No RBC antibodies 9 (20.9) 34 (79.1)

The number of patients with HLA antibodies (n = 25) and without HLA antibodies (n = 48) is shown, stratified by RBC antibody history. The P-value is calculated by Fisher’s exact test.
