ABSTRACT
We found a case of Ael for the first time in Korea. The patient was 28-year-old woman admitted for the delivery of her first baby. Patient's red cells were typed as O, while the serum typing was A. The red cells were agglutinated by anti-H, but not agglutinated by anti-A1 or anti-AB. Adsorption of anti-A by patient's RBC was confirmed on the adsorption-elution test. In the saliva, only H substance was demonstable. A substance was not demonstrated either in the serum or in the saliva. A transferase was not demonstrated in patient's serum. One of the patient's sister and her daughter, and the patient's son also had same Ael phenotype.

Removal of leukocytes from blood components may prevent alloimmunization to leukocyte antigens, febrile nonhemolytic transfusion reactions, transmission of leukotropic viruses or bacteria, and graft-versus-host disease. New surface-modified fibrous polyester filters were evaluated; they require no special processing of blood components and can be used at the patient's bed-side. Pall RC100TM(Pall Co., USA) was used to filter 2 units of RBCs at a time for a total of 8 filtrations: mean red cell recovery rate was 88.7%, mean WBC removal rate 99. 99%, and mean residual WBC count after filtration 2.77x 10 5. Twelve units of apheresis platelets were filtered with Pall PL50TM(Pall Co., USA): mean platelet recovery rate was 90.7%, mean WBC removal rate 99.95%, and mean residual WBC count after filtration 6.99 x 10 5. This study indicates that these filters efficiently remove WBCs without significant loss of red cells or platelets and that this kind of filters can be easily used at the patient's bed side.
