title: Alterations of blood group antigens in angio-immunoblastic lymphadenopathy with dysproteinemia.
abstract: Antigen analysis of the red cell membrane in a patient with angio-immunoblastic lymphadenopathy with dysproteinemia (AILD) with red cell autoantibody revealed that four blood group antigens had been acquired. These four antigens consisted of S of MNSs blood group, Lua of Lutheran blood group, and K and Kpa of Kell-Cellano blood group. These antigens disappeared and the Coombs' test became negative after complete remission induced by combination chemotherapy. Free amino acid analysis after Dispase treatment of red cell membrane suggested that the antigenic modifications were associated with abnormal composition of amino acids.
