[Familial autoimmune hemolytic animia (AIHA) with negative Coombs test, lymphocytopenia and hypogammaglobulinemia]
A family with several cases of autoimmune hemolytic anemia and dysgammaglobulinemia is described. Two sibling had documented antierythrocyte antibodies, but a third had repeatedly negative Coombs tests. Diminished immunoglobulin-producing cells and a hypogammaglobulinemia were found, but no functional defect of humoral or cell-mediated immunity could be detected.
