Wheat germ agglutinin (WGA) has been shown to react specifically with solubilized I blood group substance, purified from papain treated human erythrocyte membranes. WGA and I react to form an affinity precipitate in immunodiffusion gels, a reaction which can be blocked by the incorporation of N-acetyl glucosamine into the gel. The I material was a strong inhibitor of both anti-I cold hemagglutination and WGA hemagglutination reactions. Utilizing the techniques of crossed immunoelectrophoresis we have clearly established that WGA and anti-I IgM cold antibody are reacting with the same membrane macromolecule (I antigen). WGA was then used in a rocket affinoelectrophoretic assay system to quantitate I substance. The limits of detection in this system was 25 ng.

This report described the second case in the literature of Waldenstrom's macroglobulinemia with combined cold- and warm- antibody autoimmune hemolytic anemia (CCW-AIHA). Both IgG and IgM red cell auto-antibodies (auto-Abs) were present in the patient's serum. The IgM auto-Abs had a high thermal amplitude and anti-I blood group specificity. The IgG auto-Abs did not reveal blood group specificity. This patient depended on steroids to control hemolysis, but responded well to chemotherapy and plasmapheresis. CCW-AIHA has rarely been reported. In this study, the literature is reviewed and the characteristic serological and clinical features of this rare category of autoimmune hemolytic anemia (AIHA) are discussed.

A 56-year-old woman developed mixed warm and cold antibody type autoimmune hemolytic anemia (mixed AIHA) associated with systemic lupus erythematosus. The patient was admitted to our hospital for acrocyanosis and shortness of breath. High fever and jaundice were observed. Urinalysis revealed protein and hemoglobin, and the sediment contained granular and hyaline casts. Her erythrocytes agglutinated markedly at room temperature. Her hemoglobin was 5.6 g/dl and reticulocyts were 19.3%. Total bilirubin, GOT and LDH were elevated, while haptoglobin and complements were abnormally reduced. Polyclonal increase of immunoglobulin, ANA and anti-Sm antibody were detected. The direct antiglobulin test was positive; IgG1, IgG3 and C3d were detected on the red cell surface. The cold agglutinin (CA) titer was 4096, showing anti-I blood group specificity, and was still active at 30 degrees C. Upon administration of prednisolone gradual increase of hemoglobin and decrease of reticulocytes were observed, indicating the healing of hemolysis. CA disappeared but the direct antiglobulin test remained positive. Mixed AIHA has been defined as the presence of both warm and cold antibodies. In addition, the presence of symptoms of cold agglutinin disease, or low-titer and high thermal amplitude CA might be necessary for the diagnosis of mixed AIHA.
