I t was demonstrated in the preceding paper (1) that incubation of primary isolates of normal human amnion cells with specific rabbit antibody and normal human serum resulted in immune cellular injury as measured by two independent criteria of cytotoxicity. I t was further shown that the factors in normal human serum which were required in addition to specific antibody for production of cytotox...

Hemolysis is an uncommon and usually late complication of malignancy, and very rarely the presenting feature. Cancer-associated hemolysis may be immune-mediated, or may result from thrombotic microangiopathy accompanied by thrombocytopenia. We describe an unusual case of isolated hemolysis in the setting of occult metastatic breast cancer. The patient initially presented with symptomatic anemia...

BACKGROUND Immune-mediated hemolytic anemia (IMHA) is the most common hematologic immune-mediated disease in dogs. Complement fixation on erythrocytes causes hemolysis. Complement inhibition decreases hemolysis in people with the hemolytic disease and also may prove effective in treating IMHA in dogs. HYPOTHESIS/OBJECTIVES Evaluate the in vitro efficacy of 2 complement inhibitors used in huma...

The clinical hallmark of paroxysmal nocturnal hemoglobinuria (PNH) is chronic intravascular hemolysis that is a consequence of unregulated activation of the alternative pathway of complement (APC). Intravascular hemolysis can be inhibited in patients by treatment with eculizumab, a monoclonal antibody that binds complement C5 thereby preventing formation of the cytolytic membrane attack complex...

The mechanisms of sensitization and attachment of drugdependent antibodies to RBC in drug-induced immune hemolytic anemias are largely speculative. Nomifensine has been incriminated in causing immune hemolysis in a large number of patients. The hemolysis was usually of the so-called immune complex type, less commonly of the autoimmune type, and more surprisingly. few patients had developed both...
