Ceftizoxime‐induced hemolysis due to immune complexes: case report and determination of the epitope responsible for immune complex‐mediated hemolysis

Abstract

The patient's antibody recognized a common structure in 10 oxime-type cephalosporins, and immune complexes formed by the antibody specifically or nonspecifically bound to red cell membranes. Therefore, when intermittent antibiotic therapy is required, as in this case, care should be taken in antibiotic selection to avoid drug-induced hemolytic anemia. In addition, when this type of hemolysis is observed, tests for antibody that reacts by adsorption and immune-complex mechanisms should be performed against penicillins and cephems to select antibiotics not showing a cross-reaction.
