Abstract

A 27-year-old female was admitted to a hospital because of severe anemia (hemoglobin 4.9 g/dl) after taking PL (a drug for common cold consisted of Salicylamide, Acetaminophen, Caffeine and Promethazine methylene di-salicylate) and Cefadroxil (an oral antibiotic) for ten days. History and laboratory data leaded to a diagnosis of drug induced hemolytic anemia. 6 units of concentrated red blood cells were transfused and the suspected drugs were discontinued immediately. Though resolution of anemia and no further hemolysis were observed, progressive leukocytopenia developed since four days after the admission. Bone marrow aspiration revealed marked decrease of granulocytic series. The patient was transferred to our hospital and was isolated under laminar air-flow to prevent her from bacterial and fungal infections. She was treated with prednisolone and granulocyte-colony stimulating factor. She recovered from leukocytopenia in two weeks without suffering from any life-threatening infection. We extensively analyzed the suspected drugs and mechanism of hemolysis and granulocytopenia. Cefadroxil is turned out to be contributed to hemolysis by an immune complex mechanism. Cefadroxil and Salicylamide were suggested to be involved in gr...Continue Reading
