[Immunoallergic hemolytic anemia, thrombopenia and acute renal failure induced by aspirin].

The first case of haemolytic anaemia with thrombocytopenia and acute renal failure induced by ingestion of aspirin in a 22-year old woman is reported. An IgM anti-aspirin antibody which agglutinated erythrocytes of the patient and of ABO compatible donors in the presence of aspirin was isolated in the serum. In addition, the allergic nature of the patient's hypersensitivity to aspirin was confirmed by positive lymphocyte transformation and basophil degranulation tests in the presence of the drug.
