Core Tip

Core Tip: We described a case of severe thrombocytopenia likely induced by latamoxef, an infrequent adverse drug reaction in a young patient with tuberculosis and Crohn's disease. We followed the changes in platelet counts and the appearance of purpura during latamoxef treatment and after drug withdrawal and excluded other possible causes of thrombocytopenia. Our findings suggested that the patient's thrombocytopenia was caused by latamoxef. This is the first reported case of severe thrombocytopenia induced by latamoxef in a young Chinese patient to the best of our knowledge.
