Rifampin is sometimes associated with hematologic complications such as hemolytic anemia or thrombocytopenia. Patients with drug-induced thrombocytopenia develop a
drug dependent antibody that binds to platelets in the presence of the drug causing platelet clearance. It has been previously proposed that the antibody binds the drug,
resulting in an immune complex that is then adsorbed onto platelets. However, it has been recently known that drug-dependent antibodies bind to one or more of the platelet
membrane glycoprotein Ib, lIb,IIIa, and IX.
We, hereby, report a case of rifampin-induced thrombocytopenia in which drug-dependent antibody specific for platelet glycoprotein Ib/IX and IIb/IIIa was
demonstrated by modified antigen capture ELISA method. The case was a 37 year-old female who had had pulmonary tuberculosis and taken antituberculous regimen including
rifampin. Intermittent epistaxis appeared 10 days after treatment with rifampin. She was admitted to hospital due to gingival bleeding for 3 days and menorrhagia for 2 days. On admission, her platelet count was dropped to 7,000/μL.
