title: Thrombotic thrombocytopenic purpura in a case of brucellosis.
abstract: Thrombotic thrombocytopenic purpura (TTP) is characterized by disseminated thrombotic occlusions located in the microcirculation and a syndrome of microangiopathic hemolytic anemia, thrombocytopenia, fever, and renal and neurologic abnormalities. Thrombotic thrombocytopenic purpura is encountered in a variety of clinical situations such as viral, bacterial, and mycobacterial infections, autoimmune disorders, drug reactions, connective tissue disease, and solid tumors. In this report, we present TTP in a case of brucellosis because of rare presentation. A 7-year-old girl was admitted with the complaints of headache, fever, hematuria, malaise, jaundice, epistaxis, and purpura. Her physical examination revealed conjunctival pallor, scleral icterus, petechial-purpuric skin lesions on both legs, and confusion. Laboratory tests showed hematocrit 14%; hemoglobin 4.8 g/dL; platelet count 6000/mm(3), and reticulocytosis 6%. Peripheral blood smear revealed fragmented red blood cells and a complete absence of platelets. The clinical and laboratory findings were consistent with TTP. Serum antibrucella titration agglutination test was found to be 1/1280 positive.
