title: Microangiopathic Anemia of Acute Brucellosis - is it a True TTP?
abstract: Thrombotic thrombocytopenic purpura (TTP) is a severe disease, potentially fatal, if not diagnosed and treated promptly. TTP is clinically characterized by the pentad of thrombocytopenia, Coombs-negative hemolytic anemia, fever, renal abnormalities and neurological disturbances. Advances in recent years have delineated the molecular mechanisms of acquired and hereditary TTP.Many infectious organisms have been reported to be associated with TTP, especially mycoplasma, but few cases of Brucella infection associated with thrombotic microangiopathy have been reported.We describe a young woman who presented with TTP after acute infection with both Brucella melitensis and Brucella abortus. The patient completely recovered following aggressive therapy with plasmapharesis, high-dose corticosteroids and appropriate antimicrobial therapy.Since measurement of ADAMTS13 activity and neutralizing antibodies is now available, and none of the reported cases of brucellosis with thrombotic microangiopathy (including the present report) were tested, for better understanding of this rare association, we recommend this work-up in future cases.
