An analysis of children with brucellosis associated with isolated thrombocytopenia.

Hematologic abnormalities of mild anemia and leucopenia have been frequently associated with acute brucellosis, but thrombocytopenia are less frequently seen. In the present study, we documented 5 (2.6%) isolated thrombocytopenic patients with the manifestations of brucellosis observed during the course of active infection. Five (2.6%) patients, 4 boys and 1 girl, with ages ranging from 2 to 14 years, had isolated thrombocytopenic at diagnosis. In 5 (2.6%) patients, platelet counts ranged from 39,000 to 120,000/mm(3). Tube agglutination tests for brucellosis were positive for all patients (1/160-1/1280). All patients recovered completely, and their thrombocytopenia returned to normal by 2 to 4 weeks after antibiotic treatment of brucellosis. In our study, we present 5 patients with Brucella-induced thrombocytopenia mimicking idiopathic thrombocytopenic purpura to emphasize the isolated thrombocytopenia and the resolution of thrombocyte counts following treatment of brucellosis.
