Abstract
Introduction: Brucellosis is a major zoonosis affecting livestock and transmitted to humans; it is widespread worldwide with 500,000 new cases per year according to the World Health Organization. It has become rare in countries that have established an eradication policy of the disease in animals and pasteurization of milk, but remains endemo-epidemic in Algeria, where it constitutes a public health problem (incidence of 24.41 per 100,000 inhabitants in 2017). The disease is more crippling than fatal. Severe forms are exceptional, and deaths are rare, most often following endocarditis or complicated neurological damage. The biological diagnosis is made by culturing the samples (mainly blood cultures), serology or molecular biology methods. We report the case of a patient with complicated and fatal subacute multiorgan brucellosis. Observation: A 51-year-old man is hospitalized in cardiology for endocarditis, complicated by neurovascular and skin manifestations, discovered in the stage of severe renal failure, one of the dreaded autoimmune complications of infectious endocarditis. The diagnoses were confirmed by various radiographic (echocardiography, brain computed tomography, magnetic resonance imaging) and biological examinations. The brucellian etiology was proved by bacteriological test of blood cultures (Brucella melitensis) and Wright's serodiagnosis, in the absence of the Polymerase Chain Reaction (PCR) test.Entities:
