[Spondylodiscitis disclosing bacterial endocarditis. Apropos of a case. Review of the literature].

The authors report a case of infectious spondylodiscitis revealing a staphylococcal endocarditis in a patient with a Carpentier aortic heterograft. This case, along with 60 descriptions from the literature, has enabled them to specify the characteristics of occurrence of endocarditis during a spondylodiscitis. The clinical factors in favor of this association are: a pre-existing cardiopathy, an oral port of entry, occurrence of other rheumatoid manifestations, even more the presence of complications of endocarditis. The laboratory factors in favor of an association are: discovery of an inflammatory anemia, of circulating immune complexes, of a cryoglobulinemia, of a rheumatoid factor, of hematuria. But it is mostly the demonstration of streptococcus in blood cultures and other samples that should be an indication to search for an endocarditis, the course of which dominates the prognosis.
