[Joint manifestations of Yersinia enterocolitica infections]

Different recent studies, notably Scandinavian studies, have described a "rheumatism" caused by Yersinia enterocolitica infection. The picture usually seen is that of a subacute, febrile oligoarthritis predominantly in the lower limbs, associated with diarrhoea and hyperleucocytosis, polynucleosis, and a marked increase in the sedimentation rate. Benign carditis may also be associated. The diagnosis rests on the discovery of the organism by coproculture and on serodiagnosis. Evolution is favourable within several weeks or several months. Treatment includes antibiotics and antinflammatory preparations.
