[Enterovirus infections and systemic clinical manifestations with prolonged inflammatory syndrome: association with a persistence of specific IGM antibodies]

We report 9 cases of enteroviral infection associated with systemic inflammatory disease (including 4 cases of vasculitis, 1 case of periarteritis nodosa, 1 case of Sharp's syndrome). We then reviewed 36 cases of enteroviral infection with persistent IgM antibodies diagnosed in the virology laboratory in a 6-year period: among them 11 cases were found to present with subacute or chronic inflammatory disease. We conclude that enteroviruses might be important triggers of systemic inflammatory disease.
