The relationship of infectious agents to inflammatory myositis.
Several infectious agents have been linked to chronic inflammatory myositis. The mechanisms proposed usually involve presumed persistent infection or induction of an autoimmune response following infection. Agents most often implicated are the enteroviruses (especially coxsackieviruses), echoviruses in patients with agammaglobulinemia, retroviruses including HIV-type 1 and human T-cell lymphotropic virus type 1, and the protozoan Toxoplasma gondii. In the majority of cases, however, no specific infectious agent can be identified.
