[Polyarteritis Nodosa, a vanishing vasculitis since its main cause has been identified].
The polyarteritis nodosa is a vasculitis for which the main cause had been identified as hepatitis B, a chronic infectious disease inducing an overshooting immune reaction. Thanks to this discovery, the treatment of polyarteritis nodosa has changed from a symptomatic immunosuppressive therapy to a treatment strategy focusing on the disease inducing infectious agent. Vaccination against hepatitis B- virus has been instrumental in the reduction of the prevalence of polyarteritis nodosa. In case of the rare entity of polyarteritis nodosa without hepatitis B, only a symptomatic immunosuppressive therapy can be prescribed. The history of polyarteritis nodosa clearly illustrates that future research in the field of so called autoimmune diseases should focus on the causes rather than on the immunologic effector mechanisms and/or the symptomatic immunosuppressive therapy.
