Answer

Corticosteroids are the cornerstone of treatment. Additional courses include the following:

  • Idiopathic PAN that is steroid refractory or includes major organ involvement: corticosteroids plus cyclophosphamide are the standard of care
  • Hepatitis B–related PAN: corticosteroids with antiviral agents (eg, vidarabine, interferon alpha-2b) and plasmapheresis
  • In patients with steroid-refractory and recurrent PAN, case reports describe response to treatment with biologic agents (eg, infliximab, etanercept, tocilizumab, tofacitinib, rituximab)
  • Severe PAN: plasma exchange has been used
