Overview of polyarteritis nodosa

Polyarteritis nodosa is a rare systemic vasculitis that affects small to medium arteries. It typically occurs in middle-aged or older adults and males are more commonly affected. It is commonly associated with active viral hepatitis B and C infections.

If polyarteritis nodosa is suspected, discuss urgently with a specialist to determine if immediate intensive induction therapy is required. Rheumatologists strongly encourage direct contact by general practitioners to expedite referral or obtain advice on treatment (eg before starting high-dose systemic corticosteroids). A delay in treatment can result in serious organ-related complications.
