Polyarteritis nodosa related with influenza vaccine = Poliarteritis nodosa relacionada con vacuna contra la influenza

Vasculitis can be secondary to various processes, among them infections, malignancies, connective tissue diseases or medications, or primary, generally idiopathic. The reported adverse events after vaccination can be mild and transient or more serious such as autoimmune diseases. Possibly the most frequently described autoimmune phenomena after influenza vaccination are different forms of vasculitis. We report the case of a patient who presented a clinical picture of vasculitis classified as polyarteritis nodosa that began two weeks after receiving the influenza vaccine. After critically reviewing the literature, this would be the first clearly documented case of polyarteritis nodosa associated with vaccination against influenza.
