Symptoms and Signs
Patients usually present with systemic symptoms with single or multiorgan dysfunction. Common (and nonspecific) complaints include fatigue, weakness, fever, arthralgias, abdominal pain, hypertension, renal insufficiency, and neurologic dysfunction. The following symptoms should raise a strong suspicion of a vasculitis:
- Mononeuritis multiplex. Also known as asymmetric polyneuropathy is highly suggestive of vasculitis, since diabetes is the only other cause of this.
- Palpable purpura. If patients have this in isolation, it is most likely due to cutaneous leukocytoclastic vasculitis. If the purpura is in combination with systemic organ involvement, it is most likely to be Henoch-Schonlein purpura or microscopic polyarteritis.
- Pulmonary-renal syndrome. Patients with hemoptysis and renal involvement are likely to have Wegener's granulomatosis, microscopic polyangiitis, or anti-GBM disease (Goodpasture's syndrome).

“What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the

taffeta, I see no reason why thou shouldst be so superfluous
to demand the time of the day.”
