| Introduction |
|---|
Inflammation and necrosis of blood vessel walls occurs in a dozen or so primary vasculitic disorders. An attempt to classify these diverse forms of vasculitis resulted in the Chapel Hill international consensus definitions, which used vessel size as the determinant of classification [1]. Wegener's granulomatosis, microscopic polyangiitis and ChurgStrauss syndrome are described as small vessel vasculitides and are commonly associated with anti-neutrophil cytoplasmic antibodies (ANCA).
The incidence of ANCA-associated vasculitis is 20 per million population occurring more often in an elderly population (peak age 55 to 70 yr) [2]. Prevalence rates are far higher since the introduction of successful immunosuppressant treatment regimes. Of the three entities, ChurgStrauss syndrome is the least common (13 per million population). Some studies of ANCA-associated vasculitis have suggested that pulmonary involvement is associated with a poor outcome [3, 4].
