Published series on Churg-Strauss syndrome (CSS) come from tertiary referral centres. We retrospectively studied 23 patients with CSS (18 male) seen over 14 years (1982-1995) in a District General Hospital serving a population of 500 000. Mean age of onset of vasculitis was 57, 10-19 years older than in previous series. The commonest clinical features were asthma (22) and eosinophilia > 1.5 x 109/l (21). Systemic vasculitis involving two or more extrapulmonary organs occurred in 22 patients, with specific organ involvement of nervous system (18), joints (13), muscles (13), lungs (11), skin (11), kidneys (11), heart (10), and bowel (7). Various classification systems were applied including the Lanham criteria, which were met in 19 patients; the American College of Rheumatology criteria, met in 14; Churg and Strauss criteria, met in four; and the Chapel Hill Consensus definition, met only in two. ANCA was detected in 10/17 patients where measured. Treatment included corticosteroids (21), cyclophosphamide (8), azathioprine (9), immunoglobulin (2), and methotrexate (1). During follow-up six patients died, two due to myocardial vasculitis (mean age 52 years), three due to infection (mean age 80 years), and one cause unknown. Significant long-term disability was due to asthma in five and neuropathy in six.
