    Abstract

    Background: Churg-Strauss syndrome (CSS) is a rare, idiopathic systemic vasculitis. There is emerging evidence of an association between the presence or absence of antineutrophil cytoplasmic antibodies (ANCA) and clinical phenotype. Thromboembolism is an increasingly recognised complication of the disease. Aims: Given the paucity of Australian data, the aim of this study was to examine the clinical and laboratory features of CSS in a single Australian centre. Methods: We performed a retrospective review of all patients who fulfilled the American College of Rheumatology classification criteria for CSS managed at the Department of Immunology, Royal Adelaide Hospital between 2002 and 2008. Results: Nineteen patients were included. All patients had asthma and most had upper airway involvement. Peripheral nerve, musculoskeletal, gastrointestinal and cutaneous involvement was common. Renal and cardiac involvement was uncommon in this series. Histological confirmation was obtained in 15 patients (78.9%). Ten patients (52.6%) were ANCA+, and these were more likely to have musculoskeletal involvement, such as arthralgia or myalgia (odds ratio 57, P = 0.005). Thrombosis was a feature at diagnosis in six patients (31.6%); two of these recurred with relapse. Sixteen patients (84.2%) were followed up; five died, and mean survival was 8.9 years. Conclusions: This is the first Australian study to focus on CSS. Our results demonstrate similar presentation and prognosis of CSS to previous descriptions; however, we noted that musculoskeletal involvement was more common in ANCA+ patients. In our series, thrombosis was a significant complication and we suggest that thromboprophylaxis may be warranted.
