Long-Term Followup of a Multicenter Cohort of 101 Patients With Eosinophilic Granulomatosis With Polyangiitis (Churg-Strauss).

Abstract：

OBJECTIVE:To assess the long-term outcome in eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA). METHODS:A total of 101 patients fulfilling the American College of Rheumatology criteria for EGPA were included between 1990 and 2011. Clinical features, antineutrophil cytoplasm autoantibodies (ANCAs), and Five-Factors Score (FFS) were assessed at diagnosis. Overall and cumulative survival rates, relapse-free survival, and sequelae were studied based on ANCA status and FFS. RESULTS:The rate of cardiomyopathy did not differ according to ANCA status. A total of 79.6% of patients achieved first remission, but 81.1% relapsed. ANCA-positive patients did not relapse more frequently but exhibited more severe disease with mononeuritis (P = 0.0004) and renal involvement (P = 0.02). Being Italian was the only prognostic factor associated with a higher relapse-free survival (P = 0.01), thanks to a longer maintenance of immunosuppressive drugs, suggesting the need for prolonged low-dose corticosteroids. Overall, survival reached 93.1% after a median followup of 6 years. No factor was associated with mortality, but patients over age 65 years with cardiomyopathy or ANCA positivity had more serious outcomes. Sequelae affected 83.2% of patients. Ear, nose, and throat (ENT) involvement was a protective factor for renal (P = 0.04) and cardiac (P = 0.03) morbidity. ANCA positivity was correlated with chronic kidney disease (P = 0.03) and chronic neurologic disability (P = 0.02). CONCLUSION:The actual challenges of EGPA management concern morbidity prevention and quality of life improvement. Long-term corticosteroid treatment appears to reduce relapse risk. ENT involvement is associated with less renal and cardiac morbidity. ANCA positivity predicts renal and neurologic damage.
