CHURG‐STRAUSS SYNDROME IN AN HCV SEROPOSITIVE PATIENT

SUMMARY Churg‐Strauss syndrome was considered rare until leukotriene modifiers were introduced into medical practice in 1996. Since then, an increasing number of reports considering a possible relationship between leukotriene receptor antagonists and the Churg‐Strauss syndrome have been published. Hepatitis C virus (HCV) is a blood‐borne infection and a major health problem with an increasing prevalence worldwide. Previously, numerous reports suggested a relationship between HCV and certain autoimmune disorders such as cryoglobulinaemia and polyarteritis nodosa. We present a patient with HCV seropositive Churg‐Strauss syndrome and a history of systemic corticosteroid and leukotriene receptor antagonist use, and discuss the possible risk factors in the aetiology of Churg‐Strauss syndrome.
