[Clinical features of allergic granulomatosis and angiitis (Churg-Strauss syndrome). Association with asthma symptoms].

We reported clinical and laboratory findings of 5 patients with Churg-Strauss syndrome (CSS), especially association with asthma symptoms. Subjects included 3 males and 2 females with a mean age of 53.8 year-old. In all 5 patients symptoms of neuropathy; mononeuritis multiplex and in some patients, other vasculitic symptoms; fever, diarrhea, abdominal pain and skin eruptions, were noted. These clinical features and laboratory findings; marked peripheral eosinophilia and elevation of serum ECP were normalized after steroid therapy. We investigated the relation between the occurrence of CSS and the symptoms of asthma. The mean duration of asthma in this series was 17.2 years, and 4 cases were atopic and one was non-atopic asthma. In previous publications, asthmatic symptoms were severe at the onset of the disease and progressed thereafter. In our 5 cases, however, the severities of bronchial asthma were mild of two cases, moderate of two and severe of only one, moreover severe asthmatic attacks were shown in only 2 cases when the manifestation of systemic vasculitis occurred. In conclusion, although CSS has been thought that one of complications of bronchial asthma, the occurrence of CSS are not necessarily correlated with symptoms of bronchial asthma.
