Sputum induction (IS) can be used to study airway inflammation in asthmatics and other lung diseases. However, no data are available for patients with Churg-Strauss syndrome (CSS). A study was carried out to evaluate eosinophil counts and eosinophil cationic protein (ECP) levels in induced sputum during the follow-up of three patients with CSS. Induced sputum was carried out in 10 patients with corticosteroid-dependent asthma (used as a control group). Patients with CSS had significantly higher eosinophils percentages and ECP levels in sputum than those with stable corticosteroid-dependent asthma. During the follow-up, patients with CSS presented increased ECP levels sputum and eosinophils in sputum as well as increased blood eosinophils, despite their oral corticosteroid and immunosuppressive treatment. Eosinophil percentage in sputum and the total number of eosinophils in peripheral blood were more predictive of exacerbations of CSS than sputum ECP.

D005938 Glucocorticoids A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.
