Abstract
65: Occup Med (Lond). 2005 Oct;55(7):572-4.
OBJECTIVES: The purpose of this study was to evaluate bronchoalveolar lavage fluid (BALF) components and Clara cell protein (CC16) concentration in serum and BALF in patients with glutaraldehyde (GA)-induced asthma, before and after a specific inhalatory provocation test (SIPT) with GA, in comparison to atopic asthmatics and healthy individuals.
METHODS: Spirometry and bronchoalveolar lavage were performed before and after SIPT. The serum and BALF concentrations of CC16 and cytogram content in BALF were evaluated.
RESULTS: In GA-sensitized asthmatics, the level of CC16 in BALF and serum was significantly lower at 24 h after SIPT in comparison with the values recorded prior to the experiment. There was a significant increase in the proportion of eosinophils, basophils and lymphocytes in BALF of GA-sensitized asthmatics obtained after SIPT.
CONCLUSIONS: The determination of CC16 either in serum or in BALF is a non-invasive test to detect Clara cell damage.
