title: [Relationship between presence of Creola bodies and airway hyperresponsiveness in patients with bronchial asthma].
abstract: It has recently been suggested that epithelial damage participates in the development of bronchial hyperresponsiveness. In this study we investigated the relationship between the presence of clusters of desquamated respiratory epithelial cells (Creola body. CrB) in sputum and airway responsiveness. Sputa were collected from asthmatic patients and acetylcholine inhalation tests were performed to assess airway responsiveness. Smears of 100 microliters of sputum were spread in pairs of two glass slides. One slide was stained with Papanicolaou's stain, the other with Giemsa stain. CrBs were detected on the whole glass slide stained with Papanicolaou's stain and the CrB score was determined by summing up the points given to each CrB on a glass slide according to the number of epithelial cells composing one CrB. The CrB score was significantly higher in patients with CrBs than in patients without CrBs. The patients with higher CrB score (CrB score greater than or equal to 6) had significantly greater number of eosinophils in sputa than the patients without CrBs. These results suggest the participation of damage to the respiratory epithelium in the development of airway hyperresponsiveness in bronchial asthma. The detection of CrBs is easy and we consider it clinically useful in the estimation of airway hyperresponsiveness.
