FEV1 decline in occupational asthma.
BACKGROUND In occupational asthma continued workplace exposure to the causative agent is associated with a poor prognosis. However, there is little information available on how rapidly lung function declines in those who continue to be exposed, nor how removal from exposure affects lung function. METHODS Forced expiratory volume in 1 second (FEV1) was studied in 156 consecutive subjects with ...
متن کاملSputum eosinophilia is a determinant of FEV1 decline in occupational asthma: results of an observational study
OBJECTIVE To evaluate the potential determinants of forced expiratory volume in 1 s (FEV1) decline in workers with occupational asthma (OA) still exposed to the causative agent. We hypothesised that sputum eosinophilia might be a predictor of poor asthma outcome after diagnosis. SETTING, DESIGN AND PARTICIPANTS In a specialistic clinical centre of the University Hospital of Pisa, we studied 3...
متن کاملFEV1 decline in cystic fibrosis.
I read the paper by Taylor-Robinson et al with interest with regard to modelling the decline in forced expiratory volume in 1 second (FEV1) in patients with cystic fibrosis (CF). The authors have made the assumption that expressing spirometry results as a per cent of predicted (PP) is a valid way to use lung function over a wide age range. Young adult patients with cystic fibrosis die with abso...
متن کاملDecline in FEV1 and airflow limitation related to occupational exposures in men of an urban community.
The purpose of this survey was to evaluate the effects of smoking and occupational exposures on the decline in forced expiratory volume in one second (FEV1), and the presence of airflow limitation (FEV1 x100/forced vital capacity (FVC) being < 65) at follow-up. A random sample of 1,933 men aged 22-54 years in Bergen, Norway, were invited into the survey. Smoking habits and measurements of FEV1 ...
متن کاملBronchial responsiveness and decline in FEV1 in aluminium potroom workers.
We have investigated the relationship between annual decline in forced expiratory volume in one second (delta FEV1) and bronchial responsiveness (BR) in aluminium potroom workers. BR was measured in a cross-sectional study of 337 aluminium potroom workers half-way through a 6 yr follow-up study of lung function. A skin-prick test (SPT) was also performed. During follow-up the mean number of mea...
