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 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 کاملExacerbation frequency and FEV1 decline of COPD: is it geographic?
Chronic obstructive pulmonary disease (COPD) exacerbations are episodes of symptom worsening that have major impacts on a variety of health outcomes, including quality of life, hospital admission and death [1]. Exacerbation reduction is now a key outcome for pharmacological therapies in COPD and, thus, if exacerbation can be prevented how does this affect disease progression and lung function d...
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...
متن کاملObstructive sleep apnoea accelerates FEV1 decline in asthmatic patients
BACKGROUND Although the prevalence of both obstructive sleep apnoea (OSA) and asthma are both increasing, little is known about the impact of OSA on the natural history of lung function in asthmatic patients. METHODS A total of 466 patients from our sleep laboratory were retrospectively enrolled. Of them, 77 patients (16.5%) had asthma with regular follow-up for more than 5 years. Their clini...
