Bronchial reactivity and airflow obstruction in rheumatoid arthritis.
OBJECTIVES To investigate the prevalence of airways obstruction and bronchial reactivity to inhaled methacholine in rheumatoid arthritis patients and unselected controls. The control population consisted of patients attending the rheumatology department for minor degenerative joint problems. METHODS One hundred patients with rheumatoid arthritis (RA) [72 (72%) women, 28 (28%) men; mean (SD) a...
متن کاملAspects of chronic airflow obstruction.
This report questions several commonly used definitions and commonly accepted concepts. It suggest that the term, "chronic airflow obstructions," should replace the terms, "chronic obstructive pulmonary disease," "chronic obstructive lung disease," or "chronic airway obstruction," because it is flow that is obstructed. It is suggested the term, "chronic mucous hypersecretion," be used, rather t...
متن کاملBronchial responsiveness to methacholine in chronic bronchitis: relationship to airflow obstruction and cold air responsiveness.
The response to inhaled methacholine is increased in patients with chronic airflow obstruction, but it is not known whether this is due to true hyperresponsiveness or is a result of the airflow obstruction. In asthmatics the response to methacholine correlates with the bronchoconstriction produced by hyperventilation of cold dry air. We studied 27 patients with a history of smoking and chronic ...
متن کاملBronchial responsiveness, lung mechanics, gas transfer, and corticosteroid response in patients with chronic airflow obstruction.
Thirty patients with stable chronic airflow obstruction receiving regular bronchodilator treatment were studied to determine whether the level of bronchial responsiveness, transfer factor for carbon monoxide (TLCO), or the mechanical properties of the lung predicted a bronchodilator response to oral corticosteroid treatment. Before treatment mean (SD) FEV1 was 48% (16%) of the predicted value (...
متن کاملSmoking, asthma, chronic airflow obstruction and COPD.
Cigarette smoking is the most prevalent risk factor for the development of adult-onset respiratory diseases associated with airflow obstruction, namely emphysema and chronic bronchitis, commonly called chronic obstructive pulmonary disease (COPD). Regrettably, childhood asthma does not reduce the likelihood of initiation of smoking [1] but it is not fully clear how smoking impacts pre-existing ...
