Mechanisms of bronchial hyperreactivity in asthma and chronic obstructive pulmonary disease.
نویسندگان
چکیده
Bronchial hyperreactivity has long been recognized as a hallmark of chronic asthma. Less is known about the prevalence and mechanisms of hyperreactivity in chronic obstructive pulmonary disease (COPD). Currently, it is unclear whether the role and mechanisms of hyperreactivity are similar in patients with asthma and COPD or whether the underlying pathophysiologic abnormalities are different for both diseases. The aim of this review is to present an overview of current knowledge of the mechanisms of bronchial hyperreactivity in asthma and COPD.

Overlap Syndrome in Respiratory Medicine: Asthma and Chronic Obstructive Pulmonary Disease
Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with o...
متن کاملEffect of inhaled corticosteroids on small airway inflammation in patients with bronchial asthma.
Bronchial asthma is a chronic inflammatory disease affecting the bronchial mucosa. In asthma patients, the highest number of inflammatory cells, including eosinophils, are found in the small bronchi. According to the most recent 2006 report of the Global Initiative for Asthma, inhaled corticosteroids (ICS) remain the first-line treatment of chronic asthma. They are characterized by high lung de...

Introduction Polymorphonuclear eosinophil leucocytes (eosinophils) are found in increased numbers in the circulation and sputum in asthma patients, usually in relation to the severity of asthma but it is the question whether they have a significant role in the development and level of bronchial hyperreactivity in patients with chronic obstructive pulmonary disease (COPD). Objective to show th...
متن کاملAdenosine, methacholine, and exercise challenges in children with asthma or paediatric chronic obstructive pulmonary disease.
BACKGROUND Bronchial hyperreactivity to methacholine is present in children with asthma and other types of paediatric chronic obstructive pulmonary disease (COPD), while hyperreactivity to exercise is more specific for asthma. Adenosine 5'-monophosphate (AMP) is a potent bronchoconstrictor and, like exercise, may provoke asthma by activating mast cells. This study investigated the suitability o...
متن کاملBronchial hyperresponsiveness: the need for a distinction between hypersensitivity and excessive airway narrowing.
Bronchial hyperresponsiveness is currently defined as an increase in sensitivity to a wide variety of airway narrowing stimuli. Most patients with asthma and chronic obstructive pulmonary disease (COPD) exhibit such an enhanced sensitivity. In asthma, in particular, this hypersensitivity is accompanied by excessive degrees of airway narrowing. This raises the question as to whether measures of ...
