The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...
Bronchial hyperresponsiveness is a hallmark of asthma but also occurs frequently in people with chronic obstructive pulmonary disease (COPD). [2] In the Lung Health Study, bronchial hyperresponsiveness was present in approximately two-thirds of patients with non-severe COPD, and this predicted lung function decline independently of other ...
Bronchial thermoplasty is the only treatment modality designed to combat a hallmark of airway remodelling; airway smooth muscle hypertrophy. The effects of bronchial thermoplasty on smooth muscle mass are seen up to at least 12 months post-treatment; however, the procedure does not seem to impact other features of airway remodelling. [4]
In a clinical study, bronchial thermoplasty has been proven to provide long-term reduction in asthma induced breathing difficulty to at least 5 years and improve the quality of life for severe persistent asthma patients. [7] Reduction in asthma attacks, ER visits, and hospitalizations for respiratory symptoms are maintained to at least 5 years. [8]
They are elongated microscopic mucous casts from small bronchi and are often found in sputum samples from patients with bronchial asthma. They can be stretched out to a length of around 2 cm and can sometimes be longer. They have a central core that may be ensheathed in cell debris and mucus. [3]
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of respiratory airways. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace. Exposure to ...
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
