Bronchospasm or a bronchial spasm is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release ( degranulation ) of substances from mast cells or basophils under the influence of anaphylatoxins .
The most common cause of emphysema is smoking and smoking cessation is mandatory if this incurable disease is to be treated. Prevention of bronchoconstriction by this pathway is vital for people with emphysema and there are several anticholinergic medications that in combination with mucous thinning agents such as Guaifenesin cause significant ...
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 ...
GERD may be common in difficult-to-control asthma, but according to one study, treating it does not seem to affect the asthma. [33] When there is a clinical suspicion for GERD as the cause of the asthma, an Esophageal pH Monitoring is required to confirm the diagnosis and establish the relationship between GERD and asthma.
ABPA should be suspected in patients with a predisposing lung disease—most commonly asthma or cystic fibrosis— and is often associated with chronic airway limitation (CAL). Patients generally present with symptoms of recurrent infection such as fever, but do not respond to conventional antibiotic therapy. Poorly controlled asthma is a ...
AERD affects an estimated 0.3–0.9% of the general population in the US, including around 7% of all asthmatics, about 14% of adults with severe asthma, and ~5-10% of patients with adult onset asthma. [2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]
Approximately 17% of all adult-onset asthma cases are related to occupational exposures. [21] About one fourth of adults with asthma have work-exacerbated asthma. [4] Patients with work-related asthma are more likely to experience asthma attacks, emergency room visits, and worsening of their asthma symptoms compared with other adult asthma ...
The cause for acute severe asthma attacks is still unknown and experts are also unsure of why it developed and why it does not respond to typical asthma treatments.
