    However, in asthma, the airflow limitation usually completely resolves after exacerbations, whereas in COPD it may not. [1] ACO presents with a chronic airflow limitation or obstruction (due to inflammation), with characteristics of both asthma and COPD. Inflammation of the large and medium airways (classically seen with asthma) is seen in ACO. [1]

    Acute severe asthma, also known as status asthmaticus, is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators (inhalers) and corticosteroids. [2] Asthma is caused by multiple genes , some having protective effect, with each gene having its own tendency to be influenced by the environment although a ...

    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.

    Cigarette smoking can increase the risk or make the illness worse. [7] Smoking is a known cause of some types of lung fibrosis, such as smoking-related interstitial fibrosis (SRIF). [11] Some typical connective tissue diseases [7] such as rheumatoid arthritis, ankylosing spondylitis, SLE and scleroderma

  8. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    This has suggested that an underlying mechanism related to HIV is a contributory factor in the development of emphysema. HIV associated emphysema occurs over a much shorter time than that associated with smoking; an earlier presentation is also seen in emphysema caused by alpha-1 antitrypsin deficiency. Both of these conditions predominantly ...

  9. Occupational asthma - Wikipedia

    en.wikipedia.org/wiki/Occupational_asthma

    Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.
