What is reactive small airway disease?
People with reactive airway disease have bronchial tubes that overreact to some sort of irritant. The term is most commonly used to describe a person who is wheezing or having a bronchial spasm, but who has not yet been diagnosed with asthma.
What causes small airway inflammation?
We chose to focus on the major causes of small airways disease including airway infections, connective tissue diseases and inflammatory bowel diseases, bone marrow and lung transplantation, immune deficiencies, diffuse panbronchiolitis, and diseases related to environmental exposures to pollutants, allergens and drugs.
What is small airway inflammation?
The small airway inflammation may cause an uncoupling of the parenchyma and airways due to the mechanical interdependence between these two compartments, leading to changes in overall lung mechanics in asthmatic persons. Those results have therapeutic as well as diagnostic implications.
Is small airway disease treatable?
Emphysema is a condition in which the alveoli at the end of the smallest air passages (bronchioles) of the lungs are destroyed as a result of damaging exposure to cigarette smoke and other irritating gases and particulate matter. Although COPD is a progressive disease that gets worse over time, COPD is treatable.

Is small airway disease reversible?
Background. Asthma is a common, heterogeneous disorder characterized as a chronic inflammatory disease of the airways with bronchial hyperresponsiveness to a variety of stimuli, and variable airflow limitation that is often reversible either spontaneously or as a result of therapy [1].
When do you have reactive airway disease?
Conditions included in this group of diseases. Anytime you have difficulty breathing from your bronchial tubes, swelling, and overreaction to an irritant, it can be referred to as reactive airway disease. It’s usually the term used prior to an actual diagnosis of asthma. Reactive airway disease may also sometimes be used when discussing COPD.
What are the radiological features of small airways disease?
There are many CT features associated with small airways disease which include: 1. Sharma V, Shaaban AM, Berges G et-al. The radiological spectrum of small-airway diseases. Semin. Ultrasound CT MR. 2003;23 (4): 339-51. Pubmed citation 2. Tasker AD, Flower CD. Imaging the airways. Hemoptysis, bronchiectasis, and small airways disease. Clin.
How is reactive airway disease similar to COPD?
Reactive airway disease may also sometimes be used when discussing COPD. Whether this term should be used interchangeably with asthma or COPD is debated among some medical professionals. The symptoms of reactive airway disease are similar to those of asthma.
How are small airways related to total airway resistance?
In normal lungs, small airways contribute only a little to total airway resistance [ 6 ], and it has been estimated that obstruction of 75% of all small airways is required before changes can be detected by routine pulmonary function tests ( e.g. forced expiratory volume in 1 s (FEV 1 )) [ 7 ].
What does it mean to have reactive airway disease?
Reactive airway disease is a term used to describe a set of symptoms that indicate a person is having a bronchial spasm. This is a reaction in their airway that needs further investigation.

Is there such thing as reversible airway narrowing?
The problem is that it is not a medical term, per se, and has different definitions depending on who you speak to. Some doctors will use RAD to describe diseases that cause reversible airway narrowing, while others will include COPD, which is clearly not reversible.
