[20] Smoking and other toxic fumes and gases should be avoided by all patients with bronchiectasis to decrease the development of infections (such as bronchitis) and further complications. The secondary purpose was to explore the relation between PACs and underlying pulmonary disease including upper lung fibrosis. 1), where the elastic and muscular tissue is destroyed by acute or chronic inflammation and infection. Bronchiectasis isn't one single disease. [38] Additionally, these impairments may be localized to the lungs, or systemic throughout the body. Bronchiectasis is an abnormal widening of one or more airways. [60] In this model, a predisposed individual develops an excessive inflammatory response to pulmonary infection or tissue injury.

The medical management of bronchiectasis includes a careful confirmation of the diagnosis based on clinical and computed tomography findings. In preventing bronchiectasis, it is necessary to prevent the lung infections and lung damage that can cause it. Look up information on diseases, tests, and procedures; then consult the database with 5,000+ drugs or refer to 65,000+ dictionary terms. [3] This triggers a host immune response from neutrophils (elastases), reactive oxygen species, and inflammatory cytokines that results in progressive destruction of normal lung architecture. People with bronchiectasis have periodic flare-ups of breathing difficulties, called exacerbations. Non-cystic fibrosis bronchiectasis: a type of bronchiectasis (permanent dilation of the airways of the lungs) that arises as a result of chronic inflammation and is not due to the genetic condition cystic fibrosis. [38], Some clinical trials have shown a benefit with inhaled bronchodilators in certain people with bronchiectasis. [57], A causal role for tobacco smoke in bronchiectasis has not been demonstrated. [3], The complications of bronchiectasis include serious health conditions, such as respiratory failure and atelectasis. Bacterial infections commonly associated with bronchiectasis include P. aeruginosa, H. influenzae, and S.

Bronchiectasis is the most common pulmonary manifestation associated with IBD, but in a study that involved 1258 patients from 7 European cohorts without cystic fibrosis, bronchiectasis was ascribed to IBD in only 1.9% of patients.4 In comparison, this was only slightly more frequent than bronchiectasis related to ciliary dysfunction and approximately a third of the cases due to immunodeficiency.
