Overview
Bronchiectasis can be caused by both, congenital and acquired factors. Congenital factors include conditions such as Kartagener syndrome and Young's syndrome. Acquired factors include tuberculosis infections such as endobronchial tuberculosis as well as inflammatory bowel diseases like ulcerative colitis and Crohn's disease.
Causes
Congenital
- A small number of patients develop severe localized bronchiectasis in this disease.[2]
- This disease is clinically similar to cystic fibrosis and is thought to significantly contribute to the development of bronchiectasis.
- This disease has been found to those particularly susceptible to bronchiectasis, for unknown reasons. [4]
- Other less-common congenital causes are primary immunodeficiencies
- These are due to the weakened or nonexistent immune system response to severe, recurrent infections that commonly affect the lung.[5]
Acquired
Bronchiectasis from these causes occur more frequently.
- Endobronchial tuberculosis commonly leads to bronchiectasis, either from bronchial stenosis or secondary traction from fibrosis.
- This stems from the human immunodeficiency virus
- This disease predisposes patients to a variety of pulmonary ailments, such as pneumonia and other opportunistic infections.[6]
- This is especially with ulcerative colitis. It can occur in Crohn's disease as well, but does so less frequently.
- Bronchiectasis in this situation usually stems from various allergic responses to inhaled fungus spores.[7]
- One study showed a tenfold increase in the prevalence of the disease in this patients who smoke.[8] Still, it is unclear as to whether or not cigarette smoke is a specific primary cause of bronchiectasis.
- Other acquired causes are
- Environmental exposures including respiratory infections
- obstructions
- Inhalation and aspiration of ammonia and other toxic gases
- pulmonary aspiration
- Alcoholism
- Heroin (drug use)
- Various allergies[9]
