for up to 20% of idiopathic cases. Even heterozygous patients, who typically have no clinical manifestations of CF, may have an increased risk of bronchiectasis. Immunodeficiencies such as (CVID) may also lead to diffuse disease, as may rare abnormalities in airway structure. Undernutrition and HIV infection also appear to increase risk. Congenital defects in mucociliary clearance such as primary ciliary dyskinesia (PCD) syndromes may also be a cause, explaining almost 3% of previously idiopathic (...) cases. Diffuse bronchiectasis sometimes complicates common autoimmune disorders, such as RA or Sjögren syndrome, and can occur in the setting of hematologic malignancy, organ transplant, or due to the immune compromise associated with treatment in these conditions. , a hypersensitivity reaction to Aspergillus spp that occurs most commonly in people with asthma, but sometimes in patients with CF, can cause or contribute to bronchiectasis.
