Bronchiolitis obliterans when it occurs following a lung transplant is known as bronchiolitis obliterans syndrome (BOS). [11] [4] BOS is defined as a person who has had either a HSCT or lung transplant and develops symptoms or radiographic findings consistent with bronchiolitis obliterans, but has not been confirmed by biopsy. [22] [44]
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. [2] [3] It is a form of idiopathic interstitial pneumonia. [4]
Chronic bronchiolitis is more common in adults and has various causes, one of which is bronchiolitis obliterans. [ 5 ] [ 6 ] Often when people refer to bronchiolitis, they are referring to acute bronchiolitis in children.
Bronchiolitis obliterans, also known as constrictive bronchiolitis or obliterative bronchiolitis is a respiratory disease caused by injury to the smallest airways, called bronchioles. It has been reported to occur from exposure to inhaled toxins and gases including sulfur mustard gas, nitrogen oxides, diacetyl (used in many food and beverage ...
Bronchiolitis (subgroup of chronic bronchitis) Bronchiole Inflammatory scarring and bronchiolitis obliterans: Tobacco smoking and air pollutants Cough, dyspnea Bronchiectasis: Bronchus: Dilation and scarring of airways Persistent severe infections Cough, purulent sputum and fever Asthma: Bronchus Smooth muscle hyperplasia; Excessive mucus ...
UIP=usual interstitial pneumonia; DAD=diffuse alveolar damage; NSIP=non-specific interstitial pneumonia; DIP=desquamative interstitial pneumonia; RB=respiratory bronchiolitis; BIP=bronchiolitis obliterans interstitial pneumonia; OP=organizing pneumonia; LIP=lymphoid interstitial pneumonia; LPD=lymphoproliferative disease (not considered a diffuse lung disease); GIP=giant cell interstitial ...
Swyer–James syndrome is a manifestation of postinfectious obliterative bronchiolitis. [2] In SJS, the involved lung or portion of the lung does not grow normally and is slightly smaller than the opposite lung. [ 3 ]
DPB and bronchiolitis obliterans are two forms of primary bronchiolitis. [2] Specific overlapping features of both diseases include strong cough with large amounts of often pus-filled sputum; nodules viewable on lung X-rays in the lower bronchi and bronchiolar area; and chronic sinusitis.
