Idiopathic Bronchiolitis Obliterans With Organizing Pneumonia

Cryptogenic organising pneumonia

“…Although hypoxaemia with alveolar right-to-left shunt may be well tolerated as mentioned previously, other patients may require mechanical ventilation (noninvasive or with tracheal intubation) or progress to death, especially when corticosteroid treatment is delayed [400,401]. This occurs particularly in patients with delayed diagnosis who may improve once corticosteroid treatment is given (sometimes in association with immunosuppressive agents when corticosteroid resistance is suspected) [248,[402][403][404][405][406][407].…”

Bronchiolitis Obliterans with Organising Pneumonia presenting as Non Resolving Pneumonia

“…BOOP may also present as solitary pulmonary nodule, with or without cavitation or linear basal opacities, and may be unilateral. BOOP has also been reported to be of acute onset and progressive in course making it indistinguishable from acute interstitial pneumonia or may have an acute onset and an indolent course thereafter as in our case [8]. BOOP is also a reversible cause of respiratory failure, responsive to steroids therapy when it presents as diffuse acute interstitial pneumonia [9].…”

A novel cause for bronchiolitis obliterans organizing pneumonia: exposure to paint aerosols in textile workshops

“…Regarding the latter aspect, the cases described by ROMERO et al [1] resemble severe BOOP cases [4,35], as reported in the context of rheumatoid arthritis [36], polymyositis [37], scleroderma [38] or following exposure to such drugs as penicillamine [38] or nitrofurantoin [37]. The lack of response to steroids or cyclophosphamide in these cases, as well as in some of those described by ROMERO et al [1] is intriguing, and contrasts with classic BOOP [3][4][5]39].…”
