Bronchiolitis obliterans (BO) is a rare, chronic form of obstructive lung disease, often initiated with injury of the bronchiolar epithelium followed by an inflammatory response and progressive fibrosis of small airways resulting in nonuniform luminal obliteration or narrowing.

This study shows that the radiologic findings of bronchiolitis obliterans include alveolar opacities without lung-volume loss. @oakbourne, I have added this discussion that you started about bronchiolitis obliterans with organizing pneumonia (BOOP) to the Lung group as well.There are several discussions about BOOP, also called Cryptogenic Organizing Pneumonia (COP), in the Lung Health group that you may wish to join. Four patients presented with respiratory failure requiring respiratory assistance and positive pressure ventilation. CONCLUSION Post-infectious bronchiolitis obliterans is a disease with a high morbidity rate; it should be treated by a multidisciplinary team, and patients should be followed up for a long period of time. – Bronchiolitis obliterans (BO) is a graft-versus-host disease of respiratory organs. should be mentioned elsewhere if so). This condition is pretty frequent in the winters. Directions to Hospitals Treating Bronchiolitis obliterans. The penicillamine-related bronchiolitis obliterans has a poor prognosis, sometimes requiring lung transplantation for management. OB is not the same disorder as bronchiolitis obliterans organizing pneumonia (BOOP), now known as cryptogenic organizing pneumonia (COP), which is a treatable disorder with a favorable prognosis. Although much attention is focused on the life threatening acute cutaneous and sight threatening ocular manifestations of this disease, chronic pulmonary complications like bronchiolitis obliterans are occasionally encountered. Presented by Peter Illei, M.D. - Bronchiolitis obliterans (BO) is a graft-versus-host disease of respiratory organs. Bronchiolitis obliterans is an inflammatory condition that affects the lung's tiniest airways, the bronchioles.

This report describes five patients with a fulminating and life-threatening variant of this syndrome. Abstract: Bronchiolitis obliterans syndrome (BOS) had been considered to be the representative form of chronic rejection or chronic lung allograft dysfunction (CLAD) after lung transplantation. As stated, Bronchiolitis is a pathological condition of the lungs found in children and infants in which the bronchioles get congested due to a viral infection. The prognosis for people who experience constrictive bronchiolitis obliterans is often times poor. Bronchiolitis obliterans organizing pneumonia is an inflammatory reaction with a variety of causes. Despite lung transplantation being a possible cause of bronchiolitis, treatment with a lung transplant may be considered when the condition is caused by toxin exposure. Key words: bronchiolitis obliterans organizing pneumonia, cryp-togenic organizing pneumonia, interstitial lung disease, drug-induced pneumonitis. Some evidence shows vaping may also lead to popcorn lung. Bronchiolitis obliterans syndrome (BOS), defined as staged decline in pulmonary function has proved a reproducible and sensitive marker of obliterative bronchiolitis. 40 Fatal bronchiolitis obliterans has been reported in a 12-year-old girl with juvenile rheumatoid arthritis after a 6-month course of intramuscular gold.

The clinical aspects and treatment of chronic rejection appearing in the form of bronchiolitis obliterans (BO) and bronchiolitis obliterans syndrome (BOS) are discussed here. Clinicians frequently encounter pathology reports of OP in patients with no underlying condition (cryptogenic OP, also known as BOOP or bronchiolitis obliterans OP) or in association with drugs or nonpulmonary disease. Bronchiolitis obliterans organizing pneumonia (BOOP) is a chronic respiratory disease. bronchiolitis obliterans, the current understanding of the pathogenesis of bronchiolitis obliterans based on results of animal and human studies, the clinical staging of the complication, strategies that may contribute to the prevention and/or early detection of bronchiolitis obliterans, …
