Obliterative bronchiolitis

Bronchiolitis obliterans is an inflammatory condition that affects the lung's tiniest airways, the bronchioles. In affected people, the bronchioles may become damaged and inflamed leading to extensive scarring that blocks the airways. Signs and symptoms of the condition include a dry cough; shortness of breath; and/or fatigue and wheezing in the.

A picture is worth a thousand words (but an augmented reality hyperphoto is worth a 1000 words and a short video Obliterative bronchiolitis is potentially an under-recognised late complication in patients after kidney transplantation. Keywords. obliterative bronchiolitis, bronchiolitis obliterans syndrome, kidney transplant. Abbreviations Abstract Obliterative bronchiolitis (OB) is a clinical syndrome marked by progressive dyspnea and cough with the absence of parenchymal lung disease on radiographic studies. Pulmonary function testing reveals an obstructive ventilatory defect that is typically not reversed by inhaled bronchodilator. Transbronchial biopsies are insufficiently sensitive to achieve diagnosis, and in most cases. Over the last decade, improvements in surgical techniques, lung preservation, immunosuppression, and management of ischaemia/reperfusion injury and infections have made intermediate-term survival after lung transplantation an achievable goal. However, chronic allograft dysfunction in the form of bronchiolitis obliterans remains a major hurdle that threatens both the quality of life and long.
