Blood avian precipitins were strongly positive. Lung function testing confirmed a restrictive pattern with impaired gas transfer. A \u2018ground glass\u2019 mosaic pattern was seen on CT imaging, suggestive of hypersensitivity pneumonitis. Although he had no pet birds, on closer questioning he had recently acquired a duvet and pillows containing feathers. His symptoms, chest radiograph and lung function tests improved after removal of all feather bedding, and he was also started on oral corticosteroid therapy. Our case reinforces the importance of taking a meticulous exposure history and asking about domestic bedding in patients with unexplained breathlessness. Prompt recognition and cessation of antigen exposure may prevent the development of irreversible lung fibrosis.<\/jats:p>","DOI":"10.1136\/bcr-2019-231237","type":"journal-article","created":{"date-parts":[[2019,11,18]],"date-time":"2019-11-18T23:59:13Z","timestamp":1574121553000},"page":"e231237","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Feather duvet lung"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3005-7580","authenticated-orcid":false,"given":"Patrick","family":"Liu-Shiu-Cheong","sequence":"first","affiliation":[{"name":"Respiratory Medicine, Victoria Hospital, Kirkcaldy, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chris RuiWen","family":"Kuo","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Aberdeen Royal Infirmary, Aberdeen, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Struan WA","family":"Wilkie","sequence":"additional","affiliation":[{"name":"Radiology, Aberdeen Royal Infirmary, Aberdeen, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Owen","family":"Dempsey","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Aberdeen Royal Infirmary, Aberdeen, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,11,18]]},"reference":[{"key":"2025082712372041000_12.11.e231237.1","unstructured":"@BBCNews .
