Med."],"abstract":"<jats:p>Acute and chronic eosinophilic pneumonia (AEP and CEP) include a group of rare interstitial lung diseases characterized by peripheral blood eosinophilia, increased eosinophils in bronchoalveolar lavage fluid, or eosinophilic infiltration of lung parenchyma. AEP is characterized by rapid onset, fast response to steroid treatment, and no relapse. CEP is characterized by marked tissue and peripheral blood eosinophilia, rapid response to steroid therapy, and tendency to disease recurrence. In addition, we briefly describe other eosinophilic lung diseases that must be considered in differential diagnosis of AEP and CEP. Eosinophilic pneumonias may be idiopathic or due to known causes such as medications or environmental exposure. At variance with previous reviews on this topic, a particular look in this overview was directed at pathological findings and radiological patterns.<\/jats:p>","DOI":"10.3389\/fmed.2024.1355247","type":"journal-article","created":{"date-parts":[[2024,4,22]],"date-time":"2024-04-22T00:51:15Z","timestamp":1713747075000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":41,"title":["Acute and chronic eosinophilic pneumonia: an overview"],"prefix":"10.3389","volume":"11","author":[{"given":"Roberto G.","family":"Carbone","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Puppo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Mattar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anja C.","family":"Roden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikhil","family":"Hirani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,22]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"379","DOI":"10.1016\/j.chest.2017.03.001","article-title":"Acute eosinophilic pneumonia: correlation of clinical characteristics with underlying cause","volume":"152","author":"De Giacomi","year":"2017","journal-title":"Chest"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"569","DOI":"10.1056\/NEJM198908313210903","article-title":"Acute eosinophilic pneumonia as a reversible cause of noninfectious respiratory failure","volume":"321","author":"Allen","year":"1989","journal-title":"N Engl J Med"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"797","DOI":"10.1164\/rccm.200206-576OC","article-title":"Acute eosinophilic pneumonia in a New York city firefighter exposed to world trade center dust","volume":"166","author":"Rom","year":"2002","journal-title":"Am J Respir Crit Care Med"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"2997","DOI":"10.1001\/jama.292.24.2997","article-title":"Acute eosinophilic pneumonia among US military personnel deployed in or near Iraq","volume":"292","author":"Shorr","year":"2004","journal-title":"JAMA"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"315","DOI":"10.1016\/j.amjms.2022.10.003","article-title":"A comparative analysis of acute eosinophilic pneumonia associated with smoking and vaping","volume":"365","author":"Bonnier","year":"2023","journal-title":"Am J Med Sci"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"960","DOI":"10.1056\/NEJMe1912032","article-title":"Vaping-induced acute lung injury","volume":"382","author":"Christiani","year":"2020","journal-title":"N Engl J Med"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"847","DOI":"10.2169\/internalmedicine.31.847","article-title":"Acute and chronic eosinophilic pneumonia: clinical evaluation and the criteria","volume":"31","author":"Umeki","year":"1992","journal-title":"Intern Med"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1007\/978-1-4471-2401-6_15","article-title":"Eosinophilic pneumonia","volume-title":"Orphan Lung Diseases: A Clinical Guide to Rare Lung Disease","author":"Cottin","year":"2015"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"1235","DOI":"10.1164\/rccm.2112056","article-title":"Idiopathic acute eosinophilic pneumonia: a study of 22 patients","volume":"166","author":"Philit","year":"2002","journal-title":"Am J Respir Crit Care Med"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"462","DOI":"10.1016\/j.ejrad.2007.04.012","article-title":"Acute eosinophilic pneumonia: thin-section CT findings in 29 patients","volume":"65","author":"Daimon","year":"2008","journal-title":"Eur J Radiol"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"334","DOI":"10.1097\/00005792-199611000-00004","article-title":"Acute eosinophilic pneumonia.
