Our study aimed to characterize the clinical significance and outcome of Aspergillus species isolated from lower-respiratory-tract samples of critically ill OVID-19 patients at a single center. Design: We conducted a retrospective cohort study to evaluate the characteristics of patients with COVID-19 and aspergillus isolated from the lower respiratory tract and to identify predictors of outcomes in this population. Setting: The setting was a single-center hospital system within the metropolitan Detroit region. Results: The prevalence of Aspergillus isolated in hospitalized COVID-19 patients was 1.18% (30\/2461 patients), and it was 4.6% in critically ill ICU patients with COVID-19. Probable COVID-19-associated invasive pulmonary aspergillosis (CAPA) was found in 21 critically ill patients, and 9 cases were classified as colonization. The in-hospital mortality of critically ill patients with CAPA and those with aspergillus colonization were high but not significantly different (76% vs. 67%, p = 1.00). Furthermore, the in-hospital mortality for ICU patients with or without Aspergillus isolated was not significantly different 73.3% vs. 64.5%, respectively (OR 1.53, CI 0.64\u20134.06, p = 0.43). In patients in whom Aspergillus was isolated, antifungal therapy (p = 0.035, OR 12.3, CI 1.74\u2013252); vasopressors (0.016, OR 10.6, CI 1.75\u201381.8); and a higher mSOFA score (p = 0.043, OR 1.29 CI 1.03\u20131.72) were associated with a worse outcome. In a multivariable model adjusting for other significant variables, FiO2 was the only variable associated with in-hospital mortality in patients in whom Aspergillus was isolated (OR 1.07, 95% CI 1.01\u20131.27). Conclusions: The isolation of Aspergillus from lower-respiratory-tract samples of critically ill patients with COVID-19 is associated with high mortality. It is important to have a low threshold for superimposed infections such as CAPA in critically ill patients with COVID-19.<\/jats:p>","DOI":"10.3390\/arm91050027","type":"journal-article","created":{"date-parts":[[2023,9,4]],"date-time":"2023-09-04T02:59:55Z","timestamp":1693796395000},"page":"337-349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Clinical Significance of Aspergillus Detected in Lower-Respiratory-Tract Samples of Critically Ill COVID-19-Positive Patients"],"prefix":"10.3390","volume":"91","author":[{"given":"Heba","family":"Osman","sequence":"first","affiliation":[{"name":"Department of Medicine and Pediatrics, Wayne State University School of Medicine, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0193-0651","authenticated-orcid":false,"given":"Asra N.","family":"Shaik","sequence":"additional","affiliation":[{"name":"Department of Medicine, Wayne State University School of Medicine, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul L.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Medicine, Wayne State University School of Medicine, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zachary","family":"Cantor","sequence":"additional","affiliation":[{"name":"Department of Medicine, Wayne State University School of Medicine, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5801-8818","authenticated-orcid":false,"given":"Mirna","family":"Kaafarani","sequence":"additional","affiliation":[{"name":"Division of Pulmonary, Critical Care and Sleep Medicine, Wayne State University School of Medicine, 3990 John R-3 Hudson, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0262-4365","authenticated-orcid":false,"given":"Ayman O.","family":"Soubani","sequence":"additional","affiliation":[{"name":"Division of Pulmonary, Critical Care and Sleep Medicine, Wayne State University School of Medicine, 3990 John R-3 Hudson, Detroit, MI 48201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,2]]},"reference":[{"key":"ref_1","unstructured":"Johns Hopkins Coronavirus Resource Center (2022, September 01).
