Bronchoalveolar lavages (BALs, N = 103) from patients with haematological\/oncological underlying diseases were retrospectively investigated. The performance of three PCR assays, namely MycoGENIE\u00aeAspergillus fumigatus Real-Time PCR Kit (Adamtech), Fungiplex\u00aeAspergillus Azole-R IVD Real-Time PCR Kit (Bruker Daltonik GmbH) and AsperGenius\u00ae (PathoNostics B.V.), were evaluated. All patients were categorised following current EORTC\/MSG criteria, with exclusion of the PCR-results. From the 11 invasive pulmonary aspergillosis (IPA) probable samples, eight were detected with MycoGENIE\u00ae, resulting in a sensitivity of 80% and a specificity of 73%. Furthermore, Fungiplex\u00ae resulted in six positive BALs with a sensitivity of 60% and a specificity of 91% and AsperGenius\u00ae in seven positive BAL samples, with a sensitivity of 64% and a specificity of 97%. No proven IPA was detected. One isolate showed phenotypically an azole-resistance, which was also detected in each of the tested PCR assays with the mutation in TR34. The here tested PCR assays were capable of reliably detecting A. fumigatus DNA, as well as differentiation of the common cyp51A gene mutations. However, evaluation on the AsperGenius\u00ae assay revealed a low risk of false positive results.<\/jats:p>","DOI":"10.3390\/jof7020132","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T16:12:10Z","timestamp":1613146330000},"page":"132","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Evaluation of Three Commercial PCR Assays for the Detection of Azole-Resistant Aspergillus fumigatus from Respiratory Samples of Immunocompromised Patients"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7689-7799","authenticated-orcid":false,"given":"Ulrike","family":"Scharmann","sequence":"first","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2015-275X","authenticated-orcid":false,"given":"Lisa","family":"Kirchhoff","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Hain","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Buer","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8738-5884","authenticated-orcid":false,"given":"Michael","family":"Koldehoff","sequence":"additional","affiliation":[{"name":"Department of Hematology and Stem Cell Transplantation, West German Cancer Centre, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joerg","family":"Steinmann","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"},{"name":"Institute of Clinical Hygiene, Medical Microbiology and Infectiology, Klinikum N\u00fcrnberg, Paracelsus Medical University, 90419 Nuremberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter-Michael","family":"Rath","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology, University Hospital Essen, University of Duisburg-Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1007\/BF01967060","article-title":"Fungal infections in cancer patients: An international autopsy survey","volume":"11","author":"Bodey","year":"1992","journal-title":"Eur.
