Endobronchial ultrasound\u2010guided transbronchial lung biopsy (EBUS\u2010TBLB) improves tissue acquisition for peripheral lesions, whereas metagenomic next\u2010generation sequencing (mNGS) offers culture\u2010independent pathogen detection. Whether their combination enhances etiological clarification of NRP remains uncertain.\n <\/jats:p>\n \n Methods:<\/jats:bold>\n A total of 109 consecutive adults with NRP unresponsive to standard antimicrobial therapy were randomized to EBUS\u2010TBLB alone (\n n<\/jats:italic>\n \u2009=\u200966) or EBUS\u2010TBLB\u2009+\u2009mNGS (\n n<\/jats:italic>\n \u2009=\u200943). Baseline characteristics, diagnostic yield, and procedure\u2010related complications were recorded. Diagnostic positivity, sensitivity for infectious agents, and safety profiles were compared using\n \u03c7<\/jats:italic>\n 2<\/jats:sup>\n or Fisher\u2019s exact tests, with\n p<\/jats:italic>\n < 0.05 considered significant.\n <\/jats:p>\n \n Results:<\/jats:bold>\n Overall diagnostic yield increased from 50.0% with EBUS\u2010TBLB to 72.1% with the combined approach (\n \u03c7<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u20094.37,\n p<\/jats:italic>\n < 0.05). mNGS significantly improved detection of bacterial\/fungal pneumonia (0% vs. 13.9%;\n p<\/jats:italic>\n < 0.05) and pulmonary\n tuberculosis<\/jats:italic>\n (0% vs. 20.9%;\n p<\/jats:italic>\n < 0.05). Malignancy remained the predominant diagnosis (57.8% of all cases); yields for most tumor subtypes were comparable between groups. Complication rates did not differ between the two groups: minor bleeding (19.7% vs. 23.3%), hypoxia (50.0% vs. 48.8%), pneumothorax (4.5% vs. 0%), and delayed recovery (4.5% vs. 7.0%) (\n p<\/jats:italic>\n > 0.05). No severe adverse events occurred.\n <\/jats:p>\n \n Conclusions:<\/jats:bold>\n EBUS\u2010TBLB\u2009+\u2009mNGS represents a paradigm shift in the diagnosis of complex respiratory cases, integrating imaging with advanced genomics to enhance precision medicine. In practice, early implementation of the EBUS\u2010TBLB\u2009+\u2009mNGS diagnostic protocol in patients with NRP can help exclude malignancy or confirm an infectious etiology.\n <\/jats:p>","DOI":"10.1155\/carj\/7651699","type":"journal-article","created":{"date-parts":[[2025,8,29]],"date-time":"2025-08-29T07:35:42Z","timestamp":1756452942000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Improved Etiological Diagnosis of Nonresolving or Slowly Resolving Pneumonia Through Combined Endobronchial Ultrasound\u2010Guided Biopsy and Metagenomic Sequencing"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-4420-3567","authenticated-orcid":false,"given":"Qiang","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8108-3797","authenticated-orcid":false,"given":"Li","family":"Jian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1255-4660","authenticated-orcid":false,"given":"Qiquan","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,29]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0272-5231(05)70241-0"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2023.1204024"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1993.00410040054008"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/mcp.0000000000000588"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eimce.2024.07.001"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eimce.2024.11.002"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.heliyon.2024.e35802"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2024.1295184"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1136\/thx.47.7.565"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.115.6.1500"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.slast.2024.100198"},{"key":"e_1_2_12_12_2","doi-asserted-by":"publisher","DOI":"10.4103\/eus.eus_48_17"},{"key":"e_1_2_12_13_2","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/2367505"},{"key":"e_1_2_12_14_2","doi-asserted-by":"publisher","DOI":"10.2147\/idr.s335864"},{"key":"e_1_2_12_15_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-024-09761-8"},{"key":"e_1_2_12_16_2","doi-asserted-by":"publisher","DOI":"10.21037\/jtd-21-369"},{"key":"e_1_2_12_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/crj.13746"}],"container-title":["Canadian Respiratory Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/carj\/7651699","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/carj\/7651699","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/carj\/7651699","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T17:33:58Z","timestamp":1772991238000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/carj\/7651699"}},"subtitle":[],"editor":[{"given":"Xi-Qian","family":"Xing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":17,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/carj\/7651699"],"URL":"https:\/\/doi.org\/10.1155\/carj\/7651699","archive":["Portico"],"relation":{},"ISSN":["1198-2241","1916-7245"],"issn-type":[{"value":"1198-2241","type":"print"},{"value":"1916-7245","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2025-05-22","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-21","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-29","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"7651699"}}
