These syndromes often mimic infections, leading to delayed diagnosis and inappropriate treatment. Acute complications include peri-engraftment respiratory distress syndrome, diffuse alveolar hemorrhage, drug-induced lung injury, immune checkpoint inhibitor-related pneumonitis, and radiation pneumonitis, while late or chronic complications, such as organizing pneumonia, interstitial lung disease, bronchiolitis obliterans syndrome, and chronic graft-versus-host disease-related lung involvement, typically develop months to years after therapy. Accurate and timely diagnosis is essential, relying on high-resolution CT, bronchoalveolar lavage, and, in selected cases, lung biopsy to differentiate these conditions from infections. Current treatments remain largely empirical, focusing on corticosteroids, supportive intensive care, and immunosuppressive adjustment, although novel strategies, including inhaled hemostatic agents and JAK inhibitors, are emerging. Despite advances in supportive management, late-onset complications remain associated with poor long-term functional outcomes. Future directions include the development of biomarkers, artificial intelligence-assisted radiological tools, and multicenter registries to improve classification, risk stratification, and treatment. In this narrative review, we highlight current evidence around noninfectious pulmonary complications in the critical care setting, diagnosis, and treatment.<\/jats:p>","DOI":"10.1055\/a-2707-2920","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T22:56:31Z","timestamp":1760741791000},"page":"163-173","source":"Crossref","is-referenced-by-count":0,"title":["Noninfectious Severe Pulmonary Complications in Immunocompromised Critically Ill Patients"],"prefix":"10.1055","volume":"47","author":[{"given":"Silvia","family":"De Rosa","sequence":"additional","affiliation":[{"name":"Centre for Medical Sciences, University of Trento, Trento, Italy"},{"name":"Anesthesia and Intensive Care, Santa Chiara Hospital, Azienda Provinciale per i Servizi Sanitari di Trento, Trento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Lassola","sequence":"additional","affiliation":[{"name":"Anesthesia and Intensive Care, Santa Chiara Hospital, Azienda Provinciale per i Servizi Sanitari di Trento, Trento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Gualdi","sequence":"additional","affiliation":[{"name":"Anesthesia and Intensive Care, IRCCS Ospedale Policlinico San Martino, Genoa, Italy"},{"name":"Department of Surgical Sciences and Integrated Diagnostics, University of Genoa, Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise","family":"Battaglini","sequence":"additional","affiliation":[{"name":"Anesthesia and Intensive Care, IRCCS Ospedale Policlinico San Martino, Genoa, Italy"},{"name":"Department of Surgical Sciences and Integrated Diagnostics, University of Genoa, Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,10,17]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"89","DOI":"10.37201\/req\/s01.20.2022","article-title":"Etiology, diagnosis, and management of pneumonia in immunosuppressed patients","volume":"35","author":"M Salavert Llet\u00ed","year":"2022","journal-title":"Rev Esp Quimioter"},{"issue":"01","key":"ref2","doi-asserted-by":"crossref","first-page":"xiii","DOI":"10.1016\/j.ccm.2024.12.001","article-title":"Challenges of managing pulmonary disease in the immunocompromised host","volume":"46","author":"G S Cheng","year":"2025","journal-title":"Clin Chest Med"},{"issue":"02","key":"ref3","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1038\/sj.bmt.1703784","article-title":"Engraftment syndrome after autologous hematopoietic stem cell transplant supported by granulocyte-colony-stimulating factor (G-CSF) versus granulocyte-macrophage colony-stimulating factor (GM-CSF)","volume":"31","author":"M Akasheh","year":"2003","journal-title":"Bone Marrow Transplant"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1067\/j.cpradiol.2018.07.006","article-title":"Imaging of pneumonias and other thoracic complications after hematopoietic stem cell transplantation","volume":"48","author":"G S Shroff","year":"2019","journal-title":"Curr Probl Diagn Radiol"},{"issue":"01","key":"ref5","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1186\/s12931-021-01699-8","article-title":"Lung transplantation for late-onset non-infectious chronic pulmonary complications of allogenic hematopoietic stem cell transplant","volume":"22","author":"P Riddell","year":"2021","journal-title":"Respir Res"},{"issue":"01","key":"ref6","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1016\/j.bbmt.2018.07.036","article-title":"Whole-body lung function test-derived outcome predictors in allogenic stem cell transplantation","volume":"25","author":"S Scheidl","year":"2019","journal-title":"Biol Blood Marrow Transplant"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"102055","DOI":"10.1016\/j.trim.2024.102055","article-title":"Nuances in the interpretation and utility of donor-derived cell-free DNA in lung transplantation following allogeneic hematopoietic stem cell transplantation -
