This retrospective study evaluated the prognostic value of bronchoalveolar lavage fluid (BALF) CMV DNA loads in 189 AIDS patients with pulmonary infections and CD4+ T cell counts &lt; 200 cells\/\u03bcL. CMV DNA in BALF and plasma was quantified to analyze associations with immune status and 90-day all-cause mortality. CMV detection was significantly more frequent in BALF (49.7%) than plasma (26.6%), indicating viral compartmentalization. An optimal BALF cutoff of 10,000 copies\/mL was established for mortality prediction. Patients exceeding this threshold exhibited significantly lower CD4+ counts, increased mechanical ventilation requirements (34.4% vs. 11.5%), and prolonged hospital stays. Crucially, a BALF CMV load &gt; 10,000 copies\/mL was identified as an independent predictor of 90-day mortality (adjusted odds ratio = 3.78; 95% CI: 1.12\u201312.71). In conclusion, pulmonary CMV replication is prevalent and often compartmentalized in AIDS patients. A BALF CMV DNA load exceeding 10,000 copies\/mL serves as a biomarker of profound immunosuppression and independently predicts poor clinical outcomes, highlighting the necessity of quantitative BALF monitoring for risk stratification.<\/jats:p>","DOI":"10.3390\/pathogens15040377","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T08:08:34Z","timestamp":1775030914000},"page":"377","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bronchoalveolar
