PJP severity was assessed by the requirement for intensive care unit (ICU) admission.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>The median age of the 249 patients was 63 [IQR: 53\u201373] years. The main conditions were haematological malignancies (44.2%), solid organ transplantations (16.5%), and solid organ cancers (8.8%). Overall, 36.5% patients were admitted to ICU. CMV was detected in BAL in 57\/227 patients; the 37 patients with viral load \u22653 log copies\/mL were more frequently admitted to ICU (78.4% vs 28.4%, p&lt;0.001). CMV was also detected in blood in 57\/194 patients; the 48 patients with viral load \u22653 log copies\/mL were more frequently admitted to ICU (68.7% vs 29.4%, p&lt;0.001). ICU admission rate was found to increase with each log of BAL CMV viral load and each log of blood CMV viral load.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>PJP is more severe in the case of concomitant CMV detection.
