Background: Pneumocystis jirovecii pneumonia (PJP) is a life-threatening disease. In the intensive care unit (ICU), PJP is most frequently observed among patients with several conditions not related to the human immunodeficiency virus (HIV) infection. Methods: The primary objective of the present post-hoc analysis of a multicenter, multinational, retrospective study was to assess factors impacting prognosis in ICU patients with PJP through univariable and multivariable analyses. Results: A total of 107 patients were included; 28 had proven PJP (26.2%), and 79 had presumptive PJP (73.8%). The overall 30-day mortality was 52.7% (95% confidence interval [CI] 42.1–62.2). In the multivariable analysis, metastatic solid tumor (hazard ratio [HR] 3.49; 95% CI 1.71–7.13, p < 0.001) and chronic liver disease (HR 2.44; 95% CI 1.03–5.80, p = 0.044) showed an independent association with 30-day mortality. The direction of effect remained consistent when center was added to the multivariable model as random effect. Conclusion: PJP mortality remains high in ICU patients. Conditions other than HIV infection are emerging not only as non-classical risk factors for PJP development, but also as important mortality predictors. A better understanding of the reasons underlying this evolving landscape could be crucial to improve PJP management and survival. © 2025 The Author(s).

Abstract
Background: Pneumocystis jirovecii pneumonia (PJP) is a life-threatening disease. In the intensive care unit (ICU), PJP is most frequently observed among patients with several conditions not related to the human immunodeficiency virus (HIV) infection. Methods: The primary objective of the present post-hoc analysis of a multicenter, multinational, retrospective study was to assess factors impacting prognosis in ICU patients with PJP through univariable and multivariable analyses. Results: A total of 107 patients were included; 28 had proven PJP (26.2%), and 79 had presumptive PJP (73.8%). The overall 30-day mortality was 52.7% (95% confidence interval [CI] 42.1–62.2). In the multivariable analysis, metastatic solid tumor (hazard ratio [HR] 3.49; 95% CI 1.71–7.13, p < 0.001) and chronic liver disease (HR 2.44; 95% CI 1.03–5.80, p = 0.044) showed an independent association with 30-day mortality. The direction of effect remained consistent when center was added to the multivariable model as random effect. Conclusion: PJP mortality remains high in ICU patients. Conditions other than HIV infection are emerging not only as non-classical risk factors for PJP development, but also as important mortality predictors. A better understanding of the reasons underlying this evolving landscape could be crucial to improve PJP management and survival. © 2025 The Author(s).
