Background: The pathogenic role of concomitant pulmonary cytomegalovirus (CMV) infection on morbidity and mortality of Pneumocystis pneumonia (PCP) has been questioned in non-HIV-infected patients with PCP.

Methods: We compared retrospectively demographics, clinical characteristics, morbidity, and mortality between the groups of PCP with (n = 31) and without (n = 75) pulmonary CMV infection in non-HIV-infected patients. Morbidity of PCP was assessed by length of hospital stay, admission to intensive care unit, and use of mechanical ventilation. Mortality of PCP was defined as 30-day and 90-day all-cause mortality. Cox proportional hazard model was performed to determine covariates associated with 90-day all-cause mortality after PCP. 

Results: The morbidity and mortality of PCP were not significantly different between PCP patients with and without CMV infection, regardless of initial severity of PCP. There was a trend toward an increased 90-day all-cause mortality in PCP patients without CMV (42.7%) compared to those with CMV (22.6%; P = .051). In multivariate analysis using Cox proportional hazard model, solid organ transplant recipient (RR, 0.17; 95% CI, 0.05–0.56; P = .004) and use of mechanical ventilation (RR, 6.49; 95% CI, 2.84–14.83; P < .001) were independently associated with 90-day all-cause mortality. However, concomitant pulmonary CMV infection was not associated with mortality of PCP.

Conclusion: Our result suggests that concomitant pulmonary CMV infection do not significantly increase the severity of PCP, as indicated by morbidity and mortality, in non-HIV-infected patients with PCP.
