Up. The duration of ICU stay and the ICU mortality rate were significantly higher in patients developing an active CMV infection than in patients from the control group (Table 4). However, there was no difference between the CMV group and the HSV group regarding these parameters. There was no correlation between the viral load and the number of ventilator-free days at D28 and D60 (data not shown).Impact of CMV and HSV on Ventilated PatientsFigure 3. Meta-analyse of the mortality associated with Herpes Simplex Virus (HSV) Diagnosis methods are detailed in table 6. doi:10.1371/journal.pone.0051340.gComplications such as bacteremia, acute renal failure or shock were significantly more frequent in the CMV group (Table 4). In contrast, there were no increases in the rate of inhibitor bacterial VAP or ARDS following virus identification in the CMV group when compared to the other two groups.DiscussionThe present study suggests that an active CMV infection in critically ill patients increases both crude and adjusted mortalities at day 60. CMV infection was also associated with less ventilator free days at day 28 and day 60, and an increased duration of ICUTable 5.
