Cytomegalovirus (CMV) infection is common in immunocompetent patients in intensive care units (ICUs). However, whether CMV infection or CMV reactivation contributes to mortality of immunocompetent patients remains unclear. ⋯ Critically ill patients without immunosuppression admitted to ICUs show a high rate of CMV infection. CMV infection during the natural unaltered course or reactivation in critically ill patients is associated with increased mortality, but have no effect on mortality when CMV in blood. More studies are needed to clarify the impact of CMV infection on clinical outcomes in those patients.

Cytomegalovirus reactivation and mortality in patients with acute respiratory distress syndrome.
Cytomegalovirus (CMV) reactivation occurs frequently in patients with the acute respiratory distress syndrome (ARDS) and has been associated with increased mortality. However, it remains unknown whether this association represents an independent risk for poor outcome. We aimed to estimate the attributable effect of CMV reactivation on mortality in immunocompetent ARDS patients. ⋯ CMV reactivation is independently associated with increased case fatality in immunocompetent ARDS patients who are CMV seropositive.

Outcome of human immunodeficiency virus-exposed and -infected children admitted to a pediatric intensive care unit for respiratory failure.
Acute severe pneumonia with respiratory failure in human immunodeficiency virus-infected and -exposed infants carries a high mortality. Pneumocystis jiroveci is one cause, but other organisms have been suggested to play a role. Our objective is to describe the coinfections and treatment strategies in a cohort of human immunodeficiency virus-infected and -exposed infants with respiratory failure and acute respiratory distress syndrome, in an attempt to improve survival. ⋯ A case fatality rate of 30% is achievable if severe pneumonia with respiratory failure and acute respiratory distress syndrome is managed with a combination of antibiotics and ventilation strategies. Cytomegalovirus infection appears to be associated with an increased risk of death in this syndrome. This may, however, be a marker of as yet undefined pathology.

Viral infections in septic shock (VISS-trial)-crosslinks between inflammation and immunosuppression.
Recent investigations provided evidence that herpes simplex virus (HSV-1) and cytomegalovirus (CMV) are reactivated in critically ill individuals. However, at this time, it remains unclear whether these viral infections are of real pathogenetic relevance or represent innocent bystanders. ⋯ Viral superinfections with HSV-1 or CMV can frequently be observed in patients with septic shock, especially in those with increased disease severity and a prolonged need for respirator-dependant ventilation. In patients with a viral superinfection morbidity is increased, whereas differences in mortality seem to be dosage-dependant.
