Investigating Cytomegalovirus Reactivation in ICU Patients on Mechanical Ventilation

Cytomegalovirus Reactivation in Non-immunosuppressed Patients Requiring Prolong Mechanical Ventilation

Sanjay Gandhi Postgraduate Institute of Medical Sciences · NCT06520605

This study looks at whether critically ill patients on breathing machines get a virus called Cytomegalovirus (CMV) more often and how it might affect their recovery and survival.

What this trial studies

This observational study examines the reactivation of Cytomegalovirus (CMV) in critically ill patients requiring prolonged mechanical ventilation. It focuses on understanding how sepsis and its immunomodulatory effects may trigger CMV reactivation in patients who are otherwise considered immunocompetent. The study aims to document the incidence of CMV reactivation and its association with increased ICU stay and mortality rates. By analyzing the immune responses and viral loads in these patients, the research seeks to provide insights into the implications of CMV reactivation during critical illness.

Who should consider this trial

Good fit: Ideal candidates for this study are adult ICU patients requiring mechanical ventilation for at least 7 days and who are seropositive for CMV.

Not a fit: Patients under 18 years, those with known immune deficiencies, or those who have received antiviral treatment within the last week may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for critically ill patients, potentially reducing ICU stay and mortality associated with CMV reactivation.

How similar studies have performed: Previous studies have indicated a significant association between CMV reactivation and adverse outcomes in critically ill patients, suggesting that this approach has been explored with some success.
