Introduction: The role and incidence of viral infections in respiratory failure occurring in ICU patients is more and more investigated. The availability of multiplex PCR assay is actually frequently performed. The aim of this retrospective study was to assess presence of viral species using a multiplex PCR assay in adult patients admitted to ICU for respiratory failure during the November—April period.
Patients and methods: All adult patients admitted to ICU during the November—April period for respiratory failure were eligible. A respiratory sampling was performed according to patient severity—sputum, tracheal aspiration, or per fibroscopic broncho alveolar lavage LBA and was analyzed for conventional bacterial strain.
Forty-nine patients required invasive mechanical ventilation. Co infection by bacteria and virus was noted in 4 patients. Influenzae virus was found in 10 patients and VRS in nine. Four patients with a positive viral sample had a fatal outcome Influenza virus was found in all these. Conclusion: Positive viral sample is not infrequent in ICU patients with respiratory failure. VRS is in this study as frequently found than influenzae.
Introduction: Plasma citrulline concentration, a biomarker of enterocyte function, is frequently low among critically ill patients. Plasma citrulline concentration might be decreased among critically ill patients presenting with sepsis, reflecting an alteration of small bowel function.
We aimed to study the link between plasma citrulline concentration measured at ICU admission and variables related to the sepsis in critically ill patients. Patients and methods: This was a prospective observationnal study performed in a University Hospital. Plasma citrulline concentration, plasma I-FABP biomarker of enterocyte damage , search for sepsis, results of bacterial sample, and usual clinical and biological variables were collected.
