Open Access Abstract Background The present study sought to investigate the correlation of copeptin with the severity of septic status in patients with ventilator-associated pneumonia VAP and to analyze the usefulness of copeptin as a predictor of mortality in VAP. Methods The prospective observational cohort study was conducted in a teaching hospital. The subjects were 71 patients consecutively admitted to the intensive care unit from October 2003 to August 2005 who developed VAP. Copeptin levels were determined on day 0 and day 4 of VAP. Patients were followed for 28 days after the diagnosis when they were considered survivors. Patients who died before day 28 were classified as nonsurvivors. There were no interventions. Results Copeptin levels increased from sepsis to severe .
