Methods PCT was analyzed from blood samples of all patients at baseline and 155 patients 72 hours later. Results The median PCT serum concentration on day 0 was ng ml interquartile range IQR and ng ml and ng ml IQR and ng ml 72 hours later. Hospital mortality was 62 242 . Median PCT concentrations in patients with community-acquired infections were higher than with nosocomial infections P . Blood cultures were positive in of patients n 69 and severe sepsis with positive blood cultures was associated with higher PCT levels than with negative cultures P . Patients with septic shock had higher PCT concentrations than patients without P . PCT concentrations did not differ between hospital survivors and nonsurvivors P and P respectively but mortality was lower in patients whose PCT concentration decreased 50 by 72 hours compared to those with a 50 decrease vs. P . Conclusions PCT concentrations were higher in more severe forms of severe sepsis but a substantial concentration decrease was more important for survival than absolute values. Introduction Because promptly administered antimicrobial and early goal-directed treatment has been shown to improve outcome in patients with severe sepsis 1 2 early recognition of infection as a cause of critical illness is of major importance. Various biomarkers such as C-reactive protein CRP .
