Abstract:
Objective To demonstrate the influence of PCT concentration and its descent to the prognosis of patients with hospital acquired bacterial pneumonia. Methods The PCT concentration was determined. One hundred and thirteen HAP patients were enrolled from September 2011 and November 2012 , including 64 patients in the non-survival group and 49 patients in the survival group , and 92 non-infected patients in the control group. The relationship between PCT and hospital days and survival rate was analyzed. Results The initial value of PCT in the non-survival group and in the survival group were higher than that in the control group, while the PCT in the non-survival group was the highest, with significant difference (P =0.0002). Taking PCT = 0.78 μg/L as the cut-off value, the sensitivity and specificity to predict the mortality of the HAP patients was 0.66 and 70%, respectively. A significant negative correlation was shown between PCT value and hospital days in the non-survival group. The survival rate of patients with PCT decrease over 50% was higher than that of patients with PCT decrease less than 50% after treatment. Conclusion Dynamic monitoring PCT in patients with bacterial HAP possesses a certain significance.
