Abstract

OBJECTIVE:

To investigate procalcitonin (PCT) change pattern in patients with septic shock and its relationship with prognosis.

METHODS:

Sixty-three septic shock patients were enrolled, and levels of PCT, C-reactive protein (CRP) as well as white blood cell (WBC) on 1st, 3rd, 5th,7th day after admission to intensive care unit (ICU) were checked. Patients were divided into survival group and death group according to 28-day survival result. Differences in parameters between two groups were compared. The change regulation of parameters along with in-hospital period and its relationship with prognosis were analyzed by multilevel linear model.

RESULTS:

There were 41 patients in survival group and 22 patients in death group. PCT and CRP level decreased in survival group with time dependency pattern, while death group increased. The PCT at 3, 5, 7 days after admission to ICU in death group were significantly higher than those in survivors (3 days: 8.7±3.7 μg/L vs. 5.6±1.7 μg/L, 5 days: 10.3±1.3 μg/L vs. 4.8±2.3 μg/L, 7 days: 12.7±2.3 μg/L vs. 0.8±0.3 μg/L, P<0.05 or P<0.01), and CRP at 5 days and 7 days was significantly higher than those in survival group (5 days: 447±63 mg/L vs. 355±91 mg/L, 7 days: 439±45 mg/L vs. 364±63 mg/L, both P<0.05). Two groups of WBC did not change significantly, and there were no statistical significance difference at each time point between the two groups. What's more, the effect analysis results showed that there were significant changes in PCT as ICU day prolonged (F=10.91, P= 0.00), and there was a significant difference between the survivor and the dead (F=7.58, P=0.00), while CRP changed only with ICU stays (F=4.17, P=0.03).

CONCLUSIONS:

Compared with CRP and WBC, PCT had higher sensitivity in predicting prognosis, sustainable elevation of PCT level indicates poor prognosis, serum PCT can be used as one of indexes predicting prognosis of septic shock.
