[Sepsis biomarkers dynamics as an indicator of intensive care effectiveness]

To evaluate dynamics of presepsin, procalcitonin and C-reactive protein in survived and dead patients with sepsis.

There were 41 patients with diagnosis of 'sepsis' ('Sepsis-3' concept) who were divided into 2 groups: survived patients with sepsis (21 people) - group 1, dead patients with sepsis (20 people) - group 2. All patients underwent generally accepted intensive therapy for sepsis. Besides conventional laboratory and instrumental examination, dynamics of presepsin, procalcitonin and C-reactive protein was assessed.

Mean level of presepsin was 1718.00 and 3266.50 pg/ml in groups 1 and group 2, respectively. Half of the values was within (Me (25; 75) 1021.00-3231.00 pg/ml and 1618.50-7469.00 pg/ml in both groups, respectively. Mean level of procalcitonin was 0.995 and 4.465 ng/ml, respectively. Median (25; 75) was 0.49-4.44 ng/ml and 1,625-19.30 ng/ml, respectively. Mean level of C-reactive protein was 95.5 and 215.0 mg/L, respectively, median (25; 75) - 64.00-155.00 mg/L and 155.00-264.00 mg/L, respectively. Significant differences were determined for all variables (p-value 0.000008, 0.000242, 0.0000001 for presepsin, procalcitonin and C-reactive protein, respectively).

The levels of C-reactive protein, procalcitonin and presepsin were significantly different in patients with sepsis followed by favorable and unfavorable clinical outcome. Unfavorable outcome was associated with increased levels of all biomarkers. Comprehensive assessment of all biological markers of sepsis is useful to assess an effectiveness of intensive therapy and to predict clinical outcome.
