[SCD14-ST (presepsin) level monitoring in cardiac surgical patients during perioperative period].

Unlabelled: Purpose of the study was to define prognostic ability of presepsin (sCD14-ST) as a predictor of complications in cardiac surgical patients during perioperative period.

Methods: Patients operated for acquired heart valvular diseases with cardiopulmonary bypass were involved in the study (n = 51, age 58 +/- 11 years). Following parameters were studied; demographic data, duration of cardiopulmonary bypass, time of aorta clamping, severity-of-disease by APACHE II scale before surgery, on 1st, 2nd, 3rd and 6th day after surgery, routine clinical laboratory data and sCD14-ST.

Results: there were no clinical laboratory evidences of inflammation before surgery in all patients. There was no difference between biomarkers in patients who had normal condition during postoperative period and in patients who had complications and/or untoward outcomes during postoperative period. Presepsin level in 6 patients (11.8%) was 543 (519-602) ng/ml, maximal 1597 ng/ml. Infection complications accrued in 19 patients (37%). Hospital mortality was 13.7% (7 patients), all cases of death was in group of patients with infection complications. Statistically significant differences in the level of presepsin and severity-of-disease by APACHE II in groups of patients with infection complications and without accrued on 1st and 2nd days of postoperative period. Optimal split point were 702 ng/ml, 8.5 points and 3.3 ng/ml. Increased postoperative level of presepsin is associated with a risk of infection complications and untoward outcomes.

Conclusion: sCD14-ST monitoring with the use of severity-of-disease scales and recent biomarkers allow to identify patients with high risk of infection complications and untoward outcomes.
