Insights
Presepsin effectively identifies postoperative sepsis and septic shock after abdominal surgery. Monitoring presepsin levels aids in early detection, distinguishing sepsis from normal inflammation in surgical patients.
Area of Science:
- Critical Care Medicine
- Surgical Infections
- Biomarker Discovery
Background:
- Postoperative inflammatory responses complicate early sepsis detection.
- Presepsin, a biomarker, increases in sepsis patients.
- Identifying sepsis early after major abdominal surgery is challenging.
Purpose of the Study:
- Compare diagnostic abilities of presepsin and other biomarkers for postoperative sepsis and septic shock.
- Evaluate presepsin's utility in the acute postoperative period.
- Assess biomarkers for predicting sepsis and septic shock within 7 days post-surgery.
Main Methods:
- Prospective measurement of presepsin, procalcitonin, and white blood cell counts in 298 patients undergoing surgery for intra-abdominal infection.
- Serial measurements taken for 3 days post-ICU admission (T0-T3).
- Analysis of diagnostic values and significant risk factors for sepsis/septic shock.
Main Results:
- Sepsis and septic shock occurred in 91 and 38 patients, respectively.
- Presepsin and procalcitonin showed comparable diagnostic abilities for early sepsis prediction.
- Elevated presepsin and procalcitonin levels at specific time points were significant predictors of septic shock.
Conclusions:
- Presepsin demonstrates feasible diagnostic accuracy for sepsis and septic shock in the acute postoperative phase.
- Presepsin monitoring is valuable for differentiating new sepsis from normal inflammation post-surgery.
- The study highlights presepsin's role in managing patients after intra-abdominal infection surgery.
Introduction:
It is difficult to identify early sepsis after surgery due to postoperative inflammatory reactions. Presepsin, a glycoprotein expressed on the surface of innate immune cells, is produced during bacterial phagocytosis, and its level increases in the bloodstream of sepsis patients. We aimed to measure the differences between the diagnostic ability of presepsin and other biomarkers to identify postoperative sepsis and septic shock in acute period after major abdominal surgery.
Methods:
From March 2020 to March 2021, patients who underwent surgery due to intra-abdominal infection were enrolled. Level of presepsin and procalcitonin, and white blood cell counts were prospectively measured every morning for 3 d from intensive care unit admission after surgery (from T0 to T3). Diagnostic values of inflammatory markers were compared to predict early development of sepsis or septic shock within 7 d after surgery. Cut-off value of significant risk factor associated with postoperative sepsis or septic shock were evaluated.
Results:
Among 298 patients, postoperative sepsis and septic shock occurred in 91 and 38 patients, respectively. For prediction of early postoperative sepsis or septic shock, presepsin and procalcitonin had comparable diagnostic abilities. In multivariate analysis, presepsin > 406.5 pg/mL at T0 (Odds Ratio [OR]:4.055, P = 0.047), presepsin > 1216 pg/mL at T2 (OR:40.030, P = 0.005) and procalcitonin > 1.685 ng/mL at T2 (OR: 5.229, P = 0.008) were significant factors for predicting the occurrence of early postoperative septic shock.
Conclusions:
Diagnostic accuracy of presepsin for sepsis or septic shock was feasible in acute postoperative period. It would be useful to monitor newly developed sepsis from normal inflammatory response, especially in patients who underwent surgical operation for the elimination of intra-abdominal infection.
