OBJECTIVES: After return of spontaneous circulation, patients who experienced out-of-hospital cardiac arrest present an impaired innate immune response that resembles sepsis. Presepsin, a new biomarker for sepsis, has not been studied in out-of-hospital cardiac arrest patients. This study explored the role of presepsin in evaluating the prognosis and early innate immune alteration of out-of-hospital cardiac arrest patients after return of spontaneous circulation by observing presepsin levels, CD14, and human leukocyte antigen-DR expression on monocytes.
DESIGN: Retrospective analysis.
SETTING: The emergency department of an urban university tertiary hospital.
PARTICIPANTS: One hundred sixty-five out-of-hospital cardiac arrest patients with return of spontaneous circulation more than 12 hours, and 100 healthy individuals.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Plasma presepsin and procalcitonin levels were tested after resuscitation (day 0) and on days 1 and 3 after return of spontaneous circulation. Presepsin levels were higher in out-of-hospital cardiac arrest patients than in healthy individuals. In the first 3 days, presepsin and procalcitonin levels were persistently lower in 28-day survivors and patients with favorable neurologic outcome patients than in 28-day nonsurvivors and patients with unfavorable neurologic outcome. On days 0, 1, and 3, different cut-off values of presepsin showed prognostic value for 28-day mortality and favorable neurologic outcomes similar to procalcitonin. CD14 and human leukocyte antigen-DR expression on monocytes were analyzed by flow cytometry. Compared with controls, CD14 expression in out-of-hospital cardiac arrest patients increased on day 1 and began to decrease on day 3, whereas human leukocyte antigen-DR+ monocyte percentages decreased on days 1 and 3. Presepsin and procalcitonin had a low positive correlation with CD14 expression and a strong negative correlation with human leukocyte antigen-DR+ monocyte percentages on day 1.
CONCLUSIONS: Plasma presepsin concentrations are independent prognostic factors for out-of-hospital cardiac arrest patients after return of spontaneous circulation and are correlated with abnormal CD14 and human leukocyte antigen-DR expression on monocytes. Monitoring presepsin levels may be helpful for evaluating the prognosis and impaired innate immune response in the early period after return of spontaneous circulation.
