The Value of sTREM-1, PCT, and CRP as Markers for the Detection of Sepsis and Bacteremia Among Patients With a FUO
The investigators enrolled 144 subjects admitted to ICUs: 60 patients with systemic inflammatory response syndrome (SIRS) and 84 patients with sepsis. Tests for serum sTREM-1, PCT, and CRP levels and blood culture were performed on the day of admission and with the occurrence of FUO (>38.3ºC) during hospitalization. Based on the results of blood culture, the subjects were divided into bacteremia (33 patients) and non-bacteremia groups (51 patients). Based on 28-day survival, bacteremia patients were also divided into survivor (22 patients) and non-survivor groups (11 patients). Serum sTREM-1 and PCT levels were summarized as medians (interquartile ranges) and CRP levels were presented as means ± standard deviations. To explore the early diagnostic value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1), procalcitonin (PCT), and C-reactive protein (CRP) serum levels for identification of sepsis and bacteremia and the prognosis among patients with a fever of unknown origin (FUO) in the intensive care unit (ICU) and to discuss the clinical application of the results.

systemic inflammatory response syndrome
(1) temperature > 38oC or < 36oC; (2) pulse rate > 90 beats/min; (3) ventilation rate > 20 breaths/min or hyperventilation with a partial pressure of arterial carbon dioxide (PaCO2) < 32 mmHg; (4) white blood cell (WBC) count >1 2,000μL-1 or < 4000 μL-1 , or > 10% immature cells.
SIRS + infection
(1) The blood culture tested positive at least for the same pathogen;(2) The patient had at least one of the following symptoms: fever, shivering, or low blood pressure and showed signs of at least one of the following conditions: the blood culture tested positive at least twice for common skin flora from different sites; the blood culture tested positive only once for the skin flora listed above, the intravascular catheter culture tested positive for the same pathogen and the correct antibiotic treatment had been initiated for the patient; or a positive serology test consistent with other clinical laboratory test results and unrelated to infections at different sites.
