Abstract:
Objective:To investigate the diagnostic value of neutrophil CD64 index in sepsis patients in intensive care unit (ICU).Methods:A prospective case-control study was conducted, the patients admitted to ICU of Jiangbei People's Hospital Affiliated to Nantong University from December 2016 to June 2020 were enrolled. According to the criteria of Sepsis 3, 107 patients diagnosed with sepsis were classified as the sepsis group, 112 patients without infection were classified as control group. Peripheral venous blood samples were collected within 24 hours after ICU admission, neutrophil CD64 index, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC) were detected. Receiver operating characteristic curve (ROC curve) was used to evaluate the diagnostic value of neutrophil CD64 index, CRP, PCT and WBC for sepsis.Results:The neutrophil CD64 index, CRP and PCT in sepsis group were significantly higher than those in control group [neutrophil CD64 index: 9.03±5.59 vs. 3.18±1.50, CRP (mg/L): 146.9±68.3 vs. 46.5±35.8, PCT (ng/L): 31.82±14.71 vs. 1.87±1.42, all P < 0.05]. ROC curve analysis showed that neutrophil CD64 index, CRP and PCT had certain diagnostic value for sepsis, the area under ROC curve (AUC) were 0.924, 0.915 and 0.879, respectively, the 95% confidence intervals (95% CI) were 0.871-0.978, 0.855-0.975, 0.807-0.951, respectively, P values were 0.016, 0.017 and 0.026, respectively. Among the three indicators, the diagnostic value of neutrophil CD64 index was much higher. When the optimal cut-off value was 4.32, the sensitivity and specificity were 83.6% and 88.7%, respectively, which were higher than the sensitivity (75.1%, 76.3%) and specificity (87.2%, 82.5%) of CRP and PCT. Conclusion:Neutrophil CD64 index is a valuable biomarker for the diagnosis of sepsis in ICU.
