Abstract: Objective To investigate the significance of peripheral blood CD64 index and white blood cell (WBC )for the early diagnosis and prognosis monitoring of sepsis in children. Methods A total of 57 children with sepsis, 65 children with pneumonia and 36 healthy children were enrolled. The index of CD64 was determined by flow cytometry, and WBC was determined by haematology analyzer. Results The index of CD64 and WBC in sepsis, pneumonia and healthy control groups had statistical significance (P<0.01). The index of CD64 in the blood culture positive was significantly higher than that in the blood culture negative (P<0.05). According to the receiver operating characteristic(ROC)curve, when the cut-off value in the diagnosis of sepsis was 2.25, the sensitivity was 88%, and the specificity was 85%. After treatment, the index of CD64 decreased significantly (P<0.01), but not to be the normal level, and the difference was statistically significant compared with the healthy control group (P<0.01).  Conclusions The index of CD64 has the clinical significance for the early diagnosis and prognosis of sepsis in children.
