ABSTRACT
Objective To evaluate the diagnostic utilities of CD64,CDllb,sICAM-1 and sE-selectin in early identification of neonatal sepsis related to bacterial infection. Methods The group of sepsis consisted of 36 newboms and the control group included 26 healthy newboms. The blood samples were collected right after being admitted to hospital and at recovery stage in the group of sepsis,as for the control the blood samples were collected only once in the study. In the sepsis group,blood samples were also taken in bacterial culture before treatment CD64 and CDllb were quantified with direct immunofluorescence staining and the whole blood cell flow cytometry analysis. sICAM-1 and sE-selectin level were determined by ELJSA assay,along with CRP. Results The expression level of CD64 in neonates with sepsis was (60. 37 22. 70) .shown in MFI,which was significantly higher than that in the group of control (23. 14 ±5. 10) MFI(P <0. 01). The expression level of CDllb in neonates with sepsis was (1645. 14 ±463. 68) MFI,which was significantly higher than that in the group of control (1041.48 ±260. 34) MFI (P < 0. 01). The concentration of blood sICAM-1 in neonates with sepsis was (240. 20 ± 83.46) μg/L, which was significantly higher than that in the group of control (100. 24 ±51.03)μg/L(P <0. 01). The concentration of blood sE-selectin in neonates with sepsis was (29. 63 ±9. 88μg/L,which was significantly higher than that in the group of control (14. 12 ±5. 33)μg/L(P <0. 01). In the sepsis group,the level of CD64,CDllb,sICAM-l and sE-selectin in the primary stage was higher than the recovery stage significantly (P <0. 01). The sensitivity of above-mentioned molecular markers were 95. 7% , 82. 6% , 81. 8% and 87. 0% , respectively, and the specificity were 95. 8% , 79. 2% ,86.9% and 79.2% . CD64 was the best one. Conclusions CD64 may serve as one of the reliable biomarkers in the early diagnosis of neonatal sepsis, and it may play important role in the treatment of neonatal sepsis.
