Objective To compare the significance of IL-6 and C reactive protein (CRP) in early diagnosis and prognosis of neonatal sepsis,and to timely detect neonates in high-risk of infection. Methods A total of 80 neonatal sepsis patients from January 2009 to December 2012 in NICU who met the criteria were included,and 80 cases of non-sepsis were set as the control group.After admission,blood was collected before use of antibiotics,and then submitted for CRP,IL-6 detection,blood routine examination and blood culture.The CRP and IL-6 were reviewed at 4 h,24 h after the use of antibiotics for patient in the case group and control group. Results 1) There were significant differences (P<0.05) between the sepsis group and the control group for the IL-6 and CRP.After 4 h of the antibiotics usage,IL-6 increased significantly to a peak;whereas CRP peaked at 24 h after the antibiotics usage.2) In premature and full-term neonates group,the diagnosis sensitivity and specificity of IL-6 were significantly higher than CRP after 4 h of the antibiotics usage. Conclusions IL-6 has a high sensitivity and specificity for the early diagnosis of neonatal sepsis.IL-6 monitoring at 4 h after infection is most sensitive,and CRP is most sensitive at 24 h after infection.Abnormally high levels of IL-6 increased early than CRP.
