META.ANALYSIS 0F C.REACTE PRoTEIN AND
PRoCALCIToNIN IN EARLY DIAGNOSIS OF
NEONATAL
SEPTICEMIA
ABSTRACT
Obj ective:To
systematic review the accuracy
of C-reactive protein
and procalcitonin in early diagnosis of neonatal septicemia.
Methods:Cochrane systematic
evaluation was used to search through
PubMed,Cochrane Library,CMCC,CNKI
for studies regarding CRP and
PCT in
the diagnosi s of neonatal
septicemia.Data were extracted and
analyzed
using software
MetaDisc
1.4
Results:In total,9 relevant studies were searched.The threshold
effects was
not
found.However,heterogeneity was found by other
reasons
Pooled accuracy indicator like sensitivity,specificity of CRP and PCT in
the study were 0.818
VS
0.859,0.755
VS
0.916,respectively.The area under
summary receiver operating characteristics
curve
were 0.8814
VS
0.9523;
and
Q
index were O.81 19
vs
O.8936 for CRP
and PCT,respectively
Conclusions:With
the
high
sensitivity,CRP and
PCT both
are
important indicators in the diagnosis of neonatal septicemia.Combined
determination of CRP and PCT Can increase the accuracy ofdiagnosis
Key word:CRP,PCT,neonatal septicemia,meta-analysis

C反应蛋白与降钙素原对新生儿败血症早期诊断价值
的系统评价
前言
新生儿败血症(neonatal septicemia)是指病原体侵入新生儿血液循环,并在其
体内生长、繁殖、产生毒素并发生全身炎症反应综合征。根据临床症状出现的时
间,可将新生儿败血症分为早发型新生儿败血症(72小时内)及晚发型新生儿败
血症(72小时之后)Il J,这种分型有助于鉴别引起新生儿败血症的病原菌。早发
型新生儿败血症常见于婴儿出生时被母亲产道病原菌感染【21,常见病原菌为链球
菌、大肠杆菌等【3】。而晚发型新生儿败血症一般由医院或者社区等体外环境中的病
