摘要

Abstract

Background

An accurate diagnosis of early onset sepsis (EOS) is challenging due to subtle symptoms and the lack of a good diagnostic tool, resulting in considerable antibiotic overtreatment. A biomarker, discriminating between infected and non-infected newborns early in the disease, could improve EOS prediction. Numerous biomarkers have been tested, but have never been compared directly.

Objective

We aimed to provide a comprehensive overview of early biomarkers and their diagnostic value in maternal samples, umbilical cord blood and neonatal serum.

Data Sources

PubMed-Medline, EMBASE, The Cochrane Library and Web of Science were searched until March 1st 2023, without restrictions in publication date, population, or language.

Study eligibility criteria

Articles describing the diagnostic value of at least one biomarker in the detection of EOS in neonates, independent of gestational age, were included.

Assessment of risk of bias

The QUADAS-2 tool was used to assess study quality.

Methods of data synthesis

Three independent researchers assessed articles using PRISMA guidelines. Meta-analysis was performed with all manuscripts describing diagnostic accuracy using a random-effects model.

Results

Of 2296 identified articles, 171 reports were included in the systematic review and 69 in the meta-analysis. Literature showed mixed and inconsistent evidence for most biomarkers and sample types, due to a lack of a uniform EOS case definition, small sample sizes and large heterogeneity between studies. Interesting markers were PCT (pooled sensitivity 79%, 95% CI, 71%-84%; specificity 91%, 95% CI, 83%-96%, n=11) and IL-6 (pooled sensitivity 83%, 95% CI, 71%-90%; specificity 87%, 95% CI, 78%-93%, n=8) in umbilical cord blood and presepsin (pooled sensitivity 82%, 95% CI, 62%-93%; specificity 86%, 95% CI, 73%-93%, n=3) and serum amyloid A (pooled sensitivity 92%, 95% CI, 75%-98%; specificity 96%, 95% CI, 78%-99%, n=4) in neonatal serum. Studies on the combination of biomarkers were scarce.

Discussion

A biomarker stand-alone test is currently not reliable to direct antibiotic stewardship in newborns, although several biomarkers show promising initial results. Further research into biomarker combinations could lead to an improved EOS diagnosis, reduce antibiotic overtreatment and prevent associated health related problems.
