Predicting EONS in PPROM Patients

Prediction of Early-Onset Neonatal Sepsis (EONS) in Pregnant Women With Preterm Premature Rupture of Membranes (PPROM) by Vaginal Microbiome Analysis - a Pilot Study

An EONS occurred in nearly 14-22 % of the preterm infant of pregnant women with PPROM. To this day no risk prediction is established. The main aim of this pilot study is generating primary data with a focus on the vaginal microbiome to set-up a prospective, multi-centre trial investigating the role of the vaginal microbiome for future EONS risk prediction.

The planned PEONS pilot trial is subdivided in three Work packages:

1. Recruitment, sample collection and routine clinical diagnostics
2. Microbiome analysis by 16S rRNA
3. Microbiome/ Metagenome analysis by "Nanopore" (proof-of-principle) and will enroll women with a PPROM event hospitalized between 22+0 and 34+0 weeks of gestation and neonates with signs of EONS (Subgroup 1) and without signs of EONS (Subgroup 2).

Inclusion Criteria:

• full age pregnant woman with PPROM and their born preterm infants
• hospitalization between 22+0 and 34+0 weeks of gestation
• multipara possible

Exclusion Criteria:

• hospitalization with PPROM before limit of viability are reached
• intrauterine fetal death
• no study agreement
• not able to consent
