Summary

Background: A preterm birth remain a worldwide important socioeconomic burden since prematurity has been consistently implicated in a wide range of health medical problems affecting newborn child and contributed in up to more than a half of overall perinatal mortality. Several studies have shown a significant therapeutic benefit as a result of an antenatal cervical pessary use in a high-risk preterm birth group of pregnant women. However the underlying mechanism by which pessary can reduce a risk of a preterm birth remain elusive. The study aims to quantitatively assess an ectocervical stiffness in a normal and in a treated with a pessary high-risk preterm birth pregnancy.

Methods: A prospective, non-interventional, post-market, monocentric, longitudinal, cohort study in a obstetric-led tertiary maternity teaching hospital to determine ectocervical stiffness and its changes measured prior and after the placement of a pessary, and the correlation of measured cervical stiffness or its changes with birth outcome in a high-risk preterm birth pregnant women indicated for cervical pessary. A cervical stiffness measured with Pregnolia system as the Cervical Stiffness Index (CSI, in mbar) will be a primary, whilst patient delivery data (gestational age, mode of delivery and complications) will be a secondary endpoint. In this pilot study, up to 142 subjects will be enrolled to have a total of 120 subjects (estimated dropout rate of 15%) completed the study; Pessary cohort: 60 (up to 71 recruited), normal cohort: 60 (up to 71 recruited).

Discussion: We hypothesize than the study will substantially improve our knowledge about cervical incontinency and preterm labour pathophysiology. We hope that our investigation will be able to elucidate ectocervical stiffness phenomenon both in high-risk preterm birth and in normal pregnant control, as well as the impact of cervical pessary use on a the CSI values.
