Since pathologies and complications occurring during pregnancy and/or during labour may cause adverse outcomes for both
newborns and mothers, there is a growing interest in metabolomic applications on pregnancy investigation. In fact,
metabolomics has proved to be an efficient strategy for the description of several perinatal conditions. In particular, this study
focuses on premature rupture of membranes (PROM) in pregnancy at term. For this project, urine samples were collected at
three different clinical conditions: out of labour before PROM occurrence (Ph1), out of labour with PROM (Ph2), and during
labour with PROM (Ph3). GC-MS analysis, followed by univariate and multivariate statistical analysis, was able to discriminate
among the different classes, highlighting the metabolites most involved in the discrimination.
1. Introduction
The early diagnosis of pregnancy-related complications and
the prediction of pregnancy outcome are considered strategic
clinical goals to ensure the health of mothers and of their
babies. Among these, premature rupture of membranes
(PROM) consists of the rupture of the foetal membranes
before the onset of labour. It can be observed at any gesta-
tional age [1] and occurs in approximately 10% of pregnant
women and in roughly 40% of preterm deliveries [2]. Foetal
membranes are of pivotal importance because they offer a
robust barrier against infection ascending from the repro-
ductive tract; after their rupture, both the mother and foetus
are at risk of infection and other complications. The most
commonly diagnosed maternal infections in case of PROM
are chorioamnionitis and endometritis, which may be further
promoted by frequent vaginal exams and the presence of
meconium in the amniotic fluid (AF) [3]. Foetal complica-
tions of PROM include neonatal sepsis, abnormal foetal pre-
sentation, cord prolapse or compression, and abruptio
placentae, and these may increase the risk of neonatal intra-
ventricular haemorrhage, leading to neurodevelopmental
disability as a direct consequence [4]. Therefore, from
PROM, diagnosis may derive different medical procedures
such as hospitalization, antibiotic prophylaxis, and induction
of labour through oxytocin [5, 6], that is, increased medical-
ization and caesarean section rates. These practices may in
turn affect several women in the positive experience of birth
[7]. Moreover, given the increasing antibiotic resistance,
alerts have been issued about the use and abuse of prophylac-
tic antibiotic administration [8]. Indeed, growing evidences
on this phenomenon suggest possible short- and long-term
