Monitoring of Women With Preterm Premature Rupture of Membranes (PPROM) Between 28 and 33 Weeks of Gestation With Repetitive Immunochromatographic Bedside Test to Detect Inflammatory Protein in Vaginal Secretions.

Prematurity represents 8% of birth and it is one of the leading causes of infant complications. The preterm premature rupture of membranes (PPROM) represents one-third of preterm birth and the rupture of membranes increase the risk of fetal exposition to infection which could lead to neurological sequels. Classic management of women with PPROM before 32SA is based on the extension of the pregnancy with the risk of adding complications like a secondary infection. Moreover, different studies have shown that fetal infection could be one of the most important risk factor for subsequent neurological complications. However, it is difficult to know if it is better to extend the pregnancy to gain in maturity or to arrest the pregnancy to avoid the risk of intrauterine infection. The research objective is to suggest a new strategy to manage women with PPROM. With this new strategy, the investigators seek to extend pregnancy as much as possible but the investigators would like to give birth before the intrauterine infection. The investigators suggest detecting protein associate with neurological complications of preterm child in the amniotic liquid found in the vagina of the mother. A positive test will lead to the delivery of the newborn before its infection. The hypothesis is that it is possible to study changes in the inflammatory status of patients who presented an PPROM from repeated detection of interleukins in vaginal secretions.
