Summary

The purpose of this study is to investigate the expression of protein biomarkers in cervical vaginal fluid in women with preterm premature rupture of membranes (PPROM)

Detailed description

Preterm premature rupture of the membranes (PPROM) prior to 37 weeks of gestation occurs in approximately 3% of all pregnancies and is associated with one-third of all preterm births (Mercer, 2003). While there are multiple possible etiologies of PPROM, intra-amniotic infection has been implicated as a major contributor, especially at early gestational ages where fetal and neonatal adverse sequelae are frequent (Yoon, et al. 2000). Micro-organisms are recovered from the amniotic fluid obtained by trans-abdominal amniocentesis in 25-40% of women at the time of presentation with PPROM (Simhan and Canavan 2005). Significant risks to the fetus following PPROM include both complications related to prematurity and to infection or inflammation (ACOG Practice Bulletin 2007). Complications related to prematurity include respiratory distress, intraventricular hemorrhage, and necrotizing enterocolitis. IAI, both clinically apparent and occult, is an important and potentially preventable cause of cerebral white matter injury and cerebral palsy. Ideally, an early diagnosis of IAI in the setting of PPROM is important to allow timely treatment and intervention. Amniocentesis is successful from 40 - 72% of the time with PPROM (Garite, 1982, Blackwell and Berry, 1999). Despite the accuracy for determining infection and the feasibility of amniocentesis, the vast majority of clinicians are reluctant and/or unwilling to perform this procedure in this clinical setting (Capeless and Mead, (1987). There is therefore a critical need for a noninvasive test to identify patients with IAI and PPROM. Timely identification of these sub-clinically infected patients is critical in designing rationale and efficacious treatment strategies that may reduce the fetal and neonatal sequelae associated with PPROM.
