PRO-MComplete for Determination of Rupture of Fetal Membranes

2015-03-11 02:08:22 | BioPortfolio

Summary

Premature rupture of membranes refers to the rupture of the fetal membranes prior to the onset of labor. Premature rupture of membranes is associated with a number of neonatal and maternal complications including an increased incidence of perinatal mortality and intra-amniotic infection. There is a need for improved diagnostic testing because of limitations of the current methods.

PRO-MComplete is an immunochromatographic test that detects insulin growth factor binding protein 1 and alpha-fetoprotein in vaginal fluid as an indicator of membrane rupture.

Description

Premature rupture of membranes (PROM) complicates approximately 8 % of pregnancies and is generally followed by the prompt onset of spontaneous labor and delivery. Preterm PROM complicates only 2 % of pregnancies but is associated with 40% of preterm deliveries and can result in significant neonatal morbidity and mortality (ACOG 2007). Intraamniotic infection has been shown to be commonly associated with preterm PROM, especially at earlier gestational ages (ACOG 2013). Currently, the diagnosis of PROM is based primarily on the patient's history and physical examination. The diagnosis of membrane rupture typically is confirmed by the visualization of amniotic fluid passing from the cervical canal and pooling in the vagina; a basic pH test of vaginal fluid; or arborization (ferning) of dried vaginal fluid, which is identified under microscopic evaluation (ACOG 2013).

The classic clinical presentation of PROM is a sudden "gush" of clear or pale yellow fluid from the vagina. However, many women describe intermittent or constant leaking of small amounts of fluid or just a sensation of wetness within the vagina or on the perineum (WHEC 2009).

However, the diagnosis of PROM is difficult if there is a slow fluid leak or any bleeding, or when the classic "gush of fluid "does not occur (Bornstein 2006).

Although ultrasonographically guided transabdominal instillation of indigo carmine dye and observation for fluid passage transvaginally is designated an "unequivocal" diagnostic method for confirmation of membrane rupture, this invasive test carries increased maternal and fetal risk (Mercer 2004). The absence of a non-invasive "gold standard" for the diagnosis of PROM has led to technically advanced biochemical markers for improved diagnosis (El-Messidi, 2010).

The AmniSure ROM (Rupture of Membranes) test received Food and Drug Administration 510(k) marketing clearance in 2003. A comparison study of AmniSure versus standard diagnostic methods for detection of ROM in 203 pregnant women suspected of ROM reported that the AmniSure test was highly accurate (sensitivity = 98.9 %, specificity = 100 %, and negative predictive value [NPV] = 99.1 %) in diagnosing ROM (Cousins et al, 2005). Test performance was calculated by comparing AmniSure results against clinical history, nitrazine and fern results, presence of pooling, ultrasound (US) evidence of oligohydramnios, and findings from repeated examinations.

Chen and Dudenhausen (2008) compared 2 rapid strip tests for the detection of amniotic fluid, based on the detection of insulin-like growth factor-binding protein-1 (IGFBP-1) and of PAMG-1. Samples of amniotic fluid were taken in 20 pregnant women between 31 3/7 and 41 2/7 gestational weeks at elective cesarean section before delivery of the newborn. These samples were diluted with 0.9 % saline solution in a dilution series down to concentrations of 1:320. Immunoassay strip tests were then compared in their ability to detect remaining concentrations of amniotic fluid. In 5 cases, both test methods showed the same results. In all remaining 15 cases, the test based on PAMG-1 proved to be superior by detecting amniotic fluid at least at one descending concentration below the test based on IGFBP-1.

PRO-MComplete proposes an alternative tool for adjuvant diagnosis of PROM by identification of Insulin-Like Growth Factor Binding Protein1 and Alpha Feto- Protein (AFP). The addition of AFP is projected to increase the sensitivity and specificity of PRO-MComplete over IGFBP-1 alone.
