Fetal fibronectin FFN. Biochemical markers of preterm birth

Abstract

The use of biochemical markers for predicting preterm birth has a potential advantage because it provides direct evidence of changes in the extracellular matrix of the surface between fetal membranes and decidual tissue.  [1, 12] fFN is a protein that is produced during pregnancy and acts as a biological glue such as the amniotic sac kept attached to the endometrium. fFN can be found in cervico-vaginal secretions up to 22 weeks and late in the last trimester. [7] The purpose of this study is to determine the level of fetal fibronectin (fFN) in cervical mucus as a specific indicator of preterm birth in pregnant women with clinical symptoms. The study was attended by 90 women divided into two groups. First group of pregnant women at term gestation 24-34 weeks with clinical symptoms the PB and the second group of pregnant women with normal pregnancy occurs. In all women was conducted Full Term Test. The results were statistically processed by using SPSS v. 17. The presence of symptoms of preterm labor showed difference in the percentage of positive results of fFN test (p <0.05), women with clinical symptoms have - a high percentage of positive tests. When conducting Full term pregnancy test with positive results in the highest percentage with overt clinical RTD, Roma and second and third birth. Furthermore, pregnant women with a positive test result mainly born at 35 weeks, newborns weighed an average of 2 550.1 g, which explicitly includes them in the premature population.
