Preterm
birth occurring before the thirty-seventh gestational week complicates 4.5%-18%
of pregnancies worldwide. The pathogenesis of spontaneous preterm delivery is
not fully understood. Among the factors held to be responsible for its
pathogenesis, the most emphasized is the inflammatory process. Studies in terms
of the prediction of preterm delivery are basically divided into 3 categories:
1) Prediction in pregnant women who are asymptomatic and without risk factors,
2) Prediction in pregnant women who are asymptomatic and have risk factors, 3)
Prediction in symptomatic pregnant women who have threatened preterm labour. In
this chapter, the topic of biomarkers in relation to preterm delivery is
discussed. The most commonly used markers in published studies are fetal
fibronectin, cervical pIGFBP-1 and cervical length measurement by transvaginal
ultrasound. For prediction in symptomatic pregnant women applying to the
hospital with threatened preterm labour, the markers used are fetal
fibronection, insulin-like growth factors (IGFs) and inflammatory markers.
Preterm labour prediction with markers checked in the first and second trimesters
are fetal fibronection, insulin-like growth factors (IGFs), micro RNAs, progesterone,
circulating microparticles (CMPs), inflammatory markers, matrix metalloproteinases,
aneuploidy syndrome screening test parameters and other hormones.
