[Comparative analysis of premature labor markers]

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Reproductive Biology

Background:

• Premature rupture of membranes (PROM) and preterm labor are significant concerns in pregnancy.
• Accurate diagnostic markers are crucial for timely intervention and improved outcomes.
• Existing diagnostic tools have limitations in predicting these conditions.

Purpose of the Study:

• To compare the diagnostic accuracy of fetal fibronectin (fFN), the Birth test (phosphorylated insulin-like growth factor binding-1), and the PROM test (insulin-like growth factor binding-1).
• To evaluate their utility in predicting premature rupture of membranes (PROM) and preterm labor with intact membranes.
• To determine the optimal use of each test based on patient population characteristics.

Main Methods:

• Comparative diagnostic study involving 167 pregnant women.
• Inclusion of three groups: asymptomatic women (n=120), confirmed PROM (n=21), and suspected PROM (n=26).
• Assessment of fFN, Birth test, and PROM test in predicting PROM and preterm labor.

Main Results:

• The predictive value of each test varied depending on the population characteristics.
• fFN and Birth test demonstrated high predictive value in pregnant women without PROM.
• The PROM test was optimal for pregnant women with suspected or confirmed PROM, irrespective of risk factors or contractile activity.

Conclusions:

• The choice of diagnostic marker for PROM and preterm labor prediction should be tailored to the specific clinical context and patient group.
• fFN and Birth test are valuable for risk assessment in asymptomatic pregnant women.
• PROM test offers optimal diagnostic utility in cases of suspected or confirmed PROM.
