A cohort study with four groups of pregnant women was designed to evaluate if a decrease in the concentration of fibronectin (FN) in amniotic fluid plays a role in the genesis of premature rupture of the membranes (PROM) and/or intra-amniotic infection: group 1, 15 patients with PROM and intra-amniotic infection; group 2, 15 patients with PROM but without intra-amniotic infection; group 3, 15 patients with preterm labor without PROM or intra-amniotic infection; and group 4, 15 patients who underwent elective amniocentesis for fetal lung maturity studies. No significant differences in amniotic fluid concentrations of FN among any of the four groups was observed (F = 0.146; P = 0.931). These results suggest that a deficiency of FN in amniotic fluid is not a critical factor in determining which patients may be affected by PROM or which of them will develop an intra-amniotic infection.

UI MeSH Term Description Entries
D007752 Obstetric Labor, Premature Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D011251 Pregnancy Complications, Infectious The co-occurrence of pregnancy and an INFECTION. The infection may precede or follow FERTILIZATION.

D005322 Fetal Membranes, Premature Rupture Spontaneous tearing of the membranes surrounding the FETUS any time before the onset of OBSTETRIC LABOR. Preterm PROM is membrane rupture before 37 weeks of GESTATION.

D005353 Fibronectins Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.

D000649 Amniocentesis Percutaneous transabdominal puncture of the uterus during pregnancy to obtain amniotic fluid. It is commonly used for fetal karyotype determination in order to diagnose abnormal fetal conditions. Amniocenteses
D000653 Amniotic Fluid A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).
