Summary of "Vaginal progesterone after tocolytic therapy in threatened preterm labor."

Abstract Objective: The aim of this study was retrospective evaluation of progesterone efficacy in pregnant patients with preterm uterine contractions. Methods: 190 women hospitalized at 1st Department of Obstetrics and Gynecology, Medical University of Warsaw, in 2007-2010, with symptoms of threatened preterm labor were enrolled in the study. 94 women were treated with tocolytics and steroids (control group), while 96 women received additionally 200 mg of progesterone vaginally until delivery or 34th weeks of gestation (progesterone group). Results: The mean gestational age at admission was 27 weeks in progesterone group and 28 weeks in control group. Cervical length was similar in both groups. There were no significant differences in week of delivery between groups, but the progesterone group had significant increase in prolongation of pregnancy (7.6 versus 6.3 weeks, p=0.039). Vaginal progesterone was associated with reduction of delivery before 34 weeks (9.8% versus 35.3%; p=0.002) and neonatal birth weight < 1500g (3.2% versus 20.6%; p=0.011) only in patients presenting with uterine contractions after 27 weeks. Conclusions: The administration of vaginal progesterone after tocolysis in threatened preterm labor is associated with prolongation of pregnancy. The reduction of deliveries before 34 weeks was observed in patients presenting with contractions after 27 weeks gestation.

The Effects of Progesterone Therapy on the Gestation Length and Reduction of Neonatal Complications in Patients who had Received Tocolytic Therapy for Acute Phase of Preterm Labor.

While tocolytic therapy can halt the process of delivery, some patients return before the 37th week of pregnancy with recurrence of preterm labor signs.

The role of cervical length in women with threatened preterm labor - is it a valid predictor at any gestational age?

To determine whether the predictive accuracy of sonographic cervical length for preterm delivery (PTD) in women with threatened preterm labor (PTL) is related to gestational age (GA) at presentation.

Background: Vaginal bleeding is a common complication during pregnancy, which is observed in about 1/4 of pregnancies and in half of cases can lead to abortion. If vaginal bleeding happens during preg...

Low levels of circulating T-regulatory lymphocytes and short cervical length are associated with preterm labor.

Recent discoveries suggest that T-regulatory lymphocytes (Treg) might play an important role in the pathophysiology of preterm labor. The aim of this study was to assess the relationship among the lev...

Medical and Biotech [MESH] Definitions

Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete.

Allowing a woman to be in LABOR, OBSTETRIC long enough to determine if vaginal birth may be anticipated.

UTERINE BLEEDING from a GESTATION of less than 20 weeks without any CERVICAL DILATATION. It is characterized by vaginal bleeding, lower back discomfort, or midline pelvic cramping and a risk factor for MISCARRIAGE.

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.

Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.
