Prevention of preterm birth with combined vaginal progesterone & cervical cerclage

Combined treatment of cervical cerclage and vaginal progesterone achieves a greater reduction in preterm birth than in single therapy.

PUBLICATIONS

  • A systematic review and meta-analysis studied if combined therapy offers superior effectiveness vs. single therapy in prevention of preterm birth.

  • High-risk, singleton, pregnant patients (shortened cervical length <25mm or previous preterm birth) were assigned cervical cerclage, vaginal progesterone, or both for prevention of preterm birth.

  • Primary outcome: birth <37 weeks and secondary outcomes: birth <28 weeks, <32 weeks and <34 weeks, gestational age at delivery, days between intervention and delivery, PPROM, cesarean delivery, neonatal mortality, NICU admission, intubation, and birthweight were assessed.

  • Combined therapy was associated with lower risk of preterm birth at <37 weeks than cerclage alone or progesterone alone.

  • Compared with cerclage only, combined therapy was associated with preterm birth at <34 weeks, <32 weeks, or <28 weeks, decreased neonatal mortality, increased birthweight, increased gestational age, and a longer interval between intervention and delivery.

  • Compared with progesterone alone, combined therapy was associated with preterm birth at <32 weeks, <28 weeks, decreased neonatal mortality, increased birthweight, and increased gestational age.

  • There were no differences in any other secondary outcomes.
