Brief Summary:
This protocol outlines a randomized trial of 630 women evaluating the use of micronized vaginal progesterone or pessary versus control (placebo) to prevent early preterm birth in women carrying twins and with a cervical length of less than 30 millimeters.
Detailed Description:
This protocol outlines a randomized trial of 630 women evaluating the use of micronized vaginal progesterone or pessary versus control (placebo) to prevent early preterm birth in women carrying twins and with a cervical length of less than 30 millimeters.
Multiple gestation increases the risk of preterm delivery. Babies born preterm have increased rates of neonatal mortality and long-term neurodevelopmental morbidities. Short cervical length is known to be an important risk factor for spontaneous preterm birth and to occur more frequently in women with a twin gestation. Although there is no evidence that progesterone reduces the risk of preterm birth in multifetal gestation, there is evidence that progesterone reduces the risk of prematurity in singleton gestations complicated with a short cervix. The Arabin pessary has also been shown to reduce the risk of preterm birth among singletons with a short cervix, and in a secondary subgroup analysis of a recent study of the use of pessary in multiple gestations, women with a cervical length \< 25th percentile had a significantly reduced risk of the primary composite neonatal adverse outcome. Secondary analysis of studies of vaginal progesterone in multiple gestation with a short cervix also suggest a possible beneficial effect on preterm delivery.
