TOPLINE:
A study comparing cervical pessary and vaginal progesterone for the prevention of preterm birth in women with a short cervix of ≤ 35 mm found no significant difference between the interventions for perinatal complications. Among women with a cervical length of ≤ 25 mm, however, pessaries appeared to be less effective at preventing spontaneous preterm birth and adverse outcomes, according to the researchers.
METHODOLOGY:
- Researchers conducted an open-label, randomized controlled trial at 20 hospitals and five obstetric ultrasound practices in the Netherlands.
- The study included 635 women with healthy singleton pregnancies between 18 and 22 weeks’ gestation and an asymptomatic short cervix of ≤ 35 mm. Participants had no history of spontaneous preterm birth.
- Women were randomly assigned to receive either an Arabin cervical pessary or 200 mg/d vaginal progesterone for ≤ 36 weeks of gestation.
- The investigators examined a composite measure of adverse perinatal outcomes, including (grade, > 1), chronic lung disease, (grade, III or IV), (stage, > 1), , stillbirth, and death of the baby.
TAKEAWAY:
- Adverse perinatal outcomes occurred in 6% of each treatment group, and the rate of spontaneous preterm birth did not differ significantly between the groups.
- In a subgroup analysis of 131 patients with a cervical length of ≤ 25 mm, spontaneous preterm birth at < 28 weeks occurred more often in the pessary group (16% vs 4%).
- Adverse perinatal outcomes also seemed to occur more frequently in the pessary group (24% vs 12%; relative risk, 2.1 [95% CI, 0.95-4.60]), in the subgroup analysis, according to the researchers.
IN PRACTICE:
“Even though the study was not powered for the subgroup with a short cervix of ≤ 25 mm, results suggest that a cervical pessary should not be used as preventive treatment in this group,” the researchers wrote.
SOURCE:
The study was led by Charlotte E. van Dijk, MD, with Amsterdam UMC, University of Amsterdam, Amsterdam, the Netherlands. It was published online in The BMJ.
LIMITATIONS:
The researchers were unable to mask the treatment groups, which could introduce bias. The study’s reliance on self-reported medication adherence in the progesterone group and a lack of extra training for pessary placement might have influenced the outcomes, the researchers noted.
DISCLOSURES:
The study was supported by Stichting Stoptevroegbevallen, a nonprofit research foundation. An author disclosed financial ties with Merck.
