Pessary Plus Progesterone to Prevent Preterm Delivery in Women with Short Cervical Length

Rodolfo de Carvalho Pacagnella from the Universidade Estadual de Campinas in Brazil will perform two randomized clinical trials across 15 obstetric clinics in Brazil to evaluate treatment with progesterone in the presence or absence of a cervical pessary for preventing spontaneous preterm birth. Both cervical pessary and progesterone are individually considered to be effective preventative treatments for preterm birth, which is one of the most common complications seen in pregnancy and can cause severe complications for the premature infant. The causes of preterm birth are mostly unknown, although incidence does increase with cervical shortening during the mid stages of pregnancy. They will also analyze the prevalence of a short cervix in Brazilian pregnant women, and determine how well it predicts preterm birth. Their approach to screen for cervix length and then treat high-risk individuals with the combination therapy will also be evaluated for cost-effectiveness.
