Abstract :

Prophylactic treatment with synthetic 17-hydroxyprogesterone caproate (17OHPC) or natural progesterone (P) prevents preterm birth (PTB) in women with a previous PTB and in asymptomatic women with a short cervical length (CL) at midpregnancy. Since only 10% of spontaneous PTB occur in women with a previous PTB and less than 2% of asymptomatic women have a CL <25 mm at midpregnancy, the criteria for initiating prophylactic treatment remains uncertain. Only a few studies have investigated the effect of therapeutic P treatment after the onset of preterm labour (PTL). The aim of this study was to investigate whether additional P treatment could prolong the latency to delivery in women after the onset of PTL. Women with a singleton pregnancy, PTL between 24 - 34 weeks, intact fetal membranes and a CL <25 mm were randomized to additional treatment with daily doses of P in vaginal gel (n=19) or a placebo gel (n=18) after intravenous tocolysis. Forty four women with identical inclusion criteria treated with intravenous tocolysis served as controls. The latency to delivery was increased by 7 weeks in the P group and by 6 weeks in the placebo group. The latency to delivery in the control group was 4 days (p<0.00001 vs. P and placebo). In conclusion, additional treatment with P significantly increased the latency to delivery in women with extreme and early PTL as compared to intravenous tocolysis alone. A treatment with a placebo gel increased latency in a manner comparable to P.
