Abstract
AIM A large cohort study of Japanese women reported that the rate of recurrent spontaneous preterm delivery (sPTD) in the next pregnancy was 22.3%; therefore, it is important to prevent recurrent sPTD. The present study investigated the rate of recurrent sPTD in pregnant women treated with probiotics. METHODS This was a retrospective study. Fifty-one pregnant women with a history of sPTD and who had been taking probiotics before 14 weeks of gestation were selected. The rate of sPTD in the next pregnancy among 255 pregnant women with a history of sPTD who had not taken probiotics was compared with that in the probiotics group. RESULTS The rate of recurrent sPTD was 9.8% (5/51), which was lower than previously reported values. Furthermore, the rate of recurrent sPTD was significantly lower in the probiotics group (9.8%) than in the nonprobiotics group (31.0% [79/255]; p = 0.002). CONCLUSIONS Probiotics may reduce the rate of recurrent sPTD.
