Recurrence of premature rupture of membranes among pregnancies admitted to a Tertiary Hospital: a retrospective cohort study

Purpose The recurrence of PPROM (Preterm Premature Rupture of Membranes) has multifactorial etiology. The aim of this study is to discuss outcome measures of subsequent PPROMs after pregnancy with PPROM before 37 weeks 'gestation. Method One hundred fifty-one patients were identified with PPROM between 20 (+ 0)- 36 (+ 6) weeks of gestation between 2012 and 2017 in Trakya University Hospital. The subsequent pregnancy (n = 68) outcomes were retrospectively analyzed. Results The rate of PPROMs among all deliveries was 4.7%. The recurrence rate of PPROM in the next pregnancies was 13.2%. No differences in smoking, comorbidity, latency, antibiotic use, levels of leucocytes and C-Reactive Protein were observed between women with PPROM and without PPROM in previous and subsequent pregnancies. The interpregnancy intervals in subsequent pregnancies with PPROM were significantly longer than those without PPROM (p = 0.015). The subsequent pregnancies without PPROM had longer gestational weeks of PPROM and birth according to previous pregnancies (p = 0.049; p = 0.014). Conclusion The short interpregnancy interval may be considered in the planning of pregnancies of these women who had previous PPROM.
