Index pregnancy versus post-index pregnancy in patients with recurrent pregnancy loss Academic Article uri icon


  • Abstract Objective: To compare pregnancy outcomes of two consecutive pregnancies in a cohort of women with recurrent pregnancy loss (RPL), in order to determine the long-term prognosis of women with RPL managed in a dedicated RPL clinic. Methods: A retrospective cohort study including 262 patients with two or more consecutive pregnancy losses followed by two subsequent pregnancies - Index pregnancy (IP) and post-Index pregnancy (PIP). All patients were evaluated and treated in the RPL clinic in the Soroka University Medical Center.Results: Comparing IP with PIP, no significant difference in perinatal outcome was observed. The perinatal outcome remained encouraging with approximately 73% birth rate (73.7% vs. 72.5%; p=0.83). Only 11% of the women with RPL continued to experience pregnancy losses for two subsequent pregnancies. In a multivariate logistic regression analysis, number of miscarriages pre-Index was the only factor independently associated with birth in the PIP.Conclusion: There is no significant difference between IP and PIP regarding perinatal outcome. Appropriate management in the RPL clinic conferred a significant beneficial effect on long-term pregnancy outcome of a cohort of women with RPL.
