Abstract

Background: The incidence of Clostridioides difficile infection (CDI) in peripartum women is rising, but limited data on its effect on maternal and neonatal outcomes are available.

Objective: To study the effect of peripartum CDI on pregnancy and neonatal outcomes.

Design: Retrospective cohort study.

Methods: Patients with peripartum CDI 12 weeks before pregnancy through 6 weeks postpartum (January 1996-February 2018) were matched with controls (peripartum women without CDI) 1:1 by age, year of delivery, and prior pregnancies. McNemar's test and conditional logistic regression were used to analyze the effect of CDI on pregnancy and neonatal outcomes (complications, mode of delivery). p < 0.05 was considered statistically significant.

Results: Overall, 101 cases and 100 controls (1997-2018) were included; median age 27 (range, 20-41) years. Timing of CDI was as follows: pre-pregnancy: 15.8% (n = 16), during pregnancy: 51.5% (n = 52), and postpartum: 32.7% (n = 33). The commonest risk factor was outpatient/emergency room visits. Pregnancy and neonatal outcomes were analyzed for 67 matched pairs with CDI before or during pregnancy. Cases had higher odds of cesarean delivery (p = 0.02) and lower odds of Group B Streptococcus (GBS) infection/colonization (p = 0.03). Odds of cesarean delivery remained high after controlling for labor arrest disorders [odds ratio (OR): 17.23 (95% confidence interval (CI), 2.19-543.19; p = 0.004)]; odds of GBS remained low after controlling for antibiotic use (OR: 0.25, 95% CI, 0.04-0.99; p = 0.049). Neonatal outcomes were similar in cases and controls. CDI treatment did not affect treatment-related or delivery outcomes.

Conclusion: Peripartum CDI was associated with higher odds of cesarean delivery and lower odds of GBS infections. Larger studies exploring the effect of CDI on pregnancy and neonatal outcomes are needed.
