Fibrates and risk of congenital malformations: a nationwide cohort study in South Korea

초록

Purpose To examine the association between maternal prescriptions for fibrates and congenital malformations in live births.Methods Nationwide retrospective cohort study was conducted using the data sourced from the Korean National Health Insurance database. A cohort of 756,877 completed pregnancies linked to live-born infants in 215,600 women with dyslipidemia between 2012 and 2021. The study compared data on congenital anomalies between pregnancies who were exposed to fibrates and those who were not exposed to fibrates in the first trimester. Odds ratios (OR) were calculated by a multivariable analyses using logistic regression models to adjust for potential confounders.Results 260 pregnancies (0.12%) were exposed to fibrates during the first trimester. The prevalence of malformations in exposed offspirng was 10.77%, not significantly different compared with 9.68% in offspring of women who were not prescribed fibrates during pregnancy in patients with dyslipidemia (OR 1.13; 95% CI 0.75-1.70).Conclusion This study implies that the use of fibrates during pregnancy may be safe, as it did not show any association with congenital anomalies. However, caution is warranted due to an elevated risk associated with prolonged exposure.
