%X OBJECTIVE: This meta-analysis aimed to comprehensively assess the teratogenic risk to offspring associated with continuing pregnancy after administering mifepristone and/or misoprostol during gestation.
METHODS: We conducted a systematic search of multiple databases, including PubMed, Web of Science, Embase, Cochrane, CNKI, and CBM, from their inception to February 2024, with no language restrictions. We included cohort and case-control studies that analyzed the teratogenic effects of mifepristone and/or misoprostol on fetuses and newborns. Quality assessment was performed using the Newcastle-Ottawa Scale (NOS). The odds ratios (OR) from individual studies were combined using meta-analysis. Sensitivity testing and heterogeneity analysis were conducted.
RESULTS: A total of 13 studies were eligible for inclusion, comprising 5193 cases of congenital malformations and 12,232 controls.
CONCLUSIONS: Our findings indicated that the use of misoprostol during early pregnancy increased the risk of congenital abnormalities in offspring (OR = 2.69; 95% CI: 1.57-4.62). However, the potential teratogenic effect of mifepristone during pregnancy cannot be ruled out. Additionally, the use of mifepristone and/or misoprostol has been linked to a higher risk of certain congenital anomalies, such as hydrocephalus (OR = 3.41; 95% CI: 1.17-9.97), Möbius syndrome (OR = 26.48; 95% CI: 11.30-62.01), and terminal transverse limb defects (OR = 10.75; 95% CI: 3.93-29.41).
