Folate antagonists during early pregnancy augment heart disease risk; folic acid helps, emphasizing careful medication use for healthier pregnancies.
Published in the prestigious British Journal of Clinical Pharmacology, the outcomes of a systematic review and meta-analysis unveiled a concerning association between maternal exposure to folate antagonists and amplified susceptibility to congenital heart diseases in the child.
Prajjwol Luitel and colleagues aimed at assessing the impact of folate antagonist administration on congenital heart disease rates, embarked on a comprehensive journey through medical literature. By scouring databases like MEDLINE, PubMed and EMBASE, the team gathered insights from a multitude of studies extending from 1976 to 2020.
The analysis of 6 cohort studies and 5 cross-sectional studies found that maternal exposure to folate antagonists within the 12 weeks before conception and during the second and third months of pregnancy suggestively elevates the risk of congenital heart diseases in babies. The odds ratio stood at 1.55, with a confidence interval of 95%, indicating a notable increase in vulnerability.
Adding on, the protective effects of folic acid supplementation were observed in cases linked to dihydrofolate reductase inhibitors, the same wasn't observed for those associated with antiepileptic drugs. This variation underlines the intricacies of prenatal care and the need for customized procedures.
