Pregnancy Complications in Women with Polycystic Ovary Syndrome (PCOS)
Increased Risk of Pregnancy Complications in PCOS
Women with polycystic ovary syndrome (PCOS) face a significantly higher risk of various pregnancy complications compared to those without the condition. These complications include early pregnancy loss (EPL), gestational diabetes mellitus (GDM), pregnancy-induced hypertension (PIH), preeclampsia, and preterm birth . The increased risk of EPL in women with PCOS is often linked to factors such as obesity, hyperinsulinemia, elevated luteinizing hormone levels, and endometrial dysfunction.
Gestational Diabetes and Hypertensive Disorders
Gestational diabetes is notably more prevalent in pregnant women with PCOS, with studies indicating a 3-4 fold increase in risk . Similarly, the risk of pregnancy-induced hypertension and preeclampsia is significantly higher, with odds ratios ranging from 2.17 to 3.67 . These conditions are exacerbated by common PCOS features such as hyperandrogenism, obesity, and insulin resistance .
Preterm Birth and Neonatal Outcomes
Preterm birth is another concern, with women with PCOS showing a 1.75 to 1.93 times higher risk compared to controls . Additionally, their babies are more likely to be admitted to neonatal intensive care units (NICU) and face higher perinatal mortality rates . Impaired insulin-mediated growth and fetal programming are potential explanations for these adverse neonatal outcomes.
Role of Metformin in Managing PCOS During Pregnancy
Metformin, a common treatment for insulin resistance in PCOS, has shown promise in reducing the risk of late miscarriage and preterm birth. However, its administration throughout pregnancy remains a contentious issue. Metformin's immunomodulatory effects, rather than anti-inflammatory properties, have been observed, with significant impacts on cytokine levels in pregnant women with PCOS. This suggests that metformin may help manage some of the immunological challenges associated with PCOS during pregnancy.
Impact of Thyroid Function
Thyroid dysfunction is more prevalent among women with PCOS, which can further complicate pregnancy outcomes. Studies have shown that PCOS women and their neonates have higher levels of thyreoperoxidase antibodies (TPO-AB), indicating a higher prevalence of autoimmune thyroiditis. This thyroid dysfunction can contribute to the overall risk profile for pregnancy complications in PCOS.
Long-term Health of Offspring
The long-term health of children born to mothers with PCOS is also a concern. Elevated androgen levels in daughters of PCOS mothers may indicate earlier maturation and an increased risk of developing PCOS themselves. Additionally, metformin exposure in utero may impact steroidogenesis in children, although more research is needed to confirm these findings.
Conclusion
Women with PCOS are at a higher risk for several pregnancy complications, including gestational diabetes, hypertensive disorders, and preterm birth. Metformin shows potential in managing some of these risks, but its use throughout pregnancy remains debated. Thyroid dysfunction and long-term health impacts on offspring are additional concerns that require further research. Comprehensive care and monitoring are essential for managing pregnancies in women with PCOS to mitigate these risks.
