Screening for preeclampsia in twin pregnancies

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatology

Background:

• Twin pregnancies significantly increase the risk of preeclampsia, a serious hypertensive disorder.
• Preeclampsia in twins poses substantial risks to both maternal and perinatal health.
• Early identification of high-risk pregnancies is vital for implementing preventive measures and close monitoring.

Purpose of the Study:

• To review existing literature on the prediction and prevention of preeclampsia specifically in twin pregnancies.
• To identify established risk factors and assess the performance of current screening models in this population.
• To evaluate the evidence regarding the efficacy of interventions like low-dose aspirin for preeclampsia prevention in twins.

Main Methods:

• Comprehensive literature search of studies focusing on preeclampsia in twin pregnancies.
• Analysis of risk factors, prediction models, and prevention strategies.
• Review of clinical trial data and observational studies on aspirin intervention.

Main Results:

• Risk factors for preeclampsia in twin pregnancies are less defined compared to singleton gestations.
• Current screening models for preeclampsia in twins demonstrate suboptimal performance with high false-positive rates.
• The benefit of low-dose aspirin for preventing preeclampsia in twin pregnancies remains unclear and requires further investigation.

Conclusions:

• There is a critical need for improved prediction models for preeclampsia in twin pregnancies.
• Further research is essential to establish effective preventive strategies, including optimal use of aspirin.
• Enhanced understanding and management are required to reduce maternal and perinatal morbidity associated with preeclampsia in twins.
