Summary
Predicting preterm birth (PTD) is challenging due to multiple causes. Recent methods using cervical length and biochemical markers show promise for early detection and risk assessment.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Biology
- Biochemistry
Background:
- Preterm birth (PTD) is a leading cause of neonatal morbidity and mortality.
- PTD arises from complex interactions of four primary pathogenic mechanisms: HPA axis activation, inflammation, decidual hemorrhage, and myometrial distention.
- Traditional prediction methods based on obstetrical history and risk factors lack sensitivity and specificity.
Purpose of the Study:
- To review the pathogenic mechanisms of PTD.
- To evaluate current and emerging methods for predicting PTD risk.
- To highlight the potential of multi-biomarker approaches for improved prediction.
Main Methods:
- Review of clinical and experimental evidence on PTD pathogenesis.
- Analysis of traditional and recent predictive methods for PTD.
- Discussion of biochemical and biophysical pathways involved in PTD.
Main Results:
- PTD involves a common final pathway of myometrial activation and protease activity, despite diverse initiating mechanisms.
- Sonographic cervical length measurement and biochemical markers (hCG, cytokines, fFN, MMPs, estrogens, CRH) offer improved PTD prediction sensitivity.
- Current prediction methods are insufficient, necessitating advanced approaches.
Conclusions:
- Understanding the heterogeneous etiopathogenesis of PTD is crucial for effective prediction.
- Multi-biomarker strategies are essential to increase sensitivity and specificity in PTD risk assessment.
- Future research should focus on integrating multiple markers to identify individual contributions to PTD risk.
