Insights
Thyroid status and metabolic issues impact oxygenation during pregnancy. This study highlights the importance of specific Doppler ratios like the Cerebroplacental ratio (CP) for predicting outcomes in preterm delivery cases.
Area of Science:
- Obstetrics and Gynecology
- Endocrinology
- Fetal Medicine
Background:
- Thyroid gland status and metabolic disturbances are crucial for maintaining adequate oxygenation, especially during pregnancy.
- Predictive parameters for fetal well-being are essential in managing high-risk pregnancies.
Purpose of the Study:
- To investigate the role of thyroid analysis and metabolic indices in women experiencing preterm delivery.
- To evaluate the utility of Doppler sonography, including the Cerebroplacental ratio (CP), in assessing fetal well-being in cases of preterm delivery.
Main Methods:
- A cross-sectional study of 99 women with preterm delivery, including thyroid analysis, Oral Glucose Tolerance Test (OGTT), and Homeostatic Model Assessment for Insulin Response (HOMA IR) indices.
- Doppler sonography of the umbilical artery and measurement of the Cerebroplacental ratio (CP) were performed.
Main Results:
- Women undergoing Cesarean section for preterm delivery showed significantly higher pulsatility index and Cerebroplacental ratio (CP) values compared to those with vaginal delivery.
- Maternal age averaged 32.23 years, and gestational age was 35.40 weeks.
Conclusions:
- Doppler sonography, particularly the CP ratio, aids in the clinical assessment of patients with preterm delivery.
- Thyroid antibodies and gestational diabetes can contribute to oxidative stress, impacting pregnancy outcomes.
Objectives:
Ad fontes, the status of the thyroid gland, and metabolic disturbance lead to the alteration of oxygenation. In pregnancy, it is particularly crucial to possess all predictive parameters.
Methods:
This cross-sectional study was conducted at the Clinic of Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade, Serbia, between 2017 and 2021 which study included a total of 99 women who had been admitted for preterm delivery and had undergone thyroid analysis, detected Hashimoto thyroiditis, and Oral Glucose Tolerance Test (OGTT) 40 days after delivery and had pathological Homeostatic Model Assessment for Insulin Response (HOMA IR) indices. In the group of urgent patients with preterm delivery, we looked after not only routine Doppler of the umbilical artery, but we measured specific ratios such as the Cerebroplacental ratio (CP).
Results:
The mean maternal age was 32.23 ± 5.96 years and the mean gestational age was detected as 35.40 ± 2.39 weeks. The delivery was completed vaginally in 77 women (78%) and surgically in 22 (22%). The Mean APGAR score was 8.44 ± 1.18, the mean birth weight was 2666.87 ± 622.17g and the cases undergoing cesarean section had significantly higher values of pulsatility index (1.85 ± 0.27 vs. 1.34 ± 0.31) and CP (1.22 ± 0.26 vs. 0.47 ± 0.17).
Conclusions:
The introduction of Doppler sonography for blood flow assessment helps to form a complete clinical description of the patient, particularly in conditions where oxidative stress became provocative by the thyroid gland antibodies and gestational diabetes in Thyroidology.
