Maternal thyroid dysfunction and neonatal thyroid problems.

Area of Science:

• Endocrinology
• Obstetrics
• Neonatology

Background:

• Thyroid dysfunction during pregnancy can impact both maternal and infant health.
• Autoimmune thyroid disease is a common endocrine disorder in pregnant women.
• Neonatal thyroid screening is crucial for early detection of thyroid dysfunction.

Purpose of the Study:

• To examine obstetric complications in pregnant women with thyroid disorders.
• To evaluate thyroid function in newborns of mothers with thyroid conditions.
• To compare outcomes among women with autoimmune hypothyroidism, non-autoimmune hypothyroidism, and healthy controls.

Main Methods:

• Categorization of pregnant women into three groups: autoimmune hypothyroidism (Group I), hypothyroidism without autoantibodies (Group II), and controls (Group III).
• Assessment of obstetric features and maternal thyroid function tests.
• Evaluation of neonatal thyroid function tests, including thyroid-stimulating hormone (TSH) and free thyroxine (FT4).

Main Results:

• Group I (autoimmune hypothyroidism) experienced higher rates of preterm delivery and neonatal intensive care unit (NICU) admissions.
• Infants in Group I showed instances of compensated hypothyroidism and transient hyperthyrotropinemia.
• Elevated TSH levels were observed in a significant percentage of infants in Group II (23.8%) and Group III (6.5%) at specific postnatal time points.

Conclusions:

• Infants born to mothers with thyroid disorders have a higher likelihood of elevated TSH levels and increased recall rates in neonatal screening.
• Close monitoring of women with thyroid disorders and their newborns is essential for managing obstetric complications and potential thyroid dysfunction.
• Early detection and management of maternal and neonatal thyroid dysfunction are critical for optimal outcomes.
