hCG levels are essential for the correct interpretation of gestational TSH levels: the clinical risk assessment of premature delivery

Context: High maternal TSH and/or low FT4 during pregnancy is associated with an increased risk of premature delivery. hCG is the main determinant of thyroid function changes during pregnancy but has a versatile pattern with high inter and intra-individual variability. We hypothesised that the correct interpretation of thyroid function tests and its use in the risk assessment of premature delivery during pregnancy depend on hCG levels.Design, ...

Introduction: Adequate thyroid hormone availability during early life is crucial for normal child growth and development. Fetal growth in utero heavily depends on angiogenesis. Placental growth factor (PlGF) is a proangiogenic factor sharing high homology with vascular endothelial growth factor (VEGF) whereas soluble FMS-like tyrosine kinase-1 (sFlt1) is a potent antagonist of VEGF and PlGF signaling. Since the thyroid is a highly vascularized organ, we hypothesized t...
