Study Notes

Thyroid Hormone Synthesis

  • Thyroid Peroxidase (TPO) is an enzyme essential for thyroid hormone synthesis, catalyzing the oxidation of iodide and the iodination of tyrosine residues on thyroglobulin.
  • TPO helps form thyroid hormones triiodothyronine (T3) and thyroxine (T4) through the oxidation of iodide and the coupling of iodotyrosines.

Thyroid Disorders and Cholesterol Metabolism

  • Thyroid disorders can significantly impact cholesterol metabolism, with hypothyroidism often resulting in elevated low-density lipoprotein (LDL) cholesterol levels and hyperthyroidism leading to decreased LDL cholesterol levels.

Regulation of Thyroid Hormones by TSH

  • Thyroid-stimulating hormone (TSH) is produced by the anterior pituitary gland and plays a crucial role in regulating thyroid hormone production by stimulating the release of T3 and T4 from the thyroid gland.

Treatment Options for Hyperthyroidism

  • Treatment options for hyperthyroidism include antithyroid medications (e.g., methimazole), radioactive iodine therapy, and surgical removal of part or all of the thyroid gland (thyroidectomy).

Importance of Newborn Screening for Thyroid Disease

  • Screening for thyroid disease in newborns is crucial, as congenital hypothyroidism can lead to cretinism if left untreated, while early treatment can prevent intellectual disability and developmental delays.
