Treatment of Parathyroid hormone deficiency

# A deficiency of parathyroid hormone can be treated with:
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K

The correct answer is C. Vitamin D.

Hypoparathyroidism is a rare disorder associated with insufficient production of parathyroid hormone, the inability to make a usable form of parathyroid hormone or the inability of kidneys and bones to respond to parathyroid hormone production.

Hypoparathyroidism can result from congenital disorders, iatrogenic causes (e.g., drugs, removal of the parathyroid glands during thyroid or parathyroid swge1y. radiation), infiltration of the parathyroid glands (e.g., metastatic carcinoma. Wilson disease, sarcoid), suppression of parathyroid function, HIV/AIDS, or idiopathic mechanisms.

Hypocalcemia is the most important consequence of hypoparathyroidism. Symptoms occur when ionized calcium level drops to less than 2.5-3 mg/1 00 mL. The clinical manifestation is tetany. A positive Chvostek's sign (twitching of the facial muscles when tapped on the facial nerve near the parotid gland) is characteristic of hypoparathyroidism.

Important: The dental manifestations of hypoparathyroidism (i.e., delayed eruption. enamel hypoplasia and blunted root apices) may be prevented by early treatment with vitamin D.
