What is the function of 1 25 Dihydroxycholecalciferol?
Calcitriol is the active form of vitamin D, normally made in the kidney. It is also known as 1,25-dihydroxycholecalciferol. It is a hormone which binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes.
What is the source of 1 25 Dihydroxycholecalciferol?
1,25 dihydroxyvitamin D (1,25(OH)2 D) is formed when 25(OH)D is hydroxylated by the enzyme 1α-hydroxylase (CYP27B1), which is located in the mitochondria of proximal tubules of the kidney. 1,25(OH)2 D is the biologically active form of vitamin D.
What happens if parathyroid hormone is high?
In primary hyperparathyroidism, one or more of the parathyroid glands is overactive. As a result, the gland makes too much parathyroid hormone (PTH). Too much PTH causes calcium levels in your blood to rise too high, which can lead to health problems such as bone thinning and kidney stones.

Calcitriol topical ointment is used to treat mild to moderate plaque psoriasis, which is a skin disease with red patches and white scales that do not go away. Calcitriol is a form of vitamin D.
Can calcitriol damage kidneys?
Inactivating mutations in this gene cause idiopathic infantile hypercalcaemia with highly elevated levels of calcitriol, which can cause massive nephrocalcinosis and subsequent loss of kidney function [16].
Does calcitriol affect kidneys?
Circulating calcitriol, a key metabolite in maintaining calcium and phosphorus homeostasis, is produced in the kidney. In kidney failure, calcitriol levels progressively decrease, contributing to the development of renal secondary hyperparathyroidism (SHPT).
What should I do if my calcium is high?
If your calcium levels are very high, you’ll need to go to the hospital to get fluids and medicine called diuretics through your veins. This can treat hypercalcemia fast….They may also tell you to:

- Stop taking thiazide diuretics or lithium.
Why would my calcium be high?
