elevated calcitriol levels

We brought her in for dental work and the blood tests showed high creatinine and urea. Her phosperus levels are normal with elevated calcium. She is showing no signs of sickness. Her appetite is great, lots of energy, etc. 4 years ago another blood test showed the same calcium levels but normal kidney function. My vet(s) are confused by the test results. All her other blood tests are normal (sodium, pot, protein, etc) We are giving her subcutaneous fluids, a kidney diet and some probiotics.

I have recently been reading a piece about calcitriol, which is a form of vitamin D that promotes the level of calcium in a canine body. This is not a new initiative in the treatment of kidney failure in dogs - and certainly should not be introduced without precautions - but it does have some promising effects.

These cells express CYP27B1, the gene encoding for the enzyme responsible for the synthesis of the vitamin D hormonally active metabolite, calcitriol. Treatment with vitamin D(3) resulted in calcitriol production and induction of calcitriol target gene CYP24A1, indicating that these cells contain the full machinery for vitamin D metabolism and activity. Notably, treatment with calcitriol resulted in HCV inhibition.

25 mcg), although at my Endo appointment 2 weeks ago we agreed that I could just do 1 calcitriol 1x per day but that if I started feeling any tingling or anything to start taking the calcitriol again. My Vit D levels are still a little low but are improving and calcium levels are staying in the normal range, my parathyroid is in the normal range but still low so that's why the Dr. didn't want to reduce any of the other meds yet, just slowly weaning me off. Every Dr.

Treatment with vitamin-D(3) resulted in calcitriol production and induction of calcitriol target gene CYP24A1, indicating that these cells contain the full machinery for vitamin-D metabolism and activity. Notably, treatment with calcitriol resulted in HCV inhibition. Collectively, these findings suggest that vitamin-D(3) has an anti-viral activity which is mediated by its active metabolite.

Such studies generally find that rates drop rapidly as vitamin D levels rise above 5-10 ng/mL (12-25 nmol/L), then more slowly until levels of 40 ng/mL (100 nmol/L) are reached. How vitamin D works: Vitamin D blocks the growth of cancer tumors. The active form of vitamin D, calcitriol, does most of the work. Calcitriol is made in the liver and in various organs affected by cancer.

parathyroid failure after 3 years post TT? by LLV123, 4 minutes ago Hi, I had TT 3 years ago, had 1 para removed accidentally, 1 re implanted, 2 were "fine" Had low Ca post TT for a few weeks, then ok. Now, 3 years later, had some muscle twitching, had low ionized Ca {1.09, 1.10, 1.14 after I had infusions for 3 days of IV CA. Serum was ok, not high but low 8's. My endo put me on Calcitriol and said para's are failing. NO WAY!!

Ever since she has this terrible feeling of electricity going through her body. She was told it is in connection with calcium intake levels. It is taking what appears to be an inordinate amount of time to balance whatever it is that is creating this presentation. Referrals to specialists to fix it are far off when a person is in such great discomfort. Is there anything that can be done in the meanwhile? Why does this happen? Is it common?

Had a TT 5+ weeks ago. Was told my parathyroids were not touched and my calcium levels have been really good. Dr had me take .25 mg of calcitriol daily for 4 weeks; just weaned down to .25mg every other day. Taking 2000 mg of calcium a day plus whatever I get in my diet. My most recent serum calcium test came in at .88 which my Dr says is below normal and he's concerned. Is it usual for your parathyroids to stop working so long after surgery?

I received a call from my doctor saying my vitamin d levels are low. She did not give me the range. I have hypoparathyroidism due to surgery i take 50mcg's of calcitriol a day to mantain calcium level. She wants me to add another 25mcg's of calcitriol because my vitamin d is low. Does that sound right? Because i would think that the test she did would have to be specific looking at the active and inactive forms of vitamin d. I dont know what to do but i dont think she is right..

Calcitriol is currently available for dogs and cats in kidney failure and veterinarians order it through various compounding pharmacies. Calcitriol is compounded specifically for each pet according to their body weight and BUN-Creatinine levels. It is given to pets as a capsule by mouth once a day.

As long as you understand that patients can have primary hyperparathyroidism with normal calcium levels or normal PTH levels, you will be able to make the diagnosis in almost every case. Remember, it is almost never normal to have high calcium levels, and this should typically be worked up with the presumption that a parathyroid tumor is present. Also remember that calcium AND PTH levels in normal patients are very constant from week to week, measure to measure...

The tingling, burning sensation, the muscle spasms and so on. However, my blood test have shown normal calcium levels. I'm currently take my medication as prescribed, but I still have these symptoms. So I'm wondering if long term hypothyroidism can cause hypocalcemia and if a person could have hypocalcemia when calcium levels are within normal range on regular blood test? Or is there a special blood test which test for hypocalcemia?

drs keep saying magnesium and potassium low had nothing to do with thyroidectomy but how is this possible...niw that I got all three levels are back up but wondering every day if they may go back down is pure torture...ever heard of this???

I am taking 800-1000mg daily of Citracal, and Calcitriol .25 twice a day. They checked my PTH level and it was undetectable. I also had low phosphorus levels. I am worried about it happening again since I don't know why it happened. The only symptom I really had was menstrual-type cramping.

t want to do radiation because I have a little one at home. My calcium levels plummeted at the hospital that I needed to stay 4 nights. I was discharged with a level of 7.5. I went back the next day for follow up lab. My levels dropped again. They increased my calcium dosage to 3 pills of cal vit d 4 times a day and citricol 2 times a day. Will I ever be normal or regulated again? I want more children and I just feel with surgery I screwed myself.

I spent five days in the hospital, thanks to issues with my calcium levels. I could not get above 7.5. I was sent home with instructions to take calcium supplements, but still I have tingling and burning and muscle cramps. It is agony, especially at night. My surgery took three hours, and the only pain I had was the sore throat. Not sure if that was from the anesthesia or the surgery, but it lasted about four days. The incision isn't that painful, and I am still pulling off steri strips.

My concern is the vitamin d lab she ran. The doctor states my vitamin d is low. How is that possible on calcitriol? Also she wanted me to increase my calcitriol but what does that blood test measure? Active or inactive vitamin d?

Vieth recommends a daily dose of 4,000 IU/day in order to maintain blood levels above 100nmol/L. He also clarifies that published cases of vitamin D causing elevated blood calcium (hypercalcaemia) have involved daily intake of 40,000 IU. Hypercalcaemia due to excessive vitamin D is generally accompanied by blood concentrations greater than 88ng/ml (220 nmol/L). Dr.

s lots of things that can cause elevated blood calcium levels...if the PTH (parathyroid hormone level) and the calcium level are both elevated, it's usually caused by primary hyperparathyroidism...(This is usually caused by a tumor on a parathyroid gland) All the four parathyroid glands do are regulate the blood calcium levels...When the blood calcium is high, the PTH should be low or near normal...

It really depends. . .I had my total thyroidectomy on 8/4 and had a calcium crash a few days later. After being in the hospital for a week on an IV calcium drip, I was released on massive amounts of calcitriol (Prescription vit. ) & calcium. I am now down to manageable levels of calcium (3 a day) and my doctor wants me off of the calcitriol. . .

so. . .after my TT on 8/4/08, I had severe hypocalcemia. . .ended up back in the hospital for a week on iv calcium drip etc. etc. etc. i had an appointment with the endo today (Friday 9/19/08), and my calcium numbers were good: 9.6 totally normal he actually told me to stop taking the calcitriol, but when he tapped my face to do the "Chvostek's Sign", my lips spasmed. . .
