Calcium vitamin D supplementation

Calcium/Vitamin D supplementation Patients should receive supplemental calcium if dietary intake is inadequate. Patients at increased risk for vitamin D insufficiency (eg, those in nursing homes, chronically ill, older than 70 years of age), should receive vitamin D supplementation in addition to that provided in alendronate/cholecalciferol. Patients with Gl malabsorption syndromes may require higher doses of vitamin D supplementation consider measurement of 25-hydroxyvitamin D.

Parathyroidectomy is a treatment of last resort for sHPT, but should be considered in patients with persistently elevated iPTH levels above 800 pg/mL (800 ng/L) that is refractory to medical therapy to lower serum calcium and/or phosphorus levels.39 A portion or all of the parathyroid tissue may be removed, and in some cases a portion of the parathyroid tissue may be transplanted into another site, usually the forearm. Bone turnover can be disrupted in patients undergoing parathyroidectomy whereby bone production outweighs bone resorption. The syndrome, known as hungry bone syndrome, is characterized by excessive uptake of calcium, phosphorus, and magnesium for bone production, leading to hypocalcemia, hypophosphatemia, and hypomagnesemia. Serum ionized calcium levels should be monitored frequently (every 4 to 6 hours for the first 48 to 72 hours) in patients receiving a parathyroidectomy. Calcium supplementation is usually necessary, administered IV initially, then orally (with vitamin D supplementation) once normal calcium levels are attained for several weeks to months after the procedure. 

Adequate calcium and vitamin D intake is essential in the prevention and treatment of osteoporosis. Calcium and vitamin D supplements to meet requirements should be added to all drug therapy regimens for osteoporosis. 

Calcium and vitamin D supplementation increases bone mineral density, and the combination decreases the risk of hip and vertebral fractures. Additionally, vitamin D supplementation decreases nonvertebral fractures in older men and women living independently.11 Because of the effects of calcium on... 

Daily calcium and vitamin D requirements are highest in postmenopausal women and elderly men 1500 mg elemental calcium and 400 to 800 IU vitamin D (see Table 53-4). When these requirements cannot be achieved by diet alone, appropriate calcium and/or vitamin D supplementation is recommended. 

Pay special attention to any vitamins and calcium and vitamin D supplements the patient is taking. 

Recommend appropriate calcium and vitamin D supplementation (see Table 53-6). 

The GP made a provisional diagnosis of osteomalacia and prescribed vitamin D supplements. Vitamin D measurements are not performed routinely, but the assumption is that a low result would have been obtained on the blood sample. Most of the vitamin D necessary to maintain normal calcium homeostasis is derived from endogenous synthesis by reactions in the skin (which require UV radiation from sunlight), liver and kidney. The cultural habits of Mrs Al-Ameri required her to dress in a burqah and niqab whenever she left the home, meaning that very little of her skin was exposed to daylight.

She should be encouraged to take calcium and vitamin D supplementation immediately. She should be scheduled for baseline determination of her bone density so that any evidence of loss of bone mass can be ascertained. 

Clinical trials have demonstrated that the use of the bisphosphonates, nasal calcitonin, or human rPTH combined with calcium and vitamin D supplementation is effective in preventing drug-induced osteoporosis. Thus, individuals receiving over the long term any medication that can induce osteomalacia should also take one of these compounds and have periodic bone density determinations. 

Geriatric Considerations - Summary Primidone is poorly tolerated in older adults avoid use if possible. Dosage adjustments are required in renal impairment. Numerous drug interactions with primidone exist. Primidone may reduce bone mineral den-sitybyinterferingwith vitamin D catabolism. Calcium and vitamin D supplementation and monitoring of bone mineral density are recommended for older adults taking this drug.

Aromatase inhibitors increase bone turnover by near complete estrogen depletion, leading to reduced bone mineral density and an increased risk of fractures. Bisphosphonates plus calcium and vitamin D supplementation mitigate this (26). In an open, multicenter, randomized study in 602 women with early-stage breast cancer taking letrozole 2.5 mg/day, zoledronic acid 4 mg every 6 months prevented bone loss (27). 

In the Women s Health Initiative Calcium/Vitamin D Trial, a large number of postmenopausal women (n = 36,282) were supplemented with 1000 mg of elemental calcium and 400 IU vitamin D daily or placebo for 7 years. The study found no significant decrease in either systolic or diastolic blood pressure (Margolis et al., 2008). The results from the Women s Health Initiative Trial further emphasized the importance of dairy per se rather than calcium for the effect on blood pressure. 

Problem/lnfluence of Medication. During the postoperative period, calcium and vitamin D supplements were reinstituted to facilitate bone formation. The patient, however, soon began to experience bouts of diarrhea, apparently as a side effect of the vitamin D supplements. Consequently, the vitamin D supplements were withdrawn, and only the calcium supplement was continued. Because metabolic by-products of vitamin D accelerate the absorption of calcium from the gastrointestinal tract, both agents should be administered together. This patient, however, was apparently unable... 

Three main lines of treatment are generally accepted in idiopathic hypercalcemia of infancy the withholding of all vitamin D supplement and vitamin D-fortified food, the reduction of the intake of calcium, and the use of cortisone. 

Calcium intake through diet and, if necessary, use of supplement, should total 1,000 mg/day. In postmenopausal women not taking estrogen, total calcium intake should be 1,500 mg/day. In men and women over 65 years of age, calcium and vitamin D supplementation have been shown to reduce the risk of fracture from 13% to 6% over a three year period. This suggests that the benefits of calcium and vitamin D supplementation is clinically important for prevention of fractures due to bone loss, particularly in elderly patients. ... 

Therapy for this patient consisted of a daily supplement of elemental calcium (1000 mg) in the form of calcium carbonate. Because of the elevated concentration of 1,25-dihydroxyvitamin D and the normal concentration of 25-hydroxyvitamin D, vitamin D supplements were not prescribed for this child. The subject of this case report responded well to calcium supplementation. After 3 months of supplementation,... 

As Mrs TY has no contraindications to treatment and has not experienced a previous treatment failure, she should be started on a bisphosphonate. Calcium and vitamin D supplementation should also be initiated to ensure an adequate dietary intake. 

Consensus guidelines for the management of osteoporosis in patients with chronic liver disease recommend transdermal HRT (containing oestradiol 50 pg/day plus progestogen in women with an intact uterus) in combination with oral calcium and vitamin D supplementation, as first-line therapy. 

Consensus guidelines on the management of osteoporosis associated with chronic liver disease recommend oral calcium and vitamin D supplementation plus transdermal HRT as first-line therapy for women with established osteoporosis. Transdermal oestradiol should be used at a dose of 50 pg/day (equivalent to 2 mg daily of oral oestradiol). This should be given in combination with a progestogen in women with an intact uterus [4]. Oral bisphosphonates should be avoided in cirrhotic patients who may have portal hypertension and oesophageal varices because of their potential to precipitate a variceal bleed [4, 27],...
