Vitamin D Deficiency

Undiagnosed Vitamin D Deficiency in the Hospitalized Patient - Article

ABSTRACT: Vitamin D deficiency among hospitalized patients may be more widespread than realized. Vague musculoskeletal complaints in these chronically ill patients may be attributed to multiple underlying disease processes rather than a deficiency in vitamin D. However, the failure to diagnose an underlying deficiency places the patient at risk for continued pain, weakness, secondary hyperparathyroidism, osteomalacia, and fractures. The causes of hypocalcemia and hypophosphatemia in the chronically ill patient are many, and the patient may respond to simple replacement therapy. Elderly hospitalized patients with ionized hypocalcemia and hypophosphatemia, with or without an elevated parathyroid hormone level, are most likely deficient in vitamin D. Initiating treatment during hospitalization is reasonable once the diagnosis has been confirmed by finding a low 25-hydroxyvitamin D level. Treatment with high doses of vitamin D is safe. Unfortunately, some hospital formularies continue to provide multivitamin supplements that contain less vitamin D than currently is recommended.

Recognition and Management of Vitamin D Deficiency - Article

ABSTRACT: Vitamin D deficiency affects persons of all ages. Common manifestations of vitamin D deficiency are symmetric low back pain, proximal muscle weakness, muscle aches, and throbbing bone pain elicited with pressure over the sternum or tibia. A 25-hydroxyvitamin D level should be obtained in patients with suspected vitamin D deficiency. Deficiency is defined as a serum 25-hydroxyvitamin D level of less than 20 ng per mL (50 nmol per L), and insufficiency is defined as a serum 25-hydroxyvitamin D level of 20 to 30 ng per mL (50 to 75 nmol per L). The goal of treatment is to normalize vitamin D levels to relieve symptoms and decrease the risk of fractures, falls, and other adverse health outcomes. To prevent vitamin D deficiency, the American Academy of Pediatrics recommends that infants and children receive at least 400 IU per day from diet and supplements. Evidence shows that vitamin D supplementation of at least 700 to 800 IU per day reduces fracture and fall rates in adults. In persons with vitamin D deficiency, treatment may include oral ergocalciferol (vitamin D2) at 50,000 IU per week for eight weeks. After vitamin D levels normalize, experts recommend maintenance dosages of cholecalciferol (vitamin D3) at 800 to 1,000 IU per day from dietary and supplemental sources.
