AIM To evaluate the efficacy and safety of an annual intramuscular injection of cholecalciferol for vitamin D deficiency. DESIGN Prospective open-label study. PARTICIPANTS Five men and 45 women (mean age 66.3 years) with vitamin D deficiency who were given a single therapeutic intramuscular injection of 600 000 IU (15 mg) cholecalciferol (vitamin D(3)). OUTCOME MEASURES Serum levels of ca...
IMPORTANCE Experts debate optimal 25-hydroxyvitamin D (25[OH]D) levels for musculoskeletal health. OBJECTIVE To compare the effects of placebo, low-dose cholecalciferol, and high-dose cholecalciferol on 1-year changes in total fractional calcium absorption, bone mineral density, Timed Up and Go and five sit-to-stand tests, and muscle mass in postmenopausal women with vitamin D insufficiency. ...
chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. vitamin d is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. this study was performe...
Vitamin D deficiency, observed mainly in the geriatric population, is responsible for loss of bone mass and increased risk of bone fractures. Currently, recommended doses of cholecalciferol are advised, but since there are few studies evaluating the factors that influence the serum levels of 25-hydroxyvitamin D (25(OH)D) following supplementation, we analyzed the relationship between the increa...
Four experiments were conducted to investigate the effects of ultraviolet (UV) light exposure and several cholecalciferol metabolites on the development of tibial dyschondroplasia (TD) and other parameters associated with vitamin D metabolism in chickens selected for high (HTD) and low (LTD) incidence of TD. In Experiment 1, exposure of chickens to UV light reduced the incidence and severity of...
Vitamin D has garnered much research and debate about supplementation in recent years, not only as it pertains to patients with kidney disease but also to those in the general population. This review discusses observational and available clinical trial evidence about the effects of both calcitriol and vitamin D analogs (active) and ergocalciferol and cholecalciferol (nutritional) vitamin D in p...
Plasma 25-hydroxy-cholecalciferol (25-OHD) was measured serially in two groups of preterm infants receiving either 400 IU or 1000 IU oral vitamin D3 daily. All the babies were able to absorb and hydroxylate vitamin D3 adequately by 36 weeks' gestational age. The higher daily supplement had no advantage over the lower dose.
BACKGROUND Care of elderly patients after hip fracture is not well established. METHODS We enrolled 173 patients with acute hip fracture who were 65 years or older (79.2% women; mean age, 84 years; 77.4% living at home). Using a factorial design, we randomly allocated patients to extended physiotherapy (PT) (supervised 60 min/d during acute care plus an unsupervised home program) vs standard ...
