The serum concentration of vitamin D will only give information about the recent exposure to either nutritional vitamin D or to recent vitamin D production in the skin. Within hours vitamin D is removed from the circulation and reappears again a few hours later as 25(OH)D. Measurements of vitamin D therefore are not useful to judge the vitamin D status

[Rational and results of weekly treatment with calcidiol in postmenopausal and senile osteoporosis].
Minerva medica, 2007Vitamin D plays a crucial role for the prevention and treatment of both postmenopausal and senile osteoporosis and possibly for a number of other conditions. The prevalence of vitamin D deficiency remains extremely high among elderly subjects. This indicates that both the perception of the problem and the interventions so far implemented remain ...

Journal of Chromatography B: Biomedical Sciences and Applications, 1987
A system is described using high-performance liquid chromatography to separate and quantify, by spectrophotometry in a simple one-stage procedure, ercalcidiol (25-hydroxyvitamin D2) and calcidiol (25-hydroxyvitamin D3). The novel feature of the method is the employment of an ultraviolet-absorbing internal standard to monitor recovery.

Parathyroid hormone, calcidiol, calcitriol and adverse events in the acute coronary syndrome
Medicina Intensiva (English Edition), 2018To know the clinical profile as well as the prognostic significance of elevated levels of parathyroid hormone (PTH) in patients admitted for acute coronary syndrome (ACS).Observational and prospective study of patients admitted for ACS in a single Spanish center during a period of six months.The circulating concentrations of PTH, calcidiol, calcitriol,

Optimal serum calcidiol concentration for cancer prevention.
Anticancer research, 2012It has been demonstrated in several studies that serum calcidiol (25 OH vitamin D(3)) concentration is in a reversed and linear relationship with cancer risk. However, there are also studies showing no such association and some even suggest the opposite. The risk of pancreatic and oesophageal cancer seems to increase, when serum calcidiol concentration

[Why and how correct calcidiol deficiency in haemodialysis patients?].
Nephrologie & therapeutique, 2010The plasma concentration of 25(OH) D - calcidiol - is low in most of stage 5 renal patients. Due to the lack of renal 1alpha-hydroxylase, no supplementation is recommended. However, calcidiol also displays many extraosseous beneficial antiproliferative effects. It may be useful to correct its deficiency in dialysis patients.

Clinical Use of Vitamin D Metabolite Assays (Calcidiol and Calcitriol)
1990Vitamin D was recognized at the beginning of this century as a simple vitamin derived either from fatty food or produced in the skin from 7-dehydrocholesterol under the influence of the shortest waves of ultraviolet light of the sun. After intensive research during the past 2 decades, vitamin D has outgrown its simple status to become a complex series ...
