Summary It has been suggested that the decrease in vitamin D stores with aging is a contributory cause of age-related osteoporosis.
We studied this question by measuring bone mineral density (BMD) of the mid-radius, distal radius, and lumbar spine assessed
by single and dual photon absorptiometry in 122 women, aged 33–94 years, selected from a random sample of Rochester, MN residents.
We measured serum 25-hydroxyvitamin D (25OHD), the major storage from of vitamin D, as well as 25OHD3 (representing both endogenous and exogenous sources of vitamin D), and 25OHD2, (representing only exogenous sources). Both baseline serum total 25OHD (r=−0.29,P<0.001) and the metabolite 25OHD3 (r=−0.41,P<0.001), were negatively associated with age at baseline. After adjusting for the effect of age by multiple regression analysis,
there was no association between serum levels of 25OHD2, 25OHD3, or total 25OHD and BMD for any of the three skeletal scanning sites. Thus, in a northern American population we cannot demonstrate
that reduced bioavailability of vitamin D plays a major role in age-related bone loss. 相似文献

Vitamin D deficiency has been reported previously in patients with osteoarthritis undergoing total hip arthroplasty. We found a high prevalence of vitamin D deficiency in elderly patients with advanced knee osteoarthritis scheduled for total knee replacement and also a significant association with a lower preoperative functional state. A review of the literature is given on vitamin D deficiency in patients with knee osteoarthritis and the association with lower outcome scores after arthroplasty is discussed. 相似文献

Children suffering severe burns develop progressive vitamin D deficiency because of inability of burned skin to produce normal
quantities of vitamin D3 and lack of vitamin D supplementation on discharge. Our study was designed to determine whether a daily supplement of a standard
multivitamin tablet containing vitamin D2 400 IU (10 μg) for 6 months would raise serum levels of 25-hydroxyvitamin D [25(OH)D] to normal. We recruited eight burned
children, ages 5–18, whose families were deemed reliable by the research staff. These children were given a daily multivitamin
tablet in the hospital for 3 months in the presence of a member of the research staff and then given the remainder at home.
At 6 months, the subjects returned for measurements of serum levels of 25(OH)D,1,25-dihydroxyvitamin D [1,25(OH)2D], intact parathyroid hormone (iPTH), Ca, P, albumin, and total protein as well as bone mass by dual energy X-ray absorptiometry.
Serum 25(OH)D levels were compared to a group of seven age-matched burned children studied at an earlier date without the
vitamin supplement but with the same method of determination of 25(OH)D at 6 months post-burn. In addition, the chewable vitamins
were analyzed for vitamin D2 content by high performance liquid chromatography. Serum concentration of 25(OH)D was 21 ± 11(SD) ng/ml (sufficient range
30–100) with only one of the eight children having a value in the sufficient range. In comparison, the unsupplemented burn
patients had mean serum 25(OH)D level of 16 ± 7, P = 0.33 versus supplemented. Serum levels of 1,25(OH)2D, iPTH, Ca, P, albumin, and total protein were all normal in the supplemented group. Vitamin D2 content of the chewable tablets after being saponified and extracted was 460 ± 20 IU. Bone mineral content of the total body
and lumbar spine, as well as lumbar spine bone density, failed to increase as expected in the supplemented group. No correlations
were found between serum 25(OH)D levels and age, length of stay, percent body surface area burn or third-degree burn. Supplementation
of burned children with a standard multivitamin tablet stated to contain 400 IU of vitamin D2 failed to correct the vitamin D insufficiency. 相似文献

Summary Previous studies demonstrated decreases in serum 25-hydroxyvitamin D in obese subjects. Studies were carried out to determine
whether serum vitamin D is low in obesity. The results indicate that serum vitamin D is significantly lower in obese than
in nonobese individuals and may contribute to lower serum 25-hydroxyvitamin D in obesity. 相似文献

Summary We assessed vitamin D nutritional status in unselected consecutive patients seeking advice on osteoporosis. The prevalence
of vitamin D depletion ranged from 15–72% depending upon the cut-off levels used for serum 25-hydroxyvitamin D, and the prevalence
did not change over the 5 years of the study.
Introduction Vitamin D depletion is a significant public health problem and has been studied in different populations using different cut-off
levels, but the optimal level is yet to be established.
Methods In a cross-sectional study of 2924 patients seen for osteoporosis advice we determined the prevalence of vitamin D depletion,
as assessed by 25-hydroxyvitamin D (25-OHD), using three different cut-off levels stratified by gender, race and the year
of the study over 5 years.
Results Mean age was 68.3 ± 10.0 years; 90% women and 88% white. Mean 25-OHD level was 24.6 ± 10 ng/ml and mean PTH was 48.4 ± 32 pg/ml.
The prevalence of vitamin D depletion was 15% with a cut-off level of <15 ng/ml, and rose to 32% and 72% with cut-off levels
<20 ng/ml and <30 ng/ml, respectively. The prevalence was higher in men and blacks and remained constant over 5 years, regardless
of the cut-off level. The expected inverse relationship between 25-OHD and PTH was observed irrespective of gender or ethnicity.
Conclusions The prevalence of vitamin D depletion in patients seeking advice for osteoporosis is high and did not change over the 5 years
of the study. 相似文献

Summary This study reports on oral treatment with different doses of vitamin D3 ranging from 25 to 200 μg in females with 25-hydroxyvitamin
D3 levels < 60 nmol/L screened for participation in an osteoporosis trial. A guidance to safely and efficiently achieve 25-hydroxyvitamin
D3 levels > 60 nmol/L is presented.
Introduction The importance of vitamin D for skeletal health has been implemented in clinical trials in osteoporosis. The threshold of
25-hydroxyvitamin D for inclusion has changed from 30 to 60 nmol/L. This study reports on oral treatment with different doses
of vitamin D3 in females with 25-hydroxyvitamin D3 levels < 60 nmol/L.
Methods In 131 postmenopausal females screened for participation in an osteoporosis trial, the 25-hydroxyvitamin D3 concentration
was < 60 nmol/L. They were treated with 25 (n = 22), 50 (n = 19), 75 (n = 19), 100 (n = 41) or 200 μg (n = 30) of vitamin D3 daily for at least 10 days.
Results In the females treated with 25, 50, 75, 100 and 200 μg of vitamin D3 daily the 25-hydroxyvitamin D3 concentrations increased
significantly from 32.4 ± 2.7 (mean ± SEM) to 50.8 ± 2.9, from 46.7 ± 2.8 to 65.8 ± 2.6, from 41.6 ± 2.7 to 67.4 ± 2.9, from
46.7 ± 1.4 to 64.4 ± 2.2 and from 42.1 ± 2.0 to 71.2 ± 2.8 nmol/L, respectively (p < 0.001). S-calcium increased significantly but within the reference range (p < 0.006).
Conclusion Oral vitamin D3 safely increased 25-hydroxyvitamin D3 concentrations in all females above 60 nmol/L. This study demonstrates
how to achieve the new recommended 25-hydroxyvitamin D concentrations within the screening period of a clinical trial. 相似文献
