Wintertime Vitamin D Supplementation Inhibits Seasonal Variation of Calcitropic Hormones and Maintains Bone Turnover in Healthy Men

Vitamin D is suggested to have a role in the coupling of bone resorption and formation. Compared with women, men are believed to have more stable bone remodeling, and thus, are considered less susceptible to the seasonal variation of calcitropic hormones. We examined whether seasonal variation exists in calcitropic hormones, bone remodeling markers, and BMD in healthy men. Furthermore, we determined which vitamin D intake is required to prevent this variation. Subjects (N = 48) were healthy white men 21–49 yr of age from the Helsinki area with a mean habitual dietary intake of vitamin D of 6.6 ± 5.1 (SD) μg/d. This was a 6‐mo double‐blinded vitamin D intervention study, in which subjects were allocated to three groups of 20 μg (800 IU), 10 μg (400 IU), or placebo. Fasting blood samplings were collected six times for analyses of serum (S‐)25(OH)D, iPTH, bone‐specific alkaline phosphatase (BALP), and TRACP. Radial volumetric BMD (vBMD) was measured at the beginning and end of the study with pQCT. Wintertime variation was noted in S‐25(OH)D, S‐PTH, and S‐TRACP (p < 0.001, p = 0.012, and p < 0.05, respectively) but not in S‐BALP or vBMD in the placebo group. Supplementation inhibited the winter elevation of PTH (p = 0.035), decreased the S‐BALP concentration (p < 0.05), but benefited cortical BMD (p = 0.09) only slightly. Healthy men are exposed to wintertime decrease in vitamin D status that impacts PTH concentration. Vitamin D supplementation improved vitamin D status and inhibited the winter elevation of PTH and also decreased BALP concentration. The ratio of TRACP to BALP shows the coupling of bone remodeling in a robust way. A stable ratio was observed among those retaining a stable PTH throughout the study. A daily intake of vitamin D in the range of 17.5–20 μg (700–800 IU) seems to be required to prevent winter seasonal increases in PTH and maintain stable bone turnover in young, healthy white men.     

Effect of immobilization upon renal synthesis of 1,25-dihydroxyvitamin D in disabled elderly stroke patients

A 1,25-dihydroxyvitamin D [1,25-(OH)2D] deficiency and immobilization-related increased serum calcium concentration have been observed in hemiplegic stroke patients. To elucidate the influence of increased serum calcium concentration on bone metabolism, we measured serum biochemical indices and bone mineral density (BMD) in the second metacarpals of 170 elderly subjects with hemiplegic stroke and 72 age-matched healthy controls. Serum concentrations of 25-hydroxyvitamin D [25-(OH)D], 1,25-(OH)2D, ionized calcium, intact parathyroid hormone (PTH), intact bone Gla protein (BGP), and pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) were measured. An increased serum calcium concentration (mean 2.543 mEq/L) was observed in this population and correlated negatively with the Barthel index (mean 66), indicating immobilization-induced bone resorption with consequent increased serum calcium. Decreased serum concentrations of 1,25-(OH)2D (mean 25.0 pg/mL) and serum 25-OHD concentration (mean 11.6 ng/mL) were noted. Serum PTH was not increased (mean 34.8 pmol/L). Serum levels of BGP were decreased significantly, whereas serum ICTP concentrations were elevated (mean 15.2 ng/mL). A strong negative correlation was seen between the serum calcium concentration and 1,25-(OH)2D (p < 0.0001). BMD of the second metacarpal in patients was decreased significantly compared with control subjects and highly correlated with 25-(OH)D and 1,25-(OH)2D concentrations. Immobilization-related increased serum calcium levels may inhibit PTH secretion, and thus 1,25-(OH)2D production. In addition, 25-(OH)D insufficiency also may contribute to decreased concentration of 1,25-(OH)2D.

Beneficial effect of intermittent cyclical etidronate therapy in hemiplegic patients following an acute stroke.

Significant decreases in bone mineral density (BMD) occur on the hemiplegic side in chronic stroke patients, which correlate with the degree of paralysis and hypovitaminosis D. In this double-blind, randomized, and prospective study of 98 patients with hemiplegia involving both an upper and lower extremity (55 males and 53 females; mean age, 71.4 +/- 0.6 years) after an acute stroke, 49 were given etidronate for 56 weeks and 49 received a placebo. The BMD was measured by computed X-ray densitometry (CXD) of the second metacarpal bone bilaterally. Forty age-matched control subjects were followed for 56 weeks. At baseline, both groups had 25-hydroxyvitamin D [25(OH)D] insufficiency, increased serum ionized calcium and pyridinoline cross-linked carboxy-terminal telopeptide of type I collagen (ICTP), and low serum concentrations of parathyroid hormone (PTH) and 1,25-dihydroxyvitamin D [1,25(OH)2D], suggesting immobilization-induced hypercalcemia and inhibition of renal synthesis of 1,25(OH)2D. The BMD on the hemiplegic side decreased by 2.3% and 4.8% in the etidronate and placebo groups, respectively (p = 0.0003). After treatment, the serum 1,25(OH)2D concentration increased by 62.2% in the etidronate group and decreased by 12.4% in the placebo group. The etidronate group had significant decreases in the serum ionized calcium and ICTP and increases in PTH and bone Gla protein (BGP), whereas the placebo group had higher serum calcium and ICTP concentrations but stable PTH. These results suggest that etidronate can prevent decreases in the BMD in hemiplegic stroke patients because it decreases the serum calcium through inhibition of bone resorption and causes a subsequent increase in the serum 1,25(OH)2D concentration.     

老年患者25( OH) D、PTH与骨折的相关分析

Role of Parathyroid Hormone in Bone Fragility of Postmenopausal Women with Vitamin D Insufficiency

Vitamin D insufficiency is related to an increase in PTH, which might be critical for an increase in bone fragility. However, the role of endogenous PTH in vitamin D insufficiency-induced fracture risk remains unclear. The present study was performed to examine the relationships among vitamin D insufficiency, bone fragility, and PTH in 202 Japanese postmenopausal women. Serum 25-hydroxyvitamin D (25[OH]D) levels were measured. The percentages of subjects with 25(OH)D levels below 10, 15, and 20 ng/ml were 5.0, 41.0, and 80.7%, respectively. Serum 25(OH)D levels were negatively related to age and serum levels of Cr and PTH; they were positively related to bone mineral density (BMD). In multiple regression analysis, BMD was significantly related to 25(OH)D levels when adjusted for age, body mass index (BMI), and serum levels of Cr and PTH. Multiple logistic regression analysis showed that lower 25(OH)D levels were significantly related to prevalent fracture risk when adjusted for age, BMI, serum levels of Cr and PTH, as well as femoral neck BMD. The proportion of subjects with prevalent fractures was significantly higher in the group with lower PTH and lower 25(OH)D than in the group with lower PTH and higher 25(OH)D or higher PTH and higher 25(OH)D. In conclusion, vitamin D insufficiency was found to be related to prevalent fracture risk independently of PTH. Functional hypoparathyroidism, rather than functional hyperparathyroidism, might be a risk factor for bone fragility in vitamin D insufficiency.
