AbstractObjectiveChronic vitamin D deficiency has been associated in some patients with diffuse musculoskeletal pain. These unspecific symptoms may partly explain why vitamin D deficiency is often diagnosed late. Our aim was to analyse health-care claims after vitamin D supplementation in patients likely to have vitamin D deficiency.DesignAmbulatory health-care claims were compared before and after a vitamin D supplementation prescribed following a 25-hydroxyvitamin D assay.SettingHealth Insurance Fund (FHIF) database of the Rhône-Alpes area, France.SubjectsAmong patients reimbursed for a 25-hydroxyvitamin D assay between 1 December 2008 and 31 January 2009, those supplemented with vitamin D after the assay were matched on the date of assay to patients who did not receive vitamin D.ResultsAmong the 3023 patients who had a 25-hydroxyvitamin D assay, 935 were consequently supplemented and matched to 935 patients not supplemented. Their median age was 50·0 and 49·5 years, respectively. Patients supplemented decreased their muscle relaxant consumption whereas no change was observed in the reference group, the difference between the two groups was significant (P=0·03). Second and third Pain Relief Ladder prescriptions decreased in both groups but not significantly differently between groups (P=0·58). There was a decrease in prescriptions of biological examination in both groups with no significant difference.ConclusionsBesides a decrease in muscle relaxant prescriptions in the supplemented group, it was difficult to assess the impact of vitamin D supplementation in patients likely to have vitamin D deficiency. Prospective cohort studies and randomized trials are needed to assess the efficiency of screening and supplementing vitamin D deficiency.

Background. Vitamin D deficiency is a common problem among patients on continuous ambulatory peritoneal dialysis (CAPD). Vitamin D supplementation leads to reduced serum parathyroid hormone levels and improved cardiovascular markers. Different doses and time intervals of oral vitamin D supplementation may differ in each patient on dialysis. The study aimed to evaluate the efficacy of weekly split and single dose of ergocalciferol at 60,000 IU on serum 25-hydroxyvitamin D (25(OH)D) among patients on CAPD. Methods. A randomized study was conducted among patients on CAPD with vitamin D deficiency or insufficiency (25(OH)D < 30 ng/mL). Patients were randomly assigned to two groups: the split dose group was given ergocalciferol 20,000 IU three times weekly and the single dose group was given ergocalciferol 60,000 IU once weekly for 8 weeks. Main outcomes measured serum 25(OH)D concentrations, serum calcium, serum phosphate, and intact parathyroid levels at 8 weeks after being enrolled. Results. Of 128 screened patients, 50 met the criteria for eligibility and were randomized. At 8 weeks after treatment, mean serum 25(OH)D concentrations significantly increased from baseline 22.7 ± 5.9 to 29.5 ± 9.5 ng/mL P = 0.004 in the split dose group and 22.9 ± 5.3 to 31.2 ± 12.3 ng/mL P = 0.003 in the single dose group. No significant change was found in increase of serum 25(OH)D between the two groups P = 0.561 . At the end of study, a similar proportion of patients in both groups reached the desirable serum concentration of 25(OH)D ≥ 30 ng/mL (60% in the single group vs. 40% in the split group, P = 0.258 ). No significant cases of hypercalcemia, hyperphosphatemia, or serious adverse events occurred during the study. Conclusion. Weekly single and split doses of ergocalciferol 60,000 IU achieved similar effects on serum 25(OH)D levels among patients on CAPD with vitamin D insufficiency or deficiency, suggesting that weekly single dose would be prescribed for adequate vitamin D repletion. This trial is registered with TCTR20200821005.

Purpose: To investigate the effect of weekly single high dose vitamin D supplementation on serum 25-hydroxyvitamin D [25(OH)D], and non-specific musculoskeletal pain in female nurses. Methods: In this prospective study in Kashan/Iran, from April 1, 2014, through September 30, 2014, the 150 nurses with vitamin D deficiency received the weekly pearls of 50,000 units of vitamin D3 for 10 weeks. The serum level of 25(OH)D was measured before and after supplement therapy. The subjects were also asked to complete the Extended Nordic Musculoskeletal Questionnaire. All analyses were conducted with SPSS version 16. Results: After 10 weeks of intervention there was [Formula: see text][Formula: see text]ng/mL increase in 25(OH)D. The 82 nurses (54.7%) had 25(OH)D in normal range, while the 68 nurses (45.3%) were still vitamin D deficient. Weight could explain 15.4% increase in 25(OH)D. Before intervention 135 (90%), of nurses reported musculoskeletal pain in at least one region, after intervention this number decreased to 72.7%. There was a statistically significant improvement in musculoskeletal pain in neck, shoulders, upper back, lower back, hips/tights, knees, and ankles/feet after intervention. Conclusions: The weekly single high dose of vitamin D for 10 weeks could resolve vitamin D deficiency in about half of the patients. Patients with non-specific musculoskeletal pain might benefit from vitamin D supplementation.

AbstractThe etiology of endemic rickets was discovered a century ago. Vitamin D is the precursor of 25-hydroxyvitamin D and other metabolites, including 1,25(OH)2D, the ligand for the vitamin D receptor (VDR). The effects of the vitamin D endocrine system on bone and its growth plate are primarily indirect and mediated by its effect on intestinal calcium transport and serum calcium and phosphate homeostasis. Rickets and osteomalacia can be prevented by daily supplements of 400 IU of vitamin D. Vitamin D deficiency (serum 25-hydroxyvitamin D <50 nmol/L) accelerates bone turnover, bone loss, and osteoporotic fractures. These risks can be reduced by 800 IU of vitamin D together with an appropriate calcium intake, given to institutionalized or vitamin D–deficient elderly subjects. VDR and vitamin D metabolic enzymes are widely expressed. Numerous genetic, molecular, cellular, and animal studies strongly suggest that vitamin D signaling has many extraskeletal effects. These include regulation of cell proliferation, immune and muscle function, skin differentiation, and reproduction, as well as vascular and metabolic properties. From observational studies in human subjects, poor vitamin D status is associated with nearly all diseases predicted by these extraskeletal actions. Results of randomized controlled trials and Mendelian randomization studies are supportive of vitamin D supplementation in reducing the incidence of some diseases, but, globally, conclusions are mixed. These findings point to a need for continued ongoing and future basic and clinical studies to better define whether vitamin D status can be optimized to improve many aspects of human health. Vitamin D deficiency enhances the risk of osteoporotic fractures and is associated with many diseases. We review what is established and what is plausible regarding the health effects of vitamin D.

Objectives: Obesity has been mentioned as a high risk factor for Vitamin D deficiency (VDD) requiring supplementation in Indian children. Material and Methods: Forty obese and age-matched non-obese subjects (age 5–18 years) were assessed for lifestyle parameters, metabolic profile, and serum 25-hydroxyvitamin D (25OHD). VDD was defined as serum 25OHD < 12 ng/mL. Results: Mean 25OHD was comparable among obese and controls (15.0 ± 9.95 and 15.1 ± 4.79 ng/mL; P = 0.97) with VDD seen in 82% of cases and 85% of controls. Pubertal cases had lower 25OHD values than prepubertal obese cases (10.78 ± 4.69 and 17.2 ± 11 ng/mL; P = 0.06). Mean duration of physical activity (<2 h/week) and screen time (>2 h/day) was similar across prepubertal and pubertal groups and between obese and controls. Obesity was not associated with risk for VDD among cases and controls (odds ratio 0.83, 95% C.I. 0.25–2.7, P = 0.76). Conclusion: Obese pubertal subjects were more at risk for VDD than prepubertal subjects. Routine Vitamin D supplementation to obese Indian children may be considered during adolescence.

Aims. Kidney disease was found to be a major risk factor for vitamin D deficiency in a population study of patients hospitalized. The aims of the study were to describe the prevalence of vitamin D deficiency inpatients and outpatients in a nephrology department during fall and to evaluate effect of assessing serum 25-hydroxyvitamin D (25(OH)D) levels and previous supplementation of cholecalciferol on vitamin D status.Methods. We studied 280 subjects in total, between October and January. The subjects were recruited from the following two groups: (a) inpatients and (b) outpatients in nephrology unit. We examined previous documentary evidence of vitamin D supplementation of the patients.Results. The prevalence of vitamin D deficiency among these 280 patients was 62,1% (174 patients). Fifty-three patients (18.9%) had severe vitamin D deficiency, 121 patients (43.2%) moderate vitamin D deficiency, and 66 patients (23.6%) vitamin D insufficiency. In logistic regression analysis female gender, not having vitamin D supplementation history, low serum albumin, and low blood urea nitrogen levels were significant independent predictors of vitamin D deficiency while no association of vitamin D deficiency with diabetes mellitus, serum creatinine, eGFR, and being hospitalized was found.Conclusion. Vitamin D deficiency, seems to be an important problem in both inpatients and outpatients of nephrology. Monitoring serum 25(OH)D concentrations regularly and replacement of vitamin D are important. Women in Turkey are at more risk of deficiency and may therefore need to consume higher doses of vitamin D.

Abstract Objectives Known as ‘sunshine vitamin’, sun exposure is a major and natural source of vitamin D. This study aimed to investigate the effects of moderate sun exposure and vitamin D supplementation on vitamin D concentration among Malay women in Kelantan, Malaysia. Methods A quasi-experimental study design was carried out among female indoor workers with vitamin D deficiency (serum 25-hydroxyvitamin D &lt; 50 nmol/l) for 12 weeks to evaluate the effects of moderate sun exposure (n = 19; 15 minutes sun exposure biweekly on face, lower arms, hands and feet), vitamin D supplementation (n = 15; 50 000 IU cholecalciferol weekly) and placebo (n = 15) on serum 25-hydroxyvitamin D (25(OH)D) levels. Data was collected twice from each respondent, firstly during baseline and secondly during endpoint. Body composition measurements (body fat percentage and body mass index), fasting blood test (serum 25(OH)D level) and questionnaire (socio-demographic, physical activity and dietary vitamin D intake) were conducted. The vitamin D classification was based on the 2011 Endocrine Society Clinical Practice Guidelines. Repeated measure ANOVA within group analysis was applied. Results The baseline characteristics did not differ significantly among study groups except for age (F = 6.15, p = 0.004). After 12 weeks, serum 25(OH)D levels increased significantly in sun exposure (mean difference (MD) = 14.27 nmol/l, p &lt; 0.001) and vitamin D supplement group (MD = 14.30 nmol/l, p &lt; 0.001) but not in the placebo group (MD = 1.63 nmol/l, p = 0.067). Conclusions The 12-weeks intervention with moderate sun exposure and vitamin D supplementation showed a similar significant increment in serum 25(OH)D levels. However, no changes in serum 25(OH)D was observed in the placebo group. These results showed that sunlight exposure and vitamin D supplement were equally helpful in improving serum 25(OH)D levels in participants with vitamin D deficiency.

Weight Loss Success

The incidence of vitamin D deficiency is increasing and 25-hydroxyvitamin D (25OHD) levels, which are inversely associated with measures of obesity, are lower in overweight and obese populations. There have been several studies that have investigated the effect of vitamin D supplementation on weight loss, and studies combining weight loss interventions with increased vitamin D intake, either through supplementation or foods fortified with vitamin D. 25OHD levels have also been measured before and after weight loss to see if they improve and if the changes in 25OHD levels are related to the degree of weight loss. Some studies have suggested that vitamin D status is associated with weight loss success, with supplementation resulting in weight loss, or higher baseline 25OHD or greater increases in 25OHD levels associated with greater weight loss, although this has not been shown in all studies.

e19025 Background: Vitamin D (VitD) is synthesized in the skin as a result of exposure to sunlight and its deficiency is common in the general population as well as in cancer patients. Sun protection is strongly recommended for patients after a melanoma diagnosis. We conducted a pilot study to assess the prevalence of VitD deficiency and the impact of both sun protective behavior and VitD supplementation on VitD levels in melanoma patients Methods: Adult patients with AJCC Stage 0-III melanoma were recruited from the Washington Cancer Institute between July 2011 and January 2012. Subjects completed a questionnaire asking about oral VitD supplementation and sun protective behaviors. VitD deficiency was defined by a 25-hydroxyvitamin D (25(OH)D) level less than 30ng/mL. Pearson Chi-square test and multivariate logistic regression were used to determine predictors of VitD deficiency. Results: A total of 49 participants (20 males, 29 females) completed the questionnaire and provided a blood sample for 25(OH)D determinations. Median age was 52 years (23-82), and most (n=48, 98%) were Caucasian. The majority had either stage 0 (n= 13, 27%) or 1 (n=29, 59%) melanoma. Twenty-six (53%) reported regular use of VitD supplements, and the majority reported sun protective behaviors (n=36, 73%). The prevalence of VitD deficiency was 46% (n=23). VitD deficiency was more common in patients who were not taking VitD supplementation (73% vs. 26%, p<0.01). Other associations include: (1) BMI>25 vs. BMI ≤25 (57% vs. 33%, p=0.10); (2) winter vs. summer months(54% vs. 40%, p=0.34); (3) those who practiced sun protective behavior vs. not (50% vs. 38%, p=0.48). On multivariate analysis, the use or non-use of VitD supplementation remained the only significant predictor of VitD deficiency (OR=0.11, p<0.01). Conclusions: VitD deficiency is common in melanoma patients especially in those who are not on VitD supplementation.

Abstract Background: The exact relationship between 25-hydroxyvitamin D [25(OH) D] levels and small vessel disease (SVD) are not clear in China. The aim of this study was to determine the association between 25(OH) D and SVD in China. Methods: We enrolled consecutive 106 patients with SVD and 115 controls in Beijing Chaoyang Hospital and Jinan City people’s hospital between Jan 2017 and Dec 2017. Vitamin D status was estimated by measuring serum 25-hydroxyvitamin D [25(OH) D]. The subjects were categorized into three subgroups: vitamin D deficiency (≤12ng/ml), insufficiency (12-20ng/ml) and sufficiency (≥20 ng/ml). Results: Among 106 stroke patients, 80 (75.5%) were men and mean age was 61.6±13.2 years. 25(OH) D deficiency was observed in 76 (71.7%) stroke patients and 47 (40.9%) controls (P=0.001). Comparing with controls, patients with SVD were correlated with higher proportion of male, the histories of stroke, smoking and hyperlipidemia; higher systolic blood pressure, diastolic blood pressure and low density lipoprotein; lower of 25(OH)D level. The logistic regression analysis showed the level of 25(OH)D was independently predicted the occurrence of SVD (OR 0.772, CI 0.691-0.862, P=0.001). Compared with those in sufficiency group (≥20ng/ml), the ORs of SVD in the deficiency (≤12ng/ml) and insufficiency group (12–20 ng/ml) of 25(OH)D were 5.609 [95% confidence interval (CI) 2.006-15.683] and 1.077 (95% CI: 0.338-3.428) after adjusting for potential confounders, respectively. We also found a significant effect modification of SVD risk by 25(OH)D status and hypertension interaction (P=0.001), and compared with those with sufficiency 25(OH)D levels, in hypertensives with vitamin D deficiency (≤12ng/ml) and insufficiency (12-20 ng/ml), the ORs were increased to 9.738 (2.398-39.540) and 1.108 (0.232-5.280), respectively (Pinteraction=0.001). Conclusion: Our findings showed patients with SVD were correlated with the deficiency of 25(OH)D. The combined presence of hypertension and vitamin D deficiency increased the probability of developing SVD. Our study raises the importance that vitamin D supplementation combined with monitoring hypertension are promising approaches in the management of SVD.
