Abstract

The relationship between delayed hypersensitivity and serum levels of 25-hydroxyvitamin D were examined in sixty-three elderly people. After intracutaneous injection of five recall antigens (Candida, mumps, PPD, tricophyton and varidase) nineteen subjects showed no response (anergy), seven showed only a weak reaction (relative anergy), and thirty-seven a normal reaction. In the anergic group mean serum level of 25-hydroxyvitamin D was significantly lower than in the group with normal immunoreactivity. Five subjects with anergy and serum 25-hydroxyvitamin D below 20 nmol/l were treated with oral vitamin D or UV irradiation for two to three months, after which both the serum 25-hydroxyvitamin D levels and the delayed hypersensitivity were normalized. In a non-treated group anergy persisted in seven out of nine patients in a second skin test. We conclude that anergy in the delayed hypersensitivity skin test in humans may in some cases be due to vitamin D deficiency.

Relationship between vitamin D metabolites and bone mineral density in young males: a cross-sectional and longitudinal study.

The purpose of this study was to investigate the association between vitamin D analogs and peak bone mineral density (BMD, g/cm(2)) in young men. The cohort consisted of 78 healthy young males with a mean age of 22.6 years at baseline. BMD of the total body, hip, and spine and lean body mass were measured at baseline and at follow-up 2 years later. Blood samples were assayed for 25-hydroxyvitamin D(2) (25OHD(2)), 25-hydroxyvitamin D(3) (25OHD(3)), and 25-hydroxyvitamin D (25OHD) at baseline using high-performance liquid chromatography. Levels of 25OHD(3) significantly correlated to BMD at all sites and to lean body mass (r = 0.23-0.35, P < 0.05). In contrast, levels of 25OHD(2) significantly negatively correlated with BMD of the total body (r = -0.28, P = 0.01) and spine (r = -0.27, P = 0.02). BMD was then adjusted for the influence of age, body weight, body height, and physical activity (hours/week). Level of 25OHD(3) was then found to be an independent predictor of BMD of the total body (beta = 0.24, P = 0.03) and spine (beta = 0.25, P = 0.03), while level of 25OHD(2) was an independent negative predictor at the same sites (beta = -0.23 for both, P = 0.03). There was a negative association between levels of 25OHD(3) and 25OHD(2) (r = -0.31, P = 0.006). In summary, our novel results suggest an inverse relationship between 25OHD(3) and 25OHD(2) and an opposite relationship of these vitamin D analogs to BMD in young men.

C-3 epimers can account for a significant proportion of total circulating 25-hydroxyvitamin D in infants, complicating accurate measurement and interpretation of vitamin D status.

CONTEXT: We have recently introduced liquid chromatography-tandem mass spectrometry (LC-MS/MS) for 25-hydroxyvitamin D(2) (25OHD(2)) and 25OHD(3) testing. During subsequent clinical use, we identified significantly elevated results in some infants. We hypothesized this might represent assay interference caused by C-3 epimers of 25OHD(2) or 25OHD(3). OBJECTIVE: Our aims were to 1) determine the prevalence of C-3 epimers of 25OHD(2) or 25OHD(3) in human serum, and 2) identify the patient populations that might be affected. STUDY DESIGN: We modified our LC-MS/MS method to allow detection of C-3 epimers. We retested specimens from four patient groups with the new method and an extracted RIA: 1) children less than 1 yr old, 2) children 1-18 yr old, 3) adults aged 20-87 yr with liver disease, and 4) adults aged 19-91 yr without liver disease. RESULTS: In 172 children from group 1 with detectable 25OHD(2) or 25OHD(3), we identified C-3 epimers in 39 (22.7%). The epimers contributed 8.7-61.1% of the total 25-OHD. There was an inverse relationship between patient age and epimer percentage (r = 0.48; P < 0.002). The RIA gave accurate 25-OHD results that correlated with the modified LC-MS/MS method. No C-3 epimers were detected in any of the other groups. CONCLUSIONS: Significant concentrations of C-3 epimers of 25OHD(2) or 25OHD(3) are commonly found in infants. This can lead to overestimation of 25-OHD levels. Measurements in children less than 1 yr should therefore be performed with an assay that allows accurate detection of 25-OHD in the presence of its C-3 epimers.

Correlations between bone mineral density and demographic, lifestyle, and biochemical variables in community-dwelling Japanese women 69 years of age and over.

INTRODUCTION: A few epidemiologic studies have comprehensively attempted to identify risk factors for low bone mineral density (BMD) in elderly Asian women. The purpose of this study was to identify demographic, lifestyle, and biochemical factors correlated with BMD in elderly Japanese women 69 years of age and over. METHODS: The study design was cross-sectional. The subjects were 583 ambulatory women aged 69 years and over, and their average age was 74.3 (SD 4.4) years. Predictor variables were age, reproductive history, anthropometric indices, grip strength, calcium intake, lifestyle information, and serum 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D (1,25(OH)(2)D), osteocalcin (OC), and undercarboxylated osteocalcin (ucOC) values. The outcome variable was forearm BMD measured with a DTX-200 osteometer. RESULTS: Simple linear regression analyses showed that BMD was significantly positively associated with body height, weight, body mass index, grip strength, serum albumin concentration, and "housework," and negatively associated with age, years since menopause, age at menarche, number of children, serum 1,25(OH)(2)D concentration, serum OC concentration, and ucOC concentration. The stepwise multiple regression analysis showed that weight (beta=0.00316, SE=0.00028, R(2)=0.180), age (beta=-0.00321, SE=0.00050, R(2)=0.108), log-transformed serum OC (beta=-0.0445, SE=0.0064, R(2)=0.053), log-transformed serum 1,25(OH)(2)D (beta=-0.0401, SE=0.0074, R(2)=0.050), "farmwork" (beta=0.00904, SE=0.00426, R(2)=0.005), and serum 25(OH)D concentration (beta=0.000281, SE=0.000120, R(2)=0.003) were significantly associated with BMD. CONCLUSION: It was concluded that body weight is a major predictor of forearm BMD among the factors measured in this study in independent Japanese women 69 years of age and over and that serum 1,25(OH)(2)D concentration may be associated with cortical BMD. Maintenance of body weight is very important for maintaining BMD in this population, unless a large weight aggravates obesity-related diseases. A follow-up study is needed to confirm these findings.
