Am J Clin Pathol 2012;137:831-835 833 © American Society for Clinical Pathology The Author’s Reply I read with interest the comments by Arya and Agarwal who broadened the discussion of vitamin D testing into an international context and raised a number of important points. First, 25-hydroxyvitamin D testing is currently not accessible in many parts of the world owing to financial constraints or...
Here, we aim to investigate the independent and combined associations of serum 25-hydroxyvitamin D (25(OH)D) and cardiorespiratory fitness (CRF) with glucose metabolism. Fasting blood samples of 107 men aged 40-79 years were analyzed for 25(OH)D, glucose, insulin, glycated hemoglobin, and lipid profile. Homeostasis model assessment of insulin resistance index (HOMA-IR) was calculated from the f...
BACKGROUND Studies suggest that vitamin D status may be associated with prostate cancer risk although the direction and strength of this association differs between experimental and observational studies. Genome-wide association studies have identified genetic variants associated with 25-hydroxyvitamin D [25(OH)D] status. We examined prostate cancer risk in relation to single-nucleotide polymor...
Objective. To investigate the relationship between serum 25-hydroxyvitamin D3 [25(OH)D3] levels and carotid intima-media thickness (IMT) as well as carotid atherosclerotic plaque in patients with type 2 diabetes mellitus (T2DM). Methods. 314 patients with T2DM were enrolled in this study. The clinical data and laboratory examinations of subjects were recorded, such as serum 25(OH)D3, hemoglobin...
Our previous study provided evidence that higher serum levels of the active form of vitamin D, 1,25-dihydroxyvitamin D (1, 25-D), might possibly slow the progression of subclinical to clinically significant prostate cancer in both black and white men, especially after age 57. This paper extends the prior study by contrasting seasonal variation in 1,25-D and its precursor, 25-hydroxyvitamin D (2...
I t has been suggested that vitamin D reduces the risk of type 2 diabetes. The finding that vitamin D deficiency is associated with impaired -cell function and insulin resistance in animals (1,2) and humans (3,4) is in line with that hypothesis. In the only cohort study publ i shed , the in take of v i t amin D supplements was inversely associated with the development of type 2 diabetes (5). Si...
OBJECTIVES The study sought to determine the link between vitamin D concentrations and incident hypertension in prospective study and meta-analysis. METHODS The study was embedded in the Kailuan Study, a population-based cohort of adults that contains underground miners. In 2012, we studied 2,456 men and women free of prevalent hypertension, age 21 to 67 at baseline. Serum 25-hydroxyvitamin D...
An international 19-laboratory survey was organized to compare assays for 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, and 1,25-dihydroxyvitamin D in plasma. Each participant received two ethanolic standard solutions of each metabolite and eight plasma samples. Each laboratory used its usual procedures. Mean interlaboratory coefficients of variation (CVs) for the eight plasma samples were 35%...
Pancreatic cancer is a malignancy of poor prognosis which is mostly diagnosed at advanced stages. Current treatment modalities are very limited creating great interest for novel preventive and therapeutic options. Vitamin D seems to have a protective effect against pancreatic cancer by participating in numerous proapoptotic, antiangiogenic, anti-inflammatory, prodifferentiating, and immunomodul...
BACKGROUND Plasma 25-hydroxyvitamin D (25(OH) D) deficiencies are associated with several diseases. The magnitude of systemic inflammatory response, as evidenced by C-reactive protein (CRP), is a major factor associated with lower 25(OH)D. Other aspects of the systemic inflammatory response may be important in determining plasma 25 (OH)D concentrations. AIM To examine the relationship between...
