A significant bias was found when using the Siemens ADVIA Centaur XP system for measurement of 25-hydroxyvitamin D (25OHD) with VACUETTE® tubes with Serum Clot Activator and Gel. Here, we examined whether other commonly used tubes or temperatures affected 25OHD results obtained with the Siemens ADVIA Centaur XP system. Serum was collected into five types of vacuum blood collection tubes from th...
We enrolled 23 Japanese men (age: 76.0 ± 8.7) and 17 women (age: 78.3 ± 9.3) in this study. The physical function of even a person getting on a wheelchair could be tested in all subjects. Blood was collected by venipuncture and the serum 1, 25-hydroxy vitamin D (1, 25OHD) concentration was measured. The Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment-Japanese version ...
Success of Standard Dose Vitamin D Supplementation in Treated Human Immunodeficiency Virus Infection
Background. Vitamin D insufficiency is prevalent in human immunodeficiency virus-positive (HIV+) persons. Human immunodeficiency virus and antiretroviral therapy (ART) may create unique risk factors, and the optimal vitamin D repletion and maintenance regimen in HIV+ persons remains unclear. Methods. Human immunodeficiency virus-positive adults on suppressive ART underwent routine serum 25-hy...
We correlated serum 25-hydroxyvitamin D(3) (25OHD) levels with tumor characteristics and clinical disease outcome in breast cancer patients and assessed the impact of genetic determinants of vitamin D insufficiency. We collected serum from 1800 early breast cancer patients at diagnosis, measured 25OHD by radioimmunoassay (RIA), and determined genetic variants in vitamin D-related genes by Seque...
OBJECTIVE Circulating levels of 25-hydroxyvitamin D (25OHD) are positively associated with high density lipoprotein (HDL) cholesterol. We sought to replicate a previously reported interaction between APOA5 genotype and vitamin D, and to examine whether HDL-associated genetic loci modify the association between serum 25OHD and HDL cholesterol. METHODS We examined whether 42 single nucleotide p...
Advances in Vitamin D nutritional physiology since publication of the DRIs in 1997 are briefly summarized. Available data indicate that (1) Vitamin D's canonical function, optimizing intestinal calcium absorption, is fully expressed at serum 25-hydroxyvitamin D (25OHD) concentration of approximately 80nmol/L; (2) elevated parathyroid activity, typical of aging populations, is minimized at the s...
Vitamin D is one of the essential nutrients to sustain the human health. As a member of the steroid hormone family, it has a classic role in regulating metabolism of calcium and a non-classic role in affecting cell proliferation and differentiation. Epidemiological studies have shown that 25OHD deficiency is closely associated with common chronic diseases such as bone metabolic disorders, tumor...
OBJECTIVES This study aimed to assess the effect of 25-hydroxyvitamin D3 (25OHD) which is a hydroxide of vitamin D3 ingestion on upper respiratory tract infection (URTI). DESIGN AND SETTING A prospective, randomized, double-blind, placebo-controlled study was performed from December 2015 to September 2016 in the Nihonbashi Egawa Clinic, Kei Medical Office TOC Building Medical Clinic, and Medi...
OBJECTIVE Obtaining adequate vitamin D during pregnancy is important for the health of mother and child. Low circulating 25-hydroxyvitamin D (25OHD) concentrations, a measure of vitamin D status, have been reported in pregnant women in several countries; yet, there are few studies of pregnant Canadian women. We measured 25OHD concentrations in a multi-ethnic group of pregnant women living in Va...
Cystic fibrosis (CF) is the most common genetic respiratory disease in the west, which is due to a malfunction in protein of cystic fibrosis transmembrane regulator (CFTR). Since some studies showed the effect of vitamin D supplementation and increment in 25OHD serum level in these patients, this study aimed to conduct a review in this scope. For reaching the available studies, a search was con...
