25-hydroxyvitamin DCardiovascular diseaseVitamin D deficiencyVitamin D (25-OH-D3) deficiency is an emerging global health problem. Chronic kidney disease (CKD) patients have a higher risk of this deficiency. We aimed to determine the prevalence of 25-OH-D3 deficiency in a cohort of CKD ...
En México, la ingesta diaria sugerida de vitamina D es de 5.6 μg/día (224 UI), que resulta significativamente menor a las recomendaciones en los Estados Unidos y Europa (entre 400 y 1,000 UI). Debido al aumento en la deficiencia de vitamina D en los últimos años y a la...
Despite this evidence, there are scarce data regarding the concentration of 25(OH)D and its metabolites among older adults with physical disability. Methods: the National Health and Nutrition Examination Survey 2007-2014 data were collected to compare 25(OH)D3, 25(H)D2, and total 25...
3) conversion of 25(OH)D3 by the kidney (functioning as an endocrine gland) to the hormone 1,25-dihydroxyvitamin D3 [1,25(OH)2D3 ]; 4) systemic transport of the dihydroxylated metabolite 1,25(OH)2D3 to distal target organs; and 5) binding of 1,25(OH)2D3 to a nuclear recepto...
The complete random design used was in factorial 3X3, with three strains (Ross 308, Cobb 500 and Hybro) and three inclusion levels of vitamin D3 (1250 IU vitamin D3; 3000 IU vitamin D3 and 2760 UI of 25- hydroxycholecalciferol (OH) D3), provi...
Vitamin D values below 25 ng/mL are related to an increase in vascular tone mediated by smooth muscle contraction. Furthermore, it can produce direct effects on vascular smooth muscle cells, RAAS over-regulation, modulation of calcium metabolism, and secondary hyperparathyroidism. All this ...
Figura 1. Metabolismo de la vitamina D (panel A) y estructura de la vitamina D activada (calcitriol o 1,25-dihidroxicolecalciferol; C27H44O3) (panel B). Panel A. Metabolismo de la vitamina D. La vitamina D puede adquirirse a través de la dieta, o bien por la conversión cutánea...
calcio y VD se puede obtener con la medida de la concentración de PTH, aunque el mejor indicador se considera la concentración de 25-hidroxivitamina D (25-OH VD) sérica, ya que no es regulada y refleja la ingesta dietética de vitamina D2 o D3 y la síntesis cutánea de D3....
Patients with inadequate serum levels of 25OHD 3 had non-significant lower BMD, both at the LS and the FN. Prevalence of inadequate serum levels of 25-(OH)D was high in our series. A no statistically-significant tendency towards low BMD in patients with inadequate serum levels of 25-(OH...
To analyze lipid changes and their relationship with 25-hydroxy vitamin D3 (25-OH-D) levels in patients under 18 years old with type 1 diabetes mellitus (T1DM). A cross-sectional, descriptive study. Patients under 18 years with T1DM were enrolled by consecutive, nonrandomized sampling. Data ...
