Abstract
The first objective of this study was to identify if soluble tumor necrosis factor-receptor 1 (sTNFr1) and -receptor 2 (sTNFr2) are modulated by vitamin D status (insufficient vs. sufficient). The second objective was to reveal if soluble TNF receptors fluctuate with serum 25-hydroxyvitamin D (25(OH)D) concentrations following a bolus of supplemental vitamin D. Reportedly healthy male adults were randomly (double-blind) assigned to a placebo (n=15) or vitamin D (100,000 IU of cholecalciferol; n=14) supplement. Supplements were taken as a bolus immediately after and on the same day as providing the first blood sample (baseline (Bsl)). Fasting blood samples were also obtained at 1-, 3-, 7-, and 24-d after the bolus. Serum 25(OH)D, 1,25-dihyroxyvitamin D (1,25(OH)D), tumor necrosis factor (TNF)-α, sTNFr1, and sTNFr2 were measured in each blood sample. At Bsl, subjects were classified as vitamin D insufficient (serum 25(OH)D
