The Mutual Interplay between Bone, Glucose and Lipid Metabolism: The Role of Vitamin D and PTH
Abstract
Background. We sought to investigate the mutual interplay between bone, glucose and lipid metabolism in a wide cohort of community-based subjects. Methods. We studied 1240 blood donors (F/M ratio 1/3.2, mean age 41.9 ± 11.7 SD). Serum ionized (Ca++), magnesium (Mg++), 25-hydroxy-vitamin D [25(OH)D], PTH-1-84, 1,25-dihydroxyvitamin D [1,25(OH)2D], total cholesterol (C), HDL-C, triglycerides and glucose were measured and LDL-C levels were calculated in all subjects. Results. 25(OH)D negatively correlated with BMI (R = −0.11), PTH (R = −0.16) (p p p 2D (R = 0.12) and creatinine (R = 0.17) (p p p p p p p p p p = 0.05), while the odds of showing abnormal LDL-C levels increased in association with elevated PTH (p < 0.01). Conclusion. Vitamin D, PTH, glucose and lipid metabolism are mutually influenced. Hypovitaminosis D predisposes toward worsening lipid profiles through the actions of PTH, while serum PTH levels per se associate with higher glucose and LDL-C levels.
