Evaluation of Phosphorus–Calcium Homeostasis Parameters in Young People with Various Serum Levels of 25(OH)D Living in the Arctic Region

详细

The parameters of phosphorus–calcium metabolism at different levels of 25 (OH)D in young people have been studied. The studied population included 48 young men and 126 young women aged 18 to 20 years. Normal values of vitamin D were found in 40 subjects (23%); the blood level of 25-OH vitamin D was shown to be 20–30 ng/mL in 59 subjects (34%), 10–19 ng/mL in 56 subjects (32%), and <10 ng/mL in 19 subjects (11%). The calcium level proved to be associated with the rate of vitamin D deficiency. The level of parathyroid hormone was not elevated in 75% of the subjects with vitamin D deficiency. There is no correlation between PTH levels and vitamin D levels. The results show the necessity of further studies to find out the causes of insufficient response of parathyroid hormone to vitamin D deficiency.
