Acute PTH response to oral calcium load and seasonal variation of vitamin D status in healthy young adult subjects

Article Abstract:

Parathormone (PTH) levels are related to 25-hydroxyvitamin D (25(OH)D) and the prediction of the effect of oral calcium load on absolute concentrations of PTH requires consideration of the vitamin D status of individuals. Levels of 25(OH)D and PTH show seasonal changes in young, adult and elderly people exposed to the sun. The levels of PTH and 25(OH)D however, show negative correlation before and after winter. The levels of PTH after calcium load are higher after winter than before winter due to post-winter higher basal levels of PTH.

The influence of smoking on vitamin D status and calcium metabolism

Article Abstract:

The effects of smoking on serum parathyroid hormone (PTH), serum vitamin D metabolites, serum ionized calcium, serum phosphate and biochemical markers of bone turnover were assessed in healthy Danish perimenopausal women. Smoking was found to significantly effect calcium and vitamin D metabolism. The depression of the vitamin D-PTH system observed in smokers may be a possible mechanism for the deleterious effects of smoking on the skeleton.

Vitamin D deficiency in veiled Kuwaiti women

Article Abstract:

The incidences of vitamin D deficiency and osteomalacia are high among veiled women in Kuwait due to a lack of exposure to sunlight. A study conducted on 50 veiled and 22 unveiled women between the ages of 14 and 45 indicates that the serum alkaline phosphatase is high, while plasma 25-hydroxy cholecalciferol and inorganic phosphorus is low in veiled women. Parathyroid hormone levels were also high in patients with osteomalacia.
