Özet

It is still not completely clear whether carbamazepine causes alterations in vitamin D status and in bone metabolism. The objective of this study was to investigate the effects of carbamazepine on serum levels of 25-hydroxyvitamin D and on biomarkers of bone formation and resorption in healthy rats. Levels of calcium, 25- hydroxyvitamin D, parathormone, C-telopeptide, bone specific alkaline phosphatase and osteocalcin were measured in 3 groups of rats consisting of controls (n=10), isotonic saline solution group (n=10) and carbamazepine group (n=10). Mean calcium levels were found to be significantly lower in healthy controls in comparison to isotonic saline solution and carbamazepine groups (10.0+/-4, 10.81+/-0.16, 10.93+/-0.22 mg/dL, respectively, p<0.05). Mean levels of 25- hydroxyvitamin D, were found to be significantly higher in control group compared to isotonic saline solution group (25- hydroxyvitamin D; 25.91+/-1.12, 19.99+/-0.99 ng/mL, respectively, p<0.01.). Mean levels of parathormone and osteocalcin were found to be significantly higher in control group compared to isotonic saline solution group and carbamazepine group. Parathormone levels were measured as 3.46+/-0.83, 1.08+/-0.08, 0.94+/-0.02 pg/mL, respectively (p<0.01). Osteocalcine levels were measured as 1.66+/-0.001, 1.32+/-0.002, 1.32+/-0.001 ng/mL, respectively (p<0.001). A significant difference in terms of mean serum bone specific alkaline phosphatase and C-telopeptide levels among groups was not observed. The main outcome of this prospective study in healthy rats showed no change in biochemical parameters of bone turnover during treatment with carbamazepine.
