We studied serum calcium, phosphorus, alkaline phosphatase (ALP), thyroid hormones (total thyroxine [TT4], free thyroxine [FT4], thyroid-stimulating hormone [TSH]), parathyroid hormone (PH), and osteocalcine levels in children with epilepsy who had been receiving long-term carbamazepine (CBZ) therapy to determine whether there was any effect of CBZ therapy on these hormones. The study included 18 patients with epilepsy receiving CBZ and 16 healthy age-matched controls. The age ranged from 4-18 years (11.26 +/- 3.59 years) and 4.5-17 years (11.16 +/- 3.13 years) in the study and control group, respectively. The duration of CBZ use was between 10 months-5 years (3.12 +/- 1.09 years). When comparing the results we did not find any significant difference in serum calcium, phosphorus, ALP, osteocalcine and TSH and PH levels between the groups (p.05). However, serum TT4 and FT4 levels were found to be significantly lower in the study group than those of control group (p.05). However, we observed no clinical signs of hypothyroidism in all subjects. To these findings we suggest that serum thyroid hormone levels should be monitored in children receiving long-term CBZ therapy. |
