[Bone mineral density assessment of women on long-term antiepileptic therapy]
1Tashkent Medical Academy, Tashkent, Uzbekistan.
Objective:
To study the effect of anticonvulsants on bone mineral density in patients with epilepsy.
Material And Methods:
The study included 90 women with epilepsy and a control group of 60 healthy women. The subjects' serum levels of parathyroid hormone, alkaline phosphatase, calcium, phosphorus, and vitamin D were measured. Mineral density and bone structure were assessed using dual-energy X-ray absorptiometry (DEXA).
Results:
In women with epilepsy, the serum levels of calcium, phosphorus, and vitamin D were significantly lower compared to the control group, and the levels of parathyroid hormone and alkaline phosphatase were significantly higher. There was also a statistically significant difference in the DEXA values between study groups. In women with epilepsy who received enzyme-inducing antiepileptic drugs, calcium, phosphorus, and vitamin D levels were significantly lower compared to patients who received enzyme-inhibiting antiepileptic drugs. Bone mineral density was positively correlated with serum micronutrients (calcium, phosphorus, vitamin D) and negatively with serum alkaline phosphatase and duration of therapy.
Conclusion:
Bone tissue disorders are common in patients with epilepsy. These disorders may be associated with prolonged use of antiepileptic drugs, especially enzyme inducers.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:17Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
