Molecular mechanisms responsible for the impact of antiepileptic therapy on bone mineral density of epileptic patients

Abstract: 59В настоящее время в мировой эпилептологии накоп-лен научный материал, позволяющий поднять серьезную проблему влияния противоэпилептической терапии на ми-неральную плотность кости (МПК): отмечено, что пациен-ты с эпилепсией подвержены значительно более высокому риску возникновения переломов по сравнению с общей по-пуляцией [1][2][3], а частота развития остеопороза (ОП) у дан-ной категории больных в 1,7 раза выше по сравнению с об-щепопуляционной [4]. Данные изменения связывают с дли-тельным применением против… Show more

“…Possible mechanisms of anticonvulsant-induced osteoporosis currently include: 1) hepatic cytochrome P450 induction leading to increased vitamin D catabolism and decreased blood content of its bioactive metabolites; 2) decreased effect on bone tissue of endogenous parathyroid hormone with development of secondary hyperparathyroidism; calcitonin deficiency; 3) direct effect of anticonvulsants on the activity of osteoblasts and osteoclasts; 4) inhibition of vitamin K metabolism (phenytoin); 5) suppression of phosphate reabsorption in renal tubules [8,21].…”

“…This is important because often BMD changes in this patient group remain subclinical for long periods of time and may take years to manifest clinically. Older generation anticonvulsants such as barbituates, benzodiazepines, valproic acid, and carbamazepine have been identified as a separate risk factor for drug-induced osteoporosis, but there are no similar reports for newer generation antiepileptic drugs [21]. In addition, the assessment of cumulative risk of drug-induced osteoporosis in patients with epilepsy is still difficult in clinical practice, as there are no algorithms to identify patients at high risk of drug-induced osteoporosis caused by anticonvulsants.…”
