The aim of this study was to evaluate the effects of valproate (VPA), lamotrigine (LTG), and levetiracetam (LEV) on bone turnover and bone mineral density (BMD) in newly diagnosed adult patients with epilepsy.
Eligible adult patients who were newly diagnosed with epilepsy were treated with VPA, LTG, and LEV. The chemical indicators of bone metabolism and BMD were measured before treatment and 2 years after treatment with different antiseizure medication (ASM) monotherapies. Then, the differences in these parameters before and after treatment were analyzed.
One hundred twenty-four patients completed the 2 years follow-up; 43 received monotherapy with VPA, 32 received LTG, and 49 received LEV. Serum parathyroid hormone (PTH), bone alkaline phosphatase (B-ALP), and β-cross-linked C-telopeptide of type I collagen (β-CTX) levels were elevated in adult patients after 2 years of VPA administration; the serum procollagen I intact N-terminal peptide (PINP) level was noticeably higher in patients after LEV treatment than before treatment. Meanwhile, the BMD of the lumbar spine and femoral neck did not change in patients treated with VPA, LTG, and LEV.
Valproate altered bone turnover in adult patients with epilepsy, while LTG and LEV did not exert harmful effects on bone health in adult patients.
