Background and Purpose Long-term treatment with some older antiepileptic drugs may lead to hyperhomocysteinemia. Levetiracetam (LEV) is a newer broad-spectrum antiepileptic agent whose effects on homocysteine concentrations remain unclear. The purpose of this study was to prospectively determine the short-term and long-term effects of LEV monotherapy on homocysteine metabolism in children with epilepsy. Methods The study population consisted of 32 children [18 females, 14 males; age 5.94±4.10 years (mean±SD), age range 1–15 years] who received LEV monotherapy for new-onset epilepsy. Serum folate, serum vitamin B12, and plasma total homocysteine (p-tHcy) were measured before and at 2 months (n=32), 6 months (n=25), and 12 months (n=18) of LEV monotherapy. Results p-tHcy was significantly decreased at 2 months of treatment (p=0.031). Furthermore, analysis of covariance showed statistically significant decreases in p-tHcy at 2 months (p=0.013) and 6 months (p=0.015) of LEV treatment after controlling for age, sex, body mass index, and LEV dose. There were no significant alterations in the other parameters during the study. The drug doses were 18.1±7.1, 20.1±9.2, and 21.2±11.8 mg/kg at 2, 6, and 12 months of LEV treatment, respectively. Conclusions In contrast with older antiepileptic drugs, long-term LEV monotherapy in children with epilepsy does not cause adverse alterations on homocysteine metabolism. Larger prospective studies are needed to definitively clarify whether LEV may be considered a safer alternative drug for preventing antiepileptic-drug-induced cardiovascular complications in adult life.

Background and Purpose The high prevalence of antiphospholipid antibodies (aPL) and antinuclear antibodies (ANA) in patients with epilepsy may be associated with either the disease itself or the antiepileptic treatment. The purpose of this prospective study was to determine the prevalence of aPL and ANA in children with idiopathic epilepsy before and during treatment with antiepileptic drugs. Methods aPL, including both anticardiolipin and anti-β2-glycoprotein I antibodies, and ANA statuses were determined in 40 healthy children, 30 children treated with sodium valproate (VPA) monotherapy, and 20 children treated with carbamazepine (CBZ) monotherapy before and at 6, 12, and 24 months after treatment initiation. Results Fifteen children (50%) in the VPA-treated group and 7 (35%) in the CBZ-treated group showed positivity for aPL before treatment initiation, compared with only 4 of the 40 controls. Nine children (30%) in the VPA-treated group and 4 (20%) in the CBZ-treated group showed positivity for ANA before treatment initiation, compared with only 2 of the 40 controls. The subgroup analysis found nonsignificant associations at the different time points regarding the positivity of all of the autoantibodies. Only patients treated with VPA had a significantly decreased risk of aPL positivity after 6 months of treatment. Conclusions The increased prevalence of autoantibodies in children with idiopathic epilepsy is strongly associated with the disease itself.
