[Show abstract][Hide abstract] ABSTRACT: Weight gain is a common side effect of valproate (VPA) treatment, although the mechanism is not clear. Abnormal weight gain and obesity are associated with dyslipidemia, hypertension, and atherosclerosis. Measurement of the common carotid artery intima media thickness (CAIMT) gives a picture of early arterial wall alterations and, currently, is considered a noninvasive marker of premature atherosclerosis. The aim of the present study was to evaluate plasma insulin, leptin, neuropeptide Y (NPY), ghrelin, and adiponectin levels in children with epilepsy treated with VPA and to evaluate these parameters for early atherosclerosis.
Twenty prepubertal children with idiopathic epilepsy treated with VPA were enrolled in this study. Body mass index (BMI) and fasting insulin glucose ratio (FIGR) were calculated, and the plasma insulin, leptin, NPY, ghrelin, and adiponectin levels; the lipid profiles; and CAIMT were measured for all subjects before the treatment and after a follow-up period of 6 and 12 months.
When pretreatment values were compared with those at the end of 6 and 12 months, the mean BMI values, plasma insulin, leptin, NPY levels, and FIGR were increased, whereas the plasma ghrelin and adiponectin levels, lipid profiles, and CAIMT did not change significantly at the end of 6 and 12 months.
These results suggest that weight gain during VPA treatment may be related to increases in insulin, leptin, and NPY levels. Additionally, in this study, no increase in the risk for early atherosclerosis was determined by CAIMT in children with epilepsy treated with VPA.
