ABSTRACT
 
Objectives: To compare the long-term effects of carbamazepine (CBZ), valproic acid (VPA), and lamotrigine (LTG) as monotherapy on the markers of vascular risk.
 
Methods: The present cross-sectional study was carried out at the Department of Neurology, Jinnah Postgraduate Medical Centre (JPMC), Karachi, Pakistan, from 2012 to 2013. We selected 120 adult patients with epilepsy and 40 control subjects. The patients with epilepsy were divided into 3 groups according to the use of antiepileptic drugs (AEDs) (CBZ, n = 40; VPA, n = 40; and LTG, n = 40). All participants` total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), very low-density lipoprotein cholesterol (VLDL-c), high-density lipoprotein cholesterol (HDL-c), ratio of TC/HDL-c, ratio of LDL-c/HDL-c, body mass index (BMI), and blood pressure was determined.
 
Results: In patients with epilepsy, CBZ and VPA treatment caused a noteworthy increase in the concentrations of TG, TC, and LDL-c compared with LTG treatment and the control group (p<0.001). The HDL-c significantly decreased in CBZ, VPA, and LTG-treated patients as compared with controls (p<0.001). The ratio of LDL-c/HDL-c and TC/HDL-c significantly increased in VPA- and CBZ-treated groups compared with the LTG-treated, and control group, while the ratio was also considerably elevated in patients treated with CBZ as compared with the patients treated with VPA. The weight and BMI of the patients treated with AEDs were higher (p<0.01).
 
Conclusions: Patients with epilepsy on CBZ or VPA have changed vascular risk markers that may lead to atherosclerosis, while LTG-treated patients have less alteration in lipid profile.
