OBJECTIVE: Patients treated with carbamazepine (CBZ) have increased serum levels of total cholesterol (TC), high-density lipoproteins (HDL), and low-density lipoproteins (LDL). We aimed to investigate whether these changes of serum lipids are reversible after CBZ withdrawal. MATERIAL AND METHODS: We used a prospective, randomized double-blinded design. A total of 160 patients who had been seizure free on anti-epileptic drug monotherapy for more than 2 years were included and randomized to withdrawal or not...

OBJECTIVE: To characterize the association between commonly used anti-epileptic drugs (AEDs) and plasma lipid levels in patients with epilepsy. METHODS: We sought observational studies that reported association between commonly used AEDs and plasma lipid levels in patients. The primary outcome was low-density lipoprotein (LDL) cholesterol. High-density lipoprotein (HDL), total cholesterol and triglyceride were secondary outcomes. The control group included healthy controls, pre-treatment patients or patients treated with other AEDs...

INTRODUCTION: Several studies have reported that commonly used antiepileptic drugs like phenytoin, and carbamazepine increase serum High Density Lipoproteins Cholesterol (HDL-C) levels, while some others documented no such effect. Further, some researchers also observed that valproic acid and other newer antiepileptic drugs like lamotrigine and levetiracetam has no influence on serum lipid profile. The present study was planned to assess and compare serum lipid profile of young adult patients on commonly used antiepileptic drugs (phenytoin, oxcarbazepine and valproic acid) and newer antiepileptic drug (levetiracetam) attending Neurology OPD of a tertiary care hospital in Puducherry, India compared to normal subjects...

BACKGROUND AND PURPOSE: The most common prescribed antiepileptic drugs (AEDs), phenytoin and valproate, are potent enzyme inducers and inhibitors of the cytochrome P450 system, which interfere with lipid profile and glucose homeostasis. Studies on this topic have suffered from inadequate assessment of confounders and have rarely included glucose homeostasis and lipid profile as well as both enzyme inducers and inhibitors in the same study. We sought to determine whether these drugs had an effect on lipid profile and glucose homeostasis in Thai epileptic patients...

PURPOSE: We previously demonstrated that converting patients from the enzyme-inducers phenytoin or carbamazepine to the non-inducers levetiracetam or lamotrigine reduces serum lipids and C-reactive protein (CRP). We sought to determine if the same changes would occur when patients were switched to topiramate, which has shown some evidence of enzyme induction at high doses. We also examined the effects of drug switch on low-density lipoprotein (LDL) particle concentration. METHODS: We converted 13 patients from phenytoin or carbamazepine monotherapy to topiramate monotherapy (most at doses of 100-150 mg/day)...

We conducted a case control study to evaluate the effect of phenytoin and valproic acid on serum lipids and liver function tests in epileptic children. Seventy-nine children receiving at least 6 months of antiepileptic monotherapy were categorized into two groups, depending on whether they were receiving phenytoin or valproic acid. Age matched healthy controls were also included. The mean total cholesterol (TC) in children on phenytoin therapy was significantly higher than the control group (P=0.03). Serum triglycerides, low density lipoprotein cholesterol, very low density lipoprotein cholesterol, and high density lipoprotein cholesterol, were not significantly different in the three groups...

The effect of enzyme-inducing anticonvulsant drugs on the serum concentrations of lipoproteins has been widely studied. However, there is little agreement between the results with regard to the possible development of a lipoprotein profile related to an increased or decreased cardiovascular risk. It has been suggested that cholinesterase (ChE) could be induced by these drugs, something of undeniable interest as ChE appears to have a relation to the metabolism of lipoproteins. The serum activity of ChE was determined in a group of 90 adult epileptic patients (56 male and 34 female) treated with phenobarbital, phenytoin, and carbamazepine...

Phenytoin (PHT) increases high density lipoprotein cholesterol (HDL-C) and reduces coronary artery disease mortality in humans. We report the results of PHT treatment on atherosclerosis susceptibility and lipid profile in four different types of mouse: control C57BL/6 mice and cholesteryl ester transfer protein transgenic mice as models of fatty streak, and LDL receptor-deficient mice and apolipoprotein E-deficient mice as models of mature atherosclerosis. Each mouse type was fed an appropriate diet to induce atherosclerosis and prevent liver toxicity...

INTRODUCTION: It is known that anticonvulsants are able to modify lipid profile; nevertheless the initial studies were performed in patients or polytherapy whereas later investigations were carried out mostly in children. OBJECTIVES: To evaluate serum lipids, lipoproteins and apolipoproteins in adult epileptic patients on monotherapy. MATERIAL AND METHODS: Total cholesterol, triglycerides, low- and high-density lipoprotein cholesterol (including the HDL2 and the HDL3 subfractions) and apolipoproteins A1 and B were measured in 120 epileptics patients treated with carbamazepine (n = 42), sodium valproate (n = 38) and phenytoin (n = 40) and compared with the values of 48 healthy subjects...

Observational studies have demonstrated a positive association between phenytoin use and HDL cholesterol (HDL-C). Our goal was to determine whether phenytoin raises HDL-C in nonepileptic subjects at risk for coronary artery disease. We performed a double-blind, placebo-controlled, parallel-group study in 41 subjects with reduced levels of HDL-C. Subjects were placed on an American Heart Association Step I diet and were randomized to receive either phenytoin or placebo for 3 months. Serum levels of phenytoin were monitored and adjusted to between 7...

Total cholesterol, free cholesterol, HDL cholesterol, LDL cholesterol and triglycerides have been assayed in serum of 42 epileptic patients in chronic therapy (21 in monotherapy and 21 in polytherapy) in comparison with 21 normal controls. Free cholesterol showed an highly significant increase in epileptics, in whom triglycerides appeared very reduced. In contrast to previous reports of a large increase of HDL cholesterol in phenitoin treated patients, only a not significant increase was found. The other parameters appeared unchanged...

Serum high density lipoprotein (HDL) cholesterol and other lipoproteins were measured in 27 TIA-patients with a mean age of 49 +/- 10 years before and during phenytoin therapy. The pretreatment concentrations of HDL-cholesterol (mmol/l, mean +/- SD) were lower (p less than 0.001) in male (1.03 +/- 0.25) and in female patients (1.15 +/- 0.44) than in healthy male (1.28 +/- 0.34) and female controls (1.52 +/- 0.31) respectively. After one month's phenytoin therapy HDL cholesterol concentrations reached normal levels (men 1...

From the 10 North American study populations of the Lipid Research Clinics Program, mean levels of plasma high-density (HDL) cholesterol were contrasted between users of eight categories of prescribed medications and a control group of nonusers of those categories matched for age, sex, study population and ponderosity. Women taking propranolol had a mean HDL cholesterol level 12 mg/dl lower than nonusers (p < 0.05). Men taking phenytoin had a mean HDL cholesterol level more than 18 mg/dl higher than nonusers (p < 0...

Serum low-density lipoprotein cholesterol and high-density lipoprotein cholesterol concentration and the ratio between them, major risk factors of coronary heart disease, and liver size were investigated in 18 subjects who were on enzyme-inducing anticonvulsants, phenytoin alone or in combination with phenobarbital and/or carbamazepine. The subjects with a high liver cytochrome P-450, indicating hepatic microsomal enzyme induction, who showed an increase in liver size, had an elevated high-density lipoprotein concentration and high-density lipoprotein cholesterol/total cholesterol ratio, and a reduced low/high-density lipoprotein cholesterol ratio...

The in vitro plasma protein binding of phenytoin (diphenylhydantoin), salicylic acid, propranolol, pethidine (meperidine) and chlorpromazine was measured using an air-driven, bench-top ultracentrifuge and the results were compared with those obtained by equilibrium dialysis. For all drugs studied, except chlorpromazine, a significant correlation was found between the plasma binding results obtained by the two methods. However, only in the case of propranolol the actual binding values obtained by the two techniques were very similar...

REVIEW
P V Luoma
The liver is the principal site for the synthesis and elimination of lipoproteins circulating in plasma, and alterations in hepatic function influence plasma lipoprotein levels. High HDL-C/T-C and apo A-I/apo B ratios, which are characteristic of a low coronary risk, have been typical of healthy subjects with high microsomal enzyme activity in the liver. Microsomal enzyme inducing drugs such as phenytoin, phenobarbital and carbamazepine, and also alcohol, influence serum lipid and apoprotein concentrations...
