Abstract
Identified more than two centuries ago, cholesterol plays a pivotal role in human physiology. Since cholesterol metabolism is a physiologically significant process, it is not surprising that its alterations are associated with several pathologies. The discovery of new molecular targets or compounds able to modulate this sophisticated metabolism has been capturing the attention of research groups worldwide since many years. Endogenous and exogenous compounds are known to regulate cellular cholesterol synthesis and uptake, or reduce cholesterol absorption at the intestinal level, thereby regulating cholesterol homeostasis. However, there is a great need of new modulators and diverse new pathways have been uncovered. Here, after illustrating cholesterol metabolism and its well-known regulators, some new players of this important physiological process are also described.

Curr Probl Cardiol 2023; 48:101868. [PMID: 37295636 DOI: 10.1016/j.cpcardiol.2023.101868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Accepted: 06/04/2023] [Indexed: 06/12/2023]
Abstract
The risks of cardiovascular events (CVEs) in people with epilepsy (PWE) are not well understood. To establish the short- and long-term burden of CVEs in PWE. Electronic health records from a global federated health research network (TriNetX) were used to establish a cohort of PWE. Primary outcomes were: (1) the proportion of people experiencing a composite outcome of cardiac arrest, acute heart failure (HF), acute coronary syndrome (ACS), atrial fibrillation (AF), severe ventricular arrhythmia or all-cause death within 30 days of a seizure; and (2) the 5-year risk for a composite outcome of ischemic heart diseases, stroke, hospitalization, or all-cause death in the PWE experiencing early CVEs. Cox-regression analyses with propensity score matching was used to produce hazard ratios (HRs) and 95% confidence intervals (CI). In 271,172 PWE (mean age 50 ± 20 years; 52% females), the 30-day risk of CVEs following seizure was: 8.7% for the composite outcome, 0.9% for cardiac arrest, 0.8% for HF, 1.2% for ACS, 4.1% for AF, 0.7% for severe ventricular arrhythmias, and 1.6% for all-cause death. For the 15,120 PWE experiencing CVEs within 30 days of seizure, the 5-year adjusted risks for all composite outcomes measured were significantly increased (overall HR: 2.44, 95% CI 2.37-2.51), ischemic heart diseases HR 3.23 (95% CI 3.10-3.36), stroke HR 1.56 (95% CI 1.48-1.64), hospitalization HR 2.03 (95% CI 1.97-2.10), and all-cause death HR 2.75 (95% CI 2.61-2.89). The large proportions of PWE with active disease that experience CVEs and the poor long-term outcome associated suggest the existence of an "epilepsy-heart syndrome."

Epilepsy, antiepileptic drugs, and the risk of major cardiovascular events. Epilepsia 2021; 62:1604-1616. [PMID: 34046890 DOI: 10.1111/epi.16930] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 04/29/2021] [Accepted: 04/29/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE This study was undertaken to determine whether epilepsy and antiepileptic drugs (including enzyme-inducing and non-enzyme-inducing drugs) are associated with major cardiovascular events using population-level, routinely collected data. METHODS Using anonymized, routinely collected, health care data in Wales, UK, we performed a retrospective matched cohort study (2003-2017) of adults with epilepsy prescribed an antiepileptic drug. Controls were matched with replacement on age, gender, deprivation quintile, and year of entry into the study. Participants were followed to the end of the study for the occurrence of a major cardiovascular event, and survival models were constructed to compare the time to a major cardiovascular event (cardiac arrest, myocardial infarction, stroke, ischemic heart disease, clinically significant arrhythmia, thromboembolism, onset of heart failure, or a cardiovascular death) for individuals in the case group versus the control group. RESULTS There were 10 241 cases (mean age = 49.6 years, 52.2% male, mean follow-up = 6.1 years) matched to 35 145 controls. A total of 3180 (31.1%) cases received enzyme-inducing antiepileptic drugs, and 7061 (68.9%) received non-enzyme-inducing antiepileptic drugs. Cases had an increased risk of experiencing a major cardiovascular event compared to controls (adjusted hazard ratio = 1.58, 95% confidence interval [CI] = 1.51-1.63, p < .001). There was no notable difference in major cardiovascular events between those treated with enzyme-inducing antiepileptic drugs and those treated with non-enzyme-inducing antiepileptic drugs (adjusted hazard ratio = .95, 95% CI = .86-1.05, p = .300). SIGNIFICANCE Individuals with epilepsy prescribed antiepileptic drugs are at an increased risk of major cardiovascular events compared with population controls. Being prescribed an enzyme-inducing antiepileptic drug is not associated with a greater risk of a major cardiovascular event compared to treatment with other antiepileptic drugs. Our data emphasize the importance of cardiovascular risk management in the clinical care of people with epilepsy.

Menon S, Benova L, Mabeya H. Epilepsy management in pregnant HIV+ women in sub-Saharan Africa, clinical aspects to consider: a scoping review. BMC Med 2020; 18:341. [PMID: 33198766 PMCID: PMC7670685 DOI: 10.1186/s12916-020-01799-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 09/25/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Since the introduction of highly active antiretroviral therapy (HAART), acquired immune deficiency syndrome (AIDS) related mortality has markedly declined. As HAART is becoming increasingly available, the infection with human immunodeficiency virus (HIV+) in sub-Saharan Africa (SSA) is becoming a chronic condition. While pregnancy in HIV+ women in SSA has always been considered a challenging event for the mother and the fetus, for pregnant HIV+ women also diagnosed with epilepsy (WWE), there are additional risks as HIV increases the odds of developing seizures due to the vulnerability of the central nervous system to other infections, immune dysfunction, and overall metabolic disturbances. In light of a growing proportion of HIV+ WWE on HAART and an increasing number of pregnant women accessing mother-to-child transmission of HIV programs through provision of HAART in SSA, there is a need to develop contextualized and evidenced-based clinical strategies for the management of epilepsy in this population. In this study, we conduct a literature scoping review to identify issues that warrant consideration for clinical management. RESULT Twenty-three articles were retained after screening, which covered six overarching clinical aspects: status epilepticus (SE), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), dyslipidemia, congenital malformation (CM), chronic kidney disease (CKD), and neurological development. No studies for our population of interest were identified, highlighting the need for a cautionary approach to be employed when extrapolating findings. CONCLUSION High risks of CM and drug interactions with first-line antiepileptic drugs (AEDs) warrant measures to increase the accessibility and choices of safer second-line AEDs. To ensure evidence-based management of epilepsy within this population, the potential high prevalence of SE, CKD, dyslipidemia, and SJS/TEN and the cumulative effect of drug-drug interactions should be considered. Further understanding of the intersections between pregnancy and drug-drug interactions in SSA is needed to ensure evidenced-based management of epilepsy in pregnant HIV+ WWE. To prevent SE, the barriers for AED treatment adherence in pregnant HIV+ women should be explored. Our review underscores the need to conduct cohort studies of HIV+ WWE in reproductive age over time and across pregnancies to capture the cumulative effect of HAART and AED to inform clinical management.

Lipid and thyroid hormone levels in children with epilepsy treated with levetiracetam or carbamazepine: A prospective observational study. Epilepsy Behav 2019; 90:15-19. [PMID: 30500483 DOI: 10.1016/j.yebeh.2018.11.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 10/30/2018] [Accepted: 11/01/2018] [Indexed: 11/24/2022]
Abstract
Although previous studies have investigated the influence of antiepileptic drugs (AEDs) on lipid profiles and thyroid hormone levels, there is little evidence regarding the effects of levetiracetam (LEV). Therefore, we conducted a prospective longitudinal study to evaluate the effects of LEV and carbamazepine (CBZ) treatment on lipid profile and thyroid hormone levels in patients newly diagnosed with epilepsy. Inclusion criteria were as follows: (a) age between 4 and 15 years, (b) diagnosis of epilepsy with at least two focal seizures within a year, and (c) newly treated with LEV or CBZ monotherapy. Serum lipid profile and thyroid hormone levels were measured before and after 1 and 6 months of AED initiation. Among the 21 included patients (LEV: 13 patients, CBZ: 8 patients), all but one patient in the LEV group continued AED monotherapy during the study period. Although triglyceride (TG) levels tended to be increased in the CBZ group (baseline: 58.3 ± 22.0 mg/dl, 1 month: 63.8 ± 21.6 mg/dl, 6 months: 92.3 ± 63.6 mg/dl, p = 0.22, analyses of variance (ANOVA)), there were no significant changes in total cholesterol (TC), TG levels, high-density lipoprotein cholesterol (HDL-C), or low-density lipoprotein cholesterol (LDL-C) in either group. Serum free thyroxine (fT4) levels were significantly decreased in the CBZ group (baseline: 1.15 ± 0.06 ng/dl, 1 month: 1.00 ± 0.16 ng/dl, 6 months: 0.98 ± 0.14 ng/dl, p = 0.03, ANOVA). In contrast, there were no significant changes in fT4 or thyroid-stimulating hormone (TSH) levels in the LEV group. The results of the present study suggest that LEV monotherapy does not affect lipid profile or thyroid function while CBZ monotherapy may cause thyroid dysfunction.

Abstract
BACKGROUND Studies of the effect of oxcarbazepine (OXC) on body growth of children with epilepsy are rare and their results are controversial. To the contrary, many studies have shown significant weight gain following valproate (VPA) treatment. PURPOSE To prospectively evaluate the effect of OXC monotherapy on growth patterns of children with epilepsy and compare it with the effect of VPA monotherapy. METHOD Fifty-nine otherwise healthy children, aged 3.7-15.9 years, with primary generalized, partial or partial with secondary generalization seizure disorder, were included in the study. Twenty six children were placed on OXC and thirty three on VPA monotherapy. Body weight (BW), height and body mass index (BMI) as well as their standard deviation scores (SDS), were evaluated prior to as well as 8 months post initiation of OXC or VPA therapy. RESULTS Eight months post OXC-treatment, BW, SDS-BW, BMI and SDS-BMI increased significantly. The increase was similar to that observed in the VPA group. An additional 15.4% of children in the OXC group and 21.2% in the VPA group became overweight or obese. The effect of both OXC and VPA therapy on linear growth did not reach statistical significance. CONCLUSION Similarly to VPA, OXC monotherapy resulted in a significant weight gain in children with epilepsy. Careful monitoring for excess weight gain along with counseling on adapting a healthy lifestyle should be offered to children on OXC therapy.

Abstract
Objectives: The prevalence of obesity is rapidly increasing among Indian children, who, in general, are more prone to develop metabolic complications at an early age. Valproate and phenytoin are commonly used antiepileptic drugs in children. This study aimed to assess the parameters of the metabolic syndrome in Indian children with epilepsy on valproate or phenytoin monotherapy. Methods: This cross-sectional study recruited children from the Pediatric Epilepsy Clinic, Department of Pediatrics, Kalawati Saran Children Hospital, New Delhi from March 2012 to September 2012. All consecutive children diagnosed with epilepsy as per International League Against Epilepsy definition aged 3–18 years on valproate or phenytoin monotherapy for at least 6 months were enrolled at a tertiary care children's hospital in Northern India. After clinical and anthropometric evaluation (including body mass index [BMI] and waist circumference), the blood samples were analyzed for fasting serum glucose, total cholesterol, high-density lipoprotein-cholesterol, and serum triglyceride. Results: Children with BMI >95th centile and waist circumference >90th centile were not significantly different among children on valproate and phenytoin monotherapy. Children on valproate had significantly higher mean serum triglyceride (96.9 mg/dL vs. 77.6 mg/dL; P < 0.001) and total cholesterol (148.3 mg/dL vs. 132.8 mg/dL; P = 0.002) levels as compared to children on phenytoin monotherapy. Conclusions: The lipid abnormalities may be observed in children on valproate or phenytoin therapy and may warrant periodic screening.

Toxicological evaluation of sediment samples spiked with human pharmaceutical products: Energy status and neuroendocrine effects in marine polychaetes Hediste diversicolor. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2015; 118:27-36.

Abstract
There is a lack of studies about the ecotoxicology of pharmaceutical products on marine environment. To predict possible adverse effects of pharmaceutical products on benthic biota, polychaetes Hediste diversicolor were exposed for 14-days to pharmaceutical-spiked sediments under laboratory conditions. Carbamazepine (CBZ), ibuprofen (IBP) and propranolol (PRO) at concentrations of 500ngg(-1), 50ngg(-1), 5ngg(-1), 0.5ngg(-1) and 0.05ngg(-1), fluoxetine (FX) and 17α-ethynylestradiol (EE2) at concentrations of 100ngg(-1), 10ngg(-1), 1ngg(-1), 0.1ngg(-1) and 0.01ngg(-1), including environmental concentrations (underlined), were spiked in marine sediment samples. After the exposure, cellular energy status (total lipids content - TLP; and mitochondrial electron transport activity - MET), metabolism of monoamines (monoamine oxidase activity - MAO) and inflammation properties (cyclooxygenase activity - COX) were observed in polychaetes. CBZ increased TLP content and MET activity, and decreased MAO activity in polychaetes. IBP did not interfere on the TLP level, but on the MET and MAO activities (environmental concentrations). FX did not cause changes in the energy status. Therefore, environmental concentration diminished MAO activity. EE2 did not affect the energy status, however, MAO activity was significantly lower in polychaetes exposed to environmental concentration. PRO increased TLP level in polychaetes, but not MET activity. MAO activity was significantly lower for polychaetes exposed to environmental concentration. Except FX, all pharmaceuticals showed anti-inflammatory properties confirmed by the decrease of COX activity. Pharmaceutical products affected H. diversicolor physiology and health. As a benthic top predator, adverse effects on sea-worms can potentially culminate in ecosystem perturbations.

Abstract
Evidence from epidemiological, longitudinal, prospective, double-blinded clinical trials as well as case reports documents age-accelerated atherosclerosis with increased carotid artery intima media thickness (CA-IMT) in patients with epilepsy. These findings raise concern regarding their implications for age-accelerated cognitive and behavioral changes in midlife and risk of later age-related cognitive disorders including neurodegenerative processes such as Alzheimer's disease (AD). Chronic epilepsy, cerebral atherosclerosis, and age-related cognitive disorders including AD share many clinical manifestations (e.g. characteristic cognitive deficits), risk factors, and structural and pathological brain abnormalities. These shared risk factors include increased CA-IMT, hyperhomocysteinemia (HHcy), lipid abnormalities, weight gain and obesity, insulin resistance (IR), and high levels of inflammatory and oxidative stresses. The resulting brain structural and pathological abnormalities include decreased volume of the hippocampus, increased cortical thinning of the frontal lobe, ventricular expansion and increased white matter ischemic disease, total brain atrophy, and β-amyloid protein deposition in the brain. The knowledge that age-accelerated atherosclerosis may contribute to age-accelerated cognitive and behavioral abnormalities and structural brain pathologies in patients with chronic epilepsy represents an important research path to pursue future clinical and management considerations.

Abstract
Treatment of epileptic patients with valproic acid (VPA) may be associated with substantial weight changes that may increase morbidity and impair adherence to the treatment regimen. VPA-induced weight gain seems to be associated with many metabolic disturbances; the most frequent are hyperinsulinemia and insulin resistance, hyperleptinemia and leptin resistance. Patients who gain weight during VPA therapy can develop dyslipidemia and metabolic syndrome that are associated with long-term vascular complications such as hypertension and atherosclerosis. Moreover, an elevation in the levels of uric acid and homocysteine, together with oxidative stress, may contribute to atherosclerotic risk in patients under long-term therapy with VPA. The aim of this review is to discuss the metabolic and endocrine effects of VPA chronic treatment in patients with epilepsy.

Abstract
OPINION STATEMENT The most-used treatments for epilepsy worldwide are older-generation drugs such as phenytoin, carbamazepine, phenobarbital, and valproic acid, which have prominent enzymatic effects. Our sense of comfort with these treatments is starting to fade, however, as more and more potential long-term consequences of these drugs come to light. Epidemiologic studies demonstrate that ischemic disease of the heart and brain is more common among patients with epilepsy. Enzyme-inducing drugs are associated with elevations in a host of surrogate markers of vascular risk, suggesting that they could be responsible for increased rates of cardiovascular and cerebrovascular disease. The enzyme-inhibiting drug valproate may have adverse consequences of its own pertaining to glucose and lipid metabolism. These effects stand in addition to those well established in the literature regarding bone metabolism, hormonal abnormalities, and drug-drug interactions. Because patients with epilepsy require medication for years, and often for life, it is difficult to justify the long-term use of these agents when there are capable alternatives. Many of the adverse effects of the older drugs appear to be rapidly reversible, prompting consideration of whether patients who are currently treated with these agents should be switched to alternative therapies, even in the absence of obvious side effects. Newer medications without effects on hepatic enzymes likely do not have these chronic metabolic consequences, and we recommend their use over older-generation drugs whenever possible.

Abstract
We prospectively examined the effects of valproic acid on the endocrine system and metabolic variables in epileptic children. Patients with newly diagnosed idiopathic epilepsy were included in the study. Laboratory and clinical variables were assessed before and after 6 and 12 months of treatment. In total, 30 patients (mean age, 8.6 +/- 4.4 years S.D.) were investigated. Body mass index and body mass index standard deviation scores of patients increased significantly during treatment. Although there was no statistical significance regarding fasting glucose, serum insulin, triglyceride, and high-density lipoprotein cholesterol levels and the insulin resistance index, a statistically significant increase in total and low-density lipoprotein cholesterol levels had occurred after 12 months of valproic acid treatment. At the end of the study period, four patients were obese, and six patients were overweight. There was a significant correlation between serum levels of valproic acid and body mass index at month 6 of treatment. There was no significant change in androgen hormone levels during treatment in the prepubertal group. Body mass index and body mass index standard deviation scores increased during the first 6 months of valproic acid treatment. Patients treated with valproic acid should be regularly followed for obesity.

Abstract
Reports of decreased serum 25-hydroxyvitamin D (25-OHD) and altered bone metabolism associated with antiepileptic drug (AED) treatment are inconsistent and predominantly restricted to adults. In this cross-sectional observational study, the aim was to evaluate the influence of AED treatment on vitamin D status and markers of bone turnover in children with epilepsy. In 38 children taking AEDs and 44 healthy control subjects, blood samples were collected to determine the levels of serum 25-OHD, intact parathyroid hormone (iPTH), calcium (Ca), phosphate (P), bone alkaline phosphatase (BAP), osteocalcin (OC) and C terminal telopeptide of type I collagen (ICTP). More than 75% of the patients were vitamin D deficient (serum 25-OHD<20 ng/mL) and 21% of the patients had an insufficient vitamin D status (serum 25-OHD=20-30 ng/mL). In the patients, the serum levels of OC (p = 0.002) and BAP (p < 0.001) were significantly increased, but ICTP (p = 0.002) concentrations were significantly decreased compared with the control group. When patients where divided into two groups according to their medication (mono- or polytherapy), significantly lower 25-OHD (p = 0.038) and ICTP (p = 0.005) levels and elevated BAP (p = 0.023) concentrations were found in patients under polytherapy. An association between 25-OHD and the measured bone markers could not be determined. Our results indicate that the prevalence of vitamin D deficiency in epilepsy patients under AED treatment is high, especially under polytherapy, and alteration markers of bone formation and resorption suggests an accelerated skeletal turnover. The routine monitoring of serum 25-OHD and vitamin D supplementation on an individual basis should be considered.

Abstract
Epilepsy is a chronic disorder often requiring years of treatment. Accordingly, adverse effects of epilepsy and its treatment can impact general health for many decades. The psychological consequences of epilepsy are well documented, although the metabolic consequences of the treatment of epilepsy have only recently received attention. Antiepileptic drugs (AEDs) are well known to alter weight, causing either weight gain or weight loss. The mechanism by which this occurs remains to be fully understood, although there appears to be an effect on lipid and glucose metabolism. This chapter examines current data available on the adverse effects of individual AEDs on somatic weight, serum lipid profile, and glucose metabolism. These issues are of importance to neurologists caring for patients with epilepsy.

Abstract
The purpose of this review is to examine what is known about cognitive and brain aging in elders with chronic epilepsy. We contend that much remains to be learned about the ultimate course of cognition and brain structure in persons with chronic epilepsy and concern appears warranted. Individuals with chronic epilepsy are exposed to many risk factors demonstrated to be associated with abnormal cognitive and brain aging in the general population, with many of these risk factors present in persons with chronic epilepsy as early as midlife. We suggest that a research agenda be developed to systematically identify and treat known modifiable risk factors in order to protect and promote cognitive and brain health in aging and elder persons with chronic epilepsy.

Abstract
OBJECTIVE Lipid abnormalities and thyroid dysfunction have been reported in patients treated with antiepileptic drugs. The aim of this study was to evaluate prospectively the association between thyroid and lipid profile in children treated with carbamazepine (CBZ) monotherapy. MATERIALS AND METHODS Thyroid function was evaluated in 18 epileptic children, previously reported with CBZ-induced changes in serum lipid profile, before and at 6, 12 and 24 months of CBZ monotherapy. RESULTS All children had normal thyroid function before the initiation of CBZ treatment. During CBZ therapy thyroid dysfunction, with increased thyrotropin (TSH) and decreased thyroxine (T4), free thyroxine (FT4) and triiodothyronine (T3) was found, while, significant association was revealed between serum low-density lipoprotein cholesterol (LDL-C) and TSH levels at 6 (r=0.469; p=0.043) and 12 (r=0.730; p=0.001) months of treatment. CONCLUSION Lipid abnormalities may be associated with thyroid hormone disturbance in children treated with CBZ monotherapy. Since thyroid dysfunction and hypercholesterolemia are both associated with a higher atherosclerotic risk special attention and further studies are needed in epileptic patients treated with CBZ monotherapy.

Abstract
Solubilization capacity and structural transformations in nonionic microemulsions characterized by a large continuous isotropic region forming dilutable self-assembled nanodroplets containing solubilized carbamazepine, were studied along dilution lines 73 and 82 (70 and 80 wt% surfactant and 30 and 20 wt% of oil phase, respectively). The preparations were based on pharma-grade ingredients, water, R-(+)-limonene, ethanol, propylene glycol, and Tween 60. Solubilization capacity (SC) of the drug was dependent on the microstructure of the microemulsion and on the surfactant-to-oil phase weight ratio. The SC in the concentrate (reversed micelles) was 15 times higher than its solubility in the oil. Transition of the W/O microemulsion to a bicontinuous phase and to O/W droplets were indentified by electrical conductivity, viscosity, SAXS, and SD-NMR measurements. Once the system is diluted to 90 wt% aqueous phase, the SC is 10 and 16-fold higher, along dilution lines 73 and 82, respectively, than in pure water. Being solubilized, carbamazepine serves as a cosurfactant therefore it affects the curvatures of the microstructures and consequently the boundaries of the structural regions and the transition points between the different phases. Dilutable microemulsions are promising new carbamazepine vehicles for oral intake.

Abstract
BACKGROUND Carbamazepine and valproate are drugs of first choice for epilepsy. Despite the lack of hard evidence from individual randomized controlled trials, there is strong clinical belief that valproate is the drug of choice for generalized epilepsies and carbamazepine for partial epilepsies. OBJECTIVES To overview the best evidence comparing carbamazepine and valproate monotherapy SEARCH STRATEGY Our search strategy included: (a) MEDLINE 1966-99, (b) The Cochrane Library 1999 issue 4, (c) The trial register of the Cochrane Epilepsy Group (d) the pharmaceutical industry. SELECTION CRITERIA Randomized controlled trials comparing carbamazepine and valproate monotherapy for epilepsy. DATA COLLECTION AND ANALYSIS This was an individual patient data review. Outcome measures were time to withdrawal of allocated treatment, time to 12 month remission, and time to first seizure post randomization. Data were analysed using the stratified Logrank test with results expressed as hazard ratios (HR) (95% CI), where HR>1 indicates an event is more likely on valproate. A test for an interaction between treatment and epilepsy type (partial versus generalized) was also undertaken. MAIN RESULTS Results Data were available for 1265 patients from five trials, representing 85% of the patients recruited into the eight trials that met our inclusion criteria. The main overall results (HR 95% CI) were: Time to treatment withdrawal 0.97 (0.79-1.18), 12 month remission 0.87 (0.74-1.02), first seizure 1.09 (0.96-1.25) suggesting no overall difference for these outcomes. The test for an interaction between treatment and epilepsy type was non significant for time to treatment withdrawal and 12 month remission, but significant for time to first seizure. The age distribution of adults classified as having a generalized epilepsy indicate that significant numbers of patients may have had their epilepsy misclassified. REVIEWER'S CONCLUSIONS We have found some evidence to support the policy of using carbamazepine as the first treatment of choice in partial epilepsies, but no evidence to support the choice of valproate in generalized epilepsies, but confidence intervals are too wide to confirm equivalence. Misclassification of patients may have confounded our results, and has important implications for the design and conduct of future trials.
