Proposed Recommendations for the Management of Depression in Adults with Epilepsy: An Expert Consensus.

INTRODUCTION: Experts agree that there is a need for protocols to guide health professionals on how to best manage psychiatric comorbidities in patients with epilepsy (PWE). We aimed to develop practical recommendations for key issues in the management of depression in PWE. METHODS: This was a qualitative study conducted in four steps: (1) development of a questionnaire on the management of depression in PWE to be answered; (2) literature review and, if evidence from guidelines/consensus or systematic reviews was available, drafting initial recommendations; (3) a nominal group methodology for reviewing initial recommendations and formulating new recommendations on those issues without available evidence; and (4) drafting and approving the final recommendations. A scientific committee (one neurologist and one psychiatrist) was responsible for the development of the project and its scientific integrity. The scientific committee selected a panel of experts (nine neurologists and nine psychiatrists with experience in this field) to be involved in the nominal group meetings and to formulate final recommendations. RESULTS: Fifteen recommendations were formulated. Four on the screening and diagnosis: screening and diagnosis of depression, evaluation of the risk of suicide, and diagnosis of depression secondary to epilepsy; nine on the management of depression: referral to a psychiatrist, selection of the antiseizure medication, change of antiseizure medication, antidepressant treatment initiation, selection of antidepressant, use of antidepressants during pregnancy, use of psychotherapy, antidepressant treatment duration, and discontinuation of antidepressant treatment; two on the follow-up: duration of the follow-up under usual conditions, and follow-up of patients at risk of suicide. CONCLUSION: We provide recommendations based on expert opinion consensus to help healthcare professionals assess depression in PWE. The detection and treatment of major depressive disorders are key factors in improving epilepsy outcomes and avoiding suicide risk.

MONOZEB: Long-term observational study of eslicarbazepine acetate monotherapy.

AIM: The aim of the study was to evaluate the effectiveness and tolerability of eslicarbazepine acetate (ESL) when used as monotherapy for 1 year or more in routine clinical use in patients with focal seizures in epilepsy clinics in Spain. METHODS: This is a retrospective, observational, noninterventional study. Eligible patients were aged ≥18 years, had focal seizures, and started on ESL ≥1 year before database closure. Primary endpoint was the following: proportion seizure-free for ≥6 months at 1 and 2 years. Secondary endpoints included retention on ESL monotherapy at 1 and 2 years, seizure frequency change, seizure worsening, and side effects. Other analyses included seizure freedom from baseline to 1 and 2 years and outcomes in special populations. RESULTS: Four hundred thirty-five patients were included (127 on first-line monotherapy and 308 converting to ESL monotherapy): median daily dose was 800 mg at all time points; 63.2% were seizure-free at 1 year, 65.1% at 2 years, and 50.3% for the entire follow-up. Mean duration of ESL monotherapy was 66.7 months; retention was 88.0% at 1 year and 81.9% at 2 years. Mean reduction in seizure frequency was 75.5% at last visit. Over the entire follow-up, seizure worsening was seen in 22 patients (5.1%), side effects in 28.0%, considered severe in 1.8%, and leading to discontinuation in 5.7%. Dizziness, hyponatremia (sodium <135 mEq/l), and somnolence were the most frequent side effects. Outcomes in special populations (patients aged ≥65 years and those with psychiatric history or learning difficulty) were consistent with the overall population. CONCLUSIONS: Patients with focal seizures taking ESL monotherapy had excellent retention, high seizure-free rates, and good tolerability up to 2 years.

Eslicarbazepine acetate and carotid intima-media thickness in epileptic patients.

OBJECTIVE: Evaluate if eslicarbazepine acetate (ESL) in combination with other non-inducer antiepileptic drugs (AEDs) in the treatment of epilepsy may represent a positive impact in the cardiovascular risk profile. METHODS: multicentre, retrospective, observational, non-interventional, real-life study comparing patients treated with cytochrome P450 (CYP) inducer vs. ESL plus non-inducer AEDs. Primary endpoint: Carotid intima-media thickness (CIMT) measured following the Manheim Consensus criteria. RESULTS: Patients included: 163. The main demographic, clinical and vascular risk parameters were comparable between the two groups except for duration of the disease, prevalence of dyslipidemia and use of lipid-lowering drugs (significantly higher in the inducers group) and number of previous antiepileptic drugs (significantly higher in the non-inducers group). Bivariate analysis of the main endpoint showed almost significant differences (p=0.05) in CIMT measures favourable to non-inducers (average 0.617mm+SD=0.148) vs. inducers (average 0.663mm+SD=0.147). Other variables reaching statistical significance were: age >50 years (p<0.001), high blood pressure (p<0.01) and dyslipidemia (p<0.05). A multivariate analysis including these variables and biochemical vascular risk factors showed a predictor model including two variables: inducers group (p=0.031; Coefficient ß=0.234) and age >50 years (p=0.001; Coefficient ß=0.387). Regarding gender, the mean CIMT in males was significantly higher in the inducers (0.693mm; SD=0.139) than in the non- inducers groups (0.628mm; SD=0.151; p<0.05). In females the differences were not significant. SIGNIFICANCE: The use of CYP inducer AEDs is associated with a significant increase in CIMT as compared with ESL and other non-inducer AEDs. The study shows a decrease in the vascular risk measured by ultrasound criteria in male patients treated with ESL compared with patients treated with inducer AEDs.

The COL1A1 SP1 polymorphism is associated with lower bone mineral density in patients treated with valproic acid.

OBJECTIVE: The aim of this study was to determine the possible relationship between the Sp1 polymorphism of gene COL1A1 and bone metabolism disorder in individuals with epilepsy. METHODS: To this end, we carried out an observational cross-sectional study on 64 patients in monotherapy with an antiepileptic drug. The patients were classified on the basis of the presence of the 's' allele of the COL1A1 Sp1 polymorphism. RESULTS: In the patients with SS, the standardized bone mineral density (sBMD) in the left femoral neck was 1024.9±206.1 mg/cm, whereas in the patients with Ss or ss, the density was significantly lower, 917±141.4 mg/cm (P=0.027), as was the femoral t-score (0.72±1.67 vs. -0.29±1.15, P=0.01). The values in the lumbar spine were equally greater in those with SS: 1219.1±236.3 versus 1090.5±142.7 mg/cm for the sBMD (P=0.018) and 0.67±1.98 versus -0.34±1.16 for the lumbar t-score (P=0.023). The bone biomarkers showed no significant differences nor did the 25-OH vitamin D and parathormone values. In the patient group treated with valproic acid (VPA), the densitometric values were significantly lower in the Ss or ss patients compared with SS homozygotes: 887.1±142.6 versus 1120.6±198.2 mg/cm for femoral sBMD (P=0.02), 990±98.1 versus 1417±251.2 mg/cm for lumbar sBMD (P=0.001). Of the patients who were carriers of the 's' allele and who were treated with VPA, 86% achieved osteopenia values. CONCLUSION: In our study, the presence of the 's' allele of the COL1A1 Sp1 polymorphism in individuals with epilepsy was related to lower bone BMD (lumbar and femoral). This relationship seemed to be further apparent in the patients undergoing treatment with VPA.
