Clinical Profile and Changes of Serum Lipid Levels in Epileptic Patients after Cerebral Infarction

Frailty as a comprehensive health measure beyond seizure control in patients with epilepsy: A cross-sectional study

OBJECTIVE

Due to the high clinical heterogeneity of epilepsy, there is a critical need for novel metrics aimed at capturing its biological and phenotypic complexity. Frailty is increasingly recognized in various medical disciplines as a useful construct to understand differences in susceptibility to adverse outcomes. Here, we develop a frailty index (FI) for patients with epilepsy (PwE) and explore its association with demographic and clinical features.

METHODS

In this cross-sectional study, we consecutively enrolled 153 PwE from an outpatient epilepsy clinic. Participants were assessed for various health deficits to calculate the FI. Associations between FI and demographic/clinical features, antiseizure medications (ASMs), and patient-reported outcomes were analyzed using general linear models and Spearman correlation.

RESULTS

The median age at the time of study visit was 47 years (interquartile range = 33-60), and 89 (58.2%) patients were females. Multiple linear regression revealed that the developed 33-item FI showed an independent association with age, female sex, higher body mass index, family history of epilepsy, intellectual disability, and the number of ASMs used. A robust analysis of covariance showed higher FI levels in patients using cytochrome P450 3A4-inducer ASMs. We found a moderate positive correlation between FI and psychological distress, lower quality of life, and physical frailty, measured by the Hospital Anxiety and Depression Scale, Quality of Life in Epilepsy Inventory-10, and handgrip strength, respectively. Finally, a weak association was observed between higher FI scores and an increased number of epileptic falls.

SIGNIFICANCE

This study highlights the significance of frailty as a comprehensive health measure in epilepsy. It suggests that frailty in this specific population is not only a manifestation of aging but is inherently linked to epilepsy and treatment-related factors. Future research is warranted to validate and refine the FI in diverse epilepsy populations and investigate its impact on specific adverse outcomes in longitudinal studies.

Dietary and lifestyle behavior in adults with epilepsy needs improvement: a case-control study from northeastern Poland

BACKGROUND

Several factors predispose individuals with epilepsy to chronic diseases. Among them, nutrition and lifestyle factors have not been sufficiently studied. Therefore, the aim of this study was to evaluate patients with epilepsy in terms of diet, body composition and physical activity compared to healthy sex- and age-matched subjects to investigate whether there are risk factors for nutritional deficiencies and risk factors for the development of metabolic diseases.

METHODS

The case-control study involved 60 epileptic male and female volunteers and 70 healthy controls matched according to age and sex. Medical information was collected during the study, and a detailed questionnaire regarding eating and lifestyle habits was conducted. Physical activity was evaluated using the International Physical Activity Questionnaire (IPAQ). Nutritional status was assessed by bioelectric impedance. Venous blood samples were taken for lipid and 25-hydroxyvitamin D3 (25(OH)D3) analyses.

RESULTS

A tendency toward an increase in LDL cholesterol was found in the individuals with epilepsy. Significantly higher body fat and insignificantly higher visceral fat were found in epileptic men than in healthy men. In epileptic women, a tendency toward a lower lean body mass was found. Patients with epilepsy were more sedentary, consumed less cottage cheese, fruit, pulses, nuts and seeds, vitamin C and potassium, and consumed more sugar-sweetened soda, fat and sodium than healthy people. On a positive note, individuals with epilepsy consumed less coffee and alcoholic beverages. More than 80% of the epileptic volunteers had diets that were low in folic acid, vitamin D and calcium, but a similar tendency was observed in the healthy volunteers. A higher percentage of the patients with epilepsy had diets that were low in niacin, vitamin C and potassium than the control group (25% vs. 7, 50% vs. 31% and 73 vs. 56%, respectively). A significantly lower serum concentration of 25(OH)D3 was observed in epileptic individuals and was found to be positively modulated by physical activity.

CONCLUSIONS

The results indicate that several behavior-related habits, which may predispose epileptic people to cardiovascular disease, need to be improved. For this reason, patients with epilepsy should be provided with more comprehensive medical care, including advice on nutrition and physical activity.

Effects of long-term anti-seizure medication monotherapy on all-cause death in patients with post-stroke epilepsy: a nationwide population-based study in Taiwan

OBJECTIVE

We aim to compare the effect of long-term anti-seizure medication (ASM) monotherapy on the risk of death and new ischemic stroke in patients with post-stroke epilepsy (PSE).

PATIENTS AND METHODS

We identified all hospitalized patients (≥ 20 years) with a primary diagnosis of ischemic or hemorrhagic stroke from 2001 to 2012 using the National Health Insurance Research Database in Taiwan. The PSE cohort were defined as the stroke patients (1) who had no epilepsy and no ASMs use before the index stroke, and (2) who had epilepsy and ASMs use after 14 days from the stroke onset. The patients with PSE receiving ASM monotherapy were enrolled and were categorized into phenytoin, valproic acid, carbamazepine, and new ASM groups. We employed the Cox regression model to estimate the unadjusted and adjusted hazard ratios (HRs) with 95 % confidence intervals (CIs) of death and new ischemic stroke within 5 years across all groups, using the new ASM group as the reference.

RESULTS

Of 6962 patients with PSE using ASM monotherapy, 3917 (56 %) were on phenytoin, 1623 (23 %) on valproic acid, 457 (7 %) on carbamazepine, and 965 (14 %) on new ASMs. After adjusting for confounders, compared with new ASM users, phenytoin users had a higher risk of death in 5 years (HR: 1.64; 95 % CI: 1.06-2.55). On the other hand, all ASM groups showed a similar risk of new ischemic stroke in 5 years.

CONCLUSIONS

Among patients with PSE on first-line monotherapy, compared to new ASMs, use of phenytoin was associated with a higher risk of death in 5 years.

Serum lipoprotein and RBC rigidity index to predict cerebral infarction in patients with carotid artery stenosis

OBJECTIVE

This study aims to determine the risk factors and to predict the occurrence of cerebral infarction in patients with carotid artery stenosis.

METHODS

Two hundred and one subjects with carotid artery stenosis were retrospectively selected from Jinshan Branch of Shanghai Sixth People's Hospital, 115 cases of which with cerebral infarction and 86 without it. Clinical tests were performed including coagulation indices, fasting glucose, serum lipid, and blood rheology. Logistic regression analyses were used to identify the risk factors. Regression model was established, and receiver operating characteristic (ROC) curve was applied to analyze its diagnostic value.

RESULTS

Our data indicated that apolipoprotein AI (OR = 0.051, 95% CI: 0.009-0.295), lipoprotein (a) (OR = 1.003, 95% CI: 1.001-1.005), and RBC rigidity index (OR = 0.383, 95% CI: 0.209-0.702) were independent risk factors. Area under the curve (AUC) of the regression model = 0.78, with the sensitivity of 73.9% (95% CI: 64.9%-81.7%) and specificity of 69.2% (95% CI: 52.4%-83.0%). Prediction probability was determined while logistic regression score >0.748 defaulted as high-risk status. High-risk ratios were 80% in progressive cerebral infarction and 72% in nonprogressive cerebral infarction (P > .05), respectively, while significant differences were found when both compared with controls (P < .001).

CONCLUSIONS

We show herein that the regression model based on apolipoprotein AI, lipoprotein (a), and RBC IR is a promising tool to predict the occurrence of cerebral infarction in patients with carotid artery stenosis. However, identification of novel diagnostic markers for progressive cerebral infarction is still necessary.
