Effects of long term antiseizure medications on atherosclerosis

Long-term therapy with antiseizure medications (ASMs) has been associated with metabolic consequences that lead to an increase in the risk of atherosclerosis in patients with epilepsy. This study was conducted to assess the effects of ASMs on vascular risk factors namely, serum Lipid profile and C-reactive protein (CRP) in epileptic patients and to assess the correlation between the duration of the ASMs, and carotid intima media thickness (IMT). Forty three adult patient participants who were receiving ASM monotherapy for more than 2 years and 43 control patients were enrolled in this study. All participants received measurement of common carotid artery (CCA) and IMT by B-mode ultrasonography to assess the extent of atherosclerosis. Other measurements included body mass index (BMI), serum lipid profile and CRP. The correlation between duration of ASM and average carotid IMT was calculated by using the Pearson's correlation coefficient method. The majority of subjects on phenytoin 8 (66.7%) were positive for CRP. There was an equal proportion of patients on carbamazepine who were equally positive 5(50%) and negative 5(50%) for CRP. There was a statistically significant association between phenytoin consumption and CRP positivity. There was positive correlation between duration of phenytoin consumption and average IMT. There was a strong positive correlation between duration of phenobarbitone consumption and average IMT and was statistically significant. Our results also suggest that long-term use of ASMs with prominent effects on the enzyme system, including Carbamazepine, phenytoin, sodium valproate or phenobarbitone may contribute to the progression of atherosclerosis in patients with epilepsy

Global Survey of Outcomes of Neurocritical Care Patients: Analysis of the PRINCE Study Part 2

BACKGROUND: Neurocritical care is devoted to the care of critically ill patients with acute neurological or neurosurgical emergencies. There is limited information regarding epidemiological data, disease characteristics, variability of clinical care, and in-hospital mortality of neurocritically ill patients worldwide. We addressed these issues in the Point PRevalence In Neurocritical CarE (PRINCE) study, a prospective, cross-sectional, observational study. METHODS: We recruited patients from various intensive care units (ICUs) admitted on a pre-specified date, and the investigators recorded specific clinical care activities they performed on the subjects during their first 7 days of admission or discharge (whichever came first) from their ICUs and at hospital discharge. In this manuscript, we analyzed the final data set of the study that included patient admission characteristics, disease type and severity, ICU resources, ICU and hospital length of stay, and in-hospital mortality. We present descriptive statistics to summarize data from the case report form. We tested differences between geographically grouped data using parametric and nonparametric testing as appropriate. We used a multivariable logistic regression model to evaluate factors associated with in-hospital mortality. RESULTS: We analyzed data from 1545 patients admitted to 147 participating sites from 31 countries of which most were from North America (69%, N = 1063). Globally, there was variability in patient characteristics, admission diagnosis, ICU treatment team and resource allocation, and in-hospital mortality. Seventy-three percent of the participating centers were academic, and the most common admitting diagnosis was subarachnoid hemorrhage (13%). The majority of patients were male (59%), a half of whom had at least two comorbidities, and median Glasgow Coma Scale (GCS) of 13. Factors associated with in-hospital mortality included age (OR 1.03; 95% CI, 1.02 to 1.04); lower GCS (OR 1.20; 95% CI, 1.14 to 1.16 for every point reduction in GCS); pupillary reactivity (OR 1.8; 95% CI, 1.09 to 3.23 for bilateral unreactive pupils); admission source (emergency room versus direct admission [OR 2.2; 95% CI, 1.3 to 3.75]; admission from a general ward versus direct admission [OR 5.85; 95% CI, 2.75 to 12.45; and admission from another ICU versus direct admission [OR 3.34; 95% CI, 1.27 to 8.8]); and the absence of a dedicated neurocritical care unit (NCCU) (OR 1.7; 95% CI, 1.04 to 2.47). CONCLUSION: PRINCE is the first study to evaluate care patterns of neurocritical patients worldwide. The data suggest that there is a wide variability in clinical care resources and patient characteristics. Neurological severity of illness and the absence of a dedicated NCCU are independent predictors of in-patient mortality.status: publishe
