Abstract
Background and objective Epilepsy is the commonest serious neurological condition and around 50 million people live with epilepsy (PWE). Primary and secondary generalised tonic-clonic seizures (GTCS) together constitute up to 50% of adult and adolescent epilepsy. GTCS respond well to broad-spectrum AEDs like valproate, phenytoin, levetiracetam, lamotrigine, and topiramate. Carbamazepine and oxcarbazepine are considered alternatives. Metabolic derangements with the conventional AEDs (phenytoin causes loss of bone mass in women, phenytoin and carbamazepine produce increases in serum lipid and C-reactive protein, weight gain with valproate) are well documented. But, there is limited data regarding the effect of the newer AEDs on metabolic parameters. Thus, this study was undertaken to assess the effects of the newer AEDs on the metabolic profile of patients with epilepsy. Material and methods A prospective observational study was conducted in the Department of Pharmacology, in collaboration with the Department of Neurology at S.C.B. Medical College and Hospital, Cuttack. 100 diagnosed patients with GTCS receiving monotherapy of either conventional or newer anti-epileptics were included in the study. Their metabolic parameters like total cholesterol, serum sodium, serum TSH and fasting blood glucose were collected at baseline, three months, and six months. ADRs were collected during the entire study period and causality assessment was done using WHO-UMC Causality Assessment Scale. All the data were analysed using SPSS 20.0 after applying appropriate statistical tests. Results There was a significant increase in total cholesterol in all four groups (p=0.002) but a pathological increase in the phenytoin and oxcarbazepine groups. There was a significant rise in the serum TSH levels in all groups except levetiracetam, but a pathological increase was seen with phenytoin and valproate, i.e., the conventional ones. Statistically significant hyponatremia was seen with valproate and oxcarbazepine. A rise in the FBS was seen with both phenytoin and valproate (p=0.002) but a pathological rise was seen with phenytoin. Out of the total reported ADRs, 53.5% were seen with conventional AEDs, and the rest 46.5% were seen with newer ones. Conclusion The advent of newer anti-epileptic drugs has unfolded wider horizons to the treatment of epilepsy. Each of these drugs has a unique mechanism of action, making it less prone to resistance. Metabolic derangements are a key determinant in the compliance of these drugs as they can predispose to other co-morbidities. Periodic monitoring of the various metabolic parameters is useful and together with patient counselling can improve the effectiveness of the anti-epileptic drugs.

[PMID: 36726420 PMCID: PMC9885511 DOI: 10.4103/jmss.jmss_138_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 01/04/2022] [Accepted: 01/28/2022] [Indexed: 02/03/2023]
Abstract
To develop a wearable device that can detect epilepsy seizures. In particular, due to their prevalence, attention is focused on detecting the generalized tonic-clonic seizure (GTCS) type. When a seizure is detected, an alert phone call is initiated and an alarm SMS sent to the nearest health-care provider (and/or a predesignated family member), including the patient's location as global positioning system (GPS) coordinates. A wearable belt is developed including an Arduino processor that constantly acquires data from four different sensing modalities and monitors the acquired signal patterns for abnormalities. The sensors are a heart rate sensor, electromyography sensor, blood oxygen level (oxygen saturation) sensor, and an accelerometer to detect sudden falls. Higher-than-normal threshold levels are established for each sensor's signal. If two or more signal measurements exceed the corresponding threshold value for a predetermined time interval, then the seizure alarm is triggered. Clinical trials were not pursued in this study as this is the initial phase of system development (phase 0). Instead, the instrumented belt seizure detection prototype was tested on nine healthy individuals mimicking, to some degree, seizure symptoms. A total of eighteen trials took place of which half had <2 sensor thresholds exceeded and no alarm, whereas the other half resulted in activating the alarm when two or more sensor thresholds were exceeded for at least the predetermined time interval corresponding to each of the higher-than-normal sensor readings. For each trial that triggered the alarm when a seizure was detected, the on-board GPS and global system for mobile communication (GSM) units successfully initiated an alert phone call to a predesignated number in addition to sending an SMS message, including GPS location coordinates. Continuous real-time monitoring of signals from the four different sensors allows the developed wearable belt to detect GTCS while reducing false alarms. The proposed device produces an important alarm that may save a patient's life.

Abstract
Background: Epilepsy (Ep) is a chronic neural disease. The diagnosis of epilepsy depends on detailed seizure history and scalp electroencephalogram (EEG) examinations. The automatic recognition of epileptic EEG is an artificial intelligence application developed from machine learning (ML). Purpose: This study compares the classification effects of two kinds of classifiers by controlling the EEG data source and characteristic values. Method: All EEG data were collected by GSN HydroCel 256 leads and high-density EEG from Xiangya Third Hospital. This study used time-domain features (mean, kurtosis and skewness processed by empirical mode decomposition (EMD) and three IMFs), a frequency-domain feature (power spectrum density, PSD) and a non-linear feature (Shannon entropy). Support vector machine (SVM) and gradient-boosting decision tree (GBDT) classifiers were used to recognize epileptic EEG. Result: The result of the SVM classifier showed an accuracy of 72.00%, precision of 73.98%, and an F1_score of 82.28%. Meanwhile, the result of the GBDT classifier showed a sensitivity of 98.57%, precision of 89.13%, F1_score of 93.40%, and an AUC of 0.9119. Conclusion: The comparison of GBDT and SVM by controlling the variables of the feature values and parameters of a classifier is presented. GBDT obtained the better classification accuracy (90.00%) and F1_score (93.40%).

Abstract
Introduction: The etiologies of acute symptomatic seizures (ASS) differ across the globe. We aimed to evaluate the etiological spectrum of acute seizures and to observe the pattern of seizure types among study participants. Methodology: We conducted this prospective study from 2016 to 18. We included all patients aged 20 years or older, presenting with ASS. We excluded those with pseudoseizures. We performed appropriate descriptive analyses to describe the demographic details, etiology of ASS, and pattern of ASS. Results: One hundred and thirty-eight patients were enrolled, constituting about 0.8% of total hospital admissions. The mean age at presentation was 44.33 ± 17.73 years. The most common etiologies for ASS were cerebrovascular accidents (CVA - 32.6%), neuroinfections (26.8%), metabolic derangements (13%), alcohol withdrawal (10.9%), and intracranial tumors (4.3%). 71% of the patients presented with only a single episode of ASS. The predominant type of seizure was generalized tonic-clonic seizures, seen in 70.2% of all patients, followed by focal with the bilateral tonic-clonic type (15.9%) and focal seizures (10.1%). New-onset seizures presenting as status epilepticus were observed in 3.6%. Discussion: CVA and neuroinfections were the most common causes of ASS in our study, highlighting the need for community awareness of these conditions and the need to seek rapid care. The majority of our patients had only a single episode of seizures, with generalized seizures being the most common type, followed by focal onset seizures.

Abstract
The concept of Epilepsy Treatment Gap (ETG) refers to the proportion of people with epilepsy who are not being appropriately treated. The ETG in the USA approaches 10%, with historically underserved populations and rural populations disproportionately affected. The ETG in Low-and Middle-Income Countries (LMIC) is reported to be 5-10 times higher than in high-income countries. The growing availability of reliable internet access offers a unique opportunity to provide better care to children and adults with epilepsy. In this paper we explore various telehealth (TH) initiatives that have leveraged the availability of easy and free access to an internet connection in reducing the ETG in underserved regions of the world. We describe several interventions targeted to reach patients and providers in rural areas of the United States and in LMIC. First, we examine initiatives that were developed to improve patient access to coordinated care and education regarding epilepsy and seizures. Next, we describe an intervention designed to improve knowledge of epilepsy diagnosis and treatment for providers in LMIC. We conclude with a brief overview of the use of virtual tools in diminishing the ETG.

Abstract
Aims This study was undertaken to determine the prevalence of active epilepsy, assess the sociodemographic profile, and psychological aspects of epilepsy in the Jaipur district of Rajasthan, India. Methods We conducted a community-based, cross-sectional observational study covering both rural (n = 165,660) and urban (n = 179,142) populations of Jaipur district using a house-to-house survey. An adapted, pre-designed World Health Organization screening questionnaire was used to identify the cases. Those confirmed by neurologists as true seizures were included in the study. Cases were classified as per the International League against Epilepsy recommendation. Global Mental Health Assessment Tool electronic questionnaire was used to analyze psychological aspects of cases. The caregivers of the patients participated in the knowledge, attitude, and practice (KAP) survey. Results A total of 380 patients (258 men, 122 women) were identified with active epilepsy. The estimated prevalence of active epilepsy was 1.1/1,000 population and 71% of cases belonged to low socioeconomic classes. Primary treatment gap was documented in 18.8% of cases in our study, 38% of cases were non-compliant to treatment with poorer compliance in those on pol-therapy, 76% had some psychiatric disorder, anxiety and depression being the commonest, and positive family history of epilepsy was found in 4.7%. KAP survey revealed that only 15% of the respondents believed that epilepsy is non-curable, 74% denied its infectious nature, 26% believed that epilepsy occurs due to past sins, and 81% said that they would not marry persons with epilepsy. Conclusion A relatively low prevalence (1.1/1,000) of active epilepsy and a smaller primary treatment gap (18.8%) was found in our study population. Almost three-fourth of cases had an associated psychological problem, Though caregivers were aware of the nature of disease, majority would not prefer to marry a person suffering from epilepsy.

Abstract
Perampanel (Fycompa®), an orally-active, selective, noncompetitive α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist, is a first-in-class antiepileptic drug (AED) offering the convenience of once-daily administration. In the EU and US, perampanel is approved in patients with epilepsy aged ≥12 years for the adjunctive treatment of primary generalized tonic-clonic seizures (GTCS) and partial-onset seizures (POS; with or without secondary generalization). In phase III trials of 17 or 19 weeks' duration, add-on perampanel ≤12 mg/day significantly improved seizure control in patients aged ≥12 years who were experiencing either primary GTCS or POS (with or without secondary generalization), despite ongoing treatment with stable dosages of one to three AEDs. Improvements in seizure control were maintained for up to 2 years in extensions of these core studies. Perampanel also provided sustained seizure control for up to ≈4 years in an extension of two phase II studies in patients aged ≥18 years with drug-resistant POS. Adjunctive perampanel therapy was generally well tolerated. Treatment-emergent adverse events were most commonly CNS-related (e.g. dizziness, somnolence, fatigue and irritability) and dose-related; however, most were of mild to moderate intensity. Clinical experience with perampanel is accumulating, although comparative studies and pharmacoeconomic data that could assist in positioning it relative to other AEDS that are approved and/or recommended as adjunctive therapy are lacking. Nonetheless, on the basis of its overall clinical profile and unique mechanism of action, perampanel is a useful additional adjunctive treatment option for patients with drug-resistant POS, with or without secondary generalization, and primary GTCS.

Effect of experimentally induced hepatic and renal failure on the pharmacokinetics of topiramate in rats. BIOMED RESEARCH INTERNATIONAL 2014; 2014:570910. [PMID: 25009818 PMCID: PMC4070280 DOI: 10.1155/2014/570910] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/23/2013] [Revised: 04/07/2014] [Accepted: 05/24/2014] [Indexed: 11/17/2022]
Abstract
We aimed to investigate the effect of induced hepatic and renal failure on the pharmacokinetics of topiramate (TPM) in rats. Twenty-four Sprague-Dawley rats were used in this study. Renal or hepatic failure was induced by a single i.p. dose of 7.5 mg/kg cisplatin (n = 8) or 0.5 mL/kg carbon tetrachloride (CCl4) (n = 8), respectively. Three days after cisplatin dose or 24 h after CCl4 dose, the rats were administered a single oral dose of 20 mg/kg TPM. The plasma samples were quantified by LC-MS/MS method. Compared to control, plasma concentration-time profile in CCl4-treated and, to a lesser extent, in cisplatin-treated rats decreased more slowly particularly in the elimination phase. TPM oral clearance (CL/F) in CCl4-treated group was significantly lower than that in control (P < 0.001), whereas AUC0-∞, T1/2, and Vd/F were significantly higher in CCl4-treated rats compared to the control (P < 0.01). The CL/F was not significantly different between cisplatin-treated rats and control (P > 0.05). However, in cisplatin-treated rats, the T1/2 and Vd/F were significantly higher than that in the control group (P < 0.01). Both conditions failed to cause a significant effect on Cmax or Tmax. The present findings suggest that induced hepatic or renal failure could modify the pharmacokinetic profile of TPM in the rat.
