Specific profiles of new-onset vs. non-inaugural status epilepticus: From diagnosis to 1-year outcome. Front Neurol 2023; 14:1101370. [PMID: 36860570 PMCID: PMC9969963 DOI: 10.3389/fneur.2023.1101370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 01/06/2023] [Indexed: 02/05/2023] Open
Abstract
While new-onset status epilepticus (NOSE) is a harbinger of chronic epilepsy, prospective medical data are sparse in terms of specifying whether the evolution of status epilepticus (SE) and seizure expression in NOSE resembles what occurs in patients who have already been diagnosed with epilepsy [non-inaugural SE (NISE)] in all aspects apart from its inaugural nature. The aim of this study was to compare the clinical, MRI, and EEG features that could distinguish NOSE from NISE. We conducted a prospective monocentric study in which all patients ≥18 years admitted for SE over a 6-month period were included. A total of 109 patients (63 NISE and 46 NOSE cases) were included. Despite similar modified Rankin scores before SE, several aspects of the clinical history distinguished NOSE from NISE patients. NOSE patients were older and frequently had neurological comorbidity and preexisting cognitive decline, but they had a similar prevalence of alcohol consumption to NISE patients. NOSE and NISE evolve in the same proportions as refractory SE (62.5% NOSE, 61% NISE) and share common features such as the same incidence (33% NOSE, 42% NISE, and p = 0.53) and volumes of peri-ictal abnormalities on MRI. However, in NOSE patients, we observed greater non-convulsive semiology (21.7% NOSE, 6% NISE, and p = 0.02), more periodic lateral discharges on EEG (p = 0.004), later diagnosis, and higher severity according to the STESS and EMSE scales (p < 0.0001). Mortality occurred in 32.6% of NOSE patients and 21% of NISE patients at 1 year (p = 0.19), but with different causes of death occurring at different time points: more early deaths directly linked to SE at 1 month occurred in the NOSE group, while there were more remote deaths linked to causal brain lesions in the NISE group at final follow-up. In survivors, 43.6% of the NOSE cases developed into epilepsy. Despite acute causal brain lesions, the novelty related to its inaugural nature is still too often associated with a delay in diagnosing SE and a poorer outcome, which justifies the need to more clearly specify the various types of SE to constantly raise awareness among clinicians. These results highlight the relevance of including novelty-related criteria, clinical history, and temporality of occurrence in the nosology of SE.

Impact of Seizure Recurrence on 1-Year Functional Outcome and Mortality in Patients With Poststroke Epilepsy. Neurology 2022; 99:e376-e384. [PMID: 35508394 DOI: 10.1212/wnl.0000000000200609] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 03/11/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVES The functional outcome and mortality of post-stroke epilepsy (PSE) patients have not been assessed in a prospective study. Previous reports have suggested that PSE patients may suffer from prolonged functional deterioration following a seizure. In the current study, we prospectively investigated the functional outcome and mortality of PSE patients and analyzed the impact of seizure recurrence on the outcomes. METHODS This is part of the Prognosis of Post-Stroke Epilepsy (PROPOSE) study, a multicenter, prospective observational cohort study, where 392 PSE patients (at least one unprovoked seizure more than 7 days after the onset of the last symptomatic stroke) were followed for at least 1 year at eight hospitals in Japan. The current study included only PSE patients with a first-ever seizure and assessed their functional decline and mortality at 1 year. Functional decline was defined as an increase in modified Rankin Scale (mRS) score at 1 year compared to baseline, excluding death. The associations between seizure recurrence and the outcomes were analyzed statistically. RESULTS A total of 211 patients (median age of 75 years; median mRS score of 3) were identified. At 1 year, 50 patients (23.7%) experienced seizure recurrence. Regarding outcomes, 25 patients (11.8%) demonstrated functional decline, and 20 (9.5%) had died. Most patients died of pneumonia or cardiac disease (seven patients each), and no known causes of death were directly related to recurrent seizures. Seizure recurrence was significantly associated with functional decline (odds ratio 2.96 [95% CI 1.25-7.03], P=0.01), even after adjusting for potential confounders (adjusted odds ratio 3.26 [95% CI 1.27-8.36], P=0.01), but not with mortality (odds ratio 0.79 [95% CI 0.18-2.61], P=0.79). Moreover, there was a significant trend where patients with more recurrent seizures were more likely to have functional decline (8.7%, 20.6%, and 28.6% in none, 1, and 2 or more recurrent seizures, respectively; P=0.006). DISCUSSION One-year functional outcome and mortality of PSE patients were poor. Seizure recurrence was significantly associated with functional outcome, but not with mortality. Further studies are needed to ascertain whether early and adequate anti-seizure treatment can prevent the functional deterioration of PSE patients.

Abstract
A 66 year-old right-handed female was admitted to our hospital presenting with recurrent episodes of catatonic symptoms consisting of stupor, waxy flexibility, and catalepsy lasting about 5-20 minutes. A brain MRI showed no significant abnormalities. An scalp-electroencephalography (EEG) concurrent with the symptoms showed ictal EEG activities arising from the left fronto-central area, which evolved into the bilateral frontal and bilateral parietal areas together. An 18F-fluorodeoxy glucose positron emission tomography (18F-FDG-PET) 4 days after improvement of the symptoms showed hypermetabolism in the bilateral frontal and parietal lobes. Her catatonic symptoms are assumed to be due to non-convulsive status epilepticus (NCSE), namely ictal catatonia. The introduction of several anti-epileptic drugs improved the symptoms and normalized the EEG and FDG-PET findings. NCSE must be considered as one of the underlying state of catatonic symptoms because the treatment plan for acute and chronic state is different from that of catatonic syndrome due to psychiatric disorders.

Abstract
Status epilepticus (SE) is associated with high mortality and morbidity. Although SE is frequently seen in elderly patients, there is a lack of a cohesive report of outcome measures and associated factors within this population. Our aim was to systematically review studies reporting outcomes of SE among elderly patients and factors influencing these outcomes. A literature search was conducted in PubMed/MEDLINE, EMBASE, CINAHL Complete, and Cochrane Library from database conception to April 22, 2018. A total of 85 studies were included in this systematic review. The included studies show that mortality is higher in elderly patients than in adult patients. Lesional etiologies, higher number of comorbidities, NCSE, RSE, longer hospital and intensive care unit stays, and infection during hospitalization are associated with poor outcome. Future studies should consider measuring functional outcomes, comparative studies between elderly and adults and AED clinical trials specific for elderly with SE.

Abstract
Importance Status epilepticus (SE) is associated with significant morbidity and mortality. Since the late 1990s, a more aggressive management of prolonged convulsive seizures lasting longer than 5 minutes has been advocated. Objective To determine if convulsive SE mortality has decreased during a time of increasing advocacy for out-of-hospital treatment and escalating and earlier treatment protocols for prolonged seizures and SE. Data Source This systemic review and meta-analysis on studies focused on the mortality of convulsive status epilepticus was conducted by searching MEDLINE, Embase, PsychINFO, CINAHL Plus, and the Cochrane Database of Systematic Reviews between January 1, 1990, and June 30, 2017. Study Selection Studies were excluded if they had fewer than 30 participants (<20 for refractory SE), were limited to SE of single specific etiology or an evaluation of a single treatment modality, or were studies of nonconvulsive SE. Data Extraction and Synthesis Data were abstracted and their quality was assessed via a modified Newcastle-Ottawa scale independently by 2 reviewers (A.N. and T.D.G.) using the Meta-analyses of Observational Studies in Epidemiology (MOOSE) guidelines. Data were pooled using a random-effects model. Main Outcomes and Measures The main outcome measure was in-hospital mortality or 30-day case fatality expressed as proportional mortality. Results Sixty-one studies were included in the analysis. The pooled mortality ratios were 15.9% (95% CI, 12.7-19.2) for adult studies, 13.0% (95% CI, 7.2-19.0) for all-age population studies, 3.6% (95% CI, 2.0%-5.2%) for pediatric studies, and 17.3% (95% CI, 9.8-24.7) for refractory SE studies, with very high between-study heterogeneity. We found no evidence of a change in prognosis over time nor by the definition of SE used. Conclusions and Relevance The mortality of convulsive SE is higher in adults than in children and there was no evidence for improved survival over time. Although there are many explanations for these findings, they can be explained by aetiology of SE being the major determinant of mortality. However, there are potential confounders, including differences in case ascertainment and study heterogeneity. This meta-analysis highlights the need for strict international guidelines for the study of this condition.

Abstract
PURPOSE This randomized control study was conducted to compare the efficacy of sodium valproate (SVP) and levetiracetam (LEV) following initial intravenous lorazepam in elderly patients (age: >60years) with generalized convulsive status epilepticus (GCSE) and to identify predictors of poor seizure control. METHODS A total of 118 patients (mean age: 67.5 ± 7.5 years, M:F = 1.6:1), who had presented with GCSE were randomized into the SVP or LEV treatment arms. All patients received initial intravenous lorazepam (0.1 mg/kg) followed by one of the two antiepileptic drugs (AEDs), parenteral SVP (20-25 mg/kg) or LEV (20-25 mg/kg). Those who failed to achieve control with the initial AED, were crossed over to receive the other AED. One-hundred patients (SVP = 50; LEV = 50) completed the study. RESULTS SE could be controlled with lorazepam and one of the AEDs (SVP or LEV) in 71.18% (84/118). Intention-to-treat analysis showed that the two groups did not differ significantly in terms of seizure control [SVP: 41/60 (68.3%); LEV: 43/58 (74.1%), p = 0.486]. Of 100 patients who completed the study, seizure control was achieved in 38/50(76%) in the SVP and 43/50(86%) in the LEV group (p = 0.202). After crossing over to the second AED, SE could be controlled in an additional in 50% (6/12) in SVP (+LEV) group and in 14.3% (1/7) in LEV (+SVP) group. Overall, after the second AED, seizure control was achieved in 77.1% (91/118). Higher STESS was associated with poor therapeutic response (p = 0.049). CONCLUSIONS The efficacy of SVP and LEV following initial lorazepam in controlling GCSE in elderly population was comparable, hence the choice of AED could be individualized.

Abstract
Despite being first described over 50 years ago, periodic discharges continue to generate controversy as to whether they are always, sometimes, or never "ictal." Investigators and clinicians have proposed adjunctive markers to help clarify this distinction-in particular measures of perfusion and metabolism. Here, we review the growing number of neuroimaging studies using Fluorodeoxyglucose-PET, MRI diffusion, Magnetic resonance perfusion, Single Photon Emission Computed Tomography, and Magnetoencepgalography to gain further insight into the physiology and clinical significance of periodic discharges. To date, however, no definitive consensus exists regarding the features of periodic discharges that warrant treatment intensification. However, an emerging consilience among neuroimaging modalities suggests that periodic discharges can induce a hyperexcitatory state with associated hypermetabolism and hyperperfusion, which may result in local metabolic failure.

Abstract
PURPOSE To evaluate the clinical features and prognosis of status epilepticus (SE) in patients above 70 years old. METHODS Retrospective analysis of all patients ≥70 years old with SE registered prospectively during 4 years. Follow-up after discharge was performed. RESULTS Ninety patients were evaluated. Acute symptomatic etiology was the most prevalent. The mean number of antiepileptic drugs (AEDs) used was 2.7 ± 1.2, and 21% of the patients required sedation. A poor outcome was considered when death (31.1%) or developing of new neurological impairment at discharge (32.2%) occurred. After multivariate analysis, four variables predicted a poor outcome: acute symptomatic etiology (OR: 6.320; 95% CI: 1.976-20.217; P = .002), focal motor SE type (OR: 9.089; 95% CI: 2.482-33.283; P = .001), level of consciousness (OR: 4.596; 95% CI: 1.903-11.098; P = .001), and SE duration >12 hours (OR: 3.763; 95% CI: 1.130-12.530; P = .031). Independent predictive factors of mortality were SE duration >12 hours (OR: 4.306; 95% CI: 1.044-17.757; P = .043), modified Status Epilepticus Severity Score (mSTESS) (OR: 2.216; 95% CI: 1.313-3.740; P = .003), and development of complications (OR: 3.334; 95% CI: 1.004-11.070, P = .049). Considering long-term mortality, age (HR 1.036; 95% CI 1.001-1.071; P = .044), a potentially fatal underlying cause (HR 2.609; 95% CI 1.497- 4.548; P = .001), and mSTESS score >4 (HR 1.485; 95% CI 1.158-1.903; P = .002) remained as predictive factors. There was no association between sedation and the number of AEDs used with outcome at discharge or long-term mortality (P > .05). CONCLUSIONS SE above 70 years old has a high morbimortality. Prognosis is not related to treatment aggressiveness.
