Risk factors for super-refractory and mortality in generalized convulsive status epilepticus: a 10-year retrospective cohort study. Ther Adv Neurol Disord 2023; 16:17562864231214846. [PMID: 38152090 PMCID: PMC10752052 DOI: 10.1177/17562864231214846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Accepted: 11/01/2023] [Indexed: 12/29/2023] Open
Abstract
Background Generalized convulsive status epilepticus (GCSE) is one of the most challenging life-threatening neurological emergencies. If GCSE becomes super-refractory, it is associated with significant mortality. Although aggressive management of prolonged status epilepticus was conducted, the mortality has not decreased since the late 1990s. Objectives The present study aimed to explore the risk factors for progression to super-refractory in patients with generalized convulsive status epilepticus (GCSE). Moreover, we illustrated the risk factors for mortality in GCSE patients. Design An observational retrospective cohort study. Methods We conducted a retrospective study of patients with GCSE admitted to our neurocritical unit, in Guangzhou, China, from October 2010 to February 2021. The data of sociodemographic information, etiology, laboratory results, treatment, and prognosis were collected and analyzed. Results A total of 106 patients were enrolled; 51 (48%) of them developed super-refractory status epilepticus (SRSE). Multivariate logistic regression analysis demonstrated that patients with autoimmune encephalitis (p = 0.015) and intracranial infection (p = 0.019) are likely to progress to SRSE. The in-hospital mortality was 11.8% and 9.1% for patients in the SRSE and non-SRSE groups, respectively (p = 0.652). Multivariate logistic regression analysis showed that neutrophil-to-lymphocyte ratios (NLR) at admission were independently associated with in-hospital mortality. Up to 31.4% of SRSE patients and 29.1% of non-SRSE patients died within 6 months after discharge (p = 0.798). Multivariate logistic regression analysis showed that plasma exchange (PE) was a protective factor for 6-month mortality. A high NLR at discharge was a risk factor for 6-month mortality. Conclusion In the current study, about 48% of GCSE patients progressed to SRSE. Regarding etiology, autoimmune encephalitis or intracranial infection was prone to SRSE. No significant differences were observed in the in-hospital and 6-month mortality between SRSE and non-SRSE groups. Multivariate logistic regression analysis showed that NLR at admission and discharge was an independent predictor of in-hospital and 6-month mortality, respectively. Moreover, PE significantly reduced the 6-month mortality.

Abstract
In this study, we report on a case of probable sporadic Creutzfeldt-Jakob disease (sCJD) diagnosed after a difficult course of status epilepticus (SE) in a patient with poststroke epilepsy. The patient was admitted with progressive cognitive decline and convulsive SE; therefore, it was initially thought that the patient had developed SE due to nonadherence to antiseizure medication (ASM) use, but despite treatment with ASMs after admission, no improvement was noted in consciousness disturbance or lateralized periodic discharges (LPDs) on electroencephalogram (EEG) examination. After a refractory course, the progression of LPDs to generalized periodic discharges (GPDs) on EEG and abnormal magnetic resonance imaging (MRI) findings met the diagnostic criteria of sCJD. Even if the patient had epilepsy, such as poststroke epilepsy, as in this case, it is essential to consider other underlying causes, including CJD in cases of superrefractory SE.

Abstract
Background Long-term sequelae of the new onset refractory status epilepticus (NORSE) include the development of epilepsy, cognitive deficits, and behavioral disturbances. The prevalence of these complications has been previously highlighted in case reports and case series: however, their full scope has not been comprehensively assessed. Methods We conducted a systematic review of the literature (PROSPERO ID CRD42022361142) regarding neurological and functional outcomes of NORSE at 30 days or longer following discharge from the hospital. A systematic review protocol was developed using guidance from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results Of the 1,602 records for unique publications, 33 reports on adults and 52 reports on children met our inclusion criteria. They contained the description of 280 adults and 587 children of whom only 75.7 and 85% of patients, respectively had data on long-term follow-up. The mean age of adult and pediatric patients was 34.3 and 7.9 years, respectively; and the longest duration of follow up were 11 and 20 years, respectively. Seizure outcomes received major attention and were highlighted for 93.4 and 96.6% of the adult and pediatric NORSE patients, respectively. Seizures remained medically refractory in 41.1% of adults and 57.7% of children, while seizure freedom was achieved in only 26 and 23.3% of these patients, respectively. The long-term cognitive outcome data was provided for just 10.4% of the adult patients. In contrast, cognitive health data were supplied for 68.9% of the described children of whom 31.9% were moderately or severely disabled. Long-term functional outcomes assessed with various standardized scales were reported in 62.2 and 25.5% of the adults and children, respectively with majority of patients not being able to return to a pre-morbid level of functioning. New onset psychiatric disorders were reported in 3.3% of adults and 11.2% of children recovering from NORSE. Conclusion These findings concur with previous observations that the majority of adult and pediatric patients continue to experience recurrent seizures and suffer from refractory epilepsy. Moderate to severe cognitive disability, loss of functional independence, and psychiatric disorders represent a hallmark of chronic NORSE signifying the major public health importance of this disorder.

Abstract
BACKGROUND Induction of ketosis by manipulation of nutrition intake has been proposed as an adjunctive treatment for super-refractory status epilepticus (SRSE). However, the classical 4:1 ketogenic ratio may not meet the nutrition needs, specifically protein for critically ill adults. The aim of this study was to analyze the outcomes of adults with SRSE who received a lower ketogenic ratio of 2:1 grams of fat to non-fat grams, including 20%-30% of energy from medium chain triglycerides. METHODS We reviewed patients aged ≥18 years with SRSE treated with ketogenic therapy between July 2015 and December 2020 at two quaternary teaching hospitals in Melbourne, Australia. Data collected from medical records included patient demographics, nutrition prescription, clinical outcomes, and ketogenic therapy-related complications. The primary outcome of the study was to assess tolerability of ketogenic therapy. RESULTS Twelve patients (female = 7) were treated with ketogenic therapy for SRSE. Patients received between 4 and 8 antiseizure medications and 1-5 anesthetic agents prior to commencement of ketogenic therapy. Blood beta-hydroxybutyrate concentrations were variable (median = 0.5 mmol/L, range: 0.0-6.1 mmol/L). SRSE resolved in 10 cases (83%) after a median of 9 days (range: 2-21 days) following commencement of ketogenic therapy. Ketogenic therapy-associated complications were reported in five patients, leading to cessation in two patients. CONCLUSION Despite the challenge in maintaining ketosis during critical illness, low ratio 2:1 ketogenic therapy incorporating medium chain triglycerides is tolerable for adults with SRSE. Further studies are required to determine the optimal timing, nutrition prescription and duration of ketogenic therapy for SRSE treatment.

Efficacy and safety of VNS therapy or continued medication management for treatment of adults with drug-resistant epilepsy: systematic review and meta-analysis. J Neurol 2022; 269:2874-2891. [PMID: 35034187 PMCID: PMC9119900 DOI: 10.1007/s00415-022-10967-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 01/05/2022] [Accepted: 01/06/2022] [Indexed: 11/30/2022]
Abstract
Vagus nerve stimulation (VNS) Therapy® is an adjunctive neurostimulation treatment for people with drug-resistant epilepsy (DRE) who are unwilling to undergo resective surgery, have had unsuccessful surgery or are unsuitable for surgery. A systematic review and meta-analysis were conducted to determine the treatment effects of VNS Therapy as an adjunct to anti-seizure medications (ASMs) for the management of adults with DRE. A literature search was performed in August 2020 of the Medline®, Medline® Epub Ahead of Print, Embase, and the Cochrane library databases. Outcomes examined included reduction in seizure frequency, seizure freedom, ASM load, discontinuations, and serious adverse events (SAEs). Comparators included best medical practice, ASMs, low-stimulation or sham VNS Therapy. Four RCTs and six comparative observational studies were identified for inclusion. Against comparators, individuals treated with VNS had a significantly better odds of experiencing a ≥ 50% reduction in seizure frequency (OR: 2.27 [95% CI 1.47, 3.51]; p = 0.0002), a ≥ 75% reduction in seizure frequency (OR: 3.56 [95% CI 1.59, 7.98]; p = 0.002) and a reduced risk for increased ASM load (risk ratio: 0.36 [95% CI 0.21, 0.62]; p = 0.0002). There was no difference in the odds of discontinuation or the rate of SAEs between VNS versus comparators. This meta-analysis demonstrated the benefits of VNS Therapy in people with DRE, which included improvement in seizure frequency without an increase in the rate of SAEs or discontinuations, thereby supporting the consideration of VNS Therapy for people who are not responding to ASMs and those unsuitable or unwilling to undergo surgery.

Abstract
OBJECTIVES To characterize the pediatric super-refractory status epilepticus population by describing treatment variability in super-refractory status epilepticus patients and comparing relevant clinical characteristics, including outcomes, between super-refractory status epilepticus, and nonsuper-refractory status epilepticus patients. DESIGN Retrospective cohort study with prospectively collected data between June 2011 and January 2019. SETTING Seventeen academic hospitals in the United States. PATIENTS We included patients 1 month to 21 years old presenting with convulsive refractory status epilepticus. We defined super-refractory status epilepticus as continuous or intermittent seizures lasting greater than or equal to 24 hours following initiation of continuous infusion and divided the cohort into super-refractory status epilepticus and nonsuper-refractory status epilepticus groups. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We identified 281 patients (157 males) with a median age of 4.1 years (1.3-9.5 yr), including 31 super-refractory status epilepticus patients. Compared with nonsuper-refractory status epilepticus group, super-refractory status epilepticus patients had delayed initiation of first nonbenzodiazepine-antiseizure medication (149 min [55-491.5 min] vs 62 min [33.3-120.8 min]; p = 0.030) and of continuous infusion (495 min [177.5-1,255 min] vs 150 min [90-318.5 min]; p = 0.003); prolonged seizure duration (120 hr [58-368 hr] vs 3 hr [1.4-5.9 hr]; p < 0.001) and length of ICU stay (17 d [9.5-40 d] vs [1.8-8.8 d]; p < 0.001); more medical complications (18/31 [58.1%] vs 55/250 [22.2%] patients; p < 0.001); lower return to baseline function (7/31 [22.6%] vs 182/250 [73.4%] patients; p < 0.001); and higher mortality (4/31 [12.9%] vs 5/250 [2%]; p = 0.010). Within the super-refractory status epilepticus group, status epilepticus resolution was attained with a single continuous infusion in 15 of 31 patients (48.4%), two in 10 of 31 (32.3%), and three or more in six of 31 (19.4%). Most super-refractory status epilepticus patients (30/31, 96.8%) received midazolam as first choice. About 17 of 31 patients (54.8%) received additional treatments. CONCLUSIONS Super-refractory status epilepticus patients had delayed initiation of nonbenzodiazepine antiseizure medication treatment, higher number of medical complications and mortality, and lower return to neurologic baseline than nonsuper-refractory status epilepticus patients, although these associations were not adjusted for potential confounders. Treatment approaches following the first continuous infusion were heterogeneous, reflecting limited information to guide clinical decision-making in super-refractory status epilepticus.

Abstract
PURPOSE We conducted this study to determine the clinical, electrophysiological and radiological predictors of outcome in Super Refractory Status Epilepticus (SRSE). METHODS Data of patients treated for SRSE between January 2000 and November 2019, archived prospectively in our SE registry were analyzed. Functional outcome was measured by Glasgow outcome score (GOS) at the time of hospital discharge and was divided into: good i.e. GOS ≥ 3 and bad outcome i.e. GOS < 3. The predictors of outcome were determined using appropriate statistical tests by univariate and multivariate analysis, p < 0.05 was considered as statistically significant. RESULTS Of the 384 patients with status epilepticus (SE) identified during the study, 28 (8%) were diagnosed as SRSE and were included in the final analysis. Acute symptomatic SE comprising 15 (53.6%) patients was the most common etiology of SRSE. Thirteen patients (three patients with viral encephalitis and 10 patients with clinically possible autoimmune encephalitis) had New Onset Refractory Status Epilepticus (NORSE) like clinical presentation.12 patients (42.9%) had good outcome and 16 patients (57.1%) had bad outcome. Multivariate logistic regression analysis showed that independent predictors of poor outcome were: duration of ICU stay (p < 0.001); EEG findings such as non-convulsive SE in coma (0.032), spontaneous burst suppression (0.001) and postictal diffuse attenuation (<0.001); delay in starting anesthesia (0.002); and delay in starting immunotherapy in NORSE due to autoimmune encephalitis (0.002). CONCLUSION We could determine independent therapeutic and electrophysiological prognostic factors for SRSE. Early initiation of treatment and stringent management of these factors especially in an younger age-group, aided by continuous EEG monitoring and a thorough etiological work-up can result in good outcomes in more than one-third of cases.

Abstract
PURPOSE We attempted to determine the nationwide in-hospital mortality rate in people with status epilepticus (SE) in China. METHODS Using the database of the Chinese Hospital Quality Monitoring System (HQMS), we identified people hospitalised from 2013 to 2017 with an ICD-10 code G41 for SE as the primary diagnosis. HQMS was developed by the National Health Commission of the People's Republic of China. Demographics, outcomes at discharge, and financial information were extracted automatically from the medical records. RESULTS We identified 29,031 cases with SE as the primary diagnosis from 585 tertiary centres during the five-year period. Among those included, there was a preponderance of men (61 %), and the mean age was 40.4 ± 25.2 years (range: 0-98). The in-hospital mortality rate was 1.46 % over the whole time period, while the overall mortality ranged from 1.80 % in 2013 to 1.20 % in 2017. The mean cost of treatment was 14517.81 RMB ($ 2147.92) per individual, and the mean duration of hospital stay was 9.25 days. CONCLUSION We provide an overview of mortality related to SE in China as the HQMS database covers a large number of cases of SE in China, making it one of the most efficient tools for mortality investigation. The use of electronic medical records in China creates several challenges and here we discuss lessons learned. The methodology will be improved and will be used in future studies.

Abstract
PURPOSE OF REVIEW Status epilepticus, refractory status epilepticus, and super-refractory status epilepticus can be life-threatening conditions. This article presents an overview of the three conditions and discusses their management and outcomes. RECENT FINDINGS Status epilepticus was previously defined as lasting for 30 minutes or longer but now is more often defined as lasting 5 minutes or longer. A variety of potential causes exist for status epilepticus, refractory status epilepticus, and super-refractory status epilepticus, but all three ultimately involve changes at the cellular and molecular level. Management of patients with status epilepticus generally requires several studies, with EEG of utmost importance given the pathophysiologic changes that can occur during the course of status epilepticus. Status epilepticus is treated with benzodiazepines as first-line antiepileptic drugs, followed by phenytoin, valproic acid, or levetiracetam. If status epilepticus does not resolve, these are followed by an IV anesthetic and then alternative therapies based on limited data/evidence, such as repetitive transcranial magnetic stimulation, therapeutic hypothermia, immunomodulatory agents, and the ketogenic diet. Scores have been developed to help predict the outcome of status epilepticus. Neurologic injury and outcome seem to worsen as the duration of status epilepticus increases, with outcomes generally worse in super-refractory status epilepticus compared to status epilepticus and sometimes also to refractory status epilepticus. SUMMARY Status epilepticus can be a life-threatening condition associated with multiple complications, including death, and can progress to refractory status epilepticus and super-refractory status epilepticus. More studies are needed to delineate the best management of these three entities.

Abstract
New-onset refractory status epilepticus (NORSE) is a clinical presentation, not a specific diagnosis, in a patient without active epilepsy or other preexisting relevant neurologic disorder, with new onset of refractory status epilepticus (RSE) that does not resolve after 2 or more rescue medications, without a clear acute or active structural, toxic, or metabolic cause. Febrile infection-related epilepsy syndrome is a subset of NORSE in which fever began at least 24 hours prior to the RSE. Both terms apply to all age groups. Until recently, NORSE was a poorly recognized entity without a consistent definition or approach to care. We review the current state of knowledge in NORSE and propose a roadmap for future collaborative research. Research investigating NORSE should prioritize the following 4 domains: (1) clinical features, etiology, and pathophysiology; (2) treatment; (3) adult and pediatric evaluation and management approaches; and (4) public advocacy, professional education, and family support. We consider international collaboration and multicenter research crucial in achieving these goals.

Abstract
Objective: Status epilepticus (SE) is one of the most critical symptoms of encephalitis. Studies on early predictions of progression to super-refractory status epilepticus (SRSE) and poor outcome in SE due to acute encephalitis are scarce. We aimed to investigate the values of neuroimaging and continuous electroencephalogram (EEG) in the multimodal prediction. Methods: Consecutive patients with convulsive SE due to acute encephalitis were included in this study. Demographics, clinical features, neuro-imaging characteristics, medical interventions, and anti-epileptic treatment responses were collected. All the patients had EEG monitoring for at least 24 h. We determined the early predictors of SRSE and prognostic factors of 3-month outcome using multivariate logistic regression analyses. Results: From March 2008 to February 2018, 570 patients with acute encephalitis were admitted to neurological intensive care unit (N-ICU) of Xijing hospital. Among them, a total of 94 patients with SE were included in this study. The percentage of non-SRSE and SRSE were 76.6 and 23.4%. Cortical or hippocampal abnormality on neuroimaging (p = 0.002, OR 20.55, 95% CI 3.16-133.46) and END-IT score (p < 0.001, OR 4.07, 95% CI 1.91-8.67) were independent predictors of the progression to SRSE. At 3 months after N-ICU discharge, 56 (59.6%) patients attained good outcomes, and 38 (40.4%) patients had poor outcomes. The recurrence of clinical or EEG seizures within 2 h after the infusion rate of a single anesthetic drug >50% proposed maximal dose (p = 0.044, OR 4.52, 95% CI 1.04-19.68), tracheal intubation (p = 0.011, OR 4.99, 95% CI 1.37-11.69) and emergency resuscitation (p = 0.040, OR 9.80, 95% 1.11-86.47) predicted poor functional outcome. Interpretation: Initial neuro-imaging findings assist early identification of the progression to SRSE. Continuous EEG monitoring contributes to outcome prediction in SE due to acute encephalitis.

Abstract
Background Super-refractory status epilepticus (SRSE) is a critical neurological condition with a high mortality rate. There are only limited data to direct the treatment in SRSE, and surgery has been reported to successfully stop SRSE. We present a case of recurrent SRSE treated with urgent right temporal lobectomy in a right-handed woman which potentially saved her life but resulted in crossed sensory aphasia. Case Description A 61-year-old woman with a recent episode of prolonged focal SRSE due to right frontotemporal meningioma and hyperkalemia was admitted for recurrence of seizures that evolved to SRSE despite aggressive treatment with multiple fosphenytoin antiepileptic drugs (AEDs) and anesthetics. The patient underwent a right temporal lobectomy to remove the encephalomalacic and gliotic tissue around the meningioma that had been resected during a previous admission. Postoperatively the patient had a protracted course with modest improvement after stepwise reduction in her AEDs; however, her recovery unveiled a severe crossed aphasia. Conclusion Resective surgery is an effective treatment option in the treatment of SRSE, although the recovery period can be protracted. Crossed aphasia after right temporal lobectomy should be considered in patients where it is not possible to complete a presurgical evaluation of higher cortical functions.

Abstract
OBJECTIVE Status epilepticus (SE) is a neurological emergency that may cause severe neurological deficiency and even death. The aim of this study was to analyze the clinical characteristics and prognosis of SE in northeast China. Additionally, the etiology and classification are discussed. MATERIALS AND METHODS We retrospectively collected the clinical profiles of patients diagnosed with SE in the Epilepsy Center of Jilin University between January 2011 and May 2015. The causes and clinical courses were investigated. The individuals were followed up by visit or telephone, and the prognoses were analyzed. RESULTS A total of 223 patients with SE were enrolled, including 134 cases with non-refractory SE (NRSE) and 89 cases with refractory or super-refractory SE (RSE/SRSE). Fifteen patients died during hospitalization, yielding a mortality of 6.73%; 11 of them succumbed to multiple organ dysfunction syndrome (MODS). Statistical analysis showed significant differences in age, family history of epilepsy, and the incidence of non-convulsive SE (NCSE) between the NRSE group and RSE/SRSE group (p < 0.05). We found no significant differences in the causes of SE (central nervous system infection, autoimmune encephalitis, and epilepsy) between these 2 groups. CONCLUSION In northeast China, SE is associated with relatively lower mortality, and MODS is the major cause of death. Older age and NCSE are risk factors predicting potential progression to RSE. Central nervous system infection, autoimmune encephalitis, and epilepsy were common causes of SE, but there was no significant association between any of these causes and the occurrence of RSE.

Abstract
PURPOSE This study investigated the predictive factors for progression from seizure-related endosulfan poisoning to status epilepticus (SE) and refractory SE (RSE). This study also investigated delayed neurologic sequelae in seizure-related endosulfan poisoning. METHODS This retrospective, observational case series consisted of 73 patients who developed at least one seizure after endosulfan ingestion. RESULTS The progression rates from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE were 78.1% and 54.4%, respectively. The SE and RSE fatality rates were 19.2% and 41.9%, respectively. No patients reported the development of delayed neurological sequelae at least six months after discharge. Glasgow coma scale (GCS) score were identified as an independent factor for progression from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE. Lorazepam administration was independently associated with preventing progression from SE-related endosulfan poisoning to RSE. CONCLUSION Seizure-related endosulfan poisoning had higher progression rates to SE and RSE and higher fatality rates than other drug-induced seizures. However, delayed neurologic sequelae after discharge were not demonstrated. Due to the high progression rates from seizure-related endosulfan poisoning to SE and RSE and the absence of an established treatment for SE-related endosulfan poisoning, physicians should aggressively treat patients who experience a seizure after endosulfan poisoning and who present with decreased GCS score. Lorazepam should be considered a first-line anti-epileptic drug for controlling seizures in patients with endosulfan poisoning.

Abstract
OBJECTIVE To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients. METHODS The Premier Hospital Database was utilized to estimate the number of SRSE cases based on hospital discharges during 2012. Discharges were classified as SRSE cases based on an algorithm using seizure-related International Classification of Diseases-9 (ICD-9) codes, Intensive Care Unit (ICU) length of stay (LOS), and treatment protocols (e.g. benzodiazepines, anti-epileptic drugs (AEDs), and ventilator use). Secondary analyses were conducted using more restrictive algorithms for SRSE. RESULTS A total of 6,325 hospital discharges were classified as SRSE cases from a total of 5,300,000 hospital discharges. Applying a weighting based on hospital characteristics and 2012 US demographics, this projected to an estimated 41,156 cases of SRSE in the US during 2012, an estimated incidence rate of ∼13/100,000 annually for SRSE in the US. Secondary analyses using stricter SRSE algorithms resulted in estimated incidence rates of ∼11/100,000 and 8/100,000 annually. The mean LOS for SRSE hospitalizations was 16.5 days (median =11; interquartile range [IQR] = 6-20), and the mean ICU LOS was 9.3 days (median =6; IQR =3-12). The mean cost of an SRSE hospitalization was $51,247 (median = $33,294; 95% CI = $49,634-$52,861). LIMITATIONS The analysis uses ICD-9 diagnostic codes and claims information, and there are inherent limitations in any methodology based on treatment protocol, which created challenges in distinguishing with complete accuracy between SRSE, RSE, and SE on the basis of care patterns in the database. CONCLUSION SRSE is associated with high mortality and morbidity, which place a high burden on healthcare resources. Projections based upon the findings of this study suggest an estimated 25,821-41,959 cases of SRSE may occur in the US each year, but more in-depth studies are required.

Abstract
Critically ill patients with seizures are either admitted to the intensive care unit because of uncontrolled seizures requiring aggressive treatment or are admitted for other reasons and develop seizures secondarily. These patients may have multiorgan failure and severe metabolic and electrolyte disarrangements, and may require complex medication regimens and interventions. Seizures can be seen as a result of an acute systemic illness, a primary neurologic pathology, or a medication side-effect and can present in a wide array of symptoms from convulsive activity, subtle twitching, to lethargy. In this population, untreated isolated seizures can quickly escalate to generalized convulsive status epilepticus or, more frequently, nonconvulsive status epileptics, which is associated with a high morbidity and mortality. Status epilepticus (SE) arises from a failure of inhibitory mechanisms and an enhancement of excitatory pathways causing permanent neuronal injury and other systemic sequelae. Carrying a high 30-day mortality rate, SE can be very difficult to treat in this complex setting, and a portion of these patients will become refractory, requiring narcotics and anesthetic medications. The most significant factor in successfully treating status epilepticus is initiating antiepileptic drugs as soon as possible, thus attentiveness and recognition of this disease are critical.

Abstract
OBJECTIVE While status epilepticus (SE) persisting after two antiseizure agents is called refractory (RSE), super-refractory status epilepticus (SRSE) defines SE continuing after general anaesthesia. Its prevalence and related clinical profiles have received limited attention, and most studies were restricted to intensive care facilities. We therefore aimed at describing RSE and SRSE frequencies and identifying associated clinical variables. METHODS Between 2006 and 2015, consecutive adult SE episodes were prospectively recorded in a registry. Occurrence of RSE and SRSE and their relationship to clinical variables of interest, including outcome, were analysed. RESULTS Of 804 SE episodes, 268 (33.3%) were RSE and 33 (4%) SRSE. Coma induction for SE treatment occurred in 79 (9.8%) episodes. Severe consciousness impairment (OR 1.67; 95% CI 1.24-2.46; P = 0.001), increasing age (OR 1.01, 95% CI 1.01-1.02), and lack of remote symptomatic SE aetiology (OR 0.48; 95% CI 0.32-0.72) were independently associated with RSE, while severe consciousness impairment (OR 4.26; 95% CI 1.44-12.60) and younger age (OR 0.96; 95% CI 0.95-0.99) correlated with SRSE; however, most SRSE episodes were not predicted by these variables. Mortality was 15.5% overall, higher in RSE (24.5%) and SRSE (37.9%) than in non-refractory SE (9.8%) (P < 0.001). SIGNIFICANCE Super-refractory status epilepticus appears clearly less prevalent in this cohort than previously reported, probably as it is not restricted to intensive care unit. SRSE emerges in younger patients with marked consciousness impairment, pointing to the underlying severe clinical background, but these variables do not predict most SRSE developments. There is currently a knowledge gap for prediction of SRSE occurrence that needs to be filled.
