Abstract
Management of severe (drug-resistant) epilepsy and epilepsy in other serious illnesses is multidimensional and requires consideration of both physical symptoms and psychosocial distress that require individualized treatment. Palliative care offers a holistic approach to disease that focuses on all dimensions of suffering to maintain quality of life. Integration of a palliative care mind- and skillset in the management of severe epilepsy and epilepsy in other serious illnesses can provide person-centered care and support for families and caregivers.

Abstract
OBJECTIVES Although in epilepsy patients the likelihood of becoming seizure-free decreases substantially with each unsuccessful treatment, to our knowledge this has been poorly investigated in status epilepticus (SE). We aimed to evaluate the proportion of SE cessation and functional outcome after successive treatment steps. METHODS We conducted a post hoc analysis of a prospective, observational, multicenter cohort (Sustained Effort Network for treatment of Status Epilepticus [SENSE]), in which 1049 incident adult SE episodes were prospectively recorded at nine European centers. We analyzed 996 SE episodes without coma induction before the third treatment step. Rates of SE cessation, mortality (in ongoing SE or after SE control), and favorable functional outcome (assessed with modified Rankin scale) were evaluated after each step. RESULTS SE was treated successfully in 838 patients (84.1%), 147 (14.8%) had a fatal outcome (36% of them died while still in SE), and 11 patients were transferred to palliative care while still in SE. Patients were treated with a median of three treatment steps (range 1-13), with 540 (54.2%) receiving more than two steps (refractory SE [RSE]) and 95 (9.5%) more than five steps. SE was controlled after the first two steps in 45%, with an additional 21% treated after the third, and 14% after the fourth step. Likelihood of SE cessation (p < 0.001), survival (p = 0.003), and reaching good functional outcome (p < 0.001) decreased significantly between the first two treatment lines and the third, especially in patients not experiencing generalized convulsive SE, but remained relatively stable afterwards. SIGNIFICANCE The significant worsening of SE prognosis after the second step clinically supports the concept of RSE. However, and differing from findings in human epilepsy, RSE remains treatable in about one third of patients, even after several failed treatment steps. Clinical judgment remains essential to determine the aggressiveness and duration of SE treatment, and to avoid premature treatment cessation in patients with SE.

Abstract
BACKGROUND AND OBJECTIVES Benzodiazepines are the first treatment line in status epilepticus (SE). Despite their well-established benefit, benzodiazepines are frequently underdosed with potential detrimental consequences. In some European countries, clonazepam (CLZ) is commonly used as the first line treatment. The aim of this study was to explore the correlation between CLZ loading doses and SE outcome. METHODS This study included a retrospective analysis of a prospective registry in Lausanne, Switzerland (CHUV Lausanne University Hospital), including all SE episodes treated between February 2016 and February 2021. Only adults (> 16 years old) were included with CLZ used as the first treatment line. Post-anoxic SE were excluded because of significant differences in physiopathology and prognosis. Patient characteristics, SE features, the validated SE severity score (STESS), and treatment characteristics were prospectively recorded. We considered loading doses of 0.015 mg/kg or higher (following commonly recommended loading doses) as high doses. We analyzed outcome in terms of number of treatment lines after the CLZ, proportion of refractory episodes, intubation for airways protection, intubation for SE treatment, and mortality. We performed univariable analyses to investigate the association between loading doses and clinical response. A multivariable stepwise backward binary logistic regression was applied for adjusting for potential confounders. Multivariable linear regression was similarly used to analyze CLZ dose as a continuous variable. RESULTS We collected 251 SE episodes in 225 adult patients. Median CLZ loading dose was 0.010 mg/kg. CLZ high doses were used in 21.9% of SE episodes (in 43.8% for > 80% of the high dose). Thirteen percent of patients with SE were intubated for airways control, while intubation was needed in 12.7% for SE treatment. High CLZ loading doses were independently associated with younger age (median 62 versus 68 years old, p = 0.002), lesser weight (65 kg versus 75 kg, p = 0.001) and more frequent intubation for airways protection (23% vs 11%, p = 0.013), but differing CLZ dose was not associated with any outcome parameter. CONCLUSION CLZ high doses were more frequently used for SE treatment in younger patients with healthy weight and were more often associated with intubation for airways protection, probably as an adverse event. Varying CLZ dose did not alter outcome in SE, raising the possibility that commonly recommended doses are above what is needed, at least in some patients. Our results suggest that CLZ doses in SE may be individualized depending on the clinical setting.

Abstract
INTRODUCTION Status epilepticus (SE) is a neurological emergency associated with high mortality if not identified and treated promptly. For the emergent treatment of SE, the recommended intravenous (IV) lorazepam dose is 0.1 mg/kg/dose, up to a maximum of 4 mg. It has been shown that lorazepam is commonly under dosed in SE, but there is conflicting data on whether this has a negative impact on patient outcomes. This study assessed any dose less than 4 mg to help identify the effects of under dosing lorazepam in SE. METHODS This was a retrospective cohort study of patients admitted to a quaternary health system between October 1, 2017 and September 30, 2019 that experienced SE and were initially treated with IV lorazepam. Patients were divided into two cohorts, less than 4 mg or 4 mg, based on the initial one-time dose of lorazepam received. The primary outcome was the proportion of patients that progressed to refractory status epilepticus (RSE) that received an initial IV lorazepam dose of 4 mg compared to less than 4 mg for the treatment of SE. Secondary outcomes evaluated include length of stay, mortality, time in SE, number of seizures, cumulative lorazepam dose prior to urgent therapy, number of lorazepam doses prior to urgent therapy, time to urgent therapy, appropriately dosed urgent therapy, and number of antiepileptic drugs given in SE. RESULTS One hundred twenty patients were included in this study (107 patients received less than 4 mg and 13 patients received 4 mg). All patients included in the study were greater than 40 kg. The primary outcome of progression to RSE was observed in a significantly greater proportion of patients in the less than 4 mg group compared to the 4 mg group (93 [87%] vs. 8 [62%], p = 0.03). There was no difference in hospital or intensive care unit length of stay. However, there was an increased rate of in-hospital mortality in patients who received 4 mg compared to less than 4 mg (5 [39%] vs. 12[11%], p = 0.02). DISCUSSION The majority of patients in the study received less than the recommended dose of IV lorazepam for SE. Patients who received less than 4 mg experienced an increased progression to RSE, which supports current guideline recommended dosing. While there was an increased rate of mortality in patients who received 4 mg compared to less than 4 mg, time in SE was prolonged in the patient population and severity of illness was only available for a limited number of patients included.

Abstract
Status epilepticus (SE) is one of the leading life-threatening neurological emergencies in the elderly population, with significant morbidity and mortality. SE presents unique diagnostic and therapeutic challenges in the older population given overlap with other causes of encephalopathy, complicating diagnosis, and the common occurrence of multiple comorbid diseases complicates treatment. First-line therapy involves the use of rescue benzodiazepine in the form of intravenous lorazepam or diazepam, intramuscular or intranasal midazolam and rectal diazepam. Second-line therapies include parenteral levetiracetam, fosphenytoin, valproate and lacosamide, and underlying comorbidities guide the choice of appropriate medication, while third-line therapies may be influenced by the patient's code status as well as the cause and type of SE. The standard of care for convulsive SE is treatment with an intravenous anesthetic, including midazolam, propofol, ketamine and pentobarbital. There is currently limited evidence guiding appropriate therapy in patients failing third-line therapies. Adjunctive strategies may include immunomodulatory treatments, non-pharmacological strategies such as ketogenic diet, neuromodulation therapies and surgery in select cases. Surrogate decision makers should be updated early and often in refractory episodes of SE and informed of the high morbidity and mortality associated with the disease as well as the high probability of subsequent epilepsy among survivors.

Abstract
OBJECTIVE In patients with status epilepticus (SE), the clinical significance of ictal changes on magnetic resonance imaging (MRI) is insufficiently understood. We here studied whether the presence of ictal MRI changes was associated with neurological deterioration at discharge. METHODS The retrospective cohort comprised all identifiable patients treated at Odense University Hospital in the period 2008-2017. All amenable MRIs were systemically screened for ictal changes. Patient demographics, electroencephalography, seizure characteristics, treatment, and SE duration were assessed. Neurological status was estimated before and after SE. The predefined endpoint was the association of neurological deterioration and ictal MRI changes. RESULTS Of 261 eligible patients, 101 received at least one MRI during SE or within 7 days after cessation; 43.6% (44/101) had SE due to non- or less brain-damaging etiologies. Patients who received MRI had a longer duration of SE, less frequently had a history of epilepsy, and were more likely to have SE due to unknown causes. Basic characteristics (including electroencephalographic features defined by the Salzburg criteria) did not differ between patients with (n = 20) and without (n = 81) ictal MRI changes. Timing of MRI was important; postictal changes were rare within the first 24 h and hardly seen >5 days after cessation of SE. Ictal MRI changes were associated with a higher risk of neurological deterioration at discharge irrespective of etiology. Furthermore, they were associated with a longer duration of SE and higher long-term mortality that reached statistical significance in patients with non- or less brain-damaging etiologies. SIGNIFICANCE In this retrospective cohort, ictal changes on MRI were associated with a higher risk of neurological deterioration at discharge and, possibly, with a longer duration of SE and poorer survival.

Abstract
Super-refractory status epilepticus (SRSE) is a life-threatening condition characterized by the persistence or recurrence of seizures despite the use of first- and second-line antiepileptic drugs and the continuous infusion of anesthetics for more than 24 hours. This has always been a challenge for the physician, given the high mortality and morbidity related to this condition. Unfortunately, there are currently no definitive data to guide the therapy, since most of the therapeutic approaches regarding SRSE come from anecdotal evidence. Here, we present a case report of long-persisting new-onset SRSE treated with unconventional therapies recently reported to be successful such as ketamine, ketogenic diet, and tocilizumab, that could have played an important role in the management of this patient. A review of the literature regarding those is also included. SRSE has been reported to have long hospital length of stay, with a small percentage of patients returning to baseline functional status. Moreover, recent evidence showed that functional and cognitive outcome could depend on seizure duration, so prolonged duration of epileptic activity with abnormalities on the magnetic resonance imaging (MRI) could be seen as a reason to discontinue treatment. However, despite many weeks of seizures and a noncomforting MRI, our patient was discharged with a good functional status.

Abstract
Quantitative burst suppression ratios (QBSR) represent depth of EEG suppression. Deeper QBSR on serial intermittent EEG did not affect survival in RSE. Non-suppressive continuous EEG effects on RSE mortality merits further research.
Objectives In refractory status epilepticus (RSE), the optimal degree of suppression (EEG burst suppression or merely suppressing seizures) remains unknown. Many centers lacking continuous EEG must default to serial intermittent recordings where uncertainty from lack of data may prompt more aggressive suppression. In this study, we sought to determine whether the quantitative burst suppression ratio (QBSR) from serial intermittent EEG recording is associated with RSE patient outcome. Methods We screened the EEG database to identify non-anoxic adult RSE patients for EEG and chart review. QBSR was calculated per 10-second EEG epoch as the percentage of time during which EEG amplitude was <3 µV. Patients who survived 1–3 months after discharge from ICU and hospital comprised the favorable group. Further to initial unadjusted univariate analysis of all pooled QBSR, we conducted multivariate analyses to account for individual patient confounders (“per-capita analysis”), uneven number of EEG recordings (“per-session analysis”), and uneven number of epochs (“per-epoch analysis”). We analyzed gender, anesthetic number, and adjusted status epilepticus severity score (aSTESS) as confounders. Results In 135,765 QBSR values over 160 EEG recordings (median 2.17 h every ≥24 h) from 17 patients on Propofol, Midazolam, and/or Ketamine, QBSR was deeper in the favorable group (p < 0.001) on initial unadjusted analysis. However, on adjusted multivariate analysis, there was consistently no association between QBSR and outcome. Higher aSTESS consistently associated with unfavorable outcome on per-capita (p = 0.033), per-session (p = 0.048) and per-epoch (p < 0.001) analyses. Greater maximal number of non-barbiturate anesthetic associated with favorable outcome on per-epoch analysis (p < 0.001). Conclusions There was no association between depth of EEG suppression using non-barbiturate anesthetic and RSE patient outcome based on QBSR from serial intermittent EEG. A per-epoch association between non-barbiturate anesthetic and favorable outcome suggests an effect from non-suppressive time-varying EEG content. Significance Targeting and following deeper burst suppression through non-barbiturate anesthetics on serial intermittent EEG monitoring of RSE is of limited utility.

Abstract
OBJECTIVE To determine the factors affecting mortality and disability in status epilepticus (SE) and to evaluate the prediction ability of the Status Epilepticus Severity Score (STESS) for disability and mortality. MATERIALS AND METHOD The demographic and clinical characteristics, prognosis and prognosis predictors of 72 patients who were diagnosed with SE between 2013 and 2018 were retrospectively evaluated. The STESS was used to predict prognosis, and the modified Rankin scale (mRS) was used to determine the disability at discharge. RESULTS The study population had a mean age of 45.4 ± 20.7, and it was found that mortality was 22.2% and acute symptomatic etiology played a 54.1% role in etiology. Advanced age, refractory SE or super-refractory SE, acute symptomatic etiology, and a history of epilepsy were related to mortality, symptomatic etiology (acute, progressive, remote), a history of hospitalization and epilepsy in intensive care or in other departments other than the neurology department were associated with disability. The sensitivity of STESS in predicting mortality was 100%, specificity was 69%, accuracy was 76.4%, positive predictive value (PPV) was 48.5%, and the negative predictive value (NPV) was 100%. The sensitivity of STESS in predicting mobilization during discharge was 55.6% with a 63.9% specificity and 59.7% accuracy, PPV was 60.6%, and NPV was 59%. CONCLUSION It was observed that STESS strongly predicts a good prognosis; however, it was not found to be useful in predicting motor disability during discharge. Thus, new studies should be conducted to predict and evaluate mobility in SE patients at discharge.

Abstract
OBJECTIVE To identify current evidence on the use of topiramate for refractory status epilepticus. METHODS We reviewed the literature to investigate the efficacy of topiramate in the treatment of refractory status epilepticus. The search terms used were "status epilepticus", "refractory", "treatment" and "topiramate". No restrictions were used. RESULTS The search yielded 487 articles that reported using topiramate as a treatment for refractory status epilepticus and its outcomes. Case reports, review articles, and animal experiments were excluded. After excluding duplicates and applying inclusion and exclusion criteria, nine studies were included for analyses. Descriptive and qualitative analyses were performed, and the results were as follows: response rates (defined as termination in-hospital until 72 hours after the administration of topiramate) varied from 27% to 100%. The mortality rate varied from 5.9% to 68%. Positive functional long-term outcomes, defined as discharge, back to baseline or rehabilitation, were documented by seven studies, and the rates ranged between 4% and 55%. Most studies reported no or mild adverse effects. CONCLUSION Topiramate was effective in terminating refractory status epilepticus, presented relatively low mortality and was well tolerated. Therefore, topiramate could be a good option as a third-line therapy for refractory status epilepticus, but further studies are necessary.

Abstract
There is still no optimal treatment for patients with severe anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis refractory to first-line therapy (including intravenous methylprednisolone [IVMP] and intravenous immunoglobulin [IVIG]). A small study has shown that immunoadsorption (IA) is effective in treating anti-NMDAR encephalitis. However, the effectiveness and safety of IA in the treatment of patients with refractory and severe anti-NMDAR encephalitis is not fully known. Four patients with severe anti-NMDAR encephalitis are reported, which were refractory to the first-line immunotherapy including IVMP and IVIG. Immunoadsorption is performed during the fulminant stage of disease, and the effectiveness and safety of IA are assessed. The modified Rankin Scale (mRS) is used to assess neurological conditions before and after IA. Four patients with the most severe form of anti-NMDAR encephalitis (two with teratoma and two with unknown origin) did not respond to one or more rounds of IVMP plus IVIG. They all required intensive care unit (ICU) support including long-term mechanical ventilation, and thus developed ICU-related complications. Gradual and steady improvement was observed after IA treatment. Except for mild hypotension in patient 1, no other adverse events were observed during IA. Two patients had good early overall recovery on discharge. The other two patients had a good outcome with mRS of 2 at the 12-month follow-up. This small case series suggests that IA may be an effective treatment option to accelerate the recovery of patients with severe and refractory anti-NMDAR encephalitis.

Abstract
BACKGROUND Timing in status epilepticus (SE) attention is probably the most relevant modifiable prognostic factor and may influence SE duration and prognosis. We aimed to describe the precise relationship between management timing, duration, and prognosis of SE. METHODS Observational longitudinal prospective study on a cohort of all patients diagnosed with SE admitted to our tertiary hospital from September 2017 to August 2019, with a 3-month follow-up. Univariate and multivariable analyses were performed to identify clinical and timing variables associated with SE duration and prognosis. RESULTS Eighty-three SE affecting 76 patients were included. Median age was 73 years, 61.4% were women, median baseline modified Rankin Scale (mRS) was 2, and 55.4% had prior epilepsy. In the out-of-hospital group (n = 50), median time to emergencies was 1.3 h and to hospital admission 2.8 h. In the global series, median time to neurologist was 4.3 h, and median time to therapy initiation was 4.5 h. These four times positively correlated with SE duration (all Spearman's rho coefficient >0.5, all p < .001). SE median duration was 24 h and was extended 1.2 h for each hour of treatment delay. A longer SE duration was associated with increased mortality and morbidity, both at hospital discharge and at 3-month follow-up (both p < .05). After 3 months, mortality was 30.1%, while recovery to baseline mRS occurred in 39.5%, with an overall median mRS of 4. CONCLUSIONS There were pervasive delays in all phases of SE attention, which conditioned a longer SE duration, and this led to increased long-term morbimortality.

Abstract
INTRODUCTION Tumor-associated status epilepticus (TASE) follows a relatively benign course compared with SE in the general population. Little, however, is known about associated prognostic factors. METHODS We conducted a prospective, observational study of all cases of TASE treated at a tertiary hospital in Barcelona, Spain between May 2011 and May 2019. We collected data on tumor and SE characteristics and baseline functional status and analyzed associations with outcomes at discharge and 1-year follow-up. RESULTS Eighty-two patients were studied; 58.5% (n = 48) had an aggressive tumor (glioblastoma or brain metastasis). Fifty-one patients (62.2%) had a favorable outcome at discharge compared with just 30 patients (25.8%) at 1-year follow-up. Fourteen patients (17.1%) died during hospitalization. Lateralized period discharges (LPDs) on the baseline electroencephalography (EEG), presence of metastasis, and SE severity were significantly associated with a worse outcome at discharge. The independent predictors of poor prognosis at 1-year follow-up were SE duration of at least 21 h, an aggressive brain tumor, and a nonsurgical treatment before SE onset. Lateralized period discharges, super-refractory SE, and an aggressive tumor type were independently associated with increased mortality. CONCLUSIONS Status epilepticus duration is the main modifiable factor associated with poor prognosis at 1-year follow-up. Accordingly, patients with TASE, like those with SE of any etiology, should receive early, aggressive treatment.

Abstract
Status epilepticus (SE) is a neurologic emergency with high morbidity and mortality. The assessment of a patient's prognosis is crucial in making treatment decisions. In this review, we discuss various markers that have been used to prognosticate SE in terms of recurrence, mortality, and functional outcome. These markers include demographic, clinical, electrophysiological, biochemical, and structural data. The heterogeneity of SE etiology and semiology renders development of prognostic markers challenging. Currently, prognostication in SE is limited to a few clinical scores. Future research should integrate clinical, genetic and epigenetic, metabolic, inflammatory, and structural biomarkers into prognostication models to approach "personalized medicine" in prognostication of outcomes after SE.

Abstract
Objective Refractory status epilepticus is a serious condition in which seizure continues despite use of two antiepileptic medications. Retrospective studies have shown that 29%‐43% of SE patients progress into RSE despite treatment. Mortality following RSE is high. We aimed to evaluate the predictors of outcome in patients with RSE at a tertiary care center. Methods Sixty‐eight consecutive patients with RSE who presented to our hospital between February 2018 and January 2020 were evaluated for outcome. Result In our study 28(41.2%), patients who failed to respond to first‐ and second‐line antiepileptic drug responded to the third‐line antiepileptic drug thus avoiding mechanical ventilation and intravenous anesthesia. Low GCS at admission (P < .001), need for mechanical ventilation and intravenous anesthesia (P = .018), and long duration of RSE before recovery (P = .035) were strongly associated with worse outcome. Duration of RSE before starting treatment (P = .147), previous history of seizure (P = .717), and age of the patient (P = .319) did not influence the outcome. Significance In our study, we prospectively evaluated patients with RSE and followed them for one month after discharge from the hospital. Unlike some of the previous studies, we identified an interesting finding whereby a significant proportion of the patients responded to the third‐line antiepileptic drug and thus avoiding the complications related to mechanical ventilation.

Abstract
OBJECTIVES To determine the causes of death in patients with status epilepticus. To analyze the relative contributions of seizure etiology, seizure refractoriness, use of mechanical ventilation, anesthetic drugs for seizure control, and medical complications to in-hospital and 90-day mortality, hospital length of stay, and discharge disposition. DESIGN Retrospective cohort. SETTING Single-center neuroscience ICU. PARTICIPANTS Patients with status epilepticus were identified by retrospective search of electronic database from January 1, 2011, to December 31, 2016. INTERVENTIONS Review of electronic medical records. MEASUREMENTS AND MAIN RESULTS Demographics, clinical characteristics, treatments, and outcomes were collected. Univariable and multivariable logistic regression analysis were used to determine whether the use of anesthetic drugs, mechanical ventilation, Status Epilepticus Severity Score, refractoriness of seizures, etiology of seizures, or medical complications were associated with in-hospital, 90-day mortality or discharge disposition. Among 244 patients with status epilepticus (mean age was 64 yr [interquartile range, 42-76], 55% male, median Status Epilepticus Severity Score 3 [interquartile range, 2-4]), 24 received anesthetic drug infusions for seizure control. In-hospital and 90-day mortality rates were 9.2% and 19.2%, respectively. Death was preceded by withdrawal of life-sustaining treatment in 19 patients (86.3%) and cardiac arrest in three (13.7%). Only Status Epilepticus Severity Score was associated with in-hospital and 90-day mortality, whereas the use of anesthetic drugs for seizure control, mechanical ventilation, medical complications, etiology, and refractoriness of seizures were not. Hospital length of stay was longer in patients with medical complications (p = 0.0091), refractory seizures (p = 0.0077), and in those who required anesthetic drugs for seizure control (p = 0.0035). Patients who had refractory seizures were less likely to be discharged home (odds ratio, 0.295; CI, 0.143-0.608; p = 0.0009). CONCLUSIONS In this cohort, death primarily resulted from the underlying neurologic disease and withdrawal of life-sustaining treatment and not from our treatment choices. Use of anesthetic drugs, medical complications, and mechanical ventilation were not associated with in-hospital and 90-day mortality.

Abstract
OBJECTIVE The aim of this study was to determine the factors affecting the mortality of refractory status epilepticus (RSE) in comparison with non-refractory status epilepticus (non-RSE). MATERIAL-METHOD Included in this retrospective study were 109 status epilepticus cases who were hospitalized in the neurological intensive care unit Katip Celebi University. Fifty-two were RSE and 57 were non-RSE. All clinical data were gathered from the hospital archives. Factors which may cause mortality were categorized for statistical analysis. RESULTS While elderly age, continuous clinical seizure activity, absence of former seizure, infection, prolonged stay of ICU, anesthesia, and cardiac comorbidity were significantly related to mortality in the RSE subgroup, potentially fatal accompanying diseases were significantly related to mortality in the non-RSE subgroup. No significant relationship was found between mortality and refractoriness. Multivariate analysis revealed that a Glasgow Coma Score (GCS) at presentation of 8 or lower was the independent predictor of mortality both in the general SE population (P = .017) and in the RSE subgroup (P = .007). Intubation (P = .011) and hypotension (P = .011) were the other independent predictors of mortality in the general SE population. No independent predictor of mortality was detected in the non-RSE subgroup. DISCUSSION/CONCLUSION Intubation, hypotension, and a low GCS at presentation could be the main factors which could alert clinicians of an increased risk of mortality in SE patients. Although non-RSE and RSE had similar rates of mortality in the ICU, the mortality-related factors of SE vary in the RSE and the non-RSE subgroups.

Abstract
Objective: The objective of this study is to identify risk factors for the development of refractory status epilepticus (RSE). Methods: This was an IRB-approved, retrospective case control study that included patients admitted with status epilepticus between August 1, 2014, and July 31, 2017. Cases were defined as those with RSE, and controls were those who did not develop RSE. A bivariate analysis was conducted comparing those with RSE and those without RSE. A stepwise logistic regression model was constructed predicting for progression to RSE. Risk factors for progression to RSE were extrapolated from this model. Results: A total of 184 patients met inclusion criteria for the study (99 controls and 49 cases). After adjusting for covariates in the logistic regression, patients with convulsive seizures had a lower odds of developing RSE (odds ratio [OR] = 0.375; 95% CI = 0.148 to 0.951; P = 0.0388). Treatment with benzodiazepines plus levetiracetam had a higher odds of developing RSE (OR = 3.804; 95% CI = 1.523 to 9.499; P = 0.0042). Conclusion and Relevance: This study found that patients with convulsive seizures had a lower odds of developing RSE. In addition, patients treated with benzodiazepines and levetiracetam had a higher odds of developing RSE. This information can be used to potentially identify patients at higher risk of developing RSE, so that treatment can be modified to reduce morbidity and mortality. These results may warrant further investigation into the effectiveness of levetiracetam as a first-line agent for the treatment of SE.

Abstract
AIM To evaluate the influence of adherence to treatment guidelines on outcomes in children presenting with status epilepticus (SE) using the Newborn and Paediatric Emergency Transport Service, New South Wales prospective registry. METHODS We reviewed the treatment of children with SE, transported by the Newborn And Paediatric Emergency Transport Service to a tertiary paediatric hospital, over 1 year. We evaluated variation in management from the New South Wales clinical practice guideline. RESULTS There was excessive administration of benzodiazepines (BZD) and a delay in administration of appropriate second-line treatment of status (median 45 min). There was excessive use of BZD, with five or more doses of BZD associated with significantly higher odds for intubation. CONCLUSION There is considerable scope to improve clinician compliance with the SE clinical practice guidelines.

Abstract
BACKGROUND Status epilepticus (SE) is a life-threatening neurologic emergency, which requires prompt medical treatment. Little is known of the long-term survival of SE. The aim of this study was to investigate which factors influence 90 days and 1-year mortality after SE. MATERIALS AND METHODS This retrospective study includes all consecutive adult (>16 years) patients (N = 70) diagnosed with generalized convulsive SE (GCSE) in Helsinki University Central Hospital (HUCH) emergency department (ED) over 2 years. We defined specific factors including patient demographics, GCSE characteristics, treatment, complications, delays in treatment, and outcome at hospital discharge and determined their relation to 90 days and 1-year mortality after GCSE by using logistic regression models. Survival analyses at 1 year after GCSE were performed with Cox proportional hazards regression analysis. RESULTS In-hospital mortality was 7.1%. Mortality rate was 14.3% at 90 days and 24.3% at 1 year after GCSE. In the univariate logistic regression analysis, Status Epilepticus Severity Score > 4 (STESS) (ODDS = 7.30, p = 0.012), worse-than-baseline condition at hospital discharge (ODDS = 3.5, p = 0.006), long delays in attaining seizure freedom (ODDS = 2.2, p = 0.041), and consciousness (ODDS = 3.4, p = 0.014) were risk factors for mortality at 90 days whereas epilepsy (ODDS = 0.2, p = 0.014) and Glasgow Outcome Scale (GOS) >3 at hospital discharge (ODDS = 0.05, p = 0.006) were protective factors. Risk factors for mortality at 1 year were STESS >4 (ODDS = 5.1, p = 0.028), use of vasopressors (ODDS = 8.2, p = 0.049), and worse-than-baseline condition at discharge (ODDS = 7.8, p = 0.010) while GOS >3 (ODDS = 0.2, p = 0.005) was protective. The univariate survival analysis at 1 year confirmed the significant findings regarding parameters STESS >4 (Hazard ratio (HR) = 4.1, p = 0.009), worse-than-baseline condition (HR = 6.2, p = 0.015), GOS >3 (HR = 0.2, p = 0.004) at hospital discharge and epilepsy (HR = 0.4, p = 0.044). Additionally, diagnostic delay over 6 h (HR = 3.8, p = 0.022) and Complication Burden Index (CBI) as an ordinal variable (0-2, 3-6, >6) (HR = 2.7, p = 0.027) were predictive for mortality. In the multivariate survival analysis, STESS > 4 (HR = 5.1, p = 0.007), CBI (HR = 3.2, p = 0.025, ordinal variable), diagnostic delay over 6 h (HR = 7.2, p = 0.003), and worse-than-baseline condition at hospital discharge (HR = 5.8, p = 0.027) were all independent risk factors for mortality at 1 year. CONCLUSIONS Severe form of SE, delayed recognition of GCSE, high number of complications during treatment period, and poor condition at hospital discharge are all independent predictors of long-term mortality. Most of these factors are also associated with mortality at 90 days, though at that point, delays in treatment seem to have a greater impact on prognosis than at 1 year.

Abstract
In convulsive status epilepticus (SE), achieving seizure control within the first 1-2 hours after onset is a significant determinant of outcome. Treatment is also more likely to work and be cost effective the earlier it is given. Initial first aid measures should be accompanied by establishing intravenous access if possible and administering thiamine and glucose if required. Calling for help will support efficient management, and also the potential for video-recording the events. This can be done as a best interests investigation to inform later management, provided adequate steps to protect data are taken. There is high quality evidence supporting the use of benzodiazepines for initial treatment. Midazolam (buccal, intranasal or intramuscular) has the most evidence where there is no intravenous access, with the practical advantages of administration outweighing the slightly slower onset of action. Either lorazepam or diazepam are suitable IV agents. Speed of administration and adequate initial dosing are probably more important than choice of drug. Although only phenytoin (and its prodrug fosphenytoin) and phenobarbitone are licensed for established SE, a now considerable body of evidence and international consensus supports the utility of both levetiracetam and valproate as options in established status. Both also have the advantage of being well tolerated as maintenance treatment, and possibly a lower risk of serious adverse events. Two adequately powered randomized open studies in children have recently reported, supporting the use of levetiracetam as an alterantive to phenytoin. The results of a large double blind study also including valproate are also imminent, and together likely to change practice in benzodiazepine-resistant SE.

Abstract
Brucellosis is a common zoonotic infection caused by bacterial genus Brucella, a Gram-negative bacterium, and continued to be a health problem in endemic areas. Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is an autoimmune disease which can lead to status epilepticus. A 19-year-old male patient was referred to our hospital with status epilepticus. The diagnosis of brucellosis was confirmed about 2 weeks before. The brain magnetic resonance imaging was normal. Lumbar puncture was performed, and cerebral spinal fluid (CSF) was in normal limits. The patient was treated with antiepileptic, anti-brucellosis agents. Two weeks after discharge, the patient readmitted to hospital with status epilepticus again. Extensive workup was negative except that NMDAR antibodies were detected in serum and CSF. The diagnosis of anti-NMDAR encephalitis was established. Brucellosis as a triggering factor for NMDAR encephalitis should be considered.

Abstract
The incidence of seizure activity was 10%. Seizure activity was detected within the first 30 min in three of the five patients. Markers for patient selection for cEEG in neurosurgical patients are needed.
Objective To prospectively compare the diagnostic yields of standard EEG and continuous EEG (cEEG) monitoring for the diagnosis of non-convulsive status epilepticus (NCSE) in neurosurgical patients in the intensive care unit. Methods We included 50 consecutive patients with clinical suspicion of NCSE due to unexplained coma or subtle clinical phenomena such as discrete myoclonus. The initial 30-minute EEG recording and the following cEEG were analyzed separately for seizure activity. Data were collected on neurosurgical diagnosis, previous diagnosis of epilepsy, current medication, level of consciousness, and outcome at discharge from the neurosurgical department. Results Recurrent electrographic seizure activity was detected in five patients. This was within the first 30 mins for three patients and on the following cEEG for two patients. Antiepileptic treatment had been initiated in three of these patients. Most of the 50 patients had severe newly acquired neurological disability at discharge. Conclusions The prospective finding of a 10% seizure incidence was lower than reports from retrospective studies. Significance Use of cEEG led to detection of seizure activity in 2 of 50 patients (4%) and was thus a low-yield method in neurosurgical patients with suspicion of NCSE. Specific markers for patient selection for cEEG are needed.

Abstract
This study aimed to elucidate the therapeutic concentration range of phenobarbital (PB) for adults, as well as the influence of therapeutic plasma exchange (TPE) on plasma concentration of PB. We retrospectively reviewed consecutive patients diagnosed with refractory status epileptic (RSE) and treated with a bolus injection of PB as well as TPE, admitted to our neurocritical care unit from November 2015 to October 2016. Continuous electroencephalographic monitoring was performed routinely for these patients. TPE was performed using a continuous-flow cell separator. PB concentrations in the plasma and cerebrospinal fluid were measured by gas chromatography-mass spectrometer analysis before and after TPE. A total of seven patients were included; among these, one patient had RSE related to anti-N-methyl-D-aspartate receptor encephalitis, another patient had Hashimoto encephalopathy, and five patients had undetermined etiology. For patients with clinical and electrographic control (n=6), the plasma concentration of PB ranged from 138 to 243.7 μg/ml. In addition, of six paired plasma samples (before and after TPE) obtained from three patients, no significant differences between the concentrations of PB were detected (P=0.6), suggesting that TPE may not significantly affect the plasma concentration of PB. This study confirmed that PB more than 100 µg/ml was effective for adults with RSE. Moreover, TPE may not have an influence on the plasma concentration of PB.Video abstract: http://links.lww.com/WNR/A489.

Abstract
BACKGROUND The determinants of the outcome in adult convulsive status epilepticus(CSE), also the implication of the value of mean arterial blood pressure (MAP), and random blood sugar at admission on the outcome are not clear. OBJECTIVES The objective of this study is to look for the determinants of unfavorable outcome in CSE. MATERIALS AND METHODS Ambispectively gathered data from 55 patients, treated consecutively with identical protocol during January 2010-December 2016, were analyzed. The demographic and clinical variables were identified and correlated with outcome in each individual. RESULTS There were 65.45% males and 34.55% females. Favorable outcome (conscious and discharged) was seen in 63.6%, unfavorable (death 14.5%, absent cortical functions 10.9%, and inability to wean-off anesthetic agents 10.9%). The parameters associated with unfavorable outcome were female gender (odds ratio [OR]: 1.45), MAP ≤80 mmHg (OR: 2.57), time to first medical attention >5 h (OR: 127.8), and time to control clinical seizures >3.5 h (OR: 7.87). Almost 44.2% of patients with SE severity score >2 had unfavorable outcome (sensitivity 75% and specificity 45.7%). New scoring system, the CSE outcome score (CSEOS, developed by combining the predictors associated with higher odds of poor outcome), predicted the poor outcome with the sensitivity and specificity of 90% and 54.29%, respectively. DISCUSSION AND CONCLUSION Low MAP and delay of >3.5 h in treatment initiation or seizure control are the key determinants of poor outcome in CSE. With the incorporation of CSEOS, we believe that our findings can be helpful in the process of clinical decision-making and prognostication of patients with CSE.

Cost of status epilepticus (SE): Effects of delayed treatment and SE duration. Epilepsy Behav 2018; 89:8-14.

Abstract
BACKGROUND The health expenditure related to status epilepticus (SE) is high because of lengthy hospitalization requirements and possible sequelae. We aimed to study the factors associated with this cost including the different timings of the treatment and SE duration. METHODS We evaluated retrospectively all SE recorded in 2 hospitals. The factors studied included the mean cost of hospitalization, demographics, clinical data, duration of hospitalization, in-hospital/out-of-hospital debut, time from onset to treatment, duration of SE, and destination at discharge. RESULTS Three hundred five patients were evaluated (December/2012-July/2017), 195 with out-of hospital and 110 with in-hospital debut. The cost of SE with out-of-hospital onset was significantly lower (6559€ vs 15,174€; p = 0.0001). In out-of-hospital cases, the factors independently related to expenditure were the level of consciousness (p < 0.001), presence of complications (p = 0.005), a potentially fatal etiology (p = 0.008), and duration of the episode (p = 0.003). Duration was significantly higher in patients discharged to a convalescence center (p = 0.006); this variable was significantly related to the time SE onset-arrival to hospital, and SE onset-administration of the treatment. In the in-hospital cases, cost was related to male sex (p = 0.002), the development of complications (p = 0.003), and the etiology (p = 0.016) but was not directly related to the SE duration or to the time onset-treatment. CONCLUSIONS The duration of SE and the speed with which proper management is applied have a direct impact on the healthcare expenditure resulting from out-of-hospital SE. In contrast, the etiology and development of complications are the main factors responsible for expenditure related to in-hospital SE.

Abstract
BACKGROUND Both refractory convulsive status epilepticus (SE) and super-refractory SE are medical emergencies. However, there are limited data on super-refractory SE in children. Thus, this study focuses on characterizing the demographics, outcomes, and prognostic factors for super-refractory SE in children. METHODS This study was a retrospective analysis of super-refractory SE treated in a tertiary referral center in Taiwan. The functional outcome was evaluated by modified Rankin scale (mRS). Significant functional decline was defined as an mRS difference (before hospital admission and at discharge) of more than 2. The variates and the follow-up mRS values were then analyzed statistically. RESULTS We enrolled 134 patients with 191 episodes of convulsive SE and identified 30 patients with 38 episodes of convulsive super-refractory SE. The incidence of convulsive super-refractory SE in the group with SE was 19.9%, and the age ranged from 2.5 months to 17 years. In-hospital mortality was 13.3%, which was much lower than that of adult cohorts. Newly acquired epilepsy and cognitive deficit occurred in 100% and 88.5%, respectively. Newly acquired epilepsy, as a sequel of super-refractory SE, was observed in all 18 patients (100%) who survived and had no history of epilepsy. Significant functional decline (mRS difference of more than 2) at discharge occurred in 76.7%. Poor functional outcome was associated with acute symptomatic etiology (P < 0.001) and the number of anesthetic agents (P = 0.002). The functional outcome improved after 1 year of follow-up in our population. CONCLUSIONS Super-refractory SE is associated with significant morbidity and mortality in children. However, the in-hospital mortality rate is much lower compared with adults. The functional outcome in children is associated with acute symptomatic etiology and the number of anesthetic agents and may improve after long-term follow-up.

Abstract
Refractory and super-refractory status epilepticus (SE) are serious illnesses with a high risk of morbidity and even fatality. In the setting of refractory generalized convulsive SE (GCSE), there is ample justification to use continuous infusions of highly sedating medications-usually midazolam, pentobarbital, or propofol. Each of these medications has advantages and disadvantages, and the particulars of their use remain controversial. Continuous EEG monitoring is crucial in guiding the management of these critically ill patients: in diagnosis, in detecting relapse, and in adjusting medications. Forms of SE other than GCSE (and its continuation in a "subtle" or nonconvulsive form) should usually be treated far less aggressively, often with nonsedating anti-seizure drugs (ASDs). Management of "non-classic" NCSE in ICUs is very complicated and controversial, and some cases may require aggressive treatment. One of the largest problems in refractory SE (RSE) treatment is withdrawing coma-inducing drugs, as the prolonged ICU courses they prompt often lead to additional complications. In drug withdrawal after control of convulsive SE, nonsedating ASDs can assist; medical management is crucial; and some brief seizures may have to be tolerated. For the most refractory of cases, immunotherapy, ketamine, ketogenic diet, and focal surgery are among several newer or less standard treatments that can be considered. The morbidity and mortality of RSE is substantial, but many patients survive and even return to normal function, so RSE should be treated promptly and as aggressively as the individual patient and type of SE indicate.

Abstract
OBJECTIVE This study investigated whether there is an association between semiology of status epilepticus (SE) and response to treatment and outcome. METHOD Two hundred ninety-eight consecutive adult patients (160 females, 138 males) with SE at the University of Munich Hospital were prospectively enrolled. Mean age was 63.2±17.5 (18-97) years. Patient demographics, SE semiology and electroencephalography (EEG) findings, etiology, duration of SE, treatment, and outcome measures were investigated. Status epilepticus semiology was classified according to a semiological status classification. Patient's short-term outcome was determined by Glasgow Outcome Scale (GOS). RESULTS The most frequent SE type was nonconvulsive SE (NCSE) (39.2%), mostly associated with cerebrovascular etiology (46.6%). A potentially fatal etiology was found in 34.8% of the patients. More than half (60.7%) of the patients had poor short-term outcome (GOS≤3) with an overall mortality of 12.4%. SE was refractory to treatment in 21.5% of the patients. Older age, potentially fatal etiology, systemic infections, NCSE in coma, refractory SE, treatment with anesthetics, long SE duration (>24h), low Glasgow Coma Scale (GCS) (≤8) at onset, and high Status Epilepticus Severity Score (STESS-3) (≥3) were associated with poor short-term outcome and death (p<0.05). Potentially fatal etiology and low GCS were the strongest predictors of poor outcome (Exp [b]: 4.74 and 4.10 respectively, p<0.05). CONCLUSION Status epilepticus semiology has no independent association with outcome, but potentially fatal etiology and low GCS were strong predictive factors for poor short-term outcome of SE.

Abstract
PURPOSE OF REVIEW Status epilepticus (SE) is a multisystem disorder. Initially, complications of a massive catecholamine release followed by the side effects of medical therapies, impact patients' outcomes. The aim of this article is to provide an updated summary of the systemic complications following SE. RECENT FINDINGS In recent years, the importance of the multifaceted nature of SE and its relationship with clinical outcomes has been increasingly recognized. The cumulative systemic effects of prolonged seizures and their treatment contribute to morbidity and mortality in this condition. Most systemic complications after SE are predictable. Anticipating their occurrence and respecting a number of simple guidelines may improve the prognosis of these patients.

Abstract
OBJECTIVE The objective of this study was to determine the predictors of outcomes and refractoriness in status epilepticus (SE). METHODS This is a prospective study of 59 adult patients with SE who were admitted to the Emergency Department between February 2012 and December 2013. The effects of clinical, demographic, and electrophysiologic features of patients with SE were evaluated. To evaluate outcome in SE, STESS, mSTESS, and EMSE scales were used. RESULTS Logistic regression analysis showed that being aged ≥65years (p=0.02, OR: 17.68, 95% CI: [1.6-198.4]) for the short term and having potentially fatal etiology (p=0.027, OR: 11.7, 95% CI: [1.3-103]) for the long term were the only independent predictors of poor outcomes; whereas, the presence of periodic epileptiform discharges (PEDs) in EEG was the only independent predictor of refractoriness (p=0.032, OR: 13.7, 95% CI: [1.3-148.5]). The patients with ≥3 Status Epilepticus Severity Score (STESS) did not have poorer outcomes in the short- (p=0.157) and long term (p=0.065). There was no difference between patients with 0-2, 3-4, and ≥4 mSTESS in the short- and long term in terms of outcome (p=0.28 and 0.063, respectively). Also, there was no difference between subgroups (convulsive SE [CSE], nonconvulsive SE [NCSE], and epilepsia partialis continua [EPC]) in terms of STESS and mSTESS. When patients with EPC were excluded, both STESS and mSTESS scores of the patients correlated with poorer long-term outcomes (p=0.025 and 0.017, respectively). The patients with ≥64 points in the Epidemiology-based Mortality in SE-Etiology, age, comorbidity, EEG (EMSE-EACE) score and those with ≥27 points in EMSE-Etiology, age, comorbidity (EMSE-EAC) score did not have poorer outcomes in the short term (p=0.06 and 0.274, respectively) while they had significantly poorer outcome in the long term (p<0.001 and 0.002, respectively). In subgroup analysis, patients with CSE with ≥64 points in EMSE-EACE had significantly poorer outcome in the both short- and long term (p=0.014 and 0.012, respectively), and patients with CSE with ≥27 points in EMSE-EAC had significantly poorer outcome in the long term (p=0.03) but not in the short term (p=0.186). Outcomes did not correlate with EMSE scores in patients with NCSE and EPC. Status epilepticus was terminated with intravenous (IV) levetiracetam (LEV) in 68.75% of patients and with IV phenytoin (PHT) in 83.3% of patients. No statistically significant difference was found between the two groups in terms of efficacy (p=0.334). CONCLUSION Being aged ≥65years predicts poor short-term outcomes, and having potentially fatal etiology predicts poor long-term outcomes, which highlight the importance of SE treatment management in the elderly. Both STESS and mSTESS are not predictive for poor outcomes in EPC. Excluding patients with EPC, STESS, and mSTESS could predict poor long-term outcomes but not in the short term in SE. Epidemiology-based Mortality in Status Epilepticus score could predict poor outcome in the long term better than STESS and mSTESS. Specifically, EMSE scores correlated with poor outcome in patients with CSE but not with NCSE and EPC. New scales are needed to predict outcome especially in patients with NCSE and EPC. The presence of PEDs in EEG is a predictor of RSE, and EMSE score can also be used to predict RSE. There was no difference in the efficacy of IV LEV and IV PHT in SE. This study is significant for having one of the longest follow-up periods in the literature.

Abstract
PURPOSE Super-refractory status epilepticus (SRSE) represents a challenging medical condition with high morbidity and mortality. In this study, we aimed to establish variables related to SRSE development and outcome. METHODS We retrospectively screened our databases for refractory SE (RSE) and SRSE episodes between January 2001 and January 2015. Baseline demographics, SE characteristics, and variables reflecting the clinical course were compared in order to identify factors independently associated with SRSE occurrence. Within the SRSE cohort, predictors of in-hospital mortality as well as good functional outcome in survivors to discharge were established through univariate and multivariable analyses. RESULTS A total of 131 episodes were included, among those 46 (35.1%) meeting the criteria of SRSE. Comparison of RSE and SRSE episodes revealed a lower premorbid mRS score (odds ratio (OR) per mRS point, 0.769; p=0.039) and non-convulsive SE (NCSE) in coma (OR, 4.216; p=0.008) as independent predictors of SRSE. SRSE in-hospital mortality was associated with age (OR, 1.091 per increasing year; p=0.020) and worse premorbid functional status (OR, 1.938 per mRS point; p=0.044). Good functional outcome in survivors was independently related to shorter SRSE duration (OR, 0.714 per day; p=0.038). CONCLUSION Better premorbid functional status and NCSE in coma as worst seizure type indicate a role of acute underlying etiologies in the development of SRSE. In-hospital mortality in SRSE is determined by nonmodifiable factors, while functional outcome in survivors depends on seizure duration underscoring the need of achieving rapid seizure termination.

Abstract
OBJECTIVE EEG monitoring is increasingly used in critically ill patients, but impact on clinical outcome remains unclear. We aimed to investigate the benefit of repeated extended EEG in the prognosis of patients with non-convulsive status epilepticus (SE). MATERIALS & METHODS We retrospectively collected 29 consecutive patients with non-convulsive SE without coma, who underwent repeated extended EEG between 2013 and 2015. We compared these patients with an historical age-matched group of 58 patients managed between 2011 and 2013 with routine EEG only. We excluded patients treated with therapeutic coma for SE treatment. Outcome at hospital discharge was categorized as return to baseline conditions, new disability, and death. RESULTS Severity of SE was similar in the two groups, with similar proportion of potential fatal etiologies (58% in the extended EEG group vs 60%, P=.529), similar STESS scores (median was three in both groups, P=.714), and comparable acute hospitalization duration (median of 15 vs 11 days, P=.131). The extended EEG group received slightly more anti-epileptic drugs (median was three in both groups, P=.026). Distribution of the outcome categories at hospital discharge was similar (P=.129). CONCLUSIONS Extended EEG used for the management of non-convulsive status epilepticus does not seem to improve clinical outcome, but is associated with a higher number of prescribed anti-epileptic drugs. The benefit of continuous EEG monitoring in non-convulsive SE without coma SE should be addressed through a randomized trial.

Abstract
Objective:To determine the implications of first responses of emergency medical services (EMS) to out-of-hospital status epilepticus (SE) on outcome.Methods:From 2005 to 2014, prehospital and in-hospital data were assessed in consecutive adults admitted to an academic medical center with out-of-hospital SE. Logistic regression was performed to identify variables with a robust association between missed epileptic events by the EMS and no recovery to functional baseline in survivors.Results:Among 213 SE patients, 150 were admitted via EMS. While nonconvulsive SE (NCSE) was missed by the EMS in 63.7%, convulsive SE (CSE) was not missed except in 4 patients with transformation into subtle SE. Missed NCSE was more likely with older age (odds ratio [OR]per year 1.06, 95% confidence interval [CI] 1.02–1.10, p = 0.003) and no seizure history (OR 6.64, 95% CI 2.43–18.1, p < 0.001). The area under the receiver operating characteristic curve for prediction of missed NCSE by these variables was 0.839. Independent predictors for not receiving benzodiazepines were increasing age (ORper year 1.05, 95% CI 1.01–1.08, p = 0.008) and higher Glasgow Coma Scale score (ORper increasing unit 1.21, 95% CI 1.09–1.36, p = 0.001). Missed NCSE was independently associated with increased odds for no return to functional baseline in survivors (OR 3.83, 95% CI 1.22–11.98, p = 0.021).Conclusions:Among patients admitted with out-of-hospital SE, CSE is mostly recognized while NCSE is frequently missed especially in patients with increasing age and no seizure history. This calls for heightened awareness for out-of-hospital NCSE in such patients, as missed NCSE is associated with lack of treatment and less recovery to functional baseline in survivors independent of established outcome predictors.

Abstract
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is potentially lethal, but it is also a treatable autoimmune disorder characterized by prominent psychiatric and neurologic symptoms. It is often accompanied with teratoma or other neoplasm, especially in female patients. Anti-NMDAR antibodies in cerebrospinal fluid (CSF) and serum are characteristic features of the disease, thereby suggesting a pathogenic role in the disease. Here, we summarize recent studies that have clearly documented that both clinical manifestations and the antibodies may contribute to early diagnosis and multidisciplinary care. The clinical course of the disorder is reversible and the relapse could occur in some patients. Anti-NMDAR encephalitis coexisting with demyelinating disorders makes the diagnosis more complex; thus, clinicians should be aware of the overlapping diseases.

Predictors of hospital and one-year mortality in intensive care patients with refractory status epilepticus: a population-based study. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2017; 21:71.

Abstract
Background The aim was to determine predictors of hospital and 1-year mortality in patients with intensive care unit (ICU)-treated refractory status epilepticus (RSE) in a population-based study. Methods This was a retrospective study of the Finnish Intensive Care Consortium (FICC) database of adult patients (16 years of age or older) with ICU-treated RSE in Finland during a 3-year period (2010–2012). The database consists of admissions to all 20 Finnish hospitals treating RSE in the ICU. All five university hospitals and 11 out of 15 central hospitals participated in the present study. The total adult referral population in the study hospitals was 3.92 million, representing 91% of the adult population of Finland. Patients whose condition had a post-anoxic aetiological basis were excluded. Results We identified 395 patients with ICU-treated RSE, corresponding to an annual incidence of 3.4/100,000 (95% confidence interval (CI) 3.04–3.71). Hospital mortality was 7.4% (95% CI 0–16.9%), and 1-year mortality was 25.4% (95% CI 21.2–29.8%). Mortality at hospital discharge was associated with severity of organ dysfunction. Mortality at 1 year was associated with older age (adjusted odds ratio (aOR) 1.033, 95% CI 1.104–1.051, p = 0.001), sequential organ failure assessment (SOFA) score (aOR 1.156, CI 1.051–1.271, p = 0.003), super-refractory status epilepticus (SRSE) (aOR 2.215, 95% CI 1.20–3.84, p = 0.010) and dependence in activities of daily living (ADL) (aOR 2.553, 95% CI 1.537–4.243, p < 0.0001). Conclusions Despite low hospital mortality, 25% of ICU-treated RSE patients die within a year. Super-refractoriness, dependence in ADL functions, severity of organ dysfunction at ICU admission and older age predict long-term mortality. Trial registration Retrospective registry study; no interventions on human participants.

Abstract
Status epilepticus is a neurologic and medical emergency manifested by prolonged seizure activity or multiple seizures without return to baseline. It is associated with substantial medical cost, morbidity, and mortality. There is a spectrum of severity dependent on the type of seizure, underlying pathology, comorbidities, and appropriate and timely medical management. This chapter discusses the evolving definitions of status epilepticus and multiple patient and clinical factors which influence outcome. The pathophysiology of status epilepticus is reviewed to provide a better understanding of the mechanisms which contribute to status epilepticus, as well as the potential long-term effects. The clinical presentations of different types of status epilepticus in adults are discussed, with emphasis on the hospital course and management of the most dangerous type, generalized convulsive status epilepticus. Strategies for the evaluation and management of status epilepticus are provided based on available evidence from clinical trials and recommendations from the Neurocritical Care Society and the European Federation of Neurological Societies.

Abstract
When status epilepticus (SE) remains refractory to appropriate therapy, it is associated with high mortality and with substantial morbidity in survivors. Many outcome predictors such as age, seizure type, level of consciousness before treatment, and mostly, etiology, are well-established. A longer duration of SE is often associated with worse outcome, but duration may lose its prognostic value after several hours. Several terms and definitions have been used to describe prolonged, refractory SE, including "malignant SE," "prolonged" SE, and more recently, "super refractory" SE, defined as "SE that has continued or recurred despite 24 hours of general anesthesia (or coma-inducing anticonvulsants)." There are few data available regarding the outcome of prolonged refractory SE, and even fewer for SE remaining refractory to anesthetic drugs. This article reviews reports of outcome after prolonged, refractory, and "super refractory" SE. Most information detailing the clinical outcome of patients surviving these severe illnesses, in which seizures can persist for days or weeks (and especially those concerning "super-refractory" SE) come from case reports and retrospective cohort studies. In many series, prolonged, refractory SE has a mortality of 30% to 50%, and several studies indicate that most survivors have a substantial decline in functional status. Nevertheless, several reports demonstrate that good functional outcome is possible even after several days of SE and coma induction. Treatment of refractory SE should not be withdrawn from younger patients without structural brain damage at presentation solely because of the duration of SE.

Abstract
OBJECTIVE Our aim was to analyze and compare the use of therapeutic coma (TC) for refractory status epilepticus (SE) across different centers and its effect on outcome. METHODS Clinical data for all consecutive adults (>16 years) with SE of all etiologies (except postanoxic) admitted to 4 tertiary care centers belonging to Harvard Affiliated Hospitals (HAH) and the Centre Hospitalier Universitaire Vaudois (CHUV) were prospectively collected and analyzed for TC details, mortality, and duration of hospitalization. RESULTS Two hundred thirty-six SE episodes in the CHUV and 126 in the HAH were identified. Both groups were homogeneous in demographics, comorbidities, SE characteristics, and Status Epilepticus Severity Score (STESS); TC was used in 25.4% of cases in HAH vs 9.75% in CHUV. After adjustment, TC use was associated with younger age, lower Charlson Comorbidity Index, increasing SE severity, refractory SE, and center (odds ratio 11.3 for HAH vs CHUV, 95% confidence interval 2.47-51.7). Mortality was associated with increasing Charlson Comorbidity Index and STESS, etiology, and refractory SE. Length of stay correlated with STESS, etiology, refractory SE, and use of TC (incidence rate ratio 1.6, 95% confidence interval 1.22-2.11). CONCLUSIONS Use of TC for SE treatment seems markedly different between centers from the United States and Europe, and did not affect mortality considering the whole cohort. However, TC may increase length of hospital stay and related costs. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that for patients with SE, TC does not significantly affect mortality. The study lacked the precision to exclude an important effect of TC on mortality.

Abstract
Anti-N-methyl-d-aspartate-type glutamate receptor autoimmune encephalitis can arise in the setting of ovarian teratoma and often responds to resection. When it occurs in the absence of tumor, failure to respond to treatment may be more likely, and affected patients often require intensive care. To further understand the mechanisms and potential management, we present findings from an autopsy conducted on a young woman who died of refractory autoimmune encephalitis of this type. Rituximab was administered 70 days before death, and both 37 and 14 days before death, CD19+ lymphocytes were only 0.1% of blood cells. Ten sessions of plasmapheresis were performed after rituximab treatment. Nonetheless, the autoantibodies were present in serum 4 days before death, demonstrating ongoing antibody production. The hippocampus and medial temporal lobe demonstrated inflammation with T cell and prominent microglial involvement, but no plasma cells or plasmablasts were found there, or anywhere in the brain, despite an extensive search. Examination of lymph node tissue identified many plasma cells along sinusoids. These findings demonstrate that the antibody-producing cells are long-lived and can reside in lymphoid tissue. Awareness of continuing antibody production, the extra-central nervous system site, the indication for cytotoxic therapy, and the potential for biopsy assessment may lead to more effective treatment.

[PMID: 27213459 PMCID: PMC4882483 DOI: 10.3390/jcm5050054] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Revised: 05/08/2016] [Accepted: 05/16/2016] [Indexed: 11/16/2022] Open
Abstract
Status epilepticus that cannot be controlled with first- and second-line agents is called refractory status epilepticus (RSE), a condition that is associated with significant morbidity and mortality. Most experts agree that treatment of RSE necessitates the use of continuous infusion intravenous anesthetic drugs such as midazolam, propofol, pentobarbital, thiopental, and ketamine, each of which has its own unique characteristics. This review compares the various anesthetic agents while providing an approach to their use in adult patients, along with possible associated complications.

[PMID: 27187485 PMCID: PMC4882482 DOI: 10.3390/jcm5050053] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Revised: 05/05/2016] [Accepted: 05/09/2016] [Indexed: 11/16/2022] Open
Abstract
The aim of this systematic review was to describe particularities in epidemiology, outcome, and management modalities in the older adult population with status epilepticus. There is a higher incidence of status epilepticus in the older adult population, and it commonly has a nonconvulsive presentation. Diagnosis in this population may be difficult and requires an unrestricted use of EEG. Short and long term associated-mortality are high, and age over 60 years is an independent factor associated with poor outcome. Stroke (acute or remote symptomatic), miscellaneous metabolic causes, dementia, infections hypoxemia, and brain injury are among the main causes of status epilepticus occurrence in this age category. The use of anticonvulsive agents can be problematic as well. Thus, it is important to take into account the specific aspects related to the pharmacokinetic and pharmacodynamic changes in older critically-ill adults. Beyond these precautions, the management may be identical to that of the younger adult, including prompt initiation of symptomatic and anticonvulsant therapies, and a broad and thorough etiological investigation. Such management strategies may improve the vital and functional prognosis of these patients, while maintaining a high overall quality of care.
