Hypothermia as an adjuvant treatment in paediatric refractory or super-refractory status epilepticus
No full textInternational audienceTherapeutic hypothermia is among the adjuvant therapies suggested for refractory or super-refractory status epilepticus (R/SR-SE) in paediatric patients. Experimental evidence of neuroprotective and antiseizure effects provides a strong rationale for using therapeutic hypothermia in patients with status epilepticus. Thus, hypothermia between 20°C and 33°C in animals with status epilepticus is associated not only with significantly less neuronal damage, predominantly in the hippocampal CA1, CA2, and CA3 areas, but also with increased seizure latency and decreased seizure frequency and duration. Therapeutic hypothermia has rarely been used in paediatric R/SR-SE. In the few reported cases, seizure control was markedly improved but nearly half the patients experienced recurrences after rewarming. Studies are needed to clarify the modalities and indications of therapeutic hypothermia in paediatric patients with R/SR-SE. What this paper adds: Hypothermia at 20°C to 33°C is neuroprotective and has antiseizure effects in experimental status epilepticus. In children, antiseizure effects are marked but recurrences after rewarming are common

Single versus serial measurements of neuron-specific enolase and prediction of poor neurological outcome in persistently unconscious patients after out-of-hospital cardiac arrest - A TTM-trial substudy
No full textBackground: Prediction of neurological outcome is a crucial part of post cardiac arrest care and prediction in patients remaining unconscious and/or sedated after rewarming from targeted temperature management (TTM) remains difficult. Current guidelines suggest the use of serial measurements of the biomarker neuron-specific enolase (NSE) in combination with other predictors of outcome in patients admitted after out-of-hospital cardiac arrest (OHCA). This study sought to investigate the ability of NSE to predict poor outcome in patients remaining unconscious at day three after OHCA. In addition, this study sought to investigate if serial NSE measurements add incremental prognostic information compared to a single NSE measurement at 48 hours in this population. Methods: This study is a post-hoc sub-study of the TTM trial, randomizing OHCA patients to a course of TTM at either 33°C or 36°C. Patients were included from sites participating in the TTMPLOS trial biobank sub study. NSE was measured at 24, 48 and 72 hours after ROSC and followup was concluded after 180 days. The primary end point was poor neurological function or death defined by a cerebral performance category score (CPC-score) of 3 to 5. Results: A total of 685 (73%) patients participated in the study. At day three after OHCA 63 (9%) patients had died and 473 (69%) patients were not awake. In these patients, a single NSE measurement at 48 hours predicted poor outcome with an area under the receiver operating characteristics curve (AUC) of 0.83. A combination of all three NSE measurements yielded the highest discovered AUC (0.88, p = .0002). Easily applicable combinations of serial NSE measurements did not significantly improve prediction over a single measurement at 48 hours (AUC 0.58-0.84 versus 0.83). Conclusion: NSE is a strong predictor of poor outcome after OHCA in persistently unconscious patients undergoing TTM, and NSE is a promising surrogate marker of outcome in clinical trials. While combinations of serial NSE measurements may provide an increase in overall prognostic information, it is unclear whether actual clinical prognostication with low false-positive rates is improved by application of serial measurements in persistently unconscious patients. The findings of this study should be confirmed in another prospective cohort
Managing Status Epilepticus in the Older Adult
No full textThe 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
Patient-reported outcomes in adults after status epilepticus: A systematic review
No full textInternational audienceImpairments after status epilepticus have generally been assessed by physicians, using generic scales. Patient-reported outcomes (PROs) directly reflect each patient s experience and are therefore recommended to improve patient-centered care. The objective of this systematic review was to compile the available information on patient-reported outcomes of adults after status epilepticus. We used Medical Subject Headings terms to search PubMed, Embase, and the Cochrane Library from database inception to February 2023. We excluded reviews, case reports, abstract-only reports, editorials, and publications in languages other than English or French. Studies reporting PROs in adults after SE were eligible. Bias in included studies was assessed using the Newcastle-Ottawa Scale (NOS). Given the heterogeneity in assessment tools and outcomes, most of the results are presented separately for each included study. Only three studies met our criteria. All used an observational cohort design. Two were retrospective and one prospective. Of the 141 patients (76 males and 65 females, mean age 43u201363 years), 105 (74.4 %) had a history of epilepsy before status epilepticus. The studies used four epilepsy-specific and five generic tools to assess five patient-reported outcomes: quality of life (n = 141), mental health (depression, n = 81, or anxiety, n = 49), physical health including fatigue (n = 130), return to work (n = 49), and side effects of antiepileptic drugs (n = 81). A single study (n = 81) was of good methodological quality. Health-related quality of life (HRQOL) and mental health were the most extensively studied outcomes, and both were impaired. HRQOL scores ranged from 41.7 ± 11.5 to 48.3 ± 24.5. The prevalence of depression and anxiety varied from 30 % to 36 %, and from 22 % to 62 %, respectively. However, data were not collected before the status epilepticus episode, and the possible impact of this last on the outcomes cannot therefore be assessed. Information on PROs of adults after status epilepticus is extremely scant. Patient-reported outcomes should be collected more widely in adults after status epilepticus
