Active clinical trials for "Status Epilepticus"

Status epilepticus (SE) is found in 20-30% of patients in coma after cardiac arrest, is often refractory to medical therapy and is considered a negative prognostic factor. Intensity and duration of treatment of refractory and super-refractory post-anoxic SE pose the ethical dilemma between futility of treatments and, conversely, their premature suspension. A recent study by the Epilepsy Center of the San Gerardo Hospital has shown that patients with super-refractory post-anoxic SE and favorable prognostic indicators can achieve a good functional outcome in more than 40% of cases, if treated with intensive and protracted therapy. However, there is profound uncertainty about the best combination of antiseizure medications and anesthetics to use in this condition. A combined anti-glutamatergic therapy with ketamine (anti-NMDA receptor) and perampanel (anti-AMPA receptor), aimed at counteracting the excitotoxicity linked to global cerebral ischemia, could be particularly effective in the treatment of super-refractory SE with post-anoxic etiology. Preliminary results in the first 26 patients treated in the Coordinating Center of the project indicate that this therapy appears safe and highly effective (80% SE resolution, 40% good neurological outcome). The aim of the SUPER-CAT study is to investigate the efficacy and safety of combined therapy with ketamine and perampanel (dual anti-glutamatergic therapy) in patients with post-anoxic super-refractory status epilepticus, compared to other therapies, using a multi-centre, retrospective, cohort study design.

COLETTE is an interventional study for which blood, cerebrospinal fluid and post-mortem tissues are collected in patients with status epilepticus or epilepsy associated to dysimmune encephalitis as well as in control patients, to better understand the pathophysiology of these severe epileptic disorders.

The aim of this observational single-center cohort study is to gain a deeper understanding regarding the effects of treatment adaption based on information from outcome prediction models, risk stratification, as well as treatment monitoring, detection, prevention, and management of complications on course and outcome of adult patients with status epilepticus (SE).

This proposal outlines the steps required for the creation of a pilot database of EEG recordings and de-identified medical records from patients internally referred within the UNMH Comprehensive Epilepsy Center. The UNMH EEG Corpus would be the first database of its kind. Other public databases contain either patient EEG signals or medical records, but without both kinds of information, it is impossible to relate pre-treatment neurobiomarkers with post-treatment prognosis. The database will also contain information that can improve seizure localization based off of scalp and intracranial EEG, and the requisite data for the creation of algorithms that forecast seizure activity; a development that could ultimately lead to novel responsive neural stimulation procedures that suppress seizures before they begin.

This study is to investigate the effects of different treatment characteristics regarding the use of intravenous anesthetic drugs (IVADs) as a rescue treatment for refractory Status epilepticus (RSE) on course and outcome. A retrospective data extraction from the digital medical records, the electroencephalographic and microbiologic database of all consecutive adult patients with Status epilepticus (SE) admitted to the University Hospital Basel is undertaken.

Convulsive and Non Convulsive Status Epilepticus (SE) and Pseudo Status Epilepticus prospective registry. Data collection using a standardized form : demographic data and data related to the SE, including circumstances of onset, dates and times of onset and of seizure control, on-scene clinical findings, clinical features of the seizures, pre-hospital and hospital care providers, timing of antiepileptic and supportive treatments, results of etiological investigations, cause of SE, type and dosage of antiepileptic drugs. Dates and times of EEG monitoring, EEG results. Outcomes including vital status and Glasgow Outcome Scale score at ICU and hospital discharge, day-90 and 1-year after SE and determined based on data in the ICU and/or neurologist charts and/or patients phone interview.

The researchers investigate the use of a simplified electroencephalogram (point-of-care EEG) in the pediatric emergency department for children with impaired consciousness or an ongoing epileptic seizure ("status epilepticus"). In addition, the researchers will compare the simplified EEG with the conventional EEG in the epilepsy outpatient clinic.

A study in the use of the Narcotrend depth of anaesthesia monitor to record a) seizures, and b) monitor a level of sedation referred to as 'burst suppression', in sedated patients in the adult and paediatric intensive care. Studies have shown that patients in coma on the intensive care unit may have subclinical in addition to clinical seizures. Subclinical seizures are seizures that do not show any outward signs and may go undetected. The current gold standard of recording seizures in the intensive care unit is by non-invasive, continuous monitoring of the electrical activity of the brain by electroencephalography (cEEG) using cerebral function analysing monitor (CFAM). This is recorded with simultaneous video recording and is performed by Clinical Neurophysiology departments. There has been a steady increase in demand for this service over recent years. Additionally, CFAM / cEEG is labour intensive and expensive. If trends continue, the proportion of hospitals offering CFAM / cEEG will continue to rise, creating increased demand for specialist staff, of which there are a finite number. Depth of anaesthesia monitors are used by anaesthetists to assess the level of anaesthesia in sedated patients using specialised, automated EEG analysis and are now recommended by NICE (DG6) to tailor anaesthetic dose to individual patients. This study aims to investigate the utility of the Narcotrend depth of anaesthesia monitor to monitor for seizures and burst suppression on the adult and paediatric intensive care unit. These monitors are cheaper and more widely available with the scope to be used at every bed space requiring neuro observation on the intensive care unit. The study aims to recruit all patients who are referred for CFAM / cEEG monitoring at Nottingham University Hospitals (NUH) Trust over a 12 month period. These patients will undergo simultaneous recording using CFAM / cEEG and depth of anaesthesia monitoring.

Prospective longitudinal observational registry study of all patients with epilepsy treated in the Mainz Comprehensive Epilepsy and Sleep Medicine Center with the focus on the course of the disease and quality of life.

The justification of this prospective and multicenter study is based on the absence of published data concerning, status epilepticus (SE), a pathology which seems frequent in the French West Indies (FWI) and French Guiana, and whose etiological and prognostic characteristics are often mentioned or assumed but which remain to be demonstrated. The scientific interest lies both in the knowledge of the epidemiology of this pathology and in the identification of the main etiologies, in particular the underlying brain lesions. The morbidity of SE is significant, associating neurological disorders with impaired consciousness, respiratory, hemodynamic and cardiac rhythm disorders, as well as metabolic disorders such as acidosis. SE-related mortality in the acute phase ranges from 3-40% across studies and regions, while long-term mortality ranges from 17-80% depending on age, cause of SE, comorbidities and the occurrence of complications. The prognosis of this pathology has however improved in recent years in developed countries or countries with a high level of health system. On the other hand, the morbidity and mortality of SE in the French overseas departments is not known, even if these territories are supposed to be at an equivalent level in terms of health system to that of mainland France.
