Zusammenfassung
Trotz bislang im deutschsprachigen Raum nicht erfolgter Zulassung wird Valproinsäure (VPA) intravenös zur Therapie des Status epilepticus (SE) inkl. des Status generalisierter tonisch-klonischer Anfälle (SEGTKA) eingesetzt. Evidenzklasse-I/II-Daten von randomisierten und verblindeten Studien liegen nicht vor. Eine Expertenkonferenz unter Beteiligung von Grundlagenforschern sowie Neuropädiatern und Neurologen hat die bislang vorliegenden Erfahrungen aus der Literatur und der beteiligten Autoren mit der intravenösen VPA-Therapie beim SE nach kritischer Diskussion zusammengefasst. Für VPA liegt noch keine ausreichende Evidenz und im deutschsprachigen Raum keine Zulassung vor. Es wird aufgrund von Evidenzklasse-III/IV-Daten im „Off-label”-Einsatz intravenös nach erfolgloser Vorbehandlung (Benzodiazepine, Phenytoin, Phenobarbital) eingesetzt. Es werden Empfehlungen zur Dosierung und zum Monitoring gegeben. Zur Verbesserung der Datenlage wird ein prospektives Register der SEGTKA-Therapie vorgeschlagen.
Abstract
In spite of lacking approval intravenous valproic acid (VPA) is used for therapy of status epilepticus (SE) including status epilepticus of generalized tonic-clonic seizures (SEGTCS). Evidence class I and II data from randomised and blinded studies are not available. An expert panel including basic scientists and neuropediatricians as well as neurologists evaluated and summarized the currently available data from the literature and the clinical experience of the participating authors regarding the use of intravenous VPA in SE. In the german speaking countries intravenous VPA is not yet approved for therapy of SE. It is used „off-label” based on evidence from class III and IV data following unsuccessful pretreatment with benzodiazepines, phenytoin, or phenobarbital. Recommendations regarding dosage and monitoring are given. A prospective registre of the use of intravenous VPA in SEGTCS is suggested to get more reliable data.
