Zusammenfassung

Die Epilepsien des Kindes- und Jugendalters sind die häufigste neurologische Erkrankung ebendieser Altersgruppe und weisen eine Krankheitshäufigkeit von 0,5 – 1 % in Industrieländern auf.

Die ketogene Diät und die modifizierte Atkins-Diät konnten sich in den letzten beiden Jahrzehnten insbesondere bei Patienten mit pharmakoresistenter oder schwer behandelbarer Epilepsie als potente Behandlungsmöglichkeit etablieren. Heute sind die ketogenen Ernährungstherapien aber auch fixer Bestandteil möglicher Therapieoptionen (pharmakologisch und nicht pharmakologisch) bei jungen aber auch älteren Patienten mit verschiedensten Erkrankungen des zentralen Nervensystems (Glukosetransporterdefekte, Pyruvat-Dehydrogenase-Mangel etc.).

Die ketogene Diät und die modifizierte Atkins-Diät sind fettreiche, kohlenhydratarme Ernährungsformen, welche ähnlich dem Fasten eine Ketose induzieren. Die entstehenden Ketonkörper können als alternative Energiequelle verstoffwechselt werden, insbesondere das Gehirn von Kindern erreicht eine bis zu 4 – 5-fach höhere Ketonkörperverwertung im Vergleich zu Erwachsenen und ist daher besonders prädestiniert für diese Behandlungsform. Diese Therapieformen eröffnen uns die Möglichkeit, zusätzlich zur pharmakologischen Behandlung von Anfallsleiden auch über die Modifikation der Ernährung auf die Anfallskontrolle Einfluss nehmen zu können. Die gepoolte Odds Ratio für Responderraten (> 50 %ige Anfallsreduktion) liegt in Abhängigkeit der zugrunde liegenden Literatur bei in etwa 2,25. Die vorliegende Übersichtsarbeit soll einen aktuellen Überblick über Indikationen, Wirkungen, Nebenwirkungen und praktische Anwendbarkeit dieser Therapieform bei verschiedensten Erkrankungen im Kindes- und Jugendalter geben.

Abstract

Pediatric epilepsies are among the most common neurological disorders in this age group with a prevalence of about 0.5 – 1 % in industrialized countries. The Ketogenic Diet and the Modified Atkins Diet are well-known, non-pharmacological therapeutic options for patients with pharmacoresistant epilepsy without the possibility for epilepsy surgery. The Ketogenic Diet and the Modified Atkins Diet are based on high-fat, low carbohydrate and balanced protein intake in childhood mimicking a fasting state subsequently leading to the production of ketone bodies as an alternative source of energy. Due to the fact that ketone utilisation and extraction in children are about fourfold those in adults, the Ketogenic Diet might be particularly favourable in this age group. Therefore, the Ketogenic Diet and the Modified Atkins Diet provide the possibility to improve seizure control beyond pharmacological epilepsy treatment. The pooled Odds Ratio for responder rates (> 50 % seizure reduction) reaches approximatively 2.25. The present overview comprises an up-to-date summary of indications, efficacy, side-effects and practical applicability of this newly discovered therapeutic option for various diseases in childhood.
