Abstract
English
Epilepsy is a widely prevalent condition and holds significant relevance in Germany as well. Levetiracetam (LEV) is a well-tolerated medication commonly used in pharmacological therapy and has become one of the most frequently prescribed anticonvulsants. However, there is currently insufficient evidence regarding which patient characteristics could predict the effectiveness of LEV. Additionally, there is a lack of sufficient data on which of the numerous drug combinations are most effective for specific patient subgroups. This study investigated the effectiveness of LEV in a cohort of 226 patients, which were randomly selected from the Clinic of Neurology at the Universitätsmedizin Göttingen. The analysis focused on determining whether factors such as gender, age, type of epilepsy, etiology, as well as the specific combinations and dosages, influenced the effectiveness of LEV and the occurrence of adverse effects. The goal was to develop potential predictive models for LEV effectiveness. No significant correlation was found between gender or age and LEV effectiveness. However, LEV was significantly more effective in achieving seizure freedom in patients with generalized epilepsy compared to those with focal epilepsy. Regarding the etiology, the best efficacy was observed in patients with a genetic cause of epilepsy, although this finding was not statistically significant. Among the various drug combinations, the combination of LEV and valproate demonstrated the best efficacy. On the contrary, the combination of LEV with sodium channel blockers was associated with lower probabilities of improved seizure control. No reliable prediction of LEV effectiveness was possible based on the administered daily dose. Regarding side effects, these were generally milder in younger patients, whereas neurotoxic side effects occurred significantly more frequently in patients aged ≥60 compared to younger individuals. A weak but significant correlation was found between the LEV dose and the severity of side effects. In conclusion, the data presented in this study did not allow for the development of reliable predictive models for LEV effectiveness. Further studies are needed to address these gaps and provide clearer insights.
