BACKGROUND: Infantile epileptic spasm syndrome (IESS) and periventricular leukomalacia (PVL) cause developmental regression and poor neurological outcomes. The primary treatments for IESS include adrenocorticotropin and vigabatrin; however, no study has yet evaluated the efficacy of vigabatrin for patients with both IESS and PVL. Therefore, we investigated the efficacy and safety of vigabatrin in patients with both disorders.
METHODS: We retrospectively enrolled patients with IESS and PVL who were treated with vigabatrin. We performed ophthalmological examinations and electroretinography (ERG) before and after vigabatrin. Treatment response was defined as complete cessation of epileptic spasms and no other seizures after 3 months of vigabatrin. We investigated the responses to vigabatrin, doses used, and adverse effects.
RESULTS: Seven patients (5 males) with IESS and PVL were treated with vigabatrin. The median age at vigabatrin initiation was 10 (range, 7-25) months. Three of the seven patients (42.8%) showed complete clinical cessation of epileptic spasms after 3 months of vigabatrin. The median duration between vigabatrin initiation and epileptic spasm cessation was 5 (range: 3-61) days. The adverse effects included poor feeding (n = 1) and abnormal ERG findings during vigabatrin therapy (n = 2). These ERG findings normalized after vigabatrin was reduced or stopped. No respiratory failure, increased secretion, or somnolence was observed.
CONCLUSION: Vigabatrin was effective for treating 42.8% of our patients with both IESS and PVL. Vigabatrin was well tolerated, with only a mild effect observed in patients with IESS and PVL. Some treatment-related ERG abnormalities were normalized after vigabatrin was reduced or stopped.
