Infantile Spasm Clinical Trial
Official title:
Efficacy of Vigabatrin With High Dose Prednisolone Combination Therapy Versus Vigabatrin Alone for Infantile Spasm: a Randomized Trial
Infantile spasms (IS) are seizures associated with a severe infantile epileptic encephalopathy. Both cessation of spasms and electrographic response are necessary for the best neurodevelopmental outcomes. Adrenocorticotrophic hormone (ACTH), or prednisolone, or vigabatrin are considered the first-line treatment individually. However, ACTH expense and availability are the barriers in developing countries including Thailand. Vigabatrin, therefore, is the first recommended by Epilepsy Society of Thailand due to ACTH unavailability. Recently, combined steroid treatments (either ACTH or high dose prednisolone) with vigabatrin are superior in cessation of spasms compared to steroid treatment alone. Thus, this study is aimed to compare the efficacy of vigabatrin with high dose prednisolone combination therapy and vigabatrin alone.
Infantile spasms are recognized as epileptic encephalopathy which include the hypsarrhythmia or variants electroencephalographic (EEG) features and psychomotor regression. Various underlying conditions are associated with the infantile spasm included cerebral malformation, hypoxic ischemic encephalopathy, genetic disorders (Down syndrome), tuberous sclerosis complex (TSC), etc. Although vigabatrin has the evidence to use as the first line treatment for infantile spasm related with TSC. Adrenocorticotrophic hormone (ACTH), or high dose prednisolone, or vigabatrin are the first line treatment of IS in non-TSC. The effectiveness of ACTH versus high dose prednisolone question have not yet definitely answered. Furthermore, ACTH expense and availability are the barriers in developing countries including Thailand. Vigabatrin, therefore, is the first option of therapy recommended by Epilepsy Society of Thailand due to ACTH unavailability. Recently, combined steroid treatments (either ACTH or high dose prednisolone) with vigabatrin are superior in cessation of spasms compared to steroid treatment alone. Questions about the clinical cessation of IS and electrographic remission by combination treatment with vigabatrin and high dose prednisolone compare to vigabatrin alone have not fully elucidated. Thus, this study is aimed to compare the efficacy of vigabatrin with high dose prednisolone combination therapy and vigabatrin alone. ;
