NCT ID: NCT06201897 Recruiting - West Syndrome Clinical Trials

Cortical Excitability in West Syndrome Using Transcranial Magnetic Stimulation

Start date: March 2024
Phase: Phase 2/Phase 3
Study type: Interventional

Currently, no literature is available regarding degree of cortical excitability and its correlation with various epileptic syndromes and disorders such as West Syndrome in pediatric age group. Studying the complex interaction of cortical excitability, seizures, neurobehavioral patterns and brain maturation in children may provide valuable information and new insights about the underlying neuropathogenic pathways in childhood epilepsy. West Syndrome is a unique epilepsy syndrome amalgamating infantile onset epilepsy with significant neurodevelopmental delay. Due to this reason, it is the ideal disorder to study this complex interaction. How cortical excitability correlates with disease activity in West Syndrome is speculative. The ability of disease characteristics such as degree of cortical excitability to predict successful outcome after ACTH therapy (non-invasive biomarker of treatment response) in children with West Syndrome has not been explored. Most importantly, the present study may be a hypothesis generating initial step bringing new insights into neurocognitive effects of seizures, seizure pathogenesis, individualized antiepileptic drug therapy and for studying treatment response. The investigators aim to determine the change in cortical excitability pre and post ACTH therapy, in children with West syndrome and whether the change predicts responsiveness to ACTH therapy, in terms of reduction in spasm frequency at 12 weeks.

NCT ID: NCT05279118 Active, not recruiting - Ketogenic Diet Clinical Trials

Ketogenic Diet vs ACTH for the Treatment of Children With West Syndrome

Start date: March 1, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

Children with West syndrome are prone to refractory seizures with poor neurocognitive outcome overall. The current standard of care consists of treatment with ACTH, but the grade of evidence is not high and not much RCTs are available. Ketogenic diet is an effective and well tolerated treatment option in drug refractory epilepsy and also in refractory west syndrome. In view of minimal side effects, better cost parameters and ability to continue for a longer duration our study aiims to investigate the efficacy of ketogenic diet as a first line therapy in comparison to ACTH therapy. Children with west syndrome after satisfying the inclusion and exclusion criteria will be randomised into the two treatment arms and primary response will be noted at the end of 6 weeks of therapy in terms of mean percentage of spasm reduction.

NCT ID: NCT05126914 Not yet recruiting - Epilepsy Clinical Trials

Multicentre Real-life Follow-up Study of Rare Epileptic Syndromes in Children and Adolescents

EPIRARE
Start date: December 2021
Phase:
Study type: Observational

Rare epilepsies as a whole account for 20-30% of epilepsies, but knowledge about prognostic factors is currently limited. This means that it is difficult to provide adequate information to families at diagnosis and during follow-up. Prognostic factors are also important for management as they can have an impact on the patient's outcome (time to intervention, choice of one molecule over another, etc.). Finally, few treatments are currently available for these epilepsies. One of the limitations to the development of treatments is the lack of real life data as it is difficult to create reliable primary endpoints such as the rate of patients becoming seizure free naturally compared to a therapeutic intervention. The aim of this real-life study is to evaluate the response to treatment as well as to see the evolution of cognitive and psychiatric comorbidities. As explained above, there are very few randomised trials except for 3 rare epilepsies (infantile spasm syndrome, Dravet syndrome, Lennox-Gastaut syndrome). This has led to the virtual absence of management recommendations, including for the three syndromes mentioned above, where attempts at treatment algorithms have been proposed, although these have not been able to be considered as evidence-based recommendations. As a result, there is some diversity in the management of rare epilepsies from one centre to another. However, this diversity in management can be an asset in a real-life study. This will make it possible to compare different management methods, both in terms of seizure control and medium-term outcome.

NCT ID: NCT04302116 Recruiting - Infantile Spasm Clinical Trials

Vigabatrin With High Dose Prednisolone Combination Therapy vs Vigabatrin Alone for Infantile Spasm

Start date: May 18, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02885389 Completed - Infantile Spasms Clinical Trials

Molecular Genetics in Infantile Spasms

Start date: October 2010
Phase: N/A
Study type: Observational

Infantile Spasms syndrome (ISs) is a characterized by epileptic spasms occurring in clusters with an onset in the first year of life. West syndrome represents a subset of ISs that associates spasms in clusters, a hypsarrhythmia EEG pattern and a developmental arrest or regression. Aetiology of ISs is widely heterogeneous including many genetic causes. Many patients, however, remain without etiological diagnosis, which is critical for prognostic purpose and genetic counselling. In the present study, the investigators performed genetic screening of 73 patients with different types of ISs by array-CGH and molecular analysis of 5 genes: CDKL5, STXBP1, KCNQ2, and GRIN2A, whose mutations cause different types of epileptic encephalopathies, including ISs, as well as MAGI2, which was suggested to be related to a subset of ISs.

NCT ID: NCT01575639 Completed - Infantile Spasms Clinical Trials

Prednisolone in Infantile Spasms- High Dose Versus Usual Dose

Start date: February 2012
Phase: Phase 3
Study type: Interventional

Infantile spasms comprise a difficult to treat type of epilepsy in young children. Hormonal treatment, i.e. Prednisolone and ACTH are considered the treatment of choice. There is no consensus on the dosage of Prednisolone required for the treatment of infantile spasms. Recent data has shown that a high dose (4 mg/kg/day) may be more efficacious than the usual dose (2 mg/kg/day). However, there are no randomized controlled trials comparing these doses. A higher steroid dose may also be associated with more side effects. Therefore, this study was planned to compare the efficacy and tolerability of the high dose versus the usual dose in children with infantile spasms, in a randomized open-label trial design

NCT ID: NCT01367964 Active, not recruiting - West Syndrome Clinical Trials

Prevention of West Syndrome With Low-dose Adrenocorticotropin Hormone (ACTH)

PREVENT-WS
Start date: July 2011
Phase: N/A
Study type: Interventional

West syndrome (WS) is a specific type of epilepsy (or seizure disorder) that has three features: infantile spasms (type of seizure), loss of milestones, and a specific pattern on electroencephalogram (EEG or brain wave test) called hypsarhythmia. The purpose of this study is to detect pre-hypsarhythmia in infants at high-risk for WS and determine whether treatment with ACTH will prevent WS.
