Fenfluramine treatment for Dravet syndrome: Long term real-world analysis demonstrates safety and reduced health care burden.

Objective: Fenfluramine (FFA), stiripentol (STP), and cannabidiol (CBD) are approved add-on therapies for seizures in Dravet syndrome (DS). We report on the long-term safety and health care resource utilization (HCRU) of patients with DS treated with FFA under an expanded access program (EAP).

Methods: A cohort of 124 patients received FFA for a median of 2.

Efficacy and Safety of Long-Term Treatment with Stiripentol in Children and Adults with Drug-Resistant Epilepsies: A Retrospective Cohort Study of 196 Patients.

Background: Stiripentol is an antiseizure medication with multiple potential mechanisms of action, indicated as adjunctive therapy in people with Dravet syndrome, whose seizures are not adequately controlled with clobazam and valproate. However, there are scattered data on its efficacy in other epilepsy aetiologies and types. We previously reported our single-centre experience on the efficacy of adjunctive stiripentol treatment in a cohort of 132 patients with different types of refractory epilepsies.

Phenotypic and genetic spectrum of ATP6V1A encephalopathy: a disorder of lysosomal homeostasis.

Vacuolar-type H+-ATPase (V-ATPase) is a multimeric complex present in a variety of cellular membranes that acts as an ATP-dependent proton pump and plays a key role in pH homeostasis and intracellular signalling pathways. In humans, 22 autosomal genes encode for a redundant set of subunits allowing the composition of diverse V-ATPase complexes with specific properties and expression. Sixteen subunits have been linked to human disease.

Orphan Drug Use in Patients With Rare Diseases: A Population-Based Cohort Study.

Orphan drugs are used for the diagnosis, prevention and treatment of rare diseases that, in the European Union, are defined as disorders affecting no more than 5 persons in 10,000. So far, a total of around 800 orphan medicinal products have been approved by the European Medicines Agency, however the utilization profile of orphan drugs has yet to be explored. This study aimed at assessing the utilization profile of orphan drugs authorized for marketing by the Italian Medicines Agency using population-based data.

Long-term efficacy of add-on stiripentol treatment in children, adolescents, and young adults with refractory epilepsies: A single center prospective observational study.

Objective: To assess the long-term efficacy and tolerability of stiripentol (STP) as an adjunctive treatment in different forms of refractory epilepsies.

Methods: The medical records of all individuals consecutively treated with STP as add-on therapy for refractory epilepsies, irrespective of their being focal, generalized, or both, and followed at Meyer Children's Hospital between January 2007 and May 2018, were reviewed. The drug scheme administration consisted of a starting dose of STP of 10-15 mg/kg/d with increments every week, up to a maximum of 50 mg/kg/d, based on both age and weight.
