Therapy of multiple sclerosis in children and adolescents

BackgroundPaediatric multiple sclerosis accounts for up to 10% of all MS cases. The initial course of the disease is relapsing-remitting in most children, with a relapse rate generally higher than that observed in adult patients. There is published experience on the use of first-line disease modifying therapies in children with MS. However, about 1/3 of paediatric MS cases do not respond to IFN-β or glatiramer acetate and continue to develop relapses and disease progression. These patients could be proposed to a second-line treatment.MethodsA comprehensive review of the published literature related to pharmacologic treatment of MS in adults and paediatric patients was performed. The recent literature has been extracted for new evidence from controlled trials in adult patients, and open treatment studies and reported expert opinion in paediatric patients.ResultsNo disease modifying drug has been approved for the treatment of children and adolescents with MS, although the currently available first-line therapies for adults seem to be safe and well tolerated in this population. Further studies are required to assess the safety and efficacy of second-line treatments in children with MS.ConclusionThe present article constitutes an update of the existing publications regarding treatment of acute events of CNS demyelination in children and adolescents as well as considerations for the use of immunomodulatory therapies.
