The use of interferon beta in relapsing-remitting multiple sclerosis.

The use of interferon beta-1a to treat multiple sclerosis in a child of 7 years of age is discussed. To date, there is only one other published report of the use of interferon beta in a child as young as this. One year after commencing treatment she had shown significant clinical improvement, with a marked reduction in number of relapses. In her second year of treatment she suffered a major relapse from which she slowly recovered.
