Intraventricular interferon and oral inosiplex in the treatment of subacute sclerosing panencephalitis

Abstract

We treated 22 patients with subacute sclerosing panencephalitis (SSPE) with intraventricular α-interferon (IFN) and inosiplex PO and followed them for 2 to 54 months. Three deaths occurred. Clinical improvement, demonstrated by decreasing scores on the Neurological Disability Index, occurred in 11/22 (50%); five patients became stable, and the progression rate of the disease decreased in three. The remission rate was significantly higher than untreated controls from the same institution. Patients who had a slowly progressive disease responded best to treatment. Serious side effects were rare. We recommend intraventricular IFN, combined with oral inosiplex, in the treatment of SSPE.
