title: [Alpha interferon in the treatment of multiple sclerosis. Update and experience in Cuba].
abstract: OBJECTIVE
  We present an update of specific treatment for multiple sclerosis (MS), especially the form with a clinical course of exacerbation-remission (ER), in which we consider the benefits of beta interferons, copolymer 1 and intravenous immunoglobulin. We discuss the properties of alpha interferon and its modes of action which are very similar to those of beta interferon. The main clinical trials in which various subtypes of alpha interferons were used are summarized.
  
  
  METHODS
  We establish the elements which justify interest in studying this substance and present the main trials carried out in Cuba. These consist in an initial trial in 9 patients, with encouraging results in the clinical course ER-MS and following this, the findings of a preliminary study of the first 17 patients of a randomized, double-blind National Clinical Trial, in which a placebo was used for control.
  
  
  CONCLUSIONS
  In view of these results we recommend that the study being carried out in Cuba to confirm the efficacy of alpha interferon in the ER-MS form be continued.
