Intensive immunosuppression with cyclophosphamide in multiple sclerosis. Follow up of 110 patients for 2-6 years.

140 MS patients were treated with intensive I.V. cyclophosphamide immunotherapy and 110 were followed over 2-4 years. Annual relapse rate incidence was calculated over a period of 2 years before and after treatment and repeated neurological scores were made during this period. The conclusions are that 62% of the patients were stabilized during 2-4 years and that clinical improvement of the neurological signs was observed in most of the cases. It is concluded that intensive immunosuppression is able to interfere with the pathological processes involved in the pathogenesis of disseminated sclerosis.
