Lymphocytapheresis therapy in multiple sclerosis, a preliminary study.

10 patients with definite multiple sclerosis (MS), most of them with the chronic progressive type, were treated with lymphocytapheresis during one year. The DSS (Disability Status Scale) improved in 4 patients during the intensive phase of treatment, remained stable in 5 patients and deteriorated in one. The NSS (Neurological Status Scale) showed a stabilisation for the majority of the neurologic functions. Using the ISS (Incapacity Status Scale), an improvement was measured in 6 patients, a stabilisation in one and a deterioration in 3. Exacerbations could not be prevented by lymphocytapheresis.
