THE RESULTS OF THE CLINICOIMMUNOLOGICAL TESTING OF MYELOPID IN CHRONIC FORMS OF MULTIPLE-SCLEROSIS

Forty patients with a verified diagnosis of multiple sclerosis . (MS), the majority of whom had the secondary progressive form of the disease, received, a short-term treatment with myelopid (MP). After this 10 patients were given a long-term treatment with MP. The clinical trial was carried out by the double blind method using placebo. The patients' status was estimated by special evaluation scales (clinical), immunoassays (the content of T lymphocyte subpopulations, reaction of blast transformation of leukocytes to mitogens under different conditions of cultivation including that in the presence of 0.3-mu-g/ml MP, by assessment of the production and activity of interleukin-2), by the method of evoked potentials and NMR tomography. 60 % of the patients manifested an improvement of the clinical status after the short-term MP treatment, which was accompanied by positive dynamics of evoked potentials and a decrease of the functional activity of the cells in the reaction of blast transformation of leukocytes. In such patients, MS ran a more favourable course during 0.5-1.5 years of observation. In 8 patients with the immunologic signs of the pathological process activation, the clinical status worsened after MP. The correlation and regression analyses allowed one to specify the clinico-immunologic indications and contraindications for MP administration. The clinico-immunologic changes noted were not recorded after placebo. In the patients receiving the long-term treatment, one could see a further decline of the functional activity of the cells in the reaction of blast transformation of leukocytes, a rise of the content of T suppressors/killers in the blood, a favourable clinical course of MS. Therefore, MP can be used for the treatment of MS patients in the inactive disease stage and under the control of the immunity status.
