[Immunogenetic prognosis of the effectiveness of cytostatic therapy of rheumatoid arthritis].
The time course of in vitro cellular immune reactions by using cyclophosphane, prospidin , and methotrexate was examined in 39 patients with rheumatoid arthritis to make predictions of the efficacy of its cytostatic therapy. The agents were evaluated for effects on the expression of Ia-like antigens on the peripheral lymphocytes and synovial fluid of the patients. The optimal doses of the agents for this testing had been chosen in the lymphoid cells from MRL31 lpr mice. The active dosage forms of the cytostatics for the experiment were obtained by administering native agents into the retrobulbar plexus of Balb/c mice, followed by blood isolation of active metabolites . The Ia-like antigen pre-expression index which is the ratio of the proportion of Ia-positive lymphocytes in control cultures to that of the cells in the culture after drug addition was used as a marker of the baseline cellular immunity in the patients. The patients having the index more than 1.5 were considered to be sensitive, those with less than 1.5 were insensitive to the drug. Thus, the Ia-like antigen pre-expression index may be used as a predictor in the assessment of the expediency of prospidine use.
