Investigation of efficacy of antibodies ot interferons in rheumatoid arthritis (RA) versus relevant efficacy of the tumor necrosis factor (TNF), comparison of the above cytokines in monotherapy and combined treatment.
An open controlled randomized trial of clinical benefit and tolerance of anticytokine antibodies was performed in a group of RA patients at stage II, III and IV (1, 20 and 4 patients, respectively). The activity degree II and III was in 10 and 15 patients, respectively. All the patients had articular functional insufficiency of the second degree. 21 patients failed previous therapy with basic drugs including immunodepressants.
The anticytokine antibodies proved to be highly effective in RA. Positive changes in teh disease activity were achieved early after the end of the 5-day course in 88% of patients. The most definite immediate therapeutic effect was noted in usage of TNF antibodies both in monotherapy and in combination with other anticytokines. Long-term effect was the best in patients given antibodies to interferon gamma. Interferon-alpha antibodies produced weaker effect. The combined treatment had no advantages over the monotherapy.
A significant therapeutic effect of antibodies to interferon-gamma is indicative of an important role of this cytokine in RA pathogenesis. Anticytokine antibodies are promising as a component of combined therapy of patients with resistant RA.
