- Abstract
Aim: To assess efficacy and tolerance to anti-B-cell drug rituximab in therapy of rheumatoid arthritis (RA) by the data of RF register of this drug., Material and Methods: Rituximab was studied in 42 patients with high RA activity. 37 patients received rituximab according to a conventional scheme: 2 intravenous 1000 mg infusions with a 2-week interval. The rest patients received 2 intravenous 500 mg infusions. The response was evaluated by DAS28 index., Results: Rituximab administration resulted in almost complete elimination of B-cells from peripheral blood. This produced a significant positive effect manifesting with reduction in the number of inflamed and painful joints. This trend was evident to observation week 8 reaching maximum to week 24. Clinical response correlated with decline of inflammation as shown by ESR and CRP. According to DAS28 index, good and satisfactory results were registered in 8 weeks in 62% patients, in 16 weeks--in 86%, in 24 weeks--in 100%. Rituximab tolerance was good., Conclusion: Effective treatment with rituximab for rheumatoid arthritis opened a new perspective in antirheumatic biological therapy and demonstrated an important role of B-cells in the disease development. This drug is recommended for wide use in the treatment of severe rheumatoid arthritis resistant to prior therapy including TNF-alpha blockers.
