Patients and methods: We studied 368 Russian patients with rheumatoid arthritis. All of them were treated in accordance with the standard recommendations. Fifty seven patient received biological disease-modifying antirheumatic drugs. Single nucleotide polymorphisms (TNFО± C-863A, TNFО± G-308A, TNFО± G-238A, IL1ОІ T-31РЎ, IL4 РЎ-590T, IL6 G-174C, IL10 A-1082G, IL10 РЎ-592Рђ, VEGFA C+936T, VEGFA C-2578A) were determined by restriction fragment length polymorphism analysis of PCR-amplified fragments (PCR-RFLP) or RT-PCR. Results: The IL1ОІ T-31C and VEGFA C+936T SNPs were association with bDMARDs treatment. Homozygotes IL1b -31CC and VEGFРђ +936 CC were more frequently in bDMARDs group compare with patients without bDMARDs (28.1% vs 17.1%, p=0.044 and 80.4% vs 66.6%, p=0.041). Other polymorphisms didn’t demonstrate any significant differences. Conclusions: Our data suggest, that IL1ОІ T-31C and VEGFA C+936T SNPs can be used as part of a comprehensive assessment of the prognosis of the treatment effectiveness.
