ABSTRACT

UNLABELLED To evaluate clinical implications of the serum level of soluable receptors of tumor necrosis factor alpha (TNFa) with molecular mass 55 kDa (rTNF-55R) in rheumatoid arthritis, serum levels of rTNF-55R and rTNF-75R were measured with the use of radioimmunoassay in 76 RA patients, 38 donors and in 25 RA patients, 10 donors, respectively. RESULTS: Elevated serum level of rTNF-55R was recorded in 55.3% RA patients. This level correlated with basic clinical and laboratory parameters of RA, the disease activity, values of DAS indices. It is concluded that a serum level of rTNF-55R adequately reflects clinico-laboratory activity of RA and its measurement can be used for assessment of RA activity and treatment efficiency.
