[Soluble receptors of TNF-alpha in rheumatoid arthritis]. / Rastvorimye retseptory faktora nekroza opukholi pri revmatoidnom artrite.

ABSTRACT

The serum level of soluble TNF-alpha receptors with molecular mass 55 kDa (sTNF-a55R) was measured by enzyme immunoassay with commercial kits in 30 patients with rheumatoid arthritis (RA) and 38 healthy donors. High sTNF-a55R serum levels were registered in 90% of RA patients. These levels correlated with RA activity by DAS. Thus, assay for sTNF-a55R can be used for assessing RA activity.
