Anti-CCP single test device
The finding that rheumatoid arthritis (RA) patients often produce antibodies against citrullinated peptides and proteins was a major advance both in understanding the mechanisms that trigger the disease and in its early diagnosis. Citrulline is a “nonstandard” amino acid that forms in the inflammatory environment as a result of the action of the enzyme peptidiliargininine deaminase on arginine residues present in proteins. Anti-citrullinated peptides are produced locally in the synovium of RA patients. The introduction of new immunoassays based on specially selected cyclic citrullinated peptides (CCP), allowed the development of tests with sensitivity equal to or better than traditional rheumatoid factor (RF), but with a much higher specificity. In addition to this, it was demonstrated that the presence of anti-CCP is both an early marker of AR (anti-CCP can be found up to 10 years before the onset of symptoms) and a marker of the severity of the disease. DIESSE is offering the new second generation anti-CCP Chorus kit to complete its line of tests for the serological diagnosis of systemic inflammatory diseases, in the convenient and pratical single determination format.
