Research topic



Reumathoid Arthritis (RA) is one of the most common autoimmune diseases (1-2% European population). The most significant clinical symptom is an inflammation of the synovial membranes which causes a painful swelling of the articulations and the ankylosis. In order to correctly diagnose RA it is necessary to exclude other forms of arthritis: in this diagnostic process, the laboratory plays an important role in the determination of Rheumatoid Factor (RF) antibodies of class IgM, detectable in 60-80% of the patients with RA. The RF antibodies are sensitive but not very specific markers. On the contrary, anti citrullinated peptides (CP) autoantibodies are a hallmark of RA and are used in diagnostic assays, through the use of citrullinated sequences (such as: filaggrin and filaggrin derived cyclized peptides, citrullinated recombinant vimentin, fibrin, viral citrullinated proteins) as antigens. DiaMetra Anti CP IgG assay is based on viral and human citrullinated peptidic sequences that are used as antigens; this combined use allows to detect different subgroups of anti CP antibodies in the same set of patients, leading to a better diagnostic investigation.
