Systemic Inflammatory Parameters in Patients with Elderly-Onset Rheumatoid Arthritis (EORA) and Young-Onset Rheumatoid Arthritis (YORA)-An Observational Study.

Background: Rheumatoid arthritis (RA) occurs more often in elderly individuals. Elderly onset RA (EORA) (onset > 60 years) encompasses a specific subset of patients if compared with young onset RA (YORA) (onset at a younger age). There is a need to define reliable, simple markers to properly assess the inflammatory activity of RA.

Rheumatoid arthritis (RA) is a systemic, autoimmune disease characterized by synovitis and irreversible joint destruction. RA development is a multi-stage process conditioned by the presence of genetic and environmental risk factors on the basis of which systemic immunization develops. The best known genetic factor predisposing to RA development is the polymorphism of HLA-DRB1 region of the major histocompatibility complex.
