Rheumatoid arthritis (RA) is characterized as a systemic auto immune disorder linked to a persistent inflammatory process that can harm both joints and extra articular organs.
The upregulation of the CCR6/CCL20 axis in the synovial tissues and salivary glands (in cases of secondary Sjögren's syndrome) is considered to contribute to the recruitment of Th17 cells, which in turn enhances IL 17A production and promotes the inflammatory cycle.
Adults (18-60 years) diagnosed with RA according to the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2010 classification criteria for RA by an expert rheumatologist.
• Patients with co-existing infections or other autoimmune diseases.
