Answer

Articular changes (eg, arthritis) occur in 42% of patients with Sjögren syndrome; arthritis can be a component of either the primary or secondary form of the disease. One third of patients with RA have Sjögren syndrome.

Symmetrical, polyarticular, inflammatory arthritis suggests underlying RA or a connective-tissue disease such as SLE or scleroderma. The arthritis in patients with primary Sjögren syndrome is typically nonerosive and mild.
