Characterisation of articular manifestations in primary Sjögren's syndrome: clinical and imaging features

Articular manifestations (AMs) are observed in a large proportion of patients with primary Sjögren's syndrome (pSS) and can occur at the time of pSS diagnosis or during the disease course. Although in the majority of cases AMs are mild and self-limiting, some patients may experience chronic polyarthritis requiring treatment with DMARDs. Ultrasonography (US) and magnetic resonance imaging (MRI) can help assessing the extent of articular involvement and guide the treatment. The aim of this study was to describe clinical, serological, and histological picture of a cohort of pSS patients with AMs.
