The AMISS study will characterize the features of muscle disease in patients with primary Sjogren's syndrome (pSS).
Condition or disease
Primary Sjögren Syndrome
Muscle disease is associated with pSS, but this association is not well defined. The AMISS study, a retrospective observational multicentric study, will recruit patients with pSS and muscle involvement in order to characterize in details the features of this association (epidemiological aspects, clinical presentation, biological, radiological and histological findings, treatments and outcomes).
