About this study

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).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • diagnosis of Primary Sjögren's syndrome according to the ACR/EULAR classification criteria
  • inflammatory muscle involvement, as diagnosed by the treating physician

Exclusion criteria

  • Diagnosis of inflammatory myopathy before the diagnosis of pSS

Treatment and study plan

Primary outcomes

  1. Proportion of patients fulfilling classification criteria for inflammatory myopathies

    Time frame: At diagnosis

    Among the patients included in the AMISS study, we will assess the proportion of patients who fulfill the classification criteria for the different inflammatory myopathies.
