Brief Summary

Myositis are rare diseases for which the development of a cohort associated with a bank of biological samples (biobank) will allow for the conduct of researches to better delineate the underlying pathophysiology and find cures. This prospective cohort of patients with myositis will allow for identification of factors favouring the occurrence of myositis, whether they are constitutional (genetic) or acquired (environmental or drug). Different subgroups of myositis used for prognostication will be identified based on clinico-demographical variables, the nature of the organs involved beyond peripheral muscles (cardiac, diaphragm) and biomarkers abnormalities

Outcome Measures

Primary Outcomes (1)

  • Characterisation of the different myositis subgroups based on clinical, radiological, electrophysiological and histobiological evaluations

    Characterisation of the different myositis subgroups based on clinical, radiological, electrophysiological and histobiological evaluations

    baseline: first 30 days after inclusion

Secondary Outcomes (38)

  • Characterisation of the natural history of myositis subgroups :responses to treatments, prognosis factors, evolution

    up to twenty years after inclusion

  • Characterisation of an immune system signature, using peripheral blood mononuclear cells and muscular biopsies, DNA and RNA sequencing, and autoantibodies

    baseline: first 30 days after inclusion

  • Risk factors for All-cause mortality depending on patient's and disease characteristics

    up to twenty years after inclusion

  • Change of the quality of life, using quality of life questionnaires, depending of patients and disease characteristics

    up to twenty years after inclusion

  • Change of activity impairment using an evaluation of daily life activity by both patient and physician using a Visual Analogue Scale depending of patients and disease characteristics

    up to twenty years after inclusion

  • +33 more secondary outcomes
