About the trial
What the trial wants to find out
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.
