Systemic lupus erythematosus is a complex systemicautoimmune disease that can affect most organs of the human body. Although they are many recommendations on the diagnosis and managment of SLE, diagnosis and therapeutic managment is still challenging. A pluridisciplinary consultation grouping rheumatologist, nephrologist, dermatologist, gynecologist, internist and immunologists has been set up in 2009 at the university hospital of Brest. The investigators would like to identify in a longitudinal cohort the occurrence of the different clinico-biological and immunological patterns of systemic lupus erythematosus patients during our multidisciplinary consultation. It is now crucial to organize a standardized data collection of these patients in order to evaluate our pratices, to be able to study the epidemiology of SLE in our city, and to promote this initiative at national and international level.
