About this trial

Chronic inflammatory skin diseases constitute a heterogeneous group of pathologies. They affect the skin but also other organs (joints, lungs, muscles, etc.). Their prognosis and response to treatments is extremely variable. The discovery of prognosis factors will help to precisely guide the treatment regimen and its intensification based on individual markers. The identification of new therapeutic targets is essential to develop new innovative treatments for inflammatory skin diseases.

The main objective is to identify new cellular or molecular prognostic factors associated with treatment response at 1 year in inflammatory skin diseases.

The secondary objectives are a better understanding of the pathophysiology of chronic inflammatory skin diseases, the identification of new cellular, molecular and microbiological prognostic factors associated with the clinical state after 10 years of evolution and the identification of prognostic markers of drug toxicity.
