Overview
The aim of this project is to start a biological and clinical collection of patients presenting autoimmune, dysimmune or auto-inflammatory dermatological diseases. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies.
Description
Autoimmune diseases include around a hundred different clinical entities which are for the most part rare pathologies but which, in combination, concern 5-8% of the adult population with a strong female predominance (FAI²R: the disease chain rare autoimmune and auto-inflammatory drugs, fai2r.org). The common denominator of all these diseases is based on the breakdown of self-tolerance which is the origin of self-reactivity and whose physiopathological mechanisms are still not fully understood, which generates numerous cross-sectional or fundamental studies. In addition to this complexity, there are significant inter-individual variabilities which lead to the definition of subgroups of patients on the basis of the clinical-biological profile and / or the response to treatments. Consequently, and in view of the need to establish the diagnosis early and then to propose the best treatment in the perspective of an individualized medicine, the clinical, biological and genetic characteristics of these subgroups of patients must be explored in order to improve diagnostic and therapeutic capacities.
Eligibility
Inclusion Criteria:
Skin damage of documented or probable autoimmune, dysimmune or autoinflammatory origin.
The patients included may be adults or children, and will be:
- Patients with autoimmune bullous dermatoses (pemphigus, pemphigoid and others),
- Patients with systemic autoimmune diseases associated with skin damage (lupus, scleroderma, dermatomyositis for example),
- Patients with cutaneous lupus
- Patients with dysimmune skin diseases (psoriasis, eczema)
- Patients with immuno-induced dermatological disorders or drug dermatitis
- Patients receiving, or likely to receive, new, innovative therapies (new molecule on the market, checkpoint inhibitors, gene therapy, cell therapy, etc.).
Patients with dermatological damage whose autoimmune, dysimmune or auto-inflammatory origin
is suspected
Exclusion Criteria:
- Patients under protective supervision (guardianship, curators)
- Patients under 6 years old
- Pregnant or breastfeeding woman
