NCT05868824

Brief Summary

This is a prospective, single-center, class 2 study to better characterize the immune response in immune response in the blood of atopic dermatitis. Investigators are following in the referral center of Nice, 100 patients with atopic dermatitis. Investigators plan to include 30 patients. Blood samples will be collected to assess cytokine levels after non-specific immune stimulation. immune stimulation. Whole blood will be collected and stimulated with immune ligands (anti-CD3 T-cell stimulating ligands associated with Thymic Stromal LymphoPoietin (TSLP) or TLR agonist R848 7/8 agonist stimulating NK (natural killer) lymphocytes and promoting T cell response) on lyophilized freeze-dried spheres (LyoSphere, Qiagen) within 8 hours of blood collection.

Outcome Measures

Primary Outcomes (2)

  • Compare the dynamic blood cytokines profile by stimulating blood with immune ligands

    Cytokines dosage, measured by ELISA, in blood sample before and after in vitro stimulation with immune ligands at baseline. Responders are defined by an Investigator's Global Assessment score £ 1, and by 2 or more points improvement.

    At baseline

  • Compare the dynamic blood cytokines profile by stimulating blood with immune ligands

    Cytokines dosage, measured by ELISA, in blood sample before and after in vitro stimulation with immune ligands after 3 months of treatment. Responders are defined by an Investigator's Global Assessment score £ 1, and by 2 or more points improvement.

    After 3 months

Secondary Outcomes (1)

  • Compare cytokine dosage according to the different phenotypes of patients with atopic dermatitis.

Other: Blood sample

Interventions

A blood sample for assessing cytokines will be performed at baseline and at follow-up visit 3 months after initiation of treatment. The blood sample will be performed as part of blood tests done for standard AD follow up.
