About this trial

Dendritic cells (DC) paly a key role in the induction and chronicity of psoriasis by capturing the antigenes and activating the T cell repsonse. This activation requires their migration from the cutaneous sensitisation site to the lymph nodes. This migration requires an important intracellular metabolic activity, with a strong involvmenet of glucdic metabolism. This activity is linked with the systemic activity. This study aims to compare the migration and the phenotypic and metabolic caracteristics of blood and skin DCs in patients with or without psoriasis and with or without type 2 diabetes,

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients of both sexes

hospitalized in the Dermatology department of the CHU of Nice for moderate to severe psoriasis (defined by a PASI > or = 10)

covered by a social security scheme after obtaining a free

Clinical diagnosis of plaque psoriasis by a dermatologist with or without type 2 diabetes (defined by glycated hemoglobin >7%)

Disqualifiers

Minor or incapable or unwilling to consent freely or in an informed manner Pregnant or nursing woman.

Patient in a period of exclusion from other biomedical research

Patient with generalized chronic inflammatory disease or other inflammatory dermatosis

Patients on general corticosteroid, immunomodulator or immunosuppressant therapy in the month prior to local inclusion or treatment with corticosteroid therapy in the 15 days prior to inclusion, on anti- treatmentIL-23 or anti IL12/23 for less than 3 months or under anti-IL-17 or anti-TNF treatment for less than 1 month.

Trial design

Design model

Single group

Treatments tested in this trial

  • Biopsy and venous blood

    Other intervention

    A skin biopsy will be performed under local anesthesia in diabetic and non-diabetic psoriatic patients (25 per group) in the injured area (joint extension) and in the non-injured area more than 2 cm from any lesion in the same area. In patients in the diabetic or non-diabetic control group (25 per group) only one biopsy will be performed. Peripheral venous blood will be collected in heparin tubes for metabolic parameter analysis and blood CD analysis
