Psoriasis
Conditions
Brief summary
Psoriasis is an immune-mediated inflammatory skin disease characterized by the presence of erythematous and itchy plaques. Psoriasis has a multifactorial pathogenesis, environmental and genetic factors contribute to its development. Although interleukin-23 blockade has been shown to be highly effective in the treatment of psoriasis, relapses have occurred during therapy. Our study aims to identify the cellular source of key cytokines involved in disease recurrence or persistence of at least one psoriatic lesion in patients affected by moderate- severe psoriasis treated with an anti-IL-23 biologic drug. The immune infiltrate of resistant or relapsed plaques during anti-IL-23 therapy will be analysed from skin biopsies.
Interventions
punch biopsy (6 mm) of lesional psoriasis skin

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Identify the cellular source of key cytokines involved in disease recurrence or persistence of at least a psoriatic lesion | through study completion, an average of 1 year | Through the integration of multiparametric immunofluorescence staining with RNA in situ hybridization technology, our study aims to identify the cellular source of key cytokines involved in disease recurrence or persistence of at least one lesion psoriatic lesion in patients with moderate-severe psoriasis, undergoing treatment with anti-IL-23. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| immune biomarkers of sustained and prolonged response to treatment | through study completion, an average of 1 year | Identification of possible immune biomarkers of sustained and prolonged response to anti-IL-23 biological therapy that will include the expression profile of biomarkers related to tissue immune memory. |
