Psoriasis is an immune-mediated skin disease that affects 1-2 % of the population. Several cytokines have been found to be involved in the complex pathogenesis of this disease. Il- 36 is one of the cytokines sharing in psoriasis pathogenesis, as its levels are elevated in psoriatic plaques. Cathepsin G is known to activate Il- 36 and promote inflammation in psoriasis.NB-UVB is one of the important treatment modalities for psoriasis.
The aim of this study is to detect the effect of NB-UVB on the lesional levels of IL-36 in psoriasis.
25 psoriasis patients will receive 26 sessions of phototherapy (NB-UVB). Patients will receive 3 sessions per week. Tissue levels of IL-36 and Cathepsin G will be assessed in skin lesions before starting treatment and after completing the 26 sessions.
