Level of inflammatory cytokines tumour necrosis factor $\alpha$, interleukins 12, 23 and 17 in patients with psoriasis in the context of metabolic syndrome

Introduction: Psoriasis is a chronic inflammatory skin disease with immunologic etiology. Aim: To investigate the levels of the proinflammatory cytokines tumor necrosis factor \alpha ($TNF-\alpha$), interleukin 23 (IL-23) and IL-17 in patients with psoriasis and psoriatic arthritis with concomitant metabolic syndrome. Material and methods: This study included 60 patients with severe psoriasis. Results: In patients with arterial hypertension concomitant with psoriasis, no statistically significant differences in cytokine levels were observed. On the other hand, in the group of patients diagnosed with diabetes, an increased level of IL-17 was observed. In patients with lipid disorders, the results were similar to the results of patients with diabetes. Conclusions: It is very important to study immunologic mechanisms responsible for the presence and severity of psoriasis, in order to personalize the therapy in the future and optimize the effect of action on the basic disease and on concomitant disorders.
