Main level of cytokines in patients with psoriasis
Abstract
The aim of the study was to determine the level of cytokines in the serum of patients with psoriatic arthritis (PsA) and psoriasis vulgaris (Ps) and to identify key immune markers associated with clinical manifestations of psoriasis. Materials and methods. The study involved 52 patients with psoriatic arthritis (PsA) and 20 patients with psoriasis vulgaris (PS) by multiplex analysis of proteins using Bio-Plex device and commercial test kits 23-Plex and 27-Plex, 8-Plex. Assessment of the severity and prevalence of psoriatic skin lesions in patients was conducted by index PASI (Psoriasis Area and Severity Index). Indicators of acute-phase activity (ESR, CRP), CEC were defined in all patients. the comparison group consisted of patients with a diagnosis of patchy scleroderma (10 patients) and patients with atopic dermatitis (10 patients). 13 healthy individuals were examined as a control group. Main results. Significant elevation of cytokines: IL-2, IL-6, GM-CSF, IFN-y and TNF-a was found in the serum of patients with PS compared with the group of apparently healthy individuals, and GM-CSF, IFN-y compared with patients with atopic dermatitis. It was determined that the detected levels of Il-В in serum has a direct correlation with the prevalence and severity of PS. Inverse correlation between ESR and the level of IL-8, GM-CSF and the CEC, IFN-y and the CEC and the direct correlation between the level of TNF-a and CRP in serum were shown. Conclusion. The obtained data indicate shifts in the system of pro-inflammatory and anti-inflammatory cytokines in psoriasis, which can be considered as a manifestation of endogenous homeostatic mechanisms designed to limit the intensity of the inflammatory process. Immune markers associated with clinical manifestations of psoriasis, in particular, the prevalence and severity of PS (index PASI), indicators of acute-phase activity (ESR, CRP), were identified.
