ABSTRACT
BACKGROUND:
Psoriasis is an autoimmune skin disease characterised by proliferation of keratinocytes, primarily due to cytokines Th1 and Th17. This profile is involved in pathogenesis of metabolic syndrome, a frequently found comorbidity in patients with psoriasis.OBJECTIVE:
In this study we determine the correlation of levels of pro-inflammatory cytokines TNF-α, IL-23, IL-12, and IL-22 in patients with psoriasis with and without metabolic syndrome and clinically healthy controls.METHODS:
We included 55 patients with plaque psoriasis 30 with metabolic syndrome (PPMS), 25 without metabolic syndrome (PP), 15 healthy subjects (HS) and 15 with metabolic syndrome (MS). Quantification of serum levels of IL-12, TNF-α, IL-22, and IL-23 was done by ELISA.RESULTS:
We observed that serum levels of IL-12 were more elevated in PP group, while the lowest levels of TNF-α were seen in HS group. IL-22 was found to be higher in PP than in PPMS (p<0.05). PP patients with PASI scores rating as severe showed higher levels of IL-12. TNF-α level analysis showed significant differences in HS group compared with the others; levels of this cytokine were lower in patients with PP and moderate PASI scores than in MS group (p<0.05). We found no correlation between cytokine levels and psoriasis or between cytokines and PASI scores. In PP group, a positive correlation was observed between IL-23 and fasting glucose (r=0.432, p<0.05), as well as a negative correlation between IL-23, IL-22, and IL-12 versus waist circumference (r=-0.504, r=-0.556 and r=-0.511, respectively; p<0.05).CONCLUSIONS:
Psoriasis is not just a skin disorder, but rather a condition with systemic implications, with intervention of pro-inflammatory cytokines that contribute to metabolic syndrome and other comorbidities, which in turn increases the risk of developing cardiovascular disease.Palavras-chave
