Elevated plasma il-8 concentration is related to severity of systemic inflammation in chronic spontaneous urticaria
Vol 31, Issue 4, 2017
Abstract
Chronic spontaneous urticaria (CSU) is associated with activation of acute phase response. Questions arise regarding its association with other inflammatory mediators. To determine plasma IL-8 concentration in CSU patients and its association with C-reactive protein (CRP) concentration, a nonspecific inflammatory marker of the disease activity, concentrations of plasma IL-8 and serum CRP were measured in CSU patients and compared with healthy controls. IL-8 and CRP concentrations were significantly higher in CSU patients as compared with the healthy subjects. In addition, there were significant differences in IL-8 and CRP concentrations between CSU patients with moderate-severe symptoms and the healthy subjects. Plasma IL-8 and serum CRP concentrations showed a significant correlation with urticaria activity score (UAS). Additionally, a significant positive correlation was observed between IL-8 and CRP concentrations. Up-regulations of IL-8 and its association with the marker of clinical and inflammatory activity suggest a role of this cytokine in the pathogenesis of CSU.
