Sumario:Acute infectious urticaria, a subset of acute urticaria, with severe persistence wheals and systemic symptoms, response well to corticosteroids treatment in combination with antibiotics. The exact pathogenic mechanisms are not fully understood. In this study, we aim to analyze the different clinical features, compare the level of neutrophil activation, and investigate the expression of inflammatory related cytokine in patients with acute urticaria and acute infectious urticaria. Eighteen patients with acute infectious urticaria and eighteen patients with acute urticaria were included in this study. We analyzed the difference between the clinical features and the serum expressions of pro-inflammatory factors in the two groups, then examined the levels of inflammation-associated cytokines before and after treatment of acute infectious urticaria. Hematoxylin & eosin (HE) staining and immunohistochemistry (IHC) were used to further study the relationship between neutrophil and neutrophil-derived Myeloperoxidase (MPO) of lesions in the two groups. The expression levels of C-reactive protein (CRP), D-dimer, interleukin 6 (IL-6), IL-8 and chemokine ligand 8 (CCL8) in serum were significantly higher in acute infectious urticaria than acute urticaria. In acute infectious urticaria, the serum expression levels of CCL8 were significantly decreased after the treatment, a significant correlation observed between CRP levels and IL-6, both CCL8 and CRP were positively correlated with neutrophil granulocytes. Neutrophils infiltration were not observed by HE stains in two groups, but in IHC stains we found a positive expression of MPO in acute infectious urticaria lesions. Elevated neutrophil in the serum, which is associated with the levels of IL-8 & CCL8, and positively expressed MPO in lesions, may be involved in the pathogenic mechanism of acute infectious urticaria.
