IL6 and urticaria: Analysis including all patients with urticaria showed a positive correlation between IL-6 concentration and white blood count (WBC) (r = 0.21, p = 0.03), neutrophil-to-lymphocyte ratio (NLR) (r = 0.2, p = 0.04) and neutrophil count (r = 0.2, p < 0.05) and IL-17A concentration and CRP (r = 0.35, p < 0.001).
