Background: Chronic spontaneous urticaria (CSU) is a skin disorder with an important immunologic profile. S100A8, S100A9, and S100A12 are the members of S100 family that have been reported to play important role in autoimmune diseases, but the characteristics of these three S100 members have not been defined in CSU. Aims: This study was performed to investigate the levels of these three S100s in patients with CSU and to study whether they were associated with the severity and clinical characteristics of CSU. Materials and Methods: The levels of plasma S100A8, S100A9, and S100A12 were measured in 51 CSU patients and 20 healthy controls using enzyme linked immunosorbent assay kits. The values in the patient group and that of the healthy controls were statistically compared. The relationships between the different markers were evaluated by correlation analysis. Results: The plasma levels of S100A8, S100A9, and S100A12 were significantly higher in CSU patients than those in controls. Interestingly, the level of S100A12 was significantly correlated with S100A8 and S100A9 in CSU patients (P < 0.05 and P < 0.001, respectively). In addition, S100A8, S100A9, and S100A12 were all significantly inversely correlated with blood basophil percentage. Conclusions: Plasma S100A8, S100A9, and S100A12 levels were elevated in CSU patients. They might be useful biomarkers of CSU, with the potential role in the pathogenesis of CSU.
