ABSTRACT
BACKGROUND:
Acute urticaria is a common cutaneous disease encountered in children, while anaphylaxis can show cutaneous symptoms as well as systemic symptoms. One study found that urticaria tends to precede anaphylaxis, but studies on the different role of eosinophils and related cytokines in anaphylaxis and urticaria are lacking.OBJECTIVE:
The aim of this study was to compare the clinical features, total eosinophil count, serum levels of interleukin (IL)-18, IL-18 binding protein (BP), IL-1 receptor-like (RL) 1, and IL-33 and compare with tryptase to examine if any differences could be found between patients who experienced anaphylaxis and urticaria.METHODS:
We included 63 patients with urticaria and 52 patients with anaphylaxis. We measured total eosinophil count and the serum levels of total IgE, tryptase, IL-18, IL-18BP, IL-1RL1, and IL-33, and we compared the differences between the groups. Lastly, receiver operating characteristic curves were constructed to determine which factors accurately diagnosed anaphylaxis.RESULTS:
No significant differences were observed in the clinical characteristics or sensitization between urticaria group and anaphylaxis group. Laboratory findings showed that total eosinophil count and IL-18BP were significantly lower in the anaphylaxis group, compared with the urticaria group. IL-18BP showed significant correlation with tryptase. The receiver operating characteristic curve for IL-18BP for diagnosing anaphylaxis had an area under the curve of 0.530.CONCLUSIONS:
IL-18BP level was significantly different in patients with anaphylaxis compared to those with urticaria. Serum IL-18BP level may be used to differentiate between the patients with urticaria or anaphylaxis.
