Role and Clinical Significance of Il-33 in Patients with Asthma

Introduction. Asthma is a chronic inflammatory disease of the airways in which many cells play a role with secreting a variety of mediators responsible for the clinical manifestation of asthma. It is assumed that IL-33 is one of the earliest-released mediators and can orchestrate the immune cascade of the disease. The aim of this study was to examine the role and clinical significance of IL-33 as a new and insufficiently explored mediator of inflammation in patients with uncontrolled moderate asthma. Methods. The study included 87 patients with asthma. Serum IL-33 was measured in all patients by ELISA method. The obtained data were statistically analyzedusing the Kolmogorov-Smirnov and Shapiro-Wilk's test. Qualitative data were presented in absolute and relative numbers, and quantitative data were presented with measures of descriptive statistics. Statistically significant values were considered forp Results. Majority of included patients were female (75.86%). The average age of patientswas 42.3±15.9 years. The results of IL-33 in all patients were significantly increased compared to the reference value of IL-33 which is 0pg/ml. The average values of IL-33 ranged from 6.47±29.3 and they were insignificantly higher in the group with female patients compared to males (p=0.27), and insignificantly correlated with age (p=0.26). Conclusion. Even though a limited number of studies haveexplored the IL-33, results have shown higher serum level of IL-33 in asthma patients compared to healthy people, emphasizing the factthat IL-33 is an attrac tive candidate for targeted therapy and prognosis inasthma patients.
