Background: Fungal aeroallergens might sensitize the airway which in turn produces a specific cytokine profile. Objective: To evaluate the IL-25 and IL-33 profile in patients with fungal allergic rhinitis. Methods: The present study examined patients who were evaluated due to allergic rhinitis (AR) at Emam Reza Hospital of Shiraz, Iran. The allergic patients were categorized based on the skin prick test. Blood samples were collected and allergen-specific IgE and cytokine profiles were analyzed. Results: 184 patients were enrolled in the study and in 35 of whom fungal rhinitis was confirmed. The levels of specific IgE in patients with fungal allergy were statistically significant compared to those in the control group (p<0.000). However, there were no significant differences in IL-25 and IL-33 levels between fungal and none-fungal AR patients. Conclusion: Chronic fungal challenge might regulate innate system cytokines in severe persistent AR.

Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL-23 serum levels and its expression in persistent asthma compared with healthy children younger than five years old. Method: Blood samples of 40 children with mild and severe persistent asthma were compared to 34 healthy children regarding IL-23 serum levels and gene expression using enzyme-linked immunosorbentassay (ELISA) and real time quantitative polymerase chain reaction (PCR). Results: The IL-23 gene expression level was significantly different in the 25 children with mild persistent asthma and the 15 children with severe persistent asthma compared to the control group (p=0.001).There was no significant difference in IL-23 gene expression level between the two groups of patients with mild and severe persistent asthma. A significant difference was seen in IL-23 serum levels between the 25 children with persistent asthma and control group (p=0.002).Conclusion: For pre-school children with history and physical exam in favor of asthma which cannot be tested by spirometry, IL-23 serum levels may be an auxiliary biomarker for the diagnosis of asthma.
