Serum Level of Selenium, IL-4, IL-10 & IFN-g in Patients with Allergic Asthma, Allergic Rhinitis and Healthy Controls
Authors
Abstract:
Background: Allergic diseases have increased during the past decade worldwide. Th2 type lymphocyte response is known to play an important role in the process of allergic inflammation. IL-4, a mediator of type II cytokine response increases IgE synthesis and Interferon gamma, a cytokine of type I response interferes with IL-4 and inhibits IgE production. Selenium is an essential component of glutathione peroxides and changes in its plasma level has been proposed to be associated with allergic diseases. Materials and Methods: This study comprised of 21 cases of allergic asthma (AA), 33 cases of allergic rhinitis (AR) whose age and sex were matched with 28 healthy controls. IL-4, IL-10, IFN-g levels were tested by ELISA assay, and serum selenium was measured by atomic absorption spectorphotometery method. Results: Mean serum selenium level of AA and AR groups were lower than controls. Mean serum IL-4 level of AA was higher than the AR group. Mean serum IL-4 level of AA and AR group were higher than controls. Conclusion: The results of this study indicate that low selenium level may have a role in the pathogenesis of allergic diseases.

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 all...

immune and inflammatory responses mediated by cytokines, play important roles in the pathophysiology of asthma. these responses are associated with overexpression of th2 cytokines such as il-4 and il-13. these two cytokines use common receptors for signaling that lead to identical immunological effects and regulation of the th1/th2 balance. the aim of this study was to determine whether patient...

Background : Allergic asthma is a chronic inflammatory disease of airway that often determined with degrees of inflammation, hypersensitivity, bronchial constriction and airway changes. Th1, Th2 and Th17 cells are the main cells involved in the pathophysiology of asthma. . Therefore, this study evaluated Th1, Th2, and Th17 cells functions by assessment the expression of INF-g, IL-4, and IL-17 g...

BACKGROUND AND OBJECTIVE Interleukin (IL) 4 is a cytokine that mediates allergic responses. Different single nucleotide polymorphisms (SNPs) can influence the immune response mediated by cytokines. The aim of the present study was to investigate the possible association between IL-4 polymorphisms and allergic rhinitis and atopic asthma. METHODS A total of 214 atopic patients (108 with asthma ...
