- Alternative Abstract
- Background and Purpose: Allergic rhinitis (AR) is a common and increasing allergic disease, in which Dermatophagoides (D.) farinae is the most common causative allergen. The aims of this study are to compare locally produced antibodies to D. farinae in nasal mucosa between nasal provocation test (NPT)-positive and NPT-negative groups on NPT for D. farinae, to evaluate their correlation with the levels of inflammatory mediators, and to determine adaptive and innate immune responses in nasal mucosa. Subjects and Methods: Sixty AR patients underwent NPT for D. farinae. The sinus packs were placed in both nasal cavities of the patients for 5 minutes to obtain nasal secretion after NPT. The levels of total IgE, specific IgE to D. farinae, ECP, and tryptase were measured by using ImmunoCAP. Specific IgE, IgA to D. farina, and secretory IgA antibodies were measured by using ELISA. IL-8, VEGF, IL-25, and IL-33 levels were also measured by using ELISA Results: The high levels of total IgE, specific IgE, specific IgA, and secretory IgA, as well as inflammatory mediators, such as ECP, IL-8, VEGF and tryptase, were detected in nasal secretion, although the differences were not statistically significant between the NPT-positive and NPT-negative groups. The levels of total IgE, specific IgE to D. farinae, specific IgE, IgA to D. farina, and secretory IgA correlated with ECP (r=0.757, 0.436, 761, 0.737 and 0.692, respectively; all p<0.001). IL-33 and IL-25 were also highly detected, and IL-25 significantly correlated with IL-8 (r=0.625, p<0.001). Compared to the ELISA method, the ImmunoCAP system was more sensitive in the detection of specific IgE to D. farinae. Differences between right and left nasal secretions had no statistical significance. Conclusion: These findings confirmed the presence of locally produced specific antibodies to D. farinae in nasal secretion obtained from D. farinae-sensitive AR patients in which close correlations were noted between the antibodies and nasal inflammatory responses. It is suggested that both innate and adaptive immune responses may be involved in nasal inflammation of AR patients.
