Abstract
PURPOSE: Allergic rhinitis (AR) is a common and increasing disease in which Dermatophagoides (D.) farinae is one of the most common causative allergens. The aims of this study were to confirm the presence of locally produced antibodies to D. farinae in nasal secretions between nasal provocation test (NPT)-positive and -negative groups of AR patients, to evaluate their relationships with the levels of inflammatory mediators, and to determine adaptive and innate immune responses in nasal mucosa. METHODS: Sixty AR patients sensitive to house dust mites confirmed by skin prick test or serum specific IgE to D. farinae underwent NPT for D. farinae. Nasal packs were placed in both nasal cavities of the patients for 5 minutes to obtain nasal secretions after NPT. The levels of total IgE, specific IgE to D. farinae, eosinophil cationic protein (ECP), and tryptase in nasal secretions were detected by using ImmunoCAP. The levels of specific IgE, IgA, and secretory IgA antibodies to D. farinae in nasal secretions were measured by using ELISA. The levels of IL-8, VEGF, IL-25, and IL-33 were also measured by using ELISA. RESULTS: High levels of total IgE, specific IgE, specific IgA, and secretory IgA to D. farinae, as well as inflammatory mediators, such as ECP, IL-8, VEGF and tryptase, were detected in nasal secretions, although the differences were not statistically significant between the NPT-positive and NPT-negative groups. Levels of all immunoglobulins measured in this study significantly correlated with ECP, IL-8, and VEGF (P<0.05), but not with tryptase (P>0.05). IL-33 and IL-25 were also detected, and IL-25 level significantly correlated with IL-8 (r=0.625, P<0.001). CONCLUSIONS: These findings confirmed the presence of locally produced specific antibodies, including D. farinae-specific IgE and IgA, in nasal secretions collected from D. farinae-sensitive AR patients in both the NPT-positive and NPT-negative groups, and close correlations were noted between antibodies and nasal inflammatory mediators, including such as ECP, IL-8 and VEGF, indicating that locally produced antibodies may be involved in the nasal inflammation of AR.
