Abstract |
Background and Objectives To evaluate IgE reactivity profiles to Der p 1, Der p 2, and Der p 10 in house dust mite (HDM) allergic rhinitis (AR) patients in Korea. Symptomatic and serologic changes after sublingual immunotherapy (SLIT) were analyzed according to IgE profiles. MATERIALS AND METHODS Sixty AR patients diagnosed with an HDM allergy were tested for the presence of IgE antibodies against purified HDM allergen molecules (i.e., nDer p 1, rDer p 2, and rDer p 10) and native Dermatophagoides pteronyssinus (Dp) using ImmunoCAP 250®. Symptom scores and laboratory findings were analyzed after SLIT. Results Prevalence rates of IgE for Dp, Der p 1, Der p 2, and Der p 10 were 100%, 98.3%, 93.3%, and 8.3%, respectively. After one year of immunotherapy with SLITone○R (standardized to major allergens, but not Der p 10), symptom scores and laboratory findings improved in patients with and without Der p 10 IgE antibodies. Conclusion In Korean AR patients, specific IgE antibodies to Der p 1 or Der p 2 are present in most Dp-allergic patients, while reactivity to Der p 10 is very low. Allergic symptoms improved in patients with Der p 10 IgE antibodies after SLIT. |
