Brief Summary

Allergic rhinitis is a disease in which the nasal mucous membrane overreacts to allergens, resulting in symptoms such as spasmodic and repetitive sneezing, rhinorrhea, and stuffy nose, and can be treated with immunotherapy for radical treatment. Immunotherapy treatments include subcutaneous injections, sublingual tablets, and sublingual fluids, and subcutaneous injections have the risk of anaphylaxis, the hassle of daily administration at home, and local allergic reactions. Transdermal absorption immunotherapy (DF19001) that can compensate for the shortcomings of these existing immunotherapy drugs is currently under clinical research in Korea (Severance Hospital IRB No. 4-2021-1345). Immunotherapy requires periodic monitoring, such as analyzing immunological changes through sample collection and determining the dose and cycle of administration, because the treatment period is long and individual immune responses are different. Existing methods for confirming immune responses in samples used invasive skin biopsy and blood collection methods, but in-blood evaluation indicators have the disadvantage of being ineffective as initial efficacy evaluations or predictive evaluations before treatment. In addition, skin biopsy should be performed by a specialist, and there is a disadvantage that resistance occurs because the patient's pain is accompanied, and scars or bruises may remain. Therefore, since it is a biopsy through minimal invasion compared to a tissue biopsy, the investigators would like to use a method of collecting skin samples through a microstructure (micro needle patch), a method that has little pain and no scars. Through this study, RNA is obtained from patients with house dust mite allergic rhinitis through minimally invasive skin samples, and immunotherapy response evaluation biomarkers are screened according to immunotherapy implementation, and its use as an indicator of immunotherapy prognosis in allergic diseases.

Outcome Measures

Primary Outcomes (1)

  • Analysis of transcriptomic profiles based on RNA

    Based on RNA extracted from skin samples, transcriptomic profiles are analyzed to identify related RNAs that show meaningful changes compared to normal people and immunotherapy using heatmap, and it is estimated that Th2 or Treg-related RNA profiles will be significantly different

    4-6 months after baseline

Secondary Outcomes (1)

  • Differences in immunological efficacy by type of immunotherapy (subcutaneous, sublingual, percutaneous)

    4-6 months after baseline

Study Arms (2)

patient group of House dust mist allergic rhinitis

1. Adult male and female patients aged 19 to 60 with allergic rhinitis caused by the antigen of the American house dust mite (It is judged that the positive for the house dust mite is MAST ≥ Class 3 or ImmunoCAP® ≥3.5 kUA/L) 2. Moderate-severe persistent rhinitis when evaluated according to ARIA (Allergic rhinitis and its impact on asthma) 3. A person who has signed a written consent to participate in this clinical trial at his/her own discretion after fully explaining the purpose, contents, characteristics of the test drug, and expected adverse reactions prior to participation in the clinical trial

Other: Evaluation of clinical indicators, Sample collection before& after immunotherapy

control group

1. Adults 19 years of age or older who are judged to be free from skin diseases or allergic diseases through medical examination and visual observation by a specialist 2. A person who agrees to provide samples derived from the human body 3. A person who voluntarily agreed to this study and prepared a consent form after approval of the IRB

Other: Sample collection before& after immunotherapy

Interventions

A. Evaluation of clinical indicators before immunotherapy 1. Symptom Scale for Rhinitis: Total Nasal Symptom Score (TNSS), Rhnitis Quality of Life Questionnaire(RQLQ) 2. American house dust mite-specific immunogloblin G4 (sIgG4) 3. American house dust mite-specific immunogloblin E (sIgE) B. Sample collection before immunotherapy 1. Skin: Skin test using minimally invasive microstructure patch stripping method 2. Blood: Measurement of blood immunological indicators (Th2, Treg-related cytokine and blocking factor, etc.) C. Evaluation of clinical indicators 4 to 6 months after immunotherapy : Treatment is performed for about 4 months, and the progress of treatment is evaluated through the evaluation of the following clinical indicators. same as examination in 'A' D. Sample collection after 4 to 6 months of immunotherapy same as examination in 'B'
