Clinical Trial Summary

We will perform double-blinded placebo-controlled randomized clinical trial which evaluates the efficacy and safety of allergen-specific intralymphatic immunotherapy (ILIT) for allergens including Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), cat, and dog that are sensitized and provoke rhinitis-related symptoms in patients with allergic rhinitis.


Clinical Trial Description

After informed consent, subjects will be randomly assigned to ILIT group or placebo group in double-blind manner. In both group, causal allergen or placebo will be injected into inguinal lymph node through guidance by ultrasonography three times with 4-week interval. In ILIT group, initial dose of allergen will be 1,000-fold diluted solution from maximal concentration of allergen extract for subcutaneous immunotherapy (30 AU/ml for Df or Dp, 10 AU/ml for Cat hair, and 1:1/10 weight/volume for dog hair/dander, HollisterStier, New Orleans, USA) in volume of 0.1ml. If skin is highly reactive in skin prick test, the initial dose will be 10-fold dilution from maximal concentration where diameter of wheal is less than that of histamine. After the first dose, allergen concentration will be escalated 3-fold at second dose, and 10-fold at third dose if there are no local or systemic hypersensitivity reaction. The allergen concentration will not change at second or third dose if there is mild local or systemic reaction. The allergen concentration will decrease by 10 or 100-fold from previous concentration or further injection will be holded if there is severe local or systemic reaction after sufficient explanation and discussion with subjects.

The investigators will evaluate allergic rhinitis symptom score before and 4, 12 months after the initial treatment. Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and Sino-Nasal Outcome Test (SNOT-20) will be used. Visual analogue scale (VAS) of symptoms including rhinorrhea, sneezing, nasal obstruction, postnasal drip, eye/nose/ear/palate itching, dyspnea, wheezing, chest discomfort as well as urticaria, angioedema, and itching on exposed skin during exposure to causal allergen in daily life will be also evaluated. Skin prick test, intradermal test, blood sampling for serum allergen-specific IgE, exhaled nitric oxide, and nasal lavage for Th1, Th2, and Treg cytokines will be also performed before and 4, 12 months after the initial treatment.

Adverse events will be recorded and graded according to Muller classification and Ring and Messner classification. ;
