HAMBURG, Germany, June 11, 2023 /PRNewswire/ -- A study conducted by researchers from the ALL-MED Medical Research Institute and the Department of Clinical Immunology at Wroclaw Medical University in Poland has validated the use of an allergen exposure chamber (AEC) in assessing the clinical outcomes of house dust mite (HDM) allergen immunotherapy (AIT) in patients with allergic rhinoconjunctivitis. The study focused on evaluating the efficacy and safety of AEC-derived clinical outcomes of subcutaneous HDM AIT, a treatment designed to alleviate symptoms triggered by HDM allergies. Fifty patients with HDM-triggered allergic rhinoconjunctivitis were included in the study, with HDM allergy confirmed through various diagnostic tests such as skin prick tests, serum-specific IgE, and basophil activation tests. During the study, patients were assessed in the allergen exposure chamber before commencing AIT and after 12 months of treatment. The chamber provided a controlled environment, allowing patients to be exposed to HDM allergen under stable and well-regulated conditions. Various clinical endpoints, including total nasal symptom score (TNSS), visual analog scale (VAS), and objective parameters such as acoustic rhinometry, peak nasal inspiratory flow (PNIF), and nasal secretion weight, were used to assess the effectiveness of AIT.
The results of the study demonstrated a statistically significant reduction in TNSS (phttps://review.jove.com/v/64801?status=a66807k
In conclusion, the study confirms that the allergen exposure chamber challenge is an effective, reproducible, and safe method for assessing the outcomes of HDM AIT in patients with allergic rhinoconjunctivitis. Ongoing research is being conducted to validate clinical endpoints using immunological biomarkers, offering promising prospects for improved diagnostic and treatment approaches. The European Academy of Allergy and Clinical Immunology (EAACI) is an association of clinicians, researchers and allied health professionals founded in 1956. EAACI is dedicated to improving the health of people affected by allergic diseases. With more than 15 000 members from 125 countries and over 75 National Allergy Societies, EAACI is the primary source of expertise in Europe and worldwide for all aspects of allergy.
