Abstract
Background: House dust mites (HDM) are the major causative allergen for allergic rhinitis. The sole disease-modifying therapy for allergic rhinitis is allergen immunotherapy (AIT). Rush immunotherapy is the accelerated build-up schedules to reach the target maintenance dose.
Objective: To evaluate the kinetic changes of peripheral blood CD4+CD25+FOXP3+ regulatory T cells (Treg) and serum cytokines in children undergoing 2-day modified rush HDM AIT.
Methods: Children aged 5-15 years with allergic rhinitis were enrolled for a 2-day modified rush HDM AIT. Peripheral blood CD4+CD25+FOXP3+ Treg, serum interleukin (IL)-4, IL-13, interferon-γ, and IL-10 were measured at baseline, finishing rush, achieving maintenance dose, 6 months, and 12 months after reaching maintenance dose. Specific IgE (sIgE) to HDM was evaluated at baseline and 12 months after getting the maintenance dose. Rhinitis symptoms were assessed daily using a daily card.
Results: A total of 12 children with a mean age of 13 years were enrolled. Rhinitis symptom-free days per month increased significantly after reaching the maintenance dose compared to baseline (from 9.5 days to 19.5 days, p = 0.002), and the maximum improvement was seen at 1 year. The levels of Treg were significantly increased at 6 months after maintenance dose compared to baseline level (6.27%±1.63% vs. 3.83%±1.80%, p < 0.001). After treatment, there were significantly decreased serum IL-13 at 1 year after maintenance but no significant changes in sIgE to HDM. The systemic reaction during AIT occurred 7 episodes from 119 shots (5.9%).
Conclusion: Two-day modified rush HDM AIT provides acceptable systemic reactions and increases the number of CD4+CD25+FOXP3+ Treg in children.
期刊介绍:
Asia Pacific Allergy (AP Allergy) is the official journal of the Asia Pacific Association of Allergy, Asthma and Clinical Immunology (APAAACI). Although the primary aim of the journal is to promote communication between Asia Pacific scientists who are interested in allergy, asthma, and clinical immunology including immunodeficiency, the journal is intended to be available worldwide. To enable scientists and clinicians from emerging societies appreciate the scope and intent of the journal, early issues will contain more educational review material. For better communication and understanding, it will include rational concepts related to the diagnosis and management of asthma and other immunological conditions. Over time, the journal will increase the number of original research papers to become the foremost citation journal for allergy and clinical immunology information of the Asia Pacific in the future.
