Clean Air for Asthma and Allergy Programme (CAAP), a randomized controlled trial to evaluate the effectiveness of multicomponent interventions to reduce indoor triggers in childhood asthma.
Background: Multicomponent interventions have been reported as effective strategies for improving allergen reduction and asthma control. However, few studies have evaluated the integration of an indoor air quality (IAQ) system and e-health as part of multicomponent interventions.
Objective: To evaluate the effects of multicomponent interventions on house dust mite allergens, indoor particulate matter, and knowledge and trigger reduction behaviors (TRBs) of caregivers.
Methods: Twelve pediatric asthmatic patients with dust mite sensitization were randomly assigned to either a multicomponent intervention group or a control group. In the multicomponent intervention group, IAQ systems were installed in participants' bedrooms, bedding covers were provided, and asthma education was delivered through the LINE application, while the control group received conventional treatment. House dust mite allergen levels were analyzed using the enzyme-linked immunosorbent assay technique, and particulate matter <2.5 micrometer diameter (PM2.5) concentrations were measured at baseline, 4 weeks, and 8 weeks postenrollment. Questionnaires were used to evaluate TRBs and asthma knowledge among caregivers before and after the intervention.
Results: There were decreased Dermatophagoides pteronyssinus allergen group 1 and Dermatophagoides farinae allergen group 1 levels in the multicomponent intervention group compared to the control group; however, the reduction was not statistically significant. Indoor PM2.5 concentrations were significantly lower in the multicomponent intervention group compared to the control group after 4 and 8 weeks (P = 0.005). Statistically significant improvement in overall TRBs (P = 0.04) and a trend in improving asthma knowledge among caregivers were observed in the multicomponent intervention group compared to the control group, although the difference did not reach statistical significance (P = 0.06).
Conclusion: Implementation of an IAQ system and asthma education through the LINE application, as part of multicomponent interventions, resulted in a significant reduction in indoor PM2.5 concentrations and improved TRBs among caregivers.
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.
