Nghiên cứu tỷ lệ mắc và đặc điểm lâm sàng, cận lâm sàng của viêm mũi dị ứng ở trẻ hen phế quản

Objectives: The prevalence of allergic diseases, especially asthma and allergic rhinitis (AR), has dramatically increased during the last decades. We aimed to assess the incidence of AR in children with asthma from 6-15 years old and describe the clinical, subclinical characteristics of AR. Me.thod: prospective study, time from June 2011 to June 2012. Result: among 158 patient with asthma, 65.8 percent have AR. The clinical charateristics of AR were: running nose (100.0 percent), sneezing (95.2 percent), itchy nose (74.0 percent). 100 percent of these symptoms occurred when climate change, 68.3 percent in spring, 62.5 percent in winter. 69.2 percent AR patients were mild. The subclinical: 47.4 percent patients had increasing eosinophil over 5 percent. 23.1 percent had increasing IgE. The common inhalant allergens were: D. pteronyssinus (46.9 percent), D. farinae (43.8 percent), dog (21.9 percent), cat (21.9 percent), cockroach (9.4 percent), mouse (3.1 percent). Conclusion: the incidence of AR in children with asthma was 65.8 percent. The most common symptoms were running nose, sneezing, itchy nose. Almost AR patients were mild. The sensitization to common inhalant allergens was high.
