ABSTRACT
OBJECTIVE To explore the correlation of allergic rhinitis symptoms in preschool children with the household environment dust mites and house dust-mite-specific IgE, as to provide theoretical basis for pediatric allergic disease prevention and control work. METHODS The children with rhinitis who was born in the Second People's Hospital of Wuhu were selected in this study. When the children were 3 or 4 years old, they were followed up. The allergic rhinitis symptoms integral of the children were evaluated, the household environment dust samples of the children were collected. The content of dermatophagoides pteronyssinus allergen components 1(Der p1) and dermatophagoides farinae allergen components 1(Der f1) in dust samples were determined by the method of enzyme-linked immunosorbent(ELIEA). The children house dust-mite-specific serum IgE(sIgE) level was also examined. RESULTS Pediatric allergic rhinitis symptoms had a positive correlation with dermatophagoides pteronyssinus sIgE and dermatophagoides farinae sIgE(P0.05). CONCLUSION The allergic rhinitis symptoms of the children are positively correlated with household environment dust mites and dust mites specific IgE. That indicated the severity of allergic rhinitis symptom in children may be determined by detecting specific IgE levels. The prevention of allergic disease and improvement the quality of life of the allergic children can be done by strengthening the health education of dust mites and decreasing the content of bedroom environment dust mites.
ABSTRACT
OBJECTIVE@#To observe the household environment dust mites allergens content distribution characteristics and influence factors of children with allergic rhinitis to dust mites in Wuhu.@*METHOD@#Collect the surface dust in bedroom and living room floor, mattresses, pillows, sofa of 102 children with allergic rhinitis families. Dust mite allergen components 1 (Der f1) and house dust mites allergens 1 components (Der p1) of the dust samples were determined by enzyme-linked immunosorbent assay (ELISA).@*RESULT@#One hundred and twenty samples were collected . In a domestic dust mites samples, with a median of M (Min and Max) said dust mite allergen levels, Der f1 and Der p1 content was 2.66 (0.03, 26.63), 3.48 (0, 03, 33.68), respectively. Der f1 was significantly less than Der p1, and the difference was statistically significant (P 0.05).@*CONCLUSION@#The household dust mites of children allergic rhinitisin Wuhu area is given priority to with Der p1, and urban dust mites are significantly more than village's and town's. Enhancing health education, controlling dust mites allergens contamination inside the bedroom, especially urban areas, are positive differences for the prevention and treatment of allergic diseases such as allergic rhinitis in children.
