2.An Ecological Study on the House Dust Mite.
Korean Journal of Dermatology 1984;22(3):286-294
In this study, the authors attempted to investigate distribution of the house dust mites in Korea on a nationwide scale. Mites were isolated and classified from 211 house dust samples which were collected from 7 urban areas and 3 rural areas. The result were as follows: 1) Nineteen species of mites were identified in this study including 4 new species which were not recorded in Korea. 2) The most frequent house dust mites were Pyroglyphid mites. Among then, Derntatophagoides farinae was found to be dominant species in Korea since this species was more widely distributed and more frequently found than D. pteronyssinus, 3) The occurence rates of Dermatophagoides sp. in the urban areas were higher than that in the rural areas, but vice versa in the occurence rates of other mites accidently found in the dust samples.

PURPOSE: The objective of this research is to provide the indoor environment management education program for the asthma patients and their families and then analyze the effectiveness in education preventing allergic asthma. METHODS: A pre-post single group quasi-experimental design was used to provide an education program about correct indoor environment management to a total of 58 households (29 patient households and 29 normal households). The performance rate of correct indoor environment management procedure, amount of house dust mite antigen, allergy subjective symptoms score and knowledge score about indoor environment management were compared before and after the education to test the effectiveness of the education. RESULTS: Home-visit education in this research had effects in improving subject households' performance rate of indoor environment management procedures, reducing the amount of house dust mite antigen - an important inducing factor of allergy, and reducing perceived subjective symptoms of allergy.

7.The role of specific IgE in allergic rhinitis by house dust mite
Journal of Practical Medicine 2003;445(3):12-14
Studied group includes 42 patients with allergic rhinitis in whole the year by house dust mite. Control group includes 14 healthy, no allergic subjects. In normal person serum specific IgE level was nearly none. The most of allergic rhinitis patients had serum IgE with variois levels. The assay gave the same sensivity and specificity of 85.71%. In 6 patients non-consistent result of the assays was 14.29%. There is a correlation of these 2 assays with a coefficient of r = 6.12

This study was conducted to investigate distribution of the house dust mites in the bedroom of allergic rhinitis patients in Pusan. From July to December 1995, 51 dust samples were drawn from the bedroom of the patients by using electronic vaccum cleaner. House dust mites were isolated from 50mg dust by applying the modified wet sieving method. The results were as follows: 1 Out of a total 49 dust samples(96.1%) were isolated house mites. 2 Total 977 mites were collected and identified the most prevalent house mites was Pyroglypidae mite with 92.2%. Among them D.pteronyssinus was predominant species. 3 In 1gm of the house dust, 100-499 mites were found in 17 samples(33.3%), more then 500 mites in 12 samples (23.6%). 4 The density of Pyoglypidae mite was close associated with the month. 5 The density of house dust mite was not affected by the type of house, region and the relative humidity of the bed room

BACKGROUND AND OBJECTIVE: House dust mites have been known as the most important allergens in respiratory allergic disease. Since environmental factors may have influences on the pathogenesis of allergic disease, the study using Korean house dust mites for immune and biologic reactions in house dust mite-sensitive allergic disease is considered as significant. MATERIAL AND METHOD: We made two in-house allergenic extracts of Korean house dust mites (D. farinae and D. pteronpsssinus) and performed this study for the allergen standardization by in vivo methods and for the evaluation of the reliabilities for clinical applications. RESULT: As a results of biologic standardization using skin prick test teachnique, the activity of 1: 1,500w/v of D. farinae extract was estimated 1,000 biology unit(BU), concentration that elicits a wheal of the same size as that of histamine dihydrochloride 1mg/ml. The activity of 1: 1,000w/v of D. pteronyssinus was condiered as 1,000BU. The activity of 1:100w/v of both D. farinae and D. pteronpssiuns extracts were considered as 100,000 Allergy Unit(AU), based on intradermal skin testing of 30 subjects with strong sensitive reaction. The concordant rates between results of skin prick test done with 5,000BU/ml concentration of in-house allergenic extracts and thoae with the commercially available allergen(Bencard Co., UK) were 84.6% and 81.0% for D. farinae and D. pteronpssinus, respectively. The wheal erythema size and A/H ratios induced by in-house extracts were significantly correlated with those induced by Bencard allergen. CONCLUSION: This results suggest that in-house extracts of the whole bodies of two house dust mites have good allergenic activities in vivo. It is considered to be clinically useful and reliable allergenic extracts.

BACKGROUND: The skin prick test and in vitro allergen-specific IgE assays are commonly used to diagnose atopic diseases. However, there is still a need for comparison of their diagnostic efficiency. Objective and METHOD: To evaluate their clinical efficiency, the results of UniCAP and multiple antigen simultaneous test (MAST) were compared with skin prick test results. After 51 allergic patients completed skin prick test (SPT), serum sample was collected and UniCAP and MAST were performed to determine specific IgE to house dust mite (Dermatophagoides pteronyssinus : Dp and D. farinae. Df). Result : When SPT was used as a reference standard, UniCAP depicted higher sensitivity of 88.8% to Dp IgE and 91.4% to Df - IgE, but lower specificity of 73.3% to Dp IgE and 75.0% to Df - IgE. However, MAST had lower sensitivity of 75.1% to Dp-IgE and 71.4% to Df - IgE, higher specificity of 93.3% to Dp-IgE and 93.7% to Df - IgE. The values of UniCAP and MAST were significantly correlated with the reactivity grade of skin prick test, respectively. Additionally, the response of SPT was not apparently associated with ECP levels. CONCLUSION: These study results may suggest that both UniCAP and MAST are generally feasible for measuring house dust mite - specific IgE and that they are both replicable.
