Objectives The purpose of this study is to establish relationship between allergic diseases and functional gastrointestinal disorders in children and adolescents using objective criteria and questionnaires. Methods This study surveyed 237 children and adolescents who visited the department of Pediatrics of ${\bigcirc}{\bigcirc}$ Korean Medicine Hospital from September 23rd, 2013 to December 26th, 2013. The Korean version of International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and the Korean-translated Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III (QPGS-Rome III) were used. We analyzed the data by using PASW Statistics 18.0 with Chi-square test, Fisher's exact test and Linear by linear association. Results There was no significant difference between prevalence of allergic diseases and functional gastrointestinal disorders. Also, there was no strong relationship between the number of allergic diseases and the functional gastrointestinal disorders. However, some parts showed significant relationships - such as asthma symptoms ever and belch; asthma symptoms last 12 months and belch; allergic rhinitis diagnosis ever and belly aches and abdominal pain around and below the belly button; allergic rhinitis treatment last 12 months and belly aches and abdominal pain around and below the belly button; and atopic dermatitis diagnosis ever and irritable bowel syndrome (respectively; p=0.046, p=0.008, p=0.004, p=0.029, p=0.035). And as the number of allergic diseases increases, the prevalence of functional gastrointestinal disorders are 19.4%, 31.3%, 41.7%, 31.0% respectively. Conclusions Although there was no significant relationship between allergic diseases and functional gastrointestinal disorders, some gastrointestinal symptoms were related to allergic diseases.

Purpose: The purpose of this study was to investigate the factors associated with atopic dermatitis in Korean adults. Methods: The data were obtained from the Korean National Health and Nutrition Survey on 2008. Subjects of this study were 7,280 adults aged older than 18 years. The data were analyzed for demographic characteristics, health status, alcohol drinking, smoking, hypertension, hyperlipidemia, asthma, chronic sinusitis, rhinitis, stress, depression, and suicidal ideation between atopy group and non-atopy group. Results: Among 7,280 subjects, 2.9% of Korean adults had a diagnosis of atopic dermatitis from doctor. Multiple logistic regression identified that the presence of atopic dermatitis was associated with marital status (OR=2.66, CI 1.84~3.86, p<.001), rhinitis (OR=1.52, CI 1.04~2.22, p = .030), and depression (OR=1.89, CI 1.04~3.41, p = .036). Conclusion: Based on these results, marital status, rhinitis, and depression should be considered in addressing individuals with atopic dermatitis. And the other factors contributing to atopic dermatitis need to be specifically identified.

Allergy skin prick test and intradermal test represent one of the major tools in the diagnosis of IgE-mediated diseases like as atopic asthma, allergic rhinitis, atopic dermatitis, food and drug allergy, and insect bite when properly performed. Skin tests are of particular importance in fields such as allergen standardization, pharmacology, and epidemiology. Even if skin tests seem easy to perform, adequate and proper interpretation requires well-trained physicians who can recognize the numerous factors that may modify the results of skin tests.

Objectives: This study investigated the association between air pollutant levels and medical usage rates for environmental disease in a general residential area during the period 2015-2017. Methods: Air pollutant (PM₁₀, PM_2.5, SO₂, NO₂, CO, O₃) data were collected from Air-Korea. Medical usage data on environmental disease (asthma, allergic rhinitis, atopic dermatitis) for the period 2015-2017 in a general residential area in Gyeongsangnam-do Province were provided by the National Health Insurance Corporation. Pearson correlation analysis and multiple regression analysis were conducted to investigate the association between air pollutant levels and medical usage rates (SAS 9.4). In the multiple regression analysis, environmental disease was set as the dependent variable and air pollutants were set as independent variables and analyzed using the General Linear Model. Results: Except for PM_2.5, the average concentration of air pollutants in the surveyed area was below than the air environment standards of Korea. NO₂ was higher than Korea's national average, but CO was similar. The others were lower than the Korea's national average. The daily medical usage rates for environmental disease were 1.38‰ for asthma, 9.90‰ for allergic rhinitis, and 0.32‰ for atopic dermatitis. As a result of correlation analysis, PM₁₀ and SO₂, NO₂ and CO were significantly correlated with asthma, PM₁₀ and NO₂ and CO were correlated with allergic rhinitis, and PM₁₀ and PM_2.5, SO₂, NO₂ and CO were correlated with atopic dermatitis. As a result of multiple regression analysis, PM₁₀ and SO₂ were found to have a higher effect on asthma, PM₁₀ and NO₂ on allergic rhinitis, and SO₂ and NO₂ on atopic dermatitis, compared to other air pollutants. Conclusion: According to these results, air pollutants such as PM₁₀ and SO₂ and NO₂ were associated with the medical usage rates of environmental disease even in relatively low concentrations. Therefore, continuous monitoring will be required for general residential areas.

Atopy is a highly prevalent and serious health problem. The prevalence and severity of asthma and allergic diseases have increased over recent decades, particularly in industrialized nations. Early life infections may protect against the development of atopy and allergic diseases like asthma. The inverse relationship between the incidence of atopy and childhood infections has led to the 'hygiene hypothesis', which suggests that diminished exposure to childhood infections in modern society has led to decreased Th1-type responses. Th1 and Th2 responses are counter-regulatory. Reduced Th1 may lead to enhanced Th2-type inflammation, which is important in promoting asthma and allergic disease via up-regulation of IL-4, IL-5, and IL-13. It is now widely accepted that altered regulation of Th2 responses(and possibly the balance between Th1 and Th2 responses) is an important factor in the development of atopy. CpG DNA represent a novel class of drugs with substantial immunomodulatory properties. CpG DNA contain unmethylated motifs centered on the CpG dinucleotides, like bacterial DNA. These CpG DNA promote Th1 and regulatory type immune responses and suppress Th2 responses. In murine studies, CpG DNA are effective in prevention and treatment of asthma and allergic diseases. CpG DNA are just beginning to be tested in human asthma. While its precise mechanisms continue to be fully studied, CpG DNA offers considerable promise as a novel treatment for atopic inflammation. It may prove to be an important disease modifying therapy, or even curative therapeutic agent for asthma and allergic diseases.

Sphingosine-1-phosphate (S1P) and its receptors have been implicated in atopic dermatitis. S1P₂ was found to function as a proallergic receptor, while its antagonist JTE-013 was found to suppress allergic asthma in mice. Topical application of JTE-013 has not been investigated in an in vivo model of atopic dermatitis. Therefore, the therapeutic potential of JTE-013 topical application was evaluated by the use of a 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis mouse model. DNCB-induced inflammation and mast cell accumulation in skin tissues were significantly suppressed by topical JTE-013 treatment in BALB/c mice. DNCB-induced increase of lymph nodes sizes and elevated inflammatory cytokines (IL-4, IL-13, IL-17, and IFN-γ) in lymph nodes were also significantly reduced by the JTE-013 treatment. Elevated serum levels of IgE were significantly suppressed by the topical treatment of JTE-013. In summary, the topical treatment of JTE-013 S1P₂ antagonist suppressed DNCB-induced atopic dermatitis symptoms and immune responses. These results suggested JTE-013 as a potential therapeutic agent for atopic dermatitis.

목 적 : 아토피성 천식과 비아토피성 천식은 서로 다른 임상양상을 나타내지만 기도 과민성과 기도 염증은 이들 천식의 특징적 소견이다. 본 연구에서는 아토피성 천식과 비아토피성 천식에서 직접 기관지 유발 검사인 메타콜린에 대한 반응과 간접 기관지 유발 검사인 아데노신에 대한 반응의 차이가 있는지, 그리고 이들 기관지 유발 검사와 혈중 호산구 염증 지표들의 연관성에 대해 알아보고자 하였다. 방 법 : 본 연구는 경증 천식 및 중등도 천식으로 진단받은 환아 116명을 대상으로 하였으며 이중 아토피성 천식군이 82명, 비아토피성 천식군이 34명이었다. 환아들은 혈중 호산구 수와혈청 eosinophil cationic protein(ECP) 농도를 측정하였고 메타콜린과 아데노신 기관지 유발 검사를 시행하였다. 기관지 유발검사에 대한 반응은 메타콜린 $PC_{20}$와 아데노신 $PC_{20}$로 나타내었고 기도 과민성의 판정 기준은 각각 메타콜린 $PC_{20}$이 16 mg/mL 미만인 경우와 아데노신 $PC_{20}$이 200 mg/mL 미만인 경우로 하였다. 결 과 : 아토피성 천식군에서 각각 95.1%와 90.2%가 메타콜린 기관지 유발 검사와 아데노신 기관지 유발 검사에 양성을 보였고 비아토피성 천식군에서는 각각 94.1%와 52.9%가 메타콜린과 아데노신 기관지 유발 검사에 양성을 나타내었다. 아토피성 천식군과 비아토피성 천식군에서 아데노신 $PC_{20}$의 기하평균은 31.6 mg/mL과 125.6 mg/mL로 아토피성 천식군에서 더 낮은 값을 보였고 메타콜린 $PC_{20}$의 기하평균은 차이가 없었다. 기도과민성과 혈중 호산구 염증 지표들과의 관련성은 아데노신 기도과민성의 경우 아토피성 천식군에서는 혈청 ECP 농도와 r=-0.23, P<0.01, 혈중 호산구 수와는 r=-0.30, P<0.01로 연관성이 있었고 비아토피성 천식군에서는 혈청 ECP 농도와는 연관성이 없었으나 혈중 호산구 수와는 r=-0.57, P<0.01로 유의한 상관관계를 보였다. 그러나 메타콜린 기도 과민성의 경우 두 군 모두에서 혈중 호산구 염증 지표들과 연관성이 없었다. 결 론 : 아토피성 천식 환아들은 비아토피성 천식 환아들에 비해 더 심한 아데노신 기도 과민성을 보였다. 또한, 아토피성 천식 환아들에서 아데노신 기도 과민성은 혈중 호산구 수 뿐만 아니라 혈청 ECP 농도와도 연관성을 보였다. 그러나 비아토피성 천식 환아들은 혈중 호산구 수와만 상관관계를 보였다. 따라서 아데노신 기도 과민성은 천식의 기도 염증을 반영하나 비아토피성 천식의 기도 염증보다는 아토피성 천식에서의 기도 염증을 더 잘 반영하는 것으로 생각된다.

The myosin light chain kinase (MYLK) gene encodes both smooth muscle and nonmuscle cell isoforms. Recently, polymorphisms in MYLK have been reported to be associated with several diseases. To examine the genetic effects of polymorphisms on the risk of asthma and related phenotypes, we scrutinized MYLK by re-sequencing/genotyping and statistical analysis in Korean population (n = 1,015). Seventeen common polymorphisms located in or near exons, having pairwise $r^2$ values less than 0.25, were genotyped. Our statistical analysis did not replicate the associations with the risk of asthma and log-transformed total IgE levels observed among African descendant populations. However, two SNPs in intron 16 (+89872C> G and +92263T> C), which were in tight LD (|D'| = 0.99), revealed significant association with log-transformed blood eosinophil level even after correction multiple testing ($P=0.002/P^{corr}=0.01$ and $P=0.002/P^{corr}=0.01$, respectively). The log-transformed blood eosinophil levels were higher in individuals bearing the minor alleles for +89872C> G and +92263T> C than in those bearing other allele. In additional subgroup analysis, the genetic effects of both SNPs were much more apparent among asthmatic patients and atopic asthma patients. Among atopic asthma patients, the log-transformed blood eosinophil levels were proportionally increased by gene-dose dependent manner of in both +89872C> G and +92263T> C(P = 0.0002 and P = 0.00007, respectively). These findings suggest that MYLK polymorphisms might be among the genetic factors underlying differential increases of blood eosinophil levels among asthmatic patients. Further biological and/or functional studies are needed to confirm our results.
