The left lingular division was the most frequently involved lung lobe (20.4%). There were no significant differences in the demographics (age, sex, body mass index, smoking history, and comorbidities) or ACT results between the 2 groups. The bronchiectasis group used inhaled corticosteroids/long-acting β2-agonists (<i>P</i> = 0.074) and mucolytics (<i>P</i> < 0.001) more frequently than the control group. Compared to the control group, the bronchiectasis group had lower forced expiratory volume in 1 second (FEV1) (L) (1.9 ± 0.7 L vs. 2.3 ± 0.9 L, <i>P</i> = 0.039) and FEV1%predicted (67.2 ± 22.2%predicted vs. 77.1 ± 20.0%predicted, <i>P</i> = 0.038). The rate of hospital admission to a general ward in the preceding year was significantly higher in the bronchiectasis group compared to those of the control group (23.8% vs. 3.5%, <i>P</i> = 0.005) with an adjusted odds ratio of 6.308 (95% confidence interval, 1.401-28.392). Patients with non-severe asthma and bronchiectasis had lower lung function and more frequent exacerbations requiring hospitalization than those without bronchiectasis. More attention is needed for asthmatic patients with bronchiectasis, even if the asthma is not severe.</p>","PeriodicalId":7547,"journal":{"name":"Allergy, Asthma & Immunology Research","volume":"16 3","pages":"291-299"},"PeriodicalIF":4.1,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11199153/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141441988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this nationwide population-based study, we aimed to analyze the prevalence of severe AD and chronic systemic diseases in Koreans aged ≤ 20 years between 2011 and 2019 using the data from the Korean Health Insurance Review and Assessment Service. Total AD and severe AD were defined according to the International Classification of Diseases-10 code L20. In children aged 6-20 years, the prevalence of severe AD significantly increased from 0.02% in 2011 to 0.04% in 2019 (<i>P</i> for trend < 0.001), with the ratio of severe AD to total AD increasing from 0.76% in 2011 to 1.10% in 2019 (<i>P</i> for trend < 0.001). The prevalence rates of severe AD significantly increased between 2011 and 2019 in children aged 6-12 years (<i>P</i> for trend < 0.05) and 13-18 years (<i>P</i> for trend < 0.001). Severe AD was more frequently found in males than in females each year (all <i>P</i> < 0.001, from 2011 to 2019). During the period from 2011 to 2019, the prevalence rate of chronic systemic diseases was higher in subjects with severe AD than in those without AD (<i>P</i> < 0.001) or with mild-to-moderate AD (<i>P</i> < 0.001). In conclusion, our results suggest that the prevalence of severe AD is increasing in Korean children and adolescents and is higher in males and older age groups. Moreover, severe AD is associated with chronic systemic diseases. Therefore, more attention should be paid to managing severe AD.</p>","PeriodicalId":7547,"journal":{"name":"Allergy, Asthma & Immunology Research","volume":"16 3","pages":"300-307"},"PeriodicalIF":4.1,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11199157/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141441984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
