In allergic mice, declining lung acetate levels correlated with increased HDM-specific IgE in serum and IL-13 release by ex vivo HDM-restimulated lung cells.

The independent association between sensitization and lung function is unclear.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Objectives</h3>\u0000 \u0000 <p>To examine factors associated with lung function in adolescence, with special interests in sensitization and asthma.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>All schoolchildren in grade one and two (median age 8) in two municipalities in Northern Sweden were invited to a questionnaire survey of allergic diseases and skin prick tests to aeroallergens. This was repeated at ages 12 and, at 19 years also including spirometry and <i>n</i> = 1495 participated at all three occasions. Associations between risk factors and FEV₁, FVC and FEV₁/FVC were analysed by linear regression.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Aeroallergen sensitization was not associated with lung function, irrespective of age at onset, type or degree of sensitization. Early-onset asthma, both persistent (B −0.35, 95% CI –0.60 to −0.09) and in remission (B −0.43, 95% CI –0.74 to −0.12) was associated with lower FEV₁. Persistent asthma was associated with lower FEV₁/FVC (B −0.81, 95% CI –1.07 to −0.55), and remission with lower FVC (B −0.37, 95% CI –0.67 to −0.70). No interaction between asthma and sensitization was found. Maternal smoking in pregnancy was associated with lower FEV₁/FVC. Underweight at age 19 years was associated with lower FEV₁ and FVC and overweight was associated with higher FEV₁ and FVC, but lower FEV₁/FVC.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Aeroallergen sensitization was not independently associated with lung function. Early onset asthma was strongly associated with lung function impairments in young adulthood and in sensitized and non-sensitized individuals alike.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10334,"journal":{"name":"Clinical and Translational Allergy","volume":"15 7","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clt2.70084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687849","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}
