J Allergy Clin Immunol 2024; 153:1604-1610.e2. [PMID: 38438085 DOI: 10.1016/j.jaci.2024.02.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 01/08/2024] [Accepted: 02/12/2024] [Indexed: 03/06/2024]
Abstract
BACKGROUND The atopic march refers to the coexpression and progression of atopic diseases in childhood, often beginning with atopic dermatitis (AD), although children may not progress through each atopic disease. OBJECTIVE We hypothesized that future atopic disease expression is modified by AD phenotype and that these differences result from underlying dysregulation of cytokine signaling. METHODS Children (n = 285) were enrolled into the Childhood Origins of Asthma (COAST) birth cohort and followed prospectively. Rates of AD, food allergy, allergic rhinitis, and asthma were assessed longitudinally from birth to 18 years of age. Associations between AD phenotype and food allergy, allergic rhinitis, asthma, allergic sensitization, exhaled nitric oxide, and lung function were determined. Peripheral blood mononuclear cell responses (IL-5, IL-10, IL-13, IFN-γ) to dust mite, phytohemagglutinin, Staphylococcus aureus Cowan I, and tetanus toxoid were compared among AD phenotypes. RESULTS AD at year 1 was associated with an increased risk of food allergy (P = .004). Both persistent and late-onset AD were associated with an increased risk of asthma (P < .001), rhinitis (P < .001), elevated total IgE (P < .001), percentage of aeroallergens with detectable IgE (P < .001), and elevated exhaled nitric oxide (P = .002). Longitudinal analyses did not reveal consistent differences in peripheral blood mononuclear cell responses among dermatitis phenotypes. CONCLUSION AD phenotype is associated with differential expression of other atopic diseases. Our findings suggest that peripheral blood cytokine dysregulation is not a mechanism underlying this process, and immune dysregulation may be mediated at mucosal surfaces or in secondary lymphoid organs.

Abstract
The common respiratory abnormality, small airway dysfunction (fSAD), is easily neglected. Its prognostic factors, prevalence, and risk factors are unclear. This study aimed to explore the early detection of fSAD using radiomic analysis of computed tomography (CT) images to predict fSAD progress. The patients were divided into fSAD and non-fSAD groups and divided randomly into a training group (n = 190) and a validation group (n = 82) at a 7:3 ratio. Lung kit software was used for automatic delineation of regions of interest (ROI) on chest CT images. The most valuable imaging features were selected and a radiomic score was established for risk assessment. Multivariate logistic regression analysis showed that age, radiomic score, smoking, and history of asthma were significant predictors of fSAD (P < 0.05). Results suggested that the radiomic nomogram model provides clinicians with useful data and could represent a reliable reference to form fSAD clinical treatment strategies.

Abstract
OBJECTIVE To evaluate the prevalence and distribution of sensitization to aeroallergens in children with atopic diseases. METHODS We conducted skin prick test on 9,527 pediatric patients (aged 0-17 years) with atopic diseases in allergy department of Children's Hospital affiliated with the Capital Institute of Pediatrics. Positive rates of aeroallergens were compared among the different groups. RESULTS Boys (69.5%) had a higher positive rate in SPT results than girls (59.8%; χ2 = 91.7, P < 0.01), and the prevalence of sensitization to aeroallergens increased from 56.1% in the 0-5 year group, to 73.0% in patients above 12 years. Japanese hop (36.2%) and D. farinae (28.1%) were the most common outdoor and indoor aeroallergens, respectively. From low to high age groups, the positive detection rates of D. farinae were 20.3, 30.6, and 33.5%, respectively, followed by D. pteronyssinus (15.7, 24.8, and 30.0%) and cat dander (8.6, 19.8, and 27.9%, respectively), while dog dander and cockroach showed the same trend. The top three positive detection rates of outdoor aeroallergens were Alternaria (30.9%), Japanese Hop (26.7%), and Artemisia (23.7%) in the preschool age group. With regard to patients aged 6 to 11 years, the three most common were Japanese hop (39.2%), Alternaria (36.4%), and Fraxinus pollen (34.4%). Japanese hop (43.8%), Sabina (41.1%), and birch pollen (39.6%) became increasingly common allergens among adolescents. There were more patients with strongly positive reactions to Alternaria in AS (χ2 = 10.2, P < 0.01) and AS with AR groups (χ2 =9.7, P < 0.01) than those in the AR group. Asthmatic patients had significantly higher multiple positive reactions than those with AR (P < 0.01). Asthmatic patients had a much higher prevalence of HDM, animal dander, and Alternaria than those with allergic rhinitis (P < 0.05). CONCLUSION The prevalence of sensitization to aeroallergens increased with age in children with atopic diseases in Greater Beijing Region. Alternaria was the predominant allergen before 5 years of age, and tree pollen had delayed sensitization in adolescents. Sensitization to perennial allergens such as HDM, cats, and Alternaria was more strongly associated with asthma risk. Sensitization to more than one allergen significantly affected asthmatic patients.

Abstract
BACKGROUND Asthma is one of the most common chronic diseases in the world, with ∼100 million asthma patients worldwide. China has become one of the countries with the highest asthma death rate in the world. Asthma is a chronic airway inflammatory disease. Patients with this disease may have symptoms such as cough, wheezing, and difficulty breathing. For many years, Western medicine has mainly used anti-inflammatory, anti-bronchial spasm, asthma, cough, and oxygen to treat this disease, but the effect is not good. Tuina is a common treatment for asthma in China. But at present, there is no systematic evaluation report on its therapeutic effectiveness and safety. This protocol aims to reveal the efficacy and safety of Tuina for treating asthma. METHODS The following databases will be searched by electronic methods: PubMed, EBASE, WHO International Clinical Trials Registry Platform, Embase, the Chinese Biomedical Literature Database (CBM), Wan-fang Data (WANFANG), the China National Knowledge Infrastructure (CNKI), and other sources from inception to November 2020. Bias risk, subgroup analysis, data synthesis, and meta-analyses will be assessed with RevMan V.5.3 software if the data is met inclusion conditions. RESULTS This study will present a quality evidence of Tuina for the treatment of astma patients. CONCLUSION The systematic review will present reliable evidence to judge whether or not Tuina is a safe and effective intervention for asthma patients.

Abstract
BACKGROUND Few data exist on the predictors of asthma remission by early adulthood in North America. OBJECTIVE The predictors of adult asthma remission were determined in a multiethnic population of patients with mild-to-moderate persistent childhood asthma. METHODS Asthma remission in early adulthood was measured by using 2 definitions: a clinical and a strict definition. Both included normal lung function and the absence of symptoms, exacerbations, and medication use. The strict definition also included normal airways responsiveness. Predictors were identified from 23 baseline measures by using multivariate logistic regression. The probability of remission was modeled by using decision tree analysis. RESULTS In 879 subjects the mean ± SD baseline age was 8.8 ± 2.1 years, 59.4% were male, and 68.7% were white. By adulthood, 229 (26.0%) of 879 participants were in clinical remission, and 111 (15.0%) of 741 participants were in strict remission. The degree of FEV1/forced vital capacity (FVC) ratio impairment was the largest predictor of asthma remission. More than half of boys and two thirds of girls with baseline FEV1/FVC ratios of 90% or greater were in remission at adulthood. Decreased airways responsiveness was also a predictor for both remission definitions (clinical remission odds ratio, 1.23 [95% CI, 1.09-1.39]; strict remission odds ratio, 1.52 [95% CI, 1.26-1.84]). The combination of normal FEV1/FVC ratio, airways responsiveness, and serum eosinophil count at baseline yielded greater than 80% probability of remission by adulthood. CONCLUSION A considerable minority of patients with persistent childhood asthma will have disease remission by adulthood. Clinical prognostic indicators of asthma remission, including baseline lung function, can be seen from an early age.
