Incidence and predictors of asthma exacerbations in middle-aged and older adults: the Rotterdam Study. ERJ Open Res 2021; 7:00126-2021. [PMID: 34262968 PMCID: PMC8273296 DOI: 10.1183/23120541.00126-2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 04/09/2021] [Indexed: 11/05/2022] Open
Abstract
Aim The aim of this study was to investigate occurrence and determinants of asthma exacerbations in an ageing general population. Methods Subjects aged 45 years or above with physician-diagnosed asthma in the Rotterdam Study, a population-based prospective cohort from January 1991 to May 2018, were assessed for asthma exacerbations. Exacerbations were defined as acute episodes of worsening asthma treated with oral corticosteroids. Cox proportional hazards analysis was used to investigate risk factors for a future exacerbation. Results Out of 763 participants with asthma (mean age 61.3 years, 69.2% female), 427 (56.0%) experienced at least one exacerbation, in a mean follow-up time of 13.9 years. The mean annual exacerbation rate was 0.22. Most exacerbations occurred during winter months. Risk factors for exacerbations were a history of previous exacerbations (HR 4.25; 95% CI 3.07–5.90, p<0.001)), respiratory complaints (HR 2.18; 95% CI 1.48–3.21, p<0.001), airflow obstruction (HR 1.52; 95% CI 1.07–2.15, p=0.019), obesity (HR 1.38; 95% CI 1.01–1.87, p=0.040) and depressive symptoms (HR 1.55; 95% CI 1.05–2.29, p=0.027). Compared to those not using respiratory medication, we observed higher hazard ratios for those on short-acting β2-agonists (SABA, i.e. rescue medication) only (HR 3.08, 95% CI 1.61–5.90, p=0.001) than those on controller medication (HR 2.50, 95% CI 1.59–3.92, p<0.001). Conclusion Many older adults with asthma suffer from at least one severe exacerbation. Previous exacerbations, use of SABA without concomitant controller medication, respiratory complaints, obesity, airway obstruction and depression are independent risk factors for exacerbations. Most middle-aged and older adults with asthma suffer from at least one severe exacerbation. Risk factors are previous exacerbations, use of SABA without concomitant controller medication, respiratory complaints, obesity, airway obstruction and depression.https://bit.ly/3gcTO6t

A Systematic Review of Asthma Phenotypes Derived by Data-Driven Methods. Diagnostics (Basel) 2021; 11:diagnostics11040644. [PMID: 33918233 PMCID: PMC8066118 DOI: 10.3390/diagnostics11040644] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 03/30/2021] [Accepted: 03/31/2021] [Indexed: 12/13/2022] Open
Abstract
Classification of asthma phenotypes has a potentially relevant impact on the clinical management of the disease. Methods for statistical classification without a priori assumptions (data-driven approaches) may contribute to developing a better comprehension of trait heterogeneity in disease phenotyping. This study aimed to summarize and characterize asthma phenotypes derived by data-driven methods. We performed a systematic review using three scientific databases, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. We included studies reporting adult asthma phenotypes derived by data-driven methods using easily accessible variables in clinical practice. Two independent reviewers assessed studies. The methodological quality of included primary studies was assessed using the ROBINS-I tool. We retrieved 7446 results and included 68 studies of which 65% (n = 44) used data from specialized centers and 53% (n = 36) evaluated the consistency of phenotypes. The most frequent data-driven method was hierarchical cluster analysis (n = 19). Three major asthma-related domains of easily measurable clinical variables used for phenotyping were identified: personal (n = 49), functional (n = 48) and clinical (n = 47). The identified asthma phenotypes varied according to the sample’s characteristics, variables included in the model, and data availability. Overall, the most frequent phenotypes were related to atopy, gender, and severe disease. This review shows a large variability of asthma phenotypes derived from data-driven methods. Further research should include more population-based samples and assess longitudinal consistency of data-driven phenotypes.

ENVIRONMENT INTERNATIONAL 2020; 144:106017. [PMID: 32829252 DOI: 10.1016/j.envint.2020.106017] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 07/26/2020] [Indexed: 06/11/2023]
Abstract
An adverse role of frequent domestic use of cleaning agents, especially in spray form, on asthma has been reported. However, sparse studies have investigated respiratory health effects of chronic domestic exposure to irritant cleaning agents. This study aims to investigate associations between weekly use of irritant domestic cleaning products and current allergic and non-allergic asthma in a large cohort of elderly women. We used data from the Asthma-E3N nested case-control study on asthma (n = 19,404 women, response rate: 91%, 2011), in which participants completed standardized questionnaires on asthma and on the use of domestic cleaning products including irritants (bleach, ammonia, solvents and acids). Allergic multimorbidity in asthma was assessed from allergic-related medications recorded in drug refunds database. The association between use of irritants and current asthma was estimated by logistic regression (current vs. never asthma) and multinomial logistic regression (never asthma, non-allergic asthma, allergic asthma) adjusted on age, smoking status and body mass index (BMI). In the 12,758 women included in the analysis (mean age: 70 years, current smokers: 4%, BMI ≥ 25 kg/m2: 32%, low education: 11%, current asthma: 23%), 47% reported weekly use of at least one irritant cleaning product at home. Weekly use of irritant products was associated with a higher risk of current asthma (adjusted Odds-Ratio: 1.17, 1.07-1.27). A statistically significant dose-response association was reported (p trend < 0.0001), with both the number of irritant products used weekly (1 irritant: 1.12, 1.02-1.23; 2 irritants: 1.21, 1.05-1.39; 3 irritants or more: 2.08, 1.57-2.75) and the frequency of use (1-3 days/week: 1.12, 1.02-1.23; 4-7 days/week: 1.41,1.22-1.64). A dose-response association was observed with the frequency of products used (p trend < 0.05), for both non-allergic (4-7 days/week: 1.27, 1.02-1.57) and allergic asthma (1.52, 1.27-1.82). In conclusion, weekly use of common cleaning irritants was associated with an increased risk of current asthma, whatever the allergic status.
