Background: Biologics can induce remission in some patients with severe asthma, however, little is known about pre-biologic disease trajectories and their association with outcomes from biological treatment. We aimed to identify long-term trajectories of disease progression in patients initiating biologics and investigate trajectory associations with disease burden and impact on biologic therapy efficacy.
Methods: Patients in the Danish Severe Asthma Registry initiating biologic therapy between 2016-2022 were included and followed retrospectively in prescription databases starting 1995.
Background And Aim: Asthma in early life has been linked to subsequent development of COPD and according to GOLD 2023 COPD may be divided into distinct subtypes. We aimed to investigate factors associated with the GOLD classification COPD-A (asthma in childhood) and COPD-C (tobacco exposure) in a cohort of adults with a history of severe childhood asthma.
Patients And Methods: In a cohort of Danish adults with a history of severe childhood asthma and a previous 4-month stay during childhood at the asthma care facility in Kongsberg, Norway, we divided participants in a long-term follow-up examination into COPD-A and COPD-C, defined as post-bronchodilator FEV/FVC < 0.
Background: In patients with severe asthma, treatment with anti-interleukin-5 (IL-5) biologics can lead to a reduction in fractional exhaled nitric oxide (FeNO) in some patients. The clinical implications of varying FeNO responses to anti-IL-5 biologics remain unclear. This study aims to categorise patients based on their FeNO response to anti-IL-5 biologics and evaluate the association of these categories with clinical outcomes.

DB-related symptoms can be measured with the 25-item Self Evaluation of Breathing Questionnaire (SEBQ). However, the SEBQ is not available in Danish.
View Article and Find Full Text PDFBackground And Objective: Our knowledge of socioeconomic status (SES) and emergency department (ED) visits in adults with a history of severe childhood asthma is limited. Our aim was, therefore, to investigate these variables in individuals with a history of severe childhood asthma compared to a control population.
Methods: The Kongsberg cohort comprises Danish individuals with a history of severe childhood asthma and a previous 4-month stay at an asthma care facility in Kongsberg, Norway, between 1950 and 1979.

Background: Phenotype classification contributes to risk assessment of asthma. Previous studies have applied this concept primarily to adult populations and in the setting of research protocol assessments which may not be applicable to clinical settings.
Objective: Exploring the value of routinely collected clinical data for phenotype classification and risk assessment of childhood asthma.
Background: Childhood asthma is a prevalent condition with potential impacts on adult life.
Research Question: In a 60-year follow-up study of adults with a history of severe childhood asthma, what are the potential differences in characteristics between individuals with persistent asthma and asthma remission in adulthood?
Study Design And Methods: Danish adults with a history of childhood asthma and a 4-month stay at an asthma care facility in Kongsberg, Norway (1950-1979) in childhood were included. Recruitment was carried out through social media and personal invitation letters.
Background: Biologic asthma therapies reduce exacerbations and long-term oral corticosteroids (LTOCS) use in randomized controlled trials (RCTs); however, there are limited data on outcomes among patients ineligible for RCTs. Hence, we investigated responsiveness to biologics in a real-world population of adults with severe asthma.
Methods: Adults in the International Severe Asthma Registry (ISAR) with ≥24 weeks of follow-up were grouped into those who did, or did not, initiate biologics (anti-IgE, anti-IL5/IL5R, anti-IL4/13).

Background: The effect of dual systemic antibiotic therapy against Pseudomonas aeruginosa in patients with pre-existing lung disease is unknown. To assess whether dual systemic antibiotics against P. aeruginosa in outpatients with COPD, non-cystic fibrosis (non-CF) bronchiectasis, or asthma can improve outcomes.
View Article and Find Full Text PDFRationale: It is unclear how each individual asthma symptom is associated with asthma diagnosis or control.
Objectives: To assess the performance of individual asthma symptoms in the identification of patients with asthma and their association with asthma control.
Methods: In this cross-sectional study, we assessed real-world data using the MASK-air app.
Objectives: Inhaled corticosteroids (ICS) are widely used in patients with chronic obstructive pulmonary disease (COPD). However, ICS are associated with an increased risk of adverse effects.We aimed to determine whether an association between a lower respiratory tract culture with and increasing ICS dosing in patients with COPD exists.
View Article and Find Full Text PDFBackground: Chronic obstructive pulmonary disease (COPD) is a common disease associated with premature death. Tobacco exposure is the main risk factor, but lower socioeconomic status, early life insults, and occupational exposures are also important risk factors. Socially marginalized people, facing homelessness, substance use disorder, and mental illness, are likely to have a higher risk of developing COPD, and, furthermore, experience barriers to healthcare access and consequently poorer outcomes.
View Article and Find Full Text PDFBackground: Asthma is the most common chronic illness in children, carrying a major burden. Socioeconomic position (SEP) affects adult asthma outcomes, but its impact on childhood asthma, particularly in primary versus specialist care, has not been studied thoroughly.
Methods: In a Danish cohort consisting of all children aged 2-17 years redeeming inhaled corticosteroids in 2015, parental SEP impact on asthma outcomes was investigated.
Background: There is little agreement on clinically useful criteria for identifying real-world responders to biologic treatments for asthma.
Objective: To investigate the impact of pre-biologic impairment on meeting domain-specific biologic responder definitions in adults with severe asthma.
Methods: This was a longitudinal, cohort study across 22 countries participating in the International Severe Asthma Registry (https://isaregistries.
Background: Early recognition of cardiac dysfunction in patients with chronic obstructive pulmonary disease (COPD) may prevent future cardiac impairment and improve prognosis. Quantitative assessment of subsegmental and segmental vessel volume by Computed Tomographic (CT) imaging can provide a surrogate of pulmonary vascular remodeling. We aimed to examine the relationship between lung segmental- and subsegmental vessel volume, and echocardiographic measures of cardiac structure and function in patients with COPD.

Our aim was to assess the degree of association between cataract and corticosteroid exposure in patients with asthma and COPD.
Methods: A systematic literature review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

Background: Non-T2 asthma is characterized by the absence of elevated type 2 inflammatory biomarkers such as blood-eosinophils, total and allergen-specific Immunoglobulin E and Fractional exhaled Nitric Oxide (FeNO). According to guidelines, inhaled corticosteroids (ICS) are the cornerstone of asthma management. However, ICS treatment is associated with a risk of local side effects, including hoarseness and thrush, and long-term high-dose therapy may cause systemic adverse effects.

The purpose of this study is to investigate the long-term prognosis of severe childhood asthma in search for an association between asthma in early life and obstructive lung disease in adulthood.
Methods: This study is based on the Kongsberg cohort, which includes approximately 5000 children with severe asthma with a 4-month stay at the asthma care facility in Kongsberg, Norway during the years 1950 to 1979.

Objectives: The clinical significance of Stenotrophomonas maltophilia in patients with COPD is poorly understood. We aimed to determine whether a lower respiratory tract culture positive for S. maltophilia in COPD patients was independently associated with increased risk of death and hospitalisation for exacerbation of COPD.
