Abstract
The concept of "remission" in asthma has been around for a long time and it has been a controversial topic. Despite the attempts of some studies to characterize this entity, the discussion continues. In the case of asthma there is still no clear definition, either in terms of its meaning or the parameters that should be included or whether it should be divided into clinical or complete remission. To help defining these controversial concepts, SEPAR has advocated the multidisciplinary working group REMAS (REMission in ASthma). Following the Delphi methodology and with the involvement of more than 120 specialists in asthma management, this group has arrived at a consensus on the definitions of remission in asthma and establishing the criteria and characteristics that will be of use in future studies evaluating the efficacy or effectiveness of treatments.

Abstract
INTRODUCTION The relationship between immediate symptom control, reliever medication use and exacerbation risk on treatment response and factors that modify it have not been assessed in an integrated manner. Here we apply simulation scenarios to evaluate the effect of individual baseline characteristics on treatment response in patients with moderate-severe asthma on regular maintenance dosing monotherapy with fluticasone propionate (FP) or combination therapy with fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR). METHODS Reduction in reliever medication use (puffs/24 h), change in symptom control scores (ACQ-5), and annualised exacerbation rate over 12 months were simulated in a cohort of patients with different baseline characteristics (e.g. time since diagnosis, asthma control questionnaire (ACQ-5) symptom score, smoking status, body mass index (BMI) and sex) using drug-disease models derived from large phase III/IV clinical studies. RESULTS Simulation scenarios show that being a smoker, having higher baseline ACQ-5 and BMI, and long asthma history is associated with increased reliever medication use (p < 0.01). This increase correlates with a higher exacerbation risk and higher ACQ-5 scores over the course of treatment, irrespective of the underlying maintenance therapy. Switching non-responders to ICS monotherapy to combination therapy after 3 months resulted in immediate reduction in reliever medication use (i.e. 1.3 vs. 1.0 puffs/24 h for FP/SAL and BUD/FOR, respectively). In addition, switching patients with ACQ-5 > 1.5 at baseline to FP/SAL resulted in 34% less exacerbations than those receiving regular dosing BUD/FOR (p < 0.01). CONCLUSIONS We have identified baseline characteristics of patients with moderate to severe asthma that are associated with greater reliever medication use, poor symptom control and higher exacerbation risk. Moreover, the effects of different inhaled corticosteroid (ICS)/long-acting beta agonist (LABA) combinations vary significantly when considering long-term treatment performance. These factors should be considered in clinical practice as a basis for personalised management of patients with moderate-severe asthma symptoms.

Abstract
BACKGROUND Childhood asthma is a prevalent condition with potential impact 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 in 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. Participants completed questionnaires and underwent spirometry, bronchial provocation, and bronchodilator reversibility and blood tests. Asthma remission was defined as no use of asthma medication and no asthma symptoms within the past 12 months, with the remaining participants being classified as having current asthma. RESULTS Among 1,394 eligible participants, 232 participants completed the follow-up. Ninety percent had current asthma, of whom 26% reported exacerbations in the past year. Only 16% of all the participants were managed in secondary care. Common comorbidities were allergic rhinitis (60%), hypertension (21%), eczema (16%), and cataract (8%). Compared with participants in remission, participants with persistent asthma showed higher total IgE (P = .03) and both lower FEV1 % predicted (P = .03) and FEV1 to FVC ratio (P < .001), as well as numerically higher fractional exhaled nitric oxide and blood eosinophil count. INTERPRETATION Our 60-year follow-up study of adults with a history of severe childhood asthma revealed that nine of 10 participants still had current asthma. Persistent asthma was associated with lower lung function and higher levels of type 2 inflammatory biomarkers compared with asthma remission.

Abstract
The long-term goal of asthma management is to achieve disease control, comprising the assessment of 2 main domains: (1) symptom control and (2) future risk of adverse outcomes. Decades of progress in asthma management have correlated with increasingly ambitious disease control targets. Moreover, the introduction of precision medicines, such as biologics, has further expanded the limits of what can be achieved in terms of disease control. It is now believed that clinical remission, a term rarely associated with asthma, may be an achievable treatment goal. An expert framework published in 2020 took the first step toward developing a commonly accepted definition of clinical remission in asthma. However, there remains a widespread discussion about the clinical parameters and thresholds that should be included in a standardized definition of clinical remission. This review aims to discuss on-treatment clinical remission as an aspirational outcome in asthma management, drawing on experiences from other chronic diseases where remission has long been a goal. We also highlight the integral role of shared decision-making between patients and health care professionals and the need for a common understanding of the individual patient journey to remission as foundational elements in reducing disease burden and improving outcomes for patients with asthma.

Abstract
PURPOSE OF REVIEW The development of biological therapies for type 2 inflammatory diseases raises the possibility of addressing remission in those dis-immune conditions. No consensus exists for a definition of remission in chronic rhinosinusitis with nasal polyps (CRSwNP). This review aims to critically evaluate the published data to provide the basis for defining remission in CRSwNP. RECENT FINDINGS The published evidence has yet to provide an unequivocal definition on remission in type 2 inflammatory diseases, in part reflecting differences in approaches to diagnosis and follow-up. A multidimensional evaluation is necessary when considering complete remission, including clinical, inflammatory, and histologic criteria, but how to combine or tailor the three perspectives according to disease severity at baseline or timing of assessment of treatment category is yet to reach consensus. We suggest defining remission starting from the approach taken in asthma and eosinophilic esophagitis, that is, including the resolution of symptoms and improvements in objective parameters of disease severity and/or inflammatory activity. Future studies and consensuses should provide validated criteria with cutoffs for the day-to-day definition of remission. The definition of remission in CRSwNP should include the following criteria, to be verified and maintained for a period of ≥ 12 months: absence of symptoms (nasal obstruction, loss of smell, rhinorrhea as the main ones); no impact of symptoms on quality of life; no need of surgery; no chronic or rescue medications (systemic corticosteroids or antibiotics); and recovery of smell function, possibly evaluated by objective test. Assessment of underlying inflammation should also be considered once accurate and feasible biomarkers are available in clinical practice.

Abstract
Objective This study aims to assess the associations of complete blood cell count (CBC)-derived inflammatory biomarkers with the prevalence of asthma and mortality. Methods Data was collected from the 1999-2018 National Health and Nutrition Examination Survey (NHANES). Mortality was identified using the National Death Index until December 31, 2019. The study analyzed the relationship between CBC-derived inflammatory biomarkers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic inflammatory response index (SIRI), and systemic immune-inflammation index (SII), and the prevalence of asthma using multiple logistic regressions. To assess the significance of CBC-derived inflammatory biomarkers in predicting all-cause and respiratory disease mortality in asthma patients, Cox proportional regressions and the random survival forest (RSF) analysis were utilized. Results A total of 48,305 participants were included, with a mean age of 47.27 ± 0.18 years and 49.44% male. Among them, 6,403 participants had asthma, with a prevalence of 13.28%. The all-cause and respiratory disease deaths at a median follow-up of 8.2 (4.5, 12.8) years were 929 and 137 respectively. After adjusting for confounders, the prevalence of asthma was found to be positively associated with NLR, PLR, MLR, SIRI and SII. Compared to the lowest quartile, the highest quartile of NLR (HR=1.765 [1.378-2.262]), MLR (HR=1.717 [1.316-2.241]), SIRI (HR=1.796 [1.353-2.383]) and SII (HR=1.432 [1.141-1.797]) were associated with an increased risk of all-cause mortality. These associations were more pronounced in respiratory disease mortality of asthma patients. RSF analysis showed that MLR had the highest predictive value for all-cause and respiratory disease mortality in adults with asthma. The sensitivity analysis demonstrated the stability of our results. Conclusion The findings suggest that CBC-derived inflammatory biomarkers are associated with a higher risk of all-cause and respiratory disease mortality in adults with asthma.

Abstract
BACKGROUND Although asthma and allergic rhinitis are chronic diseases, some patients experience periods of remission. Information on prognostic factors associated with the remission of asthma and allergic rhinitis is valuable in resource prioritization. This study investigated factors associated with the clinical remission of asthma and allergic rhinitis. METHODS In the Respiratory Health In Northern Europe (RHINE) study, data was collected with questionnaires in stage one (RHINE I, 1989-1992) and two follow-ups (RHINE II, 1999-2001 and RHINE III, 2010-2012) from Sweden, Norway, Denmark, Iceland and Estonia. Clinical remission was defined as having reported asthma or allergic rhinitis in RHINE I or RHINE II but not in RHINE III. RESULTS Of 13,052 participants, 975 (7.5%) reported asthma in RHINE I or RHINE II, and 3379 (25.9%) allergic rhinitis. Clinical remission of asthma and allergic rhinitis was found in 46.4% and 31.8%, respectively. Living in Estonia (OR (95% CI) 2.44 (1.22-4.85)) and living in an apartment (1.45 (1.06-1.98)) were related to remission of asthma, while subjects reporting allergic rhinitis (0.68 (0.51-0.90)), asthma onset ≤ 12 years of age (0.49 (0.35-0.68)), receiving treatment with antibiotics for respiratory illness (0.64 (0.47-0.87)) were less likely to have asthma remission. Factors related to a higher likelihood of remission of allergic rhinitis were no asthma at baseline, age ≥ 58 years in RHINE III, allergic rhinitis onset after 12 years of age, living in rural areas as a child, having only a primary school education and not being pregnant. CONCLUSION Clinical remission was found in almost one-half of those with asthma and one-third of persons with allergic rhinitis. Coexisting allergic symptoms were associated with less clinical asthma remission. Age, asthma symptoms and environmental factors in childhood, such as living in a rural area, were found to influence the clinical remission of allergic rhinitis.

Abstract
Background Long-term follow-up studies of adults with well-characterized asthma are sparse. We aimed to explore static lung volumes and diffusion capacity after 30 + years with asthma. Methods A total of 125 adults with an objectively verified diagnosis of asthma between 1974–1990 at a Danish respiratory outpatient clinic completed a follow-up visit 2017–19. All participants (age range 44–88 years) completed a comprehensive workup and were, based on these assessments, classified as having either active asthma or being in complete remission. The examination program included measurements of static lung volumes and diffusion capacity. Results Participants with active asthma were hyperinflated (residual volume/total lung capacity ratio 0.43, 95% CI 0.41—0.45) (RV/TLC ratio) compared with those in remission (RV/TLC ratio 0.38, 95% CI 0.36—0.41) (p < 0.03). A tendency towards higher diffusion capacity per liter lung volume was seen in participants with active asthma (KCO 100% predicted, 95% CI 97—104) compared with those in remission (KCO 94% pred., 95% CI 89—99) (P = 0.10). Longer asthma duration was associated with a higher KCO 0.47% pred./year (95% CI 0.14—0.80), adjusted for age and smoking. Patients on GINA step 4 and 5 treatment were more hyperinflated (\documentclass[12pt]{minimal}

Patients with uncontrolled disease had substantially higher airway resistance (72% pred. 95% CI 20—124) than well-controlled patients. Conclusion Thirty years after a confirmed diagnosis of asthma, those continuing to have active asthma and those having severe asthma, have higher diffusion capacity and more hyperinflation than patients in remission.

Abstract
Background There are no large sample, epidemiological data describing initial asthma severity and change. We used a large health care database to examine asthma severity at initial diagnosis, and the changes in severity over the first year of management. Methods The clinical data of patients diagnosed with asthma for the first time were collated from the SuValue electronic medical database. The following inclusion criteria were applied: (I) patients who were 14 years or older at the time of first diagnosis; (II) initial diagnosis occurred between Jan 2001 and Mar 2019; (III) patients were followed up for at least 12 months; (IV) patients had follow-up visits every 3 months. Disease severity at diagnosis and at each follow-up visit, medications prescribed were collated and analyzed. Results A total of 7,654 adult patients with newly diagnosed asthma from tertiary hospitals (26.38%) and secondary hospitals (73.62%), who were followed up for at least 12 months, were included in this retrospective analysis. Approximately 54% of patients were females and the largest age group was over 60 years old (37.66%). Nearly 16% of patients were moderate to severe asthma initially. The proportions of patients with moderate and severe asthma decreased during the first 6 months, and remained stable thereafter. At the end of the 1-year follow-up period, 2.7% of patients had severe asthma. Patients with mild asthma tended to continue to have mild asthma in the following 3 months (>76.19%). However, of the patients with mild or moderate asthma at 3 months, 92.85% and 75.1%, respectively, experienced maintenance and reduction in severity and had mild asthma by 12 months. 1.26% and 3.15% of patients with mild or moderate asthma, respectively, progressed to severe asthma by 12 months. Conclusions Patients with mild asthma did not progress but rather, remained stable with mild asthma over the year. A proportion of patients diagnosed with moderate and severe asthma remained stable over a 1-year period. Further studies should be conducted to examine the clinical features of newly diagnosed patients with severe asthma without reduction in severity in order to facilitate intensive treatment and reduce the disease burden for these patients.

Abstract
OBJECTIVE Uncontrolled asthma is associated with higher risk of hospital admissions and death. Low adherence to inhaled corticosteroid (ICS), the cornerstone of asthma therapy, is well-documented. Our aim was to investigate if hospital admission with an acute exacerbation of asthma changes ICS adherence. METHODS This retrospective cohort study comprises 241 patients hospitalized with an asthma exacerbation over 12 months (May 2019-April 2020). The primary outcome was proportion of ICS adherent patients, defined as Medication Possession Ratio (MPR) ≥80%, in the six-month period before and after admission. RESULTS The pre- to post-admission proportion of ICS adherent patients increased from 10% to 13% (p = 0.25) and the mean ICS MPR increased from 34% to 42% (p < 0.001). Different patterns of post-discharge adherence were observed, as adherent patients remained adherent, while patients with poor pre-admission adherence increased their adherence during two months after discharge followed by a decline in MPR. Co-variates such as sex, age, body mass index (BMI), GINA 2020-treatment step did not predict improvement in adherence after discharge. CONCLUSIONS Admission with an asthma exacerbation did not increase the proportion of patients adherent with controller medication, primarily ICS. Although an improvement in adherence was initially seen primarily in previously poorly adherent patients, this increase was transient as it decreased over time post-discharge.
