Abstract
Bronchiectasis is understood to be the result of a complex interaction between infection, impaired mucociliary clearance, inflammation, and lung damage. Current therapeutic approaches to bronchiectasis are heavily focused on management of infection along with enhancing mucus clearance. Long-term antibiotics have had limited success in clinical trials, suggesting a need to re-evaluate the concept of bronchiectasis as an infective disorder. We invoke the example of asthma, for which treatment paradigms shifted away from targeting smooth muscle constriction, towards permanently suppressing airway inflammation, reducing risk and ultimately inducing remission with precision anti-inflammatory treatments. In this Review, we argue that bronchiectasis is primarily a chronic inflammatory disease, requiring early identification of at-risk individuals, and we introduce a novel concept of disease activity with important implications for clinical practice and future research. A new generation of novel anti-inflammatory treatments are under development and repurposing of anti-inflammatory agents from other diseases could revolutionise patient care.

Abstract
INTRODUCTION The use of monoclonal antibodies in patients with severe asthma has led clinicians to explore new levels of clinical improvement, as testified by the growing interest on clinical remission achievement. In this context, a major role is played by asthma-related comorbidities, which can influence asthma pathophysiology and treatment response. AREAS COVERED In this special report, we highlighted how asthma-related comorbidities could deeply affect monoclonal antibody response as well as clinical remission achievement. As examples, we provided data from clinical trials and real-life experiences involving patients with severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic granulomatosis with polyangiitis (EGPA) or bronchiectasis. EXPERT OPINION Comorbidities associated with severe asthma development should be carefully assessed in everyday clinical practice, even with the help of new diagnostic technologies, artificial intelligence and multidisciplinary teams. Future studies should address the role of comorbidities in remission achievement, describing how these diseases could generate new trajectories of clinical and functional response in patient treated with monoclonal antibodies.

Real-world clinical remission of severe asthma with benralizumab in Spanish adults with severe asthma. J Asthma 2024:1-15. [PMID: 38520265 DOI: 10.1080/02770903.2024.2332351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 03/14/2024] [Indexed: 03/25/2024]
Abstract
OBJECTIVE Patients with severe eosinophilic asthma experience high risk of exacerbations and reduced quality of life. Benralizumab, a monoclonal antibody binding to IL-5 receptor α subunit, is an approved drug for its treatment. The objective was to describe clinical remission after benralizumab prescription in routine clinical practice. METHODS Retrospective multicenter study with data from four hospitals in Valencian Community (Spain) with asthma units between 2019 and 2020. Data was gathered at baseline and after 12 months. We considered clinical remission after 1 year if the patient remained without exacerbations and use of systemic corticosteroids and with good clinical control and normal lung function. RESULTS Data from 139 patients was gathered. At the 12-month follow-up, 44.1% were in clinical remission, since 84.0%, 77.5%, 51.0% and 95.5% of patients did not experience exacerbations, had total asthma control test score of ≥20, prebronchodilator FEV1 of ≥80% and did not use systemic corticosteroids. A significant reduction of long-acting muscarinic antagonists (p = 0.0001), leukotriene receptor antagonists (p = 0.0326), oral corticosteroids (p < 0.0001) and short-acting beta agonists (p = 0.0499) was observed. Baseline factors with greatest individual influence on clinical remission were employment situation, tobacco use, comorbidity number, eosinophil value, number of exacerbations, FEV1, emergency visit number, and ACT, MiniAQLQ and TAI scores. Final analysis of multiple logistic regression indicated that having baseline FEV1 value below 80% increases remission chance 9.7 times a year compared to FEV1 >80%. CONCLUSION Clinical remission after treatment with benralizumab is achievable in a high percentage of patients with severe asthma eosinophilia not controlled in real life.

Respir Med 2024; 222:107528. [PMID: 38199287 DOI: 10.1016/j.rmed.2024.107528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/05/2024] [Accepted: 01/07/2024] [Indexed: 01/12/2024]
Abstract
BACKGROUND The concept of remission on biological treatment has been suggested as a therapeutic target for patients with severe asthma, composed of 1. no chronic use of systemic steroids, 2. no exacerbations, 3. minimal symptoms, and 4. optimized lung function, for a significant time. However, the criteria for remission are not clearly defined. OBJECTIVE Our objective was to compare different criteria for remission in subjects receiving biologicals for severe asthma. METHODS A cross-sectional study of adult subjects who receive a stable regimen of a biological for severe asthma for at least 6-months. We compared the proportion of subjects who fulfilled different specific criteria in the four domains, as well as those who achieved different composite outcome measures of clinical remission. RESULTS Of 39 subjects, 28 were females (71.8%), mean age 60.4. Twelve were current or past smokers (30.8%). Twelve had prior different biological treatment (30.8%), and 3/39 had more than one previous treatment (7.7%). Current biological included mepolizumab 12/39 (30.8%), dupilumab 11/39 (28.2%), benralizumab 10/39 (25.6%), omalizumab 5/39 (12.8%), reslizumab 1/39 (2.6%). Different specific criteria were achieved in 39-80% of subjects, being highest for no chronic steroid use and lowest for symptoms control and lung function. Overall remission was obtained by 20-41%, depending on definition, with significant variability in agreement between different sets of remission criteria (Cohen's kappa 0.33-0.89). CONCLUSION Clinical remission is achievable in real-world severe asthmatics on biological therapies. The core criteria for remission should be better defined.

Abstract
Introduction Clinical remission (CliR) achievement has been recognized as a new potential outcome in severe asthma. Nevertheless, we still lack a detailed profile of what features could better identify patients undergoing clinical remission. In this study, we aim to address this issue, tracing a possible identikit of patients fulfilling remission criteria. Methods We enrolled 266 patients with severe eosinophilic asthma (SEA) treated with a 12-month course of anti-IL5/IL5 receptor (IL5r) monoclonal antibodies. Patients with no exacerbation, OCS withdrawal, ACT ≥ 20 and FEV1 ≥ 80% after 1 year of biologic treatment were classified as in clinical remission. Results 30.5% of the enrolled patients achieved remission after biologic administration. CliR group showed a lower number of baseline asthma exacerbations and better lung function parameters, with a trend for higher ACT scores and a less frequent history of a positive skin prick test. CliR achievement was unlikely in presence of a higher BMI, a positive skin prick test, an increased number of asthma exacerbations before biologic treatment, anti-muscarinic administration, and a previous diagnosis of EGPA, bronchiectasis or osteoporosis. In contrast, a better lung function, an increased blood eosinophilic count, the presence of chronic rhinosinusitis with nasal polyps and a more frequent use of reliever therapy predicts remission development. Changes in exacerbations number, OCS use, ACT scores and FEV1% between remittent and non-remittent patients arise at specific follow up timepoints and are positively associated with CliR achievement. Discussion anti-IL5/IL5r biologics can induce CliR in a proportion of patients with SEA. Patients achieving remission demonstrate specific clinical, functional and inflammatory features, as well as a specific moment of improvement in all the CliR items.

Abstract
INTRODUCTION Asthma is a global health problem, with alarming prevalence and mortality rates. Biologic therapies, particularly monoclonal antibodies such as omalizumab, have emerged as promising alternatives, targeting specific immune pathways. This article assesses the efficacy of these biologics in asthma management and attempts to reveal factors associated with their response and failure dynamics. AREA COVERED This article explores the efficacy of biologics in asthma, biomarkers, and the relationship between asthma phenotypes (including eosinophilic and non-eosinophilic (neutrophilic) types) and biologic treatments; particularly their effectiveness for each subtype. EXPERT OPINION Personalized asthma management that incorporates molecular insights as well as individual variations is of outmost necessity. An emphasis is put on immunological profiling, understanding comorbidities and considering individual patient factors when managing asthma. Cutting-edge phenotyping tools including omic technologies play a crucial role in improving asthma management precision. Variability in patient responses to biologic treatments such as non-responders, partial responders and super responders poses a formidable challenge to effective asthma care management strategies.

Abstract
Difficult-to-treat and severe asthma are challenging clinical entities. In the face of suboptimal asthma control, the temptation for clinicians is to reflexively escalate asthma-directed therapy, including increasing exposure to corticosteroids and commencement of costly but potent biologic therapies. However, asthma control is objectively and subjectively assessed based on measurable parameters (such as exacerbations or variability in pulmonary physiology), symptoms and patient histories. Crucially, these features can be confounded by common untreated comorbidities, affecting clinicians' assessment of asthma treatment efficacy.

Abstract
BACKGROUND Our study aimed to investigate whether serum total IgE and blood eosinophils were associated with radiological features of bronchiectasis in a Chinese cohort. METHODS We retrospectively enrolled bronchiectasis patients who visited Peking University Third Hospital from Jan 1st, 2012 to Oct 7th, 2021. The clinical, laboratory and chest CT characteristics were analyzed in association with serum total IgE level and blood eosinophil count. RESULTS A total of 125 bronchiectasis patients were enrolled, with 50.4% (63/125) female, and a mean age of 62.4 ± 14.1 years. The median serum total IgE level and blood eosinophil count were 47.7 (19.8, 123.0) KU/L and 140 (90, 230) cells/µl, respectively. In patients with a higher than normal (normal range, 0-60 KU/L) total IgE (43.2%, n = 54), more lobes were involved [4 (3, 5) vs. 3 (2, 4), p = 0.008], and mucus plugs were more common (25.9% vs. 9.9%, p =0.017) on HRCT, as compared to those with a normal level of total IgE. The higher IgE group was more likely to have bilateral involvement (p = 0.059), and had numerically higher Smith and Bhalla scores, but the differences were not statistically significant. In patients with an eosinophil count ≥ 150 cells/µl (49.6%, n = 62), the number of lobes involved was greater [4 (3, 5) vs. 3 (2, 4), p = 0.015], and the Smith and Bhalla scores were higher [9 (5, 12) vs. 6 (3, 9), p = 0.009, 7 (5, 11) vs. 5 (3, 9), p = 0.036]. The Smith score was correlated positively with the eosinophil count (r = 0.207, p = 0.020). Fractional exhaled nitric oxide (FeNO) was correlated with total IgE (r = 0.404, p = 0.001) and eosinophil count (r = 0.310, p = 0.014). CONCLUSIONS Our study demonstrated that serum total IgE and the blood eosinophil count were associated with the radiological extent and severity of bronchiectasis, necessitating further investigation on the role of T2 inflammation in structural abnormalities of this heterogeneous disease.
