J Asthma Allergy 2024; 17:681-691. [PMID: 39050030 PMCID: PMC11268766 DOI: 10.2147/jaa.s455911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 07/01/2024] [Indexed: 07/27/2024] Open
Abstract
Purpose Patients with asthma and low levels of type 2 inflammatory biomarkers (T2 low) have limited effective treatment options. Such biomarkers include eg blood eosinophils (b-eos) and fractional exhaled nitric oxide (FeNO). The healthcare resource utilisation (HCRU) of severe uncontrolled T2 low asthma remains unexplored. Thus, this study aimed to estimate the HCRU of T2 low and non-T2 low severe uncontrolled asthma patients using real-world data in Finland. Patients and Methods Adult patients with an asthma diagnosis during baseline (2012-2017) at the pulmonary department of Turku University Hospital were included and followed during 2018-2021, or until death. Total HCRU costs and respiratory-related HCRU costs were evaluated. The main drivers for the HCRU and costs were assessed with gamma and negative binomial regression models. Results Of the severe uncontrolled asthma patients with T2 status available, 40% (N=66) were identified with T2 low and 60% (N=103) with non-T2 low asthma. The average cumulative cost per patient was similar in patients with T2 low compared with non-T2 low, with all-cause costs cumulating in four years of follow-up to 37,524€ (95% CI: 27,160, 47,888) in T2 low compared to 34,712€ (25,484, 43,940) in non-T2 low. The corresponding average cumulative respiratory-related costs were 5178€ (3150, 7205) in T2 low compared to 5209€ (4104, 6313) in non-T2 low. Regression modelling identified no differences between the T2-status groups when assessing all-cause healthcare costs per patient-year (PPY). On the other hand, the regression modelling predicted more inpatient days PPY for severe uncontrolled patients with T2 low status compared to the patients with non-T2 low status. Conclusion Patients with uncontrolled severe T2 low asthma use equal healthcare resources as corresponding non-T2 low patients. This study brought new insights into the HCRU of severe uncontrolled asthma patients per T2 status, which has not previously been investigated.

Frequency and economic burden of exacerbations in inhaled corticosteroid/long-acting beta-agonist-treated patients with asthma: A retrospective US claims study. Respir Med 2024; 226:107629. [PMID: 38593885 DOI: 10.1016/j.rmed.2024.107629] [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: 11/10/2023] [Revised: 03/15/2024] [Accepted: 04/06/2024] [Indexed: 04/11/2024]
Abstract
INTRODUCTION Despite adherence to inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) therapy, many patients with asthma experience moderate exacerbations. Data on the impact of moderate exacerbations on the healthcare system are limited. This study assessed the frequency and economic burden of moderate exacerbations in patients receiving ICS/LABA. METHODS Retrospective, longitudinal study analyzed data from Optum's de-identified Clinformatics® Data Mart Database recorded between October 1, 2015, and December 31, 2019. Eligibility criteria included patients ≥18 years of age with ≥1 ICS/LABA claim and ≥1 medical claim for asthma in the 12 months pre-index (first ICS/LABA claim). Primary objectives included describing moderate exacerbation frequency, and associated healthcare resource utilization (HRU) and costs. A secondary objective was assessing the relationship between moderate exacerbations and subsequent risk of severe exacerbations. Patients were stratified by moderate exacerbation frequency in the 12 months post index. Moderate exacerbations were identified using a newly developed algorithm. RESULTS In the first 12 months post index 61.6% of patients experienced ≥1 moderate exacerbation. Mean number of asthma-related visits was 4.1 per person/year and median total asthma-related costs was $3544. HRU and costs increased with increasing exacerbation frequency. Outpatient and inpatient visits accounted for a similar proportion of these costs. Moderate exacerbations were associated with an increased rate and risk of future severe exacerbations (incidence rate ratio, 1.56; hazard ratio, 1.51 [both p < 0.001]). CONCLUSIONS This study highlighted that a high proportion of patients continue to experience moderate exacerbations despite ICS/LABA therapy and subsequently experience increased economic burden and risk of future severe exacerbations.

An examination of factorial invariance of the Asthma Control Questionnaire among adults with severe asthma. PLoS One 2023; 18:e0295493. [PMID: 38060586 PMCID: PMC10703262 DOI: 10.1371/journal.pone.0295493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 11/22/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND The Asthma Control Questionnaire (ACQ) is used to assess asthma symptom control. The relationship between the questionnaire items and symptom control has not been fully studied in severe asthmatic patients, and its validity for making comparisons between subgroups of patients is unknown. METHODS Data was obtained from patients in the United Kingdom Severe Asthma Registry whose symptom control was assessed using the five-item ACQ (ACQ5) (n = 2,951). Confirmatory factor analysis determined whether a latent factor for asthma symptom control, as measured by the ACQ5, was consistent with the data. Measurement invariance was examined in relation to ethnicity, sex and age; this included testing for approximate measurement invariance using Bayesian Structural Equation Modelling (BSEM). The fitted models were used to estimate the internal consistency reliability of the ACQ5. Invariance of factor means across subgroups was assessed. RESULTS A one-factor construct with residual correlations for the ACQ5 was an excellent fit to the data in all subgroups (Root Mean Square Error Approximation 0.03 [90%CI 0.02,0.05], p-close fit 0.93, Comparative Fit Index 1.00, Tucker Lewis Index 1.00}. Expected item responses were consistent for Caucasian and non-Caucasian patients with the same absolute level of symptom control. There was some evidence that females and younger adults reported wakening more frequently during the night than males and older adults respectively with the same absolute level of symptom control (p<0.001). However approximate measurement invariance was tenable and any failure to observe strong measurement invariance had minimal impact when comparing mean levels of asthma symptom control between patients of different sexes or ages. Average levels of asthma symptom control were lower for non-Caucasians (p = 0.001), females (p<0.01)and increased with age (p<0.01). Reliability of the instrument was high (over 88%) in all subgroups studied. CONCLUSION The ACQ5 is informative in comparing levels of symptom control between severe asthmatic patients of different ethnicities, sexes and ages. It is important that analyses are replicated in other severe asthma registries to determine whether measurement invariance is observed.

Abstract
Aim The International Severe Asthma Registry (ISAR; http://isaregistries.org/) uses standardised variables to enable multi-country and adequately powered research in severe asthma. This study aims to look at the data countries within ISAR and non-ISAR countries reported collecting that enable global research that support individual country interests. Methods Registries were identified by online searches and approaching severe asthma experts. Participating registries provided data collection specifications or confirmed variables collected. Core variables (results from ISAR's Delphi study), steroid-related comorbidity variables, biologic safety variables (serious infection, anaphylaxis, and cancer), COVID-19 variables and additional variables (not belonging to the aforementioned categories) that registries reported collecting were summarised. Results Of the 37 registries identified, 26 were ISAR affiliates and 11 non-ISAR affiliates. Twenty-five ISAR-registries and 4 non-ISAR registries reported collecting >90% of the 65 core variables. Twenty-three registries reported collecting all optional steroid-related comorbidity variables. Twenty-nine registries reported collecting all optional safety variables. Ten registries reported collecting COVID-19 variables. Twenty-four registries reported collecting additional variables including data from asthma questionnaires (10 Asthma Control Questionnaire, 20 Asthma Control Test, 11 Asthma Quality of Life Questionnaire, and 4 EuroQol 5-dimension 5-level Questionnaire). Eight registries are linked to databases such as electronic medical records and national claims or disease databases. Conclusion Standardised data collection has enabled individual severe asthma registries to collect unified data and increase statistical power for severe asthma research irrespective of ISAR affiliations.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:2715-2723. [PMID: 37245734 DOI: 10.1016/j.jaip.2023.05.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 05/05/2023] [Accepted: 05/16/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND Biologic therapies such as mepolizumab and benralizumab offer treatment options for severe eosinophilic asthma (SEA), although long-term real-world data on their use are limited. OBJECTIVES To evaluate the impact of benralizumab and mepolizumab treatment among biologic-naive patients with SEA over 36 months and describe the incidence of super-response at 12 and 36 months, identifying potential predictive factors. METHODS We conducted a retrospective, single-center study of patients with SEA who were given mepolizumab or benralizumab from May 2017 to December 2019, and who completed 36 months of therapy. Baseline demographics, comorbidities, and medication use were described. Data on clinical outcomes, including maintenance oral corticosteroid (OCS) use, annual exacerbation rate (AER), mini Asthma Quality of Life Questionnaire, Asthma Control Questionnaire (ACQ-6), and eosinophil count were collected at baseline and at 12 and 36 months. Super-response was evaluated at 12 and 36 months. RESULTS A total of 81 patients were included. Maintenance OCS use significantly improved from baseline (5.3 mg/d) to 12 months (2.4 mg/d, P < .0001) and 36 months (0.6 mg/d; P < .0001). Annual exacerbation rate decreased from baseline (5.8) to 12 months (0.9; P < .0001) and 36 months (1.2; P < .0001). Mini Asthma Quality of Life Questionnaire, ACQ-6, and eosinophil count significantly improved from baseline to 12 and 36 months. Twenty-nine patients demonstrated super-response at 12 months. Compared with those without a super-response, these patients had better baseline AER (4.7 vs 6.5; P = .009), mini Asthma Quality of Life Questionnaire (3.41 vs 2.54; P = .002), and ACQ-6 (3.38 vs 4.06; P = .03) scores. Most maintained a super-response up to 36 months. CONCLUSIONS Mepolizumab and benralizumab are associated with significant improvements in OCS use, AER, and asthma control in real-world cohorts for up to 36 months, providing insight into long-term use for SEA.

Abstract
Aims. To evaluate the cost-effectiveness of standard-of-care treatment (SoC) to SoC in combination with omalizumab (OML + Soc) in patients with severe asthma using real-world prospective clinical data from 4 major medical centers in Turkey.Materials and methods. Between February 2018 and November 2019, a total of 206 patients with severe astma, including 126 of whom were in the OML + SoC group and 80 in the SoC group, were followed for 12 months to evaluate their asthma status and quality of life. Cost data for this patient-level economic evaluation were sourced from the MEDULA database of the hospitals and expressed in Turkish Lira (₺). Efficacy data were obtained by means of Turkish versions of the Asthma Control Test for asthma status, and the 5-level EQ-5D-5L version (EQ-5D-5L) and the Asthma Quality of Life Scale for quality of life. A Markov model with 2-week cycles was specified, comparing costs and treatment effects of SoC versus OML + SoC over a lifetime from the Turkish payer perspective.Results. Per-patient costs were ₺23,607.08 in the SoC arm and ₺425,329.81 in the OML + Soc arm, for a difference of ₺401,722.74. Life years (LY) and quality-adjusted life years (QALY) were 13.60 and 10.08, respectively, in the SoC group; and 21.26 and 13.35, respectively, in the OML + SoC group, for differences of 7.66 LYs and 3.27 QALYs. This yielded an incremental cost-effectiveness ratio of an additional ₺52,427.04 to gain 1 LY and an incremental cost-utility ratio of an incremental ₺122,675.57 to gain 1 QALY; the latter being below the ₺156,948 willingness-to-pay threshold for Turkey referenced by WHO. One-way and multivariate sensitivity analyses confirmed that base-case results.Conclusion. Whereas most economic evaluations are based on aggregate data, this independent cost-effectiveness analysis using prospective real-world patient-level data suggests that omalizumab in combination with standard-of-care is cost-effective for severe asthma from the Turkish public payer perspective.

[PMID: 36841360 DOI: 10.1016/j.rmed.2023.107170] [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: 12/15/2022] [Revised: 02/19/2023] [Accepted: 02/21/2023] [Indexed: 02/27/2023]
Abstract
BACKGROUND Some patients with severe asthma do not achieve sufficient symptom control despite guideline-based treatment, and therefore receive oral (OCS) and systemic corticosteroids (SCS) on regular basis. The side effects of corticosteroid use negatively impact patients' health-related quality of life (HRQoL) and increase the disease burden. Biologics have shown promise in asthma therapy; however, identifying patients who might benefit from biologic therapy is complex due to the heterogeneous pathophysiology of the disease. METHODS The European, non-interventional, multicentre RECOGNISE study (NCT03629782) assessed patient characteristics, asthma medication and control, HRQoL as assessed by St. George's Respiratory Questionnaire (SGRQ), and health care resource use in patients with severe asthma, as well as their eligibility for biologic treatment. Here, data from the Greek cohort (N = 97) are reported. RESULTS In Greece, patients with severe asthma were more often female (71%) and never smokers (68%). 87% of patients were assessed as eligible for biologic treatment by investigator's judgement (per label criteria: 76%). Most patients had been previously treated with SCS (82% eligible vs 85% non-eligible), with OCS use being more common in non-eligible patients (23.1% vs 11.9%). More eligible patients had poorly controlled asthma (76% vs 54%), and more impaired HRQoL (mean total SGRQ score: 46% vs 39%); symptom burden was significantly higher (mean symptom score: 60% vs. 44%, p: 0.0389). CONCLUSIONS A high proportion of Greek patients with severe asthma are eligible for biologic therapy; however, individual risk factors and differences between asthma types must be considered before the introduction of targeted therapy.

Abstract
Severe asthma (SA), chronic rhinosinusitis with nasal polyps (CRSwNP), and eosinophilic granulomatosis with polyangiitis (EGPA) are three conditions driven by IL-5 and eosinophilic inflammation. As these conditions have high use of healthcare services, as well as lifestyle and psychological burdens, safe treatment to achieve optimal control is key. In all three conditions, as for many other eosinophilic diseases (ED), oral corticosteroids (OCS) are often used for both acute and maintenance treatment where disease activity is high. While, in general, OCS are very effective, their use is limited by a well-recognised high potential for adverse effects (AE). Moreover, cumulative exposure to OCS may not be acknowledged in many patients, especially for those predominantly treated in primary care, exposing patients to potentially damaging long-term OCS-related AEs. To discuss the use of OCS for these eosinophilic diseases, as well as to provide guidance on how to help limit their use, a board of European experts within each field was gathered. The experts completed questionnaires regarding treatment and referral pathways for patients with SA, CRSwNP, or EGPA; then, in an online meeting, discussed a number of issues in regard to OCS use. Here, the authors present the key recommendations from the expert advisory panel alongside some background to these conditions regarding treatment with OCS.

Abstract
INTRODUCTION Allergic asthma has variable characteristics depending on the region of occurrence. Management is often organized without easy access to a specialized pneumo-allergological evaluation. OBJECTIVES PRIMARY: To characterize allergic asthma in patients followed at the Nancy University Hospital. SECONDARY To estimate the impact at 12 months of the proposed specialized management. METHOD Retrospective study including allergic asthmatic adults conducted between 01/01/2016 and 31/12/2018. Parameters studied (aside from descriptive parameters): asthma control score ACQ-7 (Asthma Control Questionnaire) and lung function at inclusion and at one year. RESULTS One hundred and fifteen patients were included (age 42±16 years, women 63%, non-smokers 70%). Even though asthma symptoms arose at 19±18 years, the specialized consultation was performed 21±17.5 years later. Frequent sensitizations involved house dust mites (49%), cat dander (43%), grasses (43%). Patients tended to underestimate the frequency of their allergies (mites 36% P=0.011, pollens 36% P=0.001, pet dander 42% P=0.003, molds 80% P=0.007). At 1-year follow-up both the ACQ-7 score (1.3±1.3 vs. 0.8±0.9; P=0.007) and the forced expiratory volume per second (81.3±20.8% vs. 86.2±21.9%; P=0.002) had improved. CONCLUSION The specificities of allergic asthmatics followed up in Nancy: late age of asthma onset of asthma and specialized consultation; predominant sensitization to cat dander and Betulaceae pollens; underestimation of allergies by the patient. Specialized care seems to important in the management of allergic asthma. While access to specialized care remains problematic, it could be facilitated by the creation of dedicated networks.

Abstract
BACKGROUND Biological therapies have revolutionized the treatment of severe asthma with type 2 inflammation. Although such treatments are very effective in reducing exacerbation and the dose of oral steroids, little is known about the persistence of symptoms in severe asthma patients treated with biologics. PURPOSE We aim to describe asthma control and healthcare consumption of severe asthma patients treated with biologics. DESIGN The Second Souffle study is a real-life prospective observational study endorsed by the Clinical Research Initiative in Severe Asthma: a Lever for Innovation & Science Network. METHODS Adults with a confirmed diagnosis of severe asthma for at least 12 months' duration were enrolled in the study. A self-administered questionnaire including the Asthma Control Questionnaire (ACQ), Asthma Quality of Life Questionnaire (AQLQ) and a compliance evaluation test was given to the patients. Healthcare consumption within 12 months prior to enrolment was documented. In patients receiving biologics, doctors indicated whether the patients were biologic responders or non-responders. RESULTS The characteristics of 431 patients with severe asthma were analysed. Among them, 409 patients (94.9%) presented asthma with type 2 inflammation (T2 high) profile, and 297 (72.6%) patients with a T2 high phenotype were treated with a biologic. Physicians estimated that 88.2% of patients receiving biologics were responders. However, asthma control was only achieved in 25.3% of those patients (ACQ > 0.75). A high proportion of patients (77.8%) identified as responders to biologics were not controlled according to the ACQ score. About 50% of patients continue to use oral corticosteroids either daily (25.2%) or more than three times a year for at least three consecutive days (25.6%). Gastro-oesophageal Reflux Disease (GERD) and Obstructive Sleep Apnoea syndrome (OSA) were identified as independent factors associated with uncontrolled asthma. CONCLUSION Although a high proportion of severe asthma patients respond to biologics, only 25.3% have controlled asthma. GERD and OSA are independent factors of uncontrolled asthma.

Abstract
BACKGROUND Data on health care consumption and costs of asthma in the French population are scarce. OBJECTIVES The study objective was to describe the burden of asthma according to GINA treatment steps in the CONSTANCES cohort. METHODS Data from 162,725 participants included between 2012 and 2019 were extracted. Participants were considered as current asthmatics if asthma was reported at inclusion and asthma symptoms and/or treatments were reported in 2019. Participants were classified in three categories according to GINA treatment steps. The results were compared to non-asthmatic participants matched with a propensity score calculated on age, sex, region of residence, precariousness score and year of inclusion. RESULTS Among 162,725 participants aged 18-69 years, 6783 asthmatics (1566 not treated for asthma, 2444 + 251 GINA steps 1 + 2, 1054 + 1315 GINA steps 3 + 4, and 153 GINA step 5) were matched with 6783 controls. Average annual ambulatory cost and average annual hospitalization cost were respectively €1925 and €719 for asthmatics versus €1376 and €511 for participants without asthma (p < 0,0001). Cardiovascular risk factors, co-morbidities, visits and hospitalizations were higher for asthma participants as compared to controls and increased with GINA steps, as well as inpatient and outpatient costs. However, for cardiovascular risk factors and co-morbidities, differences were non-significant in multivariate analyses. Pharmacy costs were ten times higher for GINA step 5 participants than for GINA steps 1-2 participants: €3187 versus €393 (p < 0,0001). CONCLUSION mean cost of asthma was estimated at €757 per patient/year and increased with GINA treatment step.

Abstract
Asthma is a multifactorial disease with complex pathophysiology. Knowledge of its immunopathology and inflammatory mechanisms is progressing and has led to the development over recent years of increasingly targeted therapeutic strategies. The objective of this review is to pinpoint the different predictive markers of asthma severity and therapeutic response. Obesity, nasal polyposis, gastroesophageal reflux disease and intolerance to aspirin have all been considered as clinical markers associated with asthma severity, as have functional markers such as bronchial obstruction, low FEV1, small daily variations in FEV1, and high FeNO. While sinonasal polyposis and allergic comorbidities are associated with better response to omalizumab, nasal polyposis or long-term systemic steroid use are associated with better response to antibodies targeting the IL5 pathway. Elevated total IgE concentrations and eosinophil counts are classic biological markers regularly found in severe asthma. Blood eosinophils are predictive biomarkers of response to anti-IgE, anti-IL5, anti-IL5R and anti-IL4R biotherapies. Dupilumab is particularly effective in a subgroup of patients with marked type 2 inflammation (long-term systemic corticosteroid therapy, eosinophilia≥150/μl or FENO>20 ppb). Chest imaging may help to identify severe patients by seeking out bronchial wall thickening and bronchial dilation. Study of the patient's environment is crucial insofar as exposure to tobacco, dust mites and molds, as well as outdoor and indoor air pollutants (cleaning products), can trigger asthma exacerbation. Wider and more systematic use of markers of severity or response to treatment could foster increasingly targeted and tailored approaches to severe asthma.

Abstract
BackgroundNotwithstanding unequivocal consensus on the disproportionate effect of severe asthma (SA) on asthma morbidity, healthcare utilisation, quality of life, work impairment and socioeconomic burden, the burden of SA patients in Singapore has not been appraised.ObjectivesTo determine the burden of disease and extent of quality of life impairment in SA patients in Singapore.MethodsA cross-sectional analysis of SA patients seen in Singapore General Hospital (2020-2021) to investigate emergency healthcare utilization, oral corticosteroid (OCS) burden and health-related quality of life (HRQoL) with primary endpoint EuroQoL-5 Dimension three-level (EQ-5D-3L) scores. The empirical measurement properties of the EQ-5D utility index in SA were comprehensively assessed through multivariate regression analyses.ResultsA total of 336 SA patients were recruited, 51.2% of SA patients had at least one acute healthcare resource utilization during the previous year, with 25.6% of patients having an emergency healthcare visit to the hospital. Overall mean (SD) EQ-5D-3L and EQ-5D-3L utility scores in SA patients were 6.22 (1.51) and 0.77 (0.30), respectively. EQ-5D utility scores were 0.14 lower in uncontrolled vs controlled asthma and 0.09 lower in the presence of severe exacerbation, whereas barely changed by maintenance OCS dose and airflow limitation.ConclusionSA patients were found to have high disease burden, high healthcare resource utilization and OCS use, low biologics usage, poor HRQoL and utility in comparison with other chronic diseases.

Abstract
Airway remodeling is a frequent pathological feature of severe asthma leading to permanent airway obstruction in up to 50% of cases and to respiratory disability. Although structural changes related to airway remodeling are well-characterized, immunological processes triggering and maintaining this phenomenon are still poorly understood. As a consequence, no biotherapy targeting cytokines are currently efficient to treat airway remodeling and only bronchial thermoplasty may have an effect on bronchial nerves and smooth muscles with uncertain clinical relevance. Th17 cytokines, including interleukin (IL)-17 and IL-22, play a role in neutrophilic inflammation in severe asthma and may be involved in airway remodeling. Indeed, IL-17 is increased in sputum from severe asthmatic patients, induces the expression of "profibrotic" cytokines by epithelial, endothelial cells and fibroblasts, and provokes human airway smooth muscle cell migration in in vitro studies. IL-22 is also increased in asthmatic samples, promotes myofibroblast differentiation, epithelial-mesenchymal transition and proliferation and migration of smooth muscle cells in vitro. Accordingly, we also found high levels of IL-17 and IL-22 in a mouse model of dog-allergen induced asthma characterized by a strong airway remodeling. Clinical trials found no effect of therapy targeting IL-17 in an unselected population of asthmatic patients but showed a potential benefit in a sub-population of patients exhibiting a high level of airway reversibility, suggesting a potential role on airway remodeling. Anti-IL-22 therapies have not been evaluated in asthma yet but were demonstrated efficient in severe atopic dermatitis including an effect on skin remodeling. In this review, we will address the role of Th17 cytokines in airway remodeling through data from in vitro, in vivo and translational studies, and examine the potential place of Th17-targeting therapies in the treatment of asthma with airway remodeling.

Abstract
BACKGROUND Approval of biologics has recently revolutionized T2 severe asthma management. However, predictive biomarkers remain highly needed to improve patient's selection. OBJECTIVE This study aims to determine whether serum immunoglobulins (Igs) levels might be predictive biomarkers of response to anti-interleukin-5 (IL5)/IL5Rα therapies. METHODS Severe asthma patients eligible for mepolizumab or benralizumab were included herein. Serum immunoglobulin quantification was performed at baseline before mepolizumab or benralizumab initiation. After a 6-month treatment of mepolizumab or benralizumab, patients presented a second serum immunoglobulin quantification. The treatment response was evaluated by the GETE (Global Evaluation of Treatment Effectiveness) score at 6 months. RESULTS A total of 50 patients were included. Median age was 56 [IQR 48.8-65.3] and 50% were females. Compared to baseline, a significant increase in IgG was observed at 6 months (9.2 [7.8-10.2] g/l vs 10.1 [8.8-11.1] g/l, p = 0.04). The area under the ROC curve was 0.58 [95%IC 0.40-0.77] for blood eosinophil count (p = 0.37), 0.75 [95%IC: 0.58-0.92] for serum IgG concentration (p = 0.009) for predicting the treatment response. According to the Youden index, serum IgG concentration ≥ 9.2 g/l predicts the response to anti-IL5 therapies with a sensitivity of 76.9% and a specificity of 75.7%. CONCLUSION Baseline serum IgG concentrations may be a useful tool to predict the response to anti-IL5/IL5Rα therapies but should be confirmed in larger clinical trials. Interestingly, anti-IL5/IL5Rα therapies are associated with a significant increase in serum IgG concentrations at 6 months.

Self-reported asthma prevalence and management in adults in France in 2018: ASTHMAPOP survey. Respir Med Res 2021; 80:100864. [PMID: 34773824 DOI: 10.1016/j.resmer.2021.100864] [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: 12/18/2020] [Revised: 08/26/2021] [Accepted: 10/08/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND There is a paucity of epidemiological data on asthma classified by disease severity in France. The ASTHMAPOP cross-sectional study aimed to review the prevalence and current management of asthma in people aged ≥18 years in France. METHODS A self-administered questionnaire was mailed to 19 676 people representative of the French population in age, gender, region, and socio-economic status. Asthma was classified by treatment steps per the 2017 Global Initiative for Asthma (GINA) report, according to prescribed treatments. Analyses were mostly descriptive. RESULTS The questionnaire return rate was 81.7% (n = 16 083), and 15 587 questionnaires were analyzed. The prevalence of lifetime asthma was 12.8% (95% confidence interval (CI):12.3-13.3%; n = 1 989) in 2018. The prevalence of current asthma (i.e., 12 months before the survey) was 6.4% (95% CI: 6.0-6.8%; n = 993); most of these respondents (95.3% [n = 946]) were receiving asthma treatment, and 49.4% (n = 491) were treated for mild asthma (GINA step 1 or 2). Of people with current asthma, 47.6% reported ≥1 asthma exacerbation in the past 12 months-defined as episodes (several days) during which symptoms (cough, sputum, and dyspnea) were worse than usual; 14.3% had ≥1 emergency visit, and 3.1% had ≥1 hospitalization due to asthma. Of those taking continuous asthma controller medications who answered all Morisky Medication Adherence Scale questions (n = 501), 46.4% were adherent (score=4) to their treatment regimen. Based on the 6-item Asthma Control Questionnaire scores, asthma was partially controlled or uncontrolled in 47.7% of 969 people. CONCLUSIONS The prevalence of asthma in France has remained stable since 2006, but levels of asthma control and treatment adherence continue to be relatively poor. Asthma management in France requires improvement.

Anti-interleukin 5 therapies failure criteria in severe asthma: a Delphi-consensus study. Ther Adv Respir Dis 2021; 15:17534666211049735. [PMID: 34629000 PMCID: PMC8504226 DOI: 10.1177/17534666211049735] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Background: Current practices for assessing response to anti-interleukin 5/R treatment in severe asthma patients are heterogeneous. The objective of this study was to achieve an expert consensus defining failure criteria for anti-interleukin 5/R treatment in severe asthma patients. Methods: Experts were invited to a 5-round Delphi exercise if they were pulmonologists managing ⩾30 patients at a nationally recognized severe asthma expert centre. Following two rounds of statement-generating brainstorming, the expert panel ranked each statement according to a 5-point Likert-type scale during three additional rounds. Positive consensus was considered achieved when ⩾80% of experts agreed with a statement with >50% strong agreement and <15% disagreement. Results: Twenty experts participated in the study. All experts agreed that predefined treatment goals defining effectiveness should be personalized during shared decision making via a patient contract. Treatment failure was defined as (1) absence of a reduction in exacerbation rates by ⩾25% or (2) absence of a reduction in oral corticosteroid therapy by ⩾25% of the initial dosage or (3) occurrence of emergency room visits or hospitalizations after 6 months of treatment. Treatment failure should result in discontinuation. For partial responders, treatment discontinuation was not recommended unless an alternative from another therapeutic class exists and should be discussed in a multidisciplinary consultation. Conclusion: The present study provides objective criteria for anti IL5 or IL5R failure in severe asthma and suggests consensus based guidelines for prescription, evaluation and discontinuation decision-making.

Abstract
Over 330 million people have been diagnosed with asthma worldwide [1], of whom 5–10% are classified as severe [2]. Despite use of high doses of inhaled corticosteroids (ICS), long-acting bronchodilators (LABA) and/or maintenance oral steroid use, patients with severe asthma account for over 50% of the asthma healthcare budget [3, 4]. Largely due to exacerbations requiring hospitalisation, and cost of treatments to control disease severity, the disease burden has serious implications for their health and quality of life [3–5]. Heightened capsaicin cough sensitivity is independently associated with poor asthma control in moderate-to-severe asthma patientshttps://bit.ly/3mkbLkI

Abstract
Severe asthma imposes a significant burden on individuals, families and the healthcare system. Treatment is complex, due to disease heterogeneity, comorbidities and complexity in care pathways. New approaches and treatments improve health outcomes for people with severe asthma. However, emerging multidimensional and targeted treatment strategies require a reorganisation of asthma care. Consensus is required on how reorganisation should occur and what areas require further research. The Centre of Excellence in Severe Asthma convened three forums between 2015 and 2018, hosting experts from Australia, New Zealand and the UK. The forums were complemented by a survey of clinicians involved in the management of people with severe asthma. We sought to: (i) identify areas of consensus among experts; (ii) define activities and resources required for the implementation of findings into practice; and (iii) identify specific priority areas for future research. Discussions identified areas of unmet need including assessment and diagnosis of severe asthma, models of care and treatment pathways, add-on treatment approaches and patient perspectives. We recommend development of education and training activities, clinical resources and standards of care documents, increased stakeholder engagement and public awareness campaigns and improved access to infrastructure and funding. Further, we propose specific future research to inform clinical decision-making and develop novel therapies. A concerted effort is required from all stakeholders (including patients, healthcare professionals and organisations and government) to integrate new evidence-based practices into clinical care and to advance research to resolve questions relevant to improving outcomes for people with severe asthma.

Abstract
BACKGROUND: Severe asthma is a major burden on health-economic resources; hence, knowing the epidemiology of these patients is important in planning and provision of asthma care. In addition, identifying and managing the comorbidities helps improve symptoms and reduce associated morbidity and mortality. OBJECTIVES: Epidemiology of difficult asthma has not been well studied in the Middle East, so in this study, we present the demographic and clinical characteristics of severe asthma in the United Arab Emirates (UAE). METHODS: We retrospectively reviewed the notes of severe asthma patients attending three tertiary care hospitals between May 2015 and December 2019. Data on baseline demographics, asthma characteristics, treatment, and comorbidities were collected. RESULTS: We reviewed the notes of 458 patients (271 females and 187 males) that fulfilled the 2019 Global Initiative for Asthma guidelines for the diagnosis of severe asthma. The mean age was 47.7 (standard deviation 17.2) years. Males had significantly higher asthma control test scores (17.9 vs. 16, P = 0.01) and mean blood eosinophils (0.401 vs. 0.294, P <0.01) than females. The most common comorbidity observed was allergic rhinitis (52.2%) followed by gastroesophageal reflux disease (27.1%). In total, 109 (23.8%) patients were on biological therapies with most patients being on omalizumab and dupilumab (29 and 18 patients, respectively). Most patients were nonsmokers (97.2%), and majority were of TH2-high phenotype (75.7%). CONCLUSIONS: In this first report of severe asthma characteristics in the UAE, we found a pattern of female preponderance and most patients having a Th2-high phenotype. The findings are likely to help optimize asthma care in the region in the era of biologic therapies.

Abstract
According to the data derived from several national and international registries, including SANI (Severe Asthma Network Italy), and considering the strong impact that frequent or regular use of oral corticosteroid has on quality of life (QoL) of severe asthmatics, as well as on the costs for managing corticosteroid-related diseases, oral corticosteroid sparing up to withdrawal should be considered a primary outcome in the management of severe asthma. New biologics have clearly demonstrated that this effect is possible, with concomitant reduction in the rate of exacerbations and in symptom control. Then, there is no reason for using so frequently oral corticosteroid before having explored all alternatives currently available for a large part of severe asthmatics.

Abstract
Background The links between microbial environmental exposures and asthma are well documented, but no study has combined deep sequencing results from pulmonary and indoor microbiomes of patients with asthma with spirometry, clinical, and endotype parameters. Objective The goal of this study was to investigate the links between indoor microbial exposures and pulmonary microbial communities and to document the role of microbial exposures on inflammatory and clinical outcomes of patients with severe asthma (SA). Methods A total of 55 patients with SA from the national Cohort of Bronchial Obstruction and Asthma cohort were enrolled for analyzing their indoor microbial flora through the use of electrostatic dust collectors (EDCs). Among these patients, 22 were able to produce sputum during “stable” or pulmonary “exacerbation” periods and had complete pairs of EDC and sputum samples, both collected and analyzed. We used amplicon targeted metagenomics to compare microbial communities from EDC and sputum samples of patients according to type 2 (T2)-asthma endotypes. Results Compared with patients with T2-low SA, patients with T2-high SA exhibited an increase in bacterial α-diversity and a decrease in fungal α-diversity of their indoor microbial florae, the latter being significantly correlated with fraction of exhaled nitric oxide levels. The β-diversity of the EDC mycobiome clustered significantly according to T2 endotypes. Moreover, the proportion of fungal taxa in common between the sputum and EDC samples was significantly higher when patients exhibited acute exacerbation. Conclusion These results illustrated, for the first time, a potential association between the indoor mycobiome and clinical features of patients with SA, which should renew interest in deciphering the interactions between indoor environment, fungi, and host in asthma.

Abstract
OBJECTIVE The economic burden of severe asthma (SA) in children is poorly described. We aimed to determine the healthcare costs of SA in children for the French national health insurance (NHI). METHODS Children (6-18 years of age) with physician-confirmed diagnoses of SA or non-SA (NSA) were identified. Direct and indirect expenditures related to asthma and associated co-morbidities in the previous six months were determined, based on a physician-guided parental questionnaire and confirmed by medical records. The costs for the French NHI were assessed per child over a six month period. RESULTS Data from 74 children, including 48 with SA (22 requiring omalizumab) and 26 with NSA, were analyzed. The global cost of SA was €3,982 per child over a six-month period, including €3,821 direct costs and €161.9 indirect costs. The global cost was €6,716 (4,220) for those requiring omalizumab vs. €1,669 (3,108) for those who did not (p < 0.01). For children with SA, 65% of direct costs were attributed to medication. Among those on omalizumab, such treatment accounted for 93% of medication costs. The global cost was 10 times higher for children with SA than those with NSA (€3,982 (4,422) vs. €363.2 (352.6), p < 0.01), and 20 times higher for children with SA on omalizumab than those with NSA (p < 0.01). CONCLUSION The economic burden of SA in children for the French NHI is substantial and mainly driven by the most severe children requiring biologics.

Abstract
OBJECTIVE To assess the efficacy and safety of omalizumab in children with moderate-to-severe asthma.Data sources: We systematically searched MEDLINE, EMBASE, and Cochrane for randomized controlled trials (RCTs ) (inception to January 2020).Study selections: All RCTs which were conducted in childhood and adolescence with asthma and compared the efficacy or safety of omalizumab were adopted. RESULTS Three studies with four publications including 1380 pediatric patients met our criteria. For children with moderate-to-severe asthma, omalizumab decreased asthma exacerbations rate (OR 0.51, 95% CI: 0.44-0.58, p < 0.001) compared with placebo with no evidence of heterogeneity. Omalizumab reduced the rate of asthma exacerbations 0.58) with treatment period ≥30 weeks (p for heterogeneity = 0.03). Omalizumab treated patients had an excellent or good response rate of treatment effectiveness assessed by physicians (2.75, 2.45-3.09) and a bigger reduction in the dosage of inhaled corticosteroid (ICS) at the end of follow-up. For children with severe asthma, omalizumab also reduced the likelihood of asthma exacerbations and increased the odd of treatment effectiveness rated as excellent or good. Patients receiving omalizumab had a lower incidence of severe adverse events (0.36, 0.22-0.57). CONCLUSIONS These findings suggested that omalizumab had beneficial effects on moderate-to-severe asthma in children. Patients may benefit more from long-term use of omalizumab. In addition, omalizumab reduces the rate of serious adverse events requiring hospitalizations.

Abstract
Background: Severe asthma (SA) database was established in Hungary to estimate the prevalence of SA and to define and analyze clinical phenotypes of the patients. Methods: SA questionnaires were sent out to 143 public pulmonary dispensaries specialized for diagnosing and caring pulmonary patients. Data of 520 SA patients were evaluated. Results: The prevalence of SA within the asthmatic population in Hungary was 0.89%. The mean age of patients were 56.4 ± 13.4 years, SA were more frequent in females (64%), the prevalence of allergy was 56.6%, 72.1% of patients had persistent airflow limitation (FEV1 < 80%), 37.9% severe airway obstruction (FEV1 ≤ 60%), 33.6% required systemic corticosteroid maintenance therapy, 21.5% had salicylate intolerance and 43.2% rhinosinusitis. A Bayesian dependency network was calculated which revealed several interdependencies between the characteristics. E.g. there was a strong association between salicylate intolerance and rhinosinusitis, more patients received regular systemic corticosteroid treatment who had salicylate intolerance and the proportion of salicylate intolerance was significantly higher in females. Conclusion: The prevalence of SA was determined in Hungary which was lower than in other studies. Using a Bayesian-based network analysis several interdependencies were revealed between patient characteristics.

Effectiveness and safety of dupilumab for the treatment of severe asthma in a real-life French multi-centre adult cohort. Clin Exp Allergy 2020; 50:789-798. [PMID: 32469092 DOI: 10.1111/cea.13614] [Citation(s) in RCA: 72] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Revised: 04/22/2020] [Accepted: 04/29/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Dupilumab is a monoclonal anti-IL-4Rα antibody developed for the treatment of severe asthma (SA). An early access programme for dupilumab was opened in France in SA patients experiencing unacceptable steroids side-effects and/or life-threatening exacerbations. OBJECTIVE To assess changes in asthma control between baseline and 12 months of treatment. METHODS Multi-centre (n = 13) retrospective real-life cohort study. This study is registered on ClinicalTrials.gov (NCT04022447). RESULTS Overall, 64 patients with SA (median age 51, interquartile range [44-61]; 53% females) received dupilumab as add-on therapy to maximal standard of care; and 76% were on oral daily steroids at baseline. After 12 months, median asthma control test score improved from 14 [7-16] to 22 [17-24] (P < .001); median forced expiratory volume in 1 seconds increased from 58% [47-75] to 68% [58-88] (P = .001); and daily prednisone dose was reduced from 20 [10-30] to 5 [0-7] mg/d (P < .001). Annual exacerbations decreased from 4 [2-7] to 1 [0-2] (P < .001). Hypereosinophilia ≥1500/mm3 was observed at least once during follow-up in 16 patients (25%), persisting after 6 months in 8 (14%) of them. Increase in blood eosinophil count did not modify the clinical response during the study period. Injection-site reaction was the most common side effect (14%). Three deaths were observed, none related to treatment by investigators. CONCLUSION & CLINICAL RELEVANCE In this first real-life cohort study of predominantly steroid-dependent SA, dupilumab significantly improved asthma control and lung function and reduced oral steroids use and exacerbations rate. Despite limitations due to the retrospective study, these results are consistent with controlled trials efficacy data. Further studies are required to assess the clinical significance and long-term prognosis of sustained dupilumab-induced hypereosinophilia.

Abstract
Dupilumab, a fully human monoclonal antibody against interleukin-4 receptor α, is approved as add-on maintenance treatment for inadequately controlled type 2 severe asthma. This systematic review evaluated the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled severe asthma. PubMed, EMBASE and Cochrane Library were searched for RCTs and health economic evaluations. Critical and important asthma-related outcomes were evaluated. The risk of bias and the certainty of the evidence were assessed using GRADE. Three RCTs including 2735 subjects >12 years old and 24-52 weeks of follow-up were included. Dupilumab reduced with high certainty severe asthma exacerbations (Incidence rate ratio 0.51; 95% CI 0.45-0.59) and the percentage use of oral corticosteroid use (mean difference (MD) -28.2 mg/d; 95% CI -40.7 to -15.7). Asthma control (ACQ-5), quality of life (AQLQ) and rescue medication use [puffs/d] improved, without reaching the minimal important clinical difference: ACQ-5 MD -0.28 (95% CI -0.39 to -0.17); AQLQ MD +0.28 (95% CI 0.20-0.37); and rescue medication MD -0.35 (95% CI -0.73 to +0.02). FEV1 increased (MD +0.15; 95% CI +0.11 to +0.18) (moderate certainty). There was an increased rate of dupilumab-related adverse events (AEs) (moderate certainty) and of drug-related serious AEs (low certainty). The incremental cost-effectiveness ratio of dupilumab versus standard therapy was 464 000$/QALY (moderate certainty). More data on long-term safety are needed both for children and for adults, together with more efficacy data in the paediatric population.

Biologic and maintenance systemic corticosteroid therapy among US subspecialist-treated patients with severe asthma. Ann Allergy Asthma Immunol 2020; 125:294-303.e1. [PMID: 32304877 DOI: 10.1016/j.anai.2020.04.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 04/01/2020] [Accepted: 04/06/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Severe asthma (SA) often requires subspecialist management and treatment with biologic therapies or maintenance systemic corticosteroids (mSCS). OBJECTIVE To describe contemporary, real-world biologic and mSCS use among US subspecialist-treated patients with SA. METHODS CHRONICLE is an ongoing, noninterventional study of US adults with SA treated by allergists/immunologists or pulmonologists. Eligible patients are receiving biologics or mSCS or are uncontrolled on high-dosage inhaled corticosteroids with additional controllers. Biologic and mSCS use patterns and patient characteristics were summarized for patients enrolled between February 2018 and February 2019. RESULTS Among protocol-eligible patients, 58% and 12% were receiving biologics and mSCS, respectively, with 7% receiving both. Among 796 enrolled, most were women (67%), non-Hispanic white (71%), of suburban residence (50%), and had elevated body mass index (median: 31). Respiratory and nonrespiratory comorbidities were highly prevalent. With biologics (n = 557), 51% were anti-immunoglobulin E and 48% were anti-interleukin (IL)-5/IL-5Rα; from May 2018, 76% of initiations were anti-IL-5/IL-5Rα. In patients receiving mSCS, median prednisone-equivalent daily dose was 10 mg. Multivariate logistic regression found that patients of hospital clinics, sites with fewer nonphysician staff, and with a recorded concurrent chronic obstructive pulmonary disease diagnosis were less likely to receive biologics and more likely to receive mSCS. CONCLUSION In this real-world sample of US subspecialist-treated patients with SA not controlled by high-dosage inhaled corticosteroids with additional controllers, mSCS use was infrequent and biologic use was common, with similar prevalence of anti-immunoglobulin E and anti-IL-5/IL-5Rα biologics. Treatment differences associated with patient and site characteristics should be investigated to ensure equitable access to biologics and minimize mSCS use.

Abstract
BACKGROUND Clinical characteristics of the international population with severe asthma are unknown. Intercountry comparisons are hindered by variable data collection within regional and national severe asthma registries. We aimed to describe demographic and clinical characteristics of patients treated in severe asthma services in the United States, Europe, and the Asia-Pacific region. METHODS The International Severe Asthma Registry retrospectively and prospectively collected data in patients with severe asthma (≥ 18 years old), receiving Global Initiative for Asthma (GINA) Step 5 treatment or with severe asthma remaining uncontrolled at GINA Step 4. Baseline demographic and clinical data were collected from the United States, United Kingdom, South Korea, Italy, and the Severe Asthma Web-based Database registry (including Australia, Singapore, and New Zealand) from December 2014 to December 2017. RESULTS We included 4,990 patients. Mean (SD) age was 55.0 (15.9) years, and mean (SD) age at asthma onset was 30.7 (17.7) years. Patients were predominantly female (59.3%) and white (72.6%), had never smoked (60.5%), and were overweight or obese (70.4%); 34.9% were at GINA Step 5; and 57.2% had poorly controlled disease. A total of 51.1% of patients were receiving regular intermittent oral corticosteroids, and 25.4% were receiving biologics (72.6% for those at GINA Step 5). Mean (SD) exacerbation rate was 1.7 (2.7) per year. Intercountry variation was observed in clinical characteristics, prescribed treatments, and biomarker profiles. CONCLUSIONS Using a common data set and definitions, this study describes severe asthma characteristics of a large patient cohort included in multiple severe asthma registries and identifies country differences. Whether these are related to underlying epidemiological factors, environmental factors, phenotypes, asthma management systems, treatment access, and/or cultural factors requires further study.

Abstract
BACKGROUND Tools for quantification of asthma severity are limited. OBJECTIVE We sought to develop a continuous measure of asthma severity, the Asthma Severity Scoring System (ASSESS), for adolescents and adults, incorporating domains of asthma control, lung function, medications, and exacerbations. METHODS Baseline and 36-month longitudinal data from participants in phase 3 of the Severe Asthma Research Program (NCT01606826) were used. Scale properties, responsiveness, and a minimally important difference were determined. External replication was performed in participants enrolled in the Severe Asthma Research Program phase 1/2. The utility of ASSESS for detecting treatment response was explored in participants undergoing corticosteroid responsiveness testing with intramuscular triamcinolone and participants receiving biologics. RESULTS ASSESS scores ranged from 0 to 20 (8.78 ± 3.9; greater scores reflect worse severity) and differed among 5 phenotypic groups. Measurement properties were acceptable. ASSESS was responsive to changes in quality of life with a minimally important difference of 2, with good specificity for outcomes of asthma improvement and worsening but poor sensitivity. Replication analyses yielded similar results, with a 2-point decrease (improvement) associated with improvements in quality of life. Participants with a 2-point or greater decrease (improvement) in ASSESS scores also had greater improvement in lung function and asthma control after triamcinolone, but these differences were limited to phenotypic clusters 3, 4, and 5. Participants treated with biologics also had a 2-point or greater decrease (improvement) in ASSESS scores overall. CONCLUSIONS The ASSESS tool is an objective measure that might be useful in epidemiologic and clinical research studies for quantification of treatment response in individual patients and phenotypic groups. However, validation studies are warranted.
