Expert consensus on the use of systemic glucocorticoids for managing eosinophil-related diseases. Front Immunol 2024; 14:1310211. [PMID: 38250075 PMCID: PMC10796442 DOI: 10.3389/fimmu.2023.1310211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 12/11/2023] [Indexed: 01/23/2024] Open
Abstract
Eosinophil-related diseases represent a group of pathologic conditions with highly heterogeneous clinical presentation and symptoms ranging from mild to critical. Both systemic and localized forms of disease are typically treated with glucocorticoids. The approval of novel biologic therapies targeting the interleukin-5 pathway can help reduce the use of systemic glucocorticoids (SGC) in eosinophilic diseases and reduce the risk of SGC-related adverse effects (AEs). In this article, a panel of experts from different medical specialties reviewed current evidence on the use of SGC in two systemic eosinophilic diseases: Eosinophilic Granulomatosis with PolyAngiitis (EGPA) and HyperEosinophilic Syndrome (HES); and in two single-organ (respiratory) eosinophilic diseases: Chronic RhinoSinusitis with Nasal Polyps (CRSwNP) and Severe Asthma with Eosinophil Phenotype (SA-EP), and contrasted it with their experience in clinical practice. Using nominal group technique, they reached consensus on key aspects related to the dose and tapering of SGC as well as on the initiation of biologics as SGC-sparing agents. Early treatment with biologics could help prevent AEs associated with medium and long-term use of SGC.

Al-Ahmad M, Ali A, Maher A. Omalizumab Transitions in Severe Asthma: Factors Influencing Switching Decisions and Timing for Optimal Response. Med Princ Pract 2023; 32:323-331. [PMID: 37757780 PMCID: PMC10727686 DOI: 10.1159/000534319] [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: 05/18/2023] [Accepted: 09/25/2023] [Indexed: 09/29/2023] Open
Abstract
OBJECTIVE The objective of this study was to assess the effectiveness of switching from omalizumab to another biologic therapy for patients with severe asthma and evaluate factors that influenced the decision to switch and determined the optimal time for a good biologic response. SUBJECTS AND METHODS A retrospective study of severe asthma patients was conducted at Al-Rashed Allergy Center, a tertiary center in Kuwait. After meeting the eligibility criteria, patients were divided into two comparative groups: those continuing with omalizumab and those who started with omalizumab but switched to another biologic. RESULTS One hundred sixteen patients with severe asthma were recruited, and only 33 had access to multiple biological treatments. Approximately 22.4% switched from omalizumab. Male patients with a history of ischemic heart disease, chronic rhinosinusitis, and nasal polyps were more likely to switch if they had higher levels of eosinophils in the sputum. This study showed that every 1% increase in sputum eosinophils doubled the likelihood of a switch. Patients with access to alternative biological options had a much shorter mean duration of omalizumab therapy before switching compared to those with only affordable omalizumab: 4.9 ± 1.5 years versus 8.9 ± 1.3 years (p < 0.001). The optimal time to predict the likelihood of a good response was less than 5.5 years, with an area under the curve of 0.91 and p = 0.003. This cutoff point provided a sensitivity and specificity of approximately 89% and 100%, respectively. CONCLUSION An early transition from omalizumab, specifically within the first 5 years of treatment, in patients with severe asthma and higher sputum eosinophils may enhance the likelihood of a good response if other biological therapies were available.

Omalizumab for the treatment of patients with severe allergic asthma with immunoglobulin E levels above >1500 IU/mL. World Allergy Organ J 2023; 16:100787. [PMID: 37332525 PMCID: PMC10276275 DOI: 10.1016/j.waojou.2023.100787] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 04/24/2023] [Accepted: 05/16/2023] [Indexed: 06/20/2023] Open
Abstract
Immunoglobulin E (IgE) plays a critical role in the allergen-initiated inflammatory pathway and thus serves as a viable therapeutic target in allergic or IgE-mediated diseases such as asthma. Omalizumab, an anti-IgE biologic, has been approved in the United States (US, 2003) and in the European Union (EU, 2005) as an add-on therapy in patients with moderate-to-severe persistent asthma and severe allergic asthma (SAA) aged 6 years and older. The dose and frequency of omalizumab are adjusted based on the patient's body weight and baseline IgE levels, as recommended by its dosing tables. Currently, these dosing recommendations are limited to patients with baseline IgE levels of up to 1500 IU/mL in the European Union and 700 IU/mL in the United States. However, many patients with SAA have IgE levels >1500 IU/mL, highlighting an unmet need. This review presents the current evidence on the treatment benefits of omalizumab in patients with IgE levels >1500 IU/mL. The findings from the reviewed studies which included >3000 patients support the efficacy and effectiveness of omalizumab in reducing exacerbations, and improving asthma control, lung function, and quality of life in patients with severe asthma having IgE levels beyond the current dosing range. Omalizumab was well-tolerated in these patients, with no new safety signals. In addition, high IgE levels (>1500 IU/mL) are also reported in several comorbidities of asthma (allergic rhinitis, atopic dermatitis, allergic bronchopulmonary aspergillosis [ABPA], food allergy, and nasal polyposis) and omalizumab has demonstrated efficacy and safety in these indications. These data suggest that omalizumab may be considered for administration in SAA patients, with high IgE levels outside the current dosing tables. A detailed assessment of patients with high IgE levels is needed before deciding on the optimal treatment approach. A management algorithm for SAA patients with IgE >1500 IU/mL is proposed in this review and a suggestion to follow the Delphi consensus is advised.

Abstract
BACKGROUND AND PURPOSE Asthma is a heterogenous disease strongly associated with inflammation that has many different causes and triggers. Current asthma treatments target symptoms such as bronchoconstriction and airway inflammation. Despite recent advances in biological therapies, there remains a need for new classes of therapeutic agents with novel, upstream targets. The proteinase-activated receptor-2 (PAR2) has long been implicated in allergic airway inflammation and asthma and it remains an intriguing target for novel therapies. Here, we describe the actions of C781, a newly developed low MW PAR2 biased antagonist, in vitro and in vivo in the context of acute allergen exposure. EXPERIMENTAL APPROACH A human bronchial epithelial cell line expressing PAR2 (16HBE14o- cells) was used to evaluate the modulation in vitro, by C781, of physiological responses to PAR2 activation and downstream β-arrestin/MAPK and Gq/Ca2+ signalling. Acute Alternaria alternata sensitized and challenged mice were used to evaluate C781 as a prophylactically administered modulator of airway hyperresponsiveness, inflammation and mucus overproduction in vivo. KEY RESULTS C781 reduced in vitro physiological signalling in response to ligand and proteinase activation. C781 effectively antagonized β-arrestin/MAPK signalling without significant effect on Gq/Ca2+ signalling in vitro. Given prophylactically, C781 modulated airway hyperresponsiveness, airway inflammation and mucus overproduction of the small airways in an acute allergen-challenged mouse model. CONCLUSION AND IMPLICATIONS Our work demonstrates the first biased PAR2 antagonist for β-arrestin/MAPK signalling. C781 is efficacious as a prophylactic treatment for allergen-induced airway hyperresponsiveness and inflammation in mice. It exemplifies a key pharmacophore for PAR2 that can be optimized for clinical development.

Abstract
Allergic fungal rhinosinusitis (AFRS) is a noninvasive subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) that usually develops in immunocompetent atopic individuals and is more common in geographic regions characterized by warm temperatures and high humidity, conducive to higher environmental fungal presence. Allergic fungal rhinosinusitis usually presents with unique computed tomography findings and significant polyp burden, yet patients often report minimal sinus symptoms. Patients with AFRS often have extremely elevated serum total and fungal-specific IgE levels. Treatment almost always requires surgery, in which adjuvant medical therapy is critical to success. However, until recently the choice of adjuvant therapy has consisted primarily of either oral and/or topical steroids. Although oral corticosteroids decrease recurrence after surgery, data for the effectiveness of other adjunctive pharmacologic agents, including topical and oral antifungal agents and immunotherapy, have remained unclear and hence are not recommended in recent guidelines including the International Consensus of Allergy and Rhinology. Three biologics, omalizumab, dupilumab, and mepolizumab, have recently been approved for treating CRSwNP in general, but clinical trials to date with these biologics did not involve AFRS patients. Recently published case reports and smaller prospective studies have shown good efficacy of these biologics on the AFRS subgroup of patients. This article provides an overview of the understanding of the pathophysiology of AFRS, implications of this understanding on the possible role of biologics, and clinical reports on the use of biologics in treating AFRS. Because biologics are indicated for treating CRSwNP, follow up real-world evidence studies are needed for AFRS.

Can Leukotriene Receptor Antagonist Therapy Improve the Control of Patients with Severe Asthma on Biological Therapy and Coexisting Bronchiectasis? A Pilot Study. J Clin Med 2022; 11:jcm11164702. [PMID: 36012941 PMCID: PMC9410441 DOI: 10.3390/jcm11164702] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/03/2022] [Accepted: 08/10/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction: Asthma and bronchiectasis appear to be two related diseases and in their complex inflammatory interaction, the cysteinyl leukotriene/cysteinyl leukotriene receptor 1 (cysLT/cysLTR1) axis appears to play an important role given its involvement also in the neutrophilic pathway. To our knowledge, few studies have been conducted so far to evaluate the role of the leukotriene cysLT/cysLTr1 axis in the management of clinical and inflammatory outcomes within a population of patients with severe asthma and bronchiectasis. The aim of our study was to verify in this population the effect of leukotriene receptor antagonist (LTRA) therapy in clinical and inflammatory control before and after 6 months of introduction of biologic therapy. Methods: We retrospectively enrolled, from eight different severe asthma centers’ outpatients, 36 atopic patients with the simultaneous presence of non-cystic fibrosis (non-CF) and non-allergic bronchopulmonary aspergillosis (non-ABPA) bronchiectasis and severe asthma. The first biological injection was performed at baseline (T0 time). Patients who were already taking LTRA therapy at time T0 were recorded, and no new prescriptions were made. We observed our population over a 6-month period (T1 time). At the baseline we collected the following data: baseline characteristics, clinical history, high resolution computed tomography and bronchiectasis-related parameters and skin prick test. At both times T0 and T1 we collected the following data: asthma control test (ACT), asthma control questionnaire (ACQ), immunoglobulin E (IgE) level, blood count, fractional exhaled nitric oxide 50 (FeNO 50) and flow-volume spirometry. The study was retrospectively registered. Results: Our population had a mean age of 59.08 ± 11.09 and 50% were female. At T1, patients on LTRA therapy had a significantly lower FeNO value (33.03 ± 23.61 vs. 88.92 ± 77.96; p = 0.012). We assessed that the value of ΔFeNO (FeNO 50 T1 − FeNO 50 T0) and the number of unplanned specialist visits allowed a discrimination of 66.7% in the presence of LTRA therapy. We also verified how low FeNO values at time T1 were statistically significant predictors of LTRA therapy (ODD = 9.96 (0.94–0.99); p = 0.032). Conclusion: The presence of LTRA in therapy in a population of severe asthmatics with coexisting non-ASBPA bronchiectasis and non-cystic fibrosis, acting simultaneously on the T helper type 2 (TH2) pathway and probably on the neutrophilic component of bronchiectasis, would allow a further amplification of the beneficial effects of biological therapy, leading to a reduction in the number of unplanned visits to specialists.

Abstract
There are now several monoclonal antibody (mAb) therapies (“biologics”) available to treat severe asthma. Omalizumab is an anti-IgE mAb and is licensed in severe allergic asthma. Current evidence suggests it may decrease exacerbations by augmenting deficient antiviral immune responses in asthma. Like all other biologics, clinical efficacy is greatest in those with elevated T2 biomarkers. Three biologics target the interleukin (IL)-5–eosinophil pathway, including mepolizumab and reslizumab that target IL-5 itself, and benralizumab that targets the IL-5 receptor (IL-5R-α). These drugs all reduce the exacerbation rate in those with raised blood eosinophil counts. Mepolizumab and benralizumab have also demonstrated steroid-sparing efficacy. Reslizumab is the only biologic that is given intravenously rather than by the subcutaneous route. Dupilumab targets the IL-4 receptor and like mepolizumab and benralizumab is effective at reducing exacerbation rate as well as oral corticosteroid requirements. It is also effective for the treatment of nasal polyposis and atopic dermatitis. Tezepelumab is an anti-TSLP (thymic stromal lymphopoietin) mAb that has recently completed phase 3 trials demonstrating significant reductions in exacerbation rate even at lower T2 biomarker thresholds.Many patients with severe asthma qualify for more than one biologic. To date, there are no head-to-head trials to aid physicians in this choice. However, post-hoc analyses have identified certain clinical characteristics that are associated with superior responses to some therapies. The presence of allergic and/or eosinophilic comorbidities, such as atopic dermatitis, nasal polyposis or eosinophilic granulomatosis with polyangiitis, that may additionally benefit by the choice of biologic should also be taken into consideration, as should patient preferences which may include dosing frequency. To date, all biologics have been shown to have excellent safety profiles.

Abstract
Mast cells are tissue-resident immune cells that function in both innate and adaptive immunity through the release of both preformed granule-stored mediators, and newly generated proinflammatory mediators that contribute to the generation of both the early and late phases of the allergic inflammatory response. Although mast cells can be activated by a vast array of mediators to contribute to homeostasis and pathophysiology in diverse settings and contexts, in this review, we will focus on the canonical setting of IgE-mediated activation and allergic inflammation. IgE-dependent activation of mast cells occurs through the high affinity IgE receptor, FcεRI, which is a multimeric receptor complex that, once crosslinked by antigen, triggers a cascade of signaling to generate a robust response in mast cells. Here, we discuss FcεRI structure and function, and describe established and emerging roles of the β subunit of FcεRI (FcεRIβ) in regulating mast cell function and FcεRI trafficking and signaling. We discuss current approaches to target IgE and FcεRI signaling and emerging approaches that could target FcεRIβ specifically. We examine how alternative splicing of FcεRIβ alters protein function and how manipulation of splicing could be employed as a therapeutic approach. Targeting FcεRI directly and/or IgE binding to FcεRI are promising approaches to therapeutics for allergic inflammation. The characteristic role of FcεRIβ in both trafficking and signaling of the FcεRI receptor complex, the specificity to IgE-mediated activation pathways, and the preferential expression in mast cells and basophils, makes FcεRIβ an excellent, but challenging, candidate for therapeutic strategies in allergy and asthma, if targeting can be realized.

Abstract
Immune responses that result in asthma exacerbation are associated with allergen or viral exposure. Identification of common immune factors will be beneficial for the development of uniformed targeted therapy. We employed a House Dust Mite (HDM) mouse model of asthma and challenged allergic HDM mice with allergens (HDM, cockroach extract (CRE)) or respiratory syncytial virus (RSV). Purified lung immune cells underwent high-dimensional single-cell RNA deep sequencing (scRNA-seq) to generate an RNA transcriptome. Gene silencing with siRNA was employed to confirm the efficacy of scRNA-seq analysis. scRNA-seq UMAP analysis portrayed an array of cell markers within individual immune clusters. SCENIC R analysis showed an increase in regulon number and activity in CD11b- DC cells. Analysis of conserved regulon factors further identified Creb5 as a shared regulon between the exacerbation groups. Creb5 siRNAs attenuated HDM, CRE or RSV-induced asthma exacerbation. scRNA-seq multidimensional analysis of immune clusters identified gene pathways that were conserved between the exacerbation groups. We propose that these analyses provide a strong framework that could be used to identify specific therapeutic targets in multifaceted pathologies.

Abstract
Asthma is a multifactorial inflammatory disorder of the respiratory system characterized by high diversity in clinical manifestations, underlying pathological mechanisms and response to treatment. It is generally established that human microbiota plays an essential role in shaping a healthy immune response, while its perturbation can cause chronic inflammation related to a wide range of diseases, including asthma. Systems biology approaches encompassing microbiome analysis can offer valuable platforms towards a global understanding of asthma complexity and improving patients' classification, status monitoring and therapeutic choices. In the present review, we summarize recent studies exploring the contribution of microbiota dysbiosis to asthma pathogenesis and heterogeneity in the context of asthma phenotypes-endotypes and administered medication. We subsequently focus on emerging efforts to gain deeper insights into microbiota-host interactions driving asthma complexity by integrating microbiome and host multi-omics data. One of the most prominent achievements of these research efforts is the association of refractory neutrophilic asthma with certain microbial signatures, including predominant pathogenic bacterial taxa (such as Proteobacteria phyla, Gammaproteobacteria class, especially species from Haemophilus and Moraxella genera). Overall, despite existing challenges, large-scale multi-omics endeavors may provide promising biomarkers and therapeutic targets for future development of novel microbe-based personalized strategies for diagnosis, prevention and/or treatment of uncontrollable asthma.

Expert Rev Clin Immunol 2021; 17:1283-1299. [PMID: 34761712 DOI: 10.1080/1744666x.2021.2004123] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/29/2022]
Abstract
INTRODUCTION Based on the latest literature evidence, between 30% and 60% of adults with severe refractory asthma (SRA) are systemic corticosteroid (SCS) dependent. There are numerous therapeutic options in asthma, which are often not effective in severe forms. In these cases, SCS should be considered, but it is increasingly recognized that their regular use is often associated with significant and potentially serious adverse events. AREAS COVERED The aim of this article is to provide an update about the recent and significant literature on SCS and to establish their role in the management of SRA. We summarized the most important and recent evidence and we provided useful indications for clinicians. EXPERT OPINION There is now strong evidence supporting the increased risk of comorbidities and complications with long-term SCS therapies, regardless of the dose. New evidence on SCS tapering and withdrawal will allow to define protocols to address SCS management with greater safety and effectiveness, after starting efficient steroid-sparing strategies. In the next 5years, it will be necessary to implement corrective actions to address these unmet needs, to reduce the inappropriate use of SCS by maximizing the application of more innovative and effective therapies.

Effect of omalizumab as add-on therapy to Quality of Life Questionnaire for Korean Asthmatics (KAQLQ) in Korean patients with severe persistent allergic asthma. Korean J Intern Med 2021; 36:1001-1013. [PMID: 34237826 PMCID: PMC8273830 DOI: 10.3904/kjim.2020.549] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 11/16/2020] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND/AIMS Omalizumab is the first biologic known to be effective in patients with severe allergic asthma. METHODS This study was conducted as a multicenter, single-group, open trial to evaluate the improvement in the quality of life with the additional administration of omalizumab for 24 weeks in Korean patients with severe persistent allergic asthma. RESULTS Of the 44 patients, 31.8% were men and the mean age was 49.8 ± 11.8 years. A score improvement of 0.5 points or more in the Quality of Life Questionnaire for Korean Asthmatics (KAQLQ) was noted in 50.0% (22/44) of the patinets. In the improved group, the baseline total immunoglobulin E (IgE) level and the amount of omalizumab used were higher, and the day and night asthma symptoms were more severe, compared to those in the non-improved group. According to the Global Evaluation of Treatment Effectiveness, favorable outcomes were found in 78.6% of patients. The Korean asthma control test (p < 0.005) and forced expiratory volume in 1 second % predicted (FEV1%; p < 0.01) improved significantly in patients who received omalizumab treatment, compared to that at week 0, and the total dose of rescue systemic corticosteroids significantly decreased (p < 0.05). The improved group on KAQLQ showed a significant improvement in FEV1% (p < 0.001). CONCLUSION Omalizumab can be considered a biological treatment for Korean patients with severe allergic asthma. It is recommended to consider omalizumab as add-on therapy in patients with high baseline total IgE levels and severe asthma symptoms.

Abstract
BACKGROUND Severe asthma commonly affects 5-10% of the asthmatic population and accounts for approximately 50% of the overall asthma costs. OBJECTIVE This analysis investigated how severe asthma is diagnosed, treated, and managed by specialists and general practitioners (GPs) in Switzerland. METHODS Two surveys, one each among specialists (N = 44) and GPs (N = 153), were conducted to understand their self-perception on diagnosis, treatment, and management of severe asthma. RESULTS Fifty-five percent of the specialists felt very confident and 43% confident in recognizing the symptoms of severe asthma and diagnosing severe asthma. In contrast, 9% of the GPs were very confident and 59% confident in diagnosing severe asthma. More specific diagnostic tests for severe asthma, like total and specific immunoglobulin E levels and measurement of the fraction of exhaled nitric oxide, were run by specialists (χ2 = 171.4; df = 15, p < 0.001). GPs and specialists were using different measurements to assess severe asthma (χ2 = 385.2; df = 13, p < 0.001) and their prescribing patterns differed significantly (χ2 = 189.8; df = 10, p < 0.001). GPs referred patients with severe asthma if the diagnosis was unclear (24%), if treatment failure occurred (26%), and if the patients were at high risk (41%). CONCLUSIONS Oral corticosteroids (OCSs) are considered as background therapy for severe asthma by GPs and specialists. In order to reduce the OCS burden, there is a need to improve the awareness for other add-on therapies. A joint collaboration between GPs and specialists is the key to leverage therapeutic strategies together.

Interferon characterization associates with asthma and is a potential biomarker of predictive diagnosis. Biosci Rep 2021; 41:228038.

Abstract
Interferon (IFN) plays a role in immune and inflammation responses. However, the effect of IFN in asthma is still not fully clear. The present study was conducted to better understand the role of IFN signatures in asthma. Blood samples from case–control studies (study 1: 348 asthmas and 39 normal controls and validation study 2: 411 asthmas and 87 normal controls) were enrolled. The single-sample gene set enrichment analysis (ssGSEA) method was used to quantify the levels of 74 IFN signatures. Gene Ontology analysis and pathway function analysis were performed for functional analysis and a protein–protein interaction (PPI) network was constructed. The area under the curve (AUC) value was used to evaluate the diagnostic ability. In our work, IFN-γ response-DN, negative regulation of IFN-γ secretion, IFNG pathway, negative regulation of response to IFN-γ, and type 1 IFN biosynthetic process showed higher levels in asthma. Functional analysis demonstrated that pathway and biological process involved in IFN signaling pathway, regulation of type 1 IFN production and response to IFN-γ. Hub IFN-related genes were identified, and their combination as biomarker exhibited a good diagnostic capacity for asthma (AUC = 0.832). These findings offered more insight into the underlying mechanism of how IFN signatures affected asthma. The use of the easy-to-apply IFN-related genes might serve as a promising blood-based biomarker for early diagnosis of asthma.

Abstract
BACKGROUND Regular treatment of patients with asthma with oral corticosteroids (OCS) remains common despite potential severe side effects and alternative treatment options. However, there is limited data on the prevalence of OCS prescriptions for patients with asthma in Germany. METHODS Records from 1039 General practitioners for the years 2015-2017 in the German IMS® Disease Analyzer database were retrospectively analysed for patients with at least two confirmed asthma diagnoses (ICD-10) per observed year, representing approximately 30,000 patients per year. Asthma treatment steps (1-5) were assigned according to the German national guideline, based on prescribed therapies. RESULTS In the years 2015-2017, 20.3-21.3% of patients were classified as being in treatment step 1, 4.7-5.2% in step 2, 38.8-40.1% in step 3, 31.7-32.1% in step 4 and 2.7-3.2% in step 5. Proportions of patients treated with OCS >30 days/year were 9.4% (2015), 9.6% (2016) and 8.9% (2017), reducing to 8.1%, 8.2% and 7.4%, respectively, when patients with other inflammatory diseases possibly requiring OCS treatment were excluded. Use of OCS >30 days/year was more prevalent in patients aged >65 years (14.1-15.0%) than those aged 18-65 years (6.8-7.8%). Median daily prednisolone dose was 10-15 mg/day. Approximately 30% of patients treated with OCS >30 days/year were not in step 5 (based on their prescribed inhaled therapies). CONCLUSION These data suggest that a substantial proportion of patients with asthma in non-specialised care in Germany receive OCS prescriptions regularly, despite the availability of less harmful alternative treatment options.

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
Severe refractory asthma (SRA) still has a high economic and social impact, including a reduction in quality of life (QoL), productivity, a greater risk of exacerbations and emergency department (ED) visits. Another major issue is the need of oral corticosteroids (OCS), often due to a poor response to standard therapies or the lack of indication for currently available biological drugs. A thorough understanding of the immunological pathways and eosinophilopoietic processes allows a correct application of the new pharmacological strategies and leads to better clinical responses. For these unmet needs, several monoclonal antibody (mAb) drugs have been introduced over the past few years. These are mainly available for allergic and especially eosinophilic uncontrolled refractory asthma. As the number of therapeutic options increases, the choice of biological drugs can be made only after careful considerations of the particular asthma endotype, patients’ comorbidities and clinical data. The selection of the correct therapeutic option can therefore be guided after a careful evaluation of the particular endotype and phenotype, from the combined evaluation of inflammatory biomarkers, clinical picture and comorbidities. The careful evaluation of all these parameters can therefore help the physician in the optimal management of these complex patients, for whom it is often possible to achieve exceptional results by managing the available options in the best possible way. The aim of this review is to define the positioning of the biological drugs currently available for type 2 asthma, with a special focus on options for eosinophilic asthma in the context of the most recent knowledge of immunological pathways.

Abstract
There is an ongoing debate about the benefit-risk balance of systemic corticosteroids (SCS) in asthma treatment. We investigated the associations between SCS use and disease burden in a database cohort of asthmatics, categorized into SCS and non-SCS prescription at baseline and quartiles (Q) by cumulative SCS dosage. Of the 10,579 patients, the SCS cohort comprised 3103 patients (29.3%). Mean SCS dosages at baseline were 0.08, 0.29, 0.79, and 4.58 mg/day in Q1, Q2, Q3, and Q4, respectively. Similar SCS dosages were used within each quartile throughout the study period. No remarkable changes in asthma severity or control status were observed. All SCS cohorts had a higher risk of intermittent SCS exposure during the observation period. SCS use was associated with osteoporosis, diabetes, anxiety/neurosis, and depression. SCS-dependent treatment does not necessarily lead to the future improvement of asthma control; rather, it may negatively impact systemic health, even at mean dosages <5 mg/day.

Abstract
PURPOSE OF REVIEW Asthma is a heterogenous disease associated with different phenotypes and endotypes. The unmet needs with severe asthma have led to the emergence of potential therapeutic targets beyond the existing therapies. Recently, several biologics were examined and some have now been approved to target T2 airway inflammation in patients with severe disease. We provide an overview of recently approved biologic, those which are emerging and highlight unmet needs in this area. RECENT FINDINGS Multiple biologics targeting T2 high asthma are now available for clinical use in the appropriate groups of severe asthma. These target overlapping phenotypes, which include allergic and eosinophilic asthma. Available biologics were shown to improve outcomes that include the reduction of exacerbations and improvement of lung function. Some have also demonstrated improvement in patient-reported outcomes. Some of these biologics have also demonstrated beneficial effects on associated asthma comorbidities. Biomarkers help predict response to certain biologics, although only few currently exist. Emerging biologics blocking other pathways of airway inflammation are under development. Several small molecule antagonists and inhibitors are also in development. Biologics and therapies targeting T2 low or non-T2 asthma are needed. SUMMARY Recently approved biologic therapies improve asthma outcomes in subset of patients. Future research to uncover better predictors of response can improve the precise approach to therapy of patients with severe disease.

Abstract
Asthma is a chronic inflammatory disease of the airways affecting more than 300 million patients worldwide. The disease can be of various severity ranging from very mild to severe. The severe form of the disease only affects about 5% of patients but is responsible for a large component of the overall disease burden and results in about half of direct asthma-related costs. This led to important investments in research, which allowed better understanding of its pathophysiology and the development of new therapeutic strategies. Despite those breakthroughs, recent guidelines still emphasize the need to distinguish uncontrolled or difficult-to-control asthma from severe asthma. Indeed, a significant number of patients referred to severe asthma clinics are non-severe uncontrolled patients. However, the basics of asthma management such as ensuring that the patient has the right diagnosis, recognition of contributing comorbidities, avoidance of exposure to sensitizing agents in allergic individuals, regular assessment of control, and patient education should not be forgotten. The major improvements in pathophysiology arose from the evidences that asthma is of heterogeneous nature. Such heterogeneity has been particularly studied in severe asthma, leading to the recognition of more homogeneous groups referred to as phenotypes. Appropriate phenotyping of individual patients allows enforcing more specific treatment plans for patients, which is a step toward precision medicine. The high morbidity and socioeconomic burden of severe asthma has led to the development of optimized therapeutic strategies in addition to the commercialization of new drugs. Many of these have targeted the eosinophilic component of inflammatory asthma phenotypes while there is still a need to develop new therapies for non-eosinophilic asthma. When asthma is not controlled by optimal therapy, including a high-dose of inhaled corticosteroid (ICS) and a long-acting beta-agonist (LABA), a long acting anticholinergic agent can be added and if insufficient, a variety of biologic agents is now available in many countries. When biologics are not an option, thermoplasty and macrolides have also become available. Despite many recent breakthroughs in severe asthma, much research needs to be done. Improvement in availability of targeted asthma medications and asthma prevention should be top priorities.

Abstract
BACKGROUND ARIETTA was a prospective, single-arm, noninterventional, multicenter study in patients with severe asthma. OBJECTIVE To examine the predictive and prognostic abilities of type 2 biomarkers for severe asthma outcomes. METHODS Adult patients with severe asthma receiving daily inhaled corticosteroids (fluticasone propionate ≥500 μg or equivalent) and ≥1 second controller medication were enrolled. Biomarker, clinical, and safety data were collected over 52 weeks. The primary endpoint was the asthma exacerbation rate over 52 weeks in serum periostin-high (≥50 ng/mL at baseline) versus periostin-low subgroups (<50 ng/mL). Correlations between biomarker levels (periostin, blood eosinophils, IgE, and fractional exhaled nitric oxide [FeNO]) and between central and local laboratory measurements (blood eosinophils and IgE) were assessed. The study was terminated before planned enrollment was completed. RESULTS Of 465 patients, 66.5% were female, 13.3% were receiving oral corticosteroids, 42.4% had ≥1 exacerbation in the previous year, 52.0% were periostin-high, and 87.5% had type 2 inflammation (blood eosinophils ≥150 cells/μL and/or FeNO ≥25 ppb and/or positive skin allergen test). Biomarker levels correlated poorly with each other. Central and local laboratory blood eosinophil and IgE measurements generally agreed. No difference was observed in exacerbation rates over 52 weeks between periostin-high and periostin-low patients (rate ratio, 0.93; 95% confidence interval, 0.67-1.28; P = .642). Results suggested higher exacerbation rates in patients with blood eosinophils ≥300 cells/μL and FeNO ≥25 ppb. CONCLUSIONS No prognostic value for serum periostin related to exacerbations was detected. Higher blood eosinophils combined with increased FeNO were potentially associated with increased exacerbation rates.

Abstract
Introduction Inadequately controlled severe asthma patients require additional therapy accounting for significant clinical and economic burden. Our analysis aims to determine the cost-effectiveness of omalizumab in the management of severe allergic asthma in Italy based on observational data from the PROXIMA study. Methods Observational data on efficacy, healthcare resource utilization and changes in quality of life at 12 months after the initiation of omalizumab were examined to estimate the cost-effectiveness compared to pre-omalizumab period and results were expressed with Incremental Cost-Effectiveness Ratio (ICER). The cost–utility analysis estimated the cost per quality-adjusted life-year (QALY) gained. Direct health costs were assessed from the perspective of the Italian National Health Service (NHS). Results Omalizumab reduced the incidence of exacerbations, number of hospitalizations, physician visits, and improved quality of life after 12 months of treatment. Omalizumab had a greater effectiveness than pre-omalizumab treatment involving 0.132 QALYs gained and led to a €3729 per patient reduction in direct healthcare costs, excluding the add-on treatment cost. Nevertheless, the addition of omalizumab cost led to €7478 increase in total direct costs with respect to pre-omalizumab period. Based on difference in total direct cost and difference in QALY between post and pre-omalizumab period, the ICER was €56,847. According to sensitivity analysis, omalizumab provided a cost-effective use of NHS resources, already at 20% discounted price. Conclusion This study offers a real-world evidence of omalizumab effectiveness in Italy. Despite the high acquisition cost of the innovative drug, omalizumab is a sustainable treatment option for patients with uncontrolled severe allergic asthma.

Abstract
Improved understanding of the contribution of immune-inflammatory mechanisms in allergic diseases and asthma has encouraged development of biologicals and small molecules specifically targeting the innate and adaptive immune response. There are several critical points impacting the efficacy of this stratified approach, from the complexity of disease endotypes to the effectiveness in real-world settings. We discuss here how these barriers can be overcome to facilitate the development of implementation science for allergic diseases and asthma.

Abstract
Globally, chronic respiratory diseases (CRDs), both communicable and noncommunicable, are among the leading causes of mortality, morbidity, economic and societal burden, and disability-adjusted life years (DALYs). CRDs affect multiple components of respiratory system, including the airways, parenchyma, and pulmonary vasculature. Although noncommunicable respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), cystic fibrosis (CF), and lung cancer (LC), account for enormous disease burden, the currently available therapies only focus on alleviating the symptoms of diseases rather than providing optimal treatment and/or prevention. Similarly a major respiratory communicable disease, that is, tuberculosis (TB), is associated with the challenge of increasingly developing antibiotic resistance in the bacterial pathogen Mycobacterium tuberculosis. In light of these challenges, we aim to summarize the underlying molecular and cellular mechanisms that lead to hallmark pathophysiology of CRDs. Moreover, we will also highlight the limitations of current therapeutic strategies and explore novel drug delivery options that may be potentially more effective in the management of CRDs.

Abstract
BACKGROUND Asthma is a complex disease associated with many factors such as immunologic, environmental, genetic, and other factors. Common medicines used to treat asthma include β-agonist and glucocorticoid. However, in the long-term treatment, the effect of the above-mentioned drugs is not satisfactory, so many patients choose oral Chinese medicines instead of western medicines. The introduction of Chinese medicines therapies, a rapid proliferation of the literature on management of asthma in general, call for novel ways of evidence synthesis in this area. This systematic review is to systematically summarize and evaluate a large number of evidences for Chinese herbal interventions for asthma. Evaluate the efficacy and safety of Chinese medicines in the treatment of asthma and inform a decision aid for the clinical encounter between patients and clinicians. In addition, it helps to establish a future research agenda. METHODS Five English databases (PubMed, Web of science, EBASE, Springer Cochrane Library, and WHO International Clinical Trials Registry Platform) and 4 Chinese databases (Wanfang Database, Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, and Chinese Biomedical Literature Database) will be searched normatively according to the rule of each database from the inception to the present. The literature screening, data extraction, and quality assessment will be conducted by 2 researchers independently. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. Asthma control test symptom score will be assessed as the primary outcome. The curative effect of single symptom and sign; Withdrawal and reduction of western medicines in a course of treatment, including: time, type, and quantity; Maintenance of western medicines after the course of treatment, including: type, quantity; Asthma Quality of Life Questionnaire; laboratory efficacy indexes as the secondary outcome. General physical examination; routine examination of blood, urine, and stool; electrocardiogram; liver and kidney function examination; possible adverse reactions and related detection indicators as the security indexes. Meta-analysis will be performed using RevMan5.3.5 software provided by the Cochrane Collaboration. RESULTS This study will provide high-quality synthesis based on current evidence of Chinese medicines treatment for asthma in several aspects, including asthma control score, side effects and laboratory examination such as lung-function test, serum total immunoglobulin, and so on. CONCLUSION The results of this study will provide updated evidence for whether Chinese medicines is an effective and safe intervention for asthma.
