The objective of this study was to assess NP and asthma outcomes in benralizumab-treated patients with SEA and comorbid NP in a real-world setting.Patients and Methods: RANS was a retrospective, multi-country observational study (ClinicalTrials.gov: NCT05180357) using medical chart reviews of adults with SEA and comorbid NP. Total NP Score (NPS), SinoNasal Outcome Test-22 (SNOT-22) total score, annualized exacerbation rate (AER), and 6-item Asthma Control Questionnaire (ACQ-6) and Asthma Control Test (ACT) scores during the 12 months pre-index (baseline) and post-index (follow-up) were measured. Clinically meaningful improvement from baseline following treatment, in terms of total NPS (≥ 1-point reduction), SNOT-22 total (≥ 8.9-point reduction), ACQ-6 (≥ 0.5-point reduction) or ACT (≥ 3-point increase) scores, were reported.Results: A total of 233 patients were included. Baseline mean (standard deviation [SD]) NPS and SNOT-22 total scores were 3.8 (2.4) and 47.5 (22.6), respectively. The mean change (95% confidence interval [CI]) from baseline was – 1.2 (– 1.7, – 0.6) for NPS, and – 19.8 (– 23.6, – 15.9) for SNOT-22. The AER (95% CI) was 1.2 (0.96, 1.41) at baseline and 0.2 (0.13, 0.28) at follow-up. Mean (SD) ACQ-6 and ACT scores were 1.6 (1.3) and 15.0 (5.2) at baseline and 0.8 (1.0) and 22.0 (3.9) at follow-up, respectively. The proportion of patients who achieved clinically meaningful improvements in NPS, SNOT-22 total, ACQ-6, and ACT scores was 49.1%, 67.6%, 56.6%, and 81.1%, respectively.Conclusion: In this real-world study, improvements in NP and asthma outcomes in patients with SEA and comorbid NP were observed during the 12 months following benralizumab initiation.Keywords: exacerbations, comorbidity, biologics, patient-reported outcomes, SinoNasal Outcome Test-22, Nasal Polyps Score

The latter are driven by molecular interactions, mediated by intercellular networks. With regard to the biological treatments of either allergic or non-allergic eosinophilic type 2 asthma, real-world studies have confirmed the positive effects of currently available antibodies directed against immunoglobulins E (IgE), interleukin-5 (IL-5) and its receptor, as well as the receptors of interleukins-4 (IL-4) and 13 (IL-13). The best way to treat severe asthma should be chosen based on the peculiar phenotypic and endotypic traits of each patient. This will lead to relevant improvements in both clinical and functional outcomes. In particular, biological therapies can change the lives of asthma patients with a strong impact on quality of life. Unfortunately, patients with severe non-type-2 asthma, who continue to have pertinent unmet needs, are not receiving satisfactory advances within the context of biological treatments. It is also hopeful that in the next future new therapeutic strategies will be specifically implemented for these people, perhaps offering them the opportunity to improve their current, mostly inadequate asthma management.Keywords: type 2 severe asthma, monoclonal antibodies, pro-inflammatory cytokines, quality of life

Here, we outline the characteristics and long-term clinical outcomes in naïve-to-biologics and biologics-experienced patients treated with benralizumab for up to 96 weeks. Bio-experienced patients were split into omalizumab and mepolizumab subsets according to the type of biologic previously used.Results: A total of 124 (76.5%) naïve and 38 (23.5%) bio-experienced patients were evaluated at index date; 13 patients (34.2%) switched from mepolizumab, 21 patients (55.3%) switched from omalizumab, and four patients (10.5%) received both biologics. The mepolizumab subset was characterized by the longest SEA duration (median of 4.6 years), the highest prevalence of chronic rhinosinusitis with nasal polyposis (CRSwNP) (76.5%), and the greatest oral corticosteroid (OCS) daily dosage (median of 25 mg prednisone equivalent). The omalizumab group showed the highest severe annual exacerbation rate (AER) (1.70). At 96 weeks, treatment with benralizumab reduced any and severe AER by more than 87% and 94%, respectively, across all groups. Lung function was overall preserved, with major improvements observed in the mepolizumab group, which also revealed a 100% drop of the median OCS dose. Asthma Control Test (ACT) score improved in the naïve group while its increment was more variable in bio-experienced patients; among these, a marked difference was noticed between omalizumab and mepolizumab subsets (median ACT score of 23.5 and 18, respectively).Conclusion: Benralizumab promotes durable and profound clinical benefits in naïve and bio-experienced groups, indicating that a nearly complete depletion of eosinophils is highly beneficial in the control of SEA, independently of previous biologic use.Keywords: benralizumab, asthma, eosinophils, switch, long-term

Patients were classified according to airflow obstruction, GOLD risk categories, and divided in 4 groups: A = no exacerbations; B = 1 moderate exacerbation; C = 1 severe exacerbation; D = ≥ 2 moderate and/or severe exacerbations. Overall all-cause mortality stratified by age, COPD category, and COPD therapy. A logistic regression model assessed the association of clinical characteristics with mortality.Results: 1111 patients were included (73% males), of which 41.5% had a history of exacerbations. As expected, the proportion of patients experiencing ≥ 1 exacerbation during follow-up increased according to pre-defined study risk categories (B: 79%, C: 84%, D: 97.4%). Overall, by the end of follow-up, 45.5% of patients without a history of exacerbation experienced an exacerbation (31% of which severe), and 13% died. Deceased patients were significantly older, more obstructed and hyperinflated, and more frequently active smokers compared with survivors. Severe exacerbations were more frequent in patients that died (23.5%, vs 10.2%; p-value: 0.002). Chronic heart failure and ischemic heart disease were the only comorbidities associated with a higher odds ratio (OR) for death (OR: 2.2, p-value: 0.001; and OR: 1.9, p-value: 0.007). Treatment patterns were similar in patients that died and survivors.Conclusion: Patients with a low exacerbation risk are exposed to a significant future risk of moderate/severe exacerbations. Real life data confirm the strong association between mortality and cardiovascular comorbidities in COPD.Keywords: pulmonary disease chronic obstructive, heart failure, ischaemic heart disease, respiratory medicine, public health

Functional and clinical parameters were assessed at baseline, and after 52 weeks of treatment with this combined double inhaled therapy.Results: We enrolled 110 subjects suffering from COPD. A 12-month UMEC/VI treatment induced significant improvements in total lung capacity (TLC) (p < 0.05), and residual volume (RV) (p < 0.0001). Pulmonary deflation was paralleled by significant increases of forced expiratory volume in one second (FEV1) (p < 0.0001), forced vital capacity (FVC) (p < 0.01), forced expiratory flow between 25% and 75% of FVC (FEF25– 75) (p < 0.0001) and diffusion capacity of the lung (DLCOcSB) (p < 0.05). In addition, in the same period, we also observed significant reductions of airway resistance including total resistance (Rtot) (p < 0.0001) and specific effective resistance (sReff) (p < 0.0001). Other improvements were detected with regard to modified British Medical Research Council (mMRC) questionnaire score (p < 0.0001), COPD Assessment Test (CAT) score (p < 0.0001), and COPD exacerbation rate (p < 0.0001). In particular, the reported changes of mMRC/CAT scores and COPD exacerbation numbers were significantly correlated with UMEC/VI–induced modifications of TLC, RV, FVC and FEV1.Conclusion: In conclusion, our study corroborates in a real-life context the effectiveness of UMEC/VI in COPD treatment. Indeed, our broad investigational strategy has allowed to better characterize the functional mechanisms underpinning the therapeutic properties of UMEC/VI association.Keywords: COPD, dual inhaled therapy, lung function, airway resistance, exacerbations

Patients included in real-world studies are often characterized by high mean/median BEC, while patients with BEC close to 300 cells/mm3 are poorly represented. This post hoc analysis from the Italian study ANANKE aims to define the clinical features and corroborate the efficacy of benralizumab in real world in the BEC 300– 450 cells/mm3 subset of patients.Patients and Methods: Post hoc analysis of the Italian, multicenter, observational, retrospective real-life study ANANKE (NCT04272463). Baseline clinical and laboratory characteristics were collected in the 12 months prior to benralizumab treatment and presented for a BEC 300– 450 cells/mm3 subgroup of patients. Change over time of BEC, annualized exacerbation rate (AER), asthma control (ACT), lung function and oral corticosteroid (OCS) use at 16, 24 and 48 weeks after benralizumab introduction were collected.Results: A total of 164 patients were analyzed, 34 of whom with a BEC of 300– 450 cells/mm3. This subgroup was more likely to be female (64.7%), with lower rates of severe exacerbations at baseline when compared to the total population (0.69 vs 1.01). After 48 weeks of benralizumab treatment, the BEC 300– 450 subset showed similar reductions in AER (− 94.8% vs − 92.2%) and OCS use (median dose reduction of 100% in both groups), as well as improvement in ACT score (median scores 22.5 vs 22) and lung function (pre-BD FEV1: +200 mL vs +300 mL) when compared to the total population. No discontinuations for safety reasons were registered.Conclusion: At baseline, apart from lower severe exacerbation rate, the BEC 300– 450 cells/mm3 subset of patients is comparable to the total population prescribed with benralizumab. In this real-life study, benralizumab is as effective in BEC 300– 450 patients as in the total population.Keywords: severe eosinophilic asthma, blood eosinophil count, benralizumab, observational, real-world evidence, real-life

With regard to the latter diseases, few real-life clinical investigations have been carried out to date.Objective: The primary end point of this single-center observational study was to evaluate in a real-life setting the short-term therapeutic effects of dupilumab in patients with severe asthma and nasal polyposis.Methods: At baseline and after 4 weeks of add-on therapy with dupilumab, several clinical and functional parameters were assessed in 20 patients with severe asthma and nasal polyposis, including both allergic and nonallergic subjects.Results: After 4 weeks of treatment with dupilumab, all patients experienced remarkable improvement in both severe asthma and nasal polyposis. In particular, asthma-control test and sinonasal outcome test 22 scores had significantly increased (p< 0.0001) and decreased (p< 0.0001), respectively. Oral corticosteroid intake got to zero within 4 weeks (p< 0.0001). Moreover, in week 4, significant increases were detected with regard to both prebronchodilator forced expiratory volume in the first second (p< 0.01) and forced vital capacity (FVC; p< 0.05). At the same time point, dupilumab had significantly reduced residual volume (p< 0.0001) and total lung capacity (p< 0.001), whereas it had enhanced forced midexpiratory flow of 25%– 75% FVC (p< 0.01) and peak expiratory flow (p< 0.01). After 4 weeks of treatment, dupilumab had also lowered levels of fractional exhaled nitric oxide (p< 0.0001).Conclusion: The results of this real-life study suggest that dupilumab can be utilized in both allergic and nonallergic patients with severe asthma and nasal polyposis as a valuable add-on biological therapy with rapid onset of action.Keywords: severe asthma, nasal polyposis, interleukin 4 receptor, dupilumab

In particular, several environmental agents including aeroallergens, cigarette smoke, airborne pollutants, viral and bacterial pathogens activate the p38α isoform which in turn up-regulates the expression of multiple proinflammatory cytokines and chemokines, as well as the production of some fibrogenic factors. Therefore, p38 MAPK-induced bronchial inflammation and remodelling significantly contribute to the development, persistence and amplification of airflow limitation, which is the hallmark of asthma and COPD. Such advances in our understanding of p38 role in the pathobiology of the above widespread, chronic obstructive respiratory diseases, have led to consider p38 MAPK as a suitable molecular target for novel treatment strategies. Indeed, many studies have been carried out in both animal and clinical settings, with the aim of evaluating the potential therapeutic effects of p38 MAPK inhibitors in both asthma and COPD.Keywords: asthma, COPD, airway inflammation, p38-MAPK, p38-MAPK inhibitors

However, so far only a few real-life studies have been published with regard to the use of this anti-IL-5 receptor humanized monoclonal antibody.Objective: The primary aim of this multicenter observational investigation has been to assess the therapeutic effects of benralizumab in patients with severe uncontrolled, corticosteroid refractory eosinophilic asthma. The secondary objective was to evaluate the efficacy of benralizumab with regard to positive or negative skin prick test (SPT).Methods: Clinical, functional, and laboratory parameters were evaluated in order to verify the therapeutic actions of benralizumab in atopic and non atopic subjects with difficult-to-treat eosinophilic asthma. Moreover, a comparative evaluation was carried out in relation to the presence or absence of SPT positivity.Results: After 6 months of add-on biological therapy with benralizumab, our 111 patients experienced a marked improvement of their severe eosinophilic asthma, expressed by significant changes in asthma exacerbation rate, prednisone intake, daily use of short-acting β2-adrenergic agonists (SABA), asthma control test (ACT) score, asthma quality of life questionnaire (AQLQ) score (56 patients), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), blood eosinophil count, blood basophil count (59 patients), and fractional exhaled nitric oxide (FeNO) levels (39 patients). In addition, significantly more effective outcomes were detected in patients with positive SPT, when compared to subjects with negative SPT, only in regard to asthma exacerbation number, ACT score, and daily SABA utilization. No significant correlation was found between serum IgE concentrations and each of all measured parameters.Conclusion and Clinical Relevance: Taken together, the results of this real-world study indicate that in both allergic and non-allergic subjects benralizumab can be used as a valuable pharmacotherapeutic option for add-on biological therapy of severe eosinophilic asthma, regardless of SPT positivity or negativity.Keywords: severe eosinophilic asthma, allergic and non-allergic phenotypes, asthma exacerbations, IL-5 receptor, benralizumab

Benralizumab, targeting the interleukin-5 receptor alpha, proved effective in inducing rapid eosinophil depletion and amelioration of symptoms and lung function; it also allowed to reduce exacerbations and the use of oral corticosteroids (OCS). The present case series, spanning different subtypes of SEA, aimed at expanding the real-world experience with benralizumab in Italy.Patients and Methods: We collected data from SEA patients treated with benralizumab, at baseline and during treatment. We focused on the effects of benralizumab in the following conditions and endpoints: i) overlap between high-IgE and high-eosinophilic asthma; ii) presence of nasal polyposis as comorbidity; iii) corticosteroid-sparing effect; iv) patient perception.Results: Ten SEA patients (females: N=7; age range: 19– 70 years) referred to 8 Italian Centers and treated with benralizumab were included, presenting with several comorbidities such as non-allergic disease (8/10), atopy (3/10), high IgE (5/10) and nasal polyposis (6/10). Overall, benralizumab yielded optimal disease control in all patients, particularly in terms of rapid clinical and functional improvement, decreased systemic steroid need (OCS therapy was completely discontinued in 7 cases) and amelioration of patient quality of life, except for 1 case, in whom other conditions not related to benralizumab therapy interfered with the patient perception.Conclusion: Our findings further support the efficacy and safety of benralizumab observed in randomized clinical trials, providing even better results for lung function improvement.Keywords: benralizumab, IL-5 receptor, oral corticosteroids, overlap IgE/eosinophilic asthma, polyposis, real world, severe eosinophilic asthma

Materials and methods: A Delphi consensus project investigated the early management of COPD. We formulated two questionnaires for completion by pneumologists in Italy. Results: A total of 207 specialists completed questionnaire 1 and 184 of them questionnaire 2, between November 2016 and October 2017. Early diagnosis of COPD was considered uncommon for 93.2% of the expert panel. Regardless of the definition of “early diagnosis” – a diagnosis made before the clinical manifestation of the disease for most responders (60.4%) – experts were confident of the positive effects of early disease management, which they consider is effective in modifying the natural history of the disease. Lack of awareness of the disease was considered the first limiting factor to early COPD management for 78% of respondents. The most effective steps to reduce functional decline were considered to be smoking cessation, followed by long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA), LAMA, LABA, and finally inhaled corticosteroid/LABA (P

Outcomes including forced expiratory volume in 1 second (FEV1), Transition Dyspnea Index (TDI) scores, St George’s Respiratory Questionnaire (SGRQ) scores, exacerbations, exercise tolerance (endurance time [ET]), inspiratory capacity (IC), and rescue medication use were evaluated.Results: In total, 27 studies were included in the review. LABA/LAMA FDCs significantly improved lung function (FEV1) at 12 weeks compared with LABA or LAMA or LABA/ICS. These effects were maintained over time. Significant improvements with LABA/LAMA FDCs vs each evaluated comparator were also observed in TDI and SGRQ scores, even if significant differences between different LABA/LAMA FDCs were detected. Only the LABA/LAMA FDC indacaterol/glycopyrronium has shown superiority vs LAMA and LABA/ICS for reducing exacerbation rates, while olodaterol/tiotropium and indacaterol/glycopyrronium have been shown to improve ET and IC vs the active comparators. Rescue medication use was significantly reduced by LABA/LAMA FDCs vs the evaluated comparators. LABA/LAMA FDCs were safe, with no increase in the risk of adverse events with LABA/LAMA FDCs vs the monocomponents.Conclusion: Evidence supporting the efficacy of LABA/LAMA FDCs for COPD is heterogeneous, particularly for TDI and SGRQ scores, exacerbation rates, ET, and IC. So far, indacaterol/glycopyrronium is the LABA/LAMA FDC that has the strongest evidence for superiority vs LABA, LAMA, and LABA/ICS FDCs across the evaluated outcomes. LABA/LAMA FDCs were safe; however, more data should be collected in a real-world setting to confirm their safety. Keywords: LABA, LAMA, fixed-dose combination, COPD, systematic review

In particular, eosinophilic airway inflammation is a common pathologic trait of both allergic and nonallergic asthma. The key cytokine responsible for maturation, activation, recruitment, and survival of eosinophils is interleukin (IL)-5, which is mainly produced by T helper 2 (Th2) lymphocytes and group 2 innate lymphoid cells. Therefore, for uncontrolled patients with severe eosinophilic asthma, who are not fully responsive to corticosteroids, IL-5 represents a very important molecular target for add-on biological therapies. Among these new treatments, anti-IL-5 monoclonal antibodies such as mepolizumab and reslizumab have been developed and clinically evaluated. Furthermore, benralizumab is currently the only available biologic drug that specifically binds to the IL-5 receptor, thus preventing the interaction with its ligand and the consequent pro-inflammatory effects. The effectiveness of benralizumab in improving severe eosinophilic asthma has been well-documented by many randomized controlled trials.

Moreover, mepolizumab is also currently included within the step 5 of the Global Initiative for Asthma guidelines, as an add-on therapy for severe uncontrolled asthma. The relevant therapeutic benefits detectable in patients with refractory eosinophilic asthma receiving mepolizumab depend on the pivotal pathogenic role played by IL-5 in these subjects. Indeed, IL-5 is the key cytokine responsible for maturation, activation, proliferation, and survival of eosinophils. Therefore, IL-5 represents a strategic molecular target for anti-eosinophilic treatments. By selectively inhibiting the biological actions of IL-5, mepolizumab provides a valuable therapeutic option for patients with severe eosinophilic asthma, refractory to standard treatments including inhaled and even systemic corticosteroids. In particular, the very important advantages linked to the use of mepolizumab in these difficult-to-treat asthmatic individuals have been well documented by several different trials performed worldwide.

International guidelines increasingly recognize that a standard “one size fits all” approach is no longer an effective approach to achieve optimal treatment outcomes, and a number of disease phenotypes have been proposed for asthma, which has the potential to guide treatment decisions. Among the many asthma phenotypes, allergic asthma represents the widest and most easily recognized asthma phenotype, present in up to two-thirds of adults with asthma. Immunoglobulin E (IgE) production is the primary and key cause of allergic asthma leading to persistent symptoms, exacerbations and a poor quality of life. Therefore, limiting IgE activity upstream could stop the entire allergic inflammation cascade in IgE-mediated allergic asthma. The anti-IgE treatment omalizumab has an accepted place in the management of severe asthma (Global Initiative for Asthma [GINA] step 5) and represents the first (and, currently, only) targeted therapy with a specific target in severe allergic asthma. This review summarizes current knowledge of the mechanisms and pathogenesis of severe asthma, examines the actual role of IgE in asthma and the biological rationale for targeting IgE in allergic asthma and reviews the data for the efficacy and safety of omalizumab in the treatment of severe asthma. Current knowledge of the role of IgE in asthma, extensive clinical trial data and a decade of use in clinical practice has established omalizumab as a safe and effective targeted therapy for the treatment of patients with severe persistent IgE-mediated allergic asthma.

Because of its property to relax smooth muscle it is used in pharmacology for the treatment of airway diseases (ie, chronic obstructive pulmonary disease, asthma). However, this effect on smooth muscle is dose dependent and it is related to the development of side effects. Recently, an increasing body of evidence suggests that theophylline, at low concentrations, also has anti-inflammatory effects related to the activation of histone deacetylases. In this study, we evaluated the effects of theophylline alone and in combination with corticosteroids on human bronchial epithelial cells under inflammatory stimuli. Theophylline administrated alone was not able to reduce growth-stimulating signaling via extracellular signal-regulated kinases activation and matrix metalloproteases release, whereas it strongly counteracts this biochemical behavior when administered in the presence of corticosteroids. These data provide scientific evidence for supporting the rationale for the pharmacological use of theophylline and corticosteroid combined drug.

Therefore, these subjects can obtain significant therapeutic benefits by additional biologic treatments targeting interleukin-5 (IL-5), given the key pathogenic role played by this cytokine in maturation, activation, proliferation, and survival of eosinophils. In particular, reslizumab is a humanized anti-IL-5 monoclonal antibody that has been found to be an effective and safe add-on therapy, capable of decreasing asthma exacerbations and significantly improving disease control and lung function in patients experiencing persistent allergic or nonallergic eosinophilic asthma, despite the regular use of moderate-to-high doses of inhaled corticosteroids. These important therapeutic effects of reslizumab, demonstrated by several controlled clinical trials, have led to the recent approval by US Food and Drug Administration of its use, together with other antiasthma medications, for the maintenance treatment of patients suffering from severe uncontrolled asthma.

In particular, these therapeutic agents are mostly long-acting compounds utilized via inhalation, and include LAMA (long-acting muscarinic receptor antagonists) and LABA (long-acting β2-adrenoceptor agonists). Because LAMA and LABA induce bronchodilation by distinct mechanisms of action, LABA/LAMA combinations provide a reciprocal potentiation of the pharmacological effects caused by each component. Hence, many COPD patients who do not achieve a satisfactory control of their symptoms using a single, either LAMA or LABA bronchodilator, can experience relevant benefits with the use of LAMA/LABA fixed combinations. Many different LAMA/LABA combinations have been recently developed and evaluated in randomized clinical trials. In this context, our review focuses on the pharmacological mechanisms underpinning the bronchodilation elicited by the LAMA tiotropium bromide and the LABA olodaterol. We also discuss the results of the most important clinical studies carried out in COPD patients to assess the efficacy and safety of tiotropium/olodaterol combinations.Keywords: LAMA, LABA, tiotropium, olodaterol, dual bronchodilation, tiotropium/olodaterol combinations

In particular, given the key role played by interleukin (IL)-4 and IL-13 in the pathophysiology of the most typical aspects of asthma, such as chronic airway inflammation, tissue remodeling, and bronchial hyperresponsiveness, these pleiotropic cytokines are now considered as suitable therapeutic targets. Among the recently developed antiasthma biologic drugs, the monoclonal antibody dupilumab is very promising because of its ability to inhibit the biological effects of both IL-4 and IL-13. Indeed, dupilumab prevents IL-4/13 interactions with the α-subunit of the IL-4 receptor complex. A recent trial showed that in patients with difficult-to-control asthma, dupilumab can markedly decrease asthma exacerbations and improve respiratory symptoms and lung function; these effects were paralleled by significant reductions in T-helper 2-associated inflammatory biomarkers. However, further larger and longer trials are required to extend and validate these preliminary results, and also to carefully study the safety and tolerability profile of dupilumab.

This drug inhibits allergic responses by binding to serum IgE, thus preventing interaction with cellular IgE receptors. Omalizumab is also capable of downregulating the expression of high affinity IgE receptors on inflammatory cells, as well as the numbers of eosinophils in both blood and induced sputum. The clinical effects of omalizumab include improvements in respiratory symptoms and quality of life, paralleled by a reduction of asthma exacerbations, emergency room visits, and use of systemic corticosteroids and rescue bronchodilators. Omalizumab is relatively well-tolerated, and only rarely induces anaphylactic reactions. Therefore, this drug represents a valid option as add-on therapy for patients with severe persistent allergic asthma inadequately controlled by high doses of standard inhaled treatments.Keywords: omalizumab, anti-IgE, severe asthma

Objective. It is unclear whether Benralizumab effectiveness in severe eosinophilic asthma can be influenced by nasal polyposis (NP) or allergic status associations. We evaluated whether Benralizumab long-term efficacy in asthma outcomes could be different in subjects with atopy (SAEA) compared to the effectiveness in those without allergies (SNAEA) and in individuals with NP compared to those without NP. Methods. This observational retrospective study considered 95 consecutive patients divided into allergic (SAEA; n:65[68.4%]; skin prick tests positive [SPT] and/or IgE values ≥100 UI/mL), and non-allergic (SNAEA; n:30[31.6%], SPT negative and normal IgE levels<100 UI/ mL). Overall population was also divided into two groups according to NP presence (NP+:39[41%] and NP-:56[59%]). Benralizumab treatment mean was19.7±7.2 months (range 12-35). Results. No differences in Benralizumab effectiveness were found in asthma outcomes in patients with/without NP. SNOT-22 improvement was higher in NP+ (-22±24) compared to NP- groups (6.33±15.5;p=0.055). FEV1 (16.33±19.22%), ACT(7.45±3.95) increases and frequency of SABA use (3.37±4.99) reduction were higher in SAEA compared to what obtained in non-allergic subjects (FEV1:8.15±15.6%,p=0.043; ACT:4.89±3.57,p=0.005; SABA use:- 1.16±1.84;p=0.015). 93.8% of SAEA patients whereas only 72.2% of SNAEA individuals reduced OC doses at least half after Benralizumab (p=0.035). These results were partially confirmed by linear regression models showing associations between allergic status and FEV1, ACT and SABA use changes (β=8.37;p=0.048, β=2.056;p=0.033 and β=- 2.184;p=0.042 respectively). Conclusion. Benralizumab effectiveness in asthma appears to be independent of NP presence. The allergic eosinophilic disease, compared to just eosinophilic asthma, may be a more severe phenotype. Benralizumab may have greater efficacy in SAEA on some outcomes. [ABSTRACT FROM AUTHOR]
