Real-world clinical remission of severe asthma with benralizumab in Spanish adults with severe asthma.

OBJECTIVE: Patients with severe eosinophilic asthma experience high risk of exacerbations and reduced quality of life. Benralizumab, a monoclonal antibody binding to IL-5 receptor α subunit, is an approved drug for its treatment. The objective was to describe clinical remission after benralizumab prescription in routine clinical practice. METHODS: Retrospective multicenter study with data from four hospitals in Valencian Community (Spain) with asthma units between 2019 and 2020. Data was gathered at baseline and after 12 months. We considered clinical remission after 1 year if the patient remained without exacerbations and use of systemic corticosteroids and with good clinical control and normal lung function. RESULTS: Data from 139 patients was gathered. At the 12-month follow-up, 44.1% were in clinical remission, since 84.0%, 77.5%, 51.0% and 95.5% of patients did not experience exacerbations, had total asthma control test score of ≥20, prebronchodilator FEV1 of ≥80% and did not use systemic corticosteroids. A significant reduction of long-acting muscarinic antagonists (p = 0.0001), leukotriene receptor antagonists (p = 0.0326), oral corticosteroids (p < 0.0001) and short-acting beta agonists (p = 0.0499) was observed. Baseline factors with greatest individual influence on clinical remission were employment situation, tobacco use, comorbidity number, eosinophil value, number of exacerbations, FEV1, emergency visit number, and ACT, MiniAQLQ and TAI scores. Final analysis of multiple logistic regression indicated that having baseline FEV1 value below 80% increases remission chance 9.7 times a year compared to FEV1 >80%. CONCLUSION: Clinical remission after treatment with benralizumab is achievable in a high percentage of patients with severe asthma eosinophilia not controlled in real life.

A cross-sectional study to evaluate utility measure and health-related quality of life (HRQoL) among patients with severe uncontrolled asthma in Spain.

BACKGROUND AND PURPOSE OF THE STUDY: The utility measure is a method to quantify health-related quality of life according to the preference values that patients attach to their health status. This study aimed to estimate the utility measure of patients with controlled and uncontrolled severe asthma (SA) in Spain, separately. Additionally, other characteristics (sociodemographic, clinical, and healthcare resource use [HCRU]) were also assessed for both SA populations. METHODS: This cross-sectional study included 159 patients with SA in Spain. Data were collected from medical records and directly from the patients during the study visit. Asthma Control Questionnaire (ACQ)-5 was used to classify patients with controlled and uncontrolled SA. RESULTS: Most of the patients were female (72.0% uncontrolled SA and 63.6% controlled SA). The mean (SD) EuroQol-5D (EQ-5D-5L) score was 0.88 (0.14) and 0.70 (0.25) in controlled and uncontrolled SA, respectively. The mean (SD) Asthma Quality-of-Life-5D (AQL-5D) score was 0.93 (0.09) and 0.85 (0.09) in controlled and uncontrolled SA, respectively. Emergency visits (19.2 vs. 2.7%) and hospitalizations (7.7% vs. no hospitalization) were more common among uncontrolled SA than controlled SA. Mean (SD) number of visits to primary care and pneumologists in uncontrolled SA vs. controlled SA was 4.1 (2.8) vs. 2.5 (3.0) and 3.7 (3.5) vs. 2.8 (2.2), respectively. CONCLUSION: The study provides data on utility measures among patients with SA in Spain for the first time. Patients with uncontrolled SA had lower HRQoL and higher HCRU than patients with controlled SA. Therefore, the implementation of measures that improve HRQoL among patients with uncontrolled SA is highly recommended.

Despite the existence in Spain of validated asthma questionnaires, the impact of severe asthma on quality of life, depending on whether it is controlled or not, had never been assessed.This study, which included 159 patients, was conducted to fill the gap above by obtaining two utility measures for quality of life, a generic one using the EQ-5D questionnaire (which can be used for comparison with other chronic conditions) and an asthma-specific one using the AQL-5D questionnaire.Patients with uncontrolled SA had a lower utility measure than patients with controlled disease and, therefore, a lower quality of life. In addition, patients with uncontrolled SA also had higher use of healthcare resources.These results highlight that the implementation of measures that improve the quality of life among patients with uncontrolled SA is highly recommended.

Patient-reported outcome measures in severe asthma: an expert consensus.

OBJECTIVE: The study aimed to reach a consensus on the most relevant patient-reported outcomes (PROs), the corresponding measures (PROMs), and measurement frequency during severe asthma patient follow-up. METHODS: Two Delphi rounds were conducted. The questionnaire was developed based on a systematic literature review, a focus group with patients, and a nominal group with experts. It assessed PROs' relevance and the appropriateness (A) and feasibility (F) of PROMs using a Likert scale (1=totally agree; 9=totally disagree). The consensus was established when ≥75% of participants agreed (1-3) or disagreed (7-9). RESULTS: Sixty-three professionals (25 hospital pharmacists, 14 allergists, 13 pulmonologists, and 11 nurses) and 5 patients answered the Delphi questionnaire. A consensus was reached on all PROs regarding their relevance. Experts agreed on the use of ACT (A:95.24%; F:95.24%), mini AQLQ (A:93.65; F:79.37%), mMRC dyspnea scale (A:85.71%; F:85.71%), TAI (A:92.06%; F:85.71%), MMAS (A:75.40%; F:82%), and the dispensing register (A:96.83%; F:92.06%). Also considered suitable were: SNOT-22 (A:90.48%; F:73.80%), PSQI (A:82.54; F:63.90%), HADS (A:82.54; F:64%), WPAI (A:77.78%; F:49.20%), TSQM-9 (A:79.37; F:70.50%) and knowledge of asthma questionnaire (A:77%; F:68.80%); however, their use in clinical practice was considered unfeasible. Panelists also agreed on the appropriateness of EQ-5D, which was finally included despite being considered unfeasible (A: 84.13%; F:67.20%) in clinical practice. Agreement was reached on using ACT, TAI, mMRC, and a dispensing register every three months; mini-AQLQ and MMAS every six months; and EQ-5D every twelve months. CONCLUSION: This consensus paves the way toward patient-centered care, promoting the development of strategies supporting routine assessment of PROs in severe asthma management.

Burden of refractory and unexplained chronic cough on patients' lives: a cohort study.

Background: Chronic cough (cough lasting for ≥8 weeks) can lead to significant impairment in quality of life (QoL). Using patient-reported outcomes, this cohort study assessed the perceived impact of chronic cough on QoL and everyday life in patients from outpatient hospital clinics with refractory chronic cough (RCC) or unexplained chronic cough (UCC). Methods: This was a multicentre, non-interventional survey study. Cough severity was assessed on a 0-100 mm Visual Analogue Scale (VAS). Frequency, intensity and disruptiveness of cough were assessed using an adaptation of the Cough Severity Diary. The impact of cough on QoL was assessed using the Leicester Cough Questionnaire (LCQ). The physical impact of cough and associated impact on everyday life activities were explored using purpose-designed questions. Results: 191 patients responded to the survey; 121 (63.4%) had RCC and 149 were women (78.0%). Mean score on the cough severity VAS was 62.9 mm. Mean LCQ total score of 11.9 indicated reduced QoL. Cough impaired patients' everyday life, including the inability to speak fluently (58.0% of patients) and feeling tired/drained (46.6%). Women perceived poorer chronic cough-related QoL than men, as reflected by lower LCQ scores, and greater impairment of physical health, including cough-related stress urinary incontinence, and psychological health. Conclusions: Patients with RCC/UCC experience a significant burden in their everyday life, including impaired QoL, and perceive a negative impact on physical and psychological health and everyday activities, affecting work, relationships and leisure activities. The impact appears to be greater in women than men for several of the aspects studied.

Achieving clinical outcomes with benralizumab in severe eosinophilic asthma patients in a real-world setting: orbe II study.

BACKGROUND: The ORBE II study aimed to describe the characteristics and clinical outcomes of adult patients with severe eosinophilic asthma (SEA) treated with benralizumab in a real-world setting in Spain. METHODS: ORBE II (NCT04648839) was an observational, retrospective cohort study in adult SEA patients who had been prescribed benralizumab. Demographic and clinical data of 204 SEA patients were collected 12 months prior to benralizumab initiation (baseline) and at follow-up. Exacerbation rate, asthma symptoms, maintenance oral corticosteroid (OCS) use and lung function were evaluated, among other variables. RESULTS: A total of 204 SEA patients were evaluated. Mean (standard deviation, SD) age of the study population was 56.4 (12.4) years, 62.3% were women and mean (SD) duration of asthma was 15.1 (12.7) years. Median (Q1-Q3) follow-up duration was 19.5 (14.2-24.2) months. At baseline, 72.6% of the overall population (OP) presented blood eosinophil counts ≥ 300 cells/µL; 36.8% had comorbid chronic rhinosinusitis with nasal polyps (CRSwNP); 84.8% reported at least one severe exacerbation, and 29.1% were OCS-dependent. At 1 year of follow-up, patients receiving benralizumab treatment had a 85.6% mean reduction in exacerbations from baseline, and 81.4% of patients achieved zero exacerbations. We also found a clinically relevant mean (SD) increase in pre-bronchodilator (BD) FEV1 of 331 (413) mL, with 66.7% of patients achieving a pre-BD FEV1 increase ≥ 100 mL, and 46.3% of patients achieving a pre-BD FEV1 ≥ 80% of predicted. Regarding symptom control, 73.8% of the OP obtained an ACT score ≥ 20 points. After 1 year of follow-up, mean reduction in the daily OCS dose was 70.5%, and complete OCS withdrawal was achieved by 52.8% of the OCS-dependent patients. Almost half (43.7%) of the OP on benralizumab met all four criteria for clinical remission. Patients with concomitant CRSwNP obtained similar or enhanced outcomes. CONCLUSIONS: These data support the real-world benefits of benralizumab in SEA patients, and particularly in those with concomitant CRSwNP. TRIAL REGISTRATION: NCT04648839.

Health-related quality of life and radiological and functional lung changes of patients with COVID-19 Pneumonia 3 and 10 months after discharge.

BACKGROUND: Few studies have evaluated the long-term impact on health-related quality of life (HRQoL) in patients who have been hospitalized for COVID-19 pneumonia. Specific follow-up should be carried out to detect and treat possible pulmonary abnormalities, and the worsening of HRQoL should be estimated to target necessary resources for care of these patients after acute phase. The objective was to know the impact on HRQoL of patients who have been admitted for COVID-19 pneumonia, and to evaluate the clinical-radiological and functional changes of patients who have overcome COVID-19 pneumonia at 3 and 10 months of follow-up. METHODS: Prospective observational study of patients who required hospitalization for COVID-19 pneumonia between April and December 2020. All patients filled out the EuroQol five-dimension (EQ-5D) questionnaire with the EuroQol Visual Analogue Scale (E-VAS) for self-assessment of health status. Respiratory function tests and chest X-ray were carried out at 3 and 10 months of follow-up. RESULTS: 61 patients were included in the study. The need for ventilatory support was associated with anxiety/depression on the EQ-5D scale, as well as patients admitted to the intensive care unit (ICU). The mean EQ-5D and E-VAS index scores decreased with hospitalization time, the number of days spent in intermediate respiratory care unit (IRCU) and the level of dyspnoea at the beginning of the hospitalization period. Pulmonary sequelae were observed in 25 patients (41%) at 3 months and 17 (27.9%) at 10 months. Patients improve their forced vital capacity (FVC) by 196 ml (p = 0.001) at 10 months as well as 9% in diffusing capacity of lung for carbon monoxide (DLCO) (p = 0.001) at 10 months. DLCO was found to be correlated to lymphopenia and time spent in IRCU. Low FVC values were detected 10 months after discharge for subjects exhibiting high levels of dyspnoea at 3 months after discharge. CONCLUSIONS: Hospitalization for COVID-19 pneumonia affects the HRQoL of patients, with greater anxiety/depression in those who were more serious affected and are younger. A significant percentage of patients present fibrotic abnormalities and lung function impairment at the first and second follow-up after discharge.

Potential impact of mepolizumab in stepping down anti-osteporotic treatment in corticosteroid-dependent asthma.

Oral corticosteroids (OCS) are commonly used for the acute management of severe asthma exacerbations or as maintenance therapy; however, chronic use is associated with significant toxicities, e.g., osteoporosis. In the REal worlD Effectiveness and Safety (REDES) study of mepolizumab in a multicentric Spanish cohort of asthma patients, mepolizumab effectively reduced clinically severe asthma exacerbations and decreased OCS dependence. This post-hoc analysis further evaluates mepolizumab's de-escalation effect on OCS dose. Patients enrolled in REDES who had OCS consumption data available for 12 months pre- and post-mepolizumab treatment were included in this analysis. Primary outcomes were to determine the change in the proportion of patients eligible for anti-osteoporotic treatment due to the changes in OCS consumption before and after 1 year of mepolizumab treatment. All analyses are descriptive. Approximately one-third (98/318; 30.8%) of patients in REDES were on maintenance OCS at the time of mepolizumab treatment initiation. In REDES, mean cumulative OCS exposure decreased by 54.3% after 1 year of treatment. The proportion of patients on high-dose OCS (≥7.5 mg/day) fell from 57.1% at baseline to 28.9% after 12 months of mepolizumab treatment. Thus, 53.6% of OCS-dependent asthma patients treated with mepolizumab would cease to be candidates for anti-osteoporotic treatment according to guidelines thresholds.

Documento de consenso de expertos para el control del asma en personas mayores / Expert consensus recommendations for the management of asthma in older adults

El asma constituye un problema de salud pública presente en pacientes de cualquier edad, aunque continúa existiendo cierta tendencia a asumir de forma errónea que dicha entidad resulta casi siempre exclusiva de la infancia y de gente joven. Los estudios epidemiológicos señalan que, a partir de la sexta década de la vida, la prevalencia de esta enfermedad en países como España alcanza el 6-10%, con mayor predominio entre las mujeres de 64 a 75 años. Asimismo, dos tercios de las muertes debidas al asma acontecen en esta etapa de la vida, llegando a ocasionar un número de ingresos sustancial, estancias hospitalarias más prolongadas y, desde el punto de vista del financiador, unos costes económicos directos notables. En la actualidad el asma en las personas mayores (65 años o más) constituye un tema de enorme preocupación, cuya realidad se encuentra infravalorada e infratratada, por lo que resulta del todo necesario establecer unas recomendaciones adecuadas para el diagnóstico y tratamiento de la enfermedad en esta población de edad. Con este objetivo nació este consenso que recoge la evidencia disponible más actualizada. Las recomendaciones/conclusiones que se proponen son el resultado de un consenso de tipo nominal desarrollado a lo largo del año 2019 y que han sido validadas por los panelistas en sucesivas rondas de votación. (AU)

Asthma is a public health problem in patients of any age, although there is still a tendency to erroneously assume that it is almost always confined to children and young people. Epidemiological studies indicate that, from the sixth decade of life, the prevalence of this disease in countries such as Spain reaches 6-10%, with a higher prevalence among women aged 64 to 75 years. In addition, two-thirds of asthma deaths occur at this stage of life, resulting in a substantial number of hospital admissions, longer hospital stays and, from a finance point of view, significant direct economic costs. Asthma in older adults (65 years or older) is now a matter of great concern, the reality of which is underestimated and undertreated. It is therefore essential to establish appropriate recommendations for the diagnosis and treatment of asthma in the aging population. This consensus, which brings together the latest evidence available, was conceived with this objective. The proposed recommendations/conclusions are the result of a nominal consensus developed throughout 2019 and validated by panellists in successive rounds of voting. (AU)

The Response to Biologics is Better in Patients with Severe Asthma Than in Patients with Asthma-COPD Overlap Syndrome.

Although biologics have demonstrated to be effective in T2-high asthma patients, there is little experience with these drugs in asthma-COPD overlap (ACO). The aim of this study was to compare the effectiveness of biologics in these two conditions. We included 318 patients (24 ACO and 297 asthma) treated with monoclonal antibodies and followed for at least 12 months. Omalizumab was the most frequently employed biologic agent both in patients with ACO and asthma. Asthma control test (ACT) scores after at least 12 months of biologic therapy were not significantly different between groups. The percentage of patients with ≥1 exacerbation and ≥1 corticosteroid burst was significantly higher in ACO patients (70.8 vs 27.3 and 83.3% vs 37.5%, respectively), whereas the percentage of "controlled" patients (with no exacerbations, no need for corticosteroids and ACT ≥ 20) was significantly lower (16.7% vs 39.7%). In conclusion, this report suggests that patients with ACO treated with biologics reach worse outcomes than asthma patients.

[Consensus document for severe asthma in adults. 2022 update]. / Documento de consenso de asma grave en adultos. Actualización 2022.

Severe asthma is a heterogeneous syndrome with several clinical variants and often represents a complex disease requiring a specialized and multidisciplinary approach, as well as the use of multiple drugs. The prevalence of severe asthma varies from one country to another, and it is estimated that 50% of these patients present a poor control of their disease. For the best management of the patient, it is necessary a correct diagnosis, an adequate follow-up and undoubtedly to offer the best available treatment, including biologic treatments with monoclonal antibodies. With this objective, this consensus process was born, which began in its first version in 2018, whose goal is to offer the patient the best possible management of their disease in order to minimize their symptomatology. For this 2020 consensus update, a literature review was conducted by the authors. Subsequently, through a two-round interactive Delphi process, a broad panel of asthma experts from SEPAR and the regional pulmonology societies proposed the recommendations and conclusions contained in this document.

Real-world study in severe eosinophilic asthma patients refractory to anti-IL5 biological agents treated with benralizumab in Spain (ORBE study).

BACKGROUND: Benralizumab, a monoclonal antibody targeting the human interleukin-5 (IL-5) receptor (IL-5R), was used before marketing authorisation in Spain in a real world setting as part of an early-access programme (EAP) to treat patients with severe eosinophilic asthma with prior insufficient response or intolerance to anti-IL5 treatment (mepolizumab or reslizumab). The objective of this study is to describe the patient profile candidate for treatment and to assess benralizumab effectiveness. METHODS: This is an observational, retrospective, multicentre study in severe eosinophilic asthma patients refractory to other biological agents targeting the IL-5 pathway. Baseline characteristics included closest data, from the previous 12 months, to benralizumab treatment onset (index date). Patients were followed until the last treatment dosage while EAP was active (March to December 2018). Effectiveness was evaluated versus baseline, in patients who received at least three doses, with asthma control test (ACT), Mini Asthma Quality of Life Questionnaire (MiniAQLQ), annual severe exacerbation rate, oral corticosteroids treatment (OCS) and asthma-related healthcare resources utilization. RESULTS: Twenty-seven patients treated with benralizumab were included in the analysis. Effectiveness was assessed in 19 patients. Both questionnaires showed clinically meaningful differences, i.e. ACT score ≥ 3 and MiniAQLQ score ≥ 0.5, compared with baseline [mean (SD), 3.3 (6.8) and 1.2 (1.9), respectively]. Patients treated with OCS decreased during follow-up from 88.9% (n = 24/27) at baseline to 78.9% (n = 15/19) and 31.6% (n = 6/19) had an OCS dose reduction ≥ 50%. The difference in annual severe exacerbation rate during follow-up showed a significant reduction vs. baseline (2.12 per patient-year, 95% CI 0.99-3.24, p = 0.002). The differences in annual rate of non-scheduled primary care and specialist visits during follow-up indicated a significant decrease [2.28 per patient-year (95% CI 1.55-3.01; p < 0.001) and 1.47 per patient-year (95% CI 0.65-2.30; p = 0.004), respectively], as well as the difference in annual rate of number of emergency department visits [1.18 per patient-year (95% CI 0.51-1.85; p = 0.007)]. CONCLUSIONS: These results suggest that severe eosinophilic asthma patients receiving benralizumab, presented clinically meaningful improvement in asthma control and asthma-related QoL as well as OCS dose reduction. Results also aim to significant reductions in annual severe exacerbation rates, non-scheduled primary care and specialist visits, and emergency department visits rates.
