A systematic review of the adverse events and economic impact associated with oral corticosteroids in asthma

Asthma management, focused on the use of oral corticosteroids: the opinions of Italian asthmatic patients

OBJECTIVE

Patients' perceptions of asthma symptoms, and attitudes regarding diagnosis and management, can affect their ability to reach good asthma control. The aim of the study was to explore patients' perceptions of asthma management, with focus on treatment with oral corticosteroids (OCS).

METHODS

A DOXAPHARMA survey was conducted. A questionnaire with 46 multiple choice questions was completed by 50 patients with severe uncontrolled asthma, and 258 with mild-moderate controlled or partly controlled asthma. Participants were representative of Italian asthmatic patients-with medium age, long asthma duration, delayed diagnosis, poor asthma control, and frequent exacerbations.

RESULTS

Many asthmatics reported inadequate pharmacologic treatment. The majority but not all patients regularly used ICS/LABA. Oral treatment was common, mainly with OCS, particularly in severe asthmatics. One-fourth of patients did not regularly use inhaled therapy, and adherence was poor, resulting in frequent OCS use to treat exacerbations, which were common in mild-moderate cases. Patients were fairly satisfied with asthma therapies, but many had concerns about long-term corticosteroid use. Patients complained about poor management of comorbidities associated with asthma and OCS use, but were generally satisfied with their patient/doctor relationships. Many patients failed to achieve optimal health-related quality of life (HRQoL), mainly those with severe asthma who used OCS treatment and emphasized how OCS therapy impacted QoL.

CONCLUSIONS

The survey results confirmed many problems related to mild-moderate and severe asthma management in Italy and highlighted the overuse of OCS rather than more effective and safe treatments, which had strong negative effects on HRQoL.

Association between asthma and cardiovascular diseases: A longitudinal follow-up study using a national health screening cohort

Background

Asthma has been suggested to be a risk factor for cardiovascular diseases (CVDs), although the evidence supporting this relationship is inconclusive. This study aimed to explore the long-term associations between asthma and asthma exacerbations with the occurrence of cardiovascular diseases (CVDs) such as ischemic heart disease (IHD), heart failure (HF), and cerebral stroke, utilizing data from a nationwide cohort.

Materials and methods

This study utilized data from the Korean National Health Insurance Service-Health Screening Cohort database (2002-2015), including information on 111,316 asthma patients and an equal number of 1:1 matched control participants. A propensity score overlap-weighted Cox proportional hazards regression model was used to analyze the overlap-weighted hazard ratios (HRs) of asthma and exacerbated asthma for cardiovascular diseases (CVDs) within this cohort.

Results

During the follow-up period, the incidence rate (IR) of IHD per 1000 person-years (PYs) was 7.82 in patients with asthma and 5.79 in controls. The IR of HF was 2.53 in asthmatic patients and 1.36 in controls. After adjustment for covariates, asthmatic patients exhibited 1.27-fold and 1.56-fold higher HRs for IHD (95% confidence interval (CI) = 1.23-1.37, P < 0.001) and HF (95% CI = 1.36-1.63, P < 0.001) than the controls, respectively. In addition, there was an increased HR for IHD and HF in the asthma exacerbation group compared with the nonexacerbated asthma group (adjusted HR, 1.29, 95% CI = 1.24-1.34, P < 0.001 for IHD and aHR 1.68, 95% CI = 1.58-1.79, P < 0.001 for HF). However, the occurrence of stroke was decreased in asthmatic patients compared with controls (aHR = 0.96, 95% CI = 0.93-0.99, P = 0.008).

Conclusions

Adults with asthma are more likely to develop CVDs. Additionally, severe asthma exacerbations are significantly associated with an increased occurrence of CVDs.

Mild asthma: Conundrums, complexities and the need to customize care

Mild and moderate asthma cover a wide range of asthma presentations, phenotypes and symptom burden, and account for the majority of people with asthma worldwide. Mild asthma has been difficult to define because of its heterogeneity and wide spectrum of impact and outcomes, including being associated with severe exacerbations. Assessment of mild-moderate asthma is best made by combining asthma symptom control and exacerbation risk as the principle means by which to determine treatment needs. Incontrovertible evidence and guidelines support treatment initiation with anti-inflammatory medication, completely avoiding reliever-only treatment of mild asthma. Shared decision making with patients and a treatable traits approach will ensure that a holistic approach is taken to maximize patient outcomes. Most importantly, mild asthma should be regarded as a reversible, potentially curable condition, remaining in long-term remission through minimizing triggers and optimizing care.

Analysis of comorbidities and multimorbidity in adult patients in the International Severe Asthma Registry

BACKGROUND

Investigation for the presence of asthma comorbidities is recommended by the Global Initiative for Asthma because their presence can complicate asthma management.

OBJECTIVE

To understand the prevalence and pattern of comorbidities and multimorbidity in adults with severe asthma and their association with asthma-related outcomes.

METHODS

This was a cross-sectional study using data from the International Severe Asthma Registry from 22 countries. A total of 30 comorbidities were identified and categorized a priori as any of the following: (1) potentially type 2-related comorbidities, (2) potentially oral corticosteroid (OCS)-related comorbidities, or (3) comorbidities mimicking or aggravating asthma. The association between comorbidities and asthma-related outcomes was investigated using multivariable models adjusted for country, age at enrollment, and sex (ie male or female).

RESULTS

Of the 11,821 patients, 69%, 67%, and 55% had at least 1 potentially type 2-related, potentially OCS-related, or mimicking or aggravating comorbidities, respectively; 57% had 3 or more comorbidities, and 33% had comorbidities in all 3 categories. Patients with allergic rhinitis, nasal polyposis, and chronic rhinosinusitis experienced 1.12 (P = .003), 1.16 (P < .001), and 1.29 times (P < .001) more exacerbations per year, respectively, than those without. Patients with nasal polyposis and chronic rhinosinusitis were 40% and 46% more likely (P < .001), respectively, to have received long-term (LT) OCS. All assessed potential OCS-related comorbidities (except obesity) were associated with a greater likelihood of LTOCS use (odds ratios [ORs]: 1.23-2.77) and, except for dyslipidemia, with a greater likelihood of uncontrolled asthma (ORs: 1.29-1.68). All mimicking or aggravating comorbidities assessed were associated with more exacerbations (1.24-1.68 times more), all (except bronchiectasis) with increased likelihood of uncontrolled asthma (ORs: 1.57-1.81), and all (except chronic obstructive pulmonary disease) with increased likelihood of LTOCS use (ORs: 1.37-1.57). A greater number of comorbidities was associated with worse outcomes.

CONCLUSION

In a global study, comorbidity or multimorbidity is reported in most adults with severe asthma and is associated with poorer asthma-related outcomes.

Dupilumab sustains efficacy in patients with moderate-to-severe type 2 asthma regardless of inhaled corticosteroids dose

BACKGROUND

Dupilumab, a human monoclonal antibody, blocks the shared receptor component for interleukins-4/13, key and central drivers of type 2 inflammation. The TRAVERSE (NCT02134028) open-label extension study demonstrated the long-term safety and efficacy of dupilumab in patients ≥12 years who completed a previous dupilumab asthma study. The safety profile was consistent with that observed in the parent studies. Here, we assess whether dupilumab sustains long-term efficacy in patients regardless of inhaled corticosteroid (ICS) dose at parent study baseline (PSBL).

METHODS

Patients from phase 2b (NCT01854047) or phase 3 (QUEST; NCT02414854) studies receiving high- or medium-dose ICS at PSBL and enrolled in TRAVERSE were included. We analyzed unadjusted annualized severe exacerbation rates, change from PSBL in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV1 ), 5-item asthma control questionnaire, and type 2 biomarkers in patients with type 2 asthma at baseline (blood eosinophils ≥150 cells/μL or fractional exhaled nitric oxide [FeNO] ≥25 ppb), and subgroups defined by baseline blood eosinophils or FeNO.

RESULTS

Of patients with type 2 asthma (n = 1666), 891 (53.5%) were receiving high-dose ICS at PSBL. In this subgroup, unadjusted exacerbation rates for dupilumab versus placebo were 0.517 versus 1.883 (phase 2b) and 0.571 versus 1.300 (QUEST) over the parent study (52 weeks) and remained low throughout TRAVERSE (0.313-0.494). Improvements in pre-BD FEV1 were sustained throughout TRAVERSE. Similar clinical efficacy was observed among patients receiving medium-dose ICS at PSBL and biomarker subgroups.

CONCLUSIONS

Dupilumab showed sustained efficacy for up to 3 years in patients with uncontrolled, moderate-to-severe type 2 asthma on high- or medium-dose ICS.

Impact of Initiating Biologics in Patients With Severe Asthma on Long-Term Oral Corticosteroids or Frequent Rescue Steroids (GLITTER): Data From the International Severe Asthma Registry

BACKGROUND

Effectiveness of biologics has neither been established in patients with high oral corticosteroid exposure (HOCS) nor been compared with effectiveness of continuing with HOCS alone.

OBJECTIVE

To examine the effectiveness of initiating biologics in a large, real-world cohort of adult patients with severe asthma and HOCS.

METHODS

This was a propensity score-matched, prospective cohort study using data from the International Severe Asthma Registry. Between January 2015 and February 2021, patients with severe asthma and HOCS (long-term OCSs for ≥1 year or ≥4 courses of rescue OCSs within a 12-month period) were identified. Biologic initiators were identified and, using propensity scores, matched 1:1 with noninitiators. The impact of biologic initiation on asthma outcomes was assessed using generalized linear models.

RESULTS

We identified 996 matched pairs of patients. Both groups improved over the 12-month follow-up period, but improvement was greater for biologic initiators. Biologic initiation was associated with a 72.9% reduction in the average number of exacerbations per year versus noninitiators (0.64 vs 2.06; rate ratio, 0.27 [95% CI, 0.10-0.71]). Biologic initiators were 2.2 times more likely than noninitiators to take a daily long-term OCS dose of less than 5 mg (risk probability, 49.6% vs 22.5%; P = .002) and had a lower risk of asthma-related emergency department visits (relative risk, 0.35 [95% CI, 0.21-0.58]; rate ratio, 0.26 [0.14-0.48]) and hospitalizations (relative risk, 0.31 [95% CI, 0.18-0.52]; rate ratio, 0.25 [0.13-0.48]).

CONCLUSIONS

In a real-world setting, including patients with severe asthma and HOCS from 19 countries, and within an environment of clinical improvement, initiation of biologics was associated with further improvements across multiple asthma outcomes, including exacerbation rate, OCS exposure, and health care resource utilization.

Oral corticosteroid use and sarcopenia-related traits in older people with chronic airway disease: a population-based study

Background

Sarcopenia is characterised by two major phenotypic components: low handgrip strength (HGS) and appendicular skeletal muscle index (ASMI). Oral corticosteroid (OCS) use is an important medication for acute respiratory exacerbations in patients with COPD and asthma. However, the association of OCS and sarcopenia components in older people is largely unexplored. The aim of this study was to examine the association between OCS use and HGS or ASMI in the general population and explore interactions with chronic airway diseases.

Methods

From the population-based Rotterdam Study, 5054 participants (age 69.0±8.8 years; 56% females) were included in the cross-sectional analysis and 1324 in the longitudinal analysis. Associations between OCS and muscle strength and mass were analysed using linear regression models adjusted for age, sex, fat %, height, kidney function, smoking and comorbidities.

Results

At baseline, ever-OCS users had lower handgrip strength (β= -0.48, 95% CI -0.84- -0.12) than never-OCS users, with cumulative frequency (≥10 OCS prescriptions)-dependent effects (β= -1.25, 95% CI -2.16- -0.33). COPD ever-OCS users, but not asthma, had lower handgrip strength (β= -0.98, 95% CI -1.91- -0.06) and lower lean mass (β= -0.14, 95% CI -0.27- -0.01) than never-OCS users. After 5.6 years of follow-up in those free of sarcopenia traits at baseline, COPD ever-OCS users developed lower handgrip strength (β= -1.64, 95% CI -2.87- -0.40) with frequency (β= -3.64, 95% CI -6.57- -0.72) and duration (β= -1.51, 95% CI -2.87- -0.15) association compared to never-OCS users.

Conclusions

OCS use is associated with a decline in handgrip strength in people with COPD in a cumulative frequency and duration-dependent manner. Routine muscle examination may be necessary for patients with COPD.

Definitions of non-response and response to biological therapy for severe asthma: a systematic review

Background

Biologics have proven efficacy for patients with severe asthma but there is lack of consensus on defining response. We systematically reviewed and appraised methodologically developed, defined and evaluated definitions of non-response and response to biologics for severe asthma.

Methods

We searched four bibliographic databases from inception to 15 March 2021. Two reviewers screened references, extracted data, and assessed methodological quality of development, measurement properties of outcome measures and definitions of response based on COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). A modified GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach and narrative synthesis were undertaken.

Results

13 studies reported three composite outcome measures, three asthma symptoms measures, one asthma control measure and one quality of life measure. Only four measures were developed with patient input; none were composite measures. Studies utilised 17 definitions of response: 10 out of 17 (58.8%) were based on minimal clinically important difference (MCID) or minimal important difference (MID) and 16 out of 17 (94.1%) had high-quality evidence. Results were limited by poor methodology for the development process and incomplete reporting of psychometric properties. Most measures rated "very low" to "low" for quality of measurement properties and none met all quality standards.

Conclusions

This is the first review to synthesise evidence about definitions of response to biologics for severe asthma. While high-quality definitions are available, most are MCIDs or MIDs, which may be insufficient to justify continuation of biologics in terms of cost-effectiveness. There remains an unmet need for universally accepted, patient-centred, composite definitions to aid clinical decision making and comparability of responses to biologics.

The burden of systemic corticosteroid use in asthma management in Asia

For most patients, asthma can be effectively managed using inhaled medications. However, patients who have severe and/or uncontrolled asthma, or who experience exacerbations, may require systemic corticosteroids (SCSs) to maintain asthma control. Although SCS are highly effective in this regard, even modest exposure to these medications can increase the risk for long-term, adverse health outcomes, such as type 2 diabetes, renal impairment, cardiovascular disease and overall mortality. Clinical and real-world data from studies investigating asthma severity, control and treatment practices around the globe have suggested that SCS are overused in asthma management, adding to the already substantial healthcare burden experienced by patients. Throughout Asia, although data on asthma severity, control and SCS usage are limited and vary widely among countries, available data strongly suggest a pattern of overuse consistent with the broader global trend. Coordinated changes at the patient, provider, institutional and policy levels, such as increasing disease awareness, promoting better adherence to treatment guidelines and increasing availability of safe and effective alternatives to SCS, are likely necessary to reduce the SCS burden for patients with asthma in Asia.

The use of systemic corticosteroids in asthma management in Latin American countries

The stepwise treatment approach recommended by the Global Initiative for Asthma (GINA) includes systemic corticosteroids (SCS) suggested as a final step if asthma is severe and/or difficult to treat. Yet, despite the effectiveness of SCS, they are also associated with potentially irreversible adverse outcomes such as type 2 diabetes, adrenal suppression, and cardiovascular disease. Based on recent data indicating that the risk of developing these conditions can increase after as few as 4 short-term (burst) courses of SCS, even patients with mild asthma who receive SCS occasionally for exacerbations are also at risk of these events. As a result, recent updates by GINA and the Latin American Thoracic Society recommend decreasing SCS use by optimizing administration of non-SCS therapies and/or increasing the use of alternatives, such as biologic agents. Recent and ongoing studies characterizing treatment patterns among patients with asthma have revealed alarming trends suggesting the widespread overuse of SCS around the world. In Latin America, asthma prevalence is approximately 17%, and data suggest that the majority of patients have uncontrolled disease. In this review, we summarize currently available data on asthma treatment patterns in Latin America, which indicate that SCS are prescribed to 20-40% of patients with asthma considered to be well controlled and over 50% of patients with uncontrolled disease. We also offer potential strategies to help reduce SCS use for asthma in everyday clinical practice.

Frailty and muscle weakness in elderly patients with asthma and their association with cumulative lifetime oral corticosteroid exposure

BACKGROUND

Frailty is a geriatric syndrome of age-related physiological decline, which is associated with higher mortality and decreased healthy life expectancy, and muscle weakness is one of the presentations of frailty. We investigated an association between lifetime oral corticosteroid (OCS) exposure with frailty and muscle weakness among elderly patients with asthma.

METHODS

We studied 203 consecutive elderly outpatients with asthma aged ≥60 years old. They were classified into three groups according to their cumulative lifetime OCS dose (lifetime non-users, lower-dose users, and higher-dose users), which was retrospectively estimated from the response to a structured questionnaire. The prevalence of frailty determined by the Kihon Checklist was compared between the three groups. Hand-grip strength, and lean mass index were also measured as markers of muscle strength.

RESULTS

Thirty-seven percent of the patients studied were considered frail. Higher cumulative lifetime OCS exposure was associated with a significantly higher prevalence of frailty (33% in lifetime non-users, 59% in lower-dose users, and 68% in higher-dose users; P for trend <0.005). This was also associated with lower hand-grip strength in both sexes (P for trend; 0.012 in men, and 0.020 in women), and lower lean mass index in men (P for trend 0.002). However, current doses of OCS were not significantly associated with these outcomes.

CONCLUSIONS

Cumulative lifetime OCS exposure was associated with a higher prevalence of frailty and muscle weakness. These findings emphasize the importance of minimizing lifetime OCS exposure for the prolongation of healthy life expectancy in patients with asthma.

Uso de glucocorticoides sistémicos para el tratamiento del asma grave: Consenso multidisciplinar español

Background and aim

Since their effectiveness was initially demonstrated, oral corticosteroids (OCS) have been routinely used to treat asthma. We now know that their usage is linked to the development of side effects such osteoporosis and adrenal insufficiency. This is an observational study based on Delphi methodology. The questionnaire was divided into 4 sections: OCS generalities, maintenance treatment, short-term treatment, and adverse events.

Materials and methods

Two rounds of a 68-item questionnaire were completed by a panel of 48 allergists and pneumologists.

Results

Definitions were agreed upon, as was the proper use of OCS in the treatment of severe asthma. The experts agreed that the use of OCS should be minimized as much as possible and that in the event of maintenance treatments, a slow and progressive tapering strategy should be used. They also emphasized the importance of standardizing the technique for measuring the amount of SCG delivered in both cases.

Conclusions

This consensus document attempts to bring together scientifically supported suggestions from specialists in the management of asthma to reduce the use of OCS in Spain.

Clinical burden related to oral corticosteroid treatment of severe asthma in Spain: LEVANTE study

Background: Severe asthma treatment with oral corticosteroids (OCS) added to inhaled corticosteroids and a long-acting β2-agonist (ICS-LABA) may result in more treatment burden and increased adverse effects.Objective and Methods: This ambispective multicenter observational study aimed at describing the clinical burden in patients with severe asthma on stable high-dose ICS-LABA who received OCS during ≥6 months (maintenance group) or ≥2 cycles in the previous 12 months (bursts group). Data collection comprised a retrospective 12-month baseline period and 2 follow-up visits at 3 and 6 months. Results: Eighty-nine patients were evaluable (30 on maintenance, 59 on bursts). At baseline, mean (SD) daily prednisone equivalent exposure in the total population was 24.6 (14.7) mg: 13.8 (9.4) mg on maintenance and 29.9 (14.3) mg on bursts. During the 6-month follow-up period, mean (SD) daily dose in the total cohort was 22.5 (18.8) mg: 17.2 (18.6) mg on maintenance and 28.4 (20.6) mg on bursts. The overall annual severe exacerbations rate during the 12-month baseline period was 2.05 per patient-year and 1.5 per patient-year over the 6-month follow-up, and frequency of hospitalizations and emergency department visits were similar on both maintenance and bursts use. Conclusions: Results show a suboptimal control of severe asthma despite such high doses of OCS and persistence of disease burden regardless of the prescribing pattern in maintenance or bursts. There is therapeutic inertia to continue using OCS despite the increased risk of adverse effects and the availability of biologics.

Short- and long-term oral steroid therapy in patients with asthma exacerbation

Steroids are frequently used for symptom control in cases of asthma exacerbation. The aim of this study was to compare the effect of short-term and long-term oral steroid therapy on symptom control in patients with asthma exacerbation. Patients that received short-term (<10 d) and long-term (≥10 d) oral steroid therapy during asthma exacerbation were compared retrospectively. A visual analog scale (VAS) for symptom severity was administered, and the asthma control test (ACT) and pulmonary function tests were performed before and after treatment. The study included 69 patients and the overall mean duration of steroid treatment was 9.57±3.58 d (range: 5-25 d). Mean duration of short-term and long-term steroid treatment was 6.54±0.99 d and 11.63±3.21 d, respectively. Serious side-effects were not observed following oral steroid therapy. Post the short- and long-term oral steroid therapy there were not any significant differences between the 2 groups in terms of ACT, FEV1 (forced expiratory volume 1), or VAS symptom scores. The findings show that in patients with mild asthma exacerbation short-term oral steroid therapy is as effective as long-term steroid therapy and can be safely used for symptom control during periods of mild asthma exacerbation.

Improving Care in Eosinophil-Associated Diseases: A Charter

Eosinophil-associated diseases (EADs) are a range of heterogeneous conditions in which eosinophils are believed to play a critical pathological role. EADs include common illnesses such as eosinophilic asthma and chronic rhinosinusitis and rare conditions such as hypereosinophilic syndromes (HES) and eosinophilic gastrointestinal disorders (EGIDs). EADs are associated with substantial burdens for the patient, including chronic, debilitating symptoms, increased financial burden, decreased health-related quality of life, and the need for repeated visits to multiple different healthcare professionals (HCPs), emergency departments, and/or hospitals. Poor EAD recognition by HCPs often contributes to delayed diagnoses, which further delays patient access to appropriate care and effective treatments, contributing to poor health outcomes. The objective of this charter is to outline key patient rights and expectations with respect to the management of their condition(s) and to set forth an ambitious action plan to improve health outcomes for patients with EADs: (1) people with EADs, their caretakers, HCPs, and the public must have greater awareness and education about EADs; (2) people with EADs must receive a timely, accurate diagnosis; (3) all people with EADs must have access to an appropriate multidisciplinary team, when necessary; and (4) people with EADs must have access to safe and effective treatment options without unnecessary regulatory delays. The principles described in this charter demonstrate the core elements of quality care that people with EADs must receive, and they represent clear steps by which to reduce patient and caregiver burden and improve patient outcomes. We urge HCPs, healthcare systems, and policymakers worldwide to swiftly adopt these principles to ensure patients with EADs have an accurate diagnosis in a timely manner and access to high-level care and treatment in an appropriate setting.

Current unmet needs and potential solutions to uncontrolled asthma

Despite the availability of effective inhaled therapies, many patients with asthma have poor asthma control. Uncontrolled asthma presents a significant burden on the patient and society, and, for many, remains largely preventable. There are numerous reasons why a patient may remain uncontrolled despite access to therapies, including incorrect inhaler technique, poor adherence to treatment, oversight of triggers and suboptimal medical care. Shared decision-making, good patient-clinician communication, supported self-management, multidisciplinary patient education, new technology and risk stratification may all provide solutions to this major unmet need in asthma. Novel treatments such as biologics could benefit patients' lives, while the investigations into biomarkers, non-Type 2 asthma, treatable traits and disease modification give an exciting glimpse into the future of asthma care.

Reducing Tolerance for SABA and OCS towards the Extreme Ends of Asthma Severity

Asthma is a heterogeneous chronic inflammatory airway disease that imposes a great burden on public health worldwide. In the past two years, fundamental changes have been addressed in the Global Initiative for Asthma (GINA) recommendations focusing mainly on the management of mild and severe asthma. The use of as-needed treatment containing inhaled corticosteroids plus fast-acting bronchodilators (either short or long-acting formoterol) in mild asthma has dominated the field, and both randomized and real-world studies favor such an approach and associate it with fewer exacerbations and good asthma control. At the same time, the effort to diminish the use of oral steroids (OCS) as maintenance treatment in severe asthma was substantially accomplished with the initiation of treatment with biologics. Still, these options are available at the moment only for severe asthmatics with a T2-high endotype, and relevant studies on biologics have yielded, as a primary outcome, the reduction or even cessation of OCS. Accordingly, OCS should be considered as a temporary option, mainly for the treatment of asthma exacerbations, and as a maintenance treatment only for a minority of patients with severe asthma, after ensuring good inhaler technique, modification of all possible contributory factors and comorbidities, and optimized pharmacotherapy using all other add-on treatments including biologics in the armamentarium of anti-asthma medication.

A Systematic and Critical Review of Discrete Choice Experiments in Asthma and Chronic Obstructive Pulmonary Disease

Background

Regulators have called for greater emphasis on the role of the patient voice to inform medical product development and decision making, and expert guidelines and reports for asthma and chronic obstructive pulmonary disease (COPD) both explicitly recommend the consideration of patient preferences in the management of these diseases. Discrete choice experiments (DCEs) are commonly used to quantify stakeholders’ treatment preferences and estimate the trade-offs they are willing to make between outcomes such as treatment benefits and risks.

Objective

The aim of this systematic literature review is to provide an up-to-date and critical review of DCEs published in asthma and COPD; specifically, we aim to evaluate the subject of preference studies conducted in asthma and COPD, what attributes have been included, stakeholders’ preferences, and the consistency in reporting of instrument development, testing and reporting of results.

Methods

A systematic review of published DCEs on asthma and COPD treatments was conducted using Embase, Medline and the Cochrane Database of Systematic Reviews. Studies were included if they included a DCE conducted in a relevant population (e.g. patients with asthma or COPD or their caregivers, asthma or COPD-treating clinicians, or the general population), and reported quantitative outcomes on participants’ preferences. Study characteristics were summarised descriptively, and descriptive analyses of attribute categories, consistency in reporting on key criteria, and stakeholder preferences were undertaken.

Results

A total of 33 eligible studies were identified, including 28 unique DCEs. The majority (n = 20; 71%) of studies were conducted in a patient sample. Studies focused on inhaler treatments, and included attributes in five key categories: symptoms and treatment benefits (n = 23; 82%), treatment convenience (n = 19; 68%), treatment cost (n = 17; 61%), treatment risks (n = 13; 46%), and other (n = 10; 36%). Symptoms and treatment benefits were the attributes most frequently ranked as important to patients (n = 26, 72%), followed by treatment risks (n = 7, 39%). Several studies (n = 9, 32%) did not qualitatively pre-test their DCE, and a majority did not report the uncertainty in estimated outcomes (n = 18; 64%).

Conclusions

DCEs in asthma and COPD have focused on treatment benefits and convenience, with less evidence generated on participants’ risk tolerance. Quality criteria and reporting standards are needed to promote study quality and ensure consistency in reporting between studies.

Association of Oral Corticosteroid Bursts With Severe Adverse Events in Children

IMPORTANCE

The adverse effects from the long-term use of oral corticosteroids are known, but, to our knowledge, few studies have reported the risk of corticosteroid bursts, particularly among children.

OBJECTIVE

To quantify the associations of corticosteroid bursts with severe adverse events, including gastrointestinal (GI) bleeding, sepsis, pneumonia, and glaucoma, in children.

DESIGN, SETTING, AND PARTICIPANTS

This study used data derived from the National Health Insurance Research Database in Taiwan from January 1, 2013, to December 31, 2017, on children younger than 18 years of age and used a self-controlled case series design. Data were analyzed from January 1 to July 30, 2020.

EXPOSURE

Oral corticosteroid bursts (defined as oral corticosteroid use for ≤14 days).

MAIN OUTCOMES AND MEASURES

Incidence rates were calculated of 4 severe adverse events (GI bleeding, sepsis, pneumonia, and glaucoma) in children who did or did not receive corticosteroid bursts. Conditional fixed-effect Poisson regression was used to estimate incidence rate ratios (IRRs) of severe adverse events within 5 to 30 days and 31 to 90 days after initiation of corticosteroid bursts.

RESULTS

Among 4 542 623 children, 23% (1 064 587; 544 268 boys [51.1%]; mean [SD] age, 9.7 [5.8] years) were prescribed a single corticosteroid burst. The most common indications were acute respiratory tract infections and allergic diseases. The incidence rate differences per 1000 person-years between children administered a single corticosteroid burst and those not prescribed corticosteroids were 0.60 (95% CI, 0.55-0.64) for GI bleeding, 0.03 (95% CI, 0.02-0.05) for sepsis, 9.35 (95% CI, 9.19-9.51) for pneumonia, and 0.01 (95% CI, 0.01-0.03) for glaucoma. The IRRs within 5 to 30 days after initiating corticosteroid bursts were 1.41 (95% CI, 1.27-1.57) for GI bleeding, 2.02 (95% CI, 1.55-2.64) for sepsis, 2.19 (95% CI, 2.13-2.25) for pneumonia, and 0.98 (95% CI, 0.85-1.13) for glaucoma; the IRRs within the subsequent 31 to 90 days were 1.10 (95% CI, 1.02-1.19) for GI bleeding, 1.08 (95% CI, 0.88-1.32) for sepsis, 1.09 (95% CI, 1.07-1.11) for pneumonia, and 0.95 (95% CI, 0.85-1.06) for glaucoma.

CONCLUSIONS AND RELEVANCE

This study suggests that corticosteroid bursts, which are commonly prescribed for children with respiratory and allergic conditions, are associated with a 1.4- to 2.2-fold increased risk of GI bleeding, sepsis, and pneumonia within the first month after initiation of corticosteroid therapy that is attenuated during the subsequent 31 to 90 days.

Glucocorticoid-induced myopathy in people with asthma: a systematic review

OBJECTIVES

To review the current literature on the evidence and the underlying characteristics of glucocorticoids (type, dosage, and duration) associated with myopathy in asthma.

DATA SOURCES

Four electronic databases were searched to October 19, 2020.

STUDY SELECTION

Inclusion criteria: adults or adolescents with asthma, taking systemic glucocorticoids, and measures of muscle impairments.

RESULTS

Nine studies met the eligibility criteria. The methodologic quality of most studies was fair or good. Two studies reported significantly lower inspiratory muscle function in outpatients taking daily oral glucocorticoids (≥10 mg), but one study reported no such difference. No differences was found in limb muscle strength in one study. Only 11-36% patients with acute exacerbation taking glucocorticoids intravenously suffered from limb muscle weakness during/after critical care admissions. Two studies reported significant associations between dosage of oral glucocorticoid use and inspiratory and limb muscle function, whereas seven studies did not find any significant correlations among the characteristics of systemic glucocorticoids and myopathy. Two studies comparing people with non-glucocorticoid dependent asthma taking inhaled glucocorticoid and healthy people did not find any significant differences in their inspiratory muscle strength and endurance.

CONCLUSIONS

There were limited studies and inconsistent results on glucocorticoid-induced myopathy in people with asthma, and its association with the characteristics of glucocorticoids use. We recommended future studies should use a commonly accepted operational definition of myopathy, utilize a cohort study design, measure the cumulative dosage of glucocorticoids, and integrate possible confounding factors in the analysis.

Eosinophil Knockout Humans: Uncovering the Role of Eosinophils Through Eosinophil-Directed Biological Therapies

The enigmatic eosinophil has emerged as an exciting component of the immune system, involved in a plethora of homeostatic and inflammatory responses. Substantial progress has been achieved through experimental systems manipulating eosinophils in vivo, initially in mice and more recently in humans. Researchers using eosinophil knockout mice have identified a contributory role for eosinophils in basal and inflammatory processes and protective immunity. Primarily fueled by the purported proinflammatory role of eosinophils in eosinophil-associated diseases, a series of anti-eosinophil therapeutics have emerged as a new class of drugs. These agents, which dramatically deplete eosinophils, provide a valuable opportunity to characterize the consequences of eosinophil knockout humans. Herein, we comparatively describe mouse and human eosinophil knockouts. We put forth the view that human eosinophils negatively contribute to a variety of diseases and, unlike mouse eosinophils, do not yet have an identified role in physiological health; thus, clarifying all roles of eosinophils remains an ongoing pursuit.

Complications and Health Care Resource Utilization Associated with Systemic Corticosteroids in Children and Adolescents with Persistent Asthma

BACKGROUND:

Limited comparative data are available on the impact of systemic corticosteroid (SCS) use in children and adolescents.

OBJECTIVE:

To determine if asthmatic children and adolescents treated with SCS have a higher likelihood of developing complications versus those not receiving SCS and to examine health care resource utilization (HCRU) in this population.

METHODS:

A retrospective study of data from children and adolescents with persistent asthma retrieved from the MarketScan database, a large US health claims data set, for the period 2000 to 2017 was performed. Propensity score matching was used to pair patients in the SCS and control cohorts. For complications, SCS subgroups (≥4 or 1-3 annual prescriptions) were compared with asthmatic controls without SCS using logistic regression, and for HCRU, cohorts were compared using negative binomial regression.

RESULTS:

A total of 67,081 patients were included (SCS: 23,898; control: 43,183). The odds of having a complication were 2.9 (95% confidence interval [CI], 2.5-3.2; P < .001) and 1.6 (95% CI, 1.6-1.7; P < .001) times higher in the ≥4 and 1 to 3 SCS groups, respectively, in the first year of follow-up versus controls. For asthma-related hospitalizations, the incidence rate ratio (IRR) was 6.9 (95% CI, 5.6-8.6) and 3.1 (95% CI, 2.8-3.4) times greater in the ≥4 SCS and 1 to 3 SCS groups, respectively, versus controls; for asthma-related emergency department visits, IRR was 5.0 (95% CI, 4.4-5.6) and 2.9 (95% CI, 2.7-3.0) times greater, respectively, versus controls (all P < .01).

CONCLUSION:

Children and adolescents receiving SCS for persistent asthma have an increased risk of developing complications and have greater HCRU in the first year of follow-up versus those without SCS exposure.

Clinical factors associated with the use of dexamethasone for asthma in the pediatric emergency department

BACKGROUND

Dexamethasone is efficacious for the treatment of pediatric asthma exacerbations but is not specifically recommended by current national guidelines.

OBJECTIVES

To describe the factors associated with prescribed dexamethasone in a pediatric emergency department (PED) and upon patient discharge.

METHODS

Retrospective chart review of patients aged 2 to 18 years discharged home from a PED with a diagnostic code for asthma (J45x). Descriptive statistics are reported and binary logistic regression with generalized estimating equations was used to examine the demographic and clinical factors associated with dexamethasone use in the PED and upon discharge.

RESULTS

594 children contributed 690 visits for asthma. Two-thirds of patients received prednisone in the PED (n = 430; 62%). Among 260 children who received dexamethasone, 76% (n = 198) were prescribed a second dose for post-discharge administration. Multivariable models showed that patients triaged as most urgent had a 50% reduction in the odds of receiving dexamethasone in the PED (OR = 0.5; 95% CI = 0.28-0.87). Patients seen by a pediatrician (OR 4.2; 95%CI 2.1-8.3) and those triaged as urgent (OR 2.9; 95% CI = 1.8-7.8) were more likely to receive a single dose of dexamethasone.

CONCLUSIONS

Dexamethasone is less commonly used in the PED for asthmatic patients triaged as most urgent. Triage acuity and level of training were associated with single-dose treatment of asthma in those receiving dexamethasone. Further studies are needed to clarify the use of dexamethasone across the spectrum of asthma severity.

The effects of oral corticosteroids on lung function, type-2 biomarkers and patient-reported outcomes in stable asthma: A systematic review and meta-analysis

BACKGROUND

Several studies have investigated the physiological effect of OCS in stable asthma, however these have included heterogeneous populations and outcomes. This paper is the first to combine their results.

METHODS

We searched Medline, Embase and Web of Science databases for studies reporting the impact of OCS on FEV₁, FVC, blood eosinophils, fractional exhaled nitric oxide (FeNO), Asthma Control Questionnaire (ACQ) score or Asthma Quality Of Life Questionnaire (AQLQ) score in stable asthma. We extracted data on the correlates of OCS response.

RESULTS

61 studies, comprising 1608 patients, were included. FEV₁ was improved by 9% (95% CI: 7, 11). There were stronger increases in FEV₁ among those with a mean baseline FEV₁<60% predicted (19%, 95% CI: 13, 24). Despite these improvements, substantial residual impairment remained after treatment. Blood eosinophils were reduced by 76% (95% CI: 63, 88) with larger decreases in studies of corticosteroid-naïve patients (93%, 95% CI: 73,100). Sputum eosinophils were reduced by 89% (95% CI: 79, 98) while FeNO was decreased by 35% (95% CI: 28, 41). ACQ scores were reduced by 20% (95% CI: 11, 29). Patients with higher baseline lung function impairment, sputum eosinophils, blood eosinophils and FeNO had improved OCS response.

INTERPRETATION

OCS consistently improves lung function, reduces markers of type-2 inflammation, and alleviates asthma symptoms. However, substantial residual impairment remained following treatment and mean improvements were below the minimally important clinically difference. Patients with increased markers of type-2 inflammation are more responsive to treatment, suggesting these should be used to better target OCS use.

Association Between Oral Corticosteroid Bursts and Severe Adverse Events : A Nationwide Population-Based Cohort Study

BACKGROUND

Long-term use of oral corticosteroids has known adverse effects, but the risk from brief oral steroid bursts (≤14 days) is largely unknown.

OBJECTIVE

To examine the associations between steroid bursts and severe adverse events, specifically gastrointestinal (GI) bleeding, sepsis, and heart failure.

DESIGN

Self-controlled case series.

SETTING

Entire National Health Insurance Research Database of medical claims records in Taiwan.

PARTICIPANTS

Adults aged 20 to 64 years with continuous enrollment in the National Health Insurance program from 1 January 2013 to 31 December 2015.

MEASUREMENTS

Incidence rates of severe adverse events in steroid burst users and non-steroid users, as well as incidence rate ratios (IRRs) for severe adverse events within 5 to 30 and 31 to 90 days after initiation of steroid therapy.

RESULTS

Of 15 859 129 adult participants, 2 623 327 who received a single steroid burst were included. The most common indications were skin disorders and respiratory tract infections. The incidence rates per 1000 person-years in steroid bursts were 27.1 (95% CI, 26.7 to 27.5) for GI bleeding, 1.5 (CI, 1.4 to 1.6) for sepsis, and 1.3 (CI, 1.2 to 1.4) for heart failure. Rates of GI bleeding (IRR, 1.80 [CI, 1.75 to 1.84]), sepsis (IRR, 1.99 [CI, 1.70 to 2.32]), and heart failure (IRR, 2.37 [CI, 2.13 to 2.63]) significantly increased within 5 to 30 days after steroid therapy initiation and attenuated during the subsequent 31 to 90 days.

LIMITATION

Persons younger than 20 years or older than 64 years were not included.

CONCLUSION

Oral corticosteroid bursts are frequently prescribed in the general adult population in Taiwan. The highest rates of GI bleeding, sepsis, and heart failure occurred within the first month after initiation of steroid therapy.

Real-life experience with benralizumab during 6 months

BACKGROUND

Benralizumab is a monoclonal antibody that binds to the human interleukin-5 (IL-5) receptor (IL-5R), thereby preventing IL-5 from binding to its receptor and inhibiting differentiation and maturation of eosinophils in the bone marrow. Because of its recent marketing approval, sufficient real-life evidence is lacking to confirm the efficacy and safety data from clinical trials. The purpose of this study was to evaluate the efficacy and safety of benralizumab for the treatment of severe refractory eosinophilic asthma in a real-world cohort of patients.

METHODS

This was a cross-sectional multicentre study of consecutive patients with severe refractory eosinophilic asthma who received treatment with benralizumab during at least 6 months. Patient follow-up was performed in specialised severe asthma units.

RESULTS

A total of 42 patients were enrolled and treated with benralizumab. Asthma control, as measured by the asthma control test (ACT), improved in all patients both at 3 months of treatment compared with baseline (13.9 ± 4 vs 20.1 ± 3.7, p < 0.001) and at 6 months of treatment compared with the results obtained at 3 months (20.1 ± 3.7 vs 21 ± 2.7, p = 0.037). Similarly, the number of emergency department visits decreased both at 3 months compared with baseline (1 [IR:0.7] vs 0 [IR:0.75], p < 0.001) and at 6 months compared with the results at 3 months (0 [IR:0.75] vs 0 [IR:0], p = 0.012). Reductions in the number of oral corticosteroid cycles, percentage of corticosteroid-dependent patients, and mean daily dose of oral or inhaled corticosteroid were also evidenced. Finally, mean lung function improvement was 291 mL (p < 0.001), and FEV1% improved both at 3 months compared with baseline (64.4 ± 9.3 vs 73.1 ± 9.1, p < 0.001) and at 6 months compared to 3 months (73.1 ± 9.1 vs 76.1 ± 12, p = 0.002). Side effects were mild and did not lead to treatment discontinuation.

CONCLUSIONS

This study confirms the efficacy and safety of benralizumab in a real-life setting with improved asthma control and lung function, and a reduced oral and inhaled corticosteroid use as well as fewer emergency department visits. In addition to a rapid initial improvement, it appears that patients continue to improve during the first 6 months of treatment.

Oral Corticosteroid Treatment Patterns of Patients in the United States with Persistent Asthma

BACKGROUND

Patients with poor asthma control may receive oral corticosteroid (OCS) therapy despite the risk for adverse effects.

OBJECTIVE

We assessed OCS use frequency and treatment patterns in patients with persistent asthma in the United States (US).

METHODS

We used the IBM MarketScan Commercial Claims and Encounters, Medicare Supplemental, and Medicaid Multistate Claims research databases to identify patients from January 1, 2012, to December 31, 2017, who were ≥12 years old, met the 2-year Healthcare Effectiveness Data and Information Set criteria for persistent asthma, and were continuously enrolled ≥6 months before (baseline) and ≥24 months after (follow-up) the persistent asthma index date. Patients were classified as high OCS use (defined as ≥450 mg of OCS prescribed within a 90-day period during follow-up), low use (use OCS but not meeting high use criteria), or no OCS use.

RESULTS

We identified 435,675 patients, of whom 65% used OCS and 19% were classified as high OCS users at some point during follow-up. The annual prevalence of high OCS use ranged from 5.3% in 2013 to 7.6% in 2017. During the entire follow-up, high and low OCS users filled an average of 2.2 and 0.8 OCS prescriptions and received an average daily dosage of 2.2 and 0.3 mg, respectively. Once the patients became high OCS users, the average daily OCS dosage was relatively stable (5.1-7.1 mg) over 3 years.

CONCLUSIONS

Patients with persistent asthma in the US have substantial exposure to OCS. OCS therapy should be considered carefully to avoid associated adverse effects.

Oral corticosteroid prescription patterns for asthma in France, Germany, Italy and the UK

Oral corticosteroids (OCS) are used to manage asthma exacerbations and severe, uncontrolled asthma, but OCS use is associated with adverse effects. We aimed to describe the patterns of OCS use in the real-world management of patients with asthma in western Europe.

We used electronic medical records from databases in France, Germany, Italy and the United Kingdom from July 2011 through February 2018. Patients aged ≥12 years with an asthma diagnosis, at least one non-OCS asthma medication within ±6 months of diagnosis, and available data ≥6 months prior to and ≥90 days after cohort entry were included. High OCS use was defined as OCS ≥450 mg prescribed in a 90-day window during follow-up. Baseline characteristics and OCS use during follow-up were described overall and by OCS use status.

Of 702 685 patients with asthma, 14–44% were OCS users and 6–9% were high OCS users at some point during follow-up. Annual prevalence of high OCS use across all countries was ∼3%. High OCS users had a mean of between one and three annual OCS prescriptions, with an average daily OCS dosage of 1.3–2.2 mg. For patients who continued to meet the high-use definition, daily OCS exposure was generally stable at 5.5–7.5 mg for ≥2 years, increasing the risk of adverse effects.

Our study demonstrates that OCS use is relatively common across the four studied European countries. Data from this study may provide decisive clinical insights to inform primary care physicians and specialists involved in the management of severe, uncontrolled asthma.

This study gives a real-world snapshot of oral corticosteroid (OCS) use in western Europe, by highlighting an opportunity to shift towards corticosteroid-sparing therapies or safer alternatives that mitigate the risk of OCS-associated adverse effects http://bit.ly/3cB8kk8

Safety of Eosinophil-Depleting Therapy for Severe, Eosinophilic Asthma: Focus on Benralizumab

Eosinophils play a pivotal role in the inflammatory pathology of asthma and have been the target of new biologic treatments for patients with eosinophilic asthma. Given the central role of interleukin (IL)-5 in the eosinophil lifecycle, several therapies directed against the IL-5 pathway have been developed, including the anti-IL-5 antibodies mepolizumab and reslizumab and the IL-5 receptor α (IL-5Rα)-directed cytolytic antibody benralizumab. Eosinophil-depleting therapies represent a relatively new class of asthma treatment, and it is important to understand their long-term efficacy and safety. Eosinophils have been associated with host protection and tumor growth, raising potential concerns about the consequences of long-term therapies that deplete eosinophils. However, evidence for these associations in humans is conflicting and largely indirect or based on mouse models. Substantial prospective clinical trial and postmarketing data have accrued, providing insight into the potential risks associated with eosinophil depletion. In this review, we explore the current safety profile of eosinophil-reducing therapies, with particular attention to the potential risks of malignancies and severe infections and a focus on benralizumab. Benralizumab is an IL-5Rα-directed cytolytic monoclonal antibody that targets and efficiently depletes blood and tissue eosinophils through antibody-dependent cell-mediated cytotoxicity. Benralizumab is intended to treat patients with severe, uncontrolled asthma with eosinophilic inflammation. The integrated analyses of benralizumab safety data from the phase III SIROCCO and CALIMA trials and subsequent BORA extension trial for patients with asthma, and the phase III GALATHEA and TERRANOVA trials for patients with chronic obstructive pulmonary disease, form the principal basis for this review.

Perception of oral corticosteroids in adult patients with asthma in France

OBJECTIVE

Oral corticosteroids (OCS) are frequently used as relievers for acute asthma and controllers for severe asthma. However, the relief offered by OCS is counterbalanced by adverse effects. We aimed to describe how patients perceive OCS treatment benefits and risks, and how this could affect their adherence to the treatment.

METHODS

Patients aged ≥18 years with asthma registered with Carenity, an online patient community, were invited to respond to a questionnaire containing 35 closed and 3 open questions to assess their asthma and perceptions of OCS.

RESULTS

268/300 respondents were receiving or had received OCS for asthma (58 for long-term use and 107 for short-term use). The mean age at diagnosis was 21.3 years. 66% had uncontrolled asthma (GINA control score 3 or 4). Although 42% perceived OCS to be efficacious, 46% mentioned adverse effects. Respondents were mostly satisfied with OCS (median = 7.0/10), particularly for efficacy (median = 8.0/10). Respondents reported having strategies to avoid OCS, mainly because of adverse effects. 26% of respondents had previously reduced or stopped OCS; this proportion was 22% for short-term OCS users and 36% for long-term users. 15% of the respondents not receiving long-term OCS would take the treatment without doing anything else if long-term OCS were prescribed; 42% would seek an alternative treatment.

CONCLUSIONS

OCS for asthma is perceived efficient but associated with adverse effects. Patients seek alternative treatment.
