Response to biologics along a gradient of T2 involvement in patients with severe asthma: a data-driven biomarker clustering approach.

Background: Asthma with low levels of T2-biomarkers is poorly understood.

Objective: To characterize severe asthma phenotypes and compare pre- to post-biologic change in asthma outcomes along a gradient of T2-involvement.

Methods: This was a registry-based, cohort study including data from 24 countries.

Biomarker profile and disease burden associated with intermittent and long-term oral corticosteroid use in patients with severe asthma prior to biologic initiation in real-life (STAR).

Background: Asthma characterization using blood eosinophil count (BEC) (among other biomarkers and clinical indices) is recommended in severe asthma (SA), but the masking effect of oral corticosteroids (OCS), makes this challenging.

Aim: Our aim was to explore the effect of OCS use (both intermittent [iOCS] and long-term [LTOCS]) prior to biologic initiation on SA phenotype and biomarker profile in real-life and to characterize the burden of SA among patients prescribed LTOCS by biomarker profile.

Methods: This was a registry-based cohort study, including data from 23 countries collected between 2003 and 2023 and shared with the Internatonal Severe Asthma Registry (ISAR).

Prevention of Cardiovascular and Other Systemic Adverse Outcomes in Patients with Asthma Treated with Biologics.

Although clinical trials have documented the oral corticosteroid (OCS)-sparing effect of biologics in patients with severe asthma, little is known about whether this translates to a reduction of new-onset OCS-related adverse outcomes. To compare the risk of developing new-onset OCS-related adverse outcomes between biologic initiators and noninitiators. This was a longitudinal cohort study using pooled data from the International Severe Asthma Registry (ISAR; 16 countries) and the Optimum Patient Care Research database (OPCRD; United Kingdom).

Impact of Biologics Initiation on Oral Corticosteroid Use in the International Severe Asthma Registry and the Optimum Patient Care Research Database: A Pooled Analysis of Real-World Data.

Background: For severe asthma (SA) management, real-world evidence on the effects of biologic therapies in reducing the burden of oral corticosteroid (OCS) use is limited.

Objective: To estimate the efficacy of biologic initiation on total OCS (TOCS) exposure in patients with SA from real-world specialist and primary care settings.

Methods: From the International Severe Asthma Registry (ISAR, specialist care) and the Optimum Patient Care Research Database (OPCRD, primary care, United Kingdom), adult biologic initiators were identified and propensity score-matched with non-initiators (ISAR, 1:1; OPCRD, 1:2).

Real World Biologic Use and Switch Patterns in Severe Asthma: Data from the International Severe Asthma Registry and the US CHRONICLE Study.

Introduction: International registries provide opportunities to describe use of biologics for treating severe asthma in current clinical practice. Our aims were to describe real-life global patterns of biologic use (continuation, switches, and discontinuations) for severe asthma, elucidate reasons underlying these patterns, and examine associated patient-level factors.

Methods: This was a historical cohort study including adults with severe asthma enrolled into the International Severe Asthma Registry (ISAR; http://isaregistries.

Global Variability in Administrative Approval Prescription Criteria for Biologic Therapy in Severe Asthma.

Background: Regulatory bodies have approved five biologics for severe asthma. However, regional differences in accessibility may limit the global potential for personalized medicine.

Objective: To compare global differences in ease of access to biologics.

Asthma Phenotyping in Primary Care: Applying the International Severe Asthma Registry Eosinophil Phenotype Algorithm Across All Asthma Severities.

Background: We developed an eosinophil phenotype gradient algorithm and applied it to a large severe asthma cohort (International Severe Asthma Registry).

Objective: We sought to reapply this algorithm in a UK primary care asthma cohort, quantify the eosinophilic phenotype, and assess the relationship between the likelihood of an eosinophilic phenotype and asthma severity/health care resource use (HCRU).

Methods: Patients age 13 years and older with active asthma and blood eosinophil count or 1 or greater, who were included from the Optimum Patient Care Research Database and the Clinical Practice Research Datalink, were categorized according to the likelihood of eosinophilic phenotype using the International Severe Asthma Registry gradient eosinophilic algorithm.

Eosinophilic and Noneosinophilic Asthma: An Expert Consensus Framework to Characterize Phenotypes in a Global Real-Life Severe Asthma Cohort.

Background: Phenotypic characteristics of patients with eosinophilic and noneosinophilic asthma are not well characterized in global, real-life severe asthma cohorts.

Research Question: What is the prevalence of eosinophilic and noneosinophilic phenotypes in the population with severe asthma, and can these phenotypes be differentiated by clinical and biomarker variables?

Study Design And Methods: This was an historical registry study. Adult patients with severe asthma and available blood eosinophil count (BEC) from 11 countries enrolled in the International Severe Asthma Registry (January 1, 2015-September 30, 2019) were categorized according to likelihood of eosinophilic phenotype using a predefined gradient eosinophilic algorithm based on highest BEC, long-term oral corticosteroid use, elevated fractional exhaled nitric oxide, nasal polyps, and adult-onset asthma.

Cluster Analysis of Inflammatory Biomarker Expression in the International Severe Asthma Registry.

Background: Allergy, eosinophilic inflammation, and epithelial dysregulation are implicated in severe asthma pathogenesis.

Objective: We characterized biomarker expression in adults with severe asthma.

Methods: Within the International Severe Asthma Registry (ISAR), we analyzed data from 10 countries in North America, Europe, and Asia, with prespecified thresholds for biomarker positivity (serum IgE ≥ 75 kU/L, blood eosinophils ≥ 300 cells/μL, and FeNO ≥ 25 ppb), and with hierarchical cluster analysis using biomarkers as continuous variables.

Evaluating the real-life effect of MP-AzeFlu on asthma outcomes in patients with allergic rhinitis and asthma in UK primary care.

Background: MP-AzeFlu (Dymista®; spray of azelastine/fluticasone propionate) is the most effective allergic rhinitis (AR) treatment available. Its effect on asthma outcomes in patients with AR and asthma is unknown.

Methods: This pre-post historical cohort study, using the Optimum Patient Care Research Database, included patients aged ≥12 years, from UK general practice with active asthma (defined as a recorded diagnosis, with ≥1 prescription for reliever or controller inhaler) in the year before or at the initiation date.

International severe asthma registry (ISAR): protocol for a global registry.

Background: Severe asthma exerts a disproportionately heavy burden on patients and health care. Due to the heterogeneity of the severe asthma population, many patients need to be evaluated to understand the clinical features and outcomes of severe asthma in order to facilitate personalised and targeted care. The International Severe Asthma Registry (ISAR) is a multi-country registry project initiated to aid in this endeavour.

Characterization of Severe Asthma Worldwide: Data From the International Severe Asthma Registry.

Background: Clinical characteristics of the international population with severe asthma are unknown. Intercountry comparisons are hindered by variable data collection within regional and national severe asthma registries. We aimed to describe demographic and clinical characteristics of patients treated in severe asthma services in the United States, Europe, and the Asia-Pacific region.

Electronic Clinical Decision Support System for allergic rhinitis management: MASK e-CDSS.

Background: Allergic rhinitis (AR) management has changed in recent years following the switch from the concept of disease severity to the concept of disease control, publication of the AR clinical decision support system (CDSS) and development of mobile health (m-health) tools for patients (eg Allergy Diary). The Allergy Diary Companion app for healthcare providers is currently being developed and will be launched in 2018. It incorporates the AR CDSS to provide evidence-based treatment recommendations, linking all key stakeholders in AR management.

The subpoena and a day in court: guidelines for nurses.

Psychiatric nurses or therapists may be subpoenaed to appear as direct or expert witnesses. The response must be carefully prepared, and nurses must be aware that testifying in court can be an anxiety-provoking experience. Testifying often involves being an advocate for a client.

Evaluation of outcomes in Psychiatric Consultation-Liaison Nursing practice.
