Objectives: The healthcare burden of moderate asthma is not as well studied as severe asthma. This study used 2019 US claims data to characterize patients in Global Initiative for Asthma (GINA) steps 3 to 5 (moderate to severe) during the first 90 days of 2019.
Methods: Patient characteristics, healthcare resource utilization and costs were described for all patients and GINA groups.
Purpose: To inform effective management strategies for severe asthma in China, this study aimed to comprehensively characterize clinical characteristics, treatment patterns, disease control status, and healthcare resource utilization among patients on GINA Step 4/5 therapies by analyzing data from the Adelphi Asthma Disease Specific Program conducted in China.
Patients And Methods: All information was retrieved from medical records or collected from physicians and patients on the survey date (August-December 2018); no follow-up was conducted. Results were summarized descriptively for patients on GINA Step 4/5 therapies, who were pooled from a consecutive sample (comprising three or more consecutive patients with physician-diagnosed asthma from each participating physician) and an oversample (comprising the next two patients with physician-perceived severe asthma from each participating physician).
Purpose: To inform better asthma management in China, this study aimed to comprehensively investigate clinical characteristics, treatment patterns, asthma control status, exacerbations, and humanistic burden among adult patients seeking hospital-based asthma care by analyzing data from Adelphi Asthma Disease Specific Program conducted in China.
Patients And Methods: All information was collected on survey date (August-December 2018) from medical records, physicians, or patients, without follow-up being conducted. Results are summarized descriptively for the overall population as well as subgroups defined by GINA 2018 treatment step.

In this letter to the editor, we present questionnaire-based data assessing the patient journey of adults with moderate-severe Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in the USA and five European countries. These data highlight how long and difficult the patient journey with CRSwNP can be and how improved disease awareness among physicians could lead to more timely diagnosis and treatment, and hence improved management of patients.

The unified airway hypothesis proposes that upper and lower airway diseases reflect a single pathological process manifesting in different locations within the airway. Functional, epidemiological, and pathological evidence has supported this well-established hypothesis for some time. However, literature on the pathobiologic roles/therapeutic targeting of eosinophils and IL-5 in upper and lower airway diseases (including asthma, chronic rhinosinusitis with nasal polyps [CRSwNP], and nonsteroidal anti-inflammatory drug-exacerbated respiratory disease) has recently emerged.
View Article and Find Full Text PDFObjectives: To characterise the real-world burden of chronic rhinosinusitis with nasal polyps (CRSwNP) in the UK, stratified by number of surgeries.
Design: Retrospective cohort study.
Setting: UK Clinical Practice Research Datalink Aurum database with Hospital Episodes Statistics linkage (2007-2019).
Objective: To characterize healthcare burden, treatment patterns, and clinical characteristics associated with chronic rhinosinusitis with nasal polyps (CRSwNP).
Study Design: Retrospective cohort.
Setting: Real-world study using US health insurance claims database.
Background: Patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) often require repeat sinus surgery. Mepolizumab reduced the need for sinus surgery in the SYNAPSE trial; this analysis sought to provide a more in-depth assessment of surgery endpoints in SYNAPSE.
Methods: SYNAPSE was a double-blind Phase III trial (NCT03085797) in adults with recurrent, refractory, severe, CRSwNP eligible for repeat sinus surgery despite standard of care treatments and previous surgery.
Introduction: Acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) are important clinical events, with many patients experiencing multiple AECOPDs annually. The terms used in the literature to define recurring AECOPD events are inconsistent and may impact the ability to describe the true burden of these events. We undertook a systematic review to identify and summarize terms and definitions used in observational studies to describe AECOPD-related events occurring after an initial AECOPD (hereafter "subsequent AECOPD").

We describe EOS distributions and ranges published in asthma, COPD, control (non-asthma/COPD) and general populations.
Methods: We conducted a comprehensive literature review and meta-analysis of observational studies (January 2008 to November 2018) that included EOS counts in asthma, severe asthma, COPD, control and general populations.
Objective: To identify phenotypic factors associated with the Short Physical Performance Battery (SPPB) and its individual sub-tests: standing balance, 4‑meter gait speed (4mGS) and 5-repetition sit-to-stand (5STS).
Methods: The Evaluation of the Role of Inflammation in non-pulmonary disease manifestations in Chronic Airways disease (ERICA) study recruited adult participants with stable chronic obstructive pulmonary disease (COPD). Proportional odds models identified factors associated with the SPPB, and a principal component analysis (PCA) evaluated how much SPPB variance was explainable by each of its 3 sub-tests.

Purpose: To characterize and estimate the proportion of patients with chronic obstructive pulmonary disease (COPD) who continue to exacerbate while receiving triple therapy and further describe these patients according to blood eosinophil counts.
Methods: This was an analysis of the 2017 Adelphi Real-World Respiratory Disease Specific Programme (DSP) survey of patients with COPD from France, Germany, Italy, Spain, and the United Kingdom (UK). Demographics were assessed on the date of completion of the physician/patient questionnaire; clinical characteristics were captured for the previous 12 months.
Cardiovascular (CV) disease is a major cause of morbidity and mortality in chronic obstructive pulmonary disease (COPD). Patients with COPD have increased arterial stiffness, which may predict future CV risk. However, the development of arterial stiffness in COPD has not yet been studied prospectively.

The primary objective of this study was to estimate HCRU in patients with evidence of COPD with and without MW diagnosis codes.
Materials And Methods: This retrospective analysis used the MarketScan Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits databases.
: Randomized controlled trials (RCTs) often recruit patients from low and high socioeconomic status (SES) countries, but little is known about the effect of SES on clinical outcomes, particularly patient-centered measures of symptomatic benefit. : Combined individual chronic obstructive pulmonary disease (COPD) patient data from the placebo and long-acting bronchodilator arms of 17 RCTs (from the COPD Biomarkers Qualification Consortium database) were analyzed. Health status was measured using the St George's Respiratory Questionnaire (SGRQ) (minimum clinically important difference [MCID]: 4 units).
View Article and Find Full Text PDFWe aimed to estimate the usefulness of a disease specific health status measure, the St George's Respiratory Questionnaire (SGRQ), to predict outcomes in patients with chronic obstructive pulmonary disease (COPD). Individual patient-data of 12043 patients from long-term randomized clinical trials (2-4 years' duration) in the COPD Biomarkers Qualification Consortium database were analyzed. The adverse COPD outcomes were: exacerbations of COPD, hospital admissions due to exacerbation and all-cause mortality.
View Article and Find Full Text PDFThe COPD Biomarkers Qualification Consortium (CBQC) is a public-private partnership formed in 2010 with a goal of qualifying biomarkers and clinical assessment tools for use in clinical or nonclinical decision-making and particularly within the regulatory context. The St George's Respiratory Questionnaire (SGRQ) is a measure of health-related quality of life widely used in clinical research. The aim of the CBQC working group on SGRQ was to construct an individual patient level database of clinical trial data that included the SGRQ, to use this to confirm the reliability and validity of the SGRQ as an outcome measure of health status, and investigate its use as a predictor of future events (exacerbations and mortality).

Methods: Logistic regression was used to determine factors associated with GORD; Cox proportional hazards models were used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for GORD and risk of exacerbation and death.
Results: Among 2135 COPD patients from the ECLIPSE cohort, 547 patients self-reported GORD, with female preponderance; 237 were taking PPI/H2RA.
Female sex hormones are thought to affect women's risk of developing central nervous system (CNS) tumors. Some have reported an increased risk in users of menopausal hormone therapy (HT) but evidence is limited. In the UK General Practice Research Database we compared prospectively collected information on HT prescriptions in women aged 50-79 years with CNS tumors diagnosed in 1987-2011 with that in matched controls (four per case).
