Long-Term Effectiveness of Anti-IL4R Therapy Following Suboptimal Response to Anti-IL5/5R Therapy in Severe Eosinophilic Asthma.

BACKGROUND: Dupilumab is an anti-IL4R monoclonal antibody (mAb) with proven efficacy in severe eosinophilic asthma (SEA). A suboptimal response to anti-IL5/5R mAbs is seen in some patients with ongoing evidence of T2 inflammation. OBJECTIVE: To understand whether targeting IL-13 pathways with dupilumab in these patients may lead to better clinical outcomes. METHODS: We performed a retrospective analysis of the extended clinical effectiveness of dupilumab up to 2 years of treatment in patients with SEA who had not responded adequately to anti-IL5/5R biologics. Ability to achieve clinical remission and change in the remission domains of exacerbation rate (AER), maintenance oral corticosteroid dose (mOCS), lung function (FEV1) and asthma control (ACQ6) were recorded. RESULTS: Thirty-seven patients (mean age 41, 70% female) were included in the analysis. The mean (SD) AER fell by almost 90% from 3.16(1.28) at dupilumab initiation to 0.35(0.72) after 1 year. The median (IQR) mOCS dose (n=20) fell from 10(5-25) mg to 0 (0-5) mg at 1 year, with 14/20 (70%) able to stop prednisolone altogether. Clinical remission was achieved in 16/37 (43%). Patients who achieved remission had a higher pre-IL5/5R FeNO level (85ppb [39-198] vs 75ppb [42-96], p=0.03). CONCLUSION: Significant improvements in clinical outcomes are possible following a switch to dupilumab in patients experiencing a suboptimal response to anti-IL5/5R therapies. A higher FeNO in poor responders to anti-IL5/5R who achieve remission with dupilumab is suggestive of an IL-13 driven sub-phenotype of T2-high asthma in which the eosinophil appears unlikely to play a key role in the disease pathogenesis.

Long-Term Effectiveness of Benralizumab in Eosinophilic Granulomatosis With Polyangiitis.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic disease characterized by eosinophilic tissue inflammation. Benralizumab, an anti-IL-5 receptor (anti-IL-5R) monoclonal antibody, induces rapid depletion of eosinophils; its longer-term effect in EGPA is unknown. OBJECTIVE: To assess the real-world effectiveness and clinical remission rates of anti-IL-5R therapy in EGPA. METHODS: We performed a retrospective cohort analysis of patients with EGPA, who commenced treatment with benralizumab. Clinical remission, assessed at 1 year and 2 years after the initiation of benralizumab, was defined as an absence of active vasculitis (Birmingham Vasculitis Activity Score of 0) and an oral corticosteroid (OCS) dose of ≤4 mg/d of prednisolone. "Super-responders" were defined as patients in remission and free of any significant relapses (asthma or extrapulmonary) over the preceding 12 months. The corticosteroid-sparing capacity of benralizumab, patient-reported outcome measures, and characteristics associated with clinical remission and super-responder status were also analyzed. RESULTS: A total of 70 patients completed at least 1 year of treatment with benralizumab, of whom 53 completed 2 years. Of 70 patients, 47 (67.1%) met the definition for clinical remission at 1 year, with a similar proportion in remission at 2 years. Excluding asthma-related relapses, 61 of 70 (87.1%) patients were relapse free at 1 year, and of the 53 who completed 2 years, 45 (84.9%) were relapse free. A total of 67.9% of patients no longer needed any OCS for disease control. No significant difference was seen between antineutrophilic cytoplasmic antibody (ANCA)-positive and ANCA-negative subgroups. CONCLUSIONS: In this real-world setting of patients with EGPA, treatment with benralizumab was well tolerated and resulted in corticosteroid-free clinical remission for the majority of patients.

'The dark before the dawn': the 2021 British Thoracic Society Audit of the treatment of tobacco dependency in acute trusts.

Smoking remains the single largest cause of preventable death, disability and health inequality. Smoking tobacco directly contributes to over 500 000 hospital admissions each year, making hospitals an important location to optimise treatment for tobacco dependency. The third British Thoracic Society Tobacco Dependency Audit was undertaken to determine how effectively national standards for treating tobacco-dependent smokers have been implemented and assess if any progress has been made from previous audits. Data on 14579 patients from 119 hospitals revealed 21% of patients were current smokers, 45% were offered very brief advice and 5% prescribed combination nicotine replacement therapy or varenicline. Only 9% completed a consultation with a specialist tobacco dependency practitioner during their inpatient stay and fewer than 1% of smokers were abstinent at 4 weeks following discharge. Clinical leadership of tobacco dependency services was deficient, and staff were ill equipped in supporting current smokers in their efforts to quit with only 50% of trusts offering regular smoking cessation training. There has been little meaningful improvement from previous audits and there remains woefully inadequate provision of tobacco dependency treatment for patients who smoke. The National Health Service (NHS) Long Term Plan has committed substantial, new funding to the NHS to ensure every patient that smokes admitted to hospital will be offered evidence-based support and treatment for tobacco dependency. The findings of this audit highlight the urgency with which this programme must be implemented to tackle the greatest cause of premature death in the UK and to achieve the wider well-recognised benefits for the healthcare system.

Learning digital skills online: empowering older adults through one-to-one, online digital training provision.

Introduction: Digital exclusion, through lack of access and poor digital skills, can have an adverse impact on daily living. Not only did the COVID-19 pandemic dramatically impact the necessity of technology in our daily lives, but also reduced the availability of digital skills programmes. This study aimed to explore perceived facilitators and barriers of a digital skills programme that was delivered remotely (online) and to reflect on this form of training as a possible alternative to traditional face-to-face models. Methods: Individual interviews were carried out with programme participants and the programme instructor. Results: Two themes were generated from this data: (a) Creating a unique learning environment; and (b) Encouraging further learning. Discussion: Barriers to digital delivery were evident, however, the individual and personalized delivery empowered participants within their own learning, supporting individuals to learn skills relevant to them and to continue their digital learning journey.

Progress towards enhanced access and use of technology during the COVID-19 pandemic: A need to be mindful of the continued digital divide for many rural and northern communities.

The COVID-19 pandemic produced unprecedented adoption and deployment of technology in rural and northern areas; however, this expansion widened the digital divide for many. Evidence shows that older adults' use of technology has increased. Coupled with an increasing number of available technologies to enhance healthcare delivery, social engagement, meaningful activities, and support to carers, we are at a crossroads for change. Emerging strategies used by organizations to promote technology and support efforts to bridge and close the digital divide are discussed. In a post-pandemic society, policy-makers can play a critical role to ensure that improvements, efficiency gains, and lessons learned are fully leveraged to reap the benefits of technology use by older adults, care partners, and the healthcare system. Recommendations are given for policy-makers to capitalize on this opportunity to narrow the digital divide for those in rural and northern communities.

What Role Does Geragogy Play in the Delivery of Digital Skills Programs for Middle and Older Age Adults? A Systematic Narrative Review.

This systematic narrative review aimed to explore the implementation and delivery of digital skills programs for middle and older age adults; and understand the presence of adult learning theory (namely, geragogy/critical geragogy) in their delivery. A database search was undertaken to examine international literature, published between 2010 and 2020. From 1,713 papers identified during the database searches, 17 papers were included. Thematic synthesis was used to analyze the papers in this review. Themes were generated relating to the implementation and delivery of digital skills programs: negative perceptions of aging; the learning environment; and value of technology. The role of geragogy/critical geragogy is not explicit in the delivery of digital skills programs in this review but has an underlying thread of empowerment and embodies the ethos of these learning theories to some extent. The findings of this review have been used to develop recommendations for delivering digital skills to older adults.

Increased risk of death in COVID-19 hospital admissions during the second wave as compared to the first epidemic wave: a prospective, single-centre cohort study in London, UK.

BACKGROUND: The second coronavirus disease (COVID-19) epidemic wave in the UK progressed aggressively and was characterised by the emergence and circulation of variant of concern alpha (VOC 202012/01). The impact of this variant on in-hospital COVID-19-specific mortality has not been widely studied. We aimed to compare mortality, clinical characteristics, and management of COVID-19 patients across epidemic waves to better understand the progression of the epidemic at a hospital level and support resource planning. METHODS: We conducted an analytical, dynamic cohort study in a large hospital in South London. We included all adults (≥ 18 years) with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who required hospital admission to COVID-19-specific wards between January 2020 and March 2021 (n = 2701). Outcome was COVID-19-specific in-hospital mortality ascertained through Medical Certificate Cause of Death. RESULTS: In the second wave, the number of COVID-19 admissions doubled, and the crude mortality rate dropped 25% (1.66 versus 2.23 per 100 person-days in second and first wave, respectively). After accounting for age, sex, dexamethasone, oxygen requirements, symptoms at admission and Charlson Comorbidity Index, mortality hazard ratio associated with COVID-19 admissions was 1.62 (95% CI 1.26, 2.08) times higher in the second wave. CONCLUSIONS: Although crude mortality rates dropped during the second wave, the multivariable analysis suggests a higher underlying risk of death for COVID-19 admissions in the second wave. These findings are ecologically correlated with an increased circulation of SARS-CoV-2 variant of concern 202012/1 (alpha). Availability of improved management, particularly dexamethasone, was important in reducing risk of death.

A Study to Investigate the Prevalence of Device-Specific Errors in Inhaler Technique in Adults With Airway Disease (The SCORES Study): Protocol for a Single Visit Prevalence Study.

BACKGROUND: It is a recurring theme in clinical practice that patients using inhaled medications via an inhaler do not use their device to a standard that allows for optimum therapeutic effect, and some studies have shown that up to 90% of people do not use their inhalers properly. Observation and correction of the inhaler technique by health care professionals is advised by both national and international guidelines and should be performed at every opportunity to ensure that the optimum inhaler technique is achieved by the user. This study will provide a greater understanding of the most frequent technique errors made by people using 13 different inhaler types. OBJECTIVE: This study aims to identify and compare inhaler technique errors and their prevalence in adults, using device-specific checklists in accordance with manufacturers' guidelines, for 13 specific inhaler types across all lung conditions and to correlate these errors with possible determinants of poor technique. It also aims to assess the error frequency at each step in the device-specific questionnaires and compare the error rates among device types. METHODS: In a single visit, participants using an inhaler included in the inclusion criteria will have their inhaler technique observed using an identical placebo device, which will be recorded using device-specific checklists, and technique-optimized, or switched to a suitable inhaler. RESULTS: The study is already underway, and it is anticipated that the results will be available by 2022. CONCLUSIONS: The SCORES (Study to Investigate the Prevalence of Device-Specific Errors in Inhaler Technique in Adults With Airway Disease) study will ascertain the prevalence of device-specific inhaler technique errors at each step in the device-specific checklists, compare error rates among 13 device types, and correlate these errors with possible determinants of poor technique. Future work will involve the clarification and classification of these errors into critical and noncritical categories.

The VICTORY (Investigation of Inflammacheck to Measure Exhaled Breath Condensate Hydrogen Peroxide in Respiratory Conditions) Study: Protocol for a Cross-sectional Observational Study.

BACKGROUND: More than 7% of the world's population is living with a chronic respiratory condition. In the United Kingdom, lung disease affects approximately 1 in 5 people, resulting in over 700,000 hospital admissions each year. People with respiratory conditions have several symptoms and can require multiple health care visits and investigations before a diagnosis is made. The tests available can be difficult to perform, especially if a person is symptomatic, leading to poor quality results. A new, easy-to-perform, point-of-care test that can be performed in any health care setting and that can differentiate between various respiratory conditions would have a significant, beneficial impact on the ability to diagnose respiratory diseases. OBJECTIVE: The objective of this study is to use a new handheld device (Inflammacheck) in different respiratory conditions to measure the exhaled breath condensate hydrogen peroxide (EBC H2O2) and compare these results with those of healthy controls and with each other. This study also aims to determine whether the device can measure other parameters, including breath humidity, breath temperature, breath flow dynamics, and end tidal carbon dioxide. METHODS: We will perform a single-visit, cross-sectional observational study of EBC H2O2 levels, as measured by Inflammacheck, in people with respiratory disease and volunteers with no known lung disease. Participants with a confirmed diagnosis of asthma, chronic obstructive pulmonary disease, lung cancer, bronchiectasis, pneumonia, breathing pattern disorder, and interstitial lung disease as well as volunteers with no history of lung disease will be asked to breathe into the Inflammacheck device to record their breath sample. RESULTS: The results from this study will be available in 2022, in anticipation of COVID-19-related delays. CONCLUSIONS: This study will investigate the EBC H2O2, as well as other exhaled breath parameters, for use as a future diagnostic tool.

An Evaluation of Agreement of Breathing Rates Measured by a Novel Device, Manual Counting, and Other Techniques Used in Clinical Practice: Protocol for the Observational VENTILATE Study.

BACKGROUND: Respiratory rate (RR) is the most sensitive physiological observation to predict clinical deterioration on hospital wards, and poor clinical monitoring has been highlighted as a primary contributor to avoidable mortality. Patients in intensive care have their RR monitored continuously, but this equipment is rarely available on general hospital wards. OBJECTIVE: The primary objective is to assess the accuracy of the RespiraSense device in comparison with other methods currently used in clinical practice. The secondary objective is to assess the accuracy of the RespiraSense device in participants in different positions and when reading aloud. METHODS: A single-center, prospective observational study will investigate the agreement of the RespiraSense device as compared with other device measurements (capnography, electrocardiogram) and the current standard measurement of RR (manual counting by a trained health care professional). The different methods will be employed concurrently on the same participant as part of a single study visit. RESULTS: Recruitment to this study has not yet started as funding decisions are still pending. Therefore, results are not available at this stage. It is anticipated that the data required could be collected within 2 months of first recruitment to the study and data analysis completed within 6 months of the study start date. CONCLUSIONS: The Evaluation of Agreement of Breathing Rates Measured by a Novel Device, Manual Counting, and Other Techniques Used in Clinical Practice (VENTILATE) study will provide further validation of the use of the RespiraSense device in subjects with abnormal respiratory rates.

Rare case of thoracic endometriosis presenting with lung nodules and pneumothorax.

We present the case of a 34-year-old Nigerian woman who was referred to the Respiratory team with a 12-month history of breathlessness. She was concurrently being investigated for an abdominal mass and rectal and vaginal bleeding. Consequently, she underwent cross-sectional imaging of her chest, abdomen and pelvis, revealing a small right-sided pneumothorax and right lower lobe pleural-based lesion. Shortly thereafter, she was admitted to the hospital with chest pain and required chest drain insertion. This partially treated her pneumothorax but she required referral to a cardiothoracic centre for definitive diagnosis and to manage her non-resolving pneumothorax. Biopsies from the video-assisted thoracoscopic surgery confirmed the very rare diagnosis of thoracic endometriosis.
