Most asthma is allergic in origin. The purpose of this study is to better understand the airway immune response to inhaled allergens in order to identify factors that promote asthma.
Approximately 300 million people have asthma worldwide and 400,000 people died from asthma globally in 2015 (GINA Asthma). Singapore's asthma mortality and hospitalisation rates are several times higher than OECD countries. Spot Blood eosinophil count (BEC) during an acute exacerbation of asthma was a predictor of more severe respiratory failure and was associated with future acute health care utilization (HR 1.8, 95% CI 1.1-2.9, p=0.02) in a previous study conducted across 4 ICUs in Singapore. Benralizumab, an anti-IL5 receptor α monoclonal antibody causes rapid depletion of blood eosinophils and reduces asthma exacerbations when given over 12-month duration in patient with Severe Eosinophilic Asthma. However, the efficacy of Benralizumab when given during an acute exacerbation of asthma in reducing future exacerbations or severity of asthma exacerbation is relatively unexplored. A Phase 2A randomized double-blind placebo-controlled trial involving the use of one dose of the intravenous formulation of Benralizumab (0.3 mg/kg or 1.0mg/kg) in patients presenting with acute asthma exacerbation did not demonstrate difference in the proportion of subjects with >/=1 asthma exacerbation at 12 weeks when compared to placebo (33.3% vs. 38.9%; P=0.67). However, compared with placebo, Benralizumab reduced asthma exacerbation rates by 49% (3.59 vs 1.82; P=0.01) and exacerbations resulting in hospitalization by 60% (1.62 vs 0.65; P=.02) in the combined groups at 12 weeks (secondary outcomes). Benralizumab, an anti-IL5 receptor α monoclonal antibody causes rapid depletion of blood eosinophils and reduces asthma exacerbations when given over 12-month duration in patient with Severe Eosinophilic Asthma. This study aims to look at whether subcutaneous administration of Benralizumab when initiated during an acute severe asthma exacerbation and then continued over 48 weeks period can increase time to first exacerbation compared to placebo as well as other key secondary outcome such as hospital readmission and health care utilization. We hypothesise that administration of Benralizumab when initiated during an acute severe asthma exacerbation and then continued over 48 weeks period can increase time to first exacerbation compared to placebo as well as other key secondary outcome such as hospital readmission and health care utilization.
Depression is seen more often in people with asthma, and may lead to increased development and severity of asthma. This study will investigate whether children with depression and asthma have less allergic disease and less inflammation than children with asthma who do not have symptoms of depression. The study will also investigate whether the lungs of children with depression and asthma respond to an anticholinergic inhaler called ipratropium more than the lungs of non-depressed asthmatic children.
In addition to its impact on health, the COVID-19 pandemic led to increased unemployment and loss of employer-sponsored insurance coverage. Obtaining coverage can be challenging and eligibility for public programs and subsidies can be limited, and those who do not qualify can face steep premiums, high-deductibles, and high out-of-pocket costs. Disruptions to employment and insurance coverage during the pandemic threaten to negatively affect asthma care and outcomes. Our parent project, Asthma in Families Facing Out-of-pocket Requirements with Deductibles (AFFORD), found that patients with asthma may be particularly vulnerable to insurance-related cost barriers and challenges navigating health insurance. Together with the Asthma and Allergy Foundation of America (AAFA), the investigators developed an asthma chat bot to help patients with asthma navigate insurance benefits and optimize health care decisions. The chat bot is an artificial intelligence-enabled interactive online tool that can answer clinical and insurance-related questions and provide information on coverage and how to find lower-cost alternatives for asthma care. In this supplement to the AFFORD project, the investigators propose a new study to understand and address the insurance and health care cost challenges faced by patients with asthma who lose employer-sponsored coverage due to COVID-19. Our Aims are: 1) to conduct a pilot randomized controlled trial to evaluate the effectiveness and feasibility and acceptability of an insurance navigation intervention, including the chat bot, to help patients with asthma regain coverage after the loss of job-related insurance during the COVID-19 pandemic; and 2) to qualitatively explore the experiences of Aim 1 participants to understand barriers and facilitators to accessing coverage and asthma care more broadly during the COVID-19 pandemic The study hypothesis is that participants receiving the intervention will be more likely to have coverage after four months and less likely to report non-adherence to asthma medications, delayed/forgone asthma care, and financial burden than those receiving usual care. Findings will provide evidence about the effectiveness of strategies to obtain coverage and maintain access to affordable asthma care and can inform ongoing and future decision making in response to the COVID-19 pandemic and other public health and economic threats.
Nowadays, the COVID-19 epidemic causes stress not only to healthy people but also to people with unhealthy conditions. Excess psychological stress (either in quality, quantity, frequency, and/or duration) could push susceptible individuals to ultimately develop clinical asthma. Depression was significantly associated with asthma interference with daily activities, breathlessness, night symptoms, use of bronchodilators, and poor compliance with medical treatment. Covid-19 pandemic induced the countries around the world to require from its citizens not to ask for health care support rather than in emergency situations and through utilizing telemedicine. This action aims to control spreading the infection with viruses as well as to reduce the workload on the healthcare providers. Although asthma is not listed as one of the chronic conditions that might complicate coronavirus infections, asthma people might have a high-stress level that might induce their asthma attack which consequentially reflects on their quality of life. People with asthma have a unique experience rather than people with other health conditions during COVID-19. Patients with asthma experience a lot of stressors that might induce asthma and impaired their HRQOL such as overuse of antiseptic substances, stay home with a sedentary lifestyle, the sudden shift to telemedicine, and electronic work from home. Also, as a result of the similarity of asthma symptoms with coronavirus symptoms, the patient might have a continuous sense of uncertainty that s/he is infected with the COVID-19 virus, and this suspicion can increase the psychological overburden on these patients. Therefore, all these stressors should be evaluated to recognize their health needs and the kind of social and health support that should be provided to them during the pandemic time. Also, Identifying the predictors of HRQOL among patients with asthma during the pandemic of COVID-19 is urgently required.
Interleukin (IL)-5 is the main cytokine responsible for the activation of eosinophils, hence therapeutic strategies have been investigated and developed for clinical use. Biologics targeting IL-5 and its receptor (first mepolizumab and subsequently, reslizumab and benralizumab), have been recently approved and used as add-on therapy for severe eosinophilic asthma resulting in a reduction in the circulating eosinophil count, improvement in lung function and exacerbation reduction in patients with severe asthma. Response to biologic therapies in severe asthma is variable, with patients being either non-responders, responders or super-responders. There is currently no explanation for this broad variation in response. It is important to examine whether these patients have distinct characteristics that could help the treating physician in making the correct diagnosis in clinical practice. Aim of this clinical study is to evaluate the efficacy of mepolizumab, a humanized IL-5 antagonist monoclonal antibody in patients with late-onset severe eosinophilic asthma with fixed obstruction and to identify the characteristics of non-responders and super-responders under mepolizumab treatment. This study is considered as non-interventional and every procedure included is happening in a clinical routine for the diagnosis and phenotyping of the asthmatic patients. Hypothesis includes the efficacy of mepolizumab treatment in late-onset severe eosinophilic asthmatic patients with fixed obstruction and relation to clinical and inflammatory biomarkers. Patients will be collected from the outpatient clinics of bronchial asthma from each site included (8 in number) which cover the whole population of Greece. Overall, this is a prospective multicenter study including eight Pulmonary Clinics. Five Pulmonary University Clinics, two of National Health System and one Army General Hospital in Thessaloniki. The study will include a screening period of up to 2 weeks to assess eligibility and obtain written informed consent, a mepolizumab treatment period of 52 weeks, once every 4 weeks, including follow up visits every 3 months during treatment. The study population will consist of 45 patients with late-onset severe eosinophilic asthma and fixed obstruction receiving mepolizumab, aged 20 and above.
