Filter by:This study aims to identify whether early administration of magnesium sulfate in moderate asthma exacerbations can potentially avoid admission, decrease length of stay in the emergency department (ED), decrease length of stay (LOS) in the general hospital floor vs pediatric intensive care unit (PICU), and decrease the need for respiratory support.
The purpose of this study is to evaluate dexpramipexole as an add-on oral therapy in participants with inadequately controlled eosinophilic asthma to evaluate improvements in lung function, asthma control, and quality of life. In addition, the study will further evaluate the safety and tolerability of dexpramipexole in participants with eosinophilic asthma.
After outpatient clinic visit, asthmatic patients with worsening of symptoms (including dyspnea, wheezing, chest tightness, cough, activity limitation, awaken in the midnight due to discomfort) and are diagnosed of acute exacerbation by physician, will be recruited. The patients are asked to record symptoms using asthma symptom diary (ASD) with home spirometry simultaneously for 14 days. Visit 1 (day 1) All patients will be evaluated the following: 1. Record the patients' demographics (age, gender, race), baseline characteristics, comorbidities, health care resources use (visits, lab tests, hospitalization and cost), pharmacological and non-pharmacological treatments 2. Blood sampling for eosinophils, eosinophil cationic protein (ECP) and immunoglobulin E (IgE) as clinically indicated (if no data available within one year for the last two) 3. The study assistant will introduce to the patient how to manipulate the home spirometry and its app, and to record the daily asthma symptoms by using the ASD on the mobile phone. Visit 2 (day 15) All patients will be arranged outpatient clinic follow up 2 weeks later from the first visit. The outpatient clinic physician will check the home spirometry report and ASD symptom score in the past 2 weeks, and have a well explanation of these results. Statistical analysis The usage of digital function including input ASD, and the lung function from portable spirometer in study arm will be demonstrated by descriptive statistics.
Exacerbations of asthma (asthma attacks) are very common in the UK. They are frightening for patients, expensive for the health service, and occasionally lead to avoidable deaths. Despite the obvious importance of asthma attacks, they remain poorly understood. Although some of the triggers for attacks are known, the resultant characteristics of attacks are not. Recent research has shown different inflammation profiles associated with asthma attacks; however, this is not well understood, and all asthma attacks are treated the same. Increased knowledge about the nature of asthma attacks may better define these attacks and help develop more targeted treatment options. This study aims to describe the characteristics of patients admitted with asthma attacks. The recovery and response to standard treatment for asthma attacks following discharge from the hospital will also be described. This is achieved by studying the characteristics of asthma attacks in patients hospitalized with acute asthma. Participants will be asked to attend two follow-up visits during which their response to treatment will be described. The study is planned to last for 2.5 years, with a recruitment period of 18 months, and will include 100 participants with acute asthma.
Asthma attacks which are moderate-to-severe are typically treated with corticosteroids, but the optimal treatment duration is unknown and treatment responses can be variable. Inadequate treatment may compromise recovery, but increased exposure to corticosteroids is, in turn, associated with drug-related adverse effects. There is a need for a biomarker to guide duration of corticosteroid treatment in asthma attacks. One such candidate biomarker is the blood eosinophil count, which may predict steroid-responsiveness. We hypothesize that the blood eosinophil count can potentially be used as a biomarker to guide the duration of corticosteroids in moderate-to-severe asthma attacks. This study will recruit individuals hospitalized for asthma attack. Participants will be randomized to standard care or blood-eosinophil guided systemic corticosteroid therapy. Subjects in the standard arm will receive oral corticosteroids for a total of 5 days. Subjects in the blood-eosinophil guided arm will receive oral corticosteroids for a total of 5 days if admission eosinophil count is ≥ 0.300 x 10^3/µL, and receive 3 days of oral corticosteroids if the admission blood eosinophil is < 0.300 x 10^3/µL. The rate of treatment failure will be compared between these two groups.
An observational study in patients between 12 and 70 years old with an acute asthma exacerbation, to determine the relation between phenotypical characteristics and the treatment response.
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.
The Genomics and Metagenomics of Asthma Severity (GEMAS) study aims to assess the role of genomics, the microbiome, and the interaction between them in the development of asthma exacerbations in European patients with asthma.
