Filter by:Children with lung and airway malformations or early structural lung damage face significant challenges, often leading to recurrent respiratory infections, hospitalizations, and decreased quality of life. Despite various interventions, effective strategies are urgently needed. The link between these conditions and persistent bacterial bronchitis remains unclear, possibly due to compromised airways and reduced mucociliary clearance. Although antibiotics can alleviate symptoms, relapse is common. Experts often prescribe prophylactic azithromycin, despite limited evidence of its benefits. Azithromycin shows promise due to its anti-inflammatory and immunomodulatory effects but lacks thorough evaluation in this population. To address this gap, we propose a double-blind, randomized controlled trial to assess azithromycin's effectiveness and safety in preventing respiratory infections in children with these conditions. This research aims to inform clinical practice and improve the health of affected children and their families.
Chronic airways infection with Pseudomonas aeruginosa (PA) is associated with increased frequency of exacerbations, deterioration in quality of life and increased mortality in adult patients with bronchiectasis. Current guidelines suggest the prescription of an eradication antibiotic treatment for a first episode of PA infection (early PA infection). Several antibiotic regimens may be proposed, ranging from a monotherapy with oral fluoroquinolone (FQ) to an intravenous cotherapy with the addition of inhaled antibiotics that seems to improve the rate of PA eradication. As no study strictly favoured one regimen, current practices are heterogeneous and could certainly benefit from stronger evidence, with both medical and economic impact.
The aim of this study is to evaluate the role of procalcitonin in bronchoalveolar lavage as a biomarker for assessment of severity of non-CF bronchiectasis in children in correlation with other markers (functional and radiological severity )
As the third major chronic airway disease in China, bronchiectasis has a wide range of patients. However, the involved sites, morphological features and airway obstruction of bronchiectasis are varied, and clinical heterogeneity is high, making prognosis and severity difficult to evaluate. CT plays an important role in the diagnosis and classification of ramadasis. Based on this, we analyzed the CT findings of patients with bronchiectasis and followed up patients with bronchiectasis to understand their disease progression and prognosis, so as to further analyze the role of CT biomarkers in the type and prognosis of bronchiectasis diseases.
Bronchiectasis is a common lung disease. The Bronchiectasis Severity Index (BSI) is a widely used assessment system. The body mass index (BMI) is a commonly used measure of nutritional status, but it has its limitations. To provide a more comprehensive assessment, the investigators also consider other nutrition-related indices such as upper arm circumference, calf circumference, skinfold thickness and grip strength. The investigators will specify the relationship between nutritional status and disease progression by measuring nutrition-related indicators and tracking participants' disease progression.
Background: Some health conditions make breathing difficult and uncomfortable. When this happens every day, it is called chronic breathlessness. Over 3 million people living with heart and lung disease have chronic breathlessness in the UK. Breathlessness is very difficult for patients themselves and their families, resulting in disability and feelings of fear, distress, and isolation. Due a to lack of supportive breathlessness services many patients frequently attend hospital Accident and Emergency (A&E) departments seeking help. Given the on-going challenges faced by the National Health Service (NHS) in the United Kingdom, such as long waiting times, staff shortages, increased demand for services because of the COVID-19 pandemic, there is an urgent need to develop new ways to support those living with chronic breathlessness. One potential solution is to offer support online, as it is estimated that in the UK, 7 out of every 10 people with chronic breathlessness are internet users. With the help of patients and NIHR funding the research team lead by Dr Charles Reilly, developed an online breathlessness supportive website called SELF-BREATHE. SELF-BREATHE provides information and self-management tools such as breathing exercises, that patients can do at home themselves. SELF-BREATHE has been tested as part of its development. SELF-BREATHE is acceptable and valued by patients. But what is unknown is whether SELF-BREATHE improves patients' breathlessness and their life? This is the question this research seeks to answer. Aims 1. To test if using SELF-BREATHE for six-weeks improves patients' breathlessness, their quality of life and whether SELF-BREATHE should be offered within the NHS 2. To see if patients opt to continue to use SELF-BREATHE after six-weeks and what benefits this may have for patients. Methods The research team are undertaking a randomised controlled trial. For this, 246 people living with chronic breathlessness will be recruited in to this study. Each person will be randomly chosen by a computer to continue with their usual care or their usual care plus access to SELF-BREATHE. All study participants will complete questionnaires at the start of the study, thereafter at seven and twelve weeks after randomisation. These questionnaires will ask patients about 1) their breathlessness and its effect on their life and 2) planned and unplanned hospital visits. At the end of the study, we will compare answers to these questionnaires between the two groups at seven and 12 weeks. This will tell if SELF-BREATHE improved patients' breathlessness and reduced their need for unplanned hospital visits e.g., A&E attendances due to breathlessness.
Safety and efficacy of local instillation of Gentamicin and dexamethasone in acute exacerbation of bronchiectasis in mechanically ventilated patients
This is the follow-up study of autologous transplantation of P63+ lung progenitor cells (LPCs) for treatment of bronchiectasis (NCT03655808). Bronchiectasis is the consequence of chronic suppurative inflammation and fibrosis of the bronchial tubes and the surrounding lung tissues. This seriously damages the muscular and elastic tissues of the bronchial walls, leading to deformation and permanent dilatation of the bronchial tubes. Histopathological damage to the patient's lungs is irremediable. However, there is no effective drug for rebuilding the damaged lung tissue structure, and thus cannot fully restore normal lung function. Lung progenitor cells, located in the basal position of the bronchial epithelium, express the P63 and Keratin-5 (KRT5) marker genes. These cells are active in division and migration, continuously generating new cells to replace other types of dead epithelial cells. They exhibit functional plasticity and can directly repair bronchial and alveolar structures. P63+ LPCs can be extracted by fibreoptic brushing and then isolated, purified and expanded on a large scale using appropriate methods. Currently, preclinical studies and some pilot clinical trials have shown that these cells can successfully repair damaged lungs, improve lung function and have a favourable safety profile. To further investigate the therapeutic mechanism of P63+ LPCs, RNA sequencing will be performed on the remaining LPCs previously transplanted back into the patients. Additionally, to confirm the existence of LPCs in the lung tissue of bronchiectasis patients, the pathological sections of lung tissue samples from patients who had received surgical resection of the lesions, will be subjected to fluorescence staining.
The goal of this observational study is to learn about the use of equipment to monitor health at home in participants who have non-cystic fibrosis bronchiectasis. The main question[s] it aims to answer are: - How acceptable participants find using home monitoring equipment. - To find out if the data collected from home monitoring can help to detect chest infections (exacerbations) before participants get symptoms they are aware of. Participants will be provided with - - a handheld spirometer to record FEV1 (lung function) - a Fitbit, or other compatible activity monitor, to record activity and heart rate - a saturation monitor that fits painlessly on the end of the finger to record oxygen levels - weighing scales to record weight - a mini freezer and pre-labelled sample containers to store a daily sputum sample. There is enough room in the freezers for samples to be brought to routine clinic visits. We will provide a cool bag and freezer packs for this. A courier collection of the samples can be arranged if necessary. Participants will be encouraged to perform lung function, activity and oxygen levels at least 4 x per week. Participants will be guided through how to set up and use each piece of equipment by the research team. The devices all connect to a smartphone app called Breathe RM (Remote Monitor,) which is free to download, via Bluetooth. Once set up using the home monitoring devices and adding notes to the app should take no more than 15 minutes per day. Participants will be asked to record in the app - - episodes of pulmonary exacerbation that require antibiotic treatment - their coughing and wellness scores daily
The goal of this clinical trial is to assess the feasibility of ceftolozane/tazobactam (C/T) administered on an outpatient parenteral antibiotic therapy programme to patients with a current infective exacerbation of bronchiectasis or cystic fibrosis related to pseudomonas aeruginosa or burkholderia cepacia spp. organisms. The main question[s] it aims to answer are: - Is C/T effective, safe, well-tolerated and able to induce clinical and microbiologic response? - What are mechanisms of antimicrobial resistance are induced by administration of C/T?
