Filter by:The pathogenesis of idiopathic pulmonary fibrosis (IPF) is incompletely understood but recurrent epithelial injury occurs which evokes the coagulation cascade. Thrombin is produced as a result and is over expressed in IPF patients, so may be important in propagating disease activity. We aim to recruit patients with IPF and then complete FDG (18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose) PET (positron emission tomography) scans pre and post manipulation of the coagulation cascade to assess the role of this biological pathway in disease activity. Previous studies from our institution have demonstrated increased FDG avidity in the lungs of patients with IPF (assessed using FDG PET scans) but to date the cells and pathways responsible for this signal have not been identified and thus need further exploration.
This study will prove to concept of effectiveness of NHF in combination with a nebulizer on reversibility of lung function in COPD patients.
Static hyperinflation is frequent in Chronic obstructive pulmonary disease (COPD) , resulting in increased end expiratory lung volume and positive end expiratory pressure (PEEPi) at the end of a normal expiration. Static hyperinflation worsens the work of breathing is increases patient's dyspnea. The application of a continuous positive airway pressure (CPAP) has been shown to improve static hyperinflation and to decrease the work of breathing. Sleep is deteriorated in COPD patients, and causal factors includes static hyperinflation. The purpose of our study is to assess the effect of nocturnal CPAP on sleep quality and functional respiratory parameters.
Lung disease progression is variable among cystic fibrosis (CF) patients and depends on DNA mutations in the CFTR gene, polymorphic variations in disease-modifier genes and environmental exposure. The contribution of genetic factors has been extensively investigated, whereas the mechanism whereby environmental factors modulate the lung disease is unknown. Because these factors can affect the epigenome, investigators hypothesized that DNA methylation variations at disease-modifier genes modulate the lung function in CF patients.
Chronic Obstructive Pulmonary Disease (COPD) is a condition resulting from environmentally induced lung damage e.g. cigarette smoking and air pollution which, over time, causes individuals to suffer from symptoms including chronic cough and progressive breathlessness. In the UK COPD is predominantly caused by cigarette smoking which may have occurred decades before the symptoms appear and the disease is diagnosed. The aim of this study is to identify those COPD patients who currently have milder disease and to investigate whether a detailed, medical assessment which has time to assess all aspects of their care will improve their lung health and general wellbeing. COPD is a major cause of disability and death in the UK, with around 835,000 people currently diagnosed with the disease and an estimated further two million people who suffer from symptoms but do not yet have a diagnosis(1). Approximately 25,000 people each year die from COPD in England and Wales (2), with the disease accounting for 5.4% of all deaths in England and Wales in 2013 (3). Predominantly in its later, more severe stages, COPD causes an enormous symptom burden to patients, and accounts for up to half of emergency admissions to already overstretched hospital services in England (4). People with COPD, with a past history of smoking, are at higher risk of other medical problems such as heart disease and stroke(5). Being breathless and having multiple physical health problems can also lead to mental health problems such as anxiety and depression(5). This means it can be challenging to provide this group of people enough time to fully assess and treat all their problems, particularly due to current pressure on the length of GP appointment times. Whilst COPD is treatable, it is not curable, and emphasis on early diagnosis and intervention provided a key part of the strategy for COPD published by NHS England in 2012(6). With early diagnosis, the opportunity is provided to intervene with the aim of improving symptoms and exercise tolerance, reducing the risk of exacerbations, slowing deterioration and prolonging quality of life.
This study uses CT scans to assess airflow in the lung, the scan is quick, cheap and painless. The information from the scan may help doctors tell which patients are suitable to have surgery to cure early stage lung cancer. It may also help doctors tell which patients would benefit from surgery for emphysema and diagnose types of lung disease. The investigators will follow up patients who go through surgery to test how well the scan predicts the function of the lung after surgery. The investigators will follow patients being investigated for lung disease to test how accurate the scan is at the getting the diagnosis right.
The sequelae of tuberculosis are still the commonest causes of haemoptysis in the developing world, where life-threatening haemoptysis remains a common and not infrequently fatal medical emergency. Haemoptysis can be life-threatening either as a result of compromised gas exchange or because of circulatory collapse secondary to acute blood loss. Haemodynamic and ventilatory support, followed by bronchial artery embolisation (BAE) as a bridge to potentially curative treatment such as lung resection, remains the standard of care. Often patients do not qualify for surgical intervention and BAE is, at best, a temporary solution. External beam radiotherapy (EBRT) may be an alternative, curative intervention in the management of haemoptysis in patients with no alternative options. There is a paucity of studies reporting the use of EBRT in patients without malignancy and with regards to specific doses of EBRT. This pilot study aims to explore the potential of varying doses of EBRT in the management of massive haemoptysis.
This phase IIb randomized trial studies how well cholecalciferol (vitamin D3) supplementation works in strengthening inspiratory muscles in cholecalciferol-deficient patients with chronic obstructive pulmonary disease (COPD). Cholecalciferol supplementation may help reduce the risk of developing lung cancer and strengthen the diaphragm in cholecalciferol-deficient patients with COPD.
The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory failure is supportive and involves inhalation bronchodilators along with systemic steroids. In few cases the management of acute respiratory failure requires positive pressure ventilation (non-invasive or invasive). The use of NIV in acute exacerbation of COPD has resulted in significant reduction in morbidity and mortality. Although pressure support ventilation (PSV) allows the patient to influence the breathing pattern, ventilator-cycling criteria may worsen the patient-ventilator interaction, and severe asynchronies occur in up to 43% of patients undergoing NIV for ARF. Adaptive support ventilation (ASV) is a newer mode of ventilation that incorporates feedback mechanisms and thus provides a stable minute ventilation. We hypothesize that the use of ASV as a mode during ventilation using NIV in patients with acute exacerbation of COPD may result in reducing the duration of ventilatory support, need for intubation, and duration of intensive care unit (ICU) and hospital length of stay, when compared with PSV mode of NIV ventilation.
The purpose of this study is to assess the Respiratory Muscle Function and Neural Respiratory Drive in Interstitial Lung Disease patients.
