Filter by:Chronic obstructive pulmonary disease (COPD) is a lung disease caused by cigarette smoke that affects millions of people. In the United States, COPD is the 3rd leading cause of death making it one of our most important public health problems. Some people with COPD get disease flares that are called acute exacerbations of COPD - or AECOPDs for short. When people get an AECOPD they experience increased shortness of breath, wheezing and cough; symptoms that often require urgent or emergent treatment by healthcare providers. In the most severe, life-threatening situations, people with AECOPDs are put on a ventilator in the emergency department and admitted to the intensive care unit. Most AECOPDs can be treated with low doses of medications called steroids. This is good because high doses of steroids can cause unwanted side effects. Unfortunately, recent studies suggest that the sickest people, those admitted to the intensive care unit needing ventilator support, need higher doses of steroids because they may have resistance to these important medications. The investigators are studying steroid resistance during very severe AECOPDs so that we can eventually develop better and safer therapies for these vulnerable people.
The aim of the study is to examine if automated oxygen delivery with O2matic allows for faster weaning from oxygen and better oxygen control than manually controlled oxygen therapy for patients admitted with an exacerbation of chronic obstructive pulmonary disease (COPD). Furthermore it will be tested if O2matic compared to manual control allows for faster discharge from hospital. Patients sense of security, anxiety and dyspnea will be evaluated by questionnaires.
Chronic obstructive pulmonary disease (COPD) is a significant cause of morbidity and mortality worldwide. In contrast to other chronic diseases, COPD is increasing in prevalence and is projected to be the third-leading cause of death and disability worldwide by 2030. The costs to society for treating COPD are high, accounting for approximately 3.4% of the total health care budget of the European Union. Acute exacerbations of COPD (AECOPD) are responsible for a large portion of the economic burden of COPD. More than 500,000 hospitalisations and 100,000 deaths are attributed to AECOPD in the US each year. In addition to a substantial economic burden, AECOPD is also responsible for much of the morbidity and mortality from COPD. Interleukin-33 (IL-33) is an alarmin released from the epithelium following damage. IL-33 is an IL-1 family alarmin cytokine constitutively expressed at epithelial barrier surfaces where it is rapidly released from cells during tissue injury. IL-33 signals through a receptor complex of IL-1 receptor-like 1 (IL1RL1) (known as ST2) and IL-1 receptor accessory protein (IL1RAcP) to initiate MyD88-dependent inflammatory pathways. The role of the IL33/ST2 axis in COPD is uncertain. IL33 has been implicated in eosinophil recruitment to the airway and maturation in the bone marrow largely via its effects upon innate lymphoid cells. IL33 increased following experimental cold in asthma and thus might play a role in the consequent inflammatory response and possible susceptibility to secondary bacterial infection in obstructive lung disease. Both eosinophilic inflammation and viral infection drive COPD exacerbations and therefore targeting the IL33/ST2 axis might reduce COPD exacerbations. The main aim of this trial is to evaluate whether anti-ST2 will impact on airway inflammation in COPD and therefore reduce the frequency of exacerbations. For the purposes of this trial, exacerbations are defined as flare-ups of symptoms involving the use of healthcare resulting in treatment with steroids and/or antibiotics and/or hospitalisation or death due to COPD.
We have demonstrated for the very first time that it is possible to isolate CPCs (circulating pulmonary cells) in patients with COPD in a sample of 17 patients (with a recovery rate of nearly 40%) and none of 10 healthy, non- smokers controls with a patented method [provisional Spanish Patent Application (P201730724)], based on liquid biopsy methodology (Romero Palacios et at, submitted 2017), showing that patients with COPD and isolation of CPCs have a more severe disease (expressed as higher BODEx index) and a trend towards a higher rate of decline of lung function as well as an increased rate of exacerbations, suggesting that CPCs isolation could be of value as a diagnostic and prognostic tool identifying patients with more active diseases. However, due to the small sample, no definitive conclusions could be made. Moreover, as there were no healthy smokers included in this study, we couldn´t evaluate if CPCs could be isolated in this type of population. The fact that CPCs could be isolated in a group of patients with COPD and its relationship with greater severity suggests that this could be a marker of progression of the disease and could detect those patients more likely to benefit from newer antiinflamatory therapies(17)
The study aims to investigate if veno-venous (vv)-extracorporeal carbon dioxide Removal (ECCO2R) is capable of reducing mortality and/or severe disability at day 60 after randomisation in patients with severe acute exacerbation of chronic obstructive pulmonary disease (COPD) requiring invasive mechanical ventilation (IMV). Extubation will be facilitated by VV-ECCO2R and compared to IMV alone in a randomized controlled trial.
Rationale: Chronic Obstructive Pulmonary Disease (COPD) is a disease with high morbidity and mortality worldwide. COPD exacerbations are the important contributor to disease deterioration and decrease in health-related quality of life (HRQoL). Since therapeutic options to treat exacerbations effectively are limited, many patients have persistent loss of vital functioning and suffer from frequent re-hospitalisations. Nasal high flow therapy (nHFT) is an innovative therapy that provides humidified and heated air through a nasal cannula. Although there is some preliminary evidence that nHFT is effective in stable COPD patients, there are no data at all regarding the effectiveness of nHFT in COPD exacerbations. A key problem in the implementation of nHFT is that the underlying working mechanisms are not clear and therefore the appropriate way to apply nHFT is unknown. Objective: The aim of the present study is to prove efficacy of nHFT in enhancing recovery from COPD exacerbations. We aim to improve the effectiveness of nHFT by developing new technologies to control and monitor the effect of nHFT and by providing background for optimal settings of nHFT. Study design: The study will be designed as a multicentre randomised controlled trial, with the University Medical Center Groningen, the "Medisch Spectrum Twente", "Albert Schweizer ziekenhuis", Rijnstate hospital, and the University of Twente, collaborating. Study population: One hundred thirty-six patients with known COPD GOLD stage II to IV and hypoxemic respiratory failure hospitalised with a COPD exacerbation will be included. Intervention (if applicable): Patients will be randomised to standard care or nHFT (≥ 6 hours/day) during hospitalisation and the 90 days after discharge, as added to standard care. Main study parameters/endpoints: The primary outcome will be improvement in HRQoL after 90 days.
Readmission to hospital is one of the most important problems in chronic obstructive pulmonary disease (COPD) patients who developed chronic respiratory failure. Patients receiving long-term oxygen therapy (LTOT) and noninvasive ventilation (NIV) constitute the most vulnerable group because of the need for comprehensive care. However, because of lack of health care support systems in Turkey, many advanced COPD patients are hospitalized due to preventable problems such as insufficient knowledge about the therapies, nonadherence to therapy and technical issues related to LTOT/NIV equipment. The aim of this multicenter randomized trial is to find out whether a structured discharge and follow-up protocol reduce the rate of unplanned, COPD-related hospital readmissions over 90 days in patients receiving LTOT or NIV.
The aim of the study is to examine if automated oxygen delivery with O2matic is better than manually controlled oxygen therapy for patients admitted to hospital with an exacerbation in Chronic Obstructive Pulmonary Disease (COPD). O2matic is a closed -loop system based on continuous non-invasive measurement of pulse and oxygen-saturation that is processed in an algorithm that controls the flow of oxygen to the patient. The primary hypothesis is that O2matic increases time within acceptable oxygen-saturation interval. Secondary hypotheses are that O2matic compared to manual control reduces time with severe hypoxia (SpO2 < 85 %), hypoxi (SpO2 below intended interval) and hyperoxia (SpO2 above intended interval).
