The objective of this prospective observational study is to describe the epidemiological, clinical and biological characteristics of admitted patients in ICU for severe acute exacerbation of COPD, to assess the different therapeutics used, to evaluate the prognosis of patients with short, medium and long term ( 1 year) and the various factors associated with survival in ICU

NCT ID: NCT06211920 Recruiting - COPD Exacerbation Clinical Trials

Prehospital Non-invasive Ventilation for Acute Exacerbation of Chronic Obstructive Pulmonary Disease

PRENIV
Start date: December 8, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to test if treatment with prehospital Non-invasive ventilation (NIV) for patients with acute respiratory failure (ARF), due to acute exacerbation of chronic obstructive pulmonary disease (AECOPD) based on in-hospital criteria, should be used in the prehospital setting. This is performed with the introduction of prehospital arterial blood gas analyzation. The primary objective is: • To determine if early prehospital applied NIV together with standard medical treatment will affect arterial pH at hospital arrival in patients with ARF due to AECOPD. Participants in the intervention will receive Non-invasive ventilation together with standard medical treatment. The intervention will be compared to standard medical treatment alone, that may include inhaled bronchodilators, intravenous corticosteroids, and titrated oxygen supplementation.

PSV Versus ASV With Intellisync Mode for Delivery of NIV in AECOPD

PAINT-COPD
Start date: December 1, 2023
Phase: N/A
Study type: Interventional

Acute exacerbation of chronic obstructive pulmonary disease (COPD) is defined acute worsening of respiratory symptoms requiring additional therapy. COPD exacerbations affects the health status and quality of life of affected patients. The inpatient mortality during exacerbation is 3 to 4% while, intensive care unit (ICU) mortality approaches 43 to 46%. Each episode of exacerbation increases the risk of mortality subsequently(1) Non-invasive ventilation (NIV) therapy has established role in mild to moderate exacerbations of COPD. But the use of NIV therapy outside of acute exacerbation is uncertain(2) NIV use has been shown to prevent endotracheal intubation and improved hospital and ICU survival. NIV decreases the work of breathing by unloading the respiratory muscles through assisting the inspiratory phases and counterbalancing the intrinistic positive end expiratory positive pressure (ipeep)(3). NIV is delivered through face mask, although newer interfaces like helmet available(3). Tradionally pressure targeted mode is used in NIV therapy and is often given intermittently rather than continuously(4). NIV therapy via face mask was first used by Meduri et. Al in acute respiratory failure patients. Subsequent multiple randomized control trials established the role of NIV therapy in better gas exchange, reducing PCO2, reducing endotracheal intubation thereby reducing mortality, length of stay in hospital(3). NIV-PSV (pressure support ventilation) consists of 2 pressures. IPAP (inspiratory positive airway pressure) and EPAP (expiratory positive airway pressure) or PEEP. Pressure support is usually the pressure added above PEEP. Pressure support is usually started with 8-10 cm H2O to obtain a tidal volume of 6-8ml/kg ideal body weight. EPAP/PEEP is adjusted to counterbalance the iPEEP. It is usually kept at 4-6cm H2O. Fio2 is kept to maintain saturation of 88-92%. Inspiratory trigger is usually set at 1 L/min. Expiratory trigger kept at 50%. Back up rate should always be kept usually lower than the patient respiratory rate 10-12 breaths/min(5). Adaptive support ventilation (ASV) is a new method of closed loop ventilation which can switch back between pressure support and pressure control modes of ventilation. Based on the ideal body weight and % of minute volume ventilation given, the ASV mode choses the best tidal volume and respiratory rate according to the patient lung mechanics by calculating expiratory time constant (RCe) through expiratory flow volume curve(6). Since closed loop system, being a completely automated system, prevent frequent adjustment by clinician and thereby increasing the time and capacity of medical staff. The first application of such closed loop system in mechanical ventilation was done by saxton in1953 in iron lung for regulation of etCO2(7). Studies published on ASV as non-invasive mode of ventilation is limited. In a feasibility study, it has been shown that ASV can be used in non-invasive mode of ventilation with similar results to PSV in COPD patients(8).

Physiological and Environmental Data in a Remote Setting to Predict Exacerbation Events in Patients With Chronic Obstructive Pulmonary Disease

SENSOR
Start date: September 22, 2023
Phase:
Study type: Observational

The study plans to monitor around 300 people from different hospitals with COPD for a period of 3 months after they are discharged from the hospital using a smartphone app and a Fitbit device. This device can passively track certain health metrics; this way the research team can research whether it is possible to identify the early warning signs of a decline in health by using these ongoing measurements of vital signs and symptoms. This could allow doctors to intervene early and potentially prevent further deterioration in health decline and hospital admission altogether. The study seeks to investigate how similar these physiological measurements are when collected in the real world rather than just in the hospital setting, and what influence environmental factors have on a patient's health and experience of their condition.

Ferroptosis in Patients With COPD COPD With/Without Risk of Cardiovascular Events. Pathophysiological Implications, Diagnostics and Prognoses. FerrEPOC Study.

FerrEPOC
Start date: October 1, 2023
Phase:
Study type: Observational

Iron metabolism is related to several biochemical and functional factors that have a mayor impact in chronic obstructive pulmonary disease (COPD) such as hypoxia, hypercapnia, oxidative stress, chronic inflammation, cellular senescence, sarcopenia and ferroptosis. Ferroptosis is a specific form of cell death induced by excess intracellular free iron that generates lipid peroxidation of cell membranes, with subsequent cell death. The existence of excess ferroptosis in COPD due to tobacco smoke has been widely demonstrated in vitro both in respiratory tissue and in skeletal muscle. Iron and lipid metabolism disorders are an essential part of the pathogenesis of ferroptosis. These disorders have also been related to diseases that occur concomitantly with COPD, such as cardiovascular diseases. Recently, new genes related to iron metabolism that are involved in the development of ferroptosis have been identified. Proteins related with these genes have not been studied in vivo in the context of COPD and cardiovascular diseases. Some of them are purely intracellular in expression, but the expression of some of them can be measured in blood using methods available to any clinical laboratory. After an exhaustive study of the literature, we have selected a small group of circulating proteins expressed in DEGs (Differentially Expressed Genes) related to ferroptosis that overlap with the DEGs of COPD and the DEGs of atherosclerosis to evaluate the relationship between these molecules and clinical variables of COPD and their potential utility in identifying the risk of exacerbations, admissions, and cardiovascular events in COPD. This study could identify a trait in COPD useful for selecting patients at greater risk of exacerbation due to the relationship between ferroptosis and systemic inflammation and oxidative stress, cardiovascular risk and, in general, a worse prognosis of the disease. In addition, the identification of this trait can have important therapeutic implications.
