NCT05626777
Asthma is a common pathology, with a prevalence of 6 to 8% and more than 4 million patients in France. Its management is based on different therapeutic axes. Their use is very dependent on disease control, with therapeutic escalation, from treatment on demand to a combination of them at high dosage, according to the severe asthma's phenotype. Despite these effective therapeutic tools, there is a lack of control of the disease in the vast majority of cases, affecting at least 60% of asthmatics. Among the factors associated with lack of control, non-compliance with inhaled therapies is frequent and requires to be systematically assessed in the absence of control. Its evaluation by definition is complex and variously appreciated, fluctuating from 40 to 80%. The means proposed for evaluating it involve doctor/patient interviews, evaluation of the therapeutic response, questionnaires, evaluation of drug consumption (evaluation of number of empty boxes, integrated electronic device, withdrawal of drugs from pharmacies, etc). Asthma control is commonly evaluated using the validated Asthma Control Test score, in clinical practice and/or in research fields. An ACT score greater than 20 indicates well-controlled asthma. In addition, a change of at least 3 points is likely to indicate a clinically meaningful change in asthma control (Minimally Clinical Important Difference) in an individual patient over time and a change of 4 points or more further reduces the risk that the change is due to measurement error. In the context of severe eosinophilic asthma, Mepolizumab has shown its benefit in controlling asthma, reducing the number of exacerbations and its ability to decrease the use of oral corticosteroids (MENSA, SIRIUS). Mepolizumab is now available in 2 new "ready-to-use" forms: a pre-filled syringe and an auto-injector pen. Both systems can be administered at home either by a nurse or by the patient himself (self-administration). The choice is left to the discretion of the prescribing pulmonologist. These new possibilities of Mepolizumab administration offer greater freedom to the patient, possibly allowing him to empower himself by carrying out his own treatment, without constraint and without being dependent on the availability of a nurse or another healthcare professional qualified to inject Mepolizumab. These new methods of Mepolizumab self- administration also open the field to therapeutic non-compliance, a new problem in the field of biotherapies used for the treatment of severe asthma. The investigator hypothesize a potential therapeutic non-compliance associated with the new method of administration of Mepolizumab, with self-injection by the patient, without the assistance of a nurse. To assess this problem, the investigator propose to compare in a therapeutic trial Mepolizumab administered by pre-filled syringe by a home nurse every month versus Mepolizumab self-administered by auto-injector pen by the patient every month.
NCT05077917
The study hypothesis is that cromolyn, when combined with standard COVID-19 treatment, will improve patient symptoms and reduce the number of days to improved quality of life. Investigators will study the effects of adding cromolyn to the standard treatment of hospitalized patients with COVID-19 pneumonia and who require supplemental oxygen. Cromolyn will be administered as a nebulized treatment four times a day for four days followed by intranasal administration for two weeks. Investigators may also screen for biomarkers that could indicate inflammatory responses and treatment-induced improvement. Participants will receive either study drug or placebo which will be administered by nebulization for 4 days followed by 14 days of intranasal administration. Participants will be followed while in the hospital and then as outpatients up to day 21 following randomization.
NCT06689020
This single-center observational study aims to assess the effects of continuous high-frequency oscillation (CHFO) and continuous positive expiratory pressure (CPEP) therapy on lung recruitment using electrical impedance tomography (EIT) in spontaneously breathing patients admitted to the intensive care unit.
NCT05318482
According to actual scientific evidence, the interventions on the general population aiming at regular physical activity are one of the most efficient strategies for health improvement. Regardless of this evidence, there is a large part of the elderly population does not adhere to the recommendations of the international guidelines on daily physical activity. This is even more evident in patients with chronic respiratory and cardiological disease because exercise exacerbates existing symptoms of breathlessness. This study aims to evaluate the impact of an in-hospital motivational program dedicated to increasing physical activity. With the data of an electronic wristwatch that keeps records of movement, the health professionals incentive an increase in physical activity leading to long term behavioural changes (evaluated by the number of steps per day) in hospitalized patients with COPD and HF, which already perform a standard rehabilitation program (14 sessions).
NCT04201548
Advanced Chronic Obstructive Pulmonary Disease (COPD) is a condition with a negative prognosis that causes symptoms such as wheezing and fatigue that dramatically reduce the quality of life of the person with the disease. Typically, the advanced stage of COPD is characterized by a fluctuating pattern and recurrent hospitalizations, and by a vicious circle in which dyspnoea increases and exercise tolerance reduces, causing depression with social isolation, low quality of life and increased risk of death. Muscle dysfunction in these patients contributes together with dynamic hyperinflation to increased fatigue and dyspnoea during exercise, leading to early interruption of exertion, before reaching the maximal aerobic capacity. The European and American guidelines of the American Thoracic Society / European Respiratory Society relating to the patient with COPD emphasize the need for the patient to undergo Respiratory Rehabilitation (RR) programs. The RR should include training programs as they improve exercise capacity, dyspnoea and quality of life more than programs that do not include training. To our knowledge, no study has been performed in COPD with chronic respiratory failure (CRF) patients to evaluate the effects of High Interval Training compared to continuous submaximal training. Moreover, no different interval training protocols have been compared. However, studies conducted on healthy subjects or on other pathologies, show how the interval training protocol induces, in a specific and diversified way, physiological modifications to the cardio-respiratory and muscular systems. In COPD patients with respiratory failure with marked muscular dysfunction and associated systemic changes (systemic inflammation, vascular changes, pulmonary hypertension, right heart failure, etc.), the evaluation of the best training program would reinforce the rehabilitative indications not yet fully proposed in the Guidelines. Moreover, the evaluation of the response to different training stimuli could provide important information on the reversibility of the intolerance to the effort in this patient population. Primary aim of this study will be to evaluate the physiological effects on exercise tolerance of three training modalities performed in an intra-hospital setting (classic endurance training compared to two high-intensity interval programs - Long Interval Training and Short Interval training) in a population of COPD patients with chronic hypoxemic respiratory failure.
NCT04147013
This is a proposed randomized prospective study to evaluate both the anti-inflammatory and analgesic effects of a COX-2 inhibitor, celecoxib, in patients with aspirin-exacerbated respiratory disease and Chronic rhinosinusitis following endoscopic sinus surgery. The investigators hypothesize that supplementation with celecoxib can potentially improve surgical outcomes and reduce the postoperative usage of opioid analgesics without an increased risk of bleeding or asthma exacerbation
NCT05714527
During mechanical ventilation (MV) hypoxemic or hyperoxemic events should be carefully monitored and a quick response should be provided by the caregiver at the bedside. Pediatric mechanical ventilation consensus conference (PEMVECC) guidelines suggest to measure SpO2 in all ventilated children and furthermore to measure partial arterial oxygen pressure (PaO2) in moderate-to-severe disease. There were no predefined upper and lower limits for oxygenation in pediatric guidelines, however, Pediatric acute lung injury consensus conference PALICC guidelines proposed SpO2 between 92 - 97% when positive end-expiratory pressure (PEEP) is smaller than 10 cm H2O and SpO2 of 88 - 92% when PEEP is bigger or equal to 10 cm H2O. For healthy lung, PEMVECC proposed the SpO2\>95% when breathing a FiO2 of 21%. As a rule of thumb, the minimum fraction of inspired O2 (FiO2) to reach these targets should be used. A recent Meta-analyze showed that automated FiO2 adjustment provides a significant improvement of time in target saturations, reduces periods of hyperoxia, and severe hypoxia in preterm infants on positive pressure respiratory support. This study aims to compare the closed-loop FiO2 controller with conventional control of FiO2 during mechanical ventilation of pediatric patients
NCT03583814
The study's purpose is to evaluate the RI-Asthma Integrated Response (RI-AIR) Asthma Care Implementation Program (ACIP). RI-AIR ACIP uses an electronic information system to screen children with asthma and identify what specific services each child needs based on the child's asthma symptom and health care status. Our main goal is to see if children experience better asthma outcomes as a result of participation in the program. We will provide our intervention to 434 urban, ethnically diverse children, between 2-12 years old with asthma, and their families and evaluate whether participating in the program improves children's asthma outcomes. The second goal is to evaluate how well the program is set up and how we can make improvements to better serve families of children with asthma. The third goal is to gather information and advice from community experts so that we can make the program sustainable. Families that take part in RI-AIR ACIP will participate in the program over the course of a year, including participating in the intervention, and brief follow up visits at 3, 6, 9 and 12 months after completing the intervention. All families will complete the CASE program, which takes place over the course of about 4 weeks and involves in-school or remote school-based asthma education for school aged children, after-school or remote education sessions for their parents, asthma care training for school staff, and an evaluation of asthma triggers in the school. Families of children who have more frequent asthma symptoms and emergency healthcare visits will also compete the HARP program, a home-based program consisting of 3 home sessions (over about 6 weeks) that include individualized asthma education and strategies and supplies for controlling environmental asthma triggers. Both CASE and HARP programs are carried out by certified asthma educators and community health workers. Each child's healthcare provider (HCP) and school nurse teacher (SNT) will receive a standardized, secure email indicating the child is participating in RI-AIR. This email will include a summary of the child's baseline assessment of asthma control and prior health care use, and a description of the program. At the conclusion of the child's participation, the HCP and SNT will receive a summary by secure email summarizing the child's asthma control at the end of the intervention, services delivered, and referrals made, and for HARP participants, triggers observed in the home and supplies and referrals provided.
NCT04094818
This study will analyze gene expression and other laboratory data from biological samples collected from participants with suspected respiratory, urinary, intra-abdominal, and/or skin \& soft tissue infections; or suspected sepsis of any cause.
NCT06067191
The purpose of the study is to learn about the safety, pharmacokinetics and antiviral activity of the study medicine (RV299) for the potential treatment of respiratory syncytial virus (RSV). RSV is a highly contagious virus that can lead to serious lung infections in patients with reduced ability to fight infection. Most vulnerable populations include babies, the elderly and patients that have received a bone marrow transplant.
NCT06650917
Objective: To explore the application effect of acupoint massage combined with ear point pressing beans in the remission stage of asthma. Methods: 120 children with asthma in remission who were treated in pediatric outpatient department from January 2016 to October 2022 were randomly divided into experimental group and control group, with 60 cases in each group.The patients in both groups were treated with salmeterol and fluticasone inhalation powder once a day, twice a day. The patients in the control group were treated with acupoint massage on this basis. Acupoint massage once a day from Monday to Friday, lasting for 30 minutes each time.The patients in the experimental group were treated with ear point pressing beans on the basis of the control group. The ear point pressing beans is performed once a day from Monday to Friday. Changes in pulmonary function and asthma control were observed before and after treatment in the two groups were observed, and forced expiratory volume 1 second (FEV1),forced expiratory vital capacity (FVC), FEV1/FVC, asthma control test scale (ACT) score were compared.
NCT06011356
Aims of the study: 1. To deliver a scalable wellbeing programme to the local population of Imperial College Healthcare NHS Trust, focusing on movement. 2. To describe the natural history of long-term conditions using digital data from a smartwatch. 3. To identify digital information that is routinely collected by a smart watch that can be used to predict outcomes in patients with long term conditions. 4. To identify factors that determine whether participants engage with and improve in a movement programme. Adult patients who are registered to the Imperial NHS Care Information Exchange (CIE), an NHS patient-facing electronic health record, are eligible to participate in the study. Participants will receive a smart watch for self-monitoring of their movement and wellbeing and be asked to wear the device as much as possible. They will be asked to download a smartphone application called Connected Life, which displays movement and information on heart rate, breathing and oxygen levels to both the participant and the research team (digital data). Participants will receive secure login details for the Connected Life application from the research team, to ensure data privacy. The research team will look at participants' health records, and attempt to identify associations between the digital data and clinical information. This will allow the research team to identify digital data that predicts the onset and natural history of long term conditions, which may potentially allow for earlier diagnosis for future patients. The primary outcome of the study is the identification of trends in movement based on step-count data recorded by the smartwatch.
NCT06630078
Acute and Chronic respiratory conditions represent a leading cause of death and morbidity in children and adults worldwide. The diagnosis of bronchiolitis and asthmatic exacerbations is based on clinical, and mostly subjective, clinical parameters with moderately accurate prognostic role. Patients undergoing neck radiotherapy need invasive assessments of larynx. A simple biomarker like Voice may facilitate the management of these conditions. Recent studies showed that VOICE may be used as a good and easy biomarker to diagnose and monitor several respiratory and non-respiratory conditions. A prospective study aimed to collected VOICE and other clinical data in adults and children with common acute and chronic respiratory conditions at high impact on healthcare systems will be performed. VOICE-omic data will be linked with clinical findings generating data integration, using artificial intelligence technology to develop a Decision Support Systems to provide the basis for non-invasive personalised early recognition, diagnosis, monitoring and prognosis of patients with these conditions.
NCT04896502
The study is about comparing asthma home assessments/interventions by telemedicine compared to providing education alone. Interactive Video (IAV) defines telemedicine. It allows two-way communication in real-time with both audio and visual communication between the subject and someone from the study team. It is similar to using Face Time on a mobile device. Asthma home assessments/interventions are used to identify things in a home that can make asthma symptoms worse, called triggers. Reducing these triggers in the home can improve asthma.
NCT06096363
Right ventricular dysfunction (RVD) and right ventricular-pulmonary arterial (RV-PA) uncoupling detected by transthoracic echocardiography (TTE) in acute respiratory distress syndrome (ARDS) are associated with poor survival. Early detection of RVD and RV-PA uncoupling in patients with acute hypoxemic respiratory failure (AHRF) may be indicative of worsening and decompensating pulmonary condition which may require escalation of respiratory support. The use of TTE parameters in predicting high-flow nasal cannula (HFNC) failure has not been previously studied. The objective of this study is to identify predictors of HFNC failure by TTE and to compare its performance with the well-established ROX index.
NCT06016244
The goal of this clinical trial is to find out at which lower limit for saturation (amount of oxygen in the blood) we can best give extra oxygen to children that have been admitted for shortness of breath. We hope to accomplish a shorter period of illness for these children and that they can be discharged home earlier. Participants will receive supplemental oxygen if their blood oxygen levels are below 88% or below 92%. After admission, (parents of) participating children will fill out questionnaires. We will compare the two groups on their hospitalization duration and recovery. In other words, is it better to maintain a lower limit of 88% saturation or a lower limit of 92% in children admitted for shortness of breath?
NCT06640777
Acute Respiratory Distress Syndrome (ARDS) is a serious condition where people in hospital care suddenly have trouble breathing because of infection, pneumonia, COVID-19 or other disease. People with ARDS may have to be put in an intensive care unit (ICU) and on a ventilator to help them breathe. This trial is to try to find out if injecting a product called LEAF-4L6715 makes the treatment better or worse than what is normally given. LEAF-4L6715 is a product that contains tiny bubbles to slowly release a substance named transcrocetin which scientific studies show may increase oxygen flow and reduce inflamed cells and protect tissues of the body.
NCT06637748
Bronchial asthma is a common respiratory disorder among children, worldwide. Asthma is characterized by chronic inflammation and remodeling of the airways induced by recurrent exposure to hypoxemia that leads to repeated tissue injury and repair. The interaction between respiratory diseases and cardiovascular function is complex . Cardiac dysfunction can be attributed to pulmonary hypertension (PH) secondary to recurrent hypoxia in patients with bronchial asthma. PH affects the pulmonary vasculature by releasing various cytokines leading to pulmonary vasoconstriction and enhancing the remodeling process with muscularization and proliferation of the vascular media and intima . Other hypotheses concluded that the exaggerated respiratory efforts may raise the intrathoracic pressure and increase right ventricle (RV) afterload and consequently RV hypertrophy and/or dilatation . Children with severe bronchial asthma can experience cor pulmonale later in life, but little is known about the early cardiac changes that might be present during childhood especially for mild or moderate persistent asthma. Some studies have reported right ventricular dysfunction as the earliest hemodynamic change among those cases . Other studies did not report these results and reported impaired systolic function of the left ventricle (LV) even before diastolic dysfunction . Insufficient control of BA, in turn, can cause the formation of various pathological conditions. For example, there are studies showing the risk of cardiac arrhythmias and conduction disorders in patients with uncontrolled BA due to functional changes or pathological remodeling of the myocardium . Atrial remodeling, which is the pathomorphological basis of serious supraventricular cardiac arrhythmias, has a more rapid progression with poor BA control and is formed as a result of excessive stretching of the atrial wall, as well as other adverse factors . The connection between BA and supraventricular arrhythmias, including atrial fibrillation (AF), was noted in studies by Cepelis et al. Available data indicate that in the adult population, cardiac arrhythmias are significantly more common in patients with BA than in those without it (9). The results of a Norwegian population study HUNT study, demonstrate that the risks of supraventricular arrhythmias and AF are increased in patients with an uncontrolled BA . Electrocardiography (ECG) is the universal screening method for assessing the state of the atrial myocardium and the conducting system of the heart. According to German et al. ECG analysis can make a significant input to the assessment of the risk of formation of supraventricular rhythm and conduction disorders. Therefore, the analysis of the atrial component of the ECG, and atrioventricular conduction in patients with BA is an important component of the management of these patients, especially in pediatric practice. Consequently, the study of the characteristics of the ECG and its supraventricular component in children with BA is relevan
