Filter by:This project will use literature analysis, expert research, real-world data mining and other methods to investigate the current status of the application of antimicrobial aerosolized inhalation in healthcare institutions, combine expert recommendations and real-world data analysis results to explore potential risk points in the process of antimicrobial aerosolized drug delivery, and sort out the key points of drug use management in healthcare institutions and the key points of regulatory recommendations for healthcare institutions.
To establish a relationship between malnutrion and respiratory muscle dysfunction in patients with bronchectasis
The purpose of the project is to estimate the air temperature in the lungs after a change from room temperature (25℃) to an environment with a constant temperature of 88-92℃ in resp. lung-healthy persons and persons with bronchiectasis.
The treatment of acute exacerbation of bronchiectasis requires comprehensive treatment, and antibacterial drug therapy is the key. The study is a multicenter, randomized, evaluator-blinded, levofloxacin parallel-controlled clinical study designed to evaluate the efficacy and safety of sitafloxacin in the treatment of acute exacerbations of bronchiectasis in adults.
This observational study was designed as a prospective epidemiological screening study. Patients who applied to the centers participating in the study, bronchiectasis was detected on at least one computed tomography of the lungs; Immunoglobulin E height and/or were found to be lymphopenic on at least one examination will be included in the study. Up-to-date data will be collected from patients who have agreed to participate in the study, and a blood sample with DBS will be taken from patients. The blood taken will be subjected to analysis for ADA metabolites. For patients with a high metabolic test, the responsible researcher will advise on clarifying the diagnosis with a genetic test other than the study. In case of formation of new information for each patient, consultation will be provided by the responsible researcher. Thus, the prevalence of ADA enzyme deficiency disease in patients with bronchiectasis, Immunoglobulin E elevation and/or lymphopenia will be evaluated. In addition, with this study, it will be scientifically demonstrated whether lymphopenia and/or Immunoglobulin E height is a parameter that facilitates the early diagnosis of patients with late-onset ADA enzyme deficiency.
A 2-part multi-center, Phase 3, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy and safety of RHB-204 in adult subjects with underlying nodular bronchiectasis and documented MAC lung infection.
The primary objective of this study is to evaluate the effect of brensocatib at 10 mg and 25 mg compared with placebo on the rate of pulmonary exacerbations (PEs) over the 52-week treatment period.
The aim of the study is to investigate whether long-term heated humidification therapy (AIRVO) administrated for 1 year over-night on top of standard therapy can reduce the number of exacerbations in adults with non-cystic fibrosis bronchiectasis.
Bronchiectasis have multiple etiologies but share a similar bronchial injury associated with inflammation, which leads to a progressive lung deterioration. This disease is responsible for a frequent access to care with an exacerbation rate of 1.8 per year with a high risk of hospitalization. Natural history is marked by recurrent infectious diseases which are the main prognosis factor. This disease is associated with an inflammation rate in the lung as well as in the blood. Up to now, no study has been described comorbidities associated with this chronic disease but our hypothesis is that cardiovascular diseases will be more frequent in these patients. In fact systemic inflammation driven by bronchial infections may increase frequency of cardiovascular diseases. The investigators decide to conduct a monocentric observational study to define the prevalence and characterization of cardiovascular comorbidities as well as markers of accelerated aging. We would like to test the hypothesis that cardiovascular comorbidities are frequent in bronchiectasis and may be associated with markers of inflammation and aging. Phenotype of the lung disease will include: spirometry, plethysmography, DLCO measurement according to the ATS/ERS guideline. 6M walking test and echocardiography will be also performed. Frequency of comorbidities will be calculated with data from questionnaire as well as standardized explorations. Aging related manifestations will be measured: arterial stiffness using aortic pulse wave velocity, bone mineral density using dual energy X-ray absorptiometry. Appendicular skeletal muscle mass and grip test were also performed. Blood test were also performed to measure inflammatory markers, cytokines and length of telomere in circulating leucocytes.
Bronchiectasis is characterized by a permanent and abnormal dilatation of a part of the bronchial tree. An accumulation of mucus in the respiratory tract ensues, resulting in frequent bacterial infections and eventual destruction of the lungs. Clinically, patients present with a chronic productive cough and episodes of acute respiratory exacerbations. Chronic respiratory failure can follow. Although its prevalence is largely unknown, bronchiectasis is considered to be a rare and orphan disease. There are numerous causes for this disease: sequelae of respiratory infections, immunodeficiency, genetic diseases like cystic fibrosis, primary ciliary dyskinesia….The focus of this study will be on non cystic fibrosis bronchiectasis in children. Due to a lack of pediatric clinical trials, the management of children with this disease is widely based on the management of adults or patients with cystic fibrosis or pan-bronchiolitis. The treatment is based on respiratory physiotherapy, prevention of infections, administration of inhaled corticosteroids and anti biotherapy for acute exacerbations. Recently, some studies have demonstrated the efficacy of a family of antibiotics, the macrolides, in the treatment of cystic fibrosis or pan-bronchiolitis in children. Indeed, taken 3 times a week during a long period of time, the macrolides, and specifically the azithromycin have shown some anti-inflammatory and tissue repairing properties, in addition to their antimicrobial properties. Moreover, several studies conducted in the adult population have shown that the use of azithromycin has led to significant reduction in the frequency of respiratory exacerbations as well as an improvement in the quality of life. The efficacy of azithromycin in these respiratory diseases has led to enlarge its use for the long term treatment of bronchiectasis. Yet, this type of treatment has no marketing authorization application. No studies have been conducted in children, but individual examination of patients with bronchiectasis treated with azithromycin suggests an improvement of their symptoms. Thus, the use of azithromycin in the treatment of bronchiectasis in children seems to be a promising therapy. However, its efficacy needs to be demonstrated by clinical trials led on a pediatric population with an adequate number of patients and a strong methodology in order to ensure validity and reliability of the results. Therefore the investigators decided to conduct a comparative, prospective multicenter randomized study in this population. This study intends to include 100 patients already treated by azithromycin for at least 6 months. After inclusion, they will be randomized in two groups of 50 patients each. The first group will continue the treatment and the other one will discontinue it. The patients will be followed from the inclusion period (M0) until the onset of the first exacerbation for a maximum of 6 months (M6), with an intermediate health care visit after 3 months (M3). In case of exacerbation, a health care visit will be scheduled; the patient will receive the appropriate treatment and he will be suspended from the study. The duration of follow up for each patient is dictated by the occurrence of the first respiratory exacerbation, a maximum of 6 months .The total inclusion period is 12 months and the total duration of the study is 18 months.
