Filter by:This multicenter retrospective observation study is designed to investigate the etiology of children with bronchiectasis by review the medical records.
The purpose of this study is to compare physical activity levels between patients with bronchiectasis and healthy subjects. We hypothesize that patients with bronchiectasis will have lower levels of physical activity, since physical activity levels is affected by reduced exercise tolerance, severity of disease and other disease related symptoms and conditions.
The purpose of this study is to determine which treatment is more effective and safer for the patients in COPD C group with bronchiectasis.The research results will help guide physicians to select appropriate individualized treatment and hopefully provide some evidence-based medicine proofs for revising guide.
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.
This is a multicenter, prospective observational cohort study, in which patients with chronic airway diseases including chronic obstructive pulmonary disease(COPD), asthma, asthma-COPD overlap syndrome (ACOS) will be recruited.
Background: Association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied and the aspiration of periodontal pathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. Bronchiectasis is clinically quite similar with COPD, including chronic administration of antibiotics, increased systemic inflammation and relatively similar clinical symptoms, but for the time being; there are no studies that have correlated this condition to PD. This study will evaluate if the scaling and root planning (SRP) associated with photodynamic therapy improves periodontal clinical parameters, halitosis, and the quantity of microorganisms associated with exacerbation of bronchiectasis in saliva, subgingival periodontal microenvironment, sputum and nasal lavage at baseline, after 3 months and one year of SRP. Methods/Design: Ninety patients with chronic periodontal disease and bronchiectasis will be enrolled in the study and they will be treated as follow:G1 control (n = 30) - supragingival scaling (SS) and dental hygiene orientation (DHO); G2 experimental (n = 30) - SRP + DHO; G3- experimental (n = 30) - SRP + PDT + DHO. The quantification of bacterial groups commonly associated with exacerbation of bronchiectasis (P aeruginosa, S. aureus) and periodontal diseases (P. gingivalis), will be evaluated in periodontal pockets, saliva, nasal lavage and sputum by quantitative PCR at baseline 3 months and one year after the SRP. G1 patients will receive SRP upon completion of the investigation. If the mean depth of probing of this group worsen (> 1mm) at 3 months they will be excluded from the study, treated (SRP) and the data will be described. Discussion: The results of this protocol will determine the efficacy of periodontal treatment in decreasing the total amount microorganisms in saliva periodontal pocket, sputum and nasal lavage, the most probable niches of bronchiectasis exacerbation, and reducing local inflammation and halitosis after 3 months and one year. It is expected an higher improvement in all parameters measured over 3 months and 1 year for G3
Bronchiectasis is characterized pathologically by the abnormal and permanent dilation of bronchi caused mainly by the perpetuation of inflammation and impaired clearance of secretions. Physical therapy is essential in the treatment of these patients, using its various techniques and devices. The aim of this study is to evaluate the impedance of the respiratory system, by impulse oscillometry, after breathing exercises with chest compression or flutter in patients with bronchiectasis, considering that there are no results in the literature on the effect of these techniques in the small airways of these patients.
The therapy of bronchoalveolar lavage and local amikacin injection as one of the treatment of bronchiectasis developed in recent years.this study is aim to evaluate the Clinical Efficacy and Safety of Therapy of Bronchoalveolar Lavage and Local Amikacin Injection in Patients with Acute Exacerbation of Bronchiectasis.
This study evaluates vitamin D as an adjunctive treatment in patients with non-Cystic Fibrosis bronchiectasis, which are combined with vitamin D deficiency. Half of participants will receive vitamin D supplementation, while the other half will receive placebo.
It is acknowledged that IL-18, as a product of the inflammasome, is involved in host defence against viral and bacterial stimuli by modulating the immune response. The aim of this study was to determine IL-18 levels in serum of patients with Bronchiectasis and to investigate whether macrolide attenuate its levels.
