Bronchiectasis and Long Term Azithromycin Treatment
Rationale: Patients with bronchiectasis often experience lower respiratory tract infections with progression of symptoms and decline in quality of life. Macrolides, as has been shown in panbronchiolitis and cystic fibrosis, may break or weaken the link between infection and inflammation resulting in an improvement of symptoms. Also the number of exacerbations may lowered.
Objective: A reduction in number of infective exacerbations and improvement in lung function by AZT treatment are the primary objectives. Secondary objectives that will be evaluated are: symptoms score, quality of life, inflammatory parameters, bacterial colonisation, and adverse events.
Study design: Randomised double blind multicenter study in the Netherlands. Patients will be stratified for colonisation with P.aeruginosa.
Study population: Patients with bronchiectasis demonstrated by high-resolution computed tomography (HR-CT) scan or bronchography.
Intervention: Patients receive Azithromycin 250mg(p.o.) once daily or placebo.
Main study parameters/endpoints: Reduction in number exacerbations, defined as increase symptoms such as dyspnoea, coughing, and sputum production for which a course of prednisolone and/or antibiotic is needed. Change in lung function parameters (forced expiratory volume in 1 second [FEV1], forced vital capacity [FVC]) measured by spirometry is the other primary endpoint.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The risk of participating in this study is low. Laboratory, radiographic examinations, and pulmonary function tests are commonly used as diagnostic procedures during outpatients visits and during exacerbations. Adverse effects in maintenance treatment with AZT are usually mild and mainly gastrointestinal. Sometimes rash and abnormal liver function tests are observed. A better quality of life will probably be the beneficial effect of long term treatment with AZT. This will be achieved by a reduction in respiratory and non-respiratory symptoms and number of exacerbations.

Persistent abnormal dilatation of the bronchi.
A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
The purpose of this study is to investigate if treatment with AZD9668 for 28 days is effective in treating Bronchiectasis (Brx) and if so how it compares to placebo (a substance which does...
This is a study to determine the safety and tolerability of 28 days of daily dosing of two doses (280mg and 560mg) of Arikace™ versus placebo in patients who have Bronchiectasis.
Considering that respiratory physiotherapy lack scientific evidence to support its application in the treatment of several obstructive diseases, this investigation was designed to evaluate...
Over the 70-day study period, eligible patients will visit the study clinic every 2 weeks (total of 6 visits) and will receive a 28-day course of aztreonam for inhalation solution. Quality...
The purpose of this study is to determine whether the daily inhalation of nebulised hypertonic saline (6%) will decrease the incidence of pulmonary exacerbations and increase the quality o...
Azithromycin (AZM) has unique pharmacokinetic and pharmacodynamic characteristics that give it unusual clinical properties for an antibiotic. Gradually, potential indications have increased reaching a...
Long-term macrolides are increasingly being prescribed for stable bronchiectasis. This meta-analysis assessed the clinical effect of this treatment in bronchiectasis. A systematic review and meta-anal...
Azithromycin is a macrolide antibiotic with anti-inflammatory and immunomodulating effects. Long-term azithromycin therapy in patients with chronic lung diseases such as cystic fibrosis has been assoc...
The aim of this study was to determine the effect of azithromycin on LPS-induced pregnancy loss. Thirty-six pregnant female Wistar rats were divided into 4 equal groups as follows: control group, wher...
The purpose of this descriptive review was to delineate the current knowledge of bronchiectasis in terms of prevalence, burden of disease, pathophysiology, and management.
