Filter by:The aim of this post-marketing observational study (PMOS) is to describe the relief of symptoms, tolerability and compliance of treatment with Klacid®SR in a dose 1000 mg once daily in patients with lower respiratory tract infection or in patients with acute exacerbation of chronic bronchitis (AECB) or mild community-acquired pneumonia (CAP).
To describe the relief of symptoms, tolerability, and compliance of treatment with Klacid® sustained release (SR) at a dose of 1000 mg once daily in patients with acute tracheitis, acute tracheobronchitis, acute bronchitis, or in patients with acute exacerbation of chronic bronchitis or mild community-acquired pneumonia. This postmarketing observational study is non-interventional and is being conducted in a prospective, single-arm, single-country, multicenter format. Klacid SR will be prescribed in usual manner in accordance with the terms of the local market authorization with regards to dose, population, and indication as well as with local guidelines.
The main purpose of this project is to establish the additional value of eccentric versus concentric exercise to optimize muscle function in patients with severe COPD. With this pilot project the investigators expect that an eccentric endurance training protocol adapted to severe COPD patients will lead to gains in muscle strength, the primary outcome, and cellular adaptation (muscle morphology and oxidative capacity, mitochondrial respiratory capacity) when compared to a concentric training approach. This information will be essential if the investigators want to design and power a randomized clinical trial that will allow assessing effectiveness of this novel rehabilitation approach.
The purpose of this study is to demonstrate the efficacy of azithromycin to produce a significant change in the cough-related health status, measured with the Dutch version of the Leicester Cough Questionnaire in patiënts with COPD gold classification 2-4 and chronic productive coughing.
This single-center, randomized, double-blind and controlled study aims to examine the effect of a fermented dairy product containing the probiotic Lactobacillus casei DN-114 001 (Actimel® = tested product) on the incidence of respiratory and gastro-intestinal common infectious diseases (cumulated number of infections during the intervention period: primary criteria), and on immune functions in healthy shift workers. Volunteers received either 200g/day of tested product (N=500) or control product (N=500) for 3-months, followed by a 1-month follow-up.
We aim to study whether the use of inhaled antibiotics may have an impact on the incidence of tracheobronchitis and pneumonia associated with the use of mechanical ventilation. The investigators hypothesize that this could be possible by decreasing the population of gram negative germs that colonize the lumen of tracheal tube and upper airways.
Cigarette smoking is the major risk factor for chronic obstructive pulmonary disease (COPD, commonly known as chronic bronchitis and emphysema). Despite this clear link, only 15-20% of smokers develop COPD suggesting that genetic factors affect the lung's susceptibility to the stress of cigarette smoke. The cells lining the airways (epithelium) and cells that help defend the lung (alveolar macrophages) of smokers develop gene expression changes that are different from that of nonsmokers. In the investigators' previous studies they have demonstrated that there are greater than 200 genes that are responsive to cigarette smoke in these cells. But the investigators do not know whether the gene expression is static or changes as a function of time. Genes that show significant changes over time may be relevant to the progression of the disease. Even though quitting smoking reduces the rate at which the lungs decline, many-smokers still go on to develop COPD. This study will provide insights into the natural history of smoking-related gene expression of the lung cells in health and disease.
The observation period for each patient covered an initial treatment period with Avelox® plus optional 2 long-term follow-up periods (6 and 12 months).For each patient, the physician documented data at any initial visit (baseline) and at least one short-term follow-up visit (=initial treatment period).Optionally, long-term follow-ups (6 and 12 months) were documented, and a patient questionnaire was filled in.
The purpose of this research is to understand the properties of mucus in persons with COPD, specifically Chronic Bronchitis. We hypothesize that those with Chronic Bronchitis have dehydrated mucus, and thus have a harder time coughing it out of their lungs. This leads to a greater vulnerability for lung infection, inflammation and airflow obstruction. Ultimately, our goal is to understand how mucus dehydration contributes to the progression of COPD/Chronic Bronchitis so that better therapies and interventions can be developed for future generations.
In this study data of patients with moderate or severe acute exacerbations of chronic bronchitis (AECB) were collected. There were two different cohorts which were compared (Moxifloxacin and other antibiotics) concerning effectiveness and tolerance. It was a prospective study which was accomplished in 100 ambulatory practice offices.
