Active clinical trials for "Bronchitis, Chronic"

A study to report the outcomes of patients who fail to respond to beta-lactam and macrolide antibiotics in the community

Chronic Obstructive Pulmonary Disease (COPD) is a common progressive lung disease which causes breathlessness and frequent exacerbations, with patients often requiring hospitalisation. Patients with severe COPD commonly become housebound and lose their independence. They have a higher symptom burden than those with incurable lung cancer, yet are less likely to receive specialist palliative care, or to have been engaged in advance care planning (where patients discuss and often document their wishes regarding their future care). Hospital admissions become increasingly common towards the end-of-life; therefore, hospitalisation is a good opportunity to identify patients at risk of poor outcome. Such patients may wish to consider alternatives to admission and avoid intrusive treatments. Unfortunately, predicting which patients are likely to die in the near future is challenging thus far. The first step required to improve provision of palliative care services, and ensure patients are given the opportunity to make truly informed decisions about their future care, is accurate identification of those most likely to benefit. Well-designed clinical (prognostic) tools outperform clinician judgement in most settings. The investigators will compare the accuracy of one year mortality prediction of several clinical tools in patients who survive a COPD exacerbation requiring admission. This will initially be performed using existing data collected during previous research (the 1,593 patient validation study for the PEARL score - Previous admissions, extended Medical Research Council Dyspnoea score, Age, Right and Left heart failure), then confirmed in at least 310 patients admitted uniquely and consecutively with an exacerbation of COPD. The latter group of patients will be invited to participate in a longitudinal follow-up study, assessing symptom burden, quality of life, and readmissions over one year.

Evaluation of immunogenicity and safety of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease recruited to receive the schedule of two doses inactivated COVID-19 vaccine with the interval of 21 days .

The objective of this global non-interventional study is to evaluate the impact of Acute Exacerbation of Chronic Bronchitis(AECB) on the patient and the community as well as the safety and effect of a treatment with Moxifloxacin tablets in daily life clinical practice. This includes data on the course of symptom relief, speed of return to normal daily life activities as well as records on adverse events. This study will be performed in accordance with international guidelines like EMEA (EMEA, EUDRALEX Volume 9A, Pharmacovigilance for Medicinal Products for Human Use) as well as local laws.

This study is a local, prospective, open-label, company-sponsored, non interventional, multi-center study. Patients documented must suffer from an acute exacerbation of chronic bronchitis and take at least one dose of Moxifloxacin injection.The primary objective is to obtain clinical effectiveness and safety data of Moxifloxacin injection in the treatment of acute exacerbations of chronic bronchitis in patients in whom Moxifloxacin was routinely prescribed. The secondary objective is to find out the possible correlation between the risk factors (sex, smoking, number of previous exacerbations, etc) and AECB, the different treatment effectiveness according to Anthonisen classification. This study will also collect the data of pathogens by sputum culture and the defervescence time of Moxifloxacin injection in treating Acute Exacerbations of Chronic Bronchitis (AECB).

The aim of this study is to examine the inflammatory mechanisms involved in the pathogenesis of inflammatory lung disease, in particular to compare the inflammatory profile seen in asthma and COPD. Evidence for inflammation in asthma and COPD is based on the finding of increased numbers of macrophages and neutrophils in the lungs and respiratory secretions of these patients. The inflammatory cells produce proteases, as well as, reactive oxidant species resulting in a protease/anti-protease imbalance which favours lung destruction. The aim is to examine the inflammatory mediators released by inflammatory cells (such as, macrophages and lymphocytes) in order to determine whether there are differences between non-smoking subjects, smoking subjects and patients with asthma or COPD. Monocytes are precursors of alveolar macrophages, and both monocytes and neutrophils are recruited to the lung from the blood via the action of specific chemoattractants. We have evidence that in inflammation there are higher levels of these chemoattractants. Therefore these cells might also demonstrate the same changes seen in alveolar macrophages from these patients. We also aim to assess the role of the macrophage precursor (monocyte) and neutrophils in the blood. We will also assess lymphocyte/monocyte interaction. We will do this as the lymphocyte may be involved in the initial recruitment of inflammatory cells. We will also assess the role of cytokines involved with monocyte/macrophage/neutrophil migration in induced sputum as well as the role of induced sputum in the migration of monocytes and neutrophils into the lung. Our aim is to link the initial changes in blood to the changes causing disease in the lungs. We aim to examine cellular responses in four groups of subjects, namely (i) non-smoking controls, (ii) smokers without clinical evidence of COPD or asthma, (iii) smokers with COPD (iv) asthmatic patients.

Patients with chronic lung diseases such as Chronic Obstructive Pulmonary Disease (COPD), who perform regular physical activity, have improved health and wellbeing compared with those who do little exercise. The purpose of the study is to evaluate whether the use of a simple pedometer (step counter) to set targets for daily physical activity can encourage COPD patients referred for an 8-week pulmonary exercise based programme (PR) to be more active. The investigators also want to know whether the use of pedometers during PR can improve adherence, self-management and outcome in COPD.

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.

Evaluation of immunogenicity and safety of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease recruited to receive the schedule of three doses of inactivated COVID-19 vaccine on day 0, day 21 and day 111, respectively .

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.
