Active clinical trials for "Pneumonia"

There has never been a paper published or research done to determine the rate of Legionella species as a cause of community or nosocomial acquired pneumonia requiring hospitalization in Malaysia. Anecdotally, Legionnaires' disease is thought to be uncommon in Malaysia. This is one of the first prospective hospital-based studies to comprehensively evaluate the epidemiological and demographical factors of patients hospitalized with Legionella infection in Malaysia.

Severe community acquired pneumonia is common and associated with high mortality. Conventional microbiological diagnostics identify pathogens in approximately half of cases, which is inadequate for both clinical and epidemiological purposes. This study applies next-generation sequencing based metagenomic techniques to patients with extremely severe community acquired pneumonia, to investigate the microbiome of severe community acquired pneumonia and evaluate metagenomic approaches as diagnostic tools.

Collagens are proteins present in all tissues. Besides their structural role, recent data showed that they were able to regulate many cellular functions. Many interactions occur between extracellular matrix macromolecules, especially collagen, and various cell types. These interactions can be controlled by peptides derived extracellular matrix macromolecules, called matrikines. Previous work from the investigators laboratory and others have shown that several C-terminal domain (NC1 domains) from basement membrane-associated collagens could regulate many cellular activities. Lung is an organ particularly abundant in basement membranes. It is likely that various lung diseases may affect metabolism of basement membrane associated collagens. To the investigators knowledge, no study has focused on the expression of collagen XIX α1 chain and collagen IV chains α3 and α4 chains in lung and studied possible variations of expression in various pathophysiological situations. The aim of this study are to: Study the presence of collagen IV and XIX (or fragments) in different types of sampling such as bronchoalveolar lavage, pulmonary aspiration and bronchial biopsies Evaluate quantitative variations of expression of these collagen in different pulmonary diseases, especially chronic obstructive bronchopneumopathy, infectious pneumonia, pneumonitis or lung cancer.

The purpose of the study was to describe early predictors and to develop a prediction tool that accurately identifies the need for mechanical ventilation in pneumonia patients with acute respiratory failure treated with High Flow nasal cannula.

Pneumonia is a common infectious disease of the lung, often requiring treatment in the hospital. Clinical scoring systems are available, identifying patients not requiring hospitalization. However, the course of disease of patients in the hospital remains hard to predict. While most patients will recover quickly, some will, despite appropriate treatment, develop a severe course leading to sepsis and systemic responses resulting in organ dysfunction. The PROGRESS study aims to identify clinical, genetic, and other molecular markers and combinations thereof predicting a severe course of pneumonia in the hospital. Such predictors will, for instance, support decisions on earlier transfer of patients to intensive care and thus improving outcome.

Statement of the problem: Overprescription of antibiotics raises important public health issues because of the emergence of multiresistant bacteria by selection pressure. The results of the observational prospective study entitled "CAPA" on the description of 886 suspected cases of acute community-acquired pneumonia (CAP) treated in general practices in France confirm that, whatever the etiologic hypothesis and the results of the chest X-ray, these patients routinely receive antibiotics. Therefore, it is important to be able to distinguish cases of pneumococcal CAP in which early antibiotic treatment is justified from those cases for which another strategy could be considered. Primary objective: To identify the clinical, biological and radiological characteristics of patients with pneumococcal CAP amongst all patients with CAP radiologically confirmed, in general practice in France. Design : Prospective cross-sectional descriptive study. Inclusion criteria. Adults older than 18 showing clinical signs suggestive of CAP (at least one sign of infection and at least one pulmonary sign) and able to realize chest X ray within 6 hours after prescription. Patient follow-up procedures. Patients will be treated by standard of care according to French recommendations. After observing clinical signs suggestive of CAP, the physician prescribes a chest X-ray. Then, protocol-specific examinations (blood sample, oropharyngeal sample for multiplex polymerase chain reaction (PCR), sputum sample testing (induced expectoration if possible), urinary sample) will be performed on all out patients. Patients will be contacted again on day 28 to increase diagnostic certainty. For patients with clinical signs of CAP and hospitalized, the investigator will ask their consent to retrieve the hospital report, on or before day 28 and to be contacted on day 90.

Observation of prescription usage of anaerobic antibiotics for patients admitted to the ICU with pneumonia.

The concern with oral infection and its systemic repercussions is old, many studies have been undertaken to establish this relationship more precisely. One of the areas mouth still little studied in this regard is the colonization of language within this universe of the oral microbiota colonization and how this may affect the general state of health care-dependent individuals. This research aims to evaluate the efficiency of a tongue cleaning device and its potential impacts on infectious patients fully or partially dependent care hospital. Patients admitted to intensive care units and inpatient units will be evaluated, divided into two groups: Study Group (SG) - Patients who receive oral hygiene using the tongue cleaning device, and Control Group (CG) - Patients who are cared for according to the routine of hospital nursing.

With this study the investigators want to determine, if a fast identification of germs, causing infections of the lower respiratory tract, is possible through the use of Multiplex PCR technology - a method that allows on time detection of bacteria in medical specimen by identifying DNA sequences that are known to be specific for the respective microbe. Therefore aspiration samples from the respiratory tracts of ventilated patients, which are suspected to develop such an infection, will be collected and analyzed by using a multiplex PCR (polymerase chain reaction) application situated on the intensive care unit. The investigators want to determine if Multiplex PCR diagnostic could be a faster alternative to conventional microbiological methods. The results of the Multiplex PCR analyses therefore will be compared with results of conventional microbiological methods.

Inhalation is a common condition in patients with impaired their awareness requiring protection of the upper airway by endotracheal intubation. This inhalation may lead to chemical pneumonitis and/or bacterial pneumonia. Only the latter requires the administration of antibiotics. Patients developing such a bacterial pneumonia, has a mortality, duration of mechanical ventilation and length of ICU stay increased. However, the proportion of patients with such bacterial pneumonia, bacterial ecology and morbidity that are little known. The aim of this study is to determine the frequency of bacterial pneumonia in patients admitted to the ICU for coma and treated with mechanical ventilation
