Active clinical trials for "Pneumonia"

This study aims at determining clinical presentations and outcomes of patients with covid-19 pneumonia and also follow up of patients for up to 6 months to detect possibility of post covid fibrosis

According to usual practices, HIV testing should be performed for each patient diagnosed for pneumococcal pneumonia. Unfortunately, in 2018, only 27% of patients were tested for HIV following pneumococcal pneumonia in Nice University Hospital. The aim of PneumoVIH protocol is to promote HIV testing by reminding good practices to physicians. To achieve this, the team of the bacteriology laboratory will contact physicians for each patient positive for pneumococcal antigenuria to suggest HIV testing. This prospective public health action will aim to integrate this HIV test into routine care and to evaluate benefits through the number of HIV positive patients that will be diagnosed.

This study investigates the diagnostic performance of an AI algorithm in the detection of COVID-19 pneumonia on chest radiographs.

The investigating group aims at performing an observational, prospective study that involves the evaluation of circulating biomarkers predictive of clinical evolution in patients suffering from COVID-19 disease. In particular, the aim will be to verify whether there are transcripts or cytokines / chemokines in peripheral blood, modulated differently in patients with COVID-19, distinguished on the basis of the evolution towards more severe clinical pictures that require patient intubation or that show signs of cardiovascular damage. The study will be based on the transcriptional analysis of the entire genome and serum protein to evaluate the expression of a broad spectrum of cytokines and chemokines. Genome analysis will allow the genotype to be correlated to the identified gene expression profiles.

The purpose of the study is to determine if the clinical course of pneumonia is more severe when both, bacterial and viral pathogens are find as possible causative agent and how does it affect treatment.

Background: in various pediatric pulmonary diseases such as asthma, cystic fibrosis or bronchopulmonary dysplasia an increased inflammation is present. Measuring this inflammation is often hardly possible and requires invasive techniques such as bronchoscopy. With the use of exhaled breath condensate (EBC) or exhaled breath (EB) analysis it is possible to measure the inflammation in an non-invasive way. However, there is a great need to further standardise these measurements and to identify possible confounding factors.

There is a rare condition causing scarring of the lungs termed interstitial lung disease. This comprises a group of conditions which can be divided into separate diseases. The aim of this study is compare a group of patients (the cases) with 2 types of this disease (fibrotic non-specific interstitial pneumonia (NSIP) and idiopathic pulmonary fibrosis (IPF)) with patients without the disease. The study will look at the 2 groups and their exposures to factors such as medications, smoking, previous jobs, previous medical problems and specifically heart disease and any operations or procedures involving the heart. There have been previous studies showing a link between heart disease and scarring of the lungs. This study will look at whether this association is stronger in one or the other type of lung scarring diseases.

Pneumonia in general and CAP in particular is considered as one of the most common bacterial infections, associated with high rates of morbidity and mortality and is highly significant economically since all respiratory infections, and pneumonia especially, cause about 80% of antimicrobials use in the community. The high frequency of respiratory infections and the excessive use of antimicrobials are major contributors to the development of pathogens resistant to antimicrobials. In addition, in CAP almost all patients are treated empirically, without identification of causing pathogen. Aim of study: To identify common pathogens causing CAP in hospitalized patients in north Israel.

Early-onset pneumonia after out-of-hospital cardiac arrest is frequent. An association between early-onset pneumonia and an increase in morbidity has been reported in this population. The diagnosis of early-onset pneumonia inpatients with out-of-hospital cardiac arrest may be challenging as diagnosis criteria are unspecific in this setting. On the other hand some studies have reported an association between early antibiotics and better prognosis in patients with out-of-hospital cardiac arrest suggesting that early diagnosis and treatment of pneumonia would benefit to patients. Nonetheless, adminitration of antibiotics to any patients with out-of-hospital cardiac arrest would expose to antibiotic patients without infection and woould participate to increase in antibiotic resistance. Therefore, the PP-ACR study aims to evaluate the impact of a diagnosis algorithm including blinded sampling protected brushes on early-onset pneumonia treatment and patient prognosis after out-of-hospital cardiac arrest.

Community-acquired pneumonia (CAP) represents a major health care problem and mortality and morbidity associated with severe pneumonia remain considerable, despite state of the art care. While the role of altered DNA methylation in cancer has been widely studied, knowledge of its impact on antibacterial defense is highly limited. In addition, recent preclinical studies showed that the gut and respiratory microbiota contributes to host defense against bacterial pneumonia. This study aims to explore a completely novel research area linking the extent of DNA methylation in blood leukocyte (monocytes and neutrophils) and function of gut and respiratory microbiota on the influence of innate immune responses to and host defense against CAP
