Active clinical trials for "Pneumonia, Bacterial"

Evaluation of the carriage rate of Streptococcus pneumoniae in the nasopharynx of healthy children and the carriage rate and distribution of Streptococcus pneumoniae serotypes

Retrospective cohort analysis of children hospitalized for pneumonia comparing disease severity on admission, clinical course, treatment and outcomes and prospective telephone based Follow-Up assessement.

This is a prospective study of up to 250 participants, from birth to 18 months, who have already had a chest x-ray while a patient at the National Institute of Health (NICH) in Karachi, Pakistan. Participants will include both males and females as well as all races and ethnicities. Participants will have thermal pictures of their chest taken by trained study staff using a Smartphone and a FLIR ONE attachment. Thermal images will be read by trained radiologists to determine if bacterial pneumonia is present. Results of the thermal image will then be compared to the results of the chest x-ray. If additional images of the chest or other areas of suspected related infection are available, additional thermal images will be taken of the same location within 24 hours of the other image.

A multi-center, retrospective study of cases of serious bacterial infections including complicated Urinary Tract Infection (cUTI) or Acute Pyelonephritis (AP), Hospital Acquired Bacterial Pneumonia (HABP), Ventilator Acquired Bacterial Pneumonia (VABP), and/or bacteremia caused by Carbapenem-Resistant Enterobacteriaceae (CRE)

A prospective observational study. Enrolled participants admitted to ICU due to pneumonia and respiratory failure need mechanical ventilator support. Investigators collected the residual specimens, such as sputum from endotrachea aspiration, bronchoalveolar lavage fluid in those participants as the usual care in the ICU. Those residual samples were sent to extract RNA and sequence by using high-throughput sequencing (next-generation sequencing) method. Investigators will compared the microbiome feature between lower respiratory tract and stool specimens in those participants diagnosed as pneumonia with respiratory failure.

Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.

Prognosis of subarachnoid hemorrhage (SAH) is scarce, indeed almost half patients die or become severely disable after SAH. Outcome is related to the severity of the initial bleeding and delayed cerebral infarction (DCI). Infection and more precisely pneumonia have been associated with poor outcome in SAH. However, the interaction between the two pathologic events remains unclear. Therefore, we hypothesized that DCI may be associated to pneumonia in SAH patients. Thus the aim of the study is to analyze the association between delayed cerebral infarction and pneumonia in patients with SAH. Retrospective, observational, monocentric cohort study, including patient admitted in Neurosurgical Intensive Care Unit or Surgical Intensive Care Unit in the University Hospital of Brest (France) for non-traumatic SAH. Primary outcome is diagnosis of DCI on CT scan or MRI 3 months after SAH. Multivariate analysis is used to identify factors independently associated with DCI. We plan to include between 200 and 250 patients in the analysis.

The purpose of this study is to better define the intensive care unit population at highest risk for developing Hospital-Acquired and Ventilator-Associated Bacterial Pneumonia (HABP/VABP).

This is a study of up to 275 participants from birth to 12 months who are having a chest x-ray while a patient at the Queen Elizabeth Central Hospital in Blantyre, Malawi. Participants will have thermal pictures of their chest taken by trained study staff using a Smartphone and a FLIR ONE attachment. Thermal images will be read by trained study staff to determine if bacterial pneumonia is present. Results of the thermal images will then be compared to the results of the chest X-ray. If additional images of the chest are available, additional thermal images will be taken of the same location within 24 hours of the other image.

The pandemic triggered by the new SARS-CoV-2 presents the German health system with previously unknown challenges. There are currently no effective therapies for the treatment of the SARS-CoV-2 lung disease Covid-19. The aim of the joint project PROVID is to draw conclusions from the often very different clinical appearance of infections with the SARS-CoV-2 pathogen in order to improve patient care through targeted clinical management. The effects of infections with the SARS-CoV-2 pathogen are wide-ranging and include a spectrum from symptomlessness to infections of the upper respiratory tract, uncomplicated but also severe pneumonia with lung failure and high mortality. PROVID will first check whether certain host factors determine the severity and / or the course of Covid-19. Research is also being carried out into whether the molecular and clinical values of Covid-19 patients differ from those of patients with pneumonia caused by other pathogens. In addition, it will be tested whether specific molecular markers describe the severity of the disease and are suitable as an aid for targeted therapy for Covid-19. PROVID is an interdisciplinary joint project made up of three sub-projects that are being implemented at three locations (Charitè-Universitätsmedizin Berlin, Universität Leipzig IMISE and CAPNETZ STIFTUNG / Hannover). PROVID is based on three clinical research platforms with a high track record in recruiting patients with high-quality data and biomaterials on the one hand and guideline-changing results on the other hand: CAPNETZ (competence network CAP, since 2002, world's largest database and biobank for CAP), PROGRESS (Pneumonia Research Network on Genetic Resistance and Susceptibility for the Evolution of Severe Sepsis, since 2007) and CAPSyS (systems medicine of community-acquired pneumonia, since 2014). The COVID-19 patients are recruited into 3 different patient cohorts via these 3 research platforms. 1. PROVID-CAPNETZ, 2. PROVID-PROGRESS, 3. PROVID-CAPSyS.
