Filter by:Given the need for a more sensitive pathogen detection test in patients with immunocompromised pneumonia, this study will evaluate the performance of the Karius Test, a novel NGS blood test for the diagnosis of infectious diseases. We will compare the performance of the Karius Test to the results of microbiologic tests obtained as part of usual care for immunocompromised patients undergoing evaluation for suspected pneumonia.
Pneumonia is a major infectious cause of death worldwide and imposes a considerable burden on healthcare resources. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid and involved in many physiological processes including immune responses and endothelial barrier integrity. In term of endothelial barrier integrity, S1P plays a crucial role in protecting lungs from pulmonary leak and lung injury. Because of the involvement in lung injury, S1P could be the potential biomarker of pneumonia. Recently, our pilot study suggested that patients with CAP have significantly higher plasma S1P levels than healthy individuals. Interestingly, our observational study also showed significantly elevated S1P level in the patients who were treated with methylprednisolone during the hospitalization. Based on the above evidence, we hypothesize that S1P plays an important role in the pathobiology of pneumonia. Moreover, S1P is not only a useful biomarker for diagnosis of CAP, but also can be an indicator for using corticosteroids adjuvant therapy.
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.
This study evaluates the relation between the volume of subglottic secretion before airway extubation and the risk of extubation failure in the ICU patient.
This is a 2-part study, with Part A being the randomized, controlled portion of the study in patients with ABC hospital-acquired bacterial pneumonia (HABP), ventilator-associated bacterial pneumonia (VABP), or bacteremia. Part B is the single-group portion of the study and includes ABC infections that are resistant to or have failed colistin or polymyxin B treatment, as detailed in the inclusion criteria.
Previous studies have shown that a small incentive can have a large impact on health behaviors like vaccinating children. New Incentives, an international non-governmental organization (NGO), aims to boost demand for immunization by offering cash incentives to caregivers who have their child vaccinated at a program clinic. In collaboration with New Incentives, IDinsight is conducting a study to see whether this approach will increase immunization in North West Nigeria. This study aims to investigate whether giving cash to caregivers in North West Nigeria who bring their infants to receive vaccination against common infections (tuberculosis, diphtheria, tetanus, pertussis, hepatitis B virus (HBV) infection, Haemophilus influenzae Type B (Hib), pneumococcal bacteria, measles, rotavirus, polio, yellow fever) increases the proportion of children who are immunized. The study's main hypothesis is that New Incentives' program will increase the percentage of children immunized with BCG, any PENTA, or Measles 1 by an average increase of at least 7-percentage points across all program clinics that share a similar profile to the clinics New Incentives will operate in at scale. The study is taking place in Jigawa, Katsina, and Zamfara States between August 2017 and January 2020.
The primary purpose of the study is to determine the degree of penetration of cefiderocol into infected lung tissue in hospitalized adults with bacterial pneumonia who are being mechanically ventilated.
This study will look for new biomarkers of infection and evaluate current biomarkers of infection in stroke patients. Patients with acute stroke will be monitored with daily blood samples for seven days and by clinical examination to detect infections for 10 days.
The purpose of the study is to evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator Prevnar 13® (PCV13) in adults 18 to 64 years of age in Stage 1. Stage 2 will evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator PCV13 in elderly 65 to 85 years of age. In addition, Stage 2 will evaluate the immunogenicity of 3 different dose levels of ASP3772 relative to the response seen following administration of Pneumovax® 23 (PPSV23) for the serotypes not included in PCV13.
Background: In thoracic surgery, postoperative pneumonia (POP) is the leading cause of postoperative morbidity and mortality. The clinical diagnosis of POP is difficult and conventional microbiological diagnostic tests perform poorly. The contribution of molecular diagnostic tests (multiplex PCR, mPCR) should be evaluated to optimize the diagnostic and therapeutic management of POP. Objectives: The main objective is to describe the microbiological relationship between the existence of pre- (if available) and intra-operative bronchial and pulmonary bacterial colonization and the occurrence of POP. The secondary objectives are to analyze the contribution of the mPCR for the diagnosis of POP and to validate the predictive factors of POP described in the literature Material and methods: A monocentric prospective non-interventional research with minimal risks and constraints. The study population is represented by all the consecutive adult patients hospitalized for lung surgical resection (except surgical resection indicated for infectious disease) during one year. The preoperative respiratory samples within the 3 preceding months (date and type, pathogen and threshold) are recorded, if available. Intra-operative bronchial aspirate is performed for direct examination and culture (pathogen and threshold) and mPCR (PCR1). A mPCR is optionally performed on the surgical specimen (PCR2). In case of postoperative clinical suspicion of POP, invasive or non invasive samples of respiratory tract secretions are obtained for direct examination and culture (pathogen, threshold) and mPCR (PCR3). A clinical pulmonary infection score (CPIS) is calculated by integrating the results of conventional tests (CPIS1) and mPCR (CPIS2). The pre / intra operative and postoperative microbiological relationship will be described qualitatively and quantitatively and analyzed using correlation tests. Concordances and discrepancies between conventional tests and mPCR will be studied to analyze the contribution of molecular tests in this context.
