Filter by:Streptococcus pneumoniae is a gram-positive (GP) bacteria responsible for common infections such as community-acquired pneumonia (CAP), as well as complicated infections such as bacteremia, infective endocarditis and meningitis. S. pneumoniae bacteremia ranks among the top 10 most common pathogens associated with bloodstream infections and correlates with high morbidity and mortality worldwide.
This study is a phase III clinical trial to evaluate the immunogenicity and safety of the 13-valent pneumococcal conjugate vaccine (multivalent conjugate) in infants aged 2 months (at least 6 weeks) and 3 months. The main objectives of the study include: 1. To evaluate the immunogenicity of the trial vaccine in infants aged 2 months (at least 6 weeks) following the corresponding immunization schedule compared to the control vaccine; 2. To evaluate the immunogenicity of the trial vaccine in infants aged 3 months following the corresponding immunization schedule compared to the 2-month group; 3. To evaluate the safety of the trial vaccine in infants aged 2 months (at least 6 weeks) and 3 months following the corresponding immunization schedule.
The 'Experimental Human Pneumococcal challenge' (EHPC) model is a way of putting drops of bacteria into the nose. Investigators have studied this model of putting bacteria in the nose safely in over 1500 volunteers over the past decade with no serious side effects and now want to test the model using a different strain of the bacteria that is commonly found in the community, SPN3. The aim of this study is to determine how much pneumococcus is needed to achieve nasal colonisation and how long the bacteria live in the nose for before natural immune responses eradicate them. By doing this, Investigators will then be able to test how well future vaccines prevent colonisation with pneumococcus. Investigators want to learn more about how the immune system responds to nasal colonisation with pneumococcus, again to help with development of new vaccines.
The purpose of this research is to conduct a multi-center prospective surveillance study focusing upon pneumococcal carriage and serotype epidemiology in patients with otitis media (OM).The data generated will be crucial especially as baseline data for future assessments on the long-term impacts of pneumococcal conjugate vaccine 10 (PCV10) coverage, compared to that of pneumococcal conjugate vaccine 13 (PCV13) that is being used in the majority of other countries. Pneumococcal carriage in patients with OM and serotype distribution will be assessed, including changes in antibiotic resistance. With the establishment of sentinel surveillance in the country, we hope to provide detailed data on the epidemiology of OM in Malaysia; working towards the development of a national surveillance programme for the monitoring of OM burden in the country.
This phase II trial tests whether the pneumococcal pneumonia vaccine series (PCV20 and PPSV23) works to mount an effective immune response in patients with chronic lymphocytic leukemia. PCV20 and PPSV23 are both vaccines that protect against bacteria that cause pneumococcal disease. Giving these vaccinations as series may make a stronger immune response and prevent against pneumococcal infections in patients with chronic lymphocytic leukemia.
In France, Streptococcus pneumoniae is the leading agent bacterial involved in community lung disease and meningitis. The frequency of these infections and their mortality increase significantly in those at risk such as patients with certain chronic diseases, immunocompromised or on immunosuppressive therapy. This population, despite regular monitoring, has a limited pneumococcal vaccine coverage of around 20%. By carrying out a reconciliation of treatments upon admission to hospital, the clinical pharmacist can detect those without up to date pneumococcal vaccination status. The goal of this management is to make the patient aware of the need for vaccination and organization upon return home. Thus, this limited pneumococcal vaccination coverage would benefit from intervention by regional clinical pharmacy activities. The study investigators want to study the impact of a structured medico-pharmaceutical collaboration on pneumococcal vaccination of patients with risk on discharge from hospital. The investigators hypothesize that this collaboration in patients at risk of infection with pneumococcus could significantly increase their anti-pneumococcal vaccination coverage
To determine the effect of PCV-13 and PPV-23 vaccination versus control on experimental pneumococcal colonisation of 2 clades of serotypes 3 and 6B at 1 month and 6 months post vaccination respectively, using the EHPC model.
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.
Streptococcus pneumoniae (pneumococcus) is a commensal bacterium, often isolated in the nasopharynx of preschool children and older adults with weakened immune systems, a pathogen that remains the leading cause of Community-Acquired Pneumonia (CAP) and invasive pneumococcal disease (IPD) such as Sepsis and Meningitis. CAP is the sixth leading cause of overall mortality and the first cause of infectious disease in Colombia and the world (Montúfar et al, 2013; GBD, 2016; WHO, 2018), and both its incidence and prevalence have remained stable over the past 3 decades. Likewise, CAP due to S. pnemoniae is the most common cause of lower respiratory tract infections in humans worldwide and is associated with high morbidity and mortality in patients who suffer from it. Pneumococcus frequently colonizes the nasopharynx of children and adults and, therefore, this condition has been postulated as a risk factor for the development of CAP. There are reports of the effect of nasopharyngeal colonization in infants, but the implications of this colonization in adults, especially adults with chronic comorbidities, are not known. Additionally, several studies point to a relationship between pathogenicity, colonization capacity, and disease severity according to the infecting pneumococcal serotype. Therefore, it is not known which pneumococcal serotypes are most frequently colonized by adults with chronic diseases (cardiovascular disease (CVD), chronic obstructive pulmonary disease (COPD), renal disease (RHD), rheumatological disease (MDR), Diabetes Mellitus (DM), among others) and the potential clinical implications of this colonization. For these reasons, this research aims to study the phenomenon of colonization by pneumococcus in patients with chronic diseases for the development of CAP, and the relationship between the virulence genes of different serotypes and the outcome in invasive pneumococcal disease (IPD). This study is based on real evidence (from clinical practice) and translational medicine, is prospective-observational, multicenter and cohort type in consecutive patients. Thus, in a first phase the clinical observation of the subjects will be carried out, a second phase of follow-up and sampling in the patients, and a third phase of molecular analysis.
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.
