Filter by: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.
The research will be retrospective, and will include all patients who were admitted during 2020 and 2021 in the COVID-19 ICU of University Hospital Center Osijek due to pneumonia caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The association of chest x-ray infiltrate evolution with changes in laboratory inflammatory parameters and respiratory function parameters will be examined.
Patients with severe Coronavirus Disease 2019 (Covid-19) pneumonia depending on mechanical ventilation are at risk of superinfections, especially infections of respiratory tract. This multicententer prospective observational study is focused on early diagnosis of respiratory tract superinfections and identification of risk factors (immunosuppressive therapy,...). Investigators will use bronchoalveolar lavage fluid (BALF) for Polymerase Chain Reaction (PCR) detection of pathogens and antigenic detection of mycoses. This project can support the routine use of BALF and PCR diagnostics for early detection of pathogens. Data will be compared with historical cohort of patients without routine BAL.
For patients with suspected pneumonia presenting to the emergency room, the imaging strategy most often involves a frontal and lateral chest x-ray despite poor diagnostic input. Indeed, the radiography is not very sensitive and specific for the diagnosis of pneumopathy compared to the scanner. However, the scanner remains the gold standard, the major constraint of which concerns the irradiation to which the patient is exposed. The new scanners allow ultra-low-dose scans with better sensitivity than standard radiography with an equivalent dose of radiation. In addition, the ultra-low-dose scanner helps prevent diagnostic errors and unintended treatments. A low-dose CT scan for suspected pneumonia has been possible in the Strasbourg emergency department since March 2019. The investigators therefore hypothesize that a diagnostic strategy involving the performance of a low dose CT scan in the event of suspicion of pneumopathy in the emergency room makes it possible to improve the adequacy of the diagnosis made by the initial imaging examination and the diagnosis on discharge from hospitalization, to reduce respiratory or hemodynamic complications and to reduce the prescription of antibiotic therapy that is not suitable for the patient. course of the imaging result validated by a panel of emergency physicians and infectious disease specialists based on medical records in accordance with the recommendations.
Increasing emergence of multidrug resistant (MDR) bacteria worldwide is now considered one of the most urgent threats to global health. The association between increase of antibiotics consumption and resistance emergence has been well documented for all patients admitted to the Intensive care unit (ICU) who received antibiotic treatment and for patients treated for ventilator associated pneumonia (VAP). Reduction of use of antibiotics is a major point in the war against antimicrobial resistance. VAP is the first cause of healthcare-associated infections in ICU and more than half of antibiotics prescriptions in ICU are due to VAP. Once the diagnosis of pneumonia under MV has been made, initiation of antibiotic treatment must be prompt but there is no clear consensus on its duration. In the case of a good clinical response to treatment, it has been shown in some situations that short course antibiotics can be effective without side effects and antimicrobial stewardship initiatives can be applied successfully and effectively to the management of Community Acquired Pneumonia (CAP). The hypothesis is that an antimicrobial stewardship is possible in the treatment of VAP with no increase in the rate of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. The objective is to investigate whether an antimicrobial stewardship for VAP based on daily assessment of clinical cure and antimicrobial discontinuation, if it is obtained, would be non-inferior in terms of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. This study will be a prospective, national multicenter (31 centers), phase III, comparative randomized (1:1), single-blinded clinical trial comparing two management strategies of treatment of pneumonia on the basis of two parallel arms: Experimental group: Antimicrobial stewardship based on daily clinical assessment of clinical cure. Control group: standard management: duration of appropriate antibiotic therapy for confirmed VAP according to guidelines.
A Phase 2a, randomized, double-blind, placebo-controlled, multiple ascending dose study in patients who are hospitalized with presumed pneumonia requiring supplemental oxygen therapy. The purpose of this study is to examine the safety, tolerability and efficacy of AV-001 Injection administration daily to the earlier of day 28 or EOT (day prior to hospital discharge). A total of 120 eligible patients (20 patients in each of cohort 1, 2 and 3 and 60 patients in cohort 4) will be recruited from up to 25 participating institutions/hospitals. Patients will be randomized in a 1:1 ratio to receive either AV-001 Injection or AV-001 placebo Injection, together with standard of care (SOC).
Colchicine acts upstream in the cytokines cascade by inhibiting the NLRP3 inflammasome while IL-6 receptor antagonists (tocilizumab) block the end result of the cytokines cascade. Hence, adding colchicine to tocilizumab with the aim of blocking the early and end products of the cytokines cascade, might reduce the risk of developing cytokine storm and hence the need for invasive mechanical ventilation and eventually death. Therefore, investigators aim to conduct an open-label randomized controlled trial to evaluate the efficacy and safety of adding colchicine to tocilizumab among patients with severe COVID-19 pneumonia in an attempt to reduce the rate of invasive mechanical ventilation and mortality. Investigators will include patients with severe COVID-19 pneumonia and already received tocilizumab according to local protocol. Enrolled patient will be then randomized in 1:1 to colchicine versus no colchicine. Patients will be followed up until discharge or for 30 days, whichever comes first. Data will be collected from electronic medical profiles. The primary efficacy outcome will be rate of invasive mechanical ventilation and will be determined using Cox proportional hazard model.
The purpose of this study is to evaluate different peptide biomarkers, variations in the microbiome and patterns in the bacterial transcriptome as prognostic or diagnostic biomarkers of VAP.
The protocol, in accordance with the objectives of ORCHESTRA project - Work Package 2, aims at investigating the characteristics and determinants of COVID-19 long-term sequelae. This goal will be reached through the harmonization of follow-up strategies across the participating cohorts to allow a standardized collection of data on COVID-19 long-term sequelae. The result will be a platform including a set of data and biomaterials from large scale international cohorts, that will be uniformly recorded, prospectively tracked and analysed. The ultimate goal will be that of providing evidence to contribute to the optimization and improvement of the management and prevention of COVID-19 sequelae. The follow-up will be organized in multiple levels of tests, according to the capability of each cohort, and will include questionnaires to collect demographic, epidemiological and clinical data, physical examination, radiological exams and biological sampling. The long-term follow-up will also allow the assessment of long-term immunological response to SARS-CoV-2 infection and its association to the vaccination and to different treatment strategies, including monoclonal antibodies.
This study aims to 1. To study the prognostic value of LUS in COVID-19 patients. 2. To assess the relation between Lung Ultrasonography Score and disease severity in COVID-19 Patients. 3. To assess the relation between Lung Ultrasonography Score and mortality in COVID-19 patients.
