Viromes in Infants Presenting With a Septic Syndrome

Fever in infants younger than 3 months is a common reason for emergency department visits and is associated with a significant risk of serious bacterial infections. Because it is difficult to distinguish bacterial from viral infections at presentation, management is often aggressive and includes invasive procedures, hospitalization, and empiric antibiotic therapy. Despite advances in molecular diagnostics, the etiology of fever remains unidentified in a substantial proportion of cases. This study aims to assess the presence of pathogenic viruses in respiratory and intestinal samples from febrile infants younger than 3 months compared with afebrile controls, and to explore associations with clinical, biological, environmental, and socio-economic factors

A Study to Evaluate the Immunogenicity and Safety of 13-valent Pneumococcal Conjugate Vaccine (PCV13i) in Healthy Infants Aged 2 Months (Minimum 6 Weeks)

This is a Phase 3 randomized, observation-blinded, active-controlled, parallel-group clinical trial designed to evaluate the immunogenicity, safety, and functional antibody response of the experimental vaccine versus the control vaccine in healthy Thailand infants vaccinated at a 2+1 schedule (2 months, 4 months and 12-15 months). The trial will enroll approximately 600 healthy infants aged 2 months (at least 6 weeks) who will be randomly assigned in a 1:1 ratio to receive either the experimental or control vaccine, with 100 in each group (200 in total) randomized to subgroups and subject to additional immunogenicity assessments. All participants will be evaluated for solicited adverse events for 7 days and unsolicited adverse events for 30 days post each vaccination. Immunogenicity evaluation will be performed in all participants at baseline and post the booster dose, while the sub-cohort participants will be evaluated for post primary series immunogenicity additionally.

Prospective Clinical Registry of Acute Treatment and Long-term Assessment of Children Meningitis

Prospective, multicenter, observational clinical registry of pediatric patients with acute infectious meningitis across approximately 20 public and private hospitals in Brazil. The study will include children under 18 years of age with suspected acute infectious meningitis. Data will be collected during hospitalization and post-discharge to evaluate clinical management, treatment and short and long-term outcomes. The study aims to generate real-world evidence on current practices and outcomes to support improvements in national care protocols.

Monotherapy vs Combination Therapy for Bone Infections Caused by Pseudomonas Aeruginosa

This study looks at how well one antibiotic (monotherapy) works compared to two antibiotics (combination therapy) in treating bone infections caused by Pseudomonas aeruginosa. It includes 300 adult patients who had this type of infection confirmed by lab tests and medical imaging. The goal is to find out if using just one antibiotic is as effective as using two, while also looking at side effects, the need for more surgery, antibiotic resistance, and overall antibiotic use.

The AcCREDiT 2 Study

The ACCREDIT study - Acute respiratory infections and chronic respiratory disease exacerbations characterisation and personalised treatment platform study 2 (AcCREDiT 2). Patients with respiratory infections (such as pneumonia) or exacerbations of chronic respiratory conditions (such as emphysema) often require hospital admission. Infections or exacerbation are commonly caused by bacteria, viruses or fungi. In at least a quarter of patients no infectious cause of the exacerbation is found. Depending on the cause of the respiratory infections or exacerbations of chronic respiratory condition patients require prompt treatment with anti-infective drugs (antibiotics, anti-fungal or antiviral drugs) or anti-inflammatory drugs such as corticosteroids. Patients with respiratory infection or exacerbations of chronic respiratory conditions develop symptoms such as cough, sometimes with sputum, fever or breathlessness. These symptoms can be similar across several conditions, many of which are not due to infection (for example heart failure or blood clots in the lungs). When assessing patients with respiratory symptoms, clinicians face the challenge of limited information in the early stages of care as it takes three days to identify infectious organisms in the laboratory. Even when an infection is strongly suspected, distinguishing bacterial from viral or fungal infections on clinical grounds alone is difficult. This uncertainty often leads clinicians to prescribe a number of treatments, including antibiotics, before a clear diagnosis is made. Timely treatment is crucial for success and improved patient outcomes, especially for critically ill patients admitted to the intensive care unit (ICU). However, antibiotics may cause side effects, such as sickness and diarrhoea, and overuse of antibiotics leads to antibiotic resistance, making antibiotics less effective when they are really needed. Giving antibiotics to patients with an infection or exacerbation and avoiding antibiotics in patients without an infection requires rapid diagnostic tests. Furthermore, giving antibiotics prior to taking samples to diagnose infection can affect the sample being tested making it more likely to not give a useful result. For a diagnostic test for infection to be most useful it needs to be collected before an antibiotic is given - this is true for both clinical tests and those research tests which are clinical tests in development. Modern technologies allow testing for an infection in hours rather than days. In order to understand how effective these technologies are, samples need to be taken from patients before they start treatment. In routine NHS care samples to test for infection should be taken before treatment has been started. However, in research studies samples are often taken up to a day after treatment has started which affects how effective the test is at finding infection. The forerunner to this study, called AcCREDiT, proposed investigating very rapid ways of identifying individuals with respiratory infection and exacerbation. However, the study team encountered challenges during the informed consent process, particularly with acutely unwell patients. Therefore, the AcCREDiT-2 was designed in collaboration with patients and public contributors to look at the feasibility of a modified informed consent process: verbal consent, assent for individuals with capacity to consent for themselves, and deferred consent. AcCREDiT-2 will be an observational study, meaning that no treatment will be changed, and no experimental drugs or tests used to influence the clinical care of participants. AcCREDiT-2 will also be a 'feasibility study', which is a smaller study designed to see what works well before embarking on a larger project. During the study the investigators will collect clinical information and samples, such as blood, sputum and stool, from patients who come to hospital with a presumed respiratory infection or exacerbation of their chronic respiratory condition. The investigators will compare new diagnostic tests to traditional laboratory tests to understand their relative advantages and disadvantages for patient care. This is a 'feasibility' study, a small study ran first to make sure things work properly before expanding to a much larger study.

Application of Bacterial DNA Quantitative Detection in Diagnosis of SBP in Cirrhosis: A Multi Center Diagnostic Experiment

Background and Significance: Spontaneous bacterial peritonitis (SBP) is a common and life-threatening complication in patients with liver cirrhosis, characterized by high incidence and mortality. The current diagnostic standard relies on ascitic fluid polymorphonuclear leukocyte (PMN) count ≥250 cells/μL. However, this threshold is associated with high rates of missed diagnoses, poor correlation with clinical symptoms, and delays in pathogen identification due to the low sensitivity and prolonged time of traditional ascitic fluid culture. With the development of molecular diagnostics, bacterial DNA (bactDNA) detection-especially through droplet digital PCR (ddPCR)-has emerged as a promising technique due to its high sensitivity, absolute quantification capability, and robustness. This study aims to evaluate the diagnostic value and accuracy of ddPCR-based quantification of bacterial DNA in ascitic fluid for SBP, providing a novel and objective diagnostic tool to improve early and accurate detection and to inform targeted antimicrobial therapy. Objectives: To assess the diagnostic accuracy (sensitivity, specificity, predictive values) of ddPCR-based quantification of total bacterial DNA in ascitic fluid for SBP. To evaluate the diagnostic performance of the ratio of Gram-positive to Gram-negative bacterial DNA (G+/G-) in predicting SBP. To explore the potential of ddPCR-based bacterial DNA quantification as a complementary or alternative method to conventional PMN-based diagnostic criteria. Study Design and Methods: This is a prospective diagnostic study involving 700 patients with liver cirrhosis and ascites. Ascitic fluid samples will be analyzed using ddPCR to quantify bacterial DNA levels. These results will be compared with traditional diagnostic criteria, including PMN counts and expert panel assessments based on clinical symptoms and laboratory findings. Statistical analyses will include correlation analysis, ROC curve analysis, and consistency testing. Expected Outcomes: The study aims to establish the clinical efficacy of ddPCR-based quantification of bacterial DNA in ascitic fluid as a novel diagnostic marker for SBP. This method is expected to be particularly useful in atypical cases where PMN counts are \<250/μL and may help guide preliminary antibiotic selection based on the proportion of Gram-positive and Gram-negative bacteria, thereby reducing empirical treatment failures and antibiotic resistance.

Integrated Clinical Decision Support for Empiric Antibiotic Selection in Sepsis

As antibiotic resistance increases globally, it becomes more difficult to select empiric antibiotic therapy, particularly in patients with sepsis who stand to benefit from early adequate treatment. In particular it is difficult for clinicians to balance antibiotic stewardship principles (the need to avoid unnecessary prescribing of antibiotics that have an excessively broad spectrum of activity that favour resistance development) and under treatment. The integration of multiple risk variables for resistance are hard for clinicians to translate into clinical action, and is seemingly at odds with the natural inclination to provide heuristic/emotion-based antibiotic selection. The inappropriate treatment of sepsis is not uniformly too broad, or too narrow, and there is a need to optimize and tailor selection of antibiotic therapy to each patient, such that those that are at risk for resistant organisms receive broad therapy, and those that are not at risk, receive narrower antibiotic agents. Clinicians need support picking the right antibiotic for each patient, and from this they can potentially drive reduction of unnecessarily broad antibiotic prescribing while preserving adequacy of treatment. Individualized clinical prediction models and decision support interventions are promising approaches that meet these needs by improving the classification of patient risk for antibiotic resistant or susceptible infections in sepsis. Unfortunately, few have been validated in the clinical setting and larger rigorous studies are needed to provide the evidence to support broader clinical adoption. The investigators will perform a cluster randomized cross-over trial of an individualized antibiotic prescribing decision support intervention for providers treating hospitalized patients with suspected sepsis. The aim of this trial is to determine whether a stewardship led clinical decision support intervention can improve antibiotic de-escalation in patients with sepsis while maintaining or improving adequacy of antibiotic coverage. This decision support intervention will be based on a combination of proven decision heuristics (for Gram-positive organisms) and modelled predicted susceptibilities (for Gram-negative organisms) that are individualized to the patient. The primary outcome will be the proportion of patients de-escalated from their initial empiric regimen at 48 hours.

Host Response to Infection by Direct Analysis of Leukocyte Single Cell-type Gene Expression/transcript Abundance, Direct LS-TA

Febrile illness is a common condition, particularly among young patients and it is crucial to have an early triage of patients according to various aetiologies to enable appropriate treatment. Most diagnostic tests are targeted towards the detection of pathogens while other assays are mostly related to serum proteins. Blood cells transcriptome has been explored to differentiate bacterial and viral infections. Here, we propose to develop a rapid test using the host responses in terms of gene expressions of single-cell populations of peripheral leukocytes (monocytes and granulocytes) to differentiate three major categories of infections that are bacterial, viral, and tuberculosis. The assay is called Direct leukocyte single cell-type transcript abundance (TA) assay (DIRECT LS-TA) as it can directly determine the gene expression of a specified single cell-type (e.g. monocytes and granulocytes) among various leukocyte cell populations directly in a peripheral blood sample. Such results signify the nature of host response and can be used to indicate the type of infection (viral, bacterial or active tuberculosis).

LázBarát™ (FeverFriend™) Projekt: Attitude Toward Fever and Its Change in the Healthcare System

The positive effects of fever are supported by a number of physiological, pathophysiological and clinical evidence. However, the negative attitude toward fever is widespread and have become persistent. According to sociological research, this is based on two main factors: comfort and fear. To change this negative attitude, awareness needs to be raised and the attitude toward fever among health care workers and the lay public needs to be reframed positively. Furthermore, the role of media users is essential, especially among the young generation. The current Hungarian recommendation/protocol is valid since 2011 (Professional protocol of the Ministry of National Resources: Caring for a child with fever, the recommendation of the College of Pediatric and Pediatric However, the practical implementation among health professionals and the laity public is low. Based on this protocol and current international guidelines (NICE) clinicians developed a protocol and register, where parents and caregivers can document the symptoms and runoff of fever as well as receive feedback on severity and appropriate management. The project aims to increase the evidence-based (EBM) guideline adherence, to reduce the unnecessary use of antipyretics and antibiotics, as well as the load on the current healthcare system. The documentation of the collected data allows the investigators to map and analyze (stats) socio-demographic behavior both on individual and societal level.

International Surveillance of Antimicrobial Resistance in Cirrhosis-Related Infections

What is this study about? This study tracks antibiotic resistance in patients with cirrhosis who develop bacterial infections. Cirrhosis is a condition where the liver is severely scarred, and people with cirrhosis are at high risk for serious bacterial infections. Why is this study important? Bacterial infections are common in patients with cirrhosis, affecting 25-46% of those who are hospitalized. These infections can be life-threatening, with 1 in 4 patients dying from complications. Many of these infections are becoming harder to treat because the bacteria are resistant to antibiotics. Infections caused by resistant bacteria are increasing, which makes finding the right antibiotic quickly even more difficult. In other regions of the world, guidelines exist to help doctors choose the right antibiotics for cirrhosis patients. However, in Latin America, we don't have specific guidelines for our region, and doctors currently rely on recommendations from the U.S. or Europe. These guidelines may not reflect the local patterns of bacterial infections and resistance we see here. What is the goal of this study? The main goal of this study is to create a long-term system to track how bacteria respond to antibiotics in patients with cirrhosis in Latin America. By collecting data from hospitals across different countries, we aim to: * Identify how many infections are caused by multidrug-resistant bacteria. * Understand how antibiotics (such as ceftriaxone, vancomycin, and carbapenems) act against these infections. * Generate reports informing bacterial resistance patterns to help doctors make better patient treatment decisions. What do we hope to achieve? We hope the data we collect will help develop guidelines for patients with cirrhosis in Latin America. These guidelines will ensure that doctors use the most effective antibiotics based on real-time data from our region. This should improve patient outcomes and help prevent the spread of resistant bacteria.

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.

A Cluster Randomized Controlled Trial to Compare the Rate of Antibiotic Infusion

Acute upper respiratory tract infection, commonly known as upper respiratory infection, is an acute inflammation primarily affecting the nose, pharynx, or larynx caused by various viruses and/or bacteria. Viruses are more common, accounting for 70% to 80% of cases, while bacterial infections account for 20% to 30%. For a long time, the high rate of intravenous infusion use has been a prominent issue in clinical diagnosis and treatment in China. The irrational and excessive use of antimicrobials in emergency patients with upper respiratory tract bacterial infections has also become increasingly apparent, imposing unnecessary financial burdens and risks of drug side effects on patients. Therefore, reducing the rate of intravenous antimicrobial administration in emergency patients with upper respiratory tract bacterial infections has become an urgent problem to be solved. By implementing measures such as health education by clinical pharmacists and enhancing the awareness of rational antimicrobial use in doctors, it is expected to lower the rate of intravenous antimicrobial administration, reduce the occurrence of drug resistance, improve treatment convenience for patients, and lower treatment costs while ensuring therapeutic efficacy. The purpose of this study was to investigate whether clinical pharmacists can reduce the intravenous infusion rate of antimicrobials in emergency patients with upper respiratory tract bacterial infections through medication education for emergency medical staff and to observe whether this intervention will affect the prognosis and medication safety of these patients.
