Infection

The VPT Safety Trial (VPS) compares two common antibiotic combinations to see how they affect the kidneys of patients in the hospital with serious infections. Both combinations are approved by the Food and Drug Administration (FDA). The goal is to help doctors know which combination is safer so they can make better choices for their patients.

Procalcitonin is a well-known biomarker used to distinguish between bacterial and viral infections, assess a patient's risk category, and serve as a prognostic indicator. However, existing data are derived primarily from relatively young patients in intensive care units; there is a lack of information regarding the prognostic significance of procalcitonin in older patients hospitalized in internal medicine wards.

This multicenter, cluster-randomized, unblinded quality-improvement study evaluates whether home-based clinical assessment by municipal acute care teams can safely reduce hospital admissions among nursing home residents experiencing acute illness or clinical deterioration during out-of-hours periods. Participating nursing homes in the Capital Region of Denmark will be randomized to either usual care (contacting the regional medical helpline, 1813) or the intervention pathway, in which nursing home staff contact a municipal acute care team directly. The acute care team performs an on-site clinical assessment and, when needed, consults a senior physician in the hospital emergency department to establish a treatment and observation plan, which may include continued management at the nursing home under hospital responsibility. The study compares the intervention with usual care with respect to hospital admissions and mortality among nursing home residents.

This protocol is being established to cover the evaluation of patients with inflammatory and/or infectious diseases which are not covered under previously existing protocols. The purpose of such a protocol is that frequently patients are referred to us with either diagnosed or undiagnosed illnesses which would be of interest to our teaching program or which would serve as a source of patients to subsequently be entered into established, ongoing protocol studies. Such patients will be admitted to the protocol and handled according to accepted medical practice of diagnosis and treatment.

The present study investigates the feasibility of a support pillow for use after spinal surgical procedures, and more particularly, to protect the midline region of the back following spinal surgery. Existing cushioning pillows do not accommodate the anatomy of the human back nor the requirements of isolating a vertical spinal incision. For example, donut-style or ring-shaped pillows are designed for entirely different purposes, such as hemorrhoidal relief, and cannot provide the desired spinal relief. As a result, there is no suitable, dedicated support structure that allows a patient to rest on their back while eliminating pressure on the surgical site. Accordingly, there is a need for a device that permits postoperative spinal surgery patients to sit or lie in a supine or reclined position without the surgical incision contacting or being compressed by any supporting surface.

This study seeks to develop early recognition tools specially designed for children meeting the Phoenix definition and explore implementation science aspects by investigating facilitators and barriers to adopting Phoenix sepsis criteria in clinical practice. This addresses the critical need for systemic, evidence-based approaches to paediatric sepsis identification across diverse healthcare settings in Asia.

Background: CGD is caused by a gene mutation. For people with CGD, their cells cannot kill germs well, so they can get frequent or life-threatening infections. Researchers want to see if a new procedure can help a person s cells kill germs for a short time. It uses messenger RNA (mRNA) to deliver correct instructions for the gene mutation to the cells. Objective: To test a procedure in which mRNA is added to a person s blood cells. Eligibility: Males aged 18-75 with CGD with a mutation in the gene that makes the protein gp91phox. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Swab to test for strep throat Some screening tests will be repeated during the study. Participants will be admitted to the NIH Clinical Center hospital for at least 7 days. They will have apheresis. For this, a medicine is injected under their skin to prepare their white blood cells for collection. An IV line is placed into an arm vein. Blood goes through the IV line into a machine that divides whole blood into red blood cells, plasma, and white blood cells. The white blood cells are removed, and the rest of the blood is returned to the participant through an IV line in their other arm. The next day, they will get their mRNA-corrected cells via IV. They will be monitored for 3 more days. After discharge, participants will keep a symptom diary. They will be contacted weekly for one month, and then once a month. They will have a follow-up visit 3 months after the infusion.

Kidney transplant recipients take medicines that suppress the immune system to prevent rejection of the transplanted kidney. As a result, they have a high risk of infections, especially urinary tract infections (UTIs). Some of these infections can spread to the bloodstream and cause serious illness, hospitalization, loss of kidney function, or death. Currently, there is no established strategy to prevent these serious bacterial infections in kidney transplant recipients who are at highest risk. The PREDICT study is investigating whether a low daily dose of the antibiotic pivmecillinam can reduce the risk of bacterial urinary tract infections and bloodstream infections after kidney transplantation. The study focuses on kidney transplant recipients who have bacteria detected in their urine during the first month after transplantation, as previous research suggests that these patients have a particularly high risk of developing serious infections later. In this randomized, double-blind, placebo-controlled trial, 180 adult kidney transplant recipients will be assigned by chance to receive either pivmecillinam or a matching placebo from 1 to 6 months after transplantation. Neither participants nor study staff will know which treatment has been assigned during the study. All participants will continue to receive standard post-transplant care and monitoring. The main goal of the study is to determine whether prophylactic pivmecillinam can reduce the occurrence of infections caused by Enterobacterales bacteria, including urinary tract infections and bloodstream infections, during the first 6 months after transplantation. The study will also evaluate the effects of treatment on serious clinical outcomes, safety, quality of life, antimicrobial resistance, and long-term kidney transplant outcomes. The study hypothesis is that targeted antibiotic prophylaxis with pivmecillinam in kidney transplant recipients at increased risk of infection will reduce the incidence of Enterobacterales urinary tract infections and bloodstream infections during the high-risk period after transplantation compared with placebo.

The aim of this study is to apply a diagnostic test called 'metagenomic sequencing' to identify the involvement of potential infections in patients with ocular inflammation, where this hasn't been detected by currently available standard testing. For many people with ocular inflammation, no cause is ever found for their disease. In some cases, an infection or infectious trigger is suspected, but currently available tests are inadequate. Metagenomic sequencing can identify almost every globally known infection (bacteria, virus, fungi, parasites) in a sample. Therefore, it has the potential to identify an infection that has caused or triggered ocular inflammation, and as a consequence may help to identify specific treatments. It has the potential to improve our understanding of how to diagnose and treat people with this problem. This study will allow us to test the technique that has been previously optimised for brain infections, on ocular fluids. Participants will be 18 years of age or over and have active ocular inflammation which is suspected to be due to an infection, or an autoimmune process which has been triggered by an infection, but identification of this infection has not been possible using the investigations available as part of standard NHS care. Participants will be identified by the treating clinical team as requiring a sample of fluid from inside of the eye, and some of this fluid will be sent for metagenomic sequencing alongside standard testing. This study will be conducted at Moorfields Eye Hospital, London and will last for approximately a year. Participants will undergo additional non-invasive ocular imaging on the day of their clinic visit, but will not have to attend any additional research visits.

Drone-related combat injuries have become one of the most devastating mechanisms of injury in modern warfare. These injuries often cause extensive tissue devitalization, contamination, open fractures, vascular injuries, and complex soft tissue damage, which may substantially increase the risk of severe wound infection, multidrug-resistant bacterial infection, repeated surgical procedures, limb loss, and sepsis. However, the relationship between the extent of tissue devitalization and the development of severe infection has not been systematically investigated. The DRONE-WOUND Study is a prospective observational cohort study designed to evaluate the association between tissue devitalization and severe wound infection in patients with drone-related combat trauma. The study will collect detailed clinical, surgical, microbiological, and radiological data from injured patients treated at participating trauma centers. Measures of tissue injury, contamination, surgical management, microbiological findings, and infection outcomes will be analyzed to identify factors associated with severe infection and poor clinical outcomes. The findings of this study are expected to improve understanding of the mechanisms leading to infection after drone-related injuries, support early identification of high-risk patients, and inform future strategies for surgical management, antimicrobial therapy, and infection prevention in combat trauma. Ultimately, the study aims to improve limb salvage, reduce infectious complications, and enhance outcomes for patients with severe drone-related injuries.

The study will evaluate the performance, clinical benefits and safety of the Persona Revision Knee System in patients who have received primary or revision total knee arthroplasty (TKA) treatment. This will be done using a multicenter, single-arm, consecutive series, retrospective cohort study with prospective follow-up.

Urinary tract infections (UTI) are commonly encountered in children, with 7% diagnosed with at least one UTI by the age of 19 years. The evidence for treatment of uncomplicated UTI is clear; oral antibiotics are as good as intravenous (IV) antibiotics, usually for a total of 7 days. Complicated UTIs (cUTIs) on the other hand, are common reasons for hospital admissions for IV antibiotics and constitute a major burden for healthcare systems. There is considerable variation in care for children who present with UTI and have complicating features such as vomiting, dehydration, urological abnormalities or have a previous history of UTI. Australian and international guidelines lack clear, evidence-based recommendations to guide treatment in this group. Without gold standard evidence, these children will continue to receive unnecessary IV antibiotics, longer hospital stays and poorer health outcomes. This multicentre, non-inferiority randomised trial will investigate if One dose - single dose of IV followed by 2 days oral antibiotics is as non-inferior to Three doses for children with UTI and co-existing complicating factors presenting to the Emergency Department (ED). In other words, this study will compare if a single dose of IV antibiotics plus two days oral antibiotics is as clinically effective as 3 doses antibiotics in resolving UTI symptoms at 72 hours after the first dose of IV antibiotics, for complicated UTIs in children presenting to the ED. All participants will receive a total of 7 days of antibiotics for the complicated urinary tract infection. If 1 dose IV and 2 days oral antibiotics is found to be as good as 3 days, the duration of IV antibiotics for complicated UTI can be reduced along with avoidance of the inherent risks of unnecessary hospital admission by administering a single IV dose in an outpatient/ED setting. On the other hand if a single IV dose results in prolonged symptoms or treatment failure, this will inform practice for the proportion of children who have a single dose of IV antibiotics in the ED and are sent home on oral antibiotics. Regardless of the outcome, this trial will inform clinical practice for complicated UTI to improve health outcomes for this group.

Cellulitis is a painful bacterial skin infection commonly seen in Canadian emergency departments. Cellulitis has a negative impact on patients' quality of life and productivity. While this is a bacterial infection, there is evidence inflammation also contributes to the disabling symptoms of pain, redness and swelling. Some studies have suggested that a nonsteroidal anti-inflammatory drug (NSAID) such as naproxen in addition to antibiotics may control inflammation and speed recovery. However, these studies have had too few patients to tell if there is a true benefit. The investigators are proposing a randomized controlled trial of patients with cellulitis to compare oral naproxen (500 mg twice daily) plus oral antibiotics versus placebo plus oral antibiotics. The investigators will compare the proportion of patients who have an early clinical response (reduction in area of redness ≥20% at 72 hours), cure, treatment failure, adverse events, and hospital admission. If naproxen proves to be superior to placebo, this simple, low-cost intervention will speed time to recovery with less pain for patients, and may potentially reduce treatment failure and time missed from activities. The results of this trial will help inform future cellulitis treatment guidelines.

The goal of this clinical trial is to learn whether integrating rapid multiplex molecular microbiology results with predefined clinical and laboratory criteria into an antimicrobial stewardship program improves antimicrobial use in hospitalized adults receiving empiric high-impact antimicrobial therapy. The main questions it aims to answer are: Does this strategy reduce the duration of exposure to high-impact antimicrobial therapy compared with standard antimicrobial stewardship practice? Does this strategy improve the appropriateness of antimicrobial treatment? Does this strategy affect clinical outcomes, including hospital readmission, intensive care unit admission, infection recurrence, mortality, and healthcare costs? Researchers will compare a protocolized antimicrobial stewardship strategy that incorporates multiplex molecular microbiology results and predefined clinical criteria with the standard antimicrobial stewardship strategy currently used in the hospital. Participants will: Receive antimicrobial management according to the stewardship strategy assigned to their hospital unit during the study period. Undergo molecular microbiology testing and routine clinical and laboratory assessments as part of standard hospital care when indicated. Be followed to evaluate antimicrobial exposure, treatment appropriateness, safety outcomes, hospital readmission, intensive care unit admission, infection recurrence, mortality, and healthcare costs.

The goal of this observational study is to learn how common infections are in intensive care units (ICUs) around the world and how they are treated. The study will look at all adults in the ICU during a single 24-hour period. The main questions it aims to answer are: * What types of infections and antibiotic-resistant bacteria are most common in ICUs worldwide? * How do resistance patterns affect how participants are treated and how they recover? How are antibiotics used in ICUs, and how do hospitals practice antibiotic stewardship? * What organ support treatments do participants with infections receive? * What are the outcomes of participants with severe infections, including survival at hospital discharge (up to 60 days)? Researchers will compare ICUs across regions and income levels to see how infection patterns, treatments, and outcomes differ around the world. Participants will: * Be counted if they are present in the ICU at any time during the study day. * Have information collected from their medical record about their health, the infection they may have, treatments they receive, and their outcome at ICU and hospital discharge (up to 60 days). Because this is an observational study, participants will not receive any new treatments as part of the study.

Aim The investigators aim to investigate if automated insulin delivery systems (AID) improve in-hospital glycemic and clinical outcomes in patients with type 2 diabetes compared to standard-of-care with a pen-basal-bolus insulin regimen manually titrated by general staff at Herlev-Gentofte Hospital and a clinical decision support system (GlucoTab) titrating the basal-bolus regimen automatically daily at Graz University Hospital. Population Hospitalized patients with type 2 diabetes in non-intensive care units (non-ICU) at medical wards at Copenhagen University Hospitals of Herley-Gentofte (affiliated with Steno Diabetes Center Copenhagen) and Medical University Hospital of Graz (N = 92). Design This is an investigator-initiated, two-armed, two-site, prospective, randomized, open-label, blinded endpoint (PROBE) trial. Objectives The objective is to determine the glycemic and clinical effects of inpatient AID systems in non-ICU patients with type 2 diabetes. Participants will be randomized in a usual-of-care and an AID arm. Diabetes management will be performed by usual care in the control arm based on a basal-bolus insulin regimen and point-of-care (POC) glucose testing. A continuous glucose monitoring (CGM) system (Abbott FreeStyle Libre 3) will be used in all groups for outcome analysis and comparison between the groups. The CGM will be blinded for the control arm, to not interfere with the usual of care because of the higher amount of glucose data. The AID-arm will be managed by an AID system with real-time CGM data transmitted to nursing stations. Outcomes Primary outcome: The primary outcome is the difference in CGM-recorded time in range (TIR) (70-180 mg/dl (3.9-10.0 mmol/l)) between the POC- and the CGM-arm according to the 2023 in-hospital CGM consensus during the entire hospital stay. Secondary outcomes: Outcomes are reported according to the 2023 in-hospital CGM consensus and specified in the protocol during the entire hospital stay, including three levels of time above range (TAR) 180-250mg/dl (10.0-13.9 mmol/l), \>250mg/dl (\>13.9 mmol/l), and \>180mg/dl (\>10.0 mmol/l); three levels of time below range (TBR) 54-70mg/dl (3.0-3.9 mmol/l), \<54mg/dl (\<3.0 mmol/l), and \<70mg/dl (\<3.9 mmol/l); events of hypoglycemia in three levels, 54-68mg/dl (3.0-3.8 mmol/l), \<54mg/dl (\< 3.0 mmol/l), and \<70mg/dl (\<3.9 mmol/l), where the glucose values between the two hypoglycemic events must all be \>70mg/dl (\>3.9 mmol/l) for at least 15 consecutive minutes(1), including prolonged hypoglycemic events (\> 120 minutes), recurrent hypoglycemic events (events preceded by another hypoglycemic event), and recurrent hypoglycemic days (percentage of days with at least one hypoglycemic event on separate days that is preceded by another in-hospital day with hypoglycemia(1)); mean glucose level; standard deviation (SD) of the CGM glucose distribution; coefficient of variation (CV); and insulin doses during hospitalization. Clinical outcomes: The investigator assess the length of hospital stay as calculated from time of admission until discharge; in-hospital mortality; admissions to intensive care unit; any in-hospital-related complications occurring at least one day after randomization and until discharge, as documented and defined by the treating physician in the electronic health record (e.g., acute kidney injurie, sepsis, etc.) Method For the usual-of-care-arm, glucose assessment is done by standard POC glucose testing and insulin is manually titrated by general staff at Herlev-Gentofte Hospital and the glucose assessment is done by standard POC glucose testing and insulin is manually titrated by the GlucoTab system titrating the basal-bolus regimen automatically daily at Graz University Hospital. For the AID-arm, CGM data informs in real time the mylife Ypsopump for automated insulin delivery. Device The investigational device is the AID system, containing of the mylife YpsoPump and the FreeStyle Libre 3 sensor.

This prospective multicenter validation study aimed to evaluate the predictive performance of a previously developed model for MDRGNB infection in ICU patients.

Long-term outcomes in kidney transplantation remain a significant challenge, as complications such as donor-specific antibodies (DSA), antibody-mediated rejection, infections, and cancer increasingly threaten graft and patient survival over time. The development of non-invasive biomarkers to guide the management of therapeutic immunosuppression beyond the first year post-transplantation is therefore a crucial unmet need. Torque Teno Virus (TTV), a non-pathogenic virus with a high prevalence worldwide, has emerged as a promising biomarker in this context. Its replication inversely reflects immune control by T cells, correlating with the depth of therapeutic immunosuppression. Additionally, its slow replication kinetics make TTV DNAemia a useful marker for evaluating patient adherence to immunosuppressive treatments. The TAOIST study tests whether longitudinal monitoring of TTV DNAemia every six months, starting from the second year after transplantation, can guide the personalization of immunosuppressive therapy. The primary endpoint is the time to the first occurrence of complications linked to inadequate immunosuppression, including dnDSA, biopsy-proven rejection, infection, cancer, or graft loss. Secondary objectives include evaluating the acceptability of TTV DNAemia among healthcare professionals and assessing its cost-effectiveness compared to standard care. An ancillary objective examines the link between TTV DNAemia and the immunosuppressant possession ratio (IPR) to explore its potential as a marker of treatment adherence.

This is a prospective, single-center Phase II observational study investigating the predictive value of the "Peripheral(-muscle) Oxygenation and Perfusion Score" (POP-Score), a novel non-invasive composite index, for early detection of infection/inflammation in neonates. The POP-Score combines peripheral muscle oxygenation measured via near-infrared spectroscopy (NIRS) with routinely monitored clinical parameters (heart rate, oxygen saturation, systolic blood pressure, and subcutaneous fat thickness). The study aims to determine the optimal cut-off value of the POP-Score measured within the first 6 hours after birth to predict elevated C-reactive protein (CRP ≥20 mg/L) within 48 hours. Additionally, multi-site NIRS measurements (cerebral, peripheral muscle, intestinal, and flank) will be evaluated to assess their association with inflammation. The study includes term and moderate-to-late preterm neonates (birth weight ≥2000g) with respiratory distress, admitted to the neonatal intensive care unit at the Medical University of Graz.

This study aims to ensure that assays that measure drug concentrations are accurate and precise in different matrices when quantified using high performance liquid chromatography -tandem mass spectrometry (HPLC-MS/MS). The study involves collecting samples of various bodily fluids to quantify antimicrobials, antivirals, oral contraceptives and erectile dysfunction agents. Samples will also be obtained from individuals not receiving these medications for quality control purposes.

Continuous intravenous antibiotic infusion using elastomeric pumps is well established in adult care and has been shown to be effective, safe, and cost-efficient, particularly for beta-lactams and vancomycin. In pediatric outpatient parenteral antimicrobial therapy (p-OPAT), home intravenous treatment is feasible and safe, improves quality of life, and reduces hospital stays and healthcare-associated infections. Elastomeric pumps offer practical advantages, including portability, ease of use, fixed infusion rates, and reduced drug handling, although they are limited by fixed flow rates and drug stability. This prospective study at Tampere University Hospital (Tays) will evaluate the safety and cost-effectiveness of 24-hour continuous antibiotic infusions in children between January 2026 and January 2029. Eligible pediatric patients requiring intravenous antimicrobial treatment and suitable for home care will be included. Indications include serious bacterial infections such as bacteremia, osteomyelitis, septic arthritis, neutropenic fever, cystic fibrosis-related infections, and foreign body infections. The study antibiotics are benzylpenicillin, cloxacillin, piperacillin/tazobactam, and vancomycin, administered via CE-approved infusion devices for home use. Children will receive continuous infusion either initially in hospital or directly from the emergency department if appropriate, with treatment duration and dosing comparable to standard intermittent regimens. Outcomes include safety, feasibility, cost-effectiveness, and patient-reported quality of life measured using PedsQL™. The study aims to determine whether continuous infusion can optimize pediatric antimicrobial care and healthcare resource utilization. Results will be published in peer-reviewed international journals.

In this study, patients presenting with acute infections at risk of developing sepsis will be followed in their home setting using wearables that provide (semi-)continue monitoring of vital signs as well as through follow up using a designated smartphone application. This is an innovative pilot study that will examine the potential of transmural care through telemonitoring for the first time in patients at risk for developing sepsis. By allowing for active follow-up of vital parameters in a transmural setting, this project aims to reduce the number of hospitalizations as compared to current practice. Furthermore, we aim to the number of patients referred to the emergency department after a visit at their primary care physician. Thereby, we aim to reduce the healthcare burden, yet providing the ability for rapid intervention in case of detarioration of patients, thereby reducing morbidity and mortality as well as associated costs.

The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.

Every country in the world is experiencing growth in both the size and the proportion of older persons. As a result of the changes, the profile and needs of people with medical illnesses have evolved. How care is delivered to patients has to keep pace with these changes, or patients will experience poor care at high cost and not have their needs met. A new model of care has emerged to meet these challenges: Acute Medical Unit. Despite considerable investment and popularity of this model, questions remain: (i) Who benefits most from this care model? (ii) How may these models be most effectively implemented for the best results? (iii) How effective are these models? Singapore is well-placed to answer these questions with its national healthcare system and excellent research institutions. The investigators plan to study how effective the model is by comparing patients with similar profiles exposed to both these care models compared to how hospital care is usually provided, looking for four differences: (i) how long patients stay in hospital, (ii) how often they use the emergency department (iii) quality of health (iv) cost. Additionally, the investigators seek to characterise patterns of health needs for this group of patients.

The goal of this clinical trial is to examine the success and safety of administering certain antibiotics (beta-lactams) given in a longer 3-hour infusion to children (0-17 years) who are critically ill and have severe infection. The main question it aims to answer is: Is the longer infusion more effective than the conventional short-term (0.5-hour-long) infusion? Researchers will compare the 3-hour-long infusion group to the 0.5-hour-long infusion group to determine whether the longer infusion can cure the infection earlier and whether it is equally safe. The doses are the same in the two groups. Only the duration differs until the patient receives the antibiotic. Participants will: * be given the required antibiotic drug in a 3-hour-long or in a 0.5 hour-long infusion. * be examined to make sure their blood drug levels are correct. This will require two blood tests. * be treated according to routine care and have examinations and blood tests performed.
