Filter by:The purpose of this study is to learn about the safety and effects of ATM-AVI for the possible treatment of infections caused by a type of bacteria called gram-negative bacteria. The study medicine is a combination of an antibiotic, aztreonam (ATM), and another medicine, avibactam (AVI), which is used to help stop bacteria from being resistant to antibiotics. Antibiotics are medicines that fights bacteria and infections. The study will include newborns and infants up to 9 months of age who are admitted in the hospital. The study is conducted in 2 parts: Part A and Part B. In Part A, all participants will receive a single intravenous (injected directly into a vein) infusion of ATM-AVI. This is to study the safety and effects of a single amount. In Part B, all participants will receive multiple intravenous infusions of ATM-AVI as treatment for a possible or confirmed infection with gram-negative bacteria.
Study Rationale: Previous in vitro and retrospective in vivo studies suggest that optimal linezolid concentrations (between 2 and 7 mg/L) achieve clinical efficacy and microbiological eradication while minimizing side effects like thrombocytopenia and the emergence of resistance. No prospective or randomized clinical trial has confirmed these findings, and there is no consensus on how to adjust linezolid dosing to achieve optimal drug concentrations. Objectives: The primary objective is to determine if model-informed precision dosing optimizes linezolid dosing to achieve therapeutic trough concentrations compared to a standard dose. Secondary objectives include assessing the PK/PD profile, investigating the prevalence of linezolid resistance among gram-positive bacteria, assessing microbiological resolution of infection, and evaluating the safety and tolerability of linezolid. Methodology: This study is an open, monocentric pilot randomized controlled trial with two arms: standard dose therapy versus dose adjustment based on model-informed precision dosing using therapeutic drug monitoring and PK/PD targets developed in TMDx software. Sample Size: 28 patients, 14 in each group. Assumptions are based on only 25% of patients in intensive care achieving the optimal therapeutic range with standard dosing, compared to an expected 80% achieving this with model-informed precision dosing. Selection Criteria: Adult patients (18+ years) already starting linezolid treatment for gram-positive infections, expected to require treatment beyond the next calendar day. Exclusions include imminent death, expected or confirmed pregnancy, expected linezolid treatment of less than 4 days or more than 4 weeks. Outcomes: The primary endpoint is defined as the difference in the proportion of patients in the intervention and in the control groups who maintained a trough linezolid concentration of 2 to 7 mg/L on Day 7 and Day 13.
CRAB infections in ICUs are on the rise, leading to higher morbidity, mortality, and healthcare costs due to resistance to most antibiotics, including carbapenems. The main resistance mechanisms include carbapenemases, efflux pumps, and changes in the bacterial cell wall. Current treatments include polymyxins (Colistin, Polymyxin B), which are effective but can lead to resistance, aminoglycosides (Amikacin, Gentamicin), which are limited by resistance, and tetracyclines (Tigecycline, Eravacycline), which are effective against CRAB. Fosfomycin is effective in combination treatments, and combination therapy (e.g., colistin with sulbactam, fosfomycin, or eravacycline) can enhance outcomes. Previous research shows promise for combination therapies, improving treatment efficacy and reducing mortality. New regimens are being studied to find optimal combinations. Individualized dosing is crucial, considering patient-specific factors like age, weight, and renal function. Adjustments depend on the infection site and comorbidities. Strict infection control and antimicrobial stewardship programs (ASPs) are essential. ASPs focus on optimizing antibiotic use and reducing resistance through education and surveillance. Future directions include continued research for new drugs or combinations and strategies to overcome resistance and improve treatment efficacy. Study goals include achieving negative samples after 10 days of therapy, 30-day survival, discharge rates, reduced SOFA scores, and improved clinical and radiological findings. A randomized study will compare colistin combined with fosfomycin, ampicillin/sulbactam, and eravacycline. In summary, treating CRAB infections is complex, requiring combination therapy, individualized dosing, and strict infection control measures.
Home Outpatient Parenteral Antimicrobial Treatment (Home-OPAT) is a service provided to patients that receive antibiotics via infusion but are clinically well enough to go home. A nurse will visit the patient daily to administer the antibiotics. However, the patient or a caregiver can also administer the antibiotics without the help of a nurse. This is called Self-OPAT. The Self-OPAT service is already in practice internationally but not yet in the Netherlands. The goal of this observational study is to assess the possibility to implement Self-OPAT in the Dutch context. The main questions it aims to answer are: Which patients are suitable for Self-OPAT services? How can patients be trained adequately for performing Self-OPAT? What are the experiences of patients with Self-OPAT? How much nurse engagement is needed during Self-OPAT? Is the outcome of treatment with Self-OPAT comparable to Home-OPAT? How do the costs of Self-OPAT differ from the costs of Home-OPAT? How can you implement an Self-OPAT program in the hospital? Participants will be trained by a nurse to administer the infusion antibiotics. They will then administer the antibiotics themselves for as long as the duration of treatment. Every week a nurse will visit to check the progression of the treatment and check the functioning and hygiene of the infusion materials. After a month participants will fill-out a questionnaire about their experience with Self-OPAT.
We seek to characterise the burden and outcomes of and understand the current experience of people who inject drugs admitted to hospital with invasive injecting-related infections, in order to implement and evaluate strategies to improve completion of therapy and reduce patient-directed discharges, with ultimate benefit to the patient and health service.
An anterior cruciate ligament (ACL) tear is one of the knee joint's most common soft tissue injuries [1]. It is frequently injured in non-contact and some contact competition sports and even during ordinary life activities. With an annual incidence of 68.6 per 100,000 person-years, ACL tears remain a common orthopedic injury [2]. Females are two to eight times more likely to develop ACL tears in sports compared to men who play the same particular sports [3]. Most highly demanding persons and those who develop frequent instability of their knee require reconstructive surgery on the ACL to prevent early degenerative changes in their knees. This is done by completely removing the torn or ruptured ACL and replacement with a piece of tendon or ligament (graft) [4]. Post-operative infection may occur in 0.14-2.6% of ACL reconstruction despite intravenous antibiotics prophylaxis [5,6]. The deep infection results in poor outcomes with pain, stiffness, arthrofibrosis, and articular cartilage degeneration [7,8]. Few studies reported improved outcomes of infection control when the autograft presoaked in vancomycin solution during the preparation process outside the body before being transferred to the knee of the patient [9-13]. Systematic reviews and meta-analysis showed that all the articles discussing the outcome of vancomycin presoaked autograft in ACL reconstruction surgery were case series, observational retrospective, prospective comparative, or case-control studies [14,15]. Randomized control trial (RCT) provides the strongest evidence among the primary research studies to confirm the effectiveness of a new method of treatment [16,17]. To date, there is no available RCT study in this field.

The investigators have developed an analysis AI for Gram staining. In this study, the investigators will compare the testing accuracy of automated Gram staining equipment with AI with the testing accuracy of laboratory technicians. Based on the results, the investigators will examine the possibility of clinical application of the automated Gram staining device.
This study is designed to evaluate the clinical and antibacterial efficacy, safety and pharmacokinetics of the drug Fluorothiazinone compared to placebo to prevent nosocomial gram-negative bacterial infections with participation of patients on mechanical ventilation. The main objectives of this study are: - Evaluation of the clinical and antibacterial efficacy of the drug Fluorothiazinone in combination with standard measures for the prevention of nosocomial infections compared to placebo in combination with standard measures for the prevention of nosocomial infections for the prevention of nosocomial infections caused by bacterial gram-negative flora in patients on mechanical ventilation. - Evaluation of the safety and tolerability of the drug Fluorothiazinone in patients on mechanical ventilation. - Evaluation of the pharmacokinetics (in whole blood) of the drug Fluorothiazinone with a single daily dose of 2400 mg/day. Researchers will compare results for the treatment and the placebo arms.
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 within 48 hours.
