Active clinical trials for "Sepsis"

In this before-after study, different new methods for bacterial species identification from positive blood cultures will be compared towards historic controls. All samples are analyzed within the routine workflow for bacterial species identification and antibiotic resistance profiling. Patients with positive blood cultures from 2016 to 2018 receiving a conventional identification methods (controls) will be compared to patients from 2018 and 2019 with a new identification method (cases). The conventional identification method consisted in general of an over-night subculture and subsequent identification of the bacterial pathogen using either biochemical profiling or Matrix-assisted Laser-Desorption/Ionization Time-of-Flight (MALDI-TOF MS). The new identification of positive blood cultures methods include (i) either the newly introduced Biofire FilmArray© Blood Culture Identification (BCID) panel or (ii) in a subset of patients whole genome sequencing (WGS) approaches.

Background: Despite management improvement in lasts years, S.aureus bacteremia leads to high morbidity and mortality. For over 50 years, methicillin-susceptible S.aureus (MSSA) bacteremia standard treatment was cloxacillin. Previous studies using different therapies and combination treatment fall to improve survival in these patients. Aim: to demonstrate the efficacy of the cloxacillin and fosfomycin combination administered during the first week of treatment, compared with cloxacillin monotherapy in patients with MSSA bacteremia in treatment success. Methods: A multicentre, superiority, open-label, randomized, phase IV-III, two-armed parallel (1:1) groups clinical trial. Adult patients with MSSA bacteremia will be randomized to Combination therapy group: patients will receive intravenous cloxacillin 2g/4h and fosfomycin 3 g/6h for the duration of 7 days treatment, or Standard therapy group: patients will receive intravenous cloxacillin 2g/4h for the duration of 7 days IV treatment. After the first week, antibiotic treatment and duration will be decided by responsible clinician following clinical practice. The primary endpoint is the treatment success measured at day 7 of treatment; a composite endpoint defined by all of the following criteria met after randomization: patient alive at day 7 AND stable or improved quick SOFA score (compared with baseline) at day 7 AND fever resolved at day 7 AND negative blood cultures for S. aureus at day 7. In case of achieving statistical differences in the primary endpoint, investigators will perform a hierarchical analysis of the treatment success at Test of Cure visit (TOC, 12 weeks after randomization), defined by the presence of all of the following: patient alive at TOC AND no evidence of microbiological treatment failure defined as isolation of S. aureus from blood culture or other sterile site from day 8 after randomization until TOC. Investigators have assumed a 74% of treatment success in monotherapy group. Accepting an alpha risk of 0.05 and a beta risk of 0.2 in a two-sided test, 183 subjects are necessary in first group and 183 in the second to find a statistically significant difference of 12%. It has been anticipated a drop-out rate of 5%. Discussion: Randomized studies assessing efficacy of different treatment in MSSA bacteremia are lacking. This study could help to improve knowledge about MSSA bacteremia and whether combined treatment with cloxacillin and fosfomycin could improve outcomes compared with standard treatment.

This phase II randomized study will assess the effect of receiving IV recombinant human IL-7 (CYT107) versus placebo in lymphopenic sepsis patients The aim is to confirm the immune cell reconstitution observed in other studies and other patient populations among which the IRIS-7 A&B study which was conducted in the same patient population.

Critical illness polyneuropathy and/or myopathy (CIPNM) is a severe complication of critical illness. Retrospective data suggest that early application of IgM-enriched intravenous immunoglobulin (IVIG) may prevent or mitigate CIPNM. Therefore, the primary objective was to assess the effect of early IgM-enriched IVIG versus placebo to mitigate CIPNM in a prospective setting.

Arterial catheterization is frequently performed on critically ill patients for invasive blood pressure monitoring and/or frequent blood draws, especially arterial blood gas analysis. The distal part of the radial artery (wrist) is the preferred access site. The potential complications of the procedure are mostly minor and comprise temporary occlusion of the radial artery (RA), hematoma, local infection or bleeding from the puncture site. Major complications including vessel aneurysm or occlusion with threat to hand viability are rare. The standard approach to catheterization is "blind" puncture of the RA while locating its pulse by palpation, followed by threading a 20 Gauge (20G) angio-catheter into the vessel. Alternatively ultrasound can be used to locate the vessel and guide needle insertion. To our knowledge, four prospective randomized trials (PRT)5-8 comparing palpation with ultrasound-guided RA catheterization have been conducted so far and one meta-analysis looked at the pooled data obtained from these. The results showed that ultrasound guidance increased the first-attempt success rate at RA catheterization by 71% compared to palpation. The use of ultrasound also significantly reduced the time to successful catheterization, the number of punctures as well as the amount of catheters required per procedure. None of the prior randomized trials has been conducted in an ICU setting and in three out of the four studies the arterial lines were placed in patients undergoing elective surgery. The investigators hypothesized that ultrasound could improve first attempt success rate while placing arterial catheters in an ICU setting. Ultrasound may also reduce total time to successful insertion and reduce complications. The investigators plan to randomize patients to either a palpation technique or ultrasound guided catheter insertion and record the above outcomes.

This study is a randomized control trial assessing the impact of a simple evidence-based protocol for the treatment severe sepsis in Zambia. The intervention protocol consists of a scheduled fluid regimen, early blood culture and antibiotics, and dopamine and blood transfusion when necessary. It is hypothesized that the protocol will significantly decrease in-hospital mortality in patients with severe sepsis.

We propose a Phase II, randomized, placebo-controlled clinical trial to test the hypothesis that treatment with once-daily statins has a beneficial effect on inflammatory cytokines and clinical outcomes in adults hospitalized with sepsis. As our animal models suggest pretreatment with statins are required for their beneficial effects, we propose a study design intended to identify patients and initiate treatment early in their hospital stay. This Phase II study is intended to assess the feasibility of conducting a large-scale investigator-initiated translational research protocol that involves multiple clinical services within the Department of Medicine.

Title: Study of Biomarkers in Blood and Alveolar Lavage Fluid Samples of Sepsis Patients Complicated With Acute Respiratory Distress Syndrome (ARDS) Research center: Single-center study. Design of the research: A prospective and cohort study. Object of the research: Patients（age≥18 years）those who meet the diagnostic criteria of sepsis complicated with ARDS and grouped into ARDS group and non-ARDS adults receiving mechanical ventilation as control. Sample size of the research: Not less than 30 patients in each group. Research approach: After admission to ICU, patients who meet the criteria are divided into mild group and moderate/severe group according to the severity of ARDS. In addition, blood and alveolar lavage fluid were collected within 24 hours for metabonomics analysis, and differential metabolites were screened out to prove the differentiation ability of differential metabolites between mild and moderate/severe ARDS patients. Then, MSEA and STITCH analysis were performed, and the relationship between different metabolites, HO-1 protein, oxidative stress and inflammatory markers in serum and alveolar lavage fluid were determined. And whether differential metabolites are associated with 28-day mortality in patients with moderate/severe ARDS. Aim of the research: The metabolomics techniques were used to compare the differences between sepsis patients with mild ARDS and moderate/severe ARDS. And determine the relationship between different metabolites, HO-1 protein, oxidative stress and inflammatory markers, as well as the predictive effect of metabolites on 28-day mortality in patients. Statistical analysis: Analytical study. The estimated duration of the study：1-2 years.

Severe sepsis leads a high morbidity and mortality by causing organ damage at distance. The treatment relies on early antibiotic therapy and hemodynamic resuscitation. Hypothesis: high flow nasal cannula (HFNC) could reduce work of breathing and improve the outcome of patients with severe sepsis and peripheral perfusion. Objective: the aim of this study is to evaluate the efficacy of HFNC for improving sixty-day survival in patients with severe sepsis. Design: multicenter parallel-group randomized clinical trial. Method: 592 adult patients with a diagnosis of severe sepsis in the first 12 hours of admission in the Emergency Room will be randomly assigned to an experimental or control group. In the experimental group, HFNC will be administered until the resolution of sepsis or until required mechanical ventilation, either invasive or non-invasive. In the Control group, conventional oxygen will be administered, if required. Sixty-day survival will be the primary outcome. The study is powered to demonstrate an improvement in survival from 70% in control group up to 80% in the HFNC group. The secondary outcomes will be reducing the need for vital support (mechanical ventilation, dialysis, vasoactive drugs) and physiological (acidosis, clearance of lactate, SvO2 and SOFA). Statistical analysis: Kaplan-Meier curves and Cox proportional hazard models will be calculated for all-cause sixty-day survival. If the results are conclusive, they will have immediate application in medical practice.

The majority of children and adolescents diagnosed with cancer will experience one or more episodes of fever or infection during their course of therapy. The most common microbiologically documented infection is bloodstream infection (BSI), which can be associated with severe sepsis or death. Current methods of diagnosis require a significant load of live bacteria in the blood making early detection difficult. Delayed diagnosis and delayed optimal therapy of BSIs are associated with increased morbidity and mortality. This study seeks to identify whether next generation sequencing (NGS) of pathogens can identify patients with impending bloodstream infection. This would enable preemptive targeted therapy to replace antibacterial prophylaxis which often leads ot high-density broad-spectrum antibiotic exposure and contributes to subsequent development of antibiotic resistance. PRIMARY OBJECTIVE: To estimate the sensitivity and specificity of next generation pathogen sequencing for prediction of bloodstream infection in children with cancer at high risk of infection.
