Filter by:This study seeks to elucidate the quantitative expression of G - protein receptor 43/free fatty acid (GPR43/FFA2) receptors in patients with the diagnosis of sepsis and specifically, its expression as it relates to the severity of sepsis. The investigators hypothesize that patients with more severe sepsis, as defined by a higher SOFA (Sequential Organ Failure Assessment Score), will have decreased expression of the GPR43/FFA2 as compared to patients with lower SOFA scores, consistent with a less exuberant immune response to infection. Patients admitted to Penn State Hershey Medical Center with a diagnosis of sepsis of any cause will undergo blood testing of leukocytes to determine the expressed quantity of GP43 during standardized time points of their illness and recovery. No interventions will be made in the standard clinical management of the patient. Additionally, healthy volunteers will be recruited to exam baseline GPR43 receptor expression between sepsis and control groups.
Sepsis induces hemostatic disorders due to the exessive or inappropriate activation of inflammation, which could lead either to hypercoagulability or hypocoagulability. It is currently not possible to determine the hemostatic status of a given patient. This instability of hemostatic system is not revealed by classical tests. Thus, a better characterization of hemostatic status could certainly improve patient care. This study aims at characterizing disorders of coagulation and fibrinolysis using "global" tests such as thrombin generation test or coagulolytic test. Furthermore, the association with biological markers of interest (such as microparticles, neutrophil elastase or histones) will be evaluated.
Sepsis is a common, expensive, frequently fatal and highly complex inflammatory syndrome wherein multiple cellular and humoral pathways are involved. Since it's a multifactorial syndrome merely blocking one of the various inflammatory pathways may not suffice to provide effective treatment and this may partly explain why most of the adjunctive therapies developed for severe sepsis have yielded disappointing results in rigorous clinical trials. Statins have varied pleiotropic effects on the inflammatory mediators and there addition to the current adjuvant therapies in septic shock may help in reduction of mortality. The present trial aims to study survival benefit and changes in bio-marker levels in septic shock. Adult patients (>=18 years) in septic shock and admitted to ICU will be included in the study. Patients will be randomized as per computer generated random number into the Drug (Atorvastatin, 40 mg) or matched placebo group. Drug or placebo will be given to selected patient via nasogastric tube for 7 days. Bio markers (Il-6, TNF-alpha) estimated during the trial week (Days 1, 4, and 7). All clinical and study personnel and patients remained blinded to the study group assignment throughout the trial.
The study aims at clarification of venous collapsibility measures with real venous flow measurements during dynamic maneuver testing fluid responsiveness in septic shock patients.
Purpose/Objectives: Severe sepsis and septic shock are a common cause of new onset atrial fibrillation (NOAF) in the intensive care unit. Development of NOAF in this setting can prolong length of stay and increase mortality. Amiodarone is the most commonly used agent used in this setting to control rate and rhythm. However, limited data exist detailing appropriate dosing in this setting. The primary objective of this study is to evaluate two amiodarone dosing strategies, a full loading dose versus a partial loading dose, in patients with new-onset atrial fibrillation (AF) due to severe sepsis or septic shock to assess the mean heart rate every 6 hours after initiation of amiodarone infusion to day 7 or death. Research Design/Plan: Consecutive patients admitted to the medical or cardiac intensive care unit at University Hospital with NOAF in the setting of severe sepsis or septic shock will be screened for study inclusion. Data will be collected and stored using Microsoft Excel or Access and analyzed with JMP 12.0 and SPSS. Methods: Patients aged 18 years or older who develop new-onset atrial fibrillation in the setting of severe sepsis or septic shock and in whom the medical team deems appropriate to initiate amiodarone therapy in will be considered for study inclusion. Patients will receive intravenous (IV) and oral (PO) amiodarone, as per the standard of care. Patients will be randomized to a certain quantitative loading dose strategy; either a full loading dose (≥ 5g IV or ≥10g PO +/- 20%) or a partial loading dose (<4g IV or < 8g PO). Clinical Relevance: With intensive care unit length of stay (ICU LOS) and mortality being twice as high in NOAF with sepsis as compared to septic patients without NOAF, the investigators ultimately aim to identify a management strategy that may minimize this morbidity and mortality while also minimizing exposure to a drug that may cause serious adverse effects.
IgM-enriched immunoglobulins (IgGAM; Pentaglobin ® ) are new therapy for sepsis and septic shock since they support immune system especially in case of " immunoparalysis" . However IgGAM isn't commonly prescribed, few centres use it as routine in severe infections and there aren't any guidelines to determine how and when to use them. Microcirculatory dysfunction is a crucial aspect in the pathogenesis of sepsis-induced organ dysfunction, resulting in hypoperfusion and tissue hypoxia. Unpublished clinical data suggest a beneficial effect of IgGAM at microvascular level proved with near infrared spectroscopy and Vascular occlusion test (VOT). This study is a double blind phase II prospective randomised controlled trial that will include patients admitted to the Intensive Care Unit of the University Hospital "Ospedali Riuniti" of Ancona, after no more than 24 hours from development of severe sepsis or septic shoc. Patients will be randomized into two groups (treaties and controls): patients in group of the treaties will be submitted to infusion of IgGAM conjugate (Pentaglobin ®) at dosage of 250 mg/kg IV (5 mL/kg) per day (rate of 0.4 mL/kg/h), for 72 hours. The controls will receive equal amount of physiological NaCl solution (0.9%) as placebo. Neither the patient nor the staff nurses and MD will be aware of the group and of the treatment applied. IgGAM solutions or NaCl 0.9% will be provided by the hospital pharmacy in similar bags. The remaining treatments will not be changed in any way and will be at the discretion of the doctor who's in charge of the patient. All patients of the two groups will receive the optimal therapy for their conditions, according to good medical clinical practice (GMP), with appropriate antibiotic therapy, vasoactive and infusional therapy
A Prospective, Multi-Centre, Double-Blind, Randomized, Placebo-Controlled, Trial of Ulinastatin Treatment in Adult Patients with Sepsis and Septic Shock in China
The aim of this study is to investigate the effects milrinon and levosimandan on n heart function in septic cardiomyopathy and how norepinephrine affects the left and right ventricular function in patients with septick shock using pulmonary artery catheter, conventional and strain echocardiography.
The fact that sepsis disrupts immune system homeostasis by inducing an initial cytokine storm, that participates to occurrence of organ failures and early death, followed by a compensatory anti-inflammatory response leading to immunosuppression, is now well established. This immunomodulating response results in a higher risk of secondary infections and is associated to 2/3 of deaths related to septic shocks. Follow up of patients' immune status with time is crucial to guide therapy management. Objective of REALISM project is to demonstrate existence of this immunosuppression phase, by providing strong epidemiologic data for septic shock patients, but also by extension to other situations of inflammatory aggressions like severe severe trauma or burns, or major surgery. This project will provide tools to predict occurrence of secondary infections and guide patient management by comparing innovating immunomonitoring tools to reference tests non already adapted to a routine patient management. Targeted populations are adult patients hospitalized for septic shock, severe trauma (including severe burn) or major surgery and healthy volunteers, whom blood samples will serve to validate reference intervals of the two reference tests.
The current treatment regimen of patients with septic shock requires a sufficient hemodynamic support aiming to preserve tissue oxygen requirements and perfusion. Therefore, aggressive fluid challenge and vasopressor agents play a pivotal role. To increase total peripheral resistance and preserve organ perfusion, a continuous infusion of catecholamines is often needed. Because sepsis is usually associated with adrenergic receptor and post-receptor abnormalities, the efficacy of such treatment regimens often gradually decreases over time, thereby complicating hemodynamic support. Experimental evidence suggest that α-2 agonists increase pressor responsiveness following lipopolysaccharide administration. This study will assess the effects of the sedation with dexmedetomidine (α-2 agonist) on norepinephrine requirements in patients with septic shock.
