Adsorbtion of Cytokines Early in Septic Shock: the ACESS Study

SepsisSeptic Shock

The aim of the study is to investigate the effect of CytoSorb® treatment within the first 48 hours of septic shock on organ dysfunction, microcirculation and on the cytokine storm as monitored by leukocyte activation and inflammatory mediators.

Vasopressin Plasma Concentrations in Patients Receiving Exogenous Vasopressin Infusion for Septic...

Septic Shock

This is a prospective observational cohort trial evaluating a single plasma vasopressin concentration in patients receiving exogenous, adjunctive vasopressin for septic shock. The trial is designed to determine whether plasma vasopressin concentration influences the likelihood of hemodynamic response to exogenous vasopressin therapy.

Tryptophan, Serotonin and Kynurenine in Septic Shock

ShockSeptic

Septic shock is a major cause of mortality and morbidity worldwide. Serotonin (5-HT) is released by activated platelets into the circulation, and is mediator of endothelial dysfunction. 5-HT metabolism is known in immune system via specific 5-HT receptor, also in effects on the peripheral nervous system. Kinetic of 5-HT, tryptophan, kynurenine, MAO activity and IDO activity in human septic shock was never investigated.

The Validity of Peripheral Perfusion Index to Predict Fluid Responsiveness

Septic Shock

Fluid therapy is an essential component of the management of patients with acute circulatory failure. Nevertheless, unnecessary administration of fluids in non-responders is harmful. Thus, the concept of fluid responsiveness has been suggested to guide fluid administration in critically ill patients to avoid either over or under-transfusion. The aim of this work is to investigate the ability of peripheral perfusion index to predict the hemodynamic response to mini-fluid challenge in patients with septic shock .

Changes in Microvascular Perfusion During Blood Purification With Cytosorb® in Septic Shock

Septic Shock

Sepsis is defined as a life-threatening event due to a dysregulated immune response to an host. Blood purification techniques may be considered as a therapeutic weapon to front sepsis and septic shock. Haemoadsorption is one of the known blood purification technique that is employed in this study, and it is based on the principle that whole blood, contacting the surface of proper designed sorbent, would be cleared of certain substrates. With haemoadsorption it is possible to de-circulate from bloodstream high molecular weight substances, such as cytokines.In this study Cytosorb® cartridge, based on haemoadsorption principle is applied on septic patients, suffering for acute kidney failure, along with continuous veno-venous haemodialysis (CVVH-D).Microcirculation has a crucial role in the natural history of sepsis. In this prospective observational non interventional study, 10 septic patients with an acute kidney failure that need CVVH are enrolled. The primary endpoint of the study is to verify an improvement in the density of microcirculatory vessels and in the quality of blood flow after exposure to Cytosorb®. These two parameters are well described synthetically by the Perfused Vessel Density (PVD). As secondary endpoints we also want to analyze the modification of microcirculation after haemoadsorption therapy: microvascular blood flow, described by the microvascular flow index (MFI) and peripheral tissue oxygen perfusion during Cytosorb® exposure using near infrared spectroscopy technique (NIRS)

Next-Generation Sequencing Diagnostics of Bacteremia in Sepsis

SepsisSeptic Shock

Sepsis remains a major challenge, even in modern intensive care medicine. The identification of the causative pathogen is crucial for an early optimization of the antimicrobial treatment regime in patients with sepsis. In this context, culture-based diagnostic procedures (e.g. blood cultures) represent the standard of care, although they are associated with relevant limitations. Therefore, culture independent methods (e.g. Next-Generation Sequencing (NGS)) seem to be an attractive alternative. By the identification of circulating cell-free DNA in the blood and the use of the quantitative sepsis indicating quantifier (SIQ) score, causing pathogens can be identified and potential contaminations can be excluded. The goal of the presented study is therefore, to assess the diagnostic performance of a NGS-based approach for the detection of relevant infecting organisms in a big cohort of septic patients (n=500). Moreover, the plausibility of this NGS-based approach will be estimated by a panel of independent clinical specialists, retrospectively identifying potential changes in patients´ management based on NGS results.

Effects of Hydrocortison Treatment on Angiotensin II and Angiotensin II Receptors in Patients With...

ShockSeptic

This study aims to evaluate the role of angiotensin II, AT1, and AT2 on catecholomine responsive and catecholomine resistant septic shock, and the effect of hydrocortisone traetment on catecholomine resistant septic shock and angiotensin II, AT1, and AT2.Angiotensin II can be used as a biomarker of vasoplegia observed in refractory septic shock unresponsive to catecholamine. In these patients; therapeutic effect of hydrocortisone on hypotension was performed by decreasing AT 2 level, AT2 should be investigated as a therapeutic target in the treatment of vasoplegia-induced hypotension and SVRI measured by minimally invasive cardiac output method suggests that it can be used as a useful parameter in the diagnosis and follow-up of vasoplegia.

PK Analysis of Piperacillin in Septic Shock Patients

Septic Shock

Antibiotic dosing in septic shock patients poses a challenge for clinicians due to the pharmacokinetic changes seen in this population. Piperacillin/tazobactam is often used for empirical treatment, and initial appropriate dosing is crucial for reducing mortality. We determined the pharmacokinetic profile of piperacillin 4g every 8 hour in 15 patients treated empirically for septic shock. A PK population model was established with the dual purpose to assess current standard treatment and to simulate alternative dosing regimens and modes of administration. Time above the minimal inhibitory concentration (T>MIC) predicted for each patient were evaluated against clinical breakpoint MIC for Pseudomonas aeruginosa (16 mg/L). Pharmacokinetic-pharmacodynamic (PK-PD) targets evaluated were 100% f T>MIC and 50% fT>4xMIC.
