Active clinical trials for "Shock, Septic"

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.

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.

This is the statistical analysis plan for an individual patient data meta-analysis (IPDMA) of three EGDT clinical trials.

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.

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 .

The study aimed to assess the effectiveness of intravenous thiamine as compared with placebo in reducing the lactate level in septic shock patients.

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.

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)

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.

During infections (sepsis) bloodflow in small vessels (microcirculation) becomes disturbed. Restoration of bloodpressure and cardiac performance may not be sufficient to correct these alterations. Magnesium is a potent vasodilator which may be used to open up the small vessels, in order to reduce organ failure.
