Filter by:Septic shock is a clinical condition that is defined as a subset of sepsis that causes very high mortality and morbidity. Surviving sepsis campaign guideline states that the target mean arterial pressure should be 65 mmHg and above in septic shock patients. It is known that abdominal pressure increases and perfusion of intra-abdominal organs decreases in septic shock patients. With this study, we aim to investigate the effects of targeted abdominal perfusion pressure (60 mmHg and above) on renal injury, reversal of renal injury, liver functions and ultimately mortality in patients with septic shock.
Molecular testing is a largely validated approach allowing rapid identification of positive blood cultures. However, due to its high cost and its limited information on susceptibility, it is considered as an add-on technique reserved for specific patient populations. In our study, we specifically evaluated molecular testing in a critical care setting and measured its impact on the therapeutic management of critically ill with positive blood cultures. Through the analysis of 110 positive blood culture episodes included in both pre- and post intervention period, we measured a drastic 14h-reduction of the time to administration of the optimal antimicrobial treatment with the use of the molecular approach.
Implementation of the initial specimen diversion technique, in which the first milliliter of the venipuncture sample is not injected into the culture bottle, led to a significant reduction in blood culture contamination rates. This technique is based on the assumption that the skin plug aspirated during venipuncture is a major source of contaminating bacteria. One such diversion method is aspirating the first blood volume into a blood collection tube. It has, however, been suggested that regular blood collection tubes carry contaminants from the tube's stopper into the blood cultures drawn afterwards, thereby increasing contamination rates. The aim of this trial is to examine the effect of aspirating the first blood volume into a regular blood collection tube on blood culture contamination rate.
Prospective study at Duke University Hospital comparing the Karius Infectious Disease Diagnostic Sequencing Assay to blood culture results in admitted patients with bacteremia/septicemia.
This is a matched, open label study to evaluate the Initial Specimen Diversion Device (ISDD) in reducing the contamination rate in blood culture analysis. Blood culture data will be derived from inpatient and/or outpatient settings in a variety of hospital departments (e.g. ER, surgical, medical, etc.). Only samples that are collected via peripheral venipuncture may be included in this study. The ISDD will be compared to current laboratory practices for the collection of blood for culture purposes. Laboratory Standard Procedures (LSP) is defined as collection of venipuncture blood for culture without an initial diversion method to divert and sequester potential blood contaminants.
Listeriosis is a foodborne infection responsible for severe disease. Three main forms are described: septicaemia, central nervous system infections and maternal-fetal infections. Available data on the disease, are mostly retrospective and do not provide an accurate picture of the clinical / biological / genetic risk factors for the disease, nor identify any element to determine which patients are at higher risk of death, severe neurological impairment or fetal loss. The primary purpose of the study is to identify clinical, biological and genetic risk factors for systemic listeriosis and the determinants of listeriosis-associated mortality in the setting of a large prospective nation-wide study.
The purpose of the study is to evaluate and compare the immune response to two vaccines against 4 related bacteria: meningococcal serogroups A, C, W−135 and Y. These bacteria can cause meningitis and /or septicaemia (blood poisoning). The two vaccines are a protein−polysaccharide conjugate vaccine (MenACWY)and a meningococcal plain polysaccharide vaccine(MenACWY PS). Both vaccines are licensed and are currently used for travellers to areas with a high incidence of invasive meningococcal disease. However, plain polysaccharide vaccines are known to be poorly immunogenic in children and they do not stimulate immunological memory, apart from the serogroup A component. In contrast, a protein-polysaccharide conjugate vaccine against meningococcal serogroups A, C, W−135 and Y has been found to be immunogenic in infants and to be able to induce immunological memory. The proposed study is a single centre, open−label, randomised, controlled study in 150 healthy adults aged 18−70 years. The participants will be given either 2 injections of the meningococcal protein−polysaccharide conjugate vaccine one month apart, or one injection of the meningococcal plain polysaccharide vaccine followed one month later with an injection of the meningococcal conjugate vaccine. Blood samples will be collected before immunisation and at several time points following immunisations to evaluate the level of meningococcal specific antibody induced by two different vaccination regimes. The data derived from the study will be relevant in determining which of these vaccines should be used in preference in travellers who are receiving immunisation against meningococcal disease before travelling to high risk areas. Additionally, a number of scientific questions regarding the nature of the immune response to the two vaccines (specifically looking at the white blood cells responsible for producing antibodies, known as B cells) and the role of genetic variations in influencing the vaccine recipient's immune response will be addressed in the study.
The purpose of this study is to determine whether immunoadsorption of LPS, Il-6 and C5a reduces systemic hyperinflammation, improves immune function and improves organ function in patients with severe sepsis and septic shock
Sepsis is a serious condition where there is inflammation and damage to body tissue, usually caused by an infection. This infection can lead to decreased function of vital body organs and in some cases may lead to permanent health problems or death. Much of the injury is due to endotoxin, a harmful substance produced by certain types of bacteria. An endotoxin antagonist is designed to block the effects of endotoxin. This study is designed to study the safety and efficacy when treating patients with severe sepsis.
