Filter by:Many biomarkers have been evaluated in sepsis, especially for prognostic purposes, but none has yet been shown to have sufficient sensitivity or specificity for routine use in clinical practice. However, highlighting a biomarker facilitating the evaluation of the severity of sepsis remains relevant in a pathology where survival is largely conditioned by the initiation of an early and adapted treatment. Recent evidence suggests that hepcidin, which is the key hormone for systemic regulation of iron metabolism, may be an interesting prognostic biomarker. The synthesis of this peptide is regulated by the iron stocks of the body, erythropoiesis, but also inflammation. The mechanisms inducing the expression of hepcidin during inflammation are multiple: interleukin-6 (IL-6) in particular, pro-inflammatory cytokine is a strong inducer of hepcidin. In addition, its expression is increased by the effect of lipopolysaccharide via Toll-like receptors . In septic patients, elevated levels of hepcidin or pro-hepcidin have been reported . A new role for hepcidin in the control of inflammatory and / or immune response has recently been reported. Thus, in a model of murine septic shock, the deleterious character of a lack of expression of hepcidin could be demonstrated . In humans, hepcidinemia has been shown to be a predictive factor in the development of immunotolerance in hepatic transplant patients. Hepcidin therefore plays a major role in the regulation of the inflammatory and / or immune response and in particular during sepsis. The investigators therefore hypothesize that hepcidin could be the marker of an adverse prognosis in septic patients expressing this
Sepsis occurs when a serious infection - most commonly infection of the lungs, urinary system, or blood - leads to acute organ failure. It is a common, expensive, and frequently lethal condition. A growing body of evidence suggests that early recognition and treatment of sepsis can improve survival. Unfortunately, many patients with sepsis do not receive key therapies until physicians working in Emergency Departments have assessed them - often introducing marked delays. It is estimated that one-half of patients with sepsis are treated and transported to hospital by paramedics. This allows paramedics a unique opportunity to provide early treatment at the initial point of patient contact, thereby decreasing the time to treatment for these critically ill patients. This randomized controlled trial will evaluate whether prompt recognition followed by early antibiotics and/or intravenous fluids delivered by paramedics in the field leads to improved survival, compared to usual care, for patients who are transported to the hospital with sepsis.
Early and adequate fluid resuscitation (< 6 hours) in patients with circulatory failure is essential but may exacerbate oedema, which may itself: 1) aggravate pulmonary lesions and prolong mechanical ventilation, 2) aggravate organ failure and 3) increase mortality notably in patients with acute renal failure. Improving fluid balance is considered crucial in the management of patients in septic shock, but the efficacy of the measures currently proposed (diuretics associated or not with albumin and/or dialysis) is controversial. The investigators hypothesize that a whole-body compression using a body bandage could reduce capillary leakage and thus lead to faster restoration of a normal transmural pressure gradient in postcapillary venules and improve venous return. This is the first study to evaluate mechanical compression using a body bandage to reduce oedema in septic shock. To do this, a whole-body compression will be set up within the 12 hours following admission. Water balance will be monitored daily throughout the duration of the compression and vital status of patients will be search at 7 days, 28 days and 90 days.
We hypothesized that early exercise rehabilitation for patients with severe sepsis or septic shock would decrease their functional disability and cognitive impairment. We plan to enroll patients with severe sepsis and septic shock who admitted an urban teaching hospital in Seoul, South Korea via ER. We will randomize those subjects into the intervention group which will take a standardized rehabilitation with routine clinical care for sepsis and the control group which will take routine clinical care for sepsis. And, we plan to assess their functional activity using ADL, IADL and SF-36, and cognitive function using MMSE at the time of enrollment, 28 days, and 6 months later.
Observational studies among critically ill patients have shown strong associations between vitamin D deficiency and adverse outcomes, including increased length of stay, infection, and mortality. It is unknown whether vitamin D deficiency contributes directly to adverse outcomes or whether it is simply a biomarker of severity of illness or overall health status. However, vitamin D plays a key role in host defense, largely by stimulating production of the anti-microbial peptide cathelicidin (LL-37). We will test the hypothesis that administration of activated vitamin D (calcitriol) will increase serum levels of cathelicidin.
