Filter by:The purpose of this study is to determine if early application of CRRT will result in an improvement of clinical outcomes of burn patients during the early phase of sepsis
The purpose of this study is to explore the value of CD4+T lymphocyte subsets in cell immunity in the patients with sepsis.There are immunoparalysis in septic patients,the important player is the change of CD4+T lymphocyte,this immunoparalysis state contribute to the illness progress and outcome. Comprehend the change regularity of septic patients' cell immunity can guide fiter and correcter treatment.
The overall purpose of the study is to determine whether either of the Improved Response Polymorphisms (IRPs) individually predicts a differential DrotAA treatment effect in patients with severe sepsis and high risk of death. This will be an international, multicenter, "prospective-retrospective", nonrandomized, controlled, outcome-blinded, genotype-blinded, matched-patients study. No prospective enrollment or treatment of patients will occur under this protocol. Retrospectively collected clinical data and DNA samples will be analyzed for existing cohorts of patients with severe sepsis who were previously treated with DrotAA (treatment group) or not (control group) as part of their standard care in an ICU.
This study will investigate whether early exercise in critically ill patients will decrease inflammatory markers, increase pro-inflammatory markers and prevent loss of muscle mass.
The purpose of the study is to investigate the plasma levels of Soluble Urokinase Plasminogen Activator Receptor (suPAR) at the diagnosis and after treatment of sepsis, and to determine whether it has a diagnostic and prognostic value in late-onset neonatal sepsis.
Insulin regulates blood sugar and acts to suppress inflammation. Hyperinsulinemic Therapy is a protocol for Insulin administration that involves the administration of a calculated higher dose of insulin into the blood stream. This therapy is called dextrose/insulin clamp. It has been shown to be safe and successful in maintaining normal glucose levels. The objective of the study is to assess if the clamp can achieve a steady and normal blood glucose level in patients admitted to the intensive care unit with sepsis. Furthermore, if the higher insulin dose would lead to a drop in the inflammatory response seen in septic patients.
Sepsis is a clinical syndrome often caused by a bloodstream infection that results in a common set of symptoms termed systemic inflammatory response syndrome (SIRS). Severe sepsis (sepsis with organ failure) is the leading cause of death in critically ill patients in the US. Most patients with severe sepsis need to be treated in the intensive care unit with mechanical ventilation and intravenous antibiotics. Between 30 to 50% of all severe sepsis patients die and quality of life in survivors is substantially reduced. New therapies are needed to improve clinical outcomes in patients with sepsis. A new area of interest in the treatment of critical illness is pharmaconutrition, in which micronutrients (like zinc) are studied and administered to determine if they affect the inflammatory response or immunologic processes in critical illness. The FDA does not regulate micronutrients and does not require rigorous pharmacokinetic (the study of how a drug or nutrient is metabolized in the body) testing so it is not clear how to dose micronutrients in critically ill patients. It is also not clear if critically ill patients would metabolize these micronutrients differently than healthy people and would need different dosing levels. This is true of zinc, the focus of this research study. Zinc is essential for normal immune function, oxidative stress response, and wound healing, and its homeostasis is tightly regulated. Zinc deficiency occurs in >10% of Americans and leads to loss of innate and adaptive immunity and increased susceptibility to infections. The symptoms of zinc deficiency are similar to many of the symptoms of SIRS and there is strong biologic rationale to suggest that the zinc deficiency seen in nearly all sepsis patients may contribute to the development of sepsis syndrome and to the "immunoparalysis" common in sepsis patients This study has three specific aims, 1) to perform a phase I dose-finding study of intravenous zinc in mechanically ventilated patients with severe sepsis; 2) to define the pharmacokinetic of intravenous zinc in mechanically ventilated patients with severe sepsis compared to healthy controls; and 3) to investigate the impact of zinc on inflammation, immunity, and oxidant defense in patients with severe sepsis. A total of 40 critically ill patients from the FAHC intensive care units and 15 healthy controls will be enrolled in the study. The critically ill patient population will be divided into 4 dosing groups of 10 subjects (7 randomized to zinc and 3 to saline placebo). Group 1 will receive 500mcg/kg IBW/day elemental zinc in divided doses every 8 hours. If the 50th percentile of the normal plasma zinc range (110mcg/dL) has not been achieved in all patients by 7 days and there are no safety concerns, sequential groups of patients will receive increasing doses in 250mcg increments to the ceiling dose. Groups 2 through 4 will receive 750, 1000, and 1250mcg/kgIBW/day elemental zinc, respectively. Each participant will receive the intravenous zinc or placebo for a total of 7 days unless they die or leave the ICU earlier. Pharmacokinetic testing will be obtained from 40 of the critically ill subjects and in 15 healthy controls. Additional blood will be drawn during the infusion protocol to investigate the impact of zinc on inflammation, immunity, and oxidant defense.
Respiratory muscle dysfunction in critically ill patients is associated with elevated morbidity, including prolonged weaning from mechanical ventilation. The causes for respiratory muscle dysfunction in these patients is poorly understood and no effective treatment is available. The general hypothesis of the present study is that in critically ill mechanically ventilated subjects respiratory muscle dysfunctions results from loss of myosin induced by activation of proteolytic cascades.
The aim of the study is to assess the effect of short-term infusion of ketamine at analgesic dosage on the immune response, morbidity and mortality among patients suffering from septic shock. We hypothesize that ketamine will modulate the cytokine response to sepsis and reduce morbidity and mortality.
The purpose of this study is to evaluate the hemodynamic values of neonates that are healthy and those with various congenital heart diseases and sepsis by using echocardiography and USCOM.
