Filter by:BACKGROUND The association between mortality and hypoalbuminemia has been observed in several diseases. Nonetheless, the efficacy of albumin on survival in critically ill patients is controversial. Several meta-analyses have reported either negative, neutral, or beneficial effects of albumin administration. To clarify this controversy, a large multicenter prospective study has been performed, comparing the effects of 4% albumin vs. saline for volume replacement in critically ill patients. Although no difference in the overall mortality has been observed, a predefined subgroup analysis has shown a trend of longer survival in septic patients treated with albumin. As fluid replacement has been shown to be critical in sepsis, and based on both its primary (oncotic) and secondary properties (anti-inflammatory), it is conceivable that the use of albumin for volume replacement and for treating hypoalbuminemia may have a beneficial effects on survival of septic patients. OBJECTIVES Primary objective: to verify whether volume replacement with albumin (treated group) and its maintenance within plasmatic physiologic range (equal or above 30 g/l) improves survival of patients with severe sepsis of septic shock, as compared to crystalloids (control group). Secondary objectives: to verify the differences in organ dysfunctions, hospital and intensive care unit (ICU) length of stay between the treated and control group. METHODS About 1350 patients with severe sepsis or septic shock will be randomized to receive either albumin or crystalloids as fluid therapy. Volume replacement will be performed for both groups according to the early-goal directed therapy. Treated group will receive 60 gr albumin infusion after randomization, and 40-60 gr albumin daily infusion to maintain serum album level equal or above 30 g/l. Control group will receive crystalloids for the entire study; albumin administration will be allowed only when daily serum albumin level will be lower than 15 g/l. Patients will be treated until the 28th day after randomization or until ICU discharge, whichever comes first. EXPECTED RESULTS Primary outcomes: absolute risk reduction of overall mortality of 7.5% at 28th day, with a further control at 90th day, following randomization. Secondary outcomes: reduction of number and severity of organ dysfunctions (as assessed by the Sequential Organ Failure Assessment score), reduction of ICU and hospital length of stay.
Patients with severe infection can develop very low blood pressure. There are many mechanisms leading to this, and one of them appears to involve a hormone called vasopressin. In children as compared to adults, the mechanism and response to low blood pressure are different for reasons that are not clear. One possibility is the difference in the production and/or response to vasopressin. Vasopressin has become part of the treatment of children with low blood pressure in the setting of severe infection, when other treatment has failed, but its use is on the basis of animal and adult studies. The exact timing and dose is uncertain. In this research study, the patients will receive standard treatment for sepsis and septic shock, and the investigators will measure the blood levels of vasopressin and a related compound called copeptin (both are required to understand the mechanism of control involved). Blood will need to be taken from patients without any sepsis so as to be able to compare the values in health and in sickness. The patient groups the investigators have chosen for this are those children who will have blood taken anyway as part of their routine care. The aim of this study is to develop an understanding of the body's hormonal response (with respect to vasopressin) to severe infection in children. The long-term aim is to improve the care of critically ill children with severe infection by using the most appropriate dose of vasopressin at the most appropriate time.
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.
Simvastatin will attenutat IL-6 levels and lead to a more rapid shock reversal than placebo
The present study was conducted as a prospective, randomized, controlled study to compare: - the effects of norepinephrine and phenylephrine on systemic and regional hemodynamics in patients with catecholamine-dependent septic shock - to test the hypothesis that norepinephrine may likewise better preserve hepatosplanchnic perfusion versus phenylephrine in patients suffering from septic shock
This clinical study designed as a prospective, open labelled, multi-centre, RCT will be carried out to evaluate if direct hemoperfusion with polymyxin B immobilized fiber column (PMX) is superior to conventional medical therapy for sepsis, for patients with sepsis arising from abdominal cavity infection, accompanied by the failure of one or more organs. 120 patients (60 treatment/60 control) will be considered in this study. Those patients fulfilling inclusion criteria and not having exclusion criteria will be randomly allocated to one of two study groups. One group will be treated with PMX (PMX group) and the other will receive a "standard therapy" for sepsis (control group). All patients will receive full intensive care management, including fluid resuscitation, vasopressors, antimicrobial chemotherapy, ventilatory support, and renal replacement therapy, if required. Each patient will be followed up for 28 days after study entry.
Septic shock is a frequent and severe complication in cirrhosis. Current mortality rate ranges between 50 and 80% of cases. Refractory shock, hepatorenal failure and variceal bleeding are the main causes of death of these patients. Terlipressin administration could prevent these complications and improve survival in this setting. Aim: To evaluate the effects of terlipressin administration on hospital survival in cirrhotic patients with severe sepsis or septic shock. Methods: Prospective, open labelled, controlled trial evaluating 72 cirrhotic patients with severe sepsis or septic shock who will be randomized to receive terlipressin plus alpha-adrenergic drugs or only alpha-adrenergic drugs at shock diagnosis. Patients will be submitted to continuous systemic hemodynamic monitoring (S. Ganz catheter or Vigileo). Changes in vasoactive systems and cytokines levels will be also evaluated.
This study aims at comparing the efficacy and safety of recombinant human activated protein C to that of low dose of corticosteroids and at investigating the interaction between these drugs in the management of septic shock
The purpose of this placebo-controlled study is to determine if drotrecogin alfa (activated) treatment provides significant mortality reduction improvement in patients with septic shock compared with placebo treatment in patients receiving the current standard of care for septic shock. This study will also assess the effectiveness of drotrecogin alfa (activated) in reducing 28-day mortality in patients with septic shock and concomitant severe protein C deficiency.
We are performing a prospective, randomized, controlled trial of dopamine versus norepinephrine for septic shock. The trial will enroll patients with suspected or documented site of infection and having 2 out of the three SIRS criteria. Patients will also be receiving standard of care, early-goal directed therapy including but not limited to fluid resuscitation, appropriate and early antibiotics, source control and evaluation for drotrecogin alpha where deemed appropriate, while being supported for septic shock.
