Active clinical trials for "Shock, Septic"

Septic shock remains a major public health problem in industrialized countries, with a mortality rate as high as 50%, largely related to multiple organ dysfunction. In addition to dysregulated inflammatory response, the pathophysiology of organ failures in septic shock involves ischemia-reperfusion processes. Remote ischemic conditioning is a therapeutic strategy for protecting organs against the detrimental effects of ischemia-reperfusion injury. The objective of the present study is to determine whether remote ischemic conditioning can limit the severity of organ failure in patients with septic shock.

In this prospective clinical study, the investigators compare the outcome and clinical course of consecutive septic participants treated with intravenous vitamin C, hydrocortisone, and thiamine (treatment group) with a control group treated in the investigators' ICU. The primary outcome is hospital survival. A propensity score is generated to adjust the primary outcome.There is 70 participants in each group.

The purpose is to demonstrate that vasoreactivity of patients with septic shock evaluated with dose-response curve is diminished in septic shock and ameliorated by activated protein C (APC). This amelioration is correlated to decrease of inflammation, decrease of reactive oxygen species (ROS) markers and increase of circulating catecholamines.

We performed a multicenter, prospective, randomized, double-blind, pilot study in four adult medical intensive care units. Patients presenting septic shock were rapidly administered one of two regimens of hydrocortisone, either a 50-mg intravenous bolus every six hours during seven days (200-mg group) or a 100-mg initial bolus followed by a continuous infusion of 300 mg daily for five days (300-mg group). Hydrocortisone was stopped abruptly at the end of treatment.

IgM-enriched immunoglobulins (IgGAM; Pentaglobin ® ) are new therapy for sepsis and septic shock since they support immune system especially in case of " immunoparalysis" . However IgGAM isn't commonly prescribed, few centres use it as routine in severe infections and there aren't any guidelines to determine how and when to use them. Microcirculatory dysfunction is a crucial aspect in the pathogenesis of sepsis-induced organ dysfunction, resulting in hypoperfusion and tissue hypoxia. Unpublished clinical data suggest a beneficial effect of IgGAM at microvascular level proved with near infrared spectroscopy and Vascular occlusion test (VOT). This study is a double blind phase II prospective randomised controlled trial that will include patients admitted to the Intensive Care Unit of the University Hospital "Ospedali Riuniti" of Ancona, after no more than 24 hours from development of severe sepsis or septic shoc. Patients will be randomized into two groups (treaties and controls): patients in group of the treaties will be submitted to infusion of IgGAM conjugate (Pentaglobin ®) at dosage of 250 mg/kg IV (5 mL/kg) per day (rate of 0.4 mL/kg/h), for 72 hours. The controls will receive equal amount of physiological NaCl solution (0.9%) as placebo. Neither the patient nor the staff nurses and MD will be aware of the group and of the treatment applied. IgGAM solutions or NaCl 0.9% will be provided by the hospital pharmacy in similar bags. The remaining treatments will not be changed in any way and will be at the discretion of the doctor who's in charge of the patient. All patients of the two groups will receive the optimal therapy for their conditions, according to good medical clinical practice (GMP), with appropriate antibiotic therapy, vasoactive and infusional therapy

The primary purpose of this study to evaluate the effect of two different doses of AZD9773 (CytoFab™) versus placebo on ventilator free days (VFDs) over the first 28 days after the start of dosing with AZD9773 in patients with severe sepsis and/or septic shock, who are already receiving appropriate standard of care treatment for sepsis.

Patients with blood poisoning - sepsis - often receive blood transfusions in the intensive care unit. The evidence that blood transfusion leads to improved outcome is limited and the blood may be harmful to some of these patients. To bridge the gap between clinical practice and evidence, a large randomised clinical trial is needed to document the efficacy and safety of RBC transfusion in these very sick patients

The investigators propose a dose finding study to determine the feasibility of Angiotensin II (AII) to increase mean arterial pressure in high-output shock. If AII can be shown to increase mean arterial pressure, this could lead to future pharmacologic development based on the AII hormonal pathway. The investigators propose a 20 patient, randomized, placebo-controlled, blinded study in the treatment of high-output shock. Patients with high-output shock and a cardiovascular SOFA (sequential organ failure score) score of > 4 will be eligible. In addition, patients must already be receiving cardiac output monitoring and have a cardiac index > 2.4 L/min/ 1.73 m2. Patients will be randomized to intravenous AII or saline in a blinded fashion. There will be 10 patients in each arm. This is a safety and dose finding feasibility study. The investigators are starting with a small cohort consistent with similar types of studies. The investigators estimate that ten patients in each arm will generate a basis for determining if there is sufficient signal for AII to improve blood pressure at the doses outlined. The primary endpoint in the study will be the effect of AII on the standing dose of norepinephrine which is required to maintain a MAP of 65 mmHg. Secondary endpoints will be the effect of AII on urine output, serum lactate, and creatinine clearance. 30 day post dose mortality will also be assessed. Subjects discharged prior to day 30 will be contacted by telephone for this assessment.

PiCCO has been widely used in critical care settings for several decades. Together with pulmonary artery catheter, it is regarded as the important tool for guiding fluid management in patients with shock or acute respiratory distress syndrome. However, its effects on patients' outcome remain untested. The investigators study is a pilot study that is designed to test whether the use of PiCCO will improve patients' outcome, as compared to those without PiCCO monitoring.

The purpose of this study is to compare the classical tactics in the treatment of septic shock (dopamine, noradrenalin and dobutamine) to the use of vasopressin as first choice pressor. Vasopressin seems to be an interesting alternative in the treatment of septic shock. To this date, available studies have showed that it could correct hyperkinetic syndrome and vasoplegia in septic shocks without noticeable side effect. It as been demonstrated that vasopressin improves renal function, as no effect on digestive organs and as no metabolic effect.
