Active clinical trials for "Shock, Septic"

Critically-ill patients frequently experience marked changes in mean arterial pressure and carbon dioxide partial arterial pressure, the two major determinants of the cerebral blood flow. In addition, many therapeutics (fluids, vasopressors or inotropes administration, blood transfusion, prone positioning...) can influence these two determinants of cerebral blood flow and thus cerebral blood flow, especially in patients with altered cerebral autoregulation. Nevertheless, cerebral hemodynamics and oxygenation, as well as the effects of the different therapeutics on it have been poorly studied in critically-ill patients. In addition, it has been suggested that impaired cerebral blood flow and impaired cerebral microcirculation may be involved in the pathophysiology of septic encephalopathy in patients with sepsis and/or septic shock. In this study, we aimed to characterize and investigate the effects of different therapeutics on cerebral hemodynamics and oxygenation in critically-ill patients.

In sepsis and septic shock, the host response is characterized by a complex of immune-inflammatory reactions; triggered and activated by microbial components. These reactions are controlled by a balance of pro-inflammatory cytokines and anti-inflammatory cytokines. The imbalance of this immune response is a source of organ dysfunction; major prognostic factor during septic condition. This pretext has created the need for therapies aimed to modulate the overstated of host response. During the past 2 decades, macrolide molecules proved interest to be immunomodulatory agents; due beyond their antibacterial activity. Their regulatory role in the production of cytokines was demonstrated in the management of severe acute community pneumonia. The investigators hypothesize that the adjunction of macrolides to standard therapy in patients with sepsis or septic shock is associated to a favorable immunomodulatory and clinical effects.

Septic shock is a subset of sepsis characterized by a decrease in vascular tone, which contributes to impaired regional blood flow distribution, and leads to organic failure. Besides intravenous fluids and adequate antimicrobial therapy, patients with septic shock require vasopressor support, which can lead to many adverse effects, therefore, non-vasopressor agents that can improve hemodynamic status are needed. In this randomized controlled-study, the investigators will address the efficacy and safety of infusion with methylene blue in patients with septic shock.

Since the ultimate target of resuscitation is the microcirculation, normal microcirculatory perfusion appears to be the primary target of ideal resuscitation in septic shock patients. In septic shock patients, microcirculation of the skin may be impaired in the early period due to early sympathetic nervous system activation. Assessment of skin perfusion has also become popular in shock resuscitation because it is easily accessible for clinical assessment. Studies in septic shock patients, showed that capillary refill time correlated with lactate levels measured at 6 hours of resuscitation and was associated with mortality. Additionally, early normalization of capillary refill time has been associated with improved survival in septic shock This study aimed to evaluate the relationship between the change in capillary filling time (microcirculation) and organ perfusion after fluid resuscitation in sepsis patients in intensive care.

The present study was conducted as a prospective, randomized study to investigate the effects of vasopressin receptor agonists terlipressin and vasopressin on systemic hemodynamics and microcirculation in patients with catecholamine-dependent septic shock.

The main purpose of this study is to test the safety of a new vaccine, STEBVax, which may lead to a useful treatment for toxic shock syndrome. The second purpose is to determine whether STEBVax causes the body to produce antibodies (proteins that fight infection) to help the body resist disease. Researchers expect STEBVax shots will cause the development of antibodies in the blood. Study participants will include up to 42 healthy adults, ages 18-40, from the University of Maryland Baltimore community. Participants will be assigned to one of 7 vaccine dose groups. Assignment to dosage groups will depend on when individuals are enrolled in the study. Study procedures will include blood sampling, urine collection, and physical examinations. Subjects will maintain a memory aid documenting daily oral temperatures and possible vaccine side effects. Participants will be involved in study related procedures for up to 201 days.

The purpose of this study is to investigate the effects on systemic hemodynamics, microcirculation and organ function of human Protein C concentrate in patients with sepsis and septic shock.

To compare the safety and efficacy of the PMX cartridge based on mortality at 28-days in subjects with septic shock who have high levels of endotoxin and are treated with standard medical care plus use of the PMX cartridge, versus subjects who receive standard medical care alone.

The two co-primary objectives of this study are to assess in Japanese patients with severe sepsis and/or septic shock: 1) the safety and tolerability of two different doses of intravenous AZD9773 and 2) the PK of AZD9773. The secondary objective is to make a preliminary assessment of the pharmacodynamics of two different doses of intravenous AZD9773 in Japanese patients with severe sepsis and/or septic shock.

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.
