Active clinical trials for "Sepsis"

Multiple center, open-label, PK study

Despite maintaining adequate mean arterial pressure and central venous oxygen saturation, the mortality is still high in severe sepsis and septic shock. Previous studies have demonstrated that derangements in microvascular flow play a role in sepsis-induced multiple organ dysfunction and death. Lipopolysaccharide (LPS) or endotoxin is a specific ligand for Toll-like receptor 4 (TLR4), it can induce the following reactions including excessive immune and inflammatory responses , oxidative stress , capillary leakage, endothelial damage, impaired arteriolar and venular vasoregulation, and activation of the coagulation cascade 8. Subsequently, these reactions can lead to microcirculatory dysfunction. Polymyxin B adsorber hemoperfusion (PMX) have been proved to reduce mortality of severe sepsis and septic shock. Since 1994 to 2007, more than 60,000 patients have received this treatment. In a systematic review, the results show that PMX therapy was associated with significantly lower mortality risk (risk ratio, 0.53; 95% CI, 0.43 to 0.65). In a prospective, multicenter, randomized controlled trial (Early Use of Polymyxin B Hemoperfusion in Abdominal Sepsis [EUPHAS]), the results show that SOFA scores improved in the polymyxin B group, and 28-day mortality was 32% in the polymyxin B group and 53% in the conventional therapy group. The investigators hypothesize that polymyxin B hemoperfusion can decrease blood endotoxin level and reduce endotoxin-related microcirculatory dysfunction. The purpose of this prospective, multicenter, randomized, controlled, open study is to investigate the effect of polymyxin B hemoperfusion on the sublingual microcirculation in patient with proven or suspected gram-negative bacteria severe sepsis and septic shock. The mean arterial pressure, dose of vasopressors and inotropics, SOFA score, PaO2/FiO2 ratio, and 28-day mortality will be investigated.

This study is an evaluation of the effect of ketanserine on sublingual microcirculation in intensive care patients with severe sepsis.

Severe sepsis/septic shock is a serious condition associated with high mortality rate. Hydrocortisone has been recommended as a useful treatment to decrease mortality in hemodynamically unstable septic shock patients, not response to fluid and moderate dose of vasopressor. During the progression of severe sepsis/septic shock, multi-organ dysfunction can develop. Acute lung injury (ALI) and its more severe form, acute respiratory syndrome (ARDS) is one of the common organ dysfunction associated with septic shock. Information from a meta-analysis suggested that moderate dose of hydrocortisone may improve the ARDS patients' outcome. Whether hydrocortisone can effectively prevent disease progression and death in severe sepsis/septic shock patients who complicated with ALI/ARDS has not been proven.

The purpose of this study is to evaluate the pharmacokinetics of pioglitazone and to determine the effect on inflammatory biomarkers for pioglitazone in patients with severe sepsis and septic shock.

The motivation for this study comes from a desire to improve the mortality of patients with sepsis. Oxygen is cheap, readily available and is included in current United Kingdom Emergency Department guidelines, but it may also be harmful to patients with sepsis - it is important to know if this is the case. This study is a pilot study to also assess the feasibility of delivering a larger adequately powered study.

Investigators will assess the effect of exercise on markers of inflammation and protein catabolism. This research study will further our understanding of how treating Chronic Critical illness (CCI) - related respiratory muscle weakness with strength training can not only improve muscle function, but also potentially blunt the inflammation and catabolism of Peristent Inflammation/Immunosuppression and Catabolism (PICS).

This phase III multicentric international randomized trial is designed to compare the efficacy of Meropenem to the standard of care in infants below 90 days of age with clinical or confirmed late-onset sepsis (LOS). The aim is to assess efficacy , pharmacokinetics and safety of Meropenem which are not well known and documented in this population.

This study is a randomized control trial assessing the impact of a simple evidence-based protocol for the treatment severe sepsis with hypotension in Zambia. This is a follow-up study to the Simplified Severe Sepsis Protocol (SSSP) study. The intervention protocol consists of a scheduled fluid regimen, early blood culture and antibiotics, and dopamine and blood transfusion when necessary. It is hypothesized that the protocol will significantly decrease in-hospital mortality in patients with severe sepsis and hypotension.

By tradition hydroxyethyl starch (HES) is used to obtain fast circulatory stabilisation in critically ill. High molecular weight HES may, however, cause acute kidney failure in patients with severe sepsis. Now the low molecular weight HES 130/0.4 is the preferred colloid in Scandinavian intensive care units (ICU) and 1st choice fluid for patients with severe sepsis. HES 130/0.4 is largely unstudied in ICU patients. This investigator-initiated Scandinavian multicentre trial will be conducted to assess the effects of HES 130/0.4 on mortality and endstage kidney failure in patients with severe sepsis. The trial will provide important data to all clinicians who resuscitate septic patients.
