Project 4A: Inspiratory Muscle Training and Diaphragm Strength
SepsisInvestigators 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).
Fluid Responsiveness Evaluation in Sepsis-associated Hypotension
SepsisHypotensionThis study assesses the mean difference in fluid balance at ICU discharge and associated patient outcomes, based on a dynamic assessment of fluid responsiveness in septic patients with refractory hypotension in an ICU setting.
Endotoxin Adsorber Hemoperfusion and Microcirculation
SepsisDespite 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.
The Effect of Ketanserin on the Microcirculation in Sepsis
Severe SepsisSeptic ShockThis study is an evaluation of the effect of ketanserine on sublingual microcirculation in intensive care patients with severe sepsis.
Efficacy of Hydrocortisone in Treatment of Severe Sepsis/Septic Shock Patients With Acute Lung Injury/Acute...
Septic ShockSevere Sepsis2 moreSevere 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.
Pharmacokinetic and Biomarker Study of Pioglitazone in Adolescents With Severe Sepsis and Septic...
Severe SepsisSeptic ShockThe 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.
Simplified Severe Sepsis Protocol-2 (SSSP-2) in Zambia
SepsisSevere Sepsis1 moreThis 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.

Immunomodulatory Properties of Ketamine in Sepsis
SepsisThe 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.
Efficacy, Pharmacokinetics and Safety of Meropenem in Infants Below 90 Days With Clinical or Confirmed...
SepsisThis 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.
