Dose-response Study of Arginine Supplementation in Severe Sepsis
SepsisSeptic ShockPilot data in patients and data from pig studies indicate that arginine-NO metabolism is impaired in sepsis with changes in splanchnic metabolism and function, and reduced survival at low nitrate levels. Prolonged intravenous supplementation of L-arginine proved effective in pigs for increasing NO production, restoring gut function, and inhibiting an increase in pulmonary arterial pressure, without any deleterious systemic side effects. Prolonged intravenous L-arginine supplementation could therefore be useful in septic ICU patients.
Impact of CVVHD With Adsorption Capacity Membranes in Septic Acute Kidney Injury
SepsisSeptic Shock1 moreSeptic patients with acute kidney injury (SA-AKI) requiring continuous renal replacement therapies (CRRT) present high mortality due to systemic inflammatory response, cytokine liberation, and finally multiorgan dysfunction. Cytokine plasmatic elimination with continuous venovenous hemofiltration (CVVH) presents frequent complications, known as "dialytrauma", and a high resource cost both technical and human. The study primary end-point is to demonstrate a longer filter life with the use of continuous venovenous hemodialysis (CVVHD) respect to CVVH, both modalities employing the same adsorption capacity membrane. As secondary end-points investigators will try to demonstrate less dialytrauma events of CVVHD respect to CVVH. In order to achieve these objectives investigators have designed a proof of concept exploratory trial that will include those patients whom present SA-AKI meeting CRRT initiation criteria. During the first 72 hours investigators will measure plasmatic elimination capacity of main cytokines, and other clinical and prognostic relevant molecules. Investigators will also measure hemodynamic, respiratory, and metabolic parameters. Adverse effects related to CRRT ("dialytrauma") will also be registrated. Finally, investigators will analyze 90 days survival. Demonstration of a minor complication rate (longer filter patency with less dialytrauma events) with a similar immunomodulating capacity and with its consequent lower cost, should settle the based evidence principles that recommend the use of CVVHD asociated to an adsorption capacity membrane in patients with SA-AKI whom need CRRT.
Effects of External Inspection on Sepsis Detection and Treatment
SepsisExternal inspections are widely used as means to improve the quality of care. Despite their widespread use, there is limited knowledge about whether and how they affect the quality of care. This study uses inspection with detection and treatment of sepsis in hospitals as a case to evaluate the effect of inspections on the quality of care and to explore how inspections affect the hospitals.
Dysfunctions of Human Muscle Stem Cells in Sepsis
SepsisSevere critical illness is often complicated by Intensive Care Unit - Acquired Weakness (ICU-AW), which is associated with increased in and post-ICU mortality, with delayed weaning from mechanical ventilation and with long-term functional. Several mechanisms have been incriminated in the pathophysiology of ICU-AW, but muscle regeneration has not been well investigated in this context, even though its involvement is suggested by the protracted functional consequences of ICU-AW. Recent data suggest that muscle regeneration could be impaired after sepsis, and that Mesenchymal Stem Cells (MSCs) treatment could improve the post-injury muscle recovery.
Pharmacokinetics/ Pharmacodynamics (PK/PD) Study of Vancomycin
Blood Stream InfectionsEndocarditis1 moreDrug resistance of G+ cocci is a severe healthcare problem. According to the Ministry of Health National Antimicrobial Resistant Investigation Net (mohnarin) surveillance report, the isolation rate of MRSA is some 60% in China. MRSA infection has become a serious clinical problem; Vancomycin is a bactericidal glycopeptide antibiotic which inhibits bacterial growth by hindering the synthesis of cell wall in bacteria. It exerts strong antibiotic effect to Gram+ bacteria. It is indicated for serious staphylococcus infections especially MRSA infection and has become the gold standard agent in MRSA treatment; Vancomycin is a time-dependent antibiotic, its clinical and microbiological efficacy is related to area under curve( AUC)/minimum inhibitory concentration (MIC )(AUIC). Cmin at steady state is an surrogate parameter of AUIC, which is closely associated to the efficacy; AUIC >400 and Cmin between 15~20 mg/L are recommended for effective vancomycin treatment by Infectious Diseases Society of America (IDSA) although it is still disputable; Due to the absence of PK/PD study on vancomycin in China, administration of vancomycin is performed in reference to the recommendation of IDSA. Its suitability to Chinese patients is still to be clarified; Plasma concentrations of vancomycin vary significantly between population and individuals. Factors such as large-volume fluid infusion, hypoproteinemia and renal clearance, etc. will influence the distribution and excretion of vancomycin, resulting in different plasma concentrations between individuals. Results of PK studies differ greatly between China and abroad. Administration based on the AUIC or Cmin recommended by IDSA would not be suitable to Chinese patients. Given the definite long-term benefit of vancomycin treatment, the AUIC or Cmin suitable to Chinese patients must be identified by clinical study. The PK/PD study on vancomycin in the treatment to MRSA septicemia and endocarditis is of great significance for more reasonable use and improved therapeutic efficacy of MRSA infection.
Randomized, Multicenter, Double-blind, Vancomycin-controlled Study to Evaluate the Efficacy of Ethanol...
Lock SolutionCatheter Related Blood Stream Infections3 moreImplantable venous access port infections are mainly due to coagulase negative staphylococci and may be managed by antibiotic lock therapy with retention of the port. Most of the time a vancomycin lock is used. Experimental data show that vancomycin may be poorly effective in eradicating the staphylococcal biofilm in the port. Another disadvantage of Vancomycin-containing lock solution is the occurrence of resistant organisms and the risk of catheter occlusion. Ethanol-containing lock solution is highly effective in vitro and does not expose to the risk of emergence resistance.
Lactate Clearance Goal-directed Therapy in Sepsis
SepsisSerum lactate level is depended on the balance between lactate production and clearance. It is seen as a sensitive indicator reflecting not only the low systemic perfusion but microcirculatory dysfunction which cause global or regional tissue hypoxia (as a result of impaired mitochondrial oxidation). 2016 Surviving Sepsis Campaign guideline stated "We suggest guiding resuscitation to normalize lactate in patients with elevated lactate levels as a marker of tissue hypoperfusion", with weak recommendation and low quality of evidence. Several trials which evaluated the resuscitation strategy included lactate clearance as a target while based on 2.0 diagnostic criteria for sepsis, finally showed conflicting results. The aim of this study is to explore the feasibility of lactate clearance guide resuscitation in sepsis that defined by The Third International Consensus Definitions for Sepsis and Septic shock through multi-center, central-randomization clinical trial.

SepsisDisseminated Intravascular CoagulationThe primary objective of this study is to estimate the efficacy of unfractionated heparin(UFH) on ICU mortality in severe sepsis with suspected DIC.The Second objective is to estimate the effect of UFH on 28-day mortality,and the change of the Japanese Association for Acute Medicine(JAAM) score and SOFA score. The third one is to evaluate the safety of UFH in severe sepsis patients with suspected DIC.
