20% of trauma deaths occur late after the injury. It is usually the result of sepsis, multi-system organ failure, or other complications. In Polytrauma induced sepsis and septic shock patients, antibacterial management is crucial. The knowledge of recent aspects of treatment is decreasing the costs and the resistance of pathogens, morbidity and mortality. Different models of treatment are suggested by authors, basically they are depended on: the patients age, there health condition, the factors of immunodeficiency, at the location of infection and others...

Background: The prevalence of hypotension in emergency departments (EDs) is approximately 1-2%, but is associated with a mortality rate of 8-15%. There has never been a study in Thailand examining the epidemiology or the risk factors for early mortality of patients presenting with hypotension in the ED. Therefore, this study aimed to define the characteristics, mortality rate within 48 h and associated factors of hypotensive patients at ED. Methods: Data of patients with hypotension attending the ED of Thammasat University Hospital (TUH) were retrospectively studied...

Acid-base status is frequently assessed in severe sepsis and septic shock. Venous blood gas sampling is proposed as a less-invasive modality but lacks evidence within this population. The objective of this study was to evaluate the correlation and agreement between arterial blood gas (ABG), peripheral venous blood gas (pVBG), and central venous blood gas (cVBG) in severe sepsis and septic shock. We conducted a prospective, observational cohort study in subjects admitted to the medical intensive care unit. Simultaneous blood gas samples, including ABG, pVBG, and cVBG, were analyzed for correlation and agreement...

PURPOSE OF REVIEW: Temporary circulatory support (TCS) with short-term mechanical circulatory support (MCS) devices is increasingly used as a salvage therapy for patients with refractory cardiogenic shock. This article provides an overview of current devices, their indications and management, and discusses results of recent case series and trials. RECENT FINDINGS: Percutaneous active MCS devices (Impella, TandemHeart…) and venoarterial extracorporeal membrane oxygenation (VA-ECMO) are utilized as a bridge to 'decision' that includes weaning after cardiac function recovery, transplantation, long-term MCS and withdrawal in case of futility...

Sepsis with severe systemic inflammation remains a great challenge for the intensive care unit in clinics. Although biomarkers have been identified to diagnose, monitor and predict these syndromes, novel therapeutic approaches are required for the amelioration of symptoms of sepsis and septic shock. The present study demonstrated that interleukin (IL)-31 was able reduce the mortality rate of lipopolysaccharide (LPS)-induced sepsis with the reduction of inflammatory cytokines in the sera. IL-31 also inhibited IL-1β production in the peritoneal lavage fluid in LPS-induced or cecal ligation and puncture-induced sepsis...

We describe an extremely rare case of mediastinitis superinfected by emerging Achromobacter xylosoxidans. After mitral and aortic valves replacement, the patient first developed a Staphylococcus aureus mediastinitis, and five days after starting adapted antibiotic therapy, superficial pus analysis revealed the presence of Achromobacter xylosoxidans. This superinfection was considered superficial and focus was made on Staphylococcus aureus mediastinitis. Three weeks later, no more Staphylococcus aureus was found in pus samples and the sepsis seemed under control...

For years, procalcitonin (PCT) has been employed as a diagnostic biomarker for the severity of sepsis and septic shock, as well as for guiding the application of antibiotics. However, the molecular/cellular basis for the regulation of PCT production is not fully understood. In this study, we identified the signalling pathway by which the expression of PCT was induced by lipopolysaccharide in human hepatocytes at the mRNA and protein levels. This expression was dependent on nuclear transcription factor κB (NF-κB), as indicated by a NF-κB binding site (nt -53 to -44) found in the PCT promoter region...

BACKGROUND: We evaluated the effect of time spent in the emergency department (ED) and process of care on mortality and length of hospital stay in patients with sepsis or septic shock. METHODS: An observational cohort study was conducted on 117 patients who came through the University of Louisville Hospital ED and subsequently were directly admitted to the intensive care unit (ICU). Variables of interest were time in the ED from triage to physical transport to the ICU, from triage to antibiotic(s) ordered, and from triage to antibiotic(s) administered...

PURPOSE: Septic shock is commonly associated with hemostatic abnormalities. The endothelium-activated serine protease activated protein C (APC) plays a pivotal role in limiting coagulation and possesses anti-apoptotic and anti-inflammatory properties. We hypothesized that APC levels correlate with established coagulation parameters and provide prognostic information in patients with septic shock. METHODS: We conducted a prospective, observational cohort study in patients with septic shock...

BACKGROUND Systemic inflammatory response syndrome (SIRS) is characterized by systemic inflammation and tissue injury. Secondary sepsis is a common critical illness associated with poor clinical outcome. The aim of this study was to investigate the risk of SIRS-positive and SIRS-negative sepsis following gastrointestinal (GI) perforation. MATERIAL AND METHODS A retrospective study included 51 patients with GI perforation who had clinical evidence of sepsis, with or without SIRS. Clinical outcome was assessed at day 30 using the Glasgow Outcome Scale (GOS) (score, 1-5) and the sequential organ failure assessment (SOFA) (score, 1-6) to determine organ function...

Here, we report a case of a 67-year-old man who had septic shock due to Citrobacter braakii infection during the course of chemotherapy with high-dose cytosine arabinoside for acute myeloid leukemia. Treatment with cefepime rapidly improved his condition. The number of reported cases of sepsis due to Citrobacter braakii is limited. Further accumulation of cases is necessary to obtain accurate data such as the risk factors for Citrobacter braakii infections.

BACKGROUND: Human parechovirus (HPeV), like enteroviruses, usually causes mild self-limiting respiratory and gastrointestinal symptoms. In infants, HPeV can occasionally cause serious illnesses, including sepsis-like syndrome and encephalitis. In summer 2016, Public Health England (PHE) received increasing reports of severe HPeV infections nationally. We, therefore, reviewed all infants with confirmed HPeV across England during 2016. METHODS: HPeV cases in infants aged <12 months reported to PHE during 2016 were followed up using a clinical questionnaire...

BACKGROUND: Several studies have shown that long-term survival after acute kidney injury (AKI) is reduced even if there is clinical recovery. However, we recently reported that in septic shock patients those that recover from AKI have survival similar to patients without AKI. Here, we studied a cohort with less severe sepsis to examine the effects of AKI on longer-term survival as a function of recovery by discharge. METHODS: We analyzed patients with community-acquired pneumonia from the Genetic and Inflammatory Markers of Sepsis (GenIMS) cohort...
