A group of enzymes which catalyze the hydrolysis of ATP. The hydrolysis reaction is usually coupled with another function such as transporting Ca(2+) across a membrane. These enzymes may be dependent on Ca(2+), Mg(2+), anions, H+, or DNA.
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
Innate response elicited by sensory stimuli associated with a threatening situation, or actual confrontation with an enemy.
The artificial substitution of heart and lung action as indicated for HEART ARREST resulting from electric shock, DROWNING, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (RESPIRATION, ARTIFICIAL) and closed-chest CARDIAC MASSAGE.
Hybridization of a nucleic acid sample to a very large set of OLIGONUCLEOTIDE PROBES, which have been attached individually in columns and rows to a solid support, to determine a BASE SEQUENCE, or to detect variations in a gene sequence, GENE EXPRESSION, or for GENE MAPPING.
A strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective. It is relatively unstable and solutions deteriorate over time unless stabilized by the addition of acetanilide or similar organic materials.
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.

Enhanced Th1 activity and development of chronic enterocolitis in mice devoid of Stat3 in macrophages and neutrophils. (1/2106)

We have generated mice with a cell type-specific disruption of the Stat3 gene in macrophages and neutrophils. The mutant mice are highly susceptible to endotoxin shock with increased production of inflammatory cytokines such as TNF alpha, IL-1, IFN gamma, and IL-6. Endotoxin-induced production of inflammatory cytokines is augmented because the suppressive effects of IL-10 on inflammatory cytokine production from macrophages and neutrophils are completely abolished. The mice show a polarized immune response toward the Th1 type and develop chronic enterocolitis with age. Taken together, Stat3 plays a critical role in deactivation of macrophages and neutrophils mainly exerted by IL-10.  (+info)

Role of nitric oxide in lipopolysaccharide-induced hepatic injury in D-galactosamine-sensitized mice as an experimental endotoxic shock model. (2/2106)

The role of nitric oxide (NO) in lipopolysaccharide (LPS)-induced hepatic injury was studied in D-galactosamine (D-GalN)-sensitized mice. The inducible isoform of NO synthase (iNOS) was immunohistochemically detected on hepatocytes around blood vessels in livers of mice injected with D-GalN and LPS not on hepatocytes in mice injected with D-GalN or LPS alone, although mRNA for iNOS was found in those mice. Nitrotyrosine (NT) was also found in livers of mice injected with D-GalN and LPS. The localization of NT was consistent with that of iNOS, and the time courses of NT and iNOS expression were almost the same. Expression of iNOS and NT was detected exclusively in the hepatic lesions of mice injected with D-GalN and LPS. Anti-tumor necrosis factor alpha neutralizing antibody inhibited iNOS and NT expression and hepatic injury. The results suggested that NO from iNOS may play a role in LPS-induced hepatic injury on D-GalN-sensitized mice as an experimental endotoxic shock model.  (+info)

Neutralization of endotoxin in vitro and in vivo by a human lactoferrin-derived peptide. (3/2106)

Endotoxin (lipopolysaccharide [LPS]) is the major pathogenic factor of gram-negative septic shock, and endotoxin-induced death is associated with the host overproduction of tumor necrosis factor alpha (TNF-alpha). In the search for new antiendotoxin molecules, we studied the endotoxin-neutralizing capacity of a human lactoferrin-derived 33-mer synthetic peptide (GRRRRSVQWCAVSQPEATKCFQWQRNMRKVRGP; designated LF-33) representing the minimal sequence for lactoferrin binding to glycosaminoglycans. LF-33 inhibited the coagulation of the Limulus amebocyte lysate and the secretion of TNF-alpha by RAW 264.7 cells induced by lipid A and four different endotoxins with a potency comparable to that of polymyxin B. The first six residues at the N terminus of LF-33 were critical for its antiendotoxin activity. The endotoxin-neutralizing capacity of LF-33 and polymyxin B was attenuated by human serum. Coinjection of Escherichia coli LPS (125 ng) with LF-33 (2.5 microg) dramatically reduced the lethality of LPS in the galactosamine-sensitized mouse model. Significant protection of the mice against the lethal LPS challenge was also observed when LF-33 (100 microg) was given intravenously after intraperitoneal injection of LPS. Protection was correlated with a reduction in TNF-alpha levels in the mouse serum. These results demonstrate the endotoxin-neutralizing capability of LF-33 in vitro and in vivo and its potential use for the treatment of endotoxin-induced septic shock.  (+info)

In vivo isolated kidney perfusion with tumour necrosis factor alpha (TNF-alpha) in tumour-bearing rats. (4/2106)

Isolated perfusion of the extremities with high-dose tumour necrosis factor alpha (TNF-alpha) plus melphalan leads to dramatic tumour response in patients with irresectable soft tissue sarcoma or multiple melanoma in transit metastases. We developed in vivo isolated organ perfusion models to determine whether similar tumour responses in solid organ tumours can be obtained with this regimen. Here, we describe the technique of isolated kidney perfusion. We studied the feasibility of a perfusion with TNF-alpha and assessed its anti-tumour effects in tumour models differing in tumour vasculature. The maximal tolerated dose (MTD) proved to be only 1 microg TNF-alpha. Higher doses appeared to induce renal failure and a secondary cytokine release with fatal respiratory and septic shock-like symptoms. In vitro, the combination of TNF-alpha and melphalan did not result in a synergistic growth-inhibiting effect on CC 531 colon adenocarcinoma cells, whereas an additive effect was observed on osteosarcoma ROS-1 cells. In vivo isolated kidney perfusion, with TNF-alpha alone or in combination with melphalan, did not result in a significant anti-tumour response in either tumour model in a subrenal capsule assay. We conclude that, because of the susceptibility of the kidney to perfusion with TNF-alpha, the minimal threshold concentration of TNF-alpha to exert its anti-tumour effects was not reached. The applicability of TNF-alpha in isolated kidney perfusion for human tumours seems, therefore, questionable.  (+info)

Resistance of CD7-deficient mice to lipopolysaccharide-induced shock syndromes. (5/2106)

CD7 is an immunoglobulin superfamily molecule involved in T and natural killer (NK) cell activation and cytokine production. CD7-deficient animals develop normally but have antigen-specific defects in interferon (IFN)-gamma production and CD8(+) CTL generation. To determine the in vivo role of CD7 in systems dependent on IFN-gamma, the response of CD7-deficient mice to lipopolysaccharide (LPS)-induced shock syndromes was studied. In the high-dose LPS-induced shock model, 67% of CD7-deficient mice survived LPS injection, whereas 19% of control C57BL/6 mice survived LPS challenge (P < 0.001). CD7-deficient or C57BL/6 control mice were next injected with low-dose LPS (1 microgram plus 8 mg D-galactosamine [D-gal] per mouse) and monitored for survival. All CD7-deficient mice were alive 72 h after injection of LPS compared with 20% of C57BL/6 control mice (P < 0.001). After injection of LPS and D-gal, CD7-deficient mice had decreased serum IFN-gamma and tumor necrosis factor (TNF)-alpha levels compared with control C57BL/6 mice (P < 0.001). Steady-state mRNA levels for IFN-gamma and TNF-alpha in liver tissue were also significantly decreased in CD7-deficient mice compared with controls (P < 0.05). In contrast, CD7-deficient animals had normal liver interleukin (IL)-12, IL-18, and interleukin 1 converting enzyme (ICE) mRNA levels, and CD7-deficient splenocytes had normal IFN-gamma responses when stimulated with IL-12 and IL-18 in vitro. NK1.1(+)/ CD3(+) T cells are known to be key effector cells in the pathogenesis of toxic shock. Phenotypic analysis of liver mononuclear cells revealed that CD7-deficient mice had fewer numbers of liver NK1.1(+)/CD3(+) T cells (1.5 +/- 0.3 x 10(5)) versus C57BL/6 control mice (3.7 +/- 0.8 x 10(5); P < 0.05), whereas numbers of liver NK1.1(+)/CD3(-) NK cells were not different from controls. Thus, targeted disruption of CD7 leads to a selective deficiency of liver NK1.1(+)/ CD3(+) T cells, and is associated with resistance to LPS shock. These data suggest that CD7 is a key molecule in the inflammatory response leading to LPS-induced shock.  (+info)

The flesh-eating bacterium: what's next? (6/2106)

Since the 1980s, there has been a marked increase in the recognition and reporting of highly invasive group A streptococcal (GAS) infections associated with shock and organ failure, with or without necrotizing fasciitis. Such dramatic cases have been defined as streptococcal toxic shock syndrome (StrepTSS). Strains of GAS isolated from patients with invasive disease have been predominantly M types 1 and 3, which produce either pyrogenic exotoxin A or B or both. The clinical and demographic features of streptococcal bacteremia, myositis, and necrotizing fasciitis are presented and compared with those of StrepTSS. Current concepts in the pathogenesis of invasive streptococcal infection will be presented, with emphasis on the interaction between GAS virulence factors and host defense mechanisms. Finally, new concepts in the treatment of StrepTSS will be discussed.  (+info)

A novel receptor tyrosine kinase, Mer, inhibits TNF-alpha production and lipopolysaccharide-induced endotoxic shock. (7/2106)

The regulation of monocyte function and the inhibition of TNF-alpha production during bacterial sepsis are critical in attenuating adverse host responses to endotoxemia. To study the function of a novel receptor tyrosine kinase, mer, that is expressed in monocytes, we generated mice (merkd) that lack the signaling tyrosine kinase domain. Upon LPS challenge, merkd animals died of endotoxic shock (15/17, 88.2%), whereas control wild-type mice survived (1/15, 6.7% died). Susceptible merkd mice exhibited edema, leukocyte infiltration, and signs of endotoxic shock that correlated with higher levels of TNF-alpha found in the serum of merkd mice as compared with wild-type control animals. Death due to LPS-induced endotoxic shock in merkd mice was blocked by administration of anti-TNF-alpha Ab, suggesting that overproduction of this cytokine was principally responsible for the heightened suseptibility. The increase in TNF-alpha production appeared to be the result of a substantial increase in the LPS-dependent activation of NF-kappa B nuclear translocation resulting in greater TNF-alpha production by macrophages from merkd mice. Thus, Mer receptor tyrosine kinase signaling participates in a novel inhibitory pathway in macrophages important for regulating TNF-alpha secretion and attenuating endotoxic shock.  (+info)

Pyrrolidine dithiocarbamate prevents I-kappaB degradation and reduces microvascular injury induced by lipopolysaccharide in multiple organs. (8/2106)

Lipopolysaccharide (LPS) is a key mediator of multiple organ injury observed in septic shock. The mechanisms responsible for LPS-induced multiple organ injury remain obscure. In the present study, we tested the hypothesis that the LPS-induced injury occurs through activation of the transcription factor, nuclear factor-kappaB (NF-kappaB). We examined the effects of inhibiting NF-kappaB activation in vivo in the rat on LPS-induced: 1) gene and protein expression of the cytokine-inducible neutrophil chemoattractant (CINC) and intercellular adhesion molecule-1 (ICAM-1); b) neutrophil influx into lungs, heart, and liver; and c) increase in microvascular permeability induced by LPS in these organs. LPS (8 mg/kg, i.v.) challenge of rats activated NF-kappaB and induced CINC and ICAM-1 mRNA and protein expression. Pretreatment of rats with pyrrolidine dithiocarbamate (50, 100, and 200 mg/kg, i.p.), an inhibitor of NF-kappaB activation, prevented LPS-induced I-kappaBalpha degradation and the resultant NF-kappaB activation and inhibited, in a dose-related manner, the LPS-induced CINC and ICAM-1 mRNA and protein expression. Pyrrolidine dithiocarbamate also markedly reduced the LPS-induced tissue myeloperoxidase activity (an indicator of tissue neutrophil retention) and the LPS-induced increase in microvascular permeability in these organs. These results demonstrate that NF-kappaB activation is an important in vivo mechanism mediating LPS-induced CINC and ICAM-1 expression, as well as neutrophil recruitment, and the subsequent organ injury. Thus, inhibition of NF-kappaB activation may be an important strategy for the treatment of sepsis-induced multiple organ injury.  (+info)

Severe sepsis/septic shock is a serious condition associated with high mortality rate. The pathophysiology of the disease involves the complex interaction between hosts immunity and the microorganisms toxin. The release of immune complex and cascade of inflammatory cytokines are responsible for multiorgan dysfunction, especially the cardiovascular system. 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. Both anti-inflammation and supplementation of relatively adrenal insufficiency are the main hypothesis of the benefit of hydrocortisone. 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. Although there is controversy about timing and favorable patientscharacteristic, ...
Severe sepsis/septic shock are serious complications of infection with high morbidity and mortality. Recent information showed that early and aggressive resuscitation with goal directed therapy help improving survival and outcome especially the resuscitation within the first 6 hours. In surgical patients, either severe sepsis/septic shock bought them to the operating room or this sepsis might be found after surgery resulting in higher morbidity and mortality. Not only knowledge management, others possible risk factors should also be identified and corrected for outcome improving. This prospective observational study will be done in 800 adult surgical patients admitting to the general surgical intensive care unit. Incidence of severe sepsis/septic shock on admission along with risk factors associated with poor outcomes [organ failure (AKI, ALI, PMI, liver failure, stroke), prolonged ICU length of, stay, ICU death] will be recorded especially effect of amount and type of fluid replacement in the ...
The ASTONISH Phase IIB study aims at demonstrating safety and clinical efficacy of nangibotide in septic shock patients. It is a global, multicentric study conducted in 48 centers. Four hundred and fifty patients are planned to be enrolled in this study. The study compares the effect of nangibotide at two different doses versus standard of care. The futility analysis has been conducted on the first 225 patients enrolled. The primary endpoint for futility analysis was the delta SOFA score between the treatment groups and the standard of care/placebo group at day 5. A delta of 1 to 1.5 was observed in a previous Phase IIa trial in a subpopulation of septic shock patients with high concentration of soluble TREM-1, a mechanism-based biomarker. In addition, the ASTONISH study intends to validate a personalized medicine approach using soluble TREM-1 as potential companion diagnostic test to identify patients more likely to benefit from nangibotide treatment. The IDMCs decision marks a significant ...
Doctor answers on Symptoms, Diagnosis, Treatment, and More: Dr. Ihle on what is the difference between toxic shock syndrome and septic shock: Toxic shock syndrome is a specific cause of septic shock. Tss is caused by staph and sometimes strep bacteria which produce a toxin that can injure many organs. Septic shock is when an infection overwhelms the immune system and causes exaggerated inflammation usually due to bacterial infection, but sometimes viruses or fungal infections as well. If not corrected it has a high fatality rate. For topic: What Is The Difference Between Toxic Shock Syndrome And Septic Shock

Septic shock is the primary cause of death in intensive care units, with about 20% of patients dying in the first 3 days. To design future trials focused on early mortality, we require knowledge of early indicators that can detect patients at high risk of early death from refractory septic shock.The aim of this study was to assess whether the cumulative dose of vasopressors (CDV), calculated as the cumulative dose of epinephrine + norepinephrine, is a predictor of early death (within 72 hours) attributable to refractory septic shock (EDASS). This substudy of the EPISS trial was based on 370 patients admitted to a French ICU for septic shock between 2009 and 2011. The area under the receiving operating characteristic (ROC) curve was calculated for the CDV at 6, 12, 24, 36, and 48 hours after vasopressor initiation, and a strategy to predict the risk of EDASS was built based on selected times and thresholds.Among the 370 patients included, 51 (14%) died within the first 72 hours with 40 (11%) EDASS.

Septic shock is a serious medical condition that occurs when sepsis, which is organ injury or damage in response to infection, leads to dangerously low blood pressure and abnormalities in cellular metabolism. The primary infection is most commonly caused by bacteria, but also may be by fungi, viruses or parasites. It may be located in any part of the body, but most commonly in the lungs, brain, urinary tract, skin or abdominal organs. It can cause multiple organ dysfunction syndrome (formerly known as multiple organ failure) and death. Frequently, people with septic shock are cared for in intensive care units. It most commonly affects children, immunocompromised individuals, and the elderly, as their immune systems cannot deal with infection so effectively as those of healthy adults. The mortality rate from septic shock is approximately 25-50%. Septic shock is a subclass of distributive shock, a condition in which abnormal distribution of blood flow in the smallest blood vessels results in ...

It has been proposed that vasodilatory therapy may increase microcirculatory blood flow and improve tissue oxygenation in septic shock. The authors aimed to evaluate the effects of levosimendan in systemic and splanchnic hemodynamics in a porcine model of septic shock in a randomized animal controlled study. This study was performed in an animal research facility in a university hospital. Anesthetized pigs were monitored with a pulmonary artery catheter and an ultrasonic blood flow probe in the portal vein for measurement of systemic and portal blood flows and with a tonometer placed in the small intestine for measurement of the intramucosal-arterial PCO2 gap. Three groups of pigs were studied: nonseptic (n = 7), septic (n = 7), and septic treated with levosimendan (n = 7). Levosimendan was administered i.v. at t = -10 min (200 microg/kg in i.v. bolus followed by 200 microg/kg per h). Sepsis was induced at t = 0 min by the administration of live Escherichia coli. Vascular reactivity was tested ...

Background Septic shock is associated with high mortality. Aged and multimorbid patients are not always eligible for intensive care units. Norepinephrine is an accepted treatment for hypotension in septic shock. It is unknown whether norepinephrine has a place in treatment outside an intensive care unit and when given peripherally. Objectives To describe mortality, Acute Physiology And Chronic Health Evaluation (APACHE-II), time to mean arterial pressure |65 mmHg, and adverse events in patients with septic shock receiving norepinephrine peripherally in an intermediate care unit. Methods From a retrospective chart review of 91 patients with septic shock treated with norepinephrine for hypotension, ward mortality, 30-, 60- and 90-day mortality, standardized mortality ratio (SMR) and adverse events (necrosis and arrhythmia) were analysed. Administration route via peripheral venous catheter or central venous catheter was registered. Results Median age was 81 (43-96) years and median APACHE-II score
Perfusion-related variables exhibit markedly different normalization rates in septic shock survivors, most of them exhibiting a biphasic response with an initial rapid improvement, followed by a much slower trend thereafter. This fact should be taken into account to determine the most appropriate criteria to stop resuscitation opportunely and avoid the risk of over-resuscitation.. Central venous oxygen saturation, P(cv-a) CO2, and CRT values were already normal in the majority of patients at ICU admission after some previous volume loading, and it appears that these variables are particularly responsive to DO2 increasing maneuvers. In a previous study, ScvO2, increased from 49% to 77% in septic shock patients subjected to early aggressive DO2 optimization [3]. The sensitivity of ScvO2 to pre-ICU fluid loading probably explains the almost negligible incidence of low ScvO2 values in the ICU setting [25],[26]. CRT may also improve rapidly after fluid resuscitation, and we found that normality of ...
Antibiotics can lead to septic shock if used to treat - What types of antibiotics can cause septic shock? Did you mean bugs? Antibiotics dont cause septic shock, bacteria do. All kinds of bacteria can do this but most commonly gram-negatives from the urinary or gastrointestinal tract, gram-positives from skin etc infections and the various that cause pneumonia. Antibiotics are used to treat septic shock, together with all other supportive care.

We conducted genetic and functional analyses of isolates from a patient with group B streptococcal (GBS) necrotizing fasciitis and toxic shock syndrome. Tissue cultures simultaneously showed colonies with high hemolysis (HH) and low hemolysis (LH). Conversely, the HH and LH variants exhibited low capsule (LC) and high capsule (HC) expression, respectively. Molecular analysis demonstrated that the 2 GBS variants were of the same clonal origin. Genetic analysis found a 3-bp deletion in the covR gene of the HH/LC variant. Functionally, this isolate was associated with an increased growth rate in vitro and with higher interleukin-8 induction. However, in whole blood, opsonophagocytic and intracellular killing assays, the LH/HC phenotype demonstrated higher resistance to host phagocytic killing. In a murine model, LH/HC resulted in higher levels of bacteremia and increased host mortality rate. These findings demonstrate differences in GBS isolates of the same clonal origin but varying phenotypes.
DUSP3 is a small dual-specificity protein phosphatase with an unknown physiological function. We report that DUSP3 is strongly expressed in human and mouse monocytes and macrophages, and that its deficiency in mice promotes tolerance to LPS-induced endotoxin shock and to polymicrobial septic shock after cecal ligation and puncture. By using adoptive transfer experiments, we demonstrate that resistance to endotoxin is macrophage dependent and transferable, and that this protection is associated with a striking increase of M2-like macrophages in DUSP3−/− mice in both the LPS and cecal ligation and puncture models. We show that the altered response of DUSP3−/− mice to sepsis is reflected in decreased TNF production and impaired ERK1/2 activation. Our results demonstrate that DUSP3 plays a key and nonredundant role as a regulator of innate immune responses by mechanisms involving the control of ERK1/2 activation, TNF secretion, and macrophage polarization. ...
As regular PulmCCM readers know, the ProCESS, ARISE and ProMISe randomized trials showed no benefit of protocolized early goal-directed therapy as compared to usual conscientious care in the treatment of severe sepsis and septic shock.. In response to ProCESS and ARISE, the influential Surviving Sepsis Campaign now advises that measurement of central venous pressure (CVP) and central venous oxygenation (ScVO2) -- two core components of the so-called EGDT sepsis bundle -- are not necessary for all patients with septic shock.. As long as patients have received timely antibiotics and fluid resuscitation, the Campaign says, requiring measurement of CVP and ScvO2 in all patients ... is not supported by the available evidence.. They further reported that the Surviving Sepsis committee would immediately review the evidence to determine whether and when an update is needed to its practice-defining Surviving Sepsis Guidelines.. After the publication of ProMISe, it looks like that revision is coming ...
The initial rationale for EGDT was derived from a single-centre trial showing dramatic improvement in mortality rates (30.5% vs 46.5%) in patients with septic shock managed with protocolised care to meet the above physiological targets.16 However, recently published results from three large multicentre trials show no difference in outcomes between EGDT and usual care. The ProCESS trial in the USA of patients with septic shock showed no difference in 60-day mortality between groups managed to targets derived from invasive monitoring with EGDT, versus those managed to a protocol which did not require central monitoring, or by usual care.17 This study was carried out in academic centres and the overall mortality of 19% is far lower than classically observed for septic shock. All groups received on average more than 2 L of initial fluid resuscitation and 75% of patients had received antibiotics prior to randomisation. Similarly, the ARISE multicentre randomised trail compared EGDT to usual care in ...
In this multicenter study of hydrocortisone-treated patients with septic shock, intensive insulin therapy did not improve outcomes. An editorialist notes that (1) mean glucose levels in intensively treated patients fell short of the intended target, reaching only about 120 mg/dL, which was not markedly different from the mean glucose level (about 150 mg/dL) of the control group; and (2) the trial was underpowered to identify small differences in mortality. Thus, she calls for a much larger trial. My own sense, however, is that intensive glycemic control is not the magic bullet that will improve outcomes in septic shock patients and that research should be directed toward other pathophysiologic mechanisms ...

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is a subset of sepsis in which underlying circulatory and cellular/metabolic abnormalities are profound enough to substantially increase mortality. During the course of sepsis, circulating endotoxin levels can increase up to 1000-fold. Several studies have demonstrated that high endotoxin levels correlate with a higher mortality in sepsis and septic shock. The recent new sepsis definitions (published in JAMA, February 2016) describe septic shock as a pathologic condition with a mortality risk of more than 40%.. ...
This review supports current guidance that noradrenaline should be used as the first-choice vasopressor for adults with septic shock. Noradrenaline reduced mortality by 11% and major adverse events by two-thirds compared to dopamine. However, evidence of its effectiveness compared to the other vasopressors remains limited. Septic shock accounts for nearly one in ten admissions to intensive care units, where it is the most common cause of death. The survival rate for septic shock is only about 50%.
The CHESS study found that the monoclonal antibody HA-1A did not reduce mortality in patients with septic shock. In fact, there was a trend toward higher overall mortality with HA-1A compared with placebo. The studys large size and simple design support the validity of its findings. Evidence from both the HA-1A pivotal trial (1) and the CHESS trial suggests that HA-1A may harm some patients with septic shock. The finding that spontaneously reported, acute adverse events (2) were similar in the HA-1A and placebo groups is only marginally reassuring. The high background rate of adverse events in septic shock makes detection of drug-related events difficult; also, untoward effects of HA-1A may occur late. Therefore, mortality may be the best measure of harm. In the CHESS trial, excess mortality was found in patients without gram-negative sepsis who were treated with HA-1A (14-day mortality, 318 of 785 [41%] vs. 292 of 793 [37%]; P = 0.07), invoking an early stopping rule set up by the ...
Background: The incidence of sepsis continues to increase. Septic shock is a major cause of mortality in the United States and throughout the world. An adverse outcome of sepsis is cardiac dysfunction. Tachycardia increases the workload on the heart, which increases the metabolic demands required. It is imperative to identify new treatment options to help alleviate and manage the symptoms of sepsis. There are many potential benefits of beta-blockers for acutely ill patients. This includes a decreased oxygen demand related to a decreased heart rate (HR). This also results in reduced blood pressure and decreased workload of the heart. Will the administration of beta-blockers be effective at controlling heart rate and mitigating the harmful effects of beta-adrenergic receptor stimulation in patients with septic shock? Methods: An extensive search was conducted using Medline-OVID, CINAHL, and Web of Science using the keywords: beta-blocker and septic shock. The search was narrowed to only articles in
abstract = BACKGROUND: The indication, composition and timing of administration of non-resuscitation fluid in septic shock have so far received little attention and accordingly the potential to reduce this source of fluid is unknown. The objective of the study was to quantify and characterize non-resuscitation fluid administered to patients with septic shock.METHODS: This prospective observational study was performed in eight intensive care units in Sweden and Canada during 4 months in 2018. Adult patients with septic shock within 24 h of admission to the intensive care unit were eligible for inclusion. Non-resuscitation fluids were defined as fluids other than colloids, blood products and crystalloids at a rate ≥ 5 ml/kg/h. Indication, volume and type of fluid were recorded during the first 5 days after admission. A maximum of 30 patients could be included per centre. To estimate the potential to reduce administration of non-resuscitation fluid, a pragmatic {}restrictive{} protocol for ...
Cardiovascular dysfunction is common in severe sepsis or septic shock. Although functional alterations are often described, the elevated serum levels of cardiac proteins and autopsy findings of myocardial immune cell infiltration, edema, and damaged mitochondria suggest that structural changes to the heart during severe sepsis and septic shock may occur and may contribute to cardiac dysfunction. We explored the available literature on structural (versus functional) cardiac alterations during experimental and human endotoxemia and/or sepsis. Limited data suggest that the structural changes could be prevented, and myocardial function improved by (pre-)treatment with platelet-activating factor, cyclosporin A, glutamine, caffeine, simvastatin, or caspase inhibitors. ...
Out of 116 patients with sepsis, 54.3% were female. The median age was 73.5 years (IQR 63-82). The leading source of infection was the genitourinary tract (56.9%), followed by the lower respiratory tract (22.4%). A total of 35.3% of the patients experienced septic shock. Total ICU mortality for sepsis was 37.9%: 63.4% in patients with septic shock and 24.0% in patients without shock. Independent risk factors for ICU mortality were reduced mobility level (odds ratio [OR] 11.16, 95% confidence interval [CI] 2.45-50.91), failure to early recognize sepsis in the emergency department (OR 6.59, 95% CI 1.09-39.75), higher Sequential Organ Failure Assessment score at admission (OR 2.37, 95% CI 1.59-3.52), and inappropriate antimicrobial treatment (OR 9.99, 95% CI 2.57-38.87 ...
The SSC was implemented with a focus on improving outcomes in patients with sepsis and septic shock. The aim of the study was to analyze trends in percentage of survivors discharged to home versus subacute rehab or long-term acute care facilities, length of hospital stay and hospital charge per admission.. The 10-year retrospective analysis used the 2004 to 2014 Nationwide Inpatient Sample databases. Patients with a primary diagnosis of septic shock at discharge were included. The outcomes of interest were trends in overall in-hospital mortality, percentage of patients discharged to home, percentage of patients discharged to either subacute rehab or long-term acute care facilities, trends in length of stay and trends in hospital charge per admission, which was adjusted for inflation based on the consumer price index (CPI).. From 2004 to 2014, in-hospital mortality decreased from 51.7 percent to 39.3 percent. When comparing the two time periods, there were no significant differences in how often ...
The urine biomarkers tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been validated for predicting and stratifying AKI. In this study, we analyzed the utility of these biomarkers for distinguishing between transient and persistent AKI in the early phase of septic shock. We performed a prospective, multicenter study in 11 French ICUs. Patients presenting septic shock, with the development of AKI within the first 6 h, were included. Urine [TIMP-2]*[IGFBP7] was determined at inclusion (0 h), 6 h, 12 h, and 24 h. AKI was considered transient if it resolved within 3 days. Discriminative power was evaluated by receiver operating characteristic (ROC) curve analysis. We included 184 patients, within a median [IQR] time of 1.0 [0.0-3.0] h after norepinephrine (NE) initiation; 100 (54%) patients presented transient and 84 (46%) presented persistent AKI. Median [IQR] baseline urine [TIMP-2]*[IGFBP7] was higher in the persistent AKI group (2.21 [0.81
Septic myocardial dysfunction is a well recognised contributor to shock in sepsis but for many of us we assume this to be gross systolic impairment. Interestingly a recent study highlights that patients with severe sepsis and septic shock frequently have diastolic dysfunction1. They found that diastolic dysfunction was the strongest independent predictor of early mortality, even after adjusting for the APACHE-II score and other predictors of mortality.. In this study, 9.1% of severe sepsis/septic shock patients had isolated systolic dysfunction, 14.1% had combined systolic and diastolic dysfunction, and 38% had isolated diastolic dysfunction.. Importantly, the authors point out that although diastolic dysfunction is associated with age, hypertension, diabetes mellitus, and ischaemic heart disease, diastolic dysfunction is a stronger independent predictor of mortality than age and the other co-morbidities. However, a limitation of the study acknowledged by the authors is that it did not include ...

Sepsis is characterized by an early systemic inflammation in response to infection. In the brain, inflammation is associated with expression of pro-inflammatory cytokines (e.g. tumor necrosis factor-α, interleukin-1β and interleukin-6, among others) that may induce an overproduction of reactive oxygen and nitrogen species. The constitutive expression of cytokines in the brain is low, but may be induced by various stimuli, including lipopolysaccharide, which causes neuronal damage. Erythropoietin, among other effects, acts as a multifunctional neurotrophic factor implicated in neurogenesis, angiogenesis, vascular permeability, and immune regulation in the central nervous system. In an experimental model of endotoxic shock, we studied the neuroprotective capacity of erythropoietin in the rat hippocampus and compared with melatonin, a neurohormone with an important antioxidant and immunomodulatory effect. Methods: In 21-day-old male Wistar rats divided into eight groups, we administered by ...
The present study assessed the potential functions of interleukin (IL)-32α on inflammatory arthritis and endotoxin shock models using IL-32α transgenic (Tg) mice. The potential signaling pathway for the IL-32-tumor necrosis factor (TNF)α axis was analyzed in vitro. IL-32α Tg mice were generated under control of a ubiquitous promoter. Two disease models were used to examine in vivo effects of overexpressed IL-32α: Toll-like receptor (TLR) ligand-induced arthritis developed using a single injection of lipopolysaccharide (LPS) or zymosan into the knee joints; and endotoxin shock induced with intraperitoneal injection of LPS and D-galactosamine. TNFα antagonist etanercept was administered simultaneously with LPS in some mice. Using RAW264.7 cells, in vitro effects of exogenous IL-32α on TNFα, IL-6 or macrophage inflammatory protein 2 (MIP-2) production were assessed with or without inhibitors for nuclear factor kappa B (NFκB) or mitogen-activated protein kinase (MAPK). Single injection of LPS, but
Pearl: Corticosteroid administration should occur EARLY on in the patients resuscitation. Just as patients can develop acute kidney injury, encephalopathy, or heart failure as a result of poor perfusion, patients may also experience neuroendocrine dysfunction (hence the need for vasopressin, hydrocortisone, insulin replacement). Over the last 50 years many studies and meta-analyses have been conducted to try to answer the question of when to give steroids and who may benefit from them including Schumer, Bone, Cronin, Jurney, Annane, CORTICUS, and COIITSS. The largest RCT to date on the subject, called ADRENAL, is currently underway. Below is a summary of what we know so far.Corticosteroids should only be considered in patients with severe septic shock (systolic , 90 mmHg) who have failed adequate fluid resuscitation and initial vasopressor therapy.*. ...
BACKGROUND: The release of the Center for Medicare and Medicaid Services (CMS) latest quality measure, Severe Sepsis/Septic Shock Early Management Bundle (SEP-1), has intensified the long-standing debate over optimal care for severe sepsis and septic shock. Although the last decade of research has demonstrated the importance of comprehensive bundled care in conjunction with compliance mechanisms to reduce patient mortality, it is not clear that SEP-1 achieves this aim. The heterogeneous and often cryptic presentation of severe sepsis and septic shock, along with the multifaceted criteria for the definition of this clinical syndrome, pose a particular challenge for fitting requirements to this disease, and implementation could have unintended consequences ...

Staphylococcus aureus is a gram-positive bacterium that is an immobile coccus able to grow in both aerobic and anaerobic media and which forms grape like clusters. It is commonly found on the skin and nasal mucous membranes of humans and is capable of causing a wide range of disease from mild skin infections to life threatening pneumonia, septic shock and bacterial endocarditis.. Staphylococcus aureus is capable of generating a large array of exotoxins and the clinical syndrome of toxic shock (TSS) has been well documented since the late 1970s. Menstrual TSS has been on the decline over the past 20 years following an aggressive advertising campaign however the incidence of non-menstrual TSS has remained the same. Non-menstrual TSS has been described in respiratory tract infections, skin and soft tissue infections, bone infections and after numerous operations. The incidence remains around 1:100,000. The essential features of TSS are:. ...
Staphylococcal enterotoxin B (SEB) and related exotoxins produced by Staphylococcus aureus are potent activators of the immune system and cause toxic shock in humans. Currently there is no effective treatment except for the use of intravenous immunoglobulins administered shortly after SEB exposure. Intranasal SEB induces long-lasting lung injury which requires prolonged drug treatment. We investigated the effects of rapamycin, an immunosuppressive drug used to prevent graft rejection, by intranasal administration in a lethal mouse model of SEB-induced shock. The results show that intranasal rapamycin alone delivered as late as 17 h after SEB protected 100% of mice from lethal shock. Additionally, rapamycin diminished the weight loss and temperature fluctuations elicited by SEB. Intranasal rapamycin attenuated lung MCP-1, IL-2, IL-6, and IFNγ by 70%, 30%, 64%, and 68% respectively. Furthermore, short courses (three doses) of rapamycin were sufficient to block SEB-induced shock. Intranasal rapamycin
Streptococcus suis 2 (SS2) has evolved into a highly invasive pathogen responsible for two large-scale outbreaks of streptococcal toxic shock-like syndrome (STSLS) in China. Excessive inflammation stimulated by SS2 is considered a hallmark of STSLS, even it also plays important roles in other clinical symptoms of SS2-related disease, including meningitis, septicemia, and sudden death. However, the mechanism of SS2-caused excessive inflammation remains poorly understood. Here, a novel pro-inflammatory protein was identified (HP1330), which could induce robust expression of pro-inflammatory cytokines (TNF-α, MCP-1, and IL-1β) in RAW264.7 macrophages. To evaluate the role of HP1330 in SS2 virulence, an hp1330-deletion mutant (Δhp1330) was constructed. In vitro, hp1330 disruption led to a decreased pro-inflammatory ability of SS2 in RAW 264.7 macrophages. In vivo, Δhp1330 showed reduced lethality, pro-inflammatory activity, and bacterial loads in mice. To further elucidate the mechanism of HP1330

During the last half-century, numerous antiinflammatory agents were tested in dozens of clinical trials and have proven ineffective for treating septic shock. The observation in multiple studies that cell-free hemoglobin (CFH) levels are elevated during clinical sepsis and that the degree of increase correlates with higher mortality suggests an alternative approach. Human haptoglobin binds CFH with high affinity and, therefore, can potentially reduce iron availability and oxidative activity. CFH levels are elevated over approximately 24-48 hours in our antibiotic-treated canine model of S. aureus pneumonia that simulates the cardiovascular abnormalities of human septic shock. In this 96-hour model, resuscitative treatments, mechanical ventilation, sedation, and continuous care are translatable to management in human intensive care units. We found, in this S. aureus pneumonia model inducing septic shock, that commercial human haptoglobin concentrate infusions over 48-hours bind canine CFH, ...

The PPPS within a frequency band of 0.15 to 0.75 Hz was developed with an animal model using nine domesticated piglets simulating acute hemorrhagic shock and then validated in 17 nonsedated mechanically ventilated shock patients. Hemodynamic parameters were recorded before and after VE. In the animal model under anesthesia and pressure-controlled ventilation, the absolute and proportional change of cardiac index after VE (ΔCI and ΔCI%) positively correlated with the square root of PPPS (SQRT-PPPS, r = 0.34 and r = 0.72, ...
Adequate adrenocortical function is essential to survive critical illness. The goal of this study was to determine whether eosinophilia could serve as a useful and early marker of adrenal insufficiency in critically ill patients with severe septic shock. During a 1-year period, we prospectively studied 294 ICU patients.16 patients (5.4% of ICU admissions) with eosinophilia more than 3% of the white blood cell count and septic shock unresponsive to adequate fluid and vasopressor therapy, were included. A high dose (250 mcg i.v) corticotropin stimulation test was performed. Eosinophilia (>3%) was diagnosed in 16 patients with vasopressor-unresponsive septic shock. Eosinophilia was present 1.9±0.9d (range 8-96h) before the onset of septic shock. 11/16 patients failed to respond to corticotropin stimulation test above the critical level of 9 mcg/dL rise and 2/16 had baseline cortisol concentration ...
Main description: Severe sepsis and septic shock are the most serious compli- cations of bacterial infections. Both gram-positive and gram- negative bacteria can trigger these extreme inflammatory re- sponses and, by so doing, cause substantial morbidity and mortality. In the United States alone, over 400 000 patients suffer from septicaemia each year, and approximately 100 000 of these patients die despite optimal intensive care and modern antimicrobial therapy. These dramatic figures have prompted intensive research to define the bacterial and host factors involved in the septic response. Scientists from many disciplines, including chem- istry, physics, biology, medical microbiology, immunology, and pharmacology, have worked closely with clinicians to achieve rapid and profound progress. To translate this newly acquired knowledge into clinical practice, clinical trials have also been performed to evaluate numerous new therapeutic drugs. The disappointing results from these trials have ...
Originally, toxic shock syndrome was linked to the use of super-absorbent tampons. Research led to better tampons and better habits for using them, such as changing them often. The number of TSS cases dropped dramatically. Today about half of all TSS cases are related to menstruation.. The contraceptive sponge and the diaphragm, two types of birth control, have been linked to TSS. Toxic shock syndrome also can affect someone with any type of staph infection, including:. ...
Blood transfusions have been a central component of protocols for care of severe sepsis and septic shock, ever since the single-center 2001 Rivers trial included them in its interventions. Any benefit (or harm) caused by red cell transfusion independently was unknowable, and so the therapy became standard care as part of the so-called sepsis bundle. The Surviving Sepsis guidelines have generally advised transfusion to a hematocrit of 30% or hemoglobin of 10 g/dL during the first 6 hours of septic shock if hypoperfusion (low central venous oxygenation) is present despite fluids and vasopressors.. However, the inclusion of red cell transfusion in sepsis bundles has been frequently challenged, based on the weak observational evidence for its benefit, compared to robust evidence from randomized trials showing transfusion above a hemoglobin of 7 g/dL is unhelpful generally. This finding has been shown in the critically ill (the TRICC trial), after hip surgery (FOCUS trial) and in non-critically ill ...

INTRODUCTION: N-terminal pro brain natriuretic peptide (NT-proBNP) is a cardiac biomarker that has recently shown to be of diagnostic value in a diagnosis of decompensated heart failure, acute coronary syndromes and other conditions resulting in myocardial stretch. We sought to study whether sepsis-induced myocardial dilation would result in an elevation of NT-proBNP. METHOD: Serum NT-proBNP measurements were made in six consecutive patients with septic shock within 6 hours of admission to the intensive care unit. RESULTS: Markedly elevated levels of NT-proBNP were found in all six patients. CONCLUSIONS: NT-proBNP levels can be markedly elevated in critically ill patients presenting with septic shock. An elevated NT-proBNP level in a critically ill patient is not specific for decompensated heart failure ...

Clinical trial for Toxic Shock Syndrome , Infusion of Prostacyclin (Iloprost) vs Placebo for 72-hours in Patients With Septic Shock Suffering From Organ Failure
This case study reports on a 17-year-old male who reported to the pediatrician at a local rural hospital with complaints of pretibial pain in his right leg, after he accidentally cut his leg while in the fields a few days earlier. He was diagnosedfor having aphlegmon with an abscess followed by surgical debridement with wound nettoyage with no clinical signs of subcutaneous emphysema or necrotising fasciitis. Postoperatively the patients condition deteriorated and after admission to ICU he developed erythema, spreading from the right lower leg to the right upper leg, abdominal wall and the left leg, consistent with toxic shock syndrome and subsequent development of septic shock due to invasive S. aureus infection with respiratory failure, hemodynamic instability treated with vasopressors, hydrocortisone, antibiotic therapy. Due disease severity, CRRT was initiated with a CytoSorbadsorber with the only goal to remove cytokines (despite absence of acute kidney injury and no need for renal ...
BACKGROUND There have been conflicting reports on the efficacy of recombinant human activated protein C, or drotrecogin alfa (activated) (DrotAA), for the treatment of patients with septic shock.. METHODS In this randomized, double-blind, placebo-controlled, multicenter trial, we assigned 1697 patients with infection, systemic inflammation, and shock who were receiving fluids and vasopressors above a threshold dose for 4 hours to receive either DrotAA (at a dose of 24 mu g per kilogram of body weight per hour) or placebo for 96 hours. The primary outcome was death from any cause 28 days after randomization.. RESULTS At 28 days, 223 of 846 patients (26.4%) in the DrotAA group and 202 of 834 (24.2%) in the placebo group had died (relative risk in the DrotAA group, 1.09; 95% confidence interval [CI], 0.92 to 1.28; P = 0.31). At 90 days, 287 of 842 patients (34.1%) in the DrotAA group and 269 of 822 (32.7%) in the placebo group had died (relative risk, 1.04; 95% CI, 0.90 to 1.19; P = 0.56). Among ...
This campaign was initiated as a joint marketing effort by Eli Lilly and Edward Life Sciences to promote activated protein C (XIGRIS) and central venous catheters which measure the mixed venous oxygen saturation (yes, the same one Rivers held a patent for). The original backbone of the guidelines was the Rivers Trial.. The Surviving Sepsis Campaign has a track record of being sluggish to change based on the emergence of new data. For example, the Surviving Sepsis Campaign continued to recommend the use of central venous pressure and mixed venous oxygen saturation even after the PROCESS and ARISE trials demonstrated that these were non-beneficial. The campaign also has a history of making strong and arbitrary recommendations pulled out of thin air (e.g. 3-hour and 6-hour bundles of care involving fixed volumes of fluid resuscitation).. In 2018, the Surviving Sepsis Campaign issued an update recommending initiation of antibiotics and 30 cc/kg fluid bolus within sixty minutes of emergency ...
Doctors diagnosed the man with septic shock due to an infection with vibrio vulnificus, potentially deadly bacteria found in certain coastal waters that are present in higher concentrations in warmer months.. According to the Centers for Disease Control and Prevention, vibrio causes 80,000 illnesses and 100 deaths each year in the US. Most people become infected by eating raw seafood, particularly oysters, but exposing open wounds to brackish or salt water can also put a person at risk of infection.. People with compromised immune systems, especially those with chronic liver disease, are more likely to get vibriosis.. According to the case report, the patient had a history of cirrhosis of the liver and drank six 12-ounce beers daily.. Within 24 hours of admission, his condition declined with progressive septic shock and multi-organ system failure. Doctors put him on life support and treated him with aggressive antibiotics. Despite initial improvement, he continued to suffer complications related ...

BACKGROUND: The world population is mostly male at birth, although there is a shift in predominance over 55 years of age with more females than males. Male gender was recently hypothesized to be a risk factor for sepsis and septic shock; the reasons and the consequences of this odd discrepancy are yet a matter of debate. We investigated the percentage of males and females in a large number of trials performed on septic adult patients admitted to Intensive Care Units. METHODS: We analysed all the multicentre randomized controlled trials ever published in peer-reviewed Journals reporting a significant effect on mortality in intensive care unit septic adult patients; furthermore, we retrieved all the manuscripts dealing with sepsis or septic shock patients published in the last 3 years in the three medical Journals with the highest impact factor ...
Severe sepsis and septic shock are common conditions in various clinical settings. Since mortality rates can be as high as 60 percent, rapid recognition and goal-directed therapy leads to improved survival. While much information about the pathophysiology of the disease and ways to treat it are known, recent updated international Surviving Sepsis Campaign (SSC) guidelines do not provide a concrete recommendation whether crystalloids or colloids should be administered alone or in a combination to restore hemodynamic endpoints and reduce mortality in a more timely and effective manner. This review spotlights potential new ways to manage a septic patient with a fluid combination therapy.
Sepsis and septic shock are major healthcare problems, resulting in high morbidity and mortality. The Surviving Sepsis Campaign (SSC), which standardised the approach to sepsis, was recently updated. Strategies to decrease the systemic inflammatory response have been proposed to modulate organ dysfunctions. Endotoxin, derived from the membrane of Gram-negative bacteria, is considered a major factor in the pathogenesis of sepsis. Endotoxin adsorption, if effective, has the potential to reduce the biological cascade of Gram-negative sepsis. We present a case of a 64-year-old man with severe Gram-negative sepsis, following purulent peritonitis secondary to rectosigmoid adenocarcinoma. To reduce the amplitude of the general effects of endotoxins we used a novel device, the Alteco® LPS Adsorber (Alteco Medical AB, Lund, Sweden), for lipopolysaccharide (LPS) ...

Sepsis, as defined by the Surviving Sepsis Campaign (SSC) in 2012,[1] is the presence of a probable or documented infection together with systemic manifestations of an infection.. In 2004, the World Health Organization[2] listed three infective causes, namely lower respiratory tract infection, diarrhoeal disease and tuberculosis, on their top ten list of causes of death, which is similar to mortality reports documented in the 2013 Western Cape Mortality Profile.[3]This highlights the fact that sepsis and its sequelae - which were originally caused by an infection - are major contributors to the local and global burden of disease.. To date there are virtually no accurate data on the incidence and prevalence of or mortality rates for sepsis, severe sepsis and septic shock in developing countries. Mortality rates have been reported to be as high as 30% for sepsis, 40% for severe sepsis and 80% for septic shock[4-6] in developed countries. Septic shock is still the leading cause of death in ...

Sepsis is a heterogeneous class of syndromes caused by a systemic inflammatory response to infection. Septic shock, a severe form of sepsis, is associated with the development of progressive damage in multiple organs, and is a leading cause of patient mortality in intensive care units. Despite important advances in understanding its pathophysiology, therapy remains largely symptomatic and supportive. A decade ago, the overproduction of nitric oxide (NO) had been discovered as a potentially important event in this condition. As a result, great hopes arose that the pharmacological inhibition of NO synthesis could be developed into an efficient, mechanism-based therapeutic approach. Since then, an extraordinary effort by the scientific community has brought a deeper insight regarding the feasibility of this goal. Here we present in summary form the present state of knowledge of the biological chemistry and physiology of NO. We then proceed to a systematic review of experimental and clinic
Hypotension induced by sepsis was defined as a systolic pressure 40 mmHg, or a decrease of at least 2 standard deviations below the normal value for the age, in absence of other causes of hypotension.. This first attempt to give a definition has been universally acknowledged, and had the merit to create awareness in the clinical setting, and to promote standardization of management of patients with suspected or documented sepsis.. However, during the last years these definitions have been criticized, especially as regards to the non-specificity of SIRS definition. After an initial review of the definition in 2001 (with little impact on the scientific community), on the year 2016 the SCCM together with the European Society of Intensive Care Medicine (ESCIM) have released a consensus document which, after a 18-months work, lead to publication of the third edition of the definitions of sepsis and septic shock (Sepsis-3).. The new 2016 guidelines, published in JAMA, have the purpose of making the ...

The word tachycardia came to English from New Latin as a neoclassical compound built from the combining forms tachy- + -cardia, which are from the Greek ταχύς tachys, "quick, rapid" and καρδία, kardia, "heart". As a matter both of usage choices in the medical literature and of idiom in natural language, the words tachycardia and tachyarrhythmia are usually used interchangeably, or loosely enough that precise differentiation is not explicit. Some careful writers have tried to maintain a logical differentiation between them, which is reflected in major medical dictionaries[7][8][9] and major general dictionaries.[10][11][12] The distinction is that tachycardia be reserved for the rapid heart rate itself, regardless of cause, physiologic or pathologic (that is, from healthy response to exercise or from cardiac arrhythmia), and that tachyarrhythmia be reserved for the pathologic form (that is, an arrhythmia of the rapid rate type). This is why five of the previously referenced ...

A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls",[1] from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is apparent to a patient, reflecting the presence of an unusual state, or of a disease. A symptom can be subjective or objective. Tiredness is a subjective symptom whereas cough or fever are objective symptoms.[2] In contrast to a symptom, a sign is a clue to a disease elicited by an examiner or a doctor.[3] For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic. The term is sometimes also ...
