Background and study aims:  Urgent endoscopy is often used to diagnose and sometimes treat acute upper gastrointestinal syndromes (hemorrhage, toxic ingestion, and occlusion). However, its suitability concerning the management of lower gastrointestinal conditions in emergency circumstances is controversial. Patients and methods:  We studied the role of emergency colonoscopy in diagnosis and treatment of all consecutive patients presenting with acute lower gastrointestinal symptoms referred to our hospital on an emergency basis...

High molecular weight kininogen (HK), together with Factor XI, Factor XII and prekallikrein, is part of the contact system, which has proinflammatory, prothrombotic and vasoactive properties. We hypothesized that HK plays a role in the host response during pneumonia derived sepsis. To this end mice were depleted of kininogen (KNG) to plasma HK levels of 28% of normal by repeated treatment with a specific antisense oligonucleotide (KNG ASO) for three weeks prior to infection with the common human sepsis pathogen Klebsiella pneumoniae via the airways...

BACKGROUND: During severe sepsis, levels and activity of all coagulation proteins are reduced. Heparanase is implicated in angiogenesis and tumor progression. We previously demonstrated that heparanase also affected the hemostatic system. It forms a complex and increases the activity of the blood coagulation initiator tissue factor. AIM: To evaluate heparanase levels and procoagulant activity as predictors of sepsis severity. MATERIALS AND METHODS: Twenty one patients with non-trauma, non-surgical sepsis admitted to the Intensive Care Unit and 35 controls were recruited...

BACKGROUND/AIM: Severe sepsis is associated with high morbidity and mortality rates. Inflammation and coagulation play pivotal roles in the pathogenesis of sepsis leading to multiple organ failure, especially in the liver. The aim of the present study was to assess the mechanism from sepsis to liver damage in a mouse model. MATERIALS AND METHODS: We created a sepsis model by injecting lipopolysaccharide (LPS) intraperitoneally in mice. At 0, 6, 12, and 24 h following intraperitoneal injection of LPS, mice were euthanised and analyzed...

BACKGROUND: No single anticoagulant has been proven effective for sepsis-associated disseminated intravascular coagulation (DIC). Thus, the concomitant use of antithrombin concentrate and recombinant thrombomodulin has been conceived. This observational study was conducted to investigate the efficacy and safety of this combination therapy. METHODS: A total of 510 septic DIC patients who received antithrombin substitution were retrospectively analyzed. Among them, 228 were treated with antithrombin and recombinant thrombomodulin (combination therapy) and the rest were treated with antithrombin alone (monotherapy)...

Sepsis caused by a Capnocytophaga canis infection has only been rarely reported. A 67-year-old female with a past medical history of splenectomy was admitted to our hospital with fever and general malaise. She had been bitten by a cat. She showed disseminated intravascular coagulation and multi-organ failure because of severe sepsis. On blood culture, characteristic gram-negative fusiform rods were detected; therefore, a Capnocytophaga species infection was suspected. A nucleotide sequence analysis revealed the species to be C...

Extracorporeal cardiopulmonary resuscitation (eCPR) has been well described as a rescue therapy in refractory cardiac arrest among patients with congenital heart disease. The purpose of this retrospective analysis of data from the Extracorporeal Life Support Organization was to evaluate outcomes of eCPR in patients with structurally normal hearts and to identify risk factors that may contribute to mortality. During the study period, 1,431 patients met inclusion criteria. Median age was 16 years. Overall survival to hospital discharge was 32%...

BACKGROUND Spontaneous retroperitoneal hemorrhage (SRH) is a rare and difficult-to-diagnose entity. It is not associated with trauma, pathology, or iatrogenic manipulations. Few cases have been reported, with the only precipitating factor recognized being bleeding diatheses such as anticoagulation states, inherited coagulopathies, and hemodialysis. However, none of these have been described in combination with septic shock, which itself is associated with platelet dysfunction, coagulation dysfunction, and vasculopathy...

A 51 year old man presented with severe sepsis, disseminated intravascular coagulation (DIC) and multiorgan dysfunction after a 24 hour history of diarrhoea and malaise. Despite fluid resuscitation and receiving a platelet transfusion, freshfrozen plasma and intravenous broad-spectrum antibiotics, he remained anuric with a worsening metabolic acidosis. He was transferred to critical care for organ support including renal replacement therapy. He subsequently developed purpura fulminans. Blood cultures were positive for Captocytophaga carnimorsis, a gram-negative canine zoonosis that is an underdiagnosed cause of severe sepsis, for which DIC at presentation is characteristic...

Sepsis brings great burden to the industry of health care and national economy, and antibiotics used in anti-infective treatment will cause the emergence of drug-resistant bacteria, adverse reactions, and reduce the efficacy and quality of life. However, with the deepening of the study of traditional Chinese medicine treatment of sepsis, in reducing the production of drug-resistant bacteria, changing the drug resistance of drug-resistant bacteria, preventing multiple infection, response to inflammatory response and immune damage, treatment of gastrointestinal dysfunction and coagulation disorders, TCM is gradually exerting its advantages...

BACKGROUND: Thrombocytopenia is a common feature of sepsis and may involve various mechanisms often related to the inflammatory response. This study aimed at evaluating factors associated with thrombocytopenia during human septic shock. In particular, we used a multiplex analysis to assess the role of endogenous sepsis mediators. METHODS: Prospective, observational study. Thrombocytopenia was defined as an absolute platelet count <100 G/L or a 50% relative decrease in platelet count during the first week of septic shock...

Sepsis concurrently activate both coagulation and complement systems. While complement activation by bacteria is well-documented, work in mice and in vitro suggests that coagulation proteases can directly cleave complement proteins. We aimed to determine if generation of coagulation proteases in vivo can activate the complement cascade in two highly coagulopathic models. We compared temporal changes in activation biomarkers of coagulation (thrombin-antithrombin, TAT), fibrinolysis (plasmin-antiplasmin, PAP) and complement (C3b, C5a, C5b-9) in baboons infused with factor Xa and phospholipids (FXa/PCPS) vs...

PURPOSE: The study purpose was to define changes in coagulation across the sepsis spectrum using rotational thromboelastometry (ROTEM). METHODS: Sepsis patients were recruited on admission to the Emergency Department and Intensive Care Units of a large teaching hospital in Wales. ROTEM markers of clot development and fibrinolysis were determined, as well as standard coagulation markers. A healthy control group matched for age and gender was also recruited (n=44)...

BACKGROUND: Disruption of the endothelial glycocalyx contributes to acute lung injury in experimental sepsis but has not been well studied in humans. To study glycocalyx degradation in sepsis-induced ARDS, we measured plasma levels of syndecan-1, a marker for glycocalyx degradation. METHODS: The present study is a retrospective observational study of 262 ventilated medical ICU patients at risk of ARDS due to severe sepsis and APACHE II ≥ 25. Plasma syndecan-1 was measured at study enrollment...

Sepsis is a lethal syndrome with a high incidence and a weighty economy burden. The pathophysiology of sepsis includes inflammation, immune dysfunction, and dysfunction of coagulation, while sepsis-induced cardiomyopathy (SIC), defined as a global but reversible dysfunction of both sides of the heart induced by sepsis, plays a significant role in all of the aspects above in the pathogenesis of sepsis. The complex pathogenesis of SIC involves a combination of dysregulation of inflammatory mediators, mitochondrial dysfunction, oxidative stress, disorder of calcium regulation, autonomic nervous system dysregulation, and endothelial dysfunction...

OBJECTIVE: Recent clinical studies have shown that anticoagulant therapy might be effective only in specific at-risk subgroups of patients with sepsis and coagulation dysfunction. The definition of sepsis was recently modified, and as such, old scoring systems may no longer be appropriate for the diagnosis of sepsis-associated coagulopathy. The aim of this study was to evaluate prognostic factors in patients diagnosed with sepsis and coagulopathy according to the new sepsis definition and assess their accuracy in comparison with existing models...

Guidelines for infusion fluid therapy rarely take into account that adverse effects occur in a dose-dependent fashion. Adverse effects of crystalloid fluids are related to their preferential distribution to the interstitium of the subcutis, the gut, and the lungs. The gastrointestinal recovery time is prolonged by 2 days when more than 2 litres is administered. Infusion of 6-7 litres during open abdominal surgery results in poor wound healing, pulmonary oedema, and pneumonia. There is also a risk of fatal postoperative pulmonary oedema that might develop several days after the surgery...

Prolongation of prothrombin time (PT) is often encountered in patients with sepsis. On the other hand, thromboelastometry as a global coagulation test might yield normal results. The aim of our study was to evaluate whether prolonged PT in the presence of normal thromboelastometry parameters is associated with severe bleeding in patients with sepsis undergoing invasive procedures. In patients with sepsis undergoing low-risk bleeding invasive procedures (central venous catheter placement, dialysis catheter insertion, drain insertion, and so on) or high-risk bleeding invasive procedures (surgical tracheostomy, surgical laparotomy, thoracotomy, and so on), coagulation was assessed by thromboelastometry using EXTEM test (test for evaluation of the extrinsic pathway of coagulation, contains activator of extrinsic pathway) and with PT...
