A number of studies have reported that acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are independent risk factors for organ dysfunction and mortality in patients with sepsis. Although ALI/ARDS might be an essential therapeutic target during the management of sepsis, severe sepsis should be treated effectively and as soon as identified. We have classified three phases, ranging from sepsis to organ dysfunction, characterizing the interaction between neutrophils and platelets. The first phase is neutrophil extracellular trap (NET) formation and intravasated platelet aggregation...

A snake breeder, 47-years-old man, was bitten by the saw-scaled viper (Echis carinatus sochureki). After admission to Toxinology Centre, within 1.5 h, laboratory evaluation showed clotting times prolonged to non-measurable values, afibrinogenaemia, significantly elevated D-dimers, haemolysis and myoglobin elevation. Currently unavailable antivenom was urgently imported and administered within 10 hours. In 24 hours, oligoanuric acute kidney injury (AKI) and mild acute respiratory distress syndrome (ARDS) developed...

Babesiosis, an infection caused by the protozoan Babesia microti and transmitted by the Ixodes scapularis tick, is commonly described in the literature with an approximate incidence of 1000 cases per year (Herwaldt et al., 2012). Infections in North America occur most frequently during the spring and summer months in the Northeastern and Midwestern United States. Babesia can cause a wide spectrum of clinical manifestations ranging from a self-limited febrile illness or mild anemia to severe illness causing acute respiratory distress syndrome (ARDS), disseminated intravascular coagulopathy (DIC) and multisystem organ failure...

RATIONALE: Pulmonary coagulopathy may play a pathogenetic role in acute respiratory distress syndrome (ARDS), by contributing to alveolocapillary inflammation and increased permeability. Recombinant human activated protein C (rh-APC) may inhibit this process and thereby improve patient outcome. METHODS: A prospective randomized, saline-controlled, single-blinded clinical trial was performed in the intensive care units of two university hospitals, and patients with ARDS were included within 24 h after meeting inclusion criteria...

BACKGROUND: Pulmonary coagulopathy has become an important therapeutic target in adult respiratory distress syndrome (ARDS). We hypothesized that combining intravenous recombinant human antithrombin (rhAT), nebulized heparin, and nebulized tissue plasminogen activator (TPA) more effectively improves pulmonary gas exchange compared with a single rhAT infusion, while maintaining the anti-inflammatory properties of rhAT in ARDS. Therefore, the present prospective, randomized experiment was conducted using an established ovine model...

Blood coagulation activation is frequently found in patients with malaria. Clinically apparent bleeding or disseminated intravascular coagulation (DIC) is associated with very severe disease and a high mortality. Protein C, protein S, and antithrombin levels were found to be low in P. falciparum, but were normal in P. vivax infection. Plasma levels of plasminogen activator inhibitor-1 were high in cases of P. falciparum infection whereas tissue plasminogen activator levels were low. Elevated plasma levels of von Willebrand factor (vWF) and vWF propeptide, thrombomodulin, endothelial microparticles have been reported in P...

The protein C system plays an active role in modulating severe systemic inflammatory processes such as sepsis, trauma, and acute respiratory distress syndrome (ARDS) via its anticoagulant and anti-inflammatory properties. Plasma levels of activated protein C (aPC) are lower than normal in acute inflammation in humans, except early after severe trauma when high plasma levels of aPC may play a mechanistic role in the development of posttraumatic coagulopathy. Thus, following positive results of preclinical studies, a clinical trial (PROWESS) with high continuous doses of recombinant human aPC given for 4 days demonstrated a survival benefit in patients with severe sepsis...

Amniotic fluid embolism (AFE) is an unpredictable and as-of-yet unpreventable complication of maternity. With its low incidence it is unlikely that any given practitioner will be confronted with a case of AFE. However, this rare occurrence carries a high probability of serious sequelae including cardiac arrest, ARDS, coagulopathy with massive hemorrhage, encephalopathy, seizures, and both maternal and infant mortality. In this review the current state of medical knowledge about AFE is outlined including its incidence, risk factors, diagnosis, pathophysiology, and clinical manifestations...

CONTEXT: Although extracorporeal membrane oxygenation (ECMO) was used in many patients following its introduction in 1972, most hospitals had abandoned this experimental treatment for adult patients. Recently, improvements in the ECMO circuitry rendered it more biocompatible. The surprisingly low mortality in patients with severe acute respiratory distress syndrome who were treated with ECMO in the influenza A/H1N1 pandemic of 2009 resurrected interest in ECMO in many intensive care units around the world...

OBJECTIVE: Acute respiratory distress syndrome (ARDS) frequently complicates critical illness. We hypothesized that an infusion of recombinant human activated protein C (rh-APC), a natural anticoagulant, would attenuate pulmonary coagulopathy and injury. METHODS: In this sub study of a multicenter open-label randomized controlled trial of patients with ARDS, we compared an intravenous (i.v.) infusion of rh-APC (24 mcg kg(-1)  h(-1) for 96 h) with placebo. Patients with sepsis or septic shock were excluded...

The coagulation cascade and inflammatory process are known to be associated with the pathophysiology of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We retrospectively investigated laboratory values indicating coagulopathy obtained within 24 hr from diagnosis of ALI/ARDS in 79 children who received mechanical ventilation between 2008 and 2009 and their final outcomes. Prothrombin time (PT) (P = 0.001) and activated partial thromboplastin time PTT (APTT) (P = 0.001) were more prolonged in non-survivors than survivors (mean; 1...

PURPOSE: Chemokines are a large superfamily of small proteins that function not only in leukocyte trafficking, but are also necessary for linkage between innate and adaptive immunity. Little is known about their role in septic shock. We hypothesized that serum levels of the most important chemokines are related to organ failure, disease severity and outcome. DESIGN: A prospective observational study was carried out. SETTING: Surgical-clinical Intensive Care Unit...

Enhanced intrapulmonary fibrin deposition as a result of abnormal broncho-alveolar fibrin turnover is a hallmark of acute respiratory distress syndrome (ARDS), pneumonia and ventilator-induced lung injury (VILI), and is important to the pathogenesis of these conditions. The mechanisms that contribute to alveolar coagulopathy are localized tissue factor-mediated thrombin generation, impaired activity of natural coagulation inhibitors and depression of bronchoalveolar urokinase plasminogen activator-mediated fibrinolysis, caused by the increase of plasminogen activator inhibitors...

Experimental pharmacotherapies for the acute respiratory distress syndrome (ARDS) have not met with success in the clinical realm. We hypothesized that chemically modified tetracycline 3 (CMT-3), an anti-inflammatory agent that blocks multiple proteases and cytokines, would prevent ARDS and injury in other organs in a clinically applicable, porcine model of inflammation-induced lung injury. Pigs (n = 15) were anesthetized and instrumented for monitoring. A "2-hit" injury was induced: (a) peritoneal sepsis-by placement of a fecal clot in the peritoneum, and (b) ischemia/reperfusion-by clamping the superior mesenteric artery for 30 min...

OBJECTIVE: To assess whether the presence of a pelvic fracture is associated with greater severity and worse prognosis in victims of blunt trauma. METHODS: A retrospective analysis of protocols and records of victims of blunt trauma admitted from June 2008 to March 2009 was separated into two groups: those with pelvic fracture (Group I) and those without it (Group II). Data were collected from pre-hospital admission rates of trauma, laboratory tests, diagnosed lesions, treatment and outcome...

Coagulopathy during massive haemorrhage increases morbidity and mortality rates. The modalities of treatment by transfusion of fresh frozen plasma (FFP) are a matter of debate. According to most clinical practice guidelines, FFP administration is driven by coagulation tests but, in cases of massive transfusion, patient management may be delayed whilst awaiting results and thawing FFP. Several retrospective cohort studies of military or civilian multiple trauma casualties requiring massive transfusion (>10 red blood cells (RBC) within 24h) have suggested that early use of FFP and high FFP:RBC ratios (approaching 1) might improve survival and lessen morbidity...
