Severe malaria is common in tropical countries in Africa, Asia, Oceania and South and Central America. It may also occur in travelers returning from endemic areas. Plasmodium falciparum accounts for most cases, although P vivax is increasingly found to cause severe malaria in Asia. Cerebral malaria is common in children in Africa, manifests as coma and seizures, and has a high morbidity and mortality. In other regions, adults may also develop cerebral malaria but neurological sequelae in survivors are rare...

BACKGROUND: In the early stages of acute respiratory distress syndrome (ARDS), pro-inflammatory mediators inhibit natural anticoagulant factors and initiate an increase in procoagulant activity. Previous studies proved the beneficial effects of heparin in pulmonary coagulopathy, which derive from its anticoagulant and anti-inflammatory activities, although it is uncertain whether heparin works. Understanding the specific effect of unfractioned heparin on cell lung populations would be of interest to increase our knowledge about heparin pathways and to treat ARDS...

BACKGROUND: The fresh frozen plasma (FFP) transfusion threshold and timing for traumatic brain injury (TBI)-associated coagulopathy are controversial. Thus, a multicenter retrospective study was conducted to determine whether or not FFP transfusion is associated with poor outcomes after severe TBI. METHODS: Data from decompressive craniotomy after blunt force trauma that took place between December 2013 and June 2016 were collected in a multicenter chart. The primary outcomes were mortality and survival, as well as worse outcomes (defined as a Glasgow Outcome Scale [GOS] score ≤3) and better outcomes (GOS score ≥4)...

Acute respiratory distress syndrome (ARDS) caused by pneumonia in patients with hematologic malignancies can be life-threatening. Extracorporeal membrane oxygenation (ECMO) is the only temporary treatment for patients with ARDS who are refractory to conventional treatment. However, the immunosuppression and coagulopathies in hematological malignancies such as lymphoma and acute leukemia are relative contraindications for ECMO, due to high risks of infection and bleeding. Here, we report a 22-year-old man with acute myeloid leukemia (AML) who developed pneumonia and ARDS during induction chemotherapy; he was treated with ECMO...

Emergency care, including the resuscitation of patients involved in traumatic events, has evolved over the years. A prior practice of utilizing large volumes of crystalloids has been found to contribute to complications such as coagulopathy, fluid overload, and adult respiratory distress syndrome (ARDS). In contrast, permissive hypotension is a method of fluid restriction that allows for low blood pressure and mean arterial pressure during the resuscitation period. When permissive hypotension occurs and fluids are restricted in trauma patients, the incidence of ARDS can be reduced significantly with improvement in patient outcomes...

The utility of extracorporeal membrane oxygenation (ECMO) in patients with acute respiratory distress syndrome (ARDS) of noninfectious origin remains unclear. Data on patients with ARDS of noninfectious origin who underwent ECMO were reviewed retrospectively. We compared the pre-ECMO characteristics and hospital outcomes of patients with traumatic and nontraumatic ARDS. In total, 23 patients (trauma, n = 9; nontrauma, n = 14) were included in the study. The mean patient age was 42 years, there were three females, and the mean pre-ECMO Simplified Acute Physiologic Score (SAPS) II was 60...

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...

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...
