Background Andexanet alfa (andexanet) is a recombinant modified human factor Xa decoy protein that has been shown to reverse the inhibition of factor Xa in healthy volunteers. Methods In this multicenter, prospective, open-label, single-group study, we evaluated 67 patients who had acute major bleeding within 18 hours after the administration of a factor Xa inhibitor. The patients all received a bolus of andexanet followed by a 2-hour infusion of the drug. Patients were evaluated for changes in measures of anti-factor Xa activity and were assessed for clinical hemostatic efficacy during a 12-hour period...

Direct oral anticoagulants (DOACs) offer noninferior efficacy and improved safety compared to vitamin K antagonists (VKAs) for the prevention and treatment of venous thromboembolism and for the prevention of stroke and systemic embolism in nonvalvular atrial fibrillation. Unlike VKAs, DOACs do not require routine laboratory monitoring of anticoagulant effect and dose adjustment. In certain situations, however, laboratory assessment of anticoagulant effect may be desirable. Here we review the utility of currently available assays for assessment of DOAC effect and recommend an optimal assessment strategy for each drug, including calibrated dilute thrombin time or ecarin-based assays for dabigatran and calibrated anti-Xa activity assays for the factor Xa inhibitors...

In our daily anaesthetic practice, we are confronted with an increasing number of patients treated with either antiplatelet or anticoagulant agents. During the last decade, changes have occurred that make the handling of antithrombotic medication a challenging part of anaesthetic perioperative management. In this review, the authors discuss the most important antiplatelet and anticoagulant drugs, the perioperative management, the handling of bleeding complications, and the interpretation of some laboratory analyses related to these agents...

BACKGROUND: Multiple myeloma is a malignant disease of plasma cells with a worldwide incidence of 6-7 cases per 100 000 persons per year. It is among the 20 most common types of cancer in Germany. METHODS: This review is based on pertinent publications up to December 2015 that were retrieved by a selective search of PubMed employing the terms "multiple myeloma" AND "therapy" OR "diagnostic." Systematic reviews, meta-analyses, randomized controlled trials, and treatment recommendations from Germany and abroad were considered...

Heparin-induced thrombocytopenia (HIT) is a relatively common prothrombotic adverse drug reaction of unusual pathogenesis that features platelet-activating immunoglobulin G antibodies. The HIT immune response is remarkably transient, with heparin-dependent antibodies no longer detectable 40 to 100 days (median) after an episode of HIT, depending on the assay performed. Moreover, the minimum interval from an immunizing heparin exposure to the development of HIT is 5 days irrespective of the patient's previous heparin exposure status or history of HIT...

BACKGROUND: In spite of the clear evidence of benefit of aspirin in the secondary prevention of cerebrovascular and cardiovascular thrombotic events, its use in patients at high risk due to a previous event remains suboptimal. A possible explanation for this underuse is concern regarding the relative benefit in relation to the potential risk for serious gastrointestinal events. OBJECTIVE: To compare the benefit and gastrointestinal risk of aspirin use for the secondary prevention of thromboembolic events...

BACKGROUND: Dual antiplatelet therapy (DAT) with clopidogrel plus aspirin is a well-established antithrombotic strategy, with hemorrhage being the chief adverse event (AE) of concern. Outside of clinical trials, few published data describe the magnitude and nature of hemorrhage-related AEs from DAT. METHODS: To estimate the numbers and rates of emergency department (ED) visits for hemorrhage-related AEs (hemorrhage or evaluation for potential hemorrhage) from DAT in the United States and put them in the context of those from warfarin, we analyzed AEs from the National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance project, 2006-2008, and outpatient prescribing from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey, 2006-2007...

OBJECTIVE: To determine the real world risk of gastrointestinal bleeding associated with the use of the novel oral anticoagulants dabigatran and rivaroxaban compared with warfarin. DESIGN: Retrospective, propensity matched cohort study. SETTING: Optum Labs Data Warehouse, a large database including administrative claims data on privately insured and Medicare Advantage enrollees. PARTICIPANTS: New users of dabigatran, rivaroxaban, and warfarin from 1 November 2010 to 30 September 2013...

The risk of recurrent venous thromboembolism (VTE) must be weighed against the risk of bleeding in deciding to keep patients on extended anticoagulation with vitamin K antagonists (VKAs). Most of the studies of risk of bleeding on VKAs are randomized controlled trials of highly selected patients followed for less than 1 year. We sought to determine the rate of bleeding in 'real world' patients on long-term anticoagulation with VKAs for VTE. We conducted a retrospective cohort study of patients monitored at our anticoagulation clinic who were treated with prolonged anticoagulation (>1 year) for secondary VTE prevention to assess the incidence of significant bleeding in this population...

BACKGROUND: Anemia is a major cause of morbidity in patients with cancer resulting in poor physical performance, prognosis and therapy outcome. The aim of this study is to assess the efficacy of intravenous (iv) iron administration for the correction of anemia, for the prevention of exacerbation of anemia, for decreasing blood transfusion rates, and for the survival of cancer patients. METHODS: Patients with different solid tumor diagnosis who received iv iron during their cancer treatment were evaluated retrospectively...

BACKGROUND: Antimicrobial-induced thrombocytopenia is frequently described in the literature among critically ill patients. Several antimicrobials have been implicated, although experimental evidence to demonstrate causality is limited. We report, using a randomized trial, the potential of antimicrobials to induce thrombocytopenia. METHODS: Randomized trial allocated patients to antimicrobial treatment according to standard- of-care (SOC group) or drug-escalation in case of procalcitonin increases (high-exposure group)...

Hemoglobin thresholds and triggers for blood transfusions have changed over the years moving from a higher to a lower level. This review article summarizes the current evidence of transfusion thresholds in the hospitalized as well as in the outpatient setting and particularly in myelodysplasia. Fatigue is the main reported symptom in this group of patients and current clinical trials are looking for a more liberal approach of red cell transfusion and the effect on quality of life as opposed to the restrictive strategy used in the critical care setting...

BACKGROUND: The monoclonal anti-CD20 antibody rituximab, combined with chemotherapeutic agents, has been shown to prolong overall survival in physically fit patients with previously untreated chronic lymphocytic leukemia (CLL) but not in those with coexisting conditions. We investigated the benefit of the type 2, glycoengineered antibody obinutuzumab (also known as GA101) as compared with that of rituximab, each combined with chlorambucil, in patients with previously untreated CLL and coexisting conditions...

A better understanding of the biology of chronic lymphocytic leukemia (CLL) has led to significant advances in therapeutic strategies for patients with CLL. Chemoimmunotherapy (CIT) has been the standard first-line therapy for CLL. Age and comorbidities can help decide which patients may benefit from a CIT approach. FCR (fludarabine, cyclophosphamide, and rituximab) is the current standard treatment option for younger patients with CLL. For older patients and for patients with renal dysfunction, bendamustine and rituximab may be a better option...

BACKGROUND: Iron-deficiency anaemia is highly prevalent among non-pregnant women of reproductive age (menstruating women) worldwide, although the prevalence is highest in lower-income settings. Iron-deficiency anaemia has been associated with a range of adverse health outcomes, which restitution of iron stores using iron supplementation has been considered likely to resolve. Although there have been many trials reporting effects of iron in non-pregnant women, these trials have never been synthesised in a systematic review...

Most knowledge of hemophagocytic syndromes (HPSs) including hemophagocytic lymphohistiocytosis (HLH) is derived from pediatric studies; literature on adult HPS/HLH predominantly consists of small retrospective studies with clinical and methodological heterogeneity. The aims of this systematic scoping review were to provide an overview of existing literature on adult HPS/HLH, describe current practices in diagnosis and treatment, and propose priorities for future research. Articles from Ovid Medline, Embase and Pubmed (1975-2015) describing 10 or more unique adults (age>15years) with HPS/HLH were included...

BACKGROUND: Direct oral anticoagulants (DOAs) have been shown to be as effective and at least as safe as conventional anticoagulation for the prevention of recurrences in patients with VTE. Whether this is the case in patients with cancer-associated VTE remains undefined. METHODS: We performed a meta-analysis of randomized controlled trials with the aim of assessing the efficacy and safety of DOAs in patients with VTE and cancer. MEDLINE, EMBASE, and CENTRAL were searched up to December 2013 with no language restriction...
