BACKGROUND: Venous thromboembolism is a known but rare complication associated with Mycobacterium tuberculosis infection. The reported incidence of venous thromboembolism is 1.5-3.4% of infected patients, and it occurs due to a hypercoagulable state induced by the associated inflammation. CASE REPORT: A young woman with pulmonary tuberculosis was found to have disseminated tuberculosis and a clinically unsuspected partial thrombus in the splenic vein on imaging...

Europe is an important market for illegal drugs, and nowadays a lot of new different psychoactive substances (NPS) are widespread. This work reports the development of a method to determine simultaneously different classes of NPS, as synthetic cannabinoids (SC) and their metabolites, cathinones and phenetylamines, directly on whole blood (WB) without anti-coagulants and using miniaturized solid phase extraction (μ-SPE). In order to demonstrate the feasibility of the method 16 different NPS belonging to the mentioned classes were selected for the analysis...

BACKGROUND: International normalized ratio (INR) and partial thromboplastin time (PTT) are used interchangeably to diagnose acute traumatic coagulopathy (ATC) but reflect disparate activation pathways. In this study we identified injury/patient characteristics and coagulation factors that drive contact pathway, tissue factor pathway (TF), and common pathway dysfunction by examining injured patients with discordant coagulopathies. We hypothesized that patients with INR/PTT discordance reflect differing phenotypes representing contact vs...

Cardiopathies and osteoporosis are inter-related due to pathogenetic, hormonal, genetic features as well as an increased risk of fragility. An important feature is attributed to the process of atherosclerosis, which is responsible for an osteopenia effect and degeneration of vascular walls. To date the study populations have been limited. To verify the incidence of cardio-vascular disease in a larger osteoporotic population, we designed a retrospective clinical study analyzing the “Hospital Discharge Data” (HDD) in Apulia between 2006 and 2010...

BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication of heparin administration. It can present a major clinical dilemma for physicians caring for patients requiring life-saving urgent or emergent cardiac surgery. Studies have been published examining the use of alternative anticoagulants for patients undergoing cardiopulmonary bypass (CPB), however, evidence does not clearly support any particular approach. Presently, there are no large-scale, prospective randomized studies examining the impact of alternative anticoagulants on clinical outcomes for HIT-positive patients requiring cardiac surgery...

BACKGROUND: Anticoagulation is the primary treatment for pulmonary embolism (PE). Inferior vena cava (IVC) filters are an adjunctive intervention to prevent recurrent pulmonary embolism. Long-term outcomes in elderly patients with contraindications to anticoagulation after IVC filter placement for prevention of recurrent pulmonary embolism have yet to be assessed. MATERIALS AND METHODS: Patients ≥60years of age, that had an IVC filter placed between January 1st, 2008 and February 2nd, 2013, with a primary diagnosis of pulmonary embolism, were included...

Ischemic stroke and cardiovascular disease can occur from blockage of blood vessels by fibrin clots formed naturally in the body. Therapeutic drugs of anticoagulant or thrombolytic agents have been studied; however, various problems have been reported such as side effects and low efficacy. Thus, development of new candidates that are more effective and safe is necessary. The objective of this study is to evaluate fibrinolytic activity, anti-coagulation, and characterization of serine protease purified from Lumbrineris nipponica, polychaeta, for new thrombolytic agents...

Activated factor-X (FXa) plays an important role not only in the coagulation cascade, but also in pro-inflammatory responses. However, few data exist regarding the anti-inflammatory effect of FXa inhibitors in clinical practice. The aim of this study was to evaluate the anti-inflammatory and anti-atherosclerotic effects of FXa inhibitors in Japanese patients with non-valvular atrial fibrillation (NVAF). Eighty-three patients with NVAF were treated with FXa inhibitors from March 2013 to March 2015 at our institution...

OBJECTIVE: To improve quality of care for patients presenting with chronic subdural haematoma (CSDH) by introducing a multi-disciplinary integrated care pathway. SUMMARY BACKGROUND: CSDH is a common neurological condition. Incidence rises with age and currently affects around 58/100 000 people over 70 years. Six-month mortality is high (26%), however integrated care pathways have been shown to improve patient outcomes in other surgical subspecialties. MATERIALS AND METHODS: A baseline retrospective audit completed in 2012 identified areas for improvement in patient management...

BACKGROUND: Temporal development of new-onset atrial fibrillation (NOAF) after aortic valve replacement is unclear, and opportunistic screening has limited diagnostic accuracy. This is the first study to investigate the incidence and temporal development of NOAF detected by implantable loop recorder (ILR) in patients with aortic stenosis, randomized to surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). METHOD: An ILR was implanted in a subgroup of patients without pre-procedural atrial fibrillation (AF), randomized to SAVR or TAVR in the NOTION trial...

Severe sepsis is a complex, multifactorial, and rapidly progressing disease characterized by excessive inflammation and coagulation following bacterial infection. To simultaneously suppress pro-inflammatory and pro-coagulant responses, we genetically engineered a novel fusion protein (MR1007) consisting of an anti-CD14 antibody and the modified second domain of bikunin, and evaluated the potential of MR1007 as an anti-sepsis agent. Suppressive effects of MR1007 on lipopolysaccharide (LPS)-induced inflammatory responses were assessed using peripheral blood mononuclear cells or endothelial cells...

Rivaroxaban, an inhibitor of Factor Xa, is a direct oral anti-coagulant that has been found to be non-inferior to warfarin in preventing cerebral ischemia in patients with non-valvular atrial fibrillation and in the subgroup of patients with a history of the previous stroke or transient ischemic attack. Vascular neurologists in daily clinical practice may encounter patients taking rivaroxaban or patients who may benefit from its use. In this paper, we review the current clinical indications, contraindications, and clinical management guidelines for rivaroxaban while providing a special focus on neurological aspects and expert opinions on rivaroxaban therapy management in various situations that a neurologist may encounter when treating patients with an ischemic stroke (including those requiring intravenous or intra-arterial reperfusion therapy) and patients with an intracerebral hemorrhage...

Early activation of coagulation is an important factor in the initiation of innate immunity, as characterized by thrombotic microangiopathy (TMA). In transplantation, systemic anticoagulation is difficult due to bleeding. A novel "cytotopic" agent, thrombalexin (TLN), combines a cell-membrane-bound (myristoyl tail) anti-thrombin (hirudin-like peptide [HLL]), which can be perfused directly to the donor organ or cells. Thromboelastography was used to measure time to clot formation (r-time) in both rhesus and human blood, comparing TLN versus HLL (without cytotopic tail) versus negative control...

We previously reported that insufficiency of antithrombin III (ATIII), the major anti-coagulation molecule in vivo, exacerbated renal ischemia-reperfusion injury in animal models and possibly humans. In the present study, we investigated the relationship between ATIII level and contrast induced nephropathy (CIN) in patients and examined therapeutic effect of ATIII on CIN in Sprague-Dawley rats. Patients with low ATIII activity presented a higher incidence of acute kidney injury (AKI) following coronary angiography...

BACKGROUND: Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis...

Patients with aneurysmal coronary artery fistulas are often a treatment challenge. We hereby, report a case of aneurysmal left main coronary artery to coronary sinus fistula repair, complicated by an early post-operative thrombosis of the left main coronary artery, necessitating an orthotropic heart transplant. Routine use of peri-procedural and long-term anti-coagulation is usually not a standard recommendation in these cases; however, early institution of the same may prevent flow stasis, thrombus formation and unfavourable outcomes pre- or post-operatively...
