A 67-year-old man presented with a 3-day history of abdominal pain, fever, and significant weight loss over 2 months. Physical examination revealed left upper quadrant tenderness, hepatomegaly, splenomegaly, and bilateral pitting edema but peripheral lymphadenopathy was absent. Laboratory tests showed anemia, thrombocytopenia, elevated prothrombin time (PT), partial thromboplastin time (PTT), and increased lactate dehydrogenase (LDH). PTT was corrected completely in mixing study. Further workup for the cause of coagulopathy revealed decreased levels of all clotting factors except factor VIII and increase fibrinogen levels, which ruled out disseminated intravascular coagulation (DIC)...

OBJECTIVE: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) has gained widespread use through a solid reputation of safety and effectiveness. However, some issues, such as endoleaks and sac growth over time, still arise as important concerns. Antiplatelet therapy, mandatory as secondary prevention of cardiovascular disease, may play a role in both phenomena by interfering with blood clotting properties and the inflammatory process associated with AAA. We analyzed whether different antiplatelet therapies were independent risk factors for type II endoleak (T2E) persistence and midterm sac growth after EVAR...

Bleeding associated with hemorrhagic shock is often seen in emergency medical services or in the intensive care unit. Identifying the origin of the bleeding and additional disorders helps to determine the degree of the hemorrhagic shock. In order to be effective, the initial therapy until blood products are available needs to be differentiated to be effective in terms of hemodynamic stabilization and coagulation. Crystalloidal and colloidal solutions should be used carefully since those solutions bear a risk within themselves...

In view of the escalating need for autologous cell-based therapy for treatment of liver diseases, a novel candidate has been explored in the present study. The monocytes isolated from hepatitis B surface antigen (HBsAg) nucleic acid test (NAT)-positive (HNP) blood were differentiated to hepatocyte-like cells (NeoHep) in vitro by a two-step culture procedure. The excess neutrophils present in HNP blood were removed before setting up the culture. In the first step of culture, apoptotic cells were depleted and genes involved in hypoxia were induced, which was followed by the upregulation of genes involved in the c-MET signaling pathway in the second step...

BACKGROUND: Fibrin plays a crucial role in haemostasis and wound healing by forming strain-stiffening fibrous networks that reinforce blood clots. The molecular origin of fibrin's strain-stiffening behavior remains poorly understood, primarily because plasma fibrinogen is a complex mixture of heterogeneous molecular variants and is often contaminated by plasma factors that affect clot properties. OBJECTIVES AND METHODS: To facilitate mechanistic dissection of fibrin nonlinear elasticity, we produced a homogeneous recombinant fibrinogen corresponding to the main variant in human plasma, termed rFib610...

Fibrin metabolism is influenced by many factors. The velocity of fibrin formation, genetic polymorphisms, fibrinolytic features and the structure of the fibrin clot are determinants of fibrin turnover. Oral contraceptives (OCs) have significant impact on the haemostatic system, by increasing the concentration of coagulation factors, plasminogen and tissue plasminogen activator activity, and decreasing the concentration of haemostatic inhibitors. The present study addresses the influence of OCs on fibrin structure and fibrin metabolism...

Perivascular adipose tissue (PVAT) releases multiple factors and adipokines with paracrine effects on both vascular structure and function. This influence is variable depending on regional differences in PVAT among blood vessels and with changes in adiposity. Considerable evidence demonstrates the association between coronary PVAT and the development and progression of coronary artery disease, associated with inflammation, oxidative stress, angiogenesis, vascular remodeling and blood clotting. However, PVAT also has a protective role on vascular grafts, especially the no-touch saphenous vein, in patients undergoing coronary artery bypass...

Platelets are anuclear cells that are essential for blood clotting. They are produced by large polyploid precursor cells called megakaryocytes. Previous genome-wide association studies in nearly 70,000 individuals indicated that single nucleotide variants (SNVs) in the gene encoding the actin cytoskeletal regulator tropomyosin 4 (TPM4) exert an effect on the count and volume of platelets. Platelet number and volume are independent risk factors for heart attack and stroke. Here, we have identified 2 unrelated families in the BRIDGE Bleeding and Platelet Disorders (BPD) collection who carry a TPM4 variant that causes truncation of the TPM4 protein and segregates with macrothrombocytopenia, a disorder characterized by low platelet count...

BACKGROUND: Production of recombinant factor VIII (FVIII) is challenging due to its low expression. It was previously shown that codon-optimization of a B domain-deleted FVIII (BDD-FVIII) cDNA resulted in increased protein expression. However, it is well-recognized that synonymous mutations may affect the protein structure and function. OBJECTIVES: To compare biochemical properties of a BDD-FVIII expressed from codon-optimized (CO) and the wild-type (WT) cDNAs. METHODS: Each variant of the BDD-FVIII was expressed in several independent CHO cell lines, generated using a lentiviral platform...

Cryoglobulins are immunoglobulins that precipitate in serum at temperatures below 37°C and resolubilize upon warming. The clinical syndrome of cryoglobulinemia usually includes purpura, weakness, and arthralgia, but the underlying disease may also contribute other symptoms. Blood samples for cryoglobulin are collected, transported, clotted and spun at 37°C, before the precipitate is allowed to form when serum is stored at 4°C in a Wintrobe tube for at least seven days. The most critical and confounding factor affecting the cryoglobulin test is when the preanalytical phase is not fully completed at 37°C...
