: Perioperative care of congenital protein C deficiency has not been well established. Here, we describe a patient with congenital protein C deficiency who underwent laparoscopic fundoplication and gastrostomy at 2 years of age. Preoperatively, we stopped warfarin, administered fresh frozen plasma, and activated protein C. These procedures were performed without bleeding or clotting events, and at 3 days after the procedures, we restarted warfarin. Several episodes of abdominal hemorrhage and purpura fulminans occurred 2-4 weeks postoperatively, and the events were managed conservatively...

: Hemophilia A carriers have an abnormal X chromosome with a molecular abnormality of FVIII gene. These carriers, long considered to be free of bleeding risk, could have the same symptoms as mild hemophiliacs. This study aim to assess bleeding risk of hemophilia A carriers monitored at the Clinical Hematology of Dakar. This is a prospective study of a period of 6 months including 22 hemophilia A carriers aged between 8 and 48 years. Hemophilia carriers were recruited using the genealogical tree of hemophiliacs followed in the service...

Mufuliat Adeola Adesanya, Anthony Maraveyas, Leigh Madden
: Calibrated automated thrombography (CAT) is emerging as a reliable tool for real-time estimation of thrombin generation potential. There is a clinical need for knowledge about the pathways underlying the thrombotic phenotype of different malignancies. Cells from solid (e.g. pancreatic cancer; n = 7) and malignant haematological cell lines (e.g. multiple myeloma; n = 5) were evaluated for thrombin generation, using CAT, with the addition of control plasma (NormTrol; Helena Biosciences, Gateshead, UK)) or plasma deficient in coagulation factors VII and XII...

Emma P DeLoughery, Thomas G DeLoughery
: When patients on anticoagulation present with intracranial bleeding, stopping the bleeding is paramount. Despite the availability of multiple options to reverse anticoagulation, no study has directly compared the effectiveness of the procoagulants recombinant activated factor VII (rFVIIa), the rFVIIa and 3-factor prothrombin complex concentrate (PCC) combination, and 4-factor PCC on improving patient outcomes compared with a control. This study examined the medical records of 197 warfarin patients with intracranial hemorrhage, an initial international normalized ratio (INR) greater than 1...

: Immune thrombocytopenic purpura (ITP) is an autoimmune disease in which increased platelet destruction and thrombocytopenia are diagnostic features. In fact, the exact pathogenesis of this disease is still unknown, but genetic changes can be a potential factor in the development of ITP. In this study, the relationship between polymorphisms with platelet destruction has been studied, which leads to decreased platelet count. Relevant literature was identified by a PubMed search (2000-2016) of English language papers using the terms 'ITP', 'polymorphism,' and 'immune system'...

: To evaluate the efficacy of international normalized ratio (INR) reversal using four-factor prothrombin complex concentrate (4F-PCC) in nonmedication-induced coagulopathy. We performed a single-site, retrospective cohort study of patients receiving off-label use of 4F-PCC. Cohorts included liver dysfunction if they had acute liver decompensation or cirrhosis without other causative factors of liver failure such as sepsis, coagulopathy of acute sepsis (CAS) if they had documentation of sepsis and no underlying liver disorder, known factor deficiencies, or medication-induced coagulopathy, or warfarin if they were taking warfarin...

Yanling Tao, Dongxiao Song, Fanyong Zhang, Saisai Ren, Hao Zhang, Lirong Sun
: Several reports have demonstrated T regulatory cells may play an important role in the pathophysiology of immune thrombocytopenia (ITP). As the immunomodulator, bone-marrow-derived mesenchymal stem cells (MSCs) (BM-MSCs) regulate T regulatory cells and show therapeutic effects on autoimmune diseases. However, it is not clear how BM-MSCs affect ITP. In this study, we explored the specific effects of BM-MSCs on ITP in mice. Using a murine model of ITP, mice were randomly divided into three groups: normal control group, ITP control group and ITP and BM-MSCs group...

: Congenital dysfibrinogenemia refers to the presence of a dysfunctional fibrinogen molecule, typically because of mutations in the fibrinogen gene. About 20% of fibrinogen gene mutations are responsible for thrombosis. Here, we described the case of a 17-year-old Japanese boy, who had a sudden stroke because of superior sagittal sinus thrombosis associated with dysfibrinogenemia. Genetic testing confirmed the presence of homozygous fibrinogen Naples (BβAla68Thr) mutation, which was previously reported as a causative mutation for thrombotic dysfibrinogenemia only in an Italian family...
