The anti-factor Xa assay is designed to measure plasma low-molecular-weight heparin (LMWH) levels and to monitor heparin therapy. Notably, the results of anti-factor Xa testing cannot be used in the same way as the International Normalized Ratio (INR) is used to guide cumarin treatment: dose adjustments to remain in the therapeutic range have not been shown to be associated with better outcomes of care and lower rates of thrombotic and/or bleeding complications. The anti-factor Xa activity should therefore only be assessed in cases of considerable concern regarding an LWMH under- or overdosis.

Background: In recent years, more awareness is raised about sex-specific dilemmas in inherited bleeding disorders. However, no large studies have been performed to assess differences in diagnosis, bleeding phenotype and management of men and women with bleeding disorders. Therefore, we investigated sex differences in a large cohort of well-defined patients with autosomal inherited bleeding disorders (von Willebrand disease (VWD), rare bleeding disorders (RBDs) and congenital platelet defects (CPDs)).

Patients with SLE are often young females of childbearing age and a pregnancy wish in this patient group is common. However, SLE patients are at high risk for adverse pregnancy outcomes that require adequate guidance. It is widely acknowledged that pre-pregnancy counselling is the pivotal first step in the management of SLE patients with a wish to become pregnant.

Patients with von Willebrand disease (VWD), the most common inherited bleeding disorder, display large variation in bleeding tendency, which is not completely related to VWF levels. The cause of variability in clinical expression is largely unknown. The effect of plasma fibrinolytic capacity on bleeding tendency in VWD patients has not been investigated.

Introduction: Microparticles (MPs) carrying active tissue factor (TF) have been detected in the plasma of cancer patients in particular in those presenting with acute deep vein thrombosis (DVT) or pulmonary embolism (PE). Experimental studies in mice have revealed that circulating MPs carrying TF contribute to thrombus formation.

Aim: To study whether unselected patients with an acute confirmed PE have elevated TF activity in the MP fraction (MP-TF activity).

Summary Background: von Willebrand Disease (VWD) is the most frequent inherited bleeding disorder. It is unknown how this disorder affects quality of life.

Objectives: This nationwide multicenter cross-sectional study determined health-related quality of life (HR-QoL) in adult patients with moderate or severe VWD, and assessed whether bleeding severity and type of VWD are associated with HR-QoL.

High D-dimer levels are predictors of death in patients with pulmonary embolism (PE), as are more proximally located, larger emboli. The direct link between these three has not yet been described. A cohort of 674 consecutive patients with confirmed PE was studied.

Background And Objectives: Elevated levels of factor (F)VIII are associated with an increased risk of thrombosis. FVIII levels are determined mainly by von Willebrand factor (VWF). We have investigated the contribution of secretion and clearance rates to the elevated VWF antigen (VWF:Ag) and to the risk of thrombosis.

To determine the safety, efficacy and user-friendliness of two different postoperative autologous blood re-infusion systems, an open, randomized, controlled study was performed. Eligible consecutive primary and revision total hip and knee replacement patients were randomized for one of the two systems or for a control group in which shed blood was not re-infused. The nursing staff scored user-friendliness.

Henoch-Schönlein purpura is characterized by immunoglobulin A1 (IgA1) depositions in blood vessels of the skin or in glomeruli, resulting from altered hinge region O-glycosylation. Henoch-Schönlein purpura is seldom reported as a complication of IgA1 myeloma, even when the circulating IgA concentration is very high. We report two patients with IgA1 myeloma presenting with Henoch-Schönlein purpura.

Several case-control studies have shown that factor VIII levels > or = 150 IU/100 ml lead to a greatly increased risk of venous thrombosis. High levels of factor VIII are also associated with an increased risk of recurrences of thrombosis. The prevalence of high factor VIII levels is 25% in patients with a first episode of venous thrombosis and 11% among healthy controls.

Two women aged 84 and 86 years developed hypothermia after use of pipamperone. In one of the patients repeated administration of pipamperone again induced a decrease of body temperature. Although other clinical and environmental factors may have contributed to the development of hypothermia, a causal relationship between the use of pipamperone and the fall in body temperature appears likely considering the close temporal relationship.
