[Anti-Xa activity in LMWH treatment: when to assess and what to do with the result].

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.

Major differences in clinical presentation, diagnosis and management of men and women with autosomal inherited bleeding disorders.

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)).

An evidence-based approach to pre-pregnancy counselling for patients with systemic lupus erythematosus.

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.
