Acquired Haemophilia A in four north European countries: survey of 181 patients.

Acquired haemophilia A (AHA) is a rare bleeding disorder caused by acquired antibodies against coagulation factor VIII. In the Nordic countries, treatment and outcomes have not been studied in recent times. To collect retrospective data on patients diagnosed with AHA in the Nordic countries between 2006 and 2018 and compare demographic data and clinical outcomes with previously published reports, data were collected by six haemophilia centres: three Swedish, one Finnish, one Danish and one Estonian.

Platelet function testing: Current practice among clinical centres in Northern Europe.

Introduction: Platelet function tests are used to screen and diagnose patients with possible inherited platelet function defects (IPFD). Some acquired platelet dysfunction may be caused by certain drugs or comorbidities, which need to be excluded before testing.

Aims: To identify current practice among centres performing platelet function tests in Northern Europe.

Von Willebrand Factor Multimeric Assay in Acquired von Willebrand Disease Diagnosis: A Report of Experience from North Estonia Medical Centre.

Acquired von Willebrand syndrome (AVWS) is a rare and frequently underdiagnosed bleeding disorder with an unknown prevalence. The diagnosis of AVWS is made based on laboratory investigations and the presence of clinical symptoms. Evaluation and management of affected patients are complex due to the need for multiple laboratory assays.

Methods for individualising factor VIII dosing in prophylaxis.

Haemophilia A is a sex-linked disorder characterised chiefly by recurrent, spontaneous joint and muscle bleedings resulting from deficiency of factor VIII (FVIII). Recurrent joint bleeds result in haemophilic arthropathy. Unless treated with factor replacement therapy, many patients with severe haemophilia become disabled.
