The diagnosis and management of bleeding disorders is made difficult by the complexity and variety of disorders, clinical symptoms and bleeding type and severity. von Willebrand disease (VWD) and platelet disorders are disorders of primary haemostasis and together represent the most common inherited bleeding disorders. In this article, we describe the diagnosis of VWD and platelet disorders and the treatment options for VWD.

Haemophilia patients with inhibitors require bypassing agents (BPA) like activated prothrombin complex concentrate (aPCC) and recombinant activated factor VII (rFVIIa) to control bleeds. Adjunct tranexamic acid (TXA) may improve haemostasis. The objective of this study was to investigate safety and haemostatic effect of TXA given in combination with BPA. ⋯ No clinical or laboratory signs of thromboembolic events, disseminated intravascular coagulation, or hypercoagulability were observed. Combination of aPCC or rFVIIa with TXA normalizes clot stability in haemophilia patients with inhibitor as compared to healthy controls. No clinical or laboratory adverse events were observed.

Rare bleeding disorders (RBDs) are inherited deficiencies of coagulation factors such as fibrinogen, factor (F) II, FV, FVII, combined FV+FVIII, FX, FXI and FXIII. These disorders usually have a low prevalence in the general population and constitute approximately 3-5% of all coagulation disorders. ⋯ The clinical picture of RBDs is highly variable and can vary markedly from mild to severe, making both diagnosis and optimal treatment quite challenging. This review focuses on: (i) the efforts to establish a bleeding assessment tool adequate to RBDs, (ii) the optimal management of patients affected with FXI deficiency and (iii) the correlation between clinical severity and laboratory diagnosis when determining the minimum coagulant activity required to prevent bleeding in each RBD.

This report summarizes recommendations relating to haemophilia therapy arising from discussions among experts from 36 European countries during the Kreuth III meeting in April 2013. To optimize the organization of haemophilia care nationally, it is recommended that a formal body be established in each country to include the relevant clinicians, national haemophilia patient organization, health ministry, paying authority and (if appropriate) regulatory authorities. The minimum factor VIII consumption level in a country should be 3 I. ⋯ Children with inhibitors who have failed, or who are not suitable for, immune tolerance therapy should be offered prophylaxis with bypassing agents. Single factor concentrates should be used as therapy wherever possible in patients with rare bleeding disorders. Orphan drug designation for a factor concentrate should not be used to hinder the development, licencing and marketing of other products for the same condition which have demonstrably different protein modification or enhancement.
