Intracranial haemorrhage in children and adolescents with severe haemophilia A or B - the impact of prophylactic treatment.

The discussion of prophylactic therapy in haemophilia is largely focused on joint outcomes. The impact of prophylactic therapy on intracranial haemorrhage (ICH) is less known. This study aimed to analyse ICH in children with haemophilia, with a focus on different prophylaxis regimens and sequelae of ICH.

A Randomized Trial of Factor VIII and Neutralizing Antibodies in Hemophilia A.

Background: The development of neutralizing anti-factor VIII alloantibodies (inhibitors) in patients with severe hemophilia A may depend on the concentrate used for replacement therapy.

Methods: We conducted a randomized trial to assess the incidence of factor VIII inhibitors among patients treated with plasma-derived factor VIII containing von Willebrand factor or recombinant factor VIII. Patients who met the eligibility criteria (male sex, age <6 years, severe hemophilia A, and no previous treatment with any factor VIII concentrate or only minimal treatment with blood components) were included from 42 sites.

Spanish Consensus Guidelines on prophylaxis with bypassing agents in patients with haemophilia and inhibitors.

Prophylaxis with the blood clotting factor, factor VIII (FVIII) is ineffective for individuals with haemophilia A and high-titre inhibitors to FVIII. Prophylaxis with the FVIII bypassing agents activated prothrombin complex concentrates (aPCC; FEIBA® Baxalta) or recombinant activated factor VII (rFVIIa; Novo-Seven®, Novo Nordisk) may be an effective alternative. It was our aim to develop evidence -and expert opinion- based guidelines for prophylactic therapy for patients with high-titre inhibitors to FVIII.

Spanish consensus guidelines on prophylaxis with bypassing agents for surgery in patients with haemophilia and inhibitors.

Introduction: Patients with severe haemophilia and inhibitors against factor VIII who require surgery need a prophylactic approach to prevent bleeding complications. Scientific evidence to decide the best prophylactic treatment is very limited and mainly based on retrospective or case series.

Aims: To develop evidence- and expert opinion-based guidelines for prophylactic therapy for patients with haemophilia and inhibitors undergoing surgery.

Experience of Preimplantation Genetic Diagnosis for Hemophilia at the University Hospital Virgen Del Rocío in Spain: Technical and Clinical Overview.

Hemophilia A and B are the most common hereditary hemorrhagic disorders, with an X-linked mode of inheritance. Reproductive options for the families affected with hemophilia, aiming at the prevention of the birth of children with severe coagulation disorders, include preimplantation genetic diagnosis (PGD). Here we present the results of our PGD Program applied to hemophilia, at the Department of Genetics, Reproduction and Fetal Medicine of the University Hospital Virgen del Rocío in Seville.
