Article Synopsis
  • * A study involving 2,727 children showed that ICH occurred in 2.2% of cases, mostly before the age of one, with a significantly higher incidence in hemophilia A compared to hemophilia B.
  • * Early diagnosis of hemophilia is crucial, as 40% of ICH cases happened before the diagnosis, and preventive treatment could potentially lower the incidence of ICH if initiated promptly.

Adolescents with hemophilia are a patient population with special requirements, having to manage their condition alongside the typical challenges of adolescence. Given the psychosocial impact of hemophilia and a desire to fit in with non-hemophilic peers, they may perceive treatment as more of a burden than a benefit. This can result in low adherence and a high risk of hemophilia-related complications.

Acid Treatment of FVIII-Containing Plasma Samples Unmasks a Broad Spectrum of FVIII-Specific Antibodies in ELISA.

Hamostaseologie

October 2024

Department of Paediatrics and Adolescent Medicine, Clinical and Molecular Haemostasis, Goethe University Frankfurt, Frankfurt, Germany.

During routine treatment, plasma samples of patients with hemophilia A or acquired hemophilia A are frequently analyzed for the presence of FVIII-specific antibodies. While only inhibitory antibodies can be detected by the Bethesda assay, inhibitory and non-inhibitory antibodies can be detected by ELISA. However, plasma samples of patients frequently contain endogenous or substituted FVIII, hence interfering with both types of analyses.

Bleeding control improves after switching to emicizumab: Real-world experience of 177 children in the PedNet registry.

Haemophilia

May 2024

Center for Benign Haematology, Thrombosis and Haemostasis, Van Creveldkliniek, University Medical Center Utrecht, Utrecht University, Utrecht, The Netherlands.

Introduction: Despite the rapid uptake of emicizumab in the paediatric haemophilia A (HA) population, real-world data on the safety and efficacy is limited.

Aim: To report on bleeding and safety in paediatric patients receiving emicizumab prophylaxis.

Methods: Data were extracted from the multicentre prospective observational PedNet Registry (NCT02979119).

Patient perspective on living with mild hemophilia in Germany: results from a nationwide survey.

Front Med (Lausanne)

February 2024

Pediatric Thrombosis and Hemostasis Unit, Pediatric Hemophilia Center, Dr. von Hauner Children's Hospital, LMU München, Munich, Germany.

Introduction: The disease burden and bleeding risk of patients with mild hemophilia may be underestimated. Their health-related quality of life (QoL) may be negatively impacted by insufficient treatment and bleed-related joint damage connected to a potentially delayed diagnosis.

Aim: This study aims to gain information on the care reality and QoL of patients aged ≥12 years with mild hemophilia in Germany.

Article Synopsis
  • The study investigates the safety of intramuscular COVID-19 vaccinations in patients with haemophilia, who typically should receive subcutaneous vaccinations due to bleeding risks.
  • In part A, 461 haemophilia patients were monitored for injection site bleeding, resulting in a low bleeding rate of 1.5% within 30 days post-vaccination.
  • In part B, analysis showed that 97% of patients with severe haemophilia received prophylaxis before vaccination, and most bleeding incidents occurred in patients who were not on prophylaxis at the time.

The mainstay of hemophilia treatment is to prevent bleeding through regular long-term prophylaxis and to control acute breakthrough bleeds. Various treatment options are currently available for prophylaxis, and treatment decision-making is a challenging and multifaceted process of identifying the most appropriate option for each patient. A multidisciplinary expert panel convened to develop a practical, patient-oriented algorithm to facilitate shared treatment decision-making between clinicians and patients.

Prophylaxis in children with haemophilia in an evolving treatment landscape.

Haemophilia

November 2021

Department of Paediatric Haematology, Emma Children's Hospital, Amsterdam UMC, University of Amsterdam, Amsterdam, Netherlands.

Introduction: For children with haemophilia, early initiation of prophylaxis is crucial to prevent life-threatening bleeds and maintain joint health throughout life. Options for prophylaxis have recently increased from replacement therapy with standard or extended half-life coagulation factor products to include other haemostasis products, such as the non-replacement therapy emicizumab.

Aim: To review key factors that determine the choice of prophylaxis in young children.

First observation of inhibitor development against efmoroctocog alfa in France.

Transfus Apher Sci

August 2021

Department of Paediatrics, Clinical and Molecular Haemostasis, Frankfurt University Hospital, Frankfurt am Main, Germany.

In patients with severe haemophilia receiving clotting factor concentrates, the risk of immunisation against their usual treatment is still patent and feared. New haemophilia drug treatments with an extended half-life have become available over the past few years. The risk of inhibitor development to these new treatments is unclear.

Anti-factor VIII antibodies in brothers with haemophilia A share similar characteristics.

Haemophilia

March 2017

Department of Paediatrics, Clinical and Molecular Haemostasis and Immunodeficiency, University Hospital Frankfurt, Frankfurt am Main, Germany.

Introduction: The development of neutralizing antibodies (inhibitors) against coagulation factor VIII (FVIII) is currently the most serious complication for patients with haemophilia A undergoing FVIII replacement therapy. Several genetic factors have been acknowledged as risk factors for inhibitor development.

Aim: To analyze the influence of genetic factors on the nature of the humoral immune response to FVIII in eight brother pairs with inhibitors.

Article Synopsis
  • * Research reveals that several anti-C1 monoclonal antibodies (mAbs) exist, with distinct binding characteristics that affect how fVIII interacts with other molecules, such as von Willebrand factor (VWF) and phospholipids.
  • * Group A mAbs show weak inhibition of fVIII's function but significantly increase its clearance in the body, whereas Group B mAbs actively inhibit fVIII functionality and its interactions, contributing to the disease process in hemophilia A.

Epitope mapping via selection of anti-FVIII antibody-specific phage-presented peptide ligands that mimic the antibody binding sites.

Christoph Königs, MD PhD, University Hospital Frankfurt, Department of Paediatrics, Clinical and Molecular Haemostasis, Theodor-Stern-Kai 7, 60596 Frankfurt am Main, Germany, Tel.: +49 69 6301 83030, Fax: +49 69 6301 83991, E-mail:

The most serious complication in today's treatment of congenital haemophilia A is the development of neutralising antibodies (inhibitors) against factor VIII (FVIII). Although FVIII inhibitors can be eliminated by immune tolerance induction (ITI) based on repeated administration of high doses of FVIII, 20-30% of patients fail to become tolerant. Persistence of FVIII inhibitors is associated with increased morbidity and mortality.
