From the Guidelines
Managing hemophilia in patients with liver disease requires careful coordination between hematology and hepatology specialists, with a focus on regular monitoring of coagulation factors and liver function, and individualized treatment based on bleeding risk, factor levels, inhibitor status, and liver disease severity. The approach should prioritize the patient's specific needs, taking into account the liver's synthetic function and its impact on factor production and clearance. For hemophilia A patients, recombinant factor VIII concentrates are preferred at doses typically ranging from 20-50 IU/kg depending on bleeding severity, while hemophilia B patients require factor IX concentrates at 20-100 IU/kg 1.
In patients with liver disease, dosing may need adjustment, and non-factor replacement options like emicizumab (1.5 mg/kg weekly maintenance) for hemophilia A or bypassing agents such as recombinant factor VIIa (90 μg/kg every 2-3 hours as needed) may be beneficial, particularly when inhibitors develop 1. Antifibrinolytics like tranexamic acid (1-1.5 g orally three times daily) can help with mucosal bleeding. Liver disease complicates management because it can cause both bleeding and clotting tendencies simultaneously, with decreased production of coagulation factors alongside reduced production of natural anticoagulants.
Regular assessment of both factor levels and liver function tests is essential, with treatment individualized based on bleeding risk, factor levels, inhibitor status, and liver disease severity 1. The most recent guidance from the European Association for Haemophilia and Allied Disorders, European Haemophilia Consortium, ISTH, and World Federation of Hemophilia emphasizes the importance of protecting liver health in people with bleeding disorders and optimizing the prevention and management of liver complications 1.
Key considerations in managing hemophilia in patients with liver disease include:
- Regular monitoring of coagulation factors and liver function
- Individualized treatment based on bleeding risk, factor levels, inhibitor status, and liver disease severity
- Adjustment of dosing for factor replacement therapy based on liver synthetic function
- Consideration of non-factor replacement options and antifibrinolytics as needed
- Close collaboration between hematology and hepatology specialists to optimize patient care 1.

From the Research
Management of Hemophilia in Patients with Liver Disease
- Hemophilia patients who develop liver disease require careful management to prevent bleeding complications and ensure optimal treatment outcomes 2, 3, 4, 5, 6.
- Liver transplantation can be considered as a definitive therapy for hemophilia A and/or B with transfusion-related liver disease, as it can provide a long-term phenotypic cure for hemophilia 2, 5.
- Gene therapy for severe hemophilia A uses an adeno-associated virus (AAV) vector and liver-specific promoters, and hepatocyte health is essential for safe and successful gene therapy 3.
- Patients with hemophilia who are co-infected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) can exhibit a rapid progression of liver disease, and treatment of HCV-infected patients is targeted towards preventing the progression of early cirrhosis and end-stage liver disease 4.
- Thromboelastography can be a useful tool for real-time analysis of clot formation and guiding the perioperative administration of blood products in hemophilic patients undergoing liver transplantation 5.
Treatment Options
- Orthotopic liver transplantation can be used to treat hemophilia A and/or B with transfusion-related liver disease, and factor VIII and factor IX levels can return to normal within 24 hours after transplantation 2.
- Gene therapy for hemophilia A requires close monitoring of liver function tests and factor levels, and routine screening for hepatocellular carcinoma is essential in patients at high risk 3.
- Treatment of HCV-infected patients with hemophilia can involve the combination of standard interferon-alpha (IFN-alpha) with ribavirin for at least 6 months, and data on the use of PEGylated IFN are emerging 4.
- Recombinant factor IX and thromboelastography can be used to manage coagulopathy in patients with hemophilia B undergoing liver transplantation 5.
Monitoring and Follow-up
- Close follow-up is necessary to determine chronic liver disease and its further therapy in patients with hemophilia 6.
- Liver biopsy and morphologic evaluation of tissue remain the current "gold standard" for assessing the severity of HCV-induced liver disease, although radiographic techniques such as computerized tomography or magnetic resonance imaging can also be used 4.
- Routine screening for hepatocellular carcinoma is essential in patients at high risk, and thromboelastography can be used to monitor the ability of high-purity FIX supplementation to restore a normal coagulation state 3, 5.
