Key Points about Haemophilia B:
- Definition: Haemophilia B is an inherited bleeding disorder caused by a deficiency of clotting factor IX. This leads to prolonged bleeding episodes, typically following injury or surgery.
- Causes: Haemophilia B is a genetic disorder passed down through the X chromosome, making it more common in males. It is caused by mutations in the F9 gene.
- Symptoms: Symptoms include spontaneous bleeding into joints and muscles, easy bruising, and excessive bleeding after injury or surgery. Severe cases may present with frequent, spontaneous bleeds.
- Diagnosis: Diagnosis is based on blood tests that show low levels of clotting factor IX. Genetic testing can confirm the mutation responsible for the condition.
- Management: The main treatment is factor IX replacement therapy, which can be administered on-demand for bleeding episodes or prophylactically to prevent them. In some cases, newer therapies such as gene therapy may be considered.
- Complications: If untreated, repeated bleeding into joints can lead to chronic joint damage (haemophilic arthropathy). Other complications include the development of inhibitors against factor IX, making treatment more difficult.
