When you cut yourself, your body plugs up the wound with a blood clot. One of the essential factors used to form a blood clot - usually Factor VIII or IX - is missing in a person with haemophilia. This means they are prone to bleeding, especially internally.
Long-term effects of haemophilia
Haemophilia can be either mild, moderate or severe, according to the level of clotting factor deficiency. The lack of clotting factor means that people with haemophilia tend to bleed internally into joints and muscles. This can lead to chronic pain and arthritis.
Causes of haemophilia
Haemophilia is rare. It affects approximately 3,000 Australians - mostly men. It is mainly a male disorder because the haemophilia gene is carried on the X chromosome. It is passed on by females who carry the haemophilia gene and by males who have haemophilia. In around 30 per cent of cases, the condition occurs through a gene mutation in either the mother or fetus. This means haemophilia can occur in any family.
Treatment for haemophilia
Infusions (injections) of blood products are needed to stop internal bleeding. These infusions replace the missing clotting factor. They can be administered by a hospital that has an accredited haemophilia centre. Alternately, many people with haemophilia are taught to inject themselves at home
Until recently, treatment involved infusions of blood products only after the bleeding had started. These infusions eased the pain, but couldn’t stop the bleeding into joints. This means many men and boys with haemophilia have developed osteoarthritis, particularly in the hip, knee and ankle. Now all children with severe haemophilia are given preventative treatment with infusions of blood products before they have a bleed. This may mean that many people with haemophilia won’t develop arthritis in the future.
Injured muscles and joints need protection
When people with haemophilia bleed into a muscle or joint, they also need to:
- Rest the injured area.
- Apply ice packs to the affected area to reduce the swelling.
- Wrap bandages around the affected area to further ease swelling.
- Raise the injured limb, if possible.
