  1. Haemophilia The bleeding disorder. Amna Ghazali

  2. The Nature of Haemophilia Haemophilia is a hereditary disorder; meaning people are affected from birth. The most severe forms of haemophilia almost only affect males. Women can be seriously affected only if their father has haemophilia and their mother is a carrier, although this is extremely rare.  Many women who are carriers have symptoms of mild haemophilia, which can seriously affect their quality of life.

  3. The blood of a person with haemophilia does not clot normally because one or more of the plasma proteins needed to form a clot and stop the bleeding, is either missing or reduced. There are 13 main clotting factors (identified by roman numerals) that work together to produce a clot. If one factor is missing the chain reaction is broken; clots will not form properly, and bleeding will continue.

  4. A person with haemophilia will bleed for longer and in many cases will not stop without adequate treatment of factor replacement therapy. Small cuts on the skin aren’t usually a problem, but bleeding in any deeper area can be long-drawn-out. Superficial bruising, while appears dramatic, is often not a problem; it is internal bleeding that causes the most damage and can lead to complications. Some bleeding occurs as a result of injury (trauma), but some occur seemingly without cause (spontaneous), usually into a joint or a muscle. If untreated, bleeds can be life threatening, and immediate treatment is often necessary for bleeds in the head, throat, gut or groin.

  5. How common is haemophilia? • Haemophilia became widely publicised in European history due to Queen Victoria being a carrier of the disorder.  She passed haemophilia on to her son “Leopold”, and several of her daughters were carriers.  Her daughters were successful in passing haemophilia on to the royal families of Spain, Germany and Russia. Haemophilia is occasionally referred to as “the royal disease”; in reality it can affect anyone.

  6. Stats about Haemophilia • The most common type of haemophilia is factor VIII  deficiency, known as haemophilia A. Recent studies indicate that around 87% of haemophilia cases globally are haemophilia A. The second most common type is factor IX deficiency or haemophilia B. • Both haemophilia A and B are very rare disorders. Estimates indicate that approximately one in 10,000 males born in New Zealand has haemophilia. Recent studies suggest that around 300 New Zealand residents have haemophilia.

  7. There is no cure for haemophilia – it a chronic illness that will affect a person for their whole life. The life expectancy of someone with haemophilia and their quality of life varies greatly depending on whether they receive proper treatment. Without adequate treatment, many people with haemophilia die before they reach adulthood. However, with proper treatment, life expectancy for people with haemophilia is nearly that of males without haemophilia. However, there are still a range of challenges faced by a person with haemophilia throughout their lifetime.
