Thalassemia is an
inherited blood disorder that causes the body to produce fewer healthy blood
cells and less hemoglobin and iron-rich protein in red blood cells. There are
two types of thalassemia.
• Alpha thalassemia
Alpha thalassemia
major or hydrops fetalis is known as the most severe form of alpha
thalassemia.
• Beta-thalassemia
The most severe form
of beta-thalassemia is known as beta-thalassemia major or Cooley’s anemia.
Causes
Haemoglobin in red
blood cells has two kinds of protein chains,
<!--[if !supportLists]-->·
<!--[endif]-->Alpha-globin
<!--[if !supportLists]-->·
<!--[endif]-->Beta-globin
If your body is unable
to make enough of these protein chains, red blood cells will not be formed
properly and will not be able to carry enough oxygen. Genes in our body control
how our body makes haemoglobin protein chains. When these chains are missing or
altered, thalassemia occurs.
Signs and symptoms
Symptoms of thalassemia are caused by a lack of
oxygen in the bloodstream because in thalassemia the body doesn’t make enough
healthy red blood cells and haemoglobin. Some of the most common symptoms of
thalassemia are:
• Anemia
• Slowed growth
• Delayed puberty
• Bone problems
• An enlarged spleen
Treatment:
Treatment of
thalassemia depends on the type and severity of the problem. People with alpha
and beta-thalassemia probably don’t need treatment. But if their problem is
major, then there are three treatments available for them.
1. Frequent blood transfusion.
2. Chelation therapy.
3. Stem cell transplant
