Thalassemia is a disease that is genetically transferred. Often, parents may be the carriers, but they may not suffer from the disease itself. But the children remain at risk. Babies that are born with a severe version of this disease often die before or shortly after birth.
As such, there is no cure for thalassemia. The only way that patients can cope with this disease is via blood transfusions. These can be as often as once every 2 - 3 weeks. Blood transfusion is also accompanied by iron chelation therapy. Transplanting bone marrow cells has shown positive results in some cases.
The cause of thalassemia is always genetic. It is an inherited disease. Either or both the parents are the carriers of the disease. Those who are carriers often have only one parent who has the disease, while the other parent is normal. These individuals often suffer from anaemia, but do not suffer from thalassemia. However, these genes are passed onto their children.
There are two types of haemoglobin protein chains-alpha globin chains and beta globin chains. Those who have a problem with the alpha globin chains are said to suffer from Alpha thalassemia, and those with a problem with the beta globin chain are said to suffer from Beta thalassemia.
The symptoms are often dependent upon the severity of the disease. The most common symptom is, of course, anaemia. The carriers do not show any symptoms at all. However, those suffering from severe thalassemia may often show the following symptoms:
An estimated 60 - 80 million people in the world are carriers of thalassemia. In the next 50 years, this disease is going to present a huge problem to mankind. Blood banks and the health system in general are looking at the possibilities very seriously. The only way one can prevent the spread of thalassemia is via genetic counselling and genetic testing
It has therefore been suggested that before getting married or before planning a pregnancy, both the parents get their blood tested in order to assess and understand if the future child is in danger of contracting the disease or not.
