Thalassemia Treatment in India, Causes, Symptoms and Top Hospital

Thalassemias are split into two main categories. The categories are based on the part of hemoglobin that is affected:

• Alpha thalassemia—based on the alpha part of hemoglobin
• Beta thalassemia—based on the beta part of hemoglobin

Causes

Thalassemia is caused by faults in specific genes. It is an inherited disorder. This means the affected person received the faulty genes from the parents. The severity of the thalassemia will depend on the number of faulty genes that a child inherits. There are four genes needed for hemoglobin, two from each parent. The number of genes that are faulty will determine the severity and subtype of thalassemia:

• In alpha thalassemia
  • One abnormal gene—silent carrier, no signs of illness but can pass condition on to child
  • Two abnormal genes—Thalassemia trait, may have mild anemia
  • Three abnormal genes—Hemoglobin H disease, moderate to severe anemia
  • Four abnormal genes—most severe form called Alpha hydrops fetalis, results in fetal or newborn death
• In beta thalassemia
  • One abnormal gene—Thalassemia minor, carrier with mild anemia
  • Two abnormal genes—Thalassemia major (Cooley’s anemia), may have moderate to severe anemia

Risk Factors

Factors that increase your chance of Thalassemia include:

• Certain types of thalassemia are associated with ancestors from certain parts of the world:
  • Alpha thalassemias—Southeast Asia, Malaysia, and Southern China
  • Alpha hydrops fetalis—Southeast Asian, Chinese, and Filipino ancestry
  • Beta thalassemias—Africa, areas surrounding the Mediterranean Sea, and Southeast Asia
• A family history of the disorder

Symptoms

Silent carriers will have no symptoms. For others, symptoms most often begin within 3-6 months of birth.

Symptoms of mild or moderate anemia may include:

• Feeling weak and tired
• Shortness of breath
• Dizziness or headaches
• Cold hands and feet
• Pale skin

Symptoms of severe anemia include:

• Lack of interest in activity
• Pale appearance
• Poor appetite
• Dark urine
• Jaundice

General symptoms of thalassemia include:

• Slow growth and delayed puberty
• Enlarged and fragile bones, including:
  • Thickening and roughening of facial bones
  • Bones that break easily
  • Teeth that don’t line up properly

Thalassemia can also lead to complications such as:

• Increased risk of developing infections
• Enlarged spleen
• Heart failure
• Liver problems

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. Blood tests will be done to measure levels of:

• Hemoglobin
• Red blood cells
• Iron—needed to build hemoglobin

Treatment

Treatment will be based on the type and severity of anemia. Mild forms may not need treatment. More severe forms may need:

Prevention

This disease is inherited. Blood tests and family genetic studies will show if you are a carrier. A genetic counselor can discuss the risks of passing on the disease.
