Thalassaemia is a genetic blood disorder that affects the body’s ability to produce hemoglobin. 

World Thalassaemia Day was established by Thalassaemia International Federation (TIF) in 1994 and is observed every year on May 8th in memory of all patients who lost their lives to the disease and to honor those who are still fighting it.

This year the focus is to Empower Lives, Embracing Progress and Access to Quality Care for Every Patient.

What is Thalassaemia?

Thalassaemia is a genetic disorder that affects the body’s ability to produce hemoglobin. affect the body’s ability to produce hemoglobin. If a person inherits one faulty gene, they are a carrier, usually without symptoms. If both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit thalassaemia major, the severe form of the disease.

There are two main types of thalassaemia:

  • Alpha thalassaemia: It is caused by missing or mutated alpha-globin genes. Severity depends on how many of the four genes are affected. It can range from silent carrier status to a fatal condition (hydrops fetalis). More common in Southeast Asia, the Middle East, and Africa.
  • Beta thalassaemia: It is caused by mutations in the beta-globin gene, reducing or stopping beta-globin production. It leads to anemia of varying severity, from mild (trait) to severe (thalassaemia major), which requires regular blood transfusions. More common in Mediterranean regions, the Middle East, South Asia, and North Africa. Beta-thalassemia is more widespread and affects a larger number of people in India compared to alpha-thalassemia.

What are The Symptoms?

Symptoms vary by type, with thalassaemia major showing signs early in life due to severe anemia. Usual symptoms are fatigue, weakness, pale or yellowish skin, slow growth in children, dark urine, and facial bone deformities. Severe cases may cause enlarged spleen or liver and shortness of breath. 

How is it Diagnosed?

Thalassaemia is diagnosed through blood tests like a complete blood count (CBC), hemoglobin electrophoresis, and a peripheral blood smear. DNA testing confirms gene mutations. Prenatal tests like amniocentesis can detect thalassaemia in unborn babies.

How to Manage Thalassaemia?

Thalassaemia is managed through regular blood transfusions, iron chelation therapy and folic acid supplements. A healthy diet, monitoring for complications, and vaccinations definitely help. In some cases, a bone marrow or stem cell transplant might be needed. Genetic counseling helps prevent passing it to offspring.

Is it Preventable?

Thalassaemia is preventable through genetic screening and counseling. Couples can be tested before marriage or pregnancy to see if they are carriers. Public awareness campaigns help reduce new cases by educating communities about the importance of screening.

Conclusion:

Thalassaemia is a serious yet manageable genetic disorder. With advances in medical care and greater global awareness, we can improve the lives of those affected and work toward preventing the spread of this disease through informed decision-making and community support.
