Thalassemia is a hereditary blood disorder in which the body produces an abnormal or insufficient amount of hemoglobin, the vital protein in red blood cells responsible for carrying oxygen throughout the body. As a result, red blood cells become fragile and break down prematurely (a process known as hemolysis), leading to chronic anemia, fatigue, poor growth, and, in severe cases, life-threatening complications.

For international patients, managing thalassemia in India is significantly more affordable compared to Western countries. The annual cost for regular blood transfusions and iron chelation therapy typically ranges between $2,000 and $5,000 USD, while a curative bone marrow transplant costs approximately $25,000 to $30,000 USD. This makes India a preferred destination for advanced yet cost-effective thalassemia care.

What is Thalassemia?

Thalassemia is a genetic blood disorder characterized by the body’s inability to produce adequate hemoglobin, leading to severe anemia. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Individuals with thalassemia have lower levels of hemoglobin and fewer red blood cells than those with normal levels, resulting in anemia that can cause fatigue, weakness, and other complications.

How Many Types of Thalassemia?

Thalassemia is a genetic disorder caused by mutations in the genes that produce hemoglobin, the oxygen-carrying protein in red blood cells. It is broadly classified into two main types based on which globin chain is affected:

1. Alpha Thalassemia

  • Cause: Mutation or deletion in one or more of the four alpha-globin genes on chromosome 16.

Subtypes:

Type Genes Affected Severity Clinical Features
Silent Carrier 1 gene missing Asymptomatic Normal blood count
Alpha Thalassemia Trait (Minor) 2 genes missing Mild anemia Often misdiagnosed as iron-deficiency
Hemoglobin H Disease 3 genes missing Moderate to severe Hemolytic anemia, hepatosplenomegaly
Hydrops Fetalis (Hb Bart's) 4 genes missing Fatal (in utero) Severe edema, heart failure, usually incompatible with life
  • Diagnosis: Hemoglobin electrophoresis, DNA analysis
  • Management: Transfusions for HbH disease, in-utero intervention for hydrops fetalis

2. Beta Thalassemia

  • Cause: Mutation in one or both beta-globin genes on chromosome 11.

Subtypes:

Type Genes Affected Severity Clinical Features
Beta Thalassemia Minor (Trait) One gene mutated Mild Slight anemia, often asymptomatic
Beta Thalassemia Intermedia Both genes were mutated (mild mutations) Moderate Anemia, splenomegaly, occasional transfusion needed
Beta Thalassemia Major (Cooley’s Anemia) Both genes are mutated (severe) Severe Life-threatening anemia requires regular transfusions, and growth delay
  • Diagnosis: Hemoglobin electrophoresis (↑ HbA2, ↑ HbF), CBC, iron studies
  • Management: Regular transfusions, iron chelation, bone marrow transplant (curative)

3. Other Variants of Thalassemia

Delta-Beta Thalassemia

  • A mutation in both the delta and beta-globin genes
  • ↑ HbF; milder than β-thalassemia major

Hemoglobin E Beta Thalassemia

  • Combination of HbE trait with beta thalassemia
  • Common in Southeast Asia
  • Variable severity: from mild anemia to transfusion dependence

Thalassemia with Other Hemoglobinopathies

  • HbS/Thalassemia (Sickle cell-thalassemia)
  • HbC/Thalassemia
  • Combined disorders may worsen symptoms or complicate treatment

Summary Table

Type Gene Involved Clinical Severity Treatment Needed
Alpha Thalassemia Silent Carrier α None None
Alpha Trait α Mild Rarely
HbH Disease α Moderate-Severe Occasional transfusions
Hb Bart's (Hydrops Fetalis) α Fatal In-utero management (rare)
Beta Thalassemia Minor β Mild None
Beta Thalassemia Intermedia β Moderate Sometimes
Beta Thalassemia Major β Severe Lifelong transfusions/transplant

How Is Thalassemia Diagnosed?

Initial Evaluation:

  • CBC (Complete Blood Count) – Microcytic anemia
  • Peripheral Smear – Target cells, hypochromia
  • Hemoglobin Electrophoresis or HPLC – Confirms diagnosis
  • DNA analysis – Optional, for prenatal or family planning

Additional Workups:

  • Ferritin levels (iron overload tracking)
  • Liver and kidney function tests
  • Cardiac evaluation (MRI T2* if iron overload suspected)
  • HLA typing – If considering bone marrow transplant

What Is the Standard Management for Thalassemia?

A. Regular Blood Transfusions

Goal: Maintain pre-transfusion Hb ≥ 9–10 g/dL

Frequency: Every 2–4 weeks

Precautions:

  • Leuko-depleted, phenotype-matched red cell units
  • Monitor for alloimmunization

B. Iron Chelation Therapy

Indication: Starts when serum ferritin >1000 ng/mL or after 10–20 transfusions

Options:

  1. Deferoxamine (Desferal) – Subcutaneous, 5–7 days/week
  2. Deferasirox (Exjade/Jadenu) – Oral, once daily
  3. Deferiprone (Ferriprox) – Oral, 3 times daily

Often used in combination for high iron burden

Monitoring: Ferritin levels every 3 months, yearly MRI T2* (heart/liver)

C. Supportive Care

  • Folic acid supplementation
  • Hepatitis B vaccination
  • Routine infection screening (HIV, Hep B/C)
  • Growth and puberty assessment
  • Endocrine evaluations (thyroid, glucose tolerance)

What Are the Curative Options?

A. Hematopoietic Stem Cell Transplant (HSCT)

Best Outcomes:

  • Matched sibling donor
  • Age < 7 years
  • Minimal organ damage

Protocol:

  • Conditioning regimen (Busulfan + Cyclophosphamide ± ATG)

  • Stem cell infusion (Bone marrow or peripheral blood)

Success Rate:

  • 90–95% with matched sibling donor
  • Lower with unrelated or mismatched donors

Post-Transplant:

  • Monitor for GvHD, infections, and engraftment success

B. Gene Therapy (Emerging)

  • Lentiviral-based gene addition (e.g., betibeglogene autotemcel)
  • Still expensive and available only in select centers
  • Not widely accessible in low-resource settings

Monitoring & Follow-Up Protocol

Parameter Frequency Notes
Hemoglobin Before each transfusion Target ≥ 9 g/dL
Ferritin Every 3 months Track iron overload
Liver/Kidney Function Every 6 months Detect chelator toxicity
MRI T2* Yearly Heart/Liver iron
Endocrine Panels Yearly Monitor for diabetes, hypothyroidism, etc.
Growth/Puberty Every 6 months in children Endocrine referral if delayed

Complications & Their Management

  • Iron Overload: Cardiac, hepatic, endocrine complications
    ➤ Address with intensified chelation and MRI monitoring

  • Alloimmunization: Use extended phenotype-matched blood

  • Infections: Especially if splenectomy is performed
    ➤ Prophylactic antibiotics & vaccinations

  • Delayed Growth & Puberty:
    ➤ Endocrine interventions, hormone therapy if needed

What Are the Causes of Thalassemia?

1. Genetic Mutation in Globin Genes

Thalassemia is caused by mutations or deletions in the genes responsible for producing hemoglobin, specifically the alpha-globin or beta-globin chains.

  • Hemoglobin (Hb) is made up of:
    • 2 alpha (α) chains
    • 2 beta (β) chains

Disruption in the production of either chain leads to imbalanced hemoglobin, causing red blood cells to break down more easily, resulting in anemia.

Types of Gene Defects:

  • Alpha Thalassemia: Missing or mutated α-globin genes (on chromosome 16)
  • Beta Thalassemia: Mutated β-globin genes (on chromosome 11)

2. Inheritance Pattern (Autosomal Recessive)

Thalassemia is inherited in an autosomal recessive pattern, meaning:

  • A person must inherit two faulty genes (one from each parent) to develop thalassemia major (the severe form).
  • If they inherit only one faulty gene, they are a carrier (thalassemia trait/minor) and usually have no or mild symptoms.

Inheritance Outcomes (When Both Parents Are Carriers):

Inheritance Chance Result
1 standard + 1 mutated gene 50% Carrier (Minor)
2 mutated genes 25% Thalassemia Major
2 normal genes 25% Healthy (Unaffected)

Frequently Asked Questions

With proper treatment, individuals with thalassemia can live into their 50s or 60s. The life expectancy largely depends on the type and severity of thalassemia and how well the disease is managed.

The only potential cure for thalassemia is a bone marrow or stem cell transplant. However, treatment can manage symptoms and improve quality of life.

Genetic counseling can help parents understand the risk of passing thalassemia to their children. Prenatal testing is also available to detect thalassemia in the fetus.

Frequent blood transfusions can lead to iron overload, which can damage the heart, liver, and other organs. Iron chelation therapy is used to manage this risk.
