Thalassemia

Thalassemia Care in Grand Rapids, Michigan

Thalassemia is the most common inherited blood disorder in the world. It is caused by changes (mutations) in the genes that control hemoglobin production. Hemoglobin is the protein inside red blood cells that carries oxygen from your lungs to the rest of your body.

In Grand Rapids and across West Michigan, thalassemia is managed by hematology specialists at major health systems such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, University of Michigan Health-West (formerly Metro Health), and Trinity Health Grand Rapids. Early diagnosis and lifelong care are essential for keeping patients healthy, especially through Michigan’s long, cold winters, when infections and fatigue can be more challenging.

How Thalassemia Affects Hemoglobin and Causes Anemia

When the hemoglobin genes are altered, the body cannot make enough healthy hemoglobin. This leads to:

• Fewer red blood cells
• Red blood cells that break down too quickly
• Severe anemia (low red blood cell count)

Thalassemia can affect people of any nationality or ethnicity. It is especially common in people with:

• Mediterranean ancestry (e.g., Italian, Greek)
• Middle Eastern, Indian, Pakistani, or Southeast Asian backgrounds
• African or Latin American ancestry

In many cases, thalassemia is diagnosed in the first six months of life. Without ongoing treatment, severe forms can be life‑threatening in early childhood. In Grand Rapids, pediatric cases are often managed through children’s hematology services at Helen DeVos Children’s Hospital (Corewell Health).

Types of Thalassemia: Alpha and Beta

There are two main types of thalassemia, based on which hemoglobin genes are affected.

Alpha-Thalassemia

Alpha-thalassemia involves changes in two closely related genes called HBA1 and HBA2. These genes help your body make the alpha part of the hemoglobin molecule.

• More common in people from Africa, Asia, and the Middle East
• Can range from silent (no symptoms) to severe, depending on how many gene copies are affected

Beta-Thalassemia

Beta-thalassemia involves changes in the HBB gene, which helps make the beta part of hemoglobin.

• More common in people from Mediterranean countries, parts of the Middle East, and South Asia
• Severity depends on whether one or both copies of the HBB gene are changed

In a diverse city like Grand Rapids, MI, with growing immigrant and refugee communities, both alpha‑ and beta‑thalassemia may be seen in families with origins in these higher‑risk regions.

Thalassemia Minor (Carrier State)

Thalassemia minor describes people who carry genetic changes but usually have mild or no symptoms. This includes:

• One changed copy of the HBB gene (beta-thalassemia minor)
• One changed copy of HBA1 or HBA2, or one change in each (alpha-thalassemia minor)

Key points about thalassemia minor:

• Most carriers feel well and may only have mild anemia or small red blood cells
• Carriers can pass the gene to their children
• The only reliable way to know if you are a carrier is through specific blood tests and/or genetic testing

The World Health Organization estimates that 5–7% of the world’s population has thalassemia minor. In West Michigan, carriers are often discovered during routine blood work, prenatal care, or pre‑marital screening.

Thalassemia Major (Severe Disease)

Thalassemia major occurs when a person inherits changes in both copies of the affected gene(s). This means:

• There are no fully functioning copies of the gene
• The body cannot produce enough normal hemoglobin
• Severe, lifelong anemia develops

Thalassemia major can be:

• Alpha-thalassemia major
• Beta-thalassemia major (more common)

In thalassemia major:

• Red blood cells may survive only a few weeks, instead of the normal four months
• This leads to severe oxygen shortage in tissues and organs

Inheritance Risk for Children

If both parents are carriers of the same type of thalassemia, each pregnancy has:

• 25% chance the child will have thalassemia major
• 50% chance the child will be a carrier (thalassemia minor)
• 25% chance the child will not inherit the thalassemia gene at all

Because of these risks, pre‑pregnancy and prenatal genetic counseling are strongly recommended for at‑risk couples in Grand Rapids and across Michigan.

Symptoms of Thalassemia Major

Symptoms usually appear in early childhood, often within the first year of life. They may include:

• Severe anemia
• Pale or yellowish skin
• Poor appetite
• Sleep difficulties or unusual tiredness
• Failure to grow and gain weight properly (failure to thrive)
• Enlarged spleen and liver
• Bone changes (especially in the face and skull) over time

In Michigan’s colder months, fatigue, frequent infections, and breathing difficulties can feel worse for children with severe anemia, making regular follow‑up with a hematologist in Grand Rapids especially important.

Treatment for Thalassemia Major in Grand Rapids

Lifelong Treatment – No Simple Cure

There is currently no simple cure for thalassemia major. Treatment is lifelong and aims to:

• Maintain healthy hemoglobin levels
• Prevent complications from anemia and iron overload
• Support normal growth and development in children

Regular Blood Transfusions

The main treatment is regular blood transfusions, usually every 3–4 weeks. These transfusions:

• Boost hemoglobin levels
• Reduce symptoms of anemia
• Help children grow and stay active

In Grand Rapids, transfusions and specialized care are typically provided through:

• Corewell Health (Corewell Health) hematology and infusion centers
• Helen DeVos Children’s Hospital for pediatric patients
• Trinity Health Grand Rapids and University of Michigan Health-West hematology services

Iron Overload and Iron Chelation Therapy

Frequent transfusions cause iron to build up in the body (iron overload). Too much iron can damage vital organs and lead to:

• Diabetes
• Heart failure
• Liver disease
• Hormone problems (affecting growth and puberty)

To prevent this, patients are given iron chelation therapy.

Iron Chelators

Iron chelators are medications that:

• Bind to excess iron in the blood and tissues
• Help the body remove iron through urine or stool

They can be:

• Oral medications (taken by mouth)
• Injectable medications

Hematology teams in Grand Rapids will:

• Monitor iron levels with blood tests and imaging (e.g., MRI of the liver and heart)
• Adjust chelation therapy to keep iron at safe levels

How Thalassemia Is Diagnosed

Thalassemia is diagnosed using a combination of blood and genetic tests:

• Complete blood count (CBC): Checks red blood cell size, number, and hemoglobin level
• Hemoglobin electrophoresis or HPLC: Measures types of hemoglobin in the blood
• Iron studies: Help distinguish thalassemia from iron deficiency
• Genetic testing: Looks for specific changes in the HBA1, HBA2, and HBB genes

In Grand Rapids, testing can be arranged through:

• Your primary care provider or pediatrician
• Hospital laboratories at Corewell Health, Trinity Health Grand Rapids, University of Michigan Health-West – U of M Health, or Trinity Health Grand Rapids
• Referral to a genetic counselor or clinical genetics service

The Kent County Health Department and Grand Rapids Public Health can also provide information about local resources and referrals for families seeking genetic testing.

Pre‑Pregnancy and Prenatal Testing in Grand Rapids, MI

Who Should Consider Testing?

Couples should consider thalassemia testing if:

• One or both partners have family origins in a higher‑risk region (Mediterranean, Middle East, Africa, South or Southeast Asia, Latin America)
• There is a family history of thalassemia or “inherited anemia”
• Routine blood tests show unexplained small red blood cells or mild anemia

Testing can be arranged:

• Through your family doctor or OB/GYN
• By referral to genetic counseling services at major health systems in Grand Rapids

If You Are Already Pregnant

If you are pregnant and at risk:

• Speak with your OB/GYN or midwife about prenatal testing
• Options may include:
  • Testing both parents for carrier status
  • Testing the baby during pregnancy (prenatal diagnosis), if both parents are carriers

Options for Couples Who Are Both Carriers

If both partners are carriers of the same type of thalassemia, options may include:

• Natural conception and accepting the risk, with:
  • Prenatal diagnosis and the option to continue or terminate the pregnancy if the baby has thalassemia major (a deeply personal decision)
• Pre‑implantation genetic diagnosis (PGD):
  • Using in vitro fertilization (IVF) to create embryos
  • Testing embryos for thalassemia before transfer to the uterus
• Using donor sperm or donor eggs
• Adoption or fostering

Genetic counselors in Grand Rapids can help you understand:

• Your specific risks
• The pros and cons of each option
• Emotional, ethical, and cultural considerations

Bone Marrow Transplant for Thalassemia Major

At present, a bone marrow (stem cell) transplant is the only potential curative treatment for thalassemia major. However:

• The chance of finding a fully matched donor is around 30%
• Most suitable donors are siblings
• Transplant is more successful in younger children who do not yet have severe iron overload
• Risks include:
  • Graft rejection
  • Serious infection
  • Even death

Because of these significant risks, bone marrow transplantation is not suitable for every family. Children from Grand Rapids who are candidates are often referred to regional or national transplant centers with specialized pediatric bone marrow transplant programs.
