Thalassemia (Blood Bio marker Disease)
Thalassemia
Thalassemia is an inherited blood disorder in which the body makes an abnormal form of hemoglobin. Hemoglobin is the protein molecule in red blood cells that carries oxygen. The disorder results in excessive destruction of red blood cells, which leads to anemia. Anemia is a condition in human body doesn’t have enough normal, healthy red blood cells.
Thalassemia is inherited, meaning that at least one of patient parents must be a carrier of the disease. It’s caused by either a genetic mutation or a deletion of certain key gene fragments.
Thalassemia minor is a less serious form of the disorder. There are two main forms of thalassemia that are more serious. In alpha thalassemia, at least one of the alpha globin genes has a mutation or abnormality. In beta thalassemia, the beta globin genes are affected.
The symptoms of thalassemia
The symptoms of thalassemia can vary. Some of the most common ones include:
Bone deformities, especially in the face
Dark urine
Delayed growth and development
Excessive tiredness and fatigue
Yellow or pale skin
Causes thalassemia
Thalassemia occurs when there’s an abnormality or mutation in one of the genes involved in hemoglobin production. You inherit this genetic defect from your parents.
If only one of your parents is a carrier for thalassemia, you may develop a form of the disease known as thalassemia minor. If this occurs, you probably won’t have symptoms, but you’ll be a carrier of the disease. Some people with thalassemia minor do develop minor symptoms.
The different types of thalassemia
There are three main types of thalassemia (and four subtypes):
Beta thalassemia, which includes the subtypes major and intermedia
Alpha thalassemia, which include the subtypes hemoglobin H and hydrops fetalis
Thalassemia minor
Beta thalassemia
Beta thalassemia occurs when your body can’t produce beta globin. Two genes, one from each parent, are inherited to make beta globin. This type of thalassemia comes in two serious subtypes: thalassemia major (Cooley’s anemia) and thalassemia intermedia.
Thalassemia major is the most severe form of beta thalassemia. It develops when beta globin genes are missing. The symptoms of thalassemia major generally appear before a child’s second birthday. The severe anemia related to this condition can be life-threatening. Other signs and symptoms include:
Fussiness
Paleness
Frequent infections
A poor appetite
Failure to thrive
Jaundice, which is a yellowing of the skin or the whites of the eyes
Enlarged organs
This form of thalassemia is usually so severe that it requires regular blood transfusions.
Thalassemia intermedia is a less severe form. It develops because of alterations in both beta globin genes. People with thalassemia intermedia don’t need blood transfusions.
Alpha thalassemia
Alpha thalassemia occurs when the body can’t make alpha globin. In order to make alpha globin, you need to have four genes, two from each parent.
This type of thalassemia also has two serious types: hemoglobin H disease and hydrops fetalis.
Hemoglobin H develops as when a person is missing three alpha globin genes or experiences changes in these genes. This disease can lead to bone issues. The cheeks, forehead, and jaw may all overgrow. Additionally, hemoglobin H disease can cause:
Jaundice
An extremely enlarged spleen
Malnourishment
Hydrops fetalis is an extremely severe form of thalassemia that occurs before birth. Most individuals with this condition are either stillborn or die shortly after being born. This condition develops when all four alpha globin genes are altered or missing.
Thalassemia minor
People with thalassemia minor don’t usually have any symptoms. If they do, it’s likely to be minor anemia. The condition is classified as either alpha or beta thalassemia minor. In alpha minor cases, two genes are missing. In beta minor, one gene is missing.
The lack of visible symptoms can make thalassemia minor difficult to detect. It’s important to get tested if one of your parents or a relative has some form of the disease.
Diagnosis of thalassemia
If your doctor is trying to diagnose thalassemia, they’ll likely take a blood sample. They’ll send this sample to a lab to be tested for anemia and abnormal hemoglobin. A lab technician will also look at the blood under a microscope to see if the red blood cells are oddly shaped. Abnormally shaped red blood cells are a sign of thalassemia. The lab technician may also perform a test known as hemoglobin electrophoresis. This test separates out the different molecules in the red blood cells, allowing them to identify the abnormal type.
Depending on the type and severity of the thalassemia, a physical examination might also help your doctor make a diagnosis. For example, a severely enlarged spleen might suggest to your doctor that you have hemoglobin H disease.
Treatment options for thalassemia
The treatment for thalassemia depends on the type and severity of disease involved. Your doctor will give you a course of treatment that will work best for your particular case.
Some of the treatments include:
Blood transfusions
Bone marrow transplant
Medications and supplements
Possible surgery to remove the spleen or gallbladder
Thalassemia affect pregnancy
Thalassemia also brings up different concerns related to pregnancy. The disorder affects reproductive organ development. Because of this, women with thalassemia may encounter fertility difficulties.
To ensure the health of both you and your baby, it’s important to plan ahead of time as much as possible. If you want to have a baby, discuss this with your doctor to make sure that you’re in the best health possible. Your iron levels will need to be carefully monitored. Preexisting issues with major organs are also considered.
Pregnancy carries the following risk factors in women with thalassemia:
A higher risk for infections
Gestational diabetes
Heart problems
Hypothyroidism, or low thyroid
Increased number of blood transfusions
Low bone density
Manage thalassemia
Since thalassemia is a genetic disorder, there’s no way to prevent it. However, there are ways you can manage the disease to help prevent complications. In addition to hepatitis vaccines and ongoing medical care, diet and exercise may also be helpful.
A low-fat, plant-based diet is the best choice for most people, including those with thalassemia. However, you may need to limit iron-rich foods if you already have high iron levels in your blood. Fish and meats are rich in iron, so you may need to limit these in your diet. You may also consider avoiding fortified cereals, breads, and juices. They contain high iron levels, too. Be sure to discuss any dietary changes with your doctor ahead of time.
You may ask your doctor for tips on exercising if you’re not currently physically active. Moderate-intensity workouts are best since heavy exercise can make your symptoms worse. Walking and bike riding are examples of moderate-intensity workouts. Swimming and yoga are other options, and they’re also good for your joints. The key is to find something you enjoy and keep moving.
