Do you often feel tired and lifeless? Sometimes we think that this is normal, a fatigue that comes from overwork. However, there may be a serious reason hidden beneath this fatigue. Today we are going to talk about such anemia, or a special condition related to a lack of blood in the body. This is called Heinz Body Anemia.
Simply put, what are these Heinz Bodies?
To understand this, we first need to know a little about our blood. Our blood contains a type of cell called red blood cells. These are the cells that carry oxygen throughout our bodies. Think of these red blood cells as little trucks that transport oxygen. The main part of these trucks that carries oxygen is called hemoglobin . This protein called hemoglobin is what gives our blood its red color.
However, for some reason, these hemoglobin molecules can become damaged. Just like the loading dock of a truck gets damaged. The damaged hemoglobin clumps together, clumps together, and sticks to the wall of the red blood cell. We call those clumps Heinz Bodies .
These Heinz bodies cause the red blood cells to lose their flexibility and become stiff. Normally, healthy red blood cells can easily pass through even the thinnest blood vessels. But these stiff cells have a hard time doing so. Our spleen is an organ that cleans our blood. As it passes through this filter, the spleen recognizes the red blood cells with these stiff Heinz bodies and destroys them. Sometimes, only the Heinz body part is removed, and the red blood cells look like someone has bitten off a piece of a biscuit. We also call these bite cells .
In this way, when these damaged red blood cells break down faster than our body can make new ones, the amount of blood in our body decreases. That's what we call Heinz Body Anemia.
Why does this situation occur? What are the reasons?
The main cause of Heinz bodies is chemical or oxidative damage to our red blood cells. This can be acquired after birth, or it can be caused by a congenital condition.
Causes that occur after birth
These are mainly caused by things that enter the body from outside.
| Reason | Description and examples |
|---|---|
| Some drugs and chemicals | Exposure to certain medications and chemicals can damage red blood cells. Examples:
|
| Mineral deficiencies | Selenium is an essential mineral for our body. It helps to make a powerful antioxidant called glutathione. This antioxidant is what protects our red blood cells from damage. If there is a selenium deficiency, this protection is reduced and Heinz bodies can form. |
Congenital causes (genetic conditions)
These are genetic conditions that are inherited from parents to children.
- G6PD deficiency: The full name of this is Glucose-6-phosphate dehydrogenase deficiency. This is a condition that is also seen in our country. This G6PD is a very important enzyme that protects red blood cells. In people who are deficient in this enzyme, when they take certain medications, when they get certain infections, or when they eat certain foods (e.g. fava beans), their red blood cells start to break down rapidly.
- Thalassemia: This is also a genetic defect in hemoglobin production that is common in our country. Heinz bodies can also be seen in the blood of thalassemia patients.
- Unstable hemoglobinopathies: Some people are born with abnormal, unstable forms of hemoglobin. These are easily damaged and cause Heinz bodies.
Do you also have these symptoms?
The presence of Heinz bodies does not cause symptoms. However, when a large number of red blood cells begin to break down, anemia develops and various symptoms may appear.
| Common symptoms of Heinz body anemia | |
|---|---|
| Yellowing of the skin and eyes (Jaundice) | Frequent feeling of extreme fatigue and exhaustion |
| Difficulty breathing and wheezing | Pale skin |
| Irregular or rapid heartbeat | Swollen liver or spleen (pain in the upper abdomen) |
How exactly do you find this? What tests are done?
If you have these symptoms, the first thing your doctor will do is examine you and order some blood tests.
- Complete Blood Count (CBC): This measures the number of red blood cells, white blood cells, and platelets in your blood. This is essential to check for anemia.
- Hemoglobin and Hematocrit: This also measures the number of red blood cells and hemoglobin levels.
- Peripheral Blood Smear: This is a very important test. Here, a drop of blood is smeared on a glass slide and examined under a microscope. Then, the shape and size of the red blood cells can be seen. The "bite cells" we talked about earlier can also be seen with this test. To see Heinz bodies directly, a special dye (stain) must be used for this test.
- Urine test: When red blood cells break down, hemoglobin can be released into the urine. This test is done to see if it is present.
What are the treatments?
Treatment depends on the cause of the condition. Your doctor will determine the cause and provide the most appropriate treatment.
- Stopping the causative medication: If it is determined that a medication is causing the condition, that medication will be stopped and, if necessary, a safer medication will be given instead.
- Providing nutritional supplements: If this condition is caused by a lack of a mineral such as selenium, supplements will be provided for that.
- Antibiotics: If anemia is aggravated by an infection.
- Blood Transfusion: If anemia is severe, a blood transfusion may be needed to quickly restore blood levels.
- Spleen Removal: In some severe cases, surgical removal of the spleen, which is the main site of red blood cell destruction, may be recommended.
- Treatments such as immune suppressing medicines and stem cell transplants may also be used in very rare and severe cases.
Most importantly: Never stop taking any medication or change the dosage without talking to your doctor. It can be dangerous.
What complications can occur due to this condition?
If Heinz body anemia is not managed properly, certain complications can occur. These vary depending on the cause and treatment of the disease.
- Blood clots (especially in the lungs)
- Gallbladder stones
- Kidney failure
- Heart failure
- Shock
- Side effects of medications taken for treatment
Some of these complications are medical emergencies. Therefore, if you suddenly feel unwell, have severe difficulty breathing, or experience chest pain, go to the Emergency Department (ETU) of the nearest hospital immediately. If you suspect that this condition has been caused by ingestion of a chemical substance, you can also call the National Poisons Information Centre at the Colombo National Hospital for advice.
Take-Home Message
- Heinz Body Anemia is a condition in which the body breaks down red blood cells faster than it can make new ones.
- This can be caused by certain medications, chemicals, or congenital conditions like G6PD deficiency and thalassemia.
- The main symptoms are frequent fatigue, yellowing of the skin, and pallor.
- Blood tests are essential to accurately diagnose this condition.
- Treatment depends on the cause of the disease, so it is very important to seek medical advice.
- Do not stop taking any medication without consulting a doctor. If you experience any discomfort, contact your doctor immediately.
