Does your little one seem tired all the time? Doesn't he/she like to eat much? Has he/she noticed that he/she is a little paler than other children? Although these may seem like normal things, sometimes there could be a rare condition behind this that we don't hear much about. Today we are going to talk about one such rare condition, but if managed properly, you can live with it successfully. That is Diamond-Blackfan Anemia, or `(Diamond-Blackfan Anemia - DBA)`.
Simply put, what is Diamond-Blackfan Anemia (DBA)?
Imagine that we have a big factory inside our bodies that makes blood. We call it the bone marrow . The main job of this factory is to make red blood cells, the little workers that carry oxygen throughout our bodies. DBA is a condition in which this factory called the bone marrow cannot make enough red blood cells. This is very rare, meaning that this condition occurs in about one in 500,000 children.
This is a genetic disorder . This means that it is caused by a change in the genes in our body's cells. This causes a decrease in the number of red blood cells in the body. We call this condition anemia , or blood deficiency or anemia. DBA is a lifelong condition. But don't worry, with good treatment, many people can control their symptoms and live a good life .
What are the symptoms of someone with DBA?
The symptoms of DBA can vary from person to person. Some people may experience mild symptoms, while others may experience more severe symptoms. Let's take a look at the main symptoms.
| Symptom | A simple explanation |
|---|---|
| Frequent fatigue | Because the body's cells do not receive the necessary amount of oxygen, you often feel sleepy and have no energy to do anything. |
| Paleness of the skin (Pallor) | The skin, lips, and nails appear pale due to a lack of red blood cells, which are responsible for the red color of the blood. |
| Rapid heartbeat (Tachycardia) | The heart has to work harder to pump the blood faster and provide the body with the oxygen it needs. |
| Difficulty breathing | Sometimes, like when walking a short distance or climbing a flight of stairs, I find it hard to breathe, and I feel like I'm gasping for breath. |
| Appetite | Especially young children who are not very interested in eating. |
| Headache and weakness | A common condition caused by insufficient oxygen to the body and brain. |
Why does this kind of disease occur? What is the cause?
As we discussed earlier, this is a genetic disease. There are specific genes in our body that instruct us to make red blood cells. They are called `(ribosomal protein genes)`. A person with DBA has a variation or mutation in these genes. As a result, the process of making red blood cells does not happen properly.
The important thing is that it can be passed down from parents to children. But this only happens in a small percentage, about 10% - 25%. In many cases, a child can develop the condition even if no one in the family has the disease, due to a random genetic mutation.
What other complications can occur due to DBA?
DBA doesn't just affect red blood cells. Sometimes it can cause other health problems as well. Also, people with DBA have a slightly higher risk of developing certain types of cancer than the general population.
| Type of complication | Description |
|---|---|
| Common complications | |
| Birth defects | There may be some problems with the heart, kidneys, or limbs. |
| Growth faltering | Physical growth is slower than expected for age. |
| Iron overload | Frequent blood donation can cause the body's iron levels to rise unnecessarily, damaging organs such as the heart and liver. |
| Decrease in other blood cells | Sometimes other blood cells, such as white blood cells (neutropenia) or platelets (thrombocytopenia), may also be low. |
| Cancer risk (slightly higher) | |
| Leukemia | Especially a type of blood cancer called ``Acute myeloid leukemia - AML``. |
| Myelodysplastic syndrome (MDS) | Another blood disease that impairs the function of the bone marrow. |
| Osteosarcoma | A cancer condition that occurs in the bones. |
How do doctors accurately diagnose this disease?
If your child has these symptoms, your doctor will first examine your child carefully and ask you about the details. Then, they may do some tests to confirm the diagnosis.
- Complete Blood Count (CBC): This measures the number of red blood cells, white blood cells, and platelets in the blood. A person with DBA has a very low red blood cell count.
- Reticulocyte count: Reticulocytes are newly formed red blood cells that are not yet fully mature. A low number means that the bone marrow is not producing enough new red blood cells.
- Bone marrow aspiration and biopsy: This is the main test used to confirm the disease. In this, a very small sample of bone marrow is taken, usually from the hip bone, under anesthesia. It is then examined under a microscope to determine exactly how much red blood cell production is occurring.
What are the treatments for DBA?
Although DBA cannot be completely cured, there are effective treatments that can help control symptoms and maintain a good quality of life.
1. Corticosteroids: These medications stimulate the bone marrow to produce more red blood cells. This treatment is successful for many patients.
2. Blood transfusion: People with very low blood counts are given red blood cells from a healthy donor. Doctors can start this treatment as soon as the disease is diagnosed. This provides quick relief from symptoms.
3. Stem cell transplant: This is the only treatment that can completely cure DBA. However, this is a very complex and risky treatment. In this, stem cells from the bone marrow of a healthy person (usually a family member) are transplanted into the patient. This is not possible for everyone. The doctor studies the patient's condition thoroughly, finds the best match, and makes this decision after a lot of thought.
What to do in an emergency?
If you or your child has DBA, it is very important to stay in touch with your doctor. It is important to keep appointments and take your medications as prescribed. If your symptoms get worse (for example, you are more tired than usual, you get more infections), tell your doctor right away.
Also, if you experience any of the following emergency symptoms, go to the nearest hospital Emergency Department (ETU) immediately .
- Severe chest pain
- Sudden severe stomach pain
- Sudden severe headache, confusion, or difficulty speaking (these may be signs of a stroke)
- Uncontrollable bleeding
Living with a lifelong and rare condition like DBA, especially if it's your child, can be very difficult. It can feel lonely. But remember, you're not alone. Your doctor and medical team will provide you with the support and guidance you need.
Take-Home Message
- Diamond-Blackfan anemia (DBA) is a rare genetic disease that prevents the bone marrow from making enough red blood cells.
- Frequent fatigue, paleness, and shortness of breath are the main symptoms.
- Although this is a lifelong condition, it can be successfully managed with treatments such as steroid medications and blood transfusions.
- It is essential to stay in regular contact with your doctor and receive the appropriate tests and treatment.
- Be aware of emergency warning signs (such as severe chest pain, loss of consciousness) and go to the hospital's Emergency Treatment Unit (ETU) immediately in such a case.
- Even if you feel isolated because this is a rare disease, remember that there are medical teams and support networks to support you.
