Have you ever seen or heard of a condition where some people, especially young children, suddenly experience a severe loss of blood, feel very tired, and can sometimes be life-threatening? That is one of the serious conditions we are going to talk about today, called aplastic crisis . Although this name may sound a bit scary, if we are aware of it, we can cope with this condition well.
What exactly is this aplastic crisis?
Simply put, aplastic crisis is when the bone marrow in our body suddenly stops producing new red blood cells . Now you might be thinking, "So what happens if red blood cell production stops?" These red blood cells are what carry oxygen throughout our bodies. So when they stop producing, the number of red blood cells in the body decreases significantly, causing severe anemia . This is a condition that can be life-threatening.
Aplastic crisis usually affects people with blood disorders like sickle cell anemia . The main cause of this is a common viral infection called Parvovirus B19 . Don't be surprised, although this virus affects many people, aplastic crisis only occurs when people with blood disorders become infected with this virus. This condition is more common in young children, especially babies. But there is good news, there are treatments for this such as blood transfusions and intravenous immunoglobulin (IVIG) .
Is this a disease that affects everyone?
No, not at all. As I said before, Parvovirus B19 is a very common virus. However, not everyone infected with this virus develops aplastic crisis. This only happens when someone with a certain blood disease is infected with Parvovirus B19.
Newborns, infants, and children with sickle cell anemia are particularly at risk. People with other conditions that cause red blood cell destruction and hemolytic anemia are also at increased risk of developing an aplastic crisis if they become infected with parvovirus B19. Some of these conditions include:
- Hereditary Spherocytosis
- Hemoglobin C disease
- Thalassemia
- G6PD deficiency syndrome
- Pyruvate Kinase deficiency
- Autoimmune Hemolytic Anemia
- Paroxysmal Nocturnal Hemoglobinuria
- Hereditary Elliptocytosis
If you or your child has this type of blood disease, it is very important to take special care of this.
What are the symptoms of an aplastic crisis?
Adults, as well as children and infants, who have an aplastic crisis, usually have symptoms related to severe anemia. Babies and young children may be more fussy or irritable than usual. For example, if your child is crying a lot, doesn't like anything, or seems to be getting angry all the time, this could be a sign of something like this.
Here are some of the main symptoms:
- Fatigue: Feeling extremely tired, unable to do anything.
- Fever: Body temperature may reach 38 degrees Celsius (101 degrees Fahrenheit) or higher.
- Dizziness: It feels like your head is spinning, and your eyes may even turn blue.
- Shortness of breath / dyspnea: Shortness of breath even when moving a little, feeling very tired when climbing stairs.
- Irregular or rapid heartbeat: The heartbeat may be faster than usual, or it may be irregular and not beat in one direction.
- Pallor: The skin, lips, gums, or nails become paler than usual. This is the color seen when there is a lack of blood.
If you notice one or more of these symptoms, especially if you or your child has a blood disorder, it is very important to seek medical advice immediately .
Why does this aplastic crisis occur? What is the cause?
The word "aplastic" means that something in your body has stopped working. That's what happens in this aplastic crisis. Your bone marrow can't produce healthy red blood cells. The reason for that is the Parvovirus B19 that I mentioned earlier. This virus directly targets immature red blood cells that haven't yet matured. It damages them.
Our body gets things like red blood cells, some white blood cells, and plasma from the bone marrow. So when the continuous production of red blood cells stops, you develop severe anemia . Imagine, this is what happens when our body's blood factory suddenly stops working.
What are the possible complications of this condition?
Aplastic crisis can lead to various complications, especially in people with sickle cell anemia . These are also very serious.
- Prolonged Vaso-occlusive crisis (VOC):VOC is a sudden, severe pain that occurs in people with sickle cell anemia. This pain can last longer due to aplastic crisis.
- Myocarditis: This is an inflammation of the heart muscle, which is a swelling-like condition.
- Splenetic sequestration: Abnormal red blood cells become trapped in the spleen, causing the spleen to enlarge.
- Glomerulonephritis: This is a kidney disease that, if not treated properly, can lead to kidney failure.
That's why we say it's very important to be aware of this situation.
How do doctors recognize this?
When you or your child shows these symptoms, when you see a doctor, he or she will first ask you about your symptoms. Then he or she will do a physical examination. In addition, several tests may be done to confirm the condition:
- Complete Blood Count (CBC): This checks the number of red blood cells, white blood cells, and platelets in the body. In aplastic crisis, the number of red blood cells is very low.
- Reticulocyte count: Reticulocytes are immature red blood cells. This test measures how many new red blood cells are being produced by the bone marrow. In aplastic crisis, this number is also very low.
- Parvovirus B19 test: This test is done to confirm whether you have been infected with this virus.
After these tests, the doctor can tell for sure whether this is truly an aplastic crisis or something else.
What are the treatments for this?
The main treatment for aplastic crisis is blood transfusions . This means giving blood from outside. This can quickly restore the body's low red blood cell count. In addition, a treatment called Intravenous Immunoglobulin (IVIG) is given. This is given into the body through a vein (IV).
Most patients recover within 10 to 14 days of starting treatment. Another good thing is that once someone has been infected with parvovirus B19, they develop lifelong immunity to the virus. This means that the risk of developing an aplastic crisis from the virus again is greatly reduced.
Is there a way to prevent aplastic crisis?
It's actually a little hard to say. Because, aplastic crisis occurs when a person with a blood disorder is infected with parvovirus B19 . Parvovirus B19 is a very common virus, and there is no vaccine against it yet.
But, for you and your childIf you have a blood disorder like sickle cell anemia, it's important to ask your doctor what you can do to reduce your risk of contracting parvovirus B19. For example, simple things like staying away from crowded places and washing your hands frequently can provide some protection.
What will happen after this situation? (Prognosis)
Prognosis is the expected outcome for your condition. People with aplastic crisis usually recover within 10 to 14 days of starting treatment. However, some people may have recurring aplastic crises. Therefore, it is important to pay attention to the symptoms and follow your doctor's instructions.
How should I take care of myself? / How should I take care of my child?
Aplastic crisis is just one of many complications that can occur with blood diseases like sickle cell anemia . You may not be able to prevent parvovirus B19, but there are things you can do to maintain your overall health:
- Get regular checkups: By staying in regular contact with your primary care physician, you can identify serious medical complications before they occur.
- Reduce your risk of infection: Talk to your doctor about ways to protect yourself from common infections like influenza and the common cold.
- Eat a healthy diet: Eat a balanced diet and drink about 8-10 glasses of water a day.
- Exercise: Regular physical activity can improve your mood and health. But, take it slow, rest when you feel tired, and remember to drink plenty of water.
These things help keep your body's immune system strong and help you stay healthy in general.
When should I see a doctor?
Aplastic crisis is a medical emergency.
If you or your child has a blood disorder like sickle cell anemia , and you experience sudden changes in your health, such as feeling weak or extremely tired , you should see your doctor immediately, without delay. The sooner you start treatment, the better.
What questions should I ask the doctor?
If you or your child has an aplastic crisis, you can ask your doctor questions like these:
- When will I/my child get better?
- What are the chances that I/my child will have a crisis like this again?
- What are some things I should be especially careful about while living with this condition?
It is very important to ask questions like these and clear your doubts.
Are aplastic crisis and aplastic anemia the same thing?
Yes, although both of these conditions are associated with a decrease in red blood cell count, there is a difference between the two.
Aplastic crisis is a sudden, sudden drop in the number of red blood cells.
Aplastic anemia is a condition that develops gradually over time. In this, not only red blood cells but also other types of blood cells (white blood cells, platelets) may decrease.
Simply put, Aplastic Crisis is a temporary, acute problem. Aplastic Anemia is a long-term, bone marrow-specific problem.
Finally, take-home message
Okay, so I hope you now have a better understanding of what we talked about today, Aplastic Crisis. This is a serious complication that can affect people with blood diseases like Sickle Cell Anemia . What happens is that your or your child's bone marrow suddenly stops producing red blood cells, causing severe anemia that can be life-threatening.
Aplastic crises can be a scary experience because the symptoms can come on suddenly and be severe. Fortunately, doctors can treat it with blood transfusions and medication.
If you or your child has a blood disorder that puts you or your child at high risk of developing an aplastic crisis, ask your doctor what symptoms might indicate a problem. You may not be able to prevent an aplastic crisis, but you will know what to do if it happens. That awareness is the most important thing.
👩🏽⚕️ Additional questions (FAQs)
💬 What is Aplastic Crisis?
Our body's red blood cells are made in the bone marrow. For some reason, especially after a viral infection (such as Parvovirus B19), the sudden cessation of red blood cell production in our bone marrow for several days is called 'aplastic crisis'.
💬 What happens to the patient when the body suddenly stops making blood?
Red blood cells carry oxygen throughout the body. When they stop, the patient develops severe anemia. The lips, nails, and skin turn completely white (pale), the heart rate increases, or the patient suddenly loses consciousness due to difficulty breathing.
💬 What are the treatments for people like this, especially children?
This condition is most dangerous for children with sickle cell disease. If you are hospitalized for this condition, the hospital will immediately perform a blood transfusion. Usually, after this blood transfusion, the bone marrow starts making blood normally again in about 10 to 14 days.
