Are your blood cells low? Let's talk about cytopenia!

Do you sometimes just feel tired and lethargic? Or do you get sick all the time? Maybe this is because you have a low number of certain types of cells in your blood. In medicine, we call this condition cytopenia. Don't worry, let's talk about it simply.

What types of cells are in our blood? What happens if they decrease?

Okay, first let's look at the main types of cells in our blood and what they do. Just like the different parts of a car come together to make it run, all three of these cell types are very important in keeping our bodies healthy.

• Red blood cells (Erythrocytes): These are the cells that carry oxygen throughout our bodies. Just think, every tiny part of our body needs energy to function. The oxygen these red blood cells carry helps provide that energy.
• White blood cells (Leukocytes): These are like the body's security guards. When germs, such as bacteria, viruses, parasites, and fungi, enter the body, these white cells fight them and protect us from diseases. They are the main components of our immune system.
• Platelets (Thrombocytes): Have you ever wondered how a small cut can stop bleeding? These platelets help with that. When bleeding occurs, these platelets clump together to form a blood clot, stopping the bleeding. Otherwise, we can lose a large amount of blood even from a small cut.

So, are there different types of cytopenia?

Yes, of course. Cytopenia is not a single disease. It is classified according to what type of cells are lacking in your blood.

• Anemia: You've probably heard of this. It's a condition where there are fewer red blood cells. What happens then? The amount of oxygen that reaches the body decreases.
• Leukopenia: This is a decrease in the number of white blood cells. Remember, white cells are the ones that fight disease. So when they decrease, we are at an increased risk of getting sick. Another condition related to this is called neutropenia . This is a decrease in a special type of white blood cell called neutrophils. Neutrophils are the most abundant of our white blood cells.
• Thrombocytopenia: This is a decrease in the number of platelets, which help blood clot. When these are low, blood does not clot properly. Even a small bruise can cause large blood spots, or it can be difficult to stop bleeding.
• Pancytopenia: This is a more serious condition. This is when all three of the above mentioned red cells, white cells, and platelets decrease at once.

There is another classification, based on the cause of this cytopenia:

• Autoimmune Cytopenia:Sometimes our immune system goes haywire and starts attacking our own healthy blood cells. It's like throwing stones at our own house. When that happens, one or more blood cells can be lost.
• Refractory Cytopenia: This is the part of our bone marrow that makes blood cells. It is located inside some of the larger bones, like a sponge. So, this is the name given to the condition that occurs when this bone marrow does not make blood cells normally, that is, when the production of blood cells decreases.

What symptoms do we experience when these blood cells decrease?

Good question. Because not everyone has symptoms. Some people may not know anything, and it's only discovered by chance through a blood test. But if they do, the symptoms can vary depending on the type of cells that are reduced, how much they are reduced, and the underlying cause.

Let's see what characteristics may apply to each type:

Symptoms of low red blood cells (anemia):

• Feeling tired and lifeless all the time.
• Difficulty breathing (dyspnea) occurs when doing something strenuous, such as climbing a flight of stairs.
• An irregular or rapid heartbeat.
• The skin becomes pale and cold .
• Sometimes there may be chest pain .

Symptoms of low white blood cells (leukopenia/neutropenia):

• Just feeling tired .
• Fever and chills .
• Sore throat (Pharyngitis)
• Mouth sores .
• A severe cough .
• Diarrhea .
• Swollen lymph nodes .

Symptoms of low platelet count (thrombocytopenia):

• The fact that even a small bump can easily cause blood spots (bruises) to form on the body .
• Bleeding that doesn't stop when you get a wound, or bleeding that lasts a long time .
• Sometimes small red or purple dots (petechiae) appear on the skin. These are actually small hemorrhages under the skin.

Why are my blood cells decreasing like this? What are the causes of this?

There can be many reasons for this condition called cytopenia. Simply put, there can be two main reasons. One is that there is a problem with the production of blood cells from the bone marrow that I mentioned earlier. Or, after the blood cells are produced in the bone marrow and added to the blood, those cells are destroyed for some reason.

Some of these reasons may be inherited , that is, things that come from genes. Some may be acquired, which develops later .

Possible causes of anemia:

Anemia is often caused by nutritional deficiencies.Because. Especially iron deficiency `(Iron-deficiency Anemia)` . Nutrients such as iron, vitamin B12 `(Vitamin B12)`, and folate `(Folate)` are essential for our bone marrow to make healthy red blood cells. If these are not enough, red blood cells will decrease. In addition, anemia can also occur due to bleeding (due to injuries, surgeries, etc.) and diseases that destroy red blood cells.

• Autoimmune Diseases
• Blood disorders and Bone marrow disorders
• Cancer
• Genetic conditions
• G6PD deficiency
• Some medications
• Nutritional deficiencies
• Pregnancy
• Pyruvate kinase deficiency
• Sickle cell disease
• Thalassemia

Possible causes of Leukopenia/Neutropenia:

Cancer treatments, especially chemotherapy and radiation, are a major cause of low white blood cells. These treatments kill cancer cells, but as a side effect, some healthy cells (like blood cells) can also be destroyed.

• Autoimmune Diseases
• Blood and Bone Marrow Disorders
• Cancer
• Cancer treatments
• Genetic conditions
• Infections
• Some medications
• Nutritional deficiencies

Possible causes of thrombocytopenia:

• Alcohol use disorder
• Autoimmune diseases, for example , Immune Thrombocytopenia
• Blood and bone marrow disorders, such as Thrombotic Thrombocytopenic Purpura (TPP)
• Cancer
• Cancer treatments
• Genetic conditions
• Infections
• Certain medications, for example heparin-induced thrombocytopenia (HIT)
• Nutritional deficiencies
• Pregnancy
• Exposure to toxic chemicals

There are also types of cytopenias where the exact cause cannot be found:

Sometimes, doctors can't pinpoint the exact cause of these low blood cell counts. In such cases, these conditions fall into two categories:

• Clonal Cytopenia of Undetermined Significance (CCUS) is caused by:This is when several blood cells have the same inherited genetic mutation in their DNA. A person with CCUS is at increased risk of developing certain blood diseases and cardiovascular disease.
• Idiopathic Cytopenia of Undetermined Significance (ICUS): In this, no such genetic mutation is found in the DNA of the blood cells.

How do doctors diagnose this condition of cytopenia? What tests are performed?

This is usually found if you have symptoms, or when you have a blood test for some other reason. The main test is called a complete blood count (CBC) . This is a very common blood test. It gives your doctor a clear picture of how many red cells, white cells, and platelets you have, and whether there are any changes in the nature of those cells. It can also give clues about some diseases.

If the CBC shows low blood cell counts, the doctor will then try to figure out why the low count is so low. He or she may do further tests to determine that.

What additional tests are done to find the cause?

• Peripheral Blood Smear: This involves taking a small sample of your blood, placing it on a glass slide, and looking at it under a microscope. The shape and appearance of the cells can provide clues as to what is causing the problem.
• Bone Marrow Aspiration and Biopsy: This is a slightly more complicated test. In this test, a doctor takes a small sample of bone marrow and checks it for abnormal cells. This test is important for diagnosing serious diseases like cancer or other conditions that affect the blood and bone marrow.

In addition to this, various other lab tests can be performed to find the exact cause.

Okay, now what are the treatments for this condition of cytopenia?

The treatment depends on how severe your condition is, whether you have symptoms, and what the underlying cause is. In some mild cases, meaning there is no underlying cause and no symptoms, no treatment may be needed .

However, if treatment is needed, it is usually done to treat the underlying condition that caused the low blood cell count. For example, if it is due to a nutritional deficiency, your doctor may tell you to make changes to your diet or take nutritional supplements. If the low blood cell count is due to an infection, you may be given antibiotics .

In some severe cases, treatments that directly increase blood cell counts may be necessary. These include:

• Granulocyte Colony-Stimulating Factor (G-CSF):These are medications. They work by increasing your neutrophils, a type of white blood cell. G-CSF is often given to people undergoing chemotherapy to prevent neutropenia.
• Blood Transfusion: If your body cannot make its own blood cells, you may need to receive a blood transfusion from someone else.
• Bone Marrow or Stem Cell Transplant: This involves removing abnormal, immature blood cells from your bone marrow and replacing them with healthy cells. These cells will later become mature blood cells and return to your bloodstream.
• Splenectomy: This is a surgical procedure to remove your spleen . Sometimes the spleen can trap blood cells and remove them from the bloodstream. This surgery may be necessary in such cases.

Is there anything we can do to prevent this cytopenia from developing?

In fact, some causes, for example, autoimmune diseases, blood and bone marrow diseases, and cancer, are difficult for us to prevent. They are things that happen beyond our control.

However, we can reduce the risk of developing some types of cytopenias by ensuring that our bodies get the nutrients they need to make healthy red blood cells. For example, getting enough iron in your diet can help prevent iron-deficiency anemia .

It is also important to limit alcohol consumption , as alcohol can interfere with the body's ability to absorb nutrients. This can also lead to a decrease in blood cells. Once alcohol consumption is stopped, these blood abnormalities can largely return to normal.

So, what is the prognosis for recovery from this condition? (Prognosis)

Your prognosis, or outlook, depends entirely on the cause of your low blood cell count. For example, if anemia is caused by a nutritional deficiency, it can be completely cured if treated properly and with the right diet. If your white blood cell count is low due to a bacteria or virus, treating the infection can help your white blood cell count return to normal.

However, if cytopenia is caused by a genetic condition, blood or bone marrow disease, or cancer, it may require more complex treatment . Your doctor may need to monitor your blood cell counts and do regular tests to make sure you are staying healthy.

Therefore, it is best to ask your doctor what the recovery prospects are for your condition.

What are the important questions to ask your doctor?

When you find out that you have this condition, it's normal to have a lot of questions. Don't be afraid. Ask your doctor about these things clearly:

• "What type of cytopenia do I have?"
• "What is causing my low blood cell count?"
• "What treatment options do I have?"
• "What are the side effects of these treatments?"
• "How long will it take for my blood cell count to return to normal?"
• "How long will I have to receive treatment? How often do I need to come for tests?"
• "Can my condition be completely cured?"

Is cytopenia really anemia?

This is also a place where many people get confused. Anemia is just one type of condition under the umbrella term cytopenia . Anemia is a decrease in the number of red blood cells (erythrocytes). It can also be caused by a decrease in the protein hemoglobin in red blood cells. This hemoglobin is what helps carry oxygen.

Cytopenia is a general term for a decrease in one or more blood cells . It includes anemia (decrease in red blood cells), leukopenia (decrease in white blood cells), neutropenia (decrease in neutrophils), thrombocytopenia (decrease in platelets), and pancytopenia (decrease in all of these cells).

So, if you find out that you have low levels of one or more of your blood cells, talk to your doctor before you panic. Depending on the cause, you may or may not need treatment. Your doctor is the best person to advise you on this.

Finally, some important things you need to remember

Okay, we've talked a lot about cytopenia now. Here are some key things to remember:

• Cytopenia is a decrease in the number of one or more of the red cells, white cells, or platelets in your blood.
• There can be many reasons for this; from nutritional deficiencies, to infections, genetic conditions, cancer, and even certain medications.
• Symptoms don't come to everyone the same way . Some people may not have any symptoms at all. Fatigue, frequent illness, and easy bruising are common.
• A simple blood test (CBC) can detect this. Then, further tests can be done to find the cause.
• Treatment depends on the cause and severity of the condition. Sometimes no treatment is needed, sometimes the underlying cause is treated, and in severe cases, there are special treatments that increase blood cell counts.
• Some types of cytopenias can be prevented , especially by eating a balanced diet and limiting alcohol consumption.
• If you have any doubts or questions about this, definitely talk to your doctor . Don't be afraid or make decisions on your own.

Remember, the most important thing is to be aware of these conditions so that we can seek medical advice quickly and live a healthy life.
