What is Pancytopenia? Let's talk about it simply!

Do you sometimes feel so tired that you can't bear to do even the slightest thing? Or do you get blue bruises on your body without hitting anything? Perhaps you feel like you're getting sick more often, like a cold or flu? One reason behind this could be a decrease in all three major types of blood cells. In medicine, we call this condition pancytopenia . Don't worry, this is not a disease, but a symptom of another underlying condition. Let's understand this exactly.

Types of cells in our blood and their functions

To understand this, we first need to know about the three main soldiers in our blood. These blood cells are produced in the bone marrow, a spongy part of our bones.

Red Blood Cells

These are the cells that carry oxygen throughout our bodies. When we breathe, these red blood cells capture the oxygen that comes into our lungs and distribute it to every cell in our body. They also help carry carbon dioxide produced in the cells back to the lungs and out. These cells are what give our blood its red color.

White Blood Cells

These are the army of our body. Like soldiers defending the country. These white blood cells protect us from diseases by searching for, attacking, and destroying external enemies like viruses and bacteria that enter our bodies.

Platelets

These are the smallest cells in our blood. They're like little plasters on our bodies. When we get hurt somewhere and start bleeding, these platelets are the ones that rush in and stick together to seal the wound and stop the bleeding. We also call this blood clotting.

What are the symptoms of pancytopenia?

The symptoms of pancytopenia are actually the symptoms caused by the decrease in the three types of cells mentioned above. Sometimes, there may be no symptoms at all. Let's see what symptoms can occur under each of these conditions.

What are the causes of pancytopenia?

There can be many causes of pancytopenia. Sometimes, even after all the tests are done, there are cases where no cause can be found . We call this `Idiopathic Pancytopenia`. But here are some of the most common causes:

• Bone marrow diseases: Conditions in which the bone marrow is unable to produce enough healthy blood cells. For example, a disease called `Aplastic Anemia`.
• Cancer: Cancers of the blood or bone marrow, such as leukemia and lymphoma, spread to the bone marrow and interfere with the production of healthy cells. Many people think that pancytopenia is leukemia. No, it is not. But leukemia is the main cause of pancytopenia.
• Cancer treatments: Chemotherapy and radiation can destroy not only cancer cells, but also healthy blood cells that divide rapidly.
• Viral infections: This condition can be caused by some severe viral infections, such as HIV, Hepatitis C, and Mononucleosis.
• Autoimmune Disorders: Sometimes our body's own defense system mistakenly starts attacking our own healthy blood cells. Lupus is a good example of this.
• Certain medications: Although rare, this condition can occur as a side effect of medications such as some antibiotics and high blood pressure medications. Never stop taking any medication without consulting your doctor.
• Exposure to toxins: Exposure to chemicals like arsenic, benzene, or radiation can damage the bone marrow.
• Liver disease and excessive alcohol consumption: Diseases such as cirrhosis of the liver can cause the spleen to enlarge and blood cells to become trapped and destroyed.
• Nutritional deficiencies: In some countries, a lack of nutrients such as vitamin B12 or folate is also a cause of this condition.

How to diagnose this condition?

When you see a doctor, he or she will first ask you about your symptoms, ask about your family history of illnesses, and examine you. If pancytopenia is suspected, he or she may order several tests, such as:

• Complete Blood Count (FBC): This can check exactly how many red cells, white cells, and platelets are in your blood.
• Peripheral Blood Smear: A blood sample is examined under a microscope to see if the shape and appearance of the cells are abnormal.
• Bone Marrow Biopsy: This is the most definitive test. A very small piece of bone marrow is taken from a place such as the hip bone under anesthesia and examined to see if there is any disease in the bone marrow.
• Other tests: In addition, tests such as vitamin levels, liver function, and tests for infections may be done to find the cause.

How is pancytopenia treated?

The most important thing to remember is this: Treatment for pancytopenia depends on the underlying condition that caused it. Doctors will first try to find the cause and treat it.

• If the cause is a nutritional deficiency , it can be corrected with a proper diet and vitamin supplements.
• If the cause is a medication , the doctor will stop that medication and prescribe another appropriate medication.
• If it is due to an infection , that infection is treated.
• If the cause is an autoimmune disease , medications that suppress the immune system are given.

While treating the underlying cause, treatments such as these are also used to manage pancytopenia:

• Blood Transfusions: If the red blood cell or platelet count is very low, blood is given from outside sources to quickly restore it.
• Bone marrow stimulating drugs: Injections are given to help the bone marrow produce more blood cells.
• Stem Cell or Bone Marrow Transplant: In some severe cases, the diseased bone marrow is removed and replaced with healthy bone marrow.
