Do you sometimes feel tired and lethargic for no reason? Or has a doctor ever looked at your blood test report and said something like, "There's a slight change in the shape of your red blood cells?" At such times, one of the words we hear is `(Poikilocytosis)` (pronounced: poi-ki-lo-say-to-sis). Don't be too scared when you hear this name. This is not a disease, but it can be a sign that something else is going on inside our body. So, it's very important to be aware of this.
What exactly is `(Poikilocytosis)`?
Simply put, ``Poikilocytosis`` means that a significant number (that is, more than 10%) of the red blood cells in our blood are of unusual shapes. Now you may be thinking, "So why does the shape of red blood cells matter?"
Just think, every other cell, tissue, and organ in our body needs energy to live and work. That energy is provided by oxygen. Who knows, this oxygen, like bringing a gas cylinder home, is carried throughout the body? That's our red blood cells. Normally, if you take a healthy red blood cell, they are all the same size and shape. Like a round coin (like a disk) that is slightly concave on both sides.
So, if the shape of these red blood cells changes (`(Poikilocytosis)`) or the size changes (there is another one called `(Anisocytosis)`), they cannot carry oxygen properly. That is when we get conditions like anemia (lack of blood in the blood). That means the cells of the body do not get enough oxygen, which means energy.
What are the abnormal shapes of red blood cells? (Poikilocytes)
Doctors classify these abnormally shaped red blood cells (also called `Poikilocytes`) by their appearance. If you have `(Poikilocytosis)` in a blood sample, you may see one or more of the following:
- Acanthocytes / Spur cells : These are like a thorn branch. They have long, wide, spike-like protrusions protruding from the cell membrane.
- Codocytes / Target cells : These look like a target board. There is a dark circle in the middle.
- Dacrocytes / Teardrop cells : Teardrop-shaped. One side of the cell is thin and pointed.
- Drepanocytes / Sickle cells : These are thin, sickle-shaped cells that can be seen in people with sickle cell disease.
- Echinocytes : Like a sea urchin, the cell is covered with spines at equal distances throughout.
- Elliptocytes / Ovalocytes or Cigar cells : These are oval-shaped and unusually long. They can range in size from egg-shaped to cigar-shaped.
- Schistocytes : These are fragments of red blood cells. They often have a rough, broken appearance, but can be any shape.
- Spherocytes : Spherical. Like a small ball.
Each of these types can be associated with specific medical conditions.
What are the symptoms of this condition?
The symptoms of ``Poikilocytosis`` vary depending on the cause, but they are often the same as those seen in anemia.
Here are some symptoms of anemia:
- Weakness or extreme fatigue (just feeling tired).
- Difficulty breathing (dyspnea) – shortness of breath even with small tasks.
- Fast or irregular heartbeat (arrhythmia).
- Sometimes you hear a "whooshing" sound in your ears (pulsatile tinnitus).
- Headache .
- Dizziness .
- Pale skin .
- Chest pain .
If you have one or more of these symptoms, it is best to seek medical advice.
Why is this happening? What are the reasons?
The causes of these abnormal red blood cell shapes can be divided into two main categories: inherited and acquired . Some conditions, such as Myelodysplastic Syndrome, can cause both.
Inherited Conditions
In most cases, congenital causes are caused by an error in the genetic information (DNA) that a red blood cell needs to grow, function, and survive properly. Red blood cells with such abnormal structures break down quickly before the body can make new cells. This is called hemolytic anemia .
Some congenital conditions that cause `(Poikilocytosis)`:
- `(Hereditary Elliptocytosis)`
- `(Hereditary Spherocytosis)`
- `(McLeod Syndrome)`
- `(Pyruvate Kinase Deficiency)`
- `(Sickle Cell Disease)` (Sickle Cell Disease)
- `(Thalassemia)`
These are often things that are passed down through generations.
Acquired Conditions
Over time, certain medical conditions can also cause the shape of red blood cells to change. For example, if the body doesn't get enough of the nutrients it needs to make healthy red blood cells, such as vitamin B12, folate, and iron, various anemias can occur. Poikilocytosis is a common sign of these nutritional deficiencies. It can also be caused by diseases, such as some cancers, that interfere with red blood cell production.
Some of the later conditions that cause `(Poikilocytosis)` are:
- Autoimmune Hemolytic Anemia
- Burns (if extensive)
- `(Celiac Disease)`
- Various infections
- Iron-deficiency anemia
- Kidney Disease
- Leukemia (blood cancer)
- Liver Disease
- Megaloblastic anemia (due to vitamin B12 or folate deficiency)
- `(Myelofibrosis)`
- Poisoning (e.g. lead)
- Reaction to a blood transfusion
- Reaction to a splenectomy
- Snakebite
What complications can this cause?
Many conditions that cause poikilocytosis can be managed with treatment, and some can be cured completely. However, if left untreated, some conditions can become serious and even life-threatening. For example, if you have anemia, you may feel so tired that you can't do your daily activities. If you lose enough healthy red blood cells over time, it can lead to conditions like organ failure .
Especially in young children, if untreated anemia occurs, it can affect their growth and development.
Therefore, once your doctor has determined the exact cause of your Poikilocytosis, he or she will provide the necessary treatment to prevent complications like these.
How do you diagnose this exactly? (Diagnosis)
The main test a doctor can use to diagnose poikilocytosis is a peripheral blood smear (PBS) . This involves a lab technician taking a drop of your blood sample and looking at it under a microscope. They can then see how many of your red blood cells are oddly shaped and what kind of shape they are.
Some cell types are more common in specific disease conditions. However, even within the same disease condition, there can be different types of cells. For example, in conditions like `(Hemolytic Anemia)`, `(Megaloblastic Anemia)`, `(Myelofibrosis)`, `(Thalassemia)`, several abnormal cell types can be seen.
Your doctors may need to do some more tests to find out exactly what is causing your poikilocytosis.
Additional tests to find the cause of `(Poikilocytosis)`
A complete blood count (CBC) is often performed along with a PBS. The CBC can provide a lot of information about the cells in your blood, including their levels and sizes. Some of the values in the CBC can provide more information about the red blood cells, which can help determine the cause of Poikilocytosis. These values include:
- `Mean Corpuscular Volume (MCV)` : The average size of your red blood cells.
- `Mean Corpuscular Hemoglobin (MCH)` : The average amount of hemoglobin in your red blood cells.
- `Mean Corpuscular Hemoglobin Concentration (MCHC)` : The average concentration of hemoglobin in your red blood cells.
- `Red Cell Distribution Width (RDW)` : How varied your red blood cells are in size.
Additionally, your doctor may check your vitamin B12, folate, and iron levels, and may also order liver function tests.
What are the treatments for this?
Treatment depends on the cause of your poikilocytosis and how severe your symptoms are.
Remember, if the cause of this condition is a nutritional deficiency (e.g. iron, vitamin B12 deficiency), taking the relevant nutritional supplements, or switching to a diet rich in vitamin B12 or folate, can often resolve this `(Poikilocytosis)` condition.
Many congenital conditions require careful monitoring . You may need regular blood transfusions to make sure you have enough healthy red blood cells. Or you may only need treatment based on whether you have symptoms.
Can this situation be prevented?
We cannot prevent congenital causes of ``Poikilocytosis.`` However, we can reduce the risk of some later-onset causes.
One of the best ways to take care of your red blood cells is to get the nutrients your body needs to produce them. Make sure you get enough B vitamins, folate, and iron . These are key ingredients your body needs to make healthy red blood cells. It also helps to limit the amount of alcohol you drink . Too much alcohol can make it harder for your body to absorb these nutrients.
What will the future hold? (Outlook)
In general, if the cause of `(Poikilocytosis)` is a later-onset condition, the prognosis is usually good. In cases of congenital causes, the prognosis varies depending on the underlying condition. For example, although the life expectancy of people with `(Sickle Cell Disease)` is generally considered to be short, new treatments have now made it possible to live for over 50 years while controlling symptoms.
When should you see a doctor?
If you have symptoms of anemia (things we talked about earlier, like fatigue and weakness), definitely see a doctor.
Even if you feel healthy and have no symptoms, it is important to have annual check-ups. Your doctor can also check your blood cells. A simple blood test, such as a complete blood count (CBC), can help detect and treat health problems before they become serious.
Is this ``Poikilocytosis'' a serious condition?
Poikilocytosis itself is not serious. However, it can be a sign of an underlying condition that can lead to complications if left untreated. Therefore, it is important to understand exactly what is causing Poikilocytosis and seek treatment if necessary.
Poikilocytosis may sound like a serious condition, but it's not. It's just a characteristic of your red blood cells that doctors use to assess your health. If you find out that your red blood cells are abnormal, don't hesitate to ask your doctor about it. He or she can tell you if it's affecting your health and, if so, what you can do to either eliminate the condition or manage the underlying condition.
The most important things we need to remember (Take-Home Message)
Okay, so, the main points to remember from what we've talked about are these:
- Poikilocytosis is when more than 10% of your red blood cells are abnormally shaped.
- This is not a disease, but it may be a sign of an underlying condition.
- Symptoms of anemia (fatigue, weakness, paleness) can also be seen in this case.
- The causes may be congenital or acquired (nutritional deficiencies, certain diseases).
- This can be detected with a simple blood test (`PBS`, `CBC`).
- Treatment depends on the cause, but it can often be managed.
- Maintaining a healthy diet can help prevent some of the causes of later onset.
- If you have symptoms or are in any doubt about this, it is best to see a doctor for advice.
So, I hope this information is useful to you. Stay healthy!
