What is Evans Syndrome? Let's talk about it!

Do you sometimes feel tired? Or do you have a hard time stopping bleeding even from the smallest things? Maybe it's because your body's immune system is working against you. Today we are going to talk about such a rare but very important condition to know about. That is Evans Syndrome . Don't worry, we will talk about everything in simple terms.

So, what is Evans Syndrome?

Simply put, Evans Syndrome is an autoimmune disease . What happens is that the soldiers who are supposed to protect our body, the immune system, mistakenly start destroying some of our own blood cells. It's like our own army attacking our own people. As a result, our body loses the necessary amount of blood cells. This abnormal decrease in blood cells is what we call cytopenia in medicine.

Most people with Evans Syndrome are first affected by low red blood cells (a condition called anemia ) and platelets (a condition called thrombocytopenia ). In addition to both, some people may also have low numbers of a type of white blood cell called neutrophils (a condition called neutropenia ).

When these blood cell types are low, many important things in our body, such as getting oxygen, clotting, and fighting disease, are affected. That's why we feel weak, tired, start to bleed easily, and get sick more often .

This condition can affect some people very mildly, while others can be quite severe. And its effects do not last the same way throughout life. The best thing is that although there is no cure for it, treatment can help control the symptoms and minimize the effects .

What are the symptoms of Evans Syndrome?

The symptoms of Evans Syndrome can vary greatly. It depends on what type of cytopenia you have and how severe it is. Often, anemia or thrombocytopenia occurs first, and the others appear later.

Early symptoms of red blood cell deficiency ( anemia ):

Are you tired even after walking for a short distance? Are you feeling tired and unable to do the things you used to? Maybe your face is looking a little pale. These are some of the early signs of anemia :

• Just feeling extremely tired .
• Pale skin (pallor) .
• Lightheadedness or dizziness .
• Difficulty breathing (dyspnea) .
• Fast heartbeat (tachycardia) .
• Feeling or feeling like your heart is beating abnormally (heart palpitations) .

Early symptoms of platelet deficiency (thrombocytopenia):

Have you noticed that sometimes small red dots appear on your skin? Or do you just get bruises all over your body? Do you feel like your gums are bleeding more than usual when you brush your teeth? These are the possible symptoms of low platelets:

• Tiny red bleeding spots (petechiae) under the skin.
• Purple spots on the skin (purpura) .
• Bruising (ecchymosis) that occurs without a cause.
• Excessive bleeding from the gums or nose.
• Heavy bleeding during menstruation in women.
• Bleeding with stool or urine.

Symptoms of neutropenia (these may or may not occur later):

It's normal to get a cold or two a month. But do you often get sick with a fever? Do you get mouth sores all the time? Do they seem to take a long time to heal? Here are some things that can happen when your neutrophils are low:

• Fever.
• Mouth ulcers .
• Frequent colds, fever, and stomach aches.
• Recurrent ear infections.
• Long-term fungal infections.
• Urinary tract infections (UTIs) .

Other symptoms of Evans Syndrome (these may occur occasionally):

• Swollen lymph nodes in the neck.
• Enlarged spleen .
• Enlarged liver .
• Jaundice .

Why does Evans Syndrome occur?

As we mentioned earlier, Evans Syndrome is an autoimmune disease . This means that our body's immune system mistakenly recognizes some of our own blood cells as "enemy" and begins to attack them.

This work is done by B cells, a special type of cell in our immune system. These B cells make something called antibodies . These antibodies go and catch those innocent blood cells and destroy them. Usually, they start attacking one type of blood cell first, and then they can start attacking other types of blood cells.

This process is what ultimately causes you to have a deficiency in at least two types of blood cells (cytopenia), and sometimes all three. A deficiency in all three is called pancytopenia . The three main conditions in which these blood cells are low are:

• Autoimmune hemolytic anemia (AIHA): This is when red blood cells are reduced. That is, they are destroyed faster than the body can make them.
• Immune thrombocytopenia (ITP) : This is a condition in which there is a decrease in platelets. The immune system attacks and removes platelets from the bloodstream.
• Autoimmune neutropenia (AIN) : This is a condition in which the number of neutrophils, a type of white blood cell, decreases. The immune system attacks and destroys the neutrophils.

Think about it, there can be many reasons for low blood cell counts (cytopenia). Sometimes it can be because the bone marrow isn't making enough blood cells. However, in autoimmune cytopenia, the immune system destroys its own blood cells.

What are the triggers for Evans Syndrome?

Scientists still don't know exactly why these autoimmune diseases develop. But they have observed that these diseases often start after a serious illness or an event that puts a lot of stress on the immune system. These are called triggers .

Also, if you have one autoimmune disease, you are statistically more likely to develop another. It's as if this immune system disorder spreads from one part of the body to another.

Evans syndrome can occur on its own (this is called primary Evans syndrome ), or it can occur as a secondary condition associated with another condition (this is called secondary Evans syndrome) . Some of the conditions that can be associated in this way are:

• Systemic lupus erythematosus (lupus)
• Common variable immunodeficiency
• Selective IgA deficiency
• Sjögren's syndrome
• Non-Hodgkin lymphoma
• Chronic lymphocytic leukemia
• Chronic hepatitis C
• Chronic HIV infection

If you have primary Evans syndrome, it may have developed after a temporary illness, or you may not have a clear trigger. Scientists classify Evans syndrome as an idiopathic condition. This means that no direct cause has been found.

What are the possible complications of Evans Syndrome?

Not everyone with Evans Syndrome will develop complications. Some people only have very mild symptoms. However, in severe cases, these blood cell deficiencies (cytopenias) can be life-threatening. For example:

• When there are not enough red blood cells to carry oxygen to the body, there is not enough oxygen in the blood (hypoxemia) . This is very hard on the heart and can lead to heart disease and heart failure.
• When you don't have enough platelets , which help your blood clot, your blood doesn't clot properly. This can cause you to bleed easily and quickly. This can quickly lead to severe anemia.
• When your body loses neutrophils , which help fight infection, you are more likely to get infections more often, and they can become severe and spread throughout your body. This can lead to a dangerous condition called sepsis .

How do doctors diagnose Evans Syndrome?

Evans Syndrome is diagnosed through blood tests . It may be detected if you develop symptoms of cytopenia, or during a blood cell count performed during a routine health check.

If your Complete Blood Count (CBC) shows that you have low red blood cells, platelets, or neutrophils, your medical team will do more tests. For example, they will check your blood for elevated levels of antibodies associated with Evans Syndrome. They will also check for other conditions that can cause cytopenia, such as certain infections or cancer.

Doctors confirm Evans Syndrome by ruling out all other causes. Sometimes, they may also need to do a CT scan (computed tomography scan) or a bone marrow biopsy to rule out other conditions.

Is there a complete cure for Evans Syndrome? How is it treated?

In fact, there is no complete cure for Evans Syndrome, or any other autoimmune disease. Doctors treat these autoimmune diseases by giving you medications that reduce the activity of your immune system.

Additionally, your symptoms may be treated separately. For example, if your blood cell count is very low, your doctor may be able to correct this with occasional blood transfusions .

Like many long-term autoimmune diseases, Evans Syndrome can get better and worse over time. Sometimes symptoms may seem to go away (called remission) , but then they may come back or get worse (called relapse ).

You may need to try different treatments throughout your life, as their success can vary over time. Your doctor will try to protect you from the most serious complications of Evans Syndrome.

What are the treatments?

The standard treatment for Evans Syndrome is immunosuppressant medications and, if necessary, blood transfusions. These immunosuppressants work by reducing the mistaken attack by your immune system.

Main types of medications given:

• Corticosteroids , such as prednisone . This is usually the first treatment given.
• Intravenous immunoglobulin therapy (IVIg) involves giving a solution containing human antibodies through a vein. These new antibodies can bind to the faulty autoimmune antibodies and disable them.

If you don't respond well to standard treatments, your doctor may try other treatments. These include:

• Monoclonal antibodies , such as rituximab . These are antibodies made in a lab. Sometimes these can stop the autoimmune response. Your doctor may suggest these if other medications don't work.
• Splenectomy . In severe cases, your doctor may recommend surgery to remove your spleen. Your spleen is where old blood cells are removed. So when the spleen is removed, the process slows down a bit.

Are there any complications or side effects of the treatment?

When you take immunosuppressants, your immune system's response to your autoimmune disease is reduced. However, your immunity to infections is also reduced . So you'll need to take special precautions to avoid getting sick.

Your doctor may recommend additional vaccines in addition to the ones you've already received. When your immune system is weakened (immunocompromised), you may be more susceptible to illnesses that you wouldn't normally get.

Does living with Evans Syndrome affect lifespan?

Evans Syndrome does not necessarily affect your lifespan. Some people only have very mild, occasional symptoms. However, some complications, such as bleeding, heart disease, and infection, can be life-threatening.

If you have secondary Evans syndrome, meaning you have it with another chronic condition, that can also affect your lifespan. You may have life-threatening complications that come with your other condition.

What is the outlook for someone with Evans Syndrome?

The experiences of people with Evans Syndrome vary greatly. Symptoms can be mild or severe. Some people feel like their symptoms go away completely (remission). Others experience them again later (relapse).

Many people need some form of treatment and regular medical check-ups. Treatments often work well, but not always. Sometimes, the effectiveness of treatments may seem to decrease over time. You may need to try other treatments.

How do I take care of myself while living with Evans Syndrome?

If you have Evans Syndrome, it's important to keep up with your regular medical checkups . Even if you feel well, your doctor will want to monitor your condition and catch it early if it gets worse.

Also, you should always pay attention to yourself and watch for any new symptoms. If you have a cold that doesn't get better, or if you have uncontrollable bleeding, call your doctor right away .

What questions should I ask my doctor?

You might want to ask your doctor questions like these:

• What types of blood cells am I lacking?
• How much have they decreased?
• What symptoms or warning signs should I look out for?
• How do I know if the treatment is working or not?
• What happens if the treatment doesn't work?
• When should I book my next doctor's appointment?

Evans Syndrome is a rare condition that you may not have heard of before. The symptoms can be strange and disturbing. Understanding what is going on and what it means can be a bit of a daunting process.

Although Evans Syndrome is a lifelong condition, it is not always the same. Keep the hope that you will feel better, at least sometimes. No matter how you feel, your medical team will be there to provide you with the care you need.
