Is there a problem with your blood? Let's learn about hemoglobinopathy in simple terms!

Do you always feel tired and lethargic? Maybe your skin is a little pale? Or has anyone in your family had a blood disease? Then what I am going to tell you is very important for you. Today we are going to talk about a blood disease called Hemoglobinopathy, which has a somewhat complicated name, but is seen in many people. Don't worry, we will talk about this very simply.

What is Hemoglobinopathy? Let's find out exactly!

Simply put, hemoglobinopathies are a group of inherited diseases that affect the protein in our blood called hemoglobin. Now you're probably wondering what this hemoglobin is, right?

Think of it this way: hemoglobin is like a little hero inside our red blood cells. It's the one that picks up oxygen from our lungs when we breathe and distributes it throughout our bodies. It acts like an oxygen taxi. So if this hemoglobin isn't produced properly, or if it's not produced enough, our bodies don't get enough oxygen. That's when the problems start.

This condition is inherited, meaning it is caused by a change in the genes we inherit from our parents. Millions of people around the world suffer from this condition. In fact, it is the most common type of inherited blood disorder. Researchers have identified more than 600 types of hemoglobinopathies!

When our bodies produce abnormal hemoglobin, or not enough of it, symptoms such as body aches, fatigue, and damage to various organs can occur. That's why it's so important to recognize it early. That's why doctors test babies for hemoglobinopathy as soon as they're born.

The important thing is that Hemoglobinopathy is not a completely curable disease. However, with proper treatment, we can control the symptoms and prevent complications.

What types of hemoglobinopathies are there?

As we mentioned earlier, there are hundreds of types of this. These types are often named using English letters. The letters refer to the different variants of the hemoglobin protein and the order in which researchers discovered them. This helps doctors understand the exact genetic variation involved.

Here are some of the most common types of hemoglobinopathy:

• Hemoglobin C disease: This is where normal hemoglobin is replaced by a type called hemoglobin C.
• Hemoglobin E disease: Here, normal hemoglobin is replaced by hemoglobin E.
• Hemoglobin D disease: Here, normal hemoglobin is replaced by hemoglobin D.
• Hemoglobin SC disease: This condition occurs if you inherit one sickle cell gene and one hemoglobin C gene.
• Hemoglobin SD disease: Here, one sickle cell gene and one hemoglobin D gene are inherited.
• Hemoglobin SE disease: Here, one sickle cell gene and one hemoglobin E gene are inherited.
• Sickle cell disease: In this condition, your red blood cells become sickle-shaped. This prevents them from moving easily through the blood vessels and can cause them to become blocked.
• Thalassemias: In this condition, your body does not produce enough hemoglobin.

This may sound a little complicated, but a doctor can explain it to you further.

What are the symptoms of this? See if you have these too...

The symptoms of hemoglobinopathy can vary from person to person, but there are some common symptoms:

• Cold hands and feet
• Dark urine (darkening)
• Frequent fatigue
• Delayed development in children
• Yellowing of the skin and eyes (Jaundice)
• Pale skin
• Difficulty breathing, wheezing
• Sleeping more than usual
• Swelling of the limbs

Babies with severe hemoglobinopathy may show symptoms at birth. Sometimes, symptoms appear during childhood. In adults, these symptoms may become more severe during periods of exacerbation of the disease (such as a sickle cell crisis).

Why does this hemoglobinopathy occur?

The main reason for this is that there is a gene variation that affects your hemoglobin. You can get this genetic variation from your mother, your father, or both. This means that this is not something we can control, it is something that comes from inheritance.

Who is more likely to develop this? (Risk factors)

Some people are more likely to develop this hemoglobinopathy. Let's take a look at who they are:

• If your ancestry is of African, Mediterranean, Southeast Asian, or West Asian origin. (These conditions can also be seen in Sri Lanka)
• If your mother, father, or sibling has hemoglobinopathy.
• If you live in an area where newborn screening for hemoglobinopathy is not routinely done.

If you have hemoglobinopathy, there is a chance that your child will also have the disease. Therefore, it is very important to seek medical advice before starting a family.

What complications can this cause?

If hemoglobinopathy is not properly controlled, various complications can occur. Some of them are:

• Anemia: Some types of hemoglobinopathy can cause anemia, which can lead to a decrease in red blood cells. This can lead to increased fatigue and weakness.
• Frequent infections: Hemoglobinopathy can lead to a compromised immune system , which increases the risk of illness and infection.
• Organ damage: Hemoglobinopathy causes a decrease in oxygen levels in the blood. When oxygen-rich blood is not properly delivered over a period of time, our tissues and organs can be damaged.
• Pain episodes: In some types of hemoglobinopathies, such as sickle cell disease, blood clots can form inside blood vessels and block them. This can lead to severe pain and reduced blood flow.

How do you accurately diagnose this disease? (Diagnosis)

Doctors perform several tests to determine exactly whether you have hemoglobinopathy.

• Complete blood count (CBC): This is usually the first blood test done. It can tell you about the types of cells in your blood, that is, how many of each type of cell you have.
• Genetic testing: This test can identify exactly what genetic changes are involved.
• Hemoglobin electrophoresis: This test separates hemoglobin molecules from a sample of your blood and looks for abnormalities.
• Iron studies: This test can be done to find out if you have iron-deficiency anemia.
• Newborn screening: In many countries like Canada and America, newborn babies are screened for hemoglobinopathy. Some hospitals in Sri Lanka also have this facility.
• Prenatal testing: This test can be used to determine whether the fetus has hemoglobinopathy during pregnancy.

What are the treatments?

There are several treatments for hemoglobinopathy, but these treatments vary depending on the type and severity of the disease.

• Blood transfusions: Some conditions, such as thalassemia and sickle cell disease, affect the amount of hemoglobin in the blood. Blood transfusions may be necessary to maintain normal hemoglobin levels.
• Folic acid tablets: These can help increase red blood cell production.
• Gene therapy: This is a relatively new treatment. Scientists take affected cells from your body, modify them in special ways, and then reintroduce them back into your body. It's like rewriting the instructions in your genes.
• Iron chelation therapy: If you have too much iron in your body, this treatment can remove the excess iron. This medication is given either by mouth or as an injection.
• Oxygen therapy: Your doctor may recommend oxygen therapy along with other treatments. The goal of this is to increase the oxygen levels in your blood and reduce pain.
• Stem cell transplant: This involves replacing abnormal red blood cells with healthy red blood cells. However, this is not very common, as it is difficult to find a suitable donor. It also carries the risk of graft-versus-host disease (GvHD) .

Remember, depending on the type of hemoglobinopathy you have, you may not need any treatment at all. So it's best to talk to your doctor and ask what's best for you.

How soon will I feel better after treatment?

It really depends on the type of hemoglobinopathy you have and its severity. Most people start to feel better within a few weeks or months of starting treatment.

Hemoglobinopathy is a lifelong condition, so you will need regular medical tests and monitoring. Your doctor will help you manage your symptoms.

What does the future hold for those living with this disease?

With proper treatment, your future can be bright. More than 90% of people with hemoglobinopathy survive to adulthood.

However, if left untreated, many types of hemoglobinopathies can lead to death within the first few years of life. Therefore, early diagnosis and treatment are the best way to prevent serious complications.

Can't this be prevented?

Unfortunately, no. Since hemoglobinopathy is something you inherit, there is no way to prevent it. However, we can manage the symptoms with proper treatment.

How do I take care of myself?

Living with hemoglobinopathy can be challenging, but if you take good care of yourself, you can reduce the risk of pain and other side effects.

Here are some general tips that may help you:

• Drink plenty of water. Try to drink at least 2-3 liters of water a day.
• Be physically active, but don't overdo it. Listen to your body. If you feel tired, rest.
• Eat foods rich in iron, vitamins, and minerals. Include greens, fruits, vegetables, meat, and fish in your diet.
• Manage your stress. Use meditation, yoga, or other mindfulness techniques that you enjoy.
• Wash your hands often. This helps protect you from infections.

When should I see a doctor?

If you have symptoms like extreme fatigue, difficulty breathing, or pale skin, be sure to see a doctor and tell them about it.

If you have already been diagnosed with hemoglobinopathy, see your doctor immediately if your symptoms return or get worse. He or she can adjust your treatment.

What questions should you ask the doctor?

If you or your child has hemoglobinopathy, it's a good idea to ask your doctor these questions:

• What type of hemoglobinopathy do I/my child have?
• What kind of treatment do you recommend?
• Will I need to see other specialists for treatment?
• Do I need to change my diet or exercise habits?
• What is the likelihood that my children will have this condition?
• Do you have any more information about this? (e.g. books, websites)

When do you need to go to the Emergency Treatment Unit (ETU) ?

If you have any of the following symptoms, call 911 (1990 in Sri Lanka) or go to the nearest emergency room immediately:

• Chest pain
• Dizziness
• Fever higher than 103 degrees Fahrenheit (39.4 degrees Celsius)
• Severe pain that does not subside despite taking medication
• Symptoms of a stroke, for example, sudden loss of consciousness, difficulty speaking.

How does hemoglobinopathy affect my A1C?

Hemoglobinopathy can cause your A1C test results to be inaccurate. Depending on your genetic variant, it may show a lower or higher value than you actually have.

If you have hemoglobinopathy, your doctor may recommend a test that can help minimize this problem. This A1C is very important for people with diabetes, so don't forget to talk to your doctor about this as well.

Finally, the most important things to remember!

It's normal to feel scared and anxious when you learn that you or your child has a lifelong blood disorder. Questions like "How will hemoglobinopathy affect my life?", "Will I be in constant pain?", "How will this disease affect my child?" may arise in your mind.

But the good news is that with proper treatment and symptom control, you can live as healthy as possible. The best thing you can do is talk to your doctor. Don't delay. Early diagnosis and treatment are the keys to a long, healthy life.

Don't worry, you are not alone. Doctors, nurses, and your family will help you on this journey. Be brave!
