Does your blood clot easily? Let's learn about Antithrombin Deficiency!

Even if there is a small wound on our body, the bleeding stops after a while and the blood clots, right? It is really an amazing mechanism for our body to protect itself. However, if this blood clotting increases more than necessary, or if blood clots form inside the body for no reason? Then it can be a problem. Today we are going to talk about a special reason that causes blood to clot unnecessarily. That is Antithrombin Deficiency , some also call it Antithrombin III Deficiency.

What exactly is Antithrombin Deficiency?

Simply put, antithrombin deficiency is a condition related to our blood clotting process. In this, there is either a decrease in the protein called antithrombin, an important substance in our body that prevents excessive blood clotting, or it does not work properly.

Think of it this way. You're filling a bathtub with water. Someone has to turn off the faucet before it overflows, or all the water will spill out. That's how, when our blood starts to clot, it's this thing called antithrombin that "stops" it at just the right time, preventing it from happening too much. So, if you don't have enough antithrombin in your body, or if it's not working properly, you can have blood clots that keep happening, like the bathtub overflowing. This is why you're at an increased risk of developing abnormal blood clots .

People with this condition are particularly at risk of developing blood clots in the deep veins of the legs (`Deep Vein Thrombosis` or `DVT`) and the risk of a blood clot breaking off and getting stuck in a vein in the lungs (`Pulmonary Embolism` or `PE`) . These can be very dangerous conditions.

How common is this condition?

Antithrombin Deficiency is actually a relatively rare condition . It is estimated that only one in 2,000 to 3,000 people have it. That doesn't mean it doesn't happen to everyone.

What are the symptoms of antithrombin deficiency?

Not everyone with this condition will have the same symptoms. Some people may not have any symptoms at all. However, most often the first blood clot occurs before the age of 40 .

The most commonly seen symptoms are:

• Deep Vein Thrombosis (DVT): This can cause the leg to swell, become red, hurt, and feel warm to the touch.
• Pulmonary Embolism (PE): This can cause sudden shortness of breath, chest pain (especially when breathing), rapid breathing, coughing (sometimes with blood), and shortness of breath. This is a condition that requires emergency treatment.

In addition to these, although rarely, in the brain veins , or in the abdominal veinsThere is a possibility of blood clots forming.

Why does this antithrombin deficiency occur?

Most of the time, the cause of this condition is genetic , meaning it's something we inherit from our parents.

• Gene Mutation: Antithrombin Deficiency occurs in people who have a mutation (change) in the gene called `SERPINC1`. This gene instructs the body to make antithrombin.
• Inheritance: You can inherit this gene mutation from either parent. If so, you have a 50% chance of developing the condition. It doesn't matter whether it's a girl or a boy. However, babies who inherit this gene mutation from both parents usually don't survive. This is very rare.

The important thing is that not everyone with this gene mutation develops blood clots. Some people may live their entire lives without any problems.

How do doctors recognize this?

If you have these symptoms, or know someone in your family has this condition, it's a good idea to see a doctor and get checked out. The doctor will usually do the following:

• Physical exam: Your body will be examined.
• Medical history: You will be asked about your symptoms and whether anyone in your family has had similar problems.
• Blood test: The most important thing is to have a special blood test that checks the level of antithrombin in your blood.

These tests are the only way to confirm whether this condition exists or not.

What are you doing as treatment?

The treatment depends on whether or not you have a blood clot.

• If you have a blood clot: Your doctor may decide to start you on a blood thinner . This is most often warfarin (you may have heard of it as Coumadin). This may take several months, or it may be lifelong.
• If you have never had a blood clot: Even if you have antithrombin deficiency, if you have never had a blood clot, you usually do not need to continue taking blood thinners. However, in some cases (for example, before major surgery) they may be given for a short period of time.
• During pregnancy: Since between 3% and 50% of pregnant women with this condition can develop blood clots during pregnancy, the doctor may decide to give an injection of a medicine called `Heparin` to prevent blood clots from forming during that time.

How should I take care of myself? (While receiving treatment)

If you are taking blood thinners like Warfarin or Heparin, it is very important to take the medication exactly as your doctor tells you.Also, be sure to go to every appointment you have with the doctor.

Because this medication carries a risk of bleeding, your doctor should always check that you are receiving the correct dose. Blood tests such as the `Prothrombin Time` (PT) test are used to check whether the dose of Warfarin is correct.

By properly controlling the dosage of medication in this way, dangerous blood clots can be prevented and unnecessary bleeding can be prevented.

What can I do to reduce the risk of blood clots?

If you have antithrombin deficiency, there are several things you can do to reduce your risk of blood clots:

• Avoid taking birth control pills: especially those containing estrogen. Talk to your doctor about this.
• Avoid hormone therapy: Some hormone therapies taken after menopause can also increase the risk.
• Don't stay in the same position for too long: Especially when traveling long distances or working in one place for too long, get up at least every two hours and walk around a bit and shake your legs.
• Do not smoke and use tobacco products: Smoking is very harmful to blood vessels and greatly increases the risk of blood clots.
• Maintain a healthy weight: Obesity is another cause of blood clots.

In addition, things like major trauma, surgery, pregnancy, childbirth, and aging also increase your risk of blood clots. If you need to have surgery or are expecting a baby, tell your doctor about your condition. He or she may give you a special antithrombin concentrate as an intravenous (IV) injection, if needed.

Is there a way to prevent this situation from occurring?

Unfortunately, since it is a genetic condition, there is no way to prevent inherited antithrombin deficiency . We cannot change the genes we inherit from our parents. However, there are things we can do to reduce our risk of blood clots.

What to expect if you have antithrombin deficiency?

About one in three people with this condition will develop blood clots in adulthood.

• Surgery and immobility: If you are having surgery and are immobile for a long time (e.g., if you have to stay in bed), you are at higher risk of developing blood clots.
• Aging: This risk also increases slightly with age.
• Pregnancy: People with antithrombin deficiency may develop abnormal blood clots during pregnancy or after delivery, so special attention should be paid to this.

How long will this situation last?

Because it's a genetic condition, you're born with it. It's something that lasts a lifetime. That means it can't be cured completely. But, if managed properly, you can live with a lot less problems.

What is the outlook for this situation?

Your outlook depends on whether you have had a blood clot or not. Taking blood-thinning medication can help prevent another blood clot from forming. However, it is important to take the medication exactly as your doctor tells you, in the right dose, and for the right amount of time.

What should I be especially careful about?

If you have antithrombin deficiency, it's important to be aware of the warning signs of `DVT` (a blood clot in the leg) and `PE` (a blood clot in the lung) so you can get help quickly.

• DVT symptoms: swelling, pain, redness, and warmth to the touch in one leg (usually just one).
• Symptoms of PE: Sudden shortness of breath, chest pain (which worsens when breathing), rapid breathing, shortness of breath, cough (sometimes with blood).

If you are taking blood thinners (e.g. Warfarin), be aware of the following as there is a risk of bleeding:

• Be very careful when using sharp weapons (knives, razors, etc.)
• Avoid sports that can cause injury (e.g. rugby, boxing) as much as possible. Otherwise, wear proper protective gear.
• If the bleeding doesn't stop even from a simple wound, or if you develop bruises for no reason, tell your doctor.

When should I see the doctor?

If you suspect you have a DVT, see a doctor immediately. It is important to treat DVT quickly, as a blood clot in the leg can break loose and travel to the lungs, causing a PE.

If you are taking medication like Warfarin, tell your doctor immediately if you fall or if you have unusual bleeding (e.g., from your nose, gums, or stool).

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

In such a situation , you should immediately go to a hospital's Emergency Treatment Unit (ETU) :

• If you have symptoms of a `Pulmonary Embolism (PE)` (such as sudden shortness of breath, chest pain).
• What if you think you have symptoms of DVT , but you can't get in touch with your doctor?
• If you are taking blood thinners, if you hit your head, if you are vomiting blood, or if you cannot stop bleeding from a wound.

These are life-threatening emergencies, so don't delay.

What are the important questions I should ask my doctor?

Once you know you have this condition, you can ask your doctor questions like these:

• Do I need to take Warfarin or another blood thinner? How long do I need to take it?
• Is it a good idea to get other members of my family (parents, siblings, children) tested for Antithrombin Deficiency?
• What exercises can I do safely with this condition?
• Are there any special things I should be aware of before getting pregnant?

Ask questions like these to gain a better understanding of your situation.

Finally, things you need to remember (Take-Home Message)

Since Antithrombin Deficiency is a genetic condition, we cannot control it. However, by being aware of this condition and taking the necessary steps, you can live a much healthier life.

The most important thing is for you and your family to know the warning signs of DVT and PE so that if something goes wrong, you can recognize it early and seek treatment quickly.

Controlling your weight, staying active (regular exercise), and avoiding smoking can help you reduce your risk of developing unwanted blood clots. In this way, you can control the impact this condition has on your life to some extent. Talk to your doctor regularly and follow his or her advice carefully. Don't worry, you're not alone!
