Can your blood vessels be damaged too? Let's talk about Fibrinoid Necrosis!

The tiny blood vessels that are spread all over our body are like pipes that carry water. These are the ones that carry blood to all parts of our body. So, what happens if something damages these blood vessels? Today we are going to talk about a condition that can be serious, and that is a condition called Fibrinoid Necrosis . Don't be afraid, let's understand this simply.

What is fibrinoid necrosis?

Simply put, fibrinoid necrosis is damage to the inner walls of the small blood vessels in our bodies, especially the small arteries . Think of it like a water pipe bursting. When blood vessels are damaged in this way, they can rupture, become injured , bleed, and even bruise inside the body.

The word “necrosis” means cell death . It means the death of cells due to an accident, injury, or loss of blood supply. Fibrinoid necrosis is a similar phenomenon, meaning that the cells in the walls of blood vessels die.

How does this situation arise?

This may seem a bit complicated, but think about it this way. We have an immune system in our bodies. It's like a defense force in our bodies. It's this system that protects us from disease . But sometimes this immune system becomes overactive or confused.

In fibrinoid necrosis, the immune system becomes overactive and releases certain substances. These substances stick to the inner walls of our blood vessels. Then there is inflammation , which means swelling and redness. This inflammation causes the cells in the walls of the blood vessels to die. In other words, it is as if our own defenses are attacking our own cells.

What causes fibrinoid necrosis?

Any condition that can damage blood vessels can cause this. There are several main contributing factors:

• Very high blood pressure : This is called (Malignant Hypertension) or (Hypertensive Crisis) . Normally, the blood pressure of a healthy person should be less than 130/80 mmHg. However, in this condition (Malignant Hypertension), the blood pressure rises to 180/120 mmHg or even higher. When this happens, the veins that carry blood to important organs like our heart , brain, and kidneys can be damaged and fibrinoid necrosis can occur. This is a very serious emergency and requires immediate medical attention.

• Autoimmune diseases : As mentioned earlier, these are diseases in which our own immune system attacks our own body. For example:
• (Rheumatoid Arthritis )
• (Lupus) (Lupus disease – affects many organs such as skin, joints, kidneys)
• (Rheumatic Fever – a condition that can occur after a throat infection and affects the heart)

• Preeclampsia: This is a condition that some mothers develop during pregnancy. It is characterized by high blood pressure and other symptoms.

• (Subacute Bacterial Endocarditis): This is a bacterial infection of the inner lining of the heart.

• Vasculitis: Simply put, it is inflammation of the blood vessels, which means swelling. Examples of this include:
• (Polyarteritis Nodosa)
• (IgA Vasculitis) (formerly known as Henoch-Schönlein purpura)

Now you probably understand that this condition is not caused by just one reason, but can be associated with various illnesses.

What are the symptoms of this condition?

Because fibrinoid necrosis damages blood vessels, the main symptom is bleeding . This can occur in various ways:

• Bleeding gums.
• Blood in the stool (black or dark red).
• Blood in the urine – we call this (Hematuria) .
• Bruising in various places on the body (as if bruised without being hit anywhere).
• Bleeding inside the body (this is not visible from the outside, but can be understood from other symptoms).
• Nosebleed.

If you have bleeding like this, don't ignore it . It's very important to seek medical advice.

What are the possible complications of Fibrinoid Necrosis?

The complications that arise from this condition usually depend on the underlying disease that caused it. Consider, for example:

• The malignant hypertension we talked about, that is, if fibrinoid necrosis occurs in the blood vessels of the kidneys due to high blood pressure, it can lead to kidney failure .
• If this condition occurs due to a disease like lupus , skin lesions and heart disease can occur.

That means that complications are determined not only by fibrinoid necrosis, but also by the underlying disease.

How is this disease diagnosed? (Diagnosis)

When cells die, they release a substance called fibrin . This substance called fibrin is the main evidence to identify this disease.

Pathologists , who are specialists in diagnosing diseases, take a sample of damaged tissue and look at it under a microscope. They can then see if this substance (Fibrin) is deposited.

Taking a tissue sample is called a biopsy . The way this biopsy is done varies depending on the location of the disease:

• Skin biopsies: A thin layer of skin may be scraped off the surface of the skin, or a small piece may be taken with a special tool (punch tool). Sometimes a small incision may be made to take a sample from deeper.
• Internal biopsies: To take a tissue sample from an organ inside the body, doctors use a needle or an instrument called an endoscope . An endoscope is a thin tube with a camera and small instruments on one end. This can be passed inside the body to take a tissue sample.

How to treat?

To be honest, there is no specific, standard treatment for fibrinoid necrosis. However, doctors can control the bleeding . It depends on the location and nature of the bleeding.

In addition, the most important thing is to treat the underlying disease that caused fibrinoid necrosis .

For example, if high blood pressure is the cause, medication is given to control it. If it's a problem with the immune system, there are medications to control it and stop further damage to the blood vessels.

Therefore, the primary focus of treatment is to treat the underlying cause .

How to protect yourself from fibrinoid necrosis? (Prevention)

Rather than trying to completely protect yourself from this, the best thing you can do is reduce the risk of developing the underlying conditions that cause it.

• See your doctor regularly for checkups. That way, if there is a health problem, it can be identified and treated before it becomes serious.
• If you already have a condition that could cause this (e.g. high blood pressure, diabetes, autoimmune disease), follow your doctor's instructions exactly . Take your medications on time and maintain your lifestyle as prescribed.

What is the future for someone with this condition? (Prognosis)

This really depends on the severity of the underlying condition that caused the fibrinoid necrosis. Some conditions can be lifelong, reduce quality of life, and may even lead to premature death.

For example, if the aforementioned condition (Malignant Hypertension) is not treated promptly, the patient's life expectancy can be reduced by as much as two years. That is why it is important to seek medical advice as soon as symptoms appear.

When should you see a doctor?

If you ever find out that you have damaged blood vessels, or if you have any of the symptoms mentioned earlier (especially unexplained bleeding), it is essential to see a doctor for proper follow-up.

By following the treatment plan your doctor gives you exactly, you can control your condition and prevent further damage.

Fibrinoid necrosis is a condition that damages blood vessels. The conditions that cause it can be serious, so close monitoring by a doctor is necessary. By seeing your doctor regularly, you can better manage your health and prevent complications from underlying conditions.

Take-Home Message

• Fibrinoid necrosis is damage to small blood vessels.
• The main causes of this are conditions such as high blood pressure and autoimmune diseases.
• The main symptom is various types of bleeding.
• A biopsy may be needed to diagnose the disease.
• Treatment is primarily directed at the underlying cause.
• It is very important to seek medical advice if you have symptoms or risk factors, as it can be serious if ignored.

I hope this information is useful to you. Stay healthy!
