Do you sometimes feel like your body is very heavy, you have pain in places for no reason, or you always feel like you have a cold, but it's not like a common cold? Sometimes, behind these things, there may be a disease that we don't hear much about, but it's important to know. That's one of those conditions called GPA.
What is GPA (Granulomatosis with Polyangiitis)? Let's understand it simply!
Okay, now let's see what this GPA (Granulomatosis with Polyangiitis) is. Don't worry, I'll explain it simply. It used to be called `(Wegener's Granulomatosis)`. But the name `(Granulomatosis with Polyangiitis)` that is used now says a lot about this disease.
Simply put, GPA is inflammation or swelling of your blood vessels. Doctors call this ``vasculitis.`` Think of it this way: the blood vessels throughout our bodies are like water pipes. When something goes wrong with these pipes, blood flow is disrupted, right? That's what's happening here.
Now there are two more special things about this GPA:
- Polyangiitis: This means that the inflammation occurs in many different blood vessels in your body, especially the small ones . It is not limited to just one area.
- Granulomatosis: This may sound like a complicated word, but it simply means that small, lumpy, inflammatory lumps called granulomas form in your blood vessels and certain organs. These lumps can damage your blood vessels and organs.
So, there are many types of this ``vasculitis'' condition, but the type called GPA mainly affects the smallest blood vessels in our body. Because these small blood vessels are all over the body, GPA can cause problems in many parts of the body, especially organs that have a lot of small blood vessels. Most often, it affects your respiratory system (the breathing system) and kidneys.
This inflammation of the blood vessels can cause them to swell, burst, and even bleed. Also, the blood vessels can become narrowed due to scarring. What happens then? Our tissues do not get the oxygen and nutrients they need. Sometimes, GPA can even cause a condition called ``pulmonary-renal syndrome``, in which blood leaks from the kidneys and lungs.
What symptoms occur when GPA develops?
Now you're probably thinking, 'Okay, if this is a disease like this, how do we recognize it? What are the symptoms?' Let's talk about that.
As mentioned earlier, GPA most commonly affects the respiratory system and kidneys. However, it can also affect many other organs and tissues, as well as your general well-being. This is because it targets small blood vessels throughout the body.
Sometimes, vasculitis, an inflammation of your connective tissues, can cause muscle pain, joint pain, and a feeling of malaise . Fatigue, loss of appetite, and weight loss are also common symptoms.
Respiratory system symptoms
Many people first suspect they have GPA and seek treatment because of respiratory symptoms. In the early stages, these symptoms may resemble a common cold, flu, or flu. However, they tend to last longer than usual. Check to see if you have any of these:
- A severe headache or pressure in the sinus area.
- Sinus infections occur frequently.
- There is a constant runny nose, and crusts form around the nostrils.
- My nose feels stuffy.
- Frequent nosebleeds for no reason.
- I have an earache.
- I feel a pain in my chest.
- I have a persistent cough.
- Feeling short of breath (like a cough).
As GPA gets more severe, you may develop an inflammation (polychondritis) of the cartilage in your ears, nose, and throat. This can cause more serious symptoms, such as:
- The nose swells so much that the top of the nose sinks inward (this is also called a saddle nose).
- The throat, or the upper part of the windpipe, becomes narrowed (subglottic stenosis). This can cause a hoarse voice and a whistling sound when breathing (wheezing or stridor).
- Inflammation of the inner ear can cause dizziness (vertigo) and hearing loss.
Also, you may be bleeding from your lungs. If this happens, you may have increased difficulty breathing, or you may even cough up blood .
Kidney-related symptoms
You may not feel any pain in your kidneys when you have GPA. However, you may notice changes in your urine. For example, foamy urine or blood in your urine. Also, swelling of the face or legs (edema) is another symptom of kidney disease.
If you have GPA, doctors will check your kidneys regularly, even if you never have symptoms. This is because GPA may not affect your kidneys in the early stages, but over time, it will almost certainly affect your kidneys.
Eye-related symptoms
GPA can also affect your eyes. It can cause inflammation on the surface or inside of the eye. This can cause eye pain, pressure, redness, and swelling . In severe cases, vision loss is possible.
Skin symptoms
Vasculitis in your skin can cause symptoms like:
- The skin surface looks like a blue-red pattern (mottled skin).
- Purple, red, or brown spots (purpura) appear.
- Hard lumps (nodules) or small blister-like bumps (papules) may appear on the skin.
- Non-healing wounds (ulcers) may occur.
Nervous system symptoms
GPA can also affect your nervous system. Most often, it affects your peripheral nervous system – the nerves that run from your spinal cord to other parts of your body.
Inflammation and swelling can damage just one nerve, causing symptoms in one area (mononeuropathy). However, more often, multiple nerves are affected (polyneuropathy). Symptoms may include:
- Motor symptoms: Like muscle weakness.
- Sensory symptoms: numbness, tingling, or nerve pain.
- Impaired function of the autonomic nervous system, which controls blood pressure, bladder function, or sweating.
What are the serious complications that can occur due to GPA?
If GPA is not properly controlled, it can sometimes be life-threatening and cause serious organ damage. So it's important to be aware of this. Here are some of the serious complications that can occur:
- Pulmonary hemorrhage: This can cause difficulty breathing and respiratory failure.
- Rapidly progressive glomerulonephritis: This can lead to kidney failure.
- Permanent loss of vision or hearing.
- Loss of skin sensation or inability to control muscles (peripheral neuropathy).
What causes GPA to develop?
Now you might be wondering, 'Why does this kind of disease occur?' Actually, GPA, like other types of `(vasculitis)`, is an `(autoimmune disease` . This may seem a little difficult to understand, but I'll explain it simply.
Normally, our immune system is like our protector. It fights off diseases and germs by causing inflammation. However, in these autoimmune diseases, our own immune system mistakenly starts attacking our own healthy cells and tissues. In GPA, the immune system attacks our own blood vessels.
What are the specific triggers that cause GPA?
Researchers still don't know exactly what causes autoimmune diseases. However, they believe that several factors contribute to them. Sometimes, our immune system is put into overdrive due to stress, which can cause it to malfunction. Research has also found that GPA can occur after severe bacterial and viral infections .
GPA belongs to a group of diseases called ANCA-associated vasculitis, or AAV . These are types of vasculitis that involve a specific antibody called ANCA. Researchers believe that this ANCA plays a key role in causing inflammation in these diseases, including GPA.
How do you find out if you have a GPA?
If you have symptoms of GPA, your doctor will first ask you about your symptoms and perform a physical examination. If your symptoms and medical history suggest that you may have GPA, they will order some tests to investigate further.
Among the tests used to determine whether you have a GPA are:
- Blood tests: This also checks for the presence of the previously mentioned ANCA antibodies.
- Urinalysis: This tests your urine for blood and protein.
- Chest X-rays and CT scans: These check the condition of your lungs.
- A biopsy: A small piece of tissue is taken from the lungs, sinuses (nasal cavities), or kidneys and examined under a microscope to see if there are any specific inflammatory conditions.
What are the treatments for GPA (Wegener's Granulomatosis)?
Okay, now let's look at how GPA is treated. Doctors treat GPA by using medications that reduce inflammation and suppress the immune system (corticosteroids and other immunosuppressants).
Some of these medications are more potent than others. The combination of medications your doctor recommends will depend on the severity of your condition and your risk of side effects.
Basic treatment for active GPA:
- High doses of corticosteroids (e.g., prednisone) are given. These doses are gradually reduced over time.
- `(Rituximab)`: This is a new biologic medication. This is now the standard treatment most often used.
- Cyclophosphamide (for severe cases) or methotrexate (for mild cases): These drugs are also used to treat cancer. However, when given for GPA (in much lower doses), they act as immunosuppressants.
- Avacopan: This medication can be used as an additional treatment to reduce the dose of corticosteroids.
If you have severe complications, you may need additional treatments. For example:
- Dialysis (if kidneys fail)
- Organ transplantation
Once GPA reaches a state of ``remission'' , meaning symptoms have disappeared and the disease has become dormant, mild medications are given to maintain the condition. This usually includes:
- `(Rituximab)`
- Mild immunosuppressive drugs: For example, `(azathioprine)`, `(methotrexate)` or `(mycophenolate mofetil)`.
Throughout your treatment, you will continue to have tests to monitor your condition and how you are responding to treatment. Your doctor will adjust your prescription and dosage based on your response.
Remember, all medications can have side effects. They can occur at any time during treatment. Therefore, it may be necessary to switch medications to prevent or reduce some side effects. All of these decisions should be made in consultation with your doctor.
What will the future hold for this condition? (Outlook)
GPA is a lifelong condition that requires lifelong care. With treatment, the disease can go into remission and symptoms can disappear. However, symptoms can also come back (relapse).
You may need to take medication periodically throughout your life to control relapses. Because these medications suppress your immune system, you will also need to take extra care to protect yourself from other illnesses.
Is it possible to live a normal life with a GPA?
With effective treatment, you can live a relatively normal life with GPA. As with many chronic illnesses, there can be periods of remission and relapse. So the course of the disease can be somewhat up and down.
What is the life expectancy of someone with a GPA?
Without treatment, the average life expectancy is about five months, with less than 50% of people surviving beyond a year. However, with treatment, follow-up studies show that more than 80% of people are still alive after eight years . So you can see how important it is to get treatment, right?
What is the most common cause of death in GPA?
Before treatment, organ failure is the biggest risk of death in GPA. During treatment, when your immune system is weakened, you are at higher risk of life-threatening infections .
How should I take care of myself while living with GPA?
When you're living with a chronic autoimmune disease like GPA, it's important to have some awareness of your body. Even when you're feeling perfectly healthy, you need to stay safe.
Take steps to protect yourself from common illnesses while taking immunosuppressant medications. If you notice any new or unusual symptoms , tell your doctor right away.
GPA can affect you in many ways, some of which are life-threatening. Recognizing that something is wrong and getting treatment for it early can make a big difference.
Many people can live symptom-free, at least for some time, with treatment. But your medical team will continue to monitor your condition. They will be your lifelong partners in maintaining your health.
