Do you know about this disease that affects both your lungs and kidneys at the same time? Let's talk about Goodpasture Syndrome!

Do you sometimes have a persistent cough? Does that cough sometimes bring up a little blood? Or do you feel like you're having trouble breathing, or you're just tired and have a decreased urine output? These could be signs of something serious. Today we're going to talk about one such rare condition, but one that you should be aware of.

What is Goodpasture Syndrome?

Simply put, Goodpasture Syndrome is a rare but potentially life-threatening autoimmune disease . "Autoimmune" means that our body's defense system, the immune system, mistakenly starts attacking our own healthy cells and tissues.

In this disease, our immune system attacks a protein called collagen. Collagen is like a building block in our bodies. Collagen helps keep our skin, muscles, tendons, ligaments, and bones strong.

So, if you have Goodpasture syndrome, some of the proteins that your body makes, we call them antibodies, go and attach to the collagen in your lungs and kidneys. When this happens, inflammation starts in those areas, and that tissue starts to slowly break down. If left untreated, this can lead to severe inflammation of the kidneys (glomerulonephritis), which can lead to kidney failure. You can also start to bleed heavily from the lungs (pulmonary hemorrhage). In many cases, the main cause of death from this disease is bleeding from the lungs.

Another name for this is:

• Anti-glomerular basement membrane (anti-GBM) disease
• Goodpasture disease

How common is this?

This is a very rare disease. According to doctors, only one to two new cases of this disease are reported in every 100,000 people per year. So you can imagine how rare it is.

What are the symptoms?

Goodpasture syndrome is a `(pulmonary-renal)` condition. This means that both the lungs and the kidneys are affected at the same time. Often, the first symptoms to appear are related to the lungs. These are:

• Difficulty breathing (dyspnea): Not just when climbing stairs, but even when you are at rest.
• Chest pain : Chest pain when breathing or coughing.
• Cough : A persistent, sometimes painful cough.
• A noise comes from the chest when breathing : It may be a gurgling sound, as if something is stuck inside the chest.
• Feeling very tired `(fatigue)`: A feeling of being so weak that you can't do anything.
• Nosebleeds (epistaxis).
• Coughing up blood : This is a sign that scares many people and requires immediate medical attention.
• Pallor : The skin turns pale due to lack of blood.

Kidney-related symptoms may also appear later. They include:

• A decrease in red blood cells in the blood, that is, anemia .
• Blood in the urine (hematuria): The urine may turn red or dark brown.
• Less urine output than usual.
• High blood pressure .
• Nausea and vomiting : This can also occur with loss of appetite.

What causes this?

Goodpasture syndrome occurs when antibodies produced by our immune system attack the collagen in the glomerular basement membrane (GBM) in the kidneys. This GBM is part of the glomeruli, the tiny blood-filtering units in our kidneys. These antibodies also attack the collagen in the air sacs in the lungs. This causes the lung tissue to be destroyed, causing bleeding and making it difficult to breathe.

It is not yet known exactly why the immune system attacks its own collagen. It is possible that environmental factors and our genes may be involved in the condition. Studies have found that people with the disease have a strong association with a genetic marker called Human Leukocyte Antigen (HLA) DR15. This is a protein that helps the immune system distinguish between our own tissues and foreign substances.

Sometimes, this disease can appear after an infection, such as a cold or flu. Also, you:

• If you smoke .
• If you inhale drugs like cocaine .
• The risk of developing this disease is higher if you are exposed to metal dust or hydrocarbon chemicals such as methane and propane.

Who is this affecting the most?

Goodpasture syndrome can occur at any age, but it is most common in younger people, between the ages of ten and thirty, and then again in people in their 60s and 70s.

How is the diagnosis made?

When you see a doctor, they will ask about your symptoms and do a physical exam. In addition, they may also do the following tests to confirm Goodpasture syndrome:

• Blood tests : These check your estimated glomerular filtration rate (eGFR), which measures how well your kidneys are working.
• Urinalysis : This checks for blood in your urine or high protein levels (proteinuria).
• Imaging tests : A chest X-ray or CT scan is done to check for lung damage.
• Bronchoscopy : In this procedure, a doctor inserts a thin, long tube (bronchoscope) with a camera and light attached through your nose or mouth to check for damage inside your lungs.
• Kidney biopsy : In this, a small piece of tissue is taken from the kidney and examined under a microscope to confirm whether kidney disease is present.

Can Goodpasture syndrome be cured?

Yes, this can be cured if diagnosed correctly and treatment begins quickly.

How is it treated?

Treatment for Goodpasture syndrome varies depending on the severity of the condition. If the condition is not too severe, doctors may prescribe medications such as:

• Corticosteroids : For example, medications like prednisone. These help stop bleeding in the lungs.
• Immunosuppressant drugs : Drugs like cyclophosphamide. These stop your immune system from attacking its own tissues.
• Blood pressure medications (antihypertensives): These help control blood pressure and reduce damage to the kidneys.

In addition, doctors also use a treatment called plasmapheresis . This involves taking blood from a vein in your arm through a needle, separating the liquid part of the blood, called plasma, from the blood cells. The harmful anti-GBM antibodies are in this plasma. The plasma is then removed, and plasma from a healthy person is added back to your blood cells and given back to you. In simple terms, it removes the harmful antibodies from your body.

How long does it take to recover after treatment?

You will have to take immunosuppressant drugs for about 6 to 12 months. In many cases, you may have to do plasmapheresis every day for several weeks.

What will happen next?

If left untreated, Goodpasture syndrome can lead to life-threatening bleeding from the lungs and kidney failure. However, if the disease is recognized early and treatment is started, the outcome is usually good. Your body only produces those harmful antibodies for a short time – from a few weeks to about two years. Relapses or recurrences are very rare.

The most serious complication of this is kidney failure. If this happens, you may need dialysis or a kidney transplant .

What do I have to say about my lifetime?

About 80% of people with Goodpasture syndrome have a five-year survival rate of 80%. That's if the disease is diagnosed early and treated properly.

Can this be prevented?

It may not be possible to completely prevent it. However, you can reduce your risk by avoiding certain things:

• Hydrocarbons, which means things like methane, propane, gasoline, kerosene, and tar.
• Metal dust.
• Cocaine.
• Hair-coloring products.

How can I take care of myself?

If you have Goodpasture syndrome, it's a good idea to do these things:

• Quit smoking completely. Avoid being in places where other people smoke (i.e. avoid exposure to secondhand smoke).
• Engage in physical activity for at least 30 minutes every day.
• Try to reduce stress .

When should I see a doctor?

If you cough up blood, have difficulty breathing, have decreased urination, or have any of the other symptoms listed above, see a doctor immediately. Early detection greatly increases your chances of recovery. If left untreated, it can cause permanent kidney damage and even fatal lung problems.

What questions should you ask the doctor?

When you see a doctor, you can ask these questions:

• How do I know for sure if I have Goodpasture Syndrome?
• How serious is my condition?
• What treatments do you recommend?
• What can I do to take care of my kidneys?
• Should I see a nephrologist or a pulmonologist?
• Can you tell me about a support group that helps people with this disease?

What are the three main features (Triad) of Goodpasture syndrome?

In medicine, a ``triad'' refers to three main symptoms that describe a medical condition. The three main symptoms of Goodpasture Syndrome are:

• Bleeding from the lungs.
• Rapid increase in inflammation of the kidneys.
• The presence of those antibodies called ``anti-GBM antibodies'' in the body.

Having this disease can be really distressing and lonely, especially since the exact cause is still unknown. It can interfere with your daily activities, and you may even have to change jobs if you work with metal powder, gasoline, or tar.

Finally, what to remember

So, Goodpasture Syndrome is something to be afraid of, but if you recognize the symptoms early, see a doctor quickly, and start treatment, you can get very good results. Be aware of changes in your body. If you feel something strange, it is important to seek medical advice without dismissing it as something minor. You are not alone, and doctors can help you.
