Do you also have a persistent dry cough and wheezing? Let's talk about NSIP (Nonspecific Interstitial Pneumonia)!

Do you have a persistent dry cough that has been going on for days, maybe weeks? Do you find it hard to breathe, even when walking a short distance, doing household chores, or climbing stairs? Most of the time, we dismiss these things as "just a cold." But sometimes, behind these symptoms, there may be a lung condition that we haven't heard much about, but that we should definitely be concerned about. Today, we're talking about one such disease, NSIP, or Nonspecific Interstitial Pneumonia.

Simply put, what is NSIP (Nonspecific Interstitial Pneumonia)?

Although the name may seem a bit complicated, let's keep it simple. NSIP is also an inflammation of the lungs. But it's a little different from the common pneumonia we often hear about.

Think of your lungs as an organ made up of millions of tiny, grape-like air sacs (alveoli). When we breathe, oxygen enters the lungs and enters the blood through these alveoli. In NSIP, inflammation occurs not in the alveoli themselves, but in the spaces between them and the tissues surrounding the blood vessels . This is what we medically call ``interstitial lung disease''.

This condition is often seen in people with connective tissue disease (CTD). It can also be associated with other medical conditions. Unlike a simple pneumonia, which usually resolves in a few days, it can last for a long time and can sometimes cause permanent scarring of the lungs.

There are two main types of NSIPs.

Doctors divide NSIP into two main types, depending on the type of damage to the lungs. It is important for you to know these two types, because treatment and prognosis depend on the type.

Is this different from regular pneumonia?

Yes, definitely. It is very important to understand this difference.

• Pneumonia: This is an inflammation of the air sacs (the grape-shaped sacs) in the lungs . They may fill with pus or fluid. This is often caused by a bacterial or viral infection.
• Interstitial pneumonia (like NSIP): In this, inflammation occurs in the spaces between the air sacs. This means that the structure and framework of the lungs are damaged. Often, a specific cause for NSIP cannot be found.

Another thing is, `Usual Interstitial Pneumonia (UIP)` is another name used for the disease `Idiopathic Pulmonary Fibrosis (IPF).` IPF is an irreversible, serious disease that causes scarring in the lungs. However, NSIP, especially Cellular NSIP, can often be cured with treatment. So, don't confuse the two.

What are the symptoms of NSIP?

The symptoms of NSIP may not be very noticeable at first and may gradually worsen over time. It is important that you are aware of these symptoms.

• Dry cough: This is the main and most common symptom. A persistent, irritating cough without mucus.
• Shortness of breath: At first, it may be felt during exercise or brisk walking. However, as the disease progresses, it may become difficult to breathe even when just standing still.
• Labored breathing: Feeling like you have to make a lot of effort to breathe.
• Fatigue: Feeling tired and exhausted even without doing any work.
• Clubbed fingers: This is uncommon, but some people may have rounded fingertips and swelling around the nails.

What causes NSIP? What are the risk factors?

To be honest, experts still don't know exactly what causes NSIP. But when you look at people with this disease, they find that they have other medical conditions. That means that while it's not true that these conditions cause NSIP, there is a strong connection between them.

The following things increase the risk of developing NSIP.

How does a doctor diagnose this disease?

When you go to the doctor, he will first listen carefully to your symptoms. You should also tell the doctor about any other medical conditions you have and the medications you are taking. Then, he will order several tests to diagnose the disease.

• Pulmonary function tests: This involves having you breathe into a machine, which measures how much air your lungs can take in and how quickly you can breathe out.
• Chest X-ray: This helps to get a basic understanding of whether there are any abnormalities in the lungs.
• CT scan (Computed Tomography scan): This can produce much clearer, three-dimensional images than an X-ray. A CT scan is essential to accurately assess the extent of lung damage and its nature (cellular or fibrotic).
• Bronchoscopy: A small, lighted tube with a camera is passed through the mouth or nose into the lungs to examine the inside of the airways. If necessary, a sample of cells can be taken for testing.
• Biopsy: This is the best test to confirm the disease 100%. In this, a very small piece of tissue is surgically removed from the lung and examined under a microscope.

What are the treatments for NSIP?

Doctors have two main goals when treating NSIP. One is to reduce the inflammation in the lungs. The other is to control any underlying medical conditions (such as arthritis) that may be causing NSIP.

In severe cases, other treatments are also used to strengthen the lungs and provide the body with the necessary amount of oxygen.

• Medications:
• Corticosteroids such as Prednisolone: ​​These are steroid-type medications that quickly reduce inflammation.
• Immunosuppressive drugs: Drugs like `Azathioprine`, `Cyclophosphamide`, and `Mycophenolate` work by controlling the activity of the body's immune system and stopping it from damaging its own lungs.
• Anti-fibrotic drugs: Drugs like `Pirfenidone` and `Nintedanib` are used in people with Fibrotic NSIP. These slow down the rate of scarring in the lungs.
• Rituximab: This is a ``biologic`` drug used for connective tissue diseases.
• Other Therapies:
• Pulmonary rehabilitation: This is a special exercise and counseling program that helps manage breathing difficulties and strengthen the body.
• Oxygen therapy: Oxygen is given through a tube to those with low blood oxygen levels.
• Lung transplant: This is the last option considered for those with very severe disease who have failed all other treatments.

What will life be like with this disease?

The answer to this question directly depends on which type of NSIP you have.

What questions should I ask the doctor?

If you've been diagnosed with NSIP, it's normal to have a lot of questions on your mind. When you go to see your doctor, don't forget to ask these questions.

• Is there a specific reason why I might have this condition?
• Which type do I have, Cellular or Fibrotic?
• What treatment options are best for me?
• Are there any side effects to these treatments?
• How likely is it that this disease will worsen over time?
• Can I slow down further lung damage?
• What things should I be especially careful about in my daily life and food and drink?
• When should I see the doctor again?

Asking questions like these and gaining a clear understanding of your condition will greatly help you support your treatment.
