Are you suddenly experiencing blisters on your skin that itch? This could be Bullous Pemphigoid!

Have you suddenly developed a rash on your skin that was not there before, and itchy, sometimes water-filled blisters? You may also want to know about a condition called bullous pemphigoid. It's a rare skin condition, but it's worth being aware of. Let's talk about it in a simple way that you can understand.

What is Bullous Pemphigoid? What kind of condition is it?

Simply put, Bullous Pemphigoid is a rare skin condition that causes red, itchy welts on the surface of the skin, similar to eczema. Sometimes, these welts can develop into fluid-filled blisters. Think of it like a mosquito bite, with large blisters that itch a lot.

These blisters can appear in just a small area of ​​the body, or they can spread all over the body. They are most often seen in areas where the skin folds. For example, under the armpits (axilla), in the groin, or on the abdomen. Some people may also develop these blisters in places like the inside of the mouth, tongue, throat, esophagus, or even the eyes.

Now you may be wondering, "Why is this happening?" Bullous pemphigoid is an autoimmune disease . This means that our body's immune system, which is supposed to protect us, mistakenly attacks the tissue under our own skin. It's like our own army attacking our own country.

Who is most likely to develop this? How common is it?

Bullous pemphigoid is a condition that is most common in people over the age of 60. However, it can also occur in younger people. Although it is quite common in Western countries, it is not so common in Asian countries, that is, in our part of the world.

This can happen to both men and women, regardless of gender.

Is there a connection with neurological diseases?

Yes, people with certain neurological disorders have been found to be slightly more likely to develop bullous pemphigoid. These include:

• Dementia
• Parkinson's disease
• Stroke
• Epilepsy
• Multiple sclerosis

This doesn't mean that everyone with these conditions will develop bullous pemphigoid. However, doctors say there may be a connection.

It is so common that the general population has a reported incidence of between 2.4 and 23 per million. However, among people aged 80 or older, the incidence is between 190 and 312 per million . This means that the likelihood of developing it increases as you get older.

Is bullous pemphigoid dangerous? Can it be life-threatening?

This may sound a little scary to you. But here's the truth: yourBullous pemphigoid can be life-threatening if you are in poor health or if you don't treat it properly, especially if your blisters break and become infected. That's why we say to see a doctor right away if you notice anything unusual.

What are the symptoms? How do you recognize it?

The main symptoms of bullous pemphigoid are the appearance of numerous itchy, eczema-like red lesions (welts) or fluid-filled blisters (bullae) . These are most commonly seen on:

• In the hands
• In the legs
• In the stomach area
• In the groin area
• Inside the mouth

These blisters usually form in folds of the skin, along the skin's creases. Most of the time, they are not painful , but if they break, they can become painful and sore, and can even become ulcers.

The fluid inside the blister may be clear or slightly bloody. The skin around the blister may be normal or may be discolored (red, purple, brown, or a slightly darker color than your skin tone).

The good news is that this rash and blisters are very unlikely to cause scarring.

Why does bullous pemphigoid develop? What are the causes?

As we mentioned earlier, bullous pemphigoid is a disease caused by a malfunction in the immune system. However, doctors and researchers still haven't found a definitive reason why our immune system reacts this way.

Some medications can cause or worsen this condition. For example, the diabetes drug alogliptin. Ultraviolet (UV) light and ionizing radiation from sunlight can also cause or worsen this condition.

Can certain foods and drinks increase this?

This is a question that many people ask. In fact, doctors still don't have clear scientific evidence to prove that there is a connection between food and bullous pemphigoid. Some people say that their symptoms have improved when they cut out certain foods from their diet. However, there is no strong evidence to prove this yet.

If you have bullous pemphigoid, talk to your doctor about whether eliminating certain foods and drinks can help. He or she may tell you to keep a food journal . You can then see if certain foods make your symptoms worse. If you notice that they do, you can gradually eliminate those foods and see if that helps.

Is this a contagious disease?

No, bullous pemphigoid is not contagious. It cannot be spread to another person through skin-to-skin contact. So don't worry about it.

How does a doctor diagnose this accurately?

When you go to see a doctor, he or she will first examine the affected areas of your skin. Then they will ask you some questions. For example:

• "When did these symptoms start?"
• "Do you have pus or blood in your blisters?"
• "Did you have a fever?"
• "Have you started any new medications?"

After asking questions like these, the doctor comes to a basic conclusion based on the answers you give.

What tests are being done for this?

To confirm the diagnosis, your doctor may recommend that you have these tests:

• Blood test: A small needle is used to take a sample of blood from a vein in your arm and send it to a laboratory for testing.
• Skin biopsy: This involves taking a small piece of your skin and sending it to a lab for testing. This is often the only way to confirm the exact cause of the condition.

What are the best treatments?

In mild cases of bullous pemphigoid, the best treatment is to apply corticosteroid creams or ointments directly to the affected areas.

However, in moderate-to-severe cases , your doctor may give you oral corticosteroid pills, such as prednisone , in addition to corticosteroid cream. They may also give you other immunomodulatory agents that can help reduce the use of steroids. For example, drugs such as dapsone, mycophenolate mofetil, azathioprine, methotrexate, or chlorambucil.

If you cannot take corticosteroids or other immune-suppressing medications, your doctor may prescribe tablets called tetracycline or doxycycline .

Sometimes, if these treatments do not control the disease (refractory cases), the doctor may also recommend treatments such as Rituximab or IVIG infusion (a liquid given into a vein) .

The most important thing is, do not use any medication without consulting a doctor. He or she is the one who will determine the best treatment for your condition.

Are there any remedies that can be done at home?

There are no specific home remedies for bullous pemphigoid. However, there are some things you can do to help reduce your symptoms and provide some relief.

For blisters on the skin:

• Wear soft, loose-fitting clothes made from natural fibers (e.g. cotton).
• Don't stay in the sun for too long. If you go out, wear sunscreen.
• Keep your wounds or sores clean by washing them with antibacterial soap and water. After you do this, apply an antiseptic cream to the wounds and cover them with a nonadhesive bandage. This can help prevent infection.
• If you have bullous pemphigoid on your legs, avoid standing or walking for long periods of time.
• Apply a moisturizer, cream, coconut oil, or shea butter to keep your skin moisturized.

• When eating hot foods, wait until they are cool before eating.
• Avoid eating brittle, sharp foods (e.g. chips, cereal, bread crumbs, raw vegetables and fruits).

• Avoid drinking alcohol.

How soon will I feel better once I start treatment?

You should start feeling better within a few days of starting treatment. However, this can vary from person to person.

Is there a way to prevent this from happening?

Unfortunately, doctors and researchers still don't know of a way to prevent bullous pemphigoid from developing.

What happens if I get this disease? What will happen in the future?

Bullous pemphigoid usually gets better on its own within about five years. It responds well to treatment. However, sometimes the disease can flare up and sometimes it can go into remission. During periods of remission, you may be able to stop treatment (with your doctor's advice).

If your blisters burst and become infected, you are at risk of developing a life-threatening condition called sepsis . Therefore, it is very important to take care of your blisters.

What are the best times to see a doctor?

If you have unexplained blisters , see a doctor as soon as possible. As mentioned earlier, it's best to get a diagnosis and treatment as soon as possible.

Important questions to ask your doctor

When you go to see a doctor, it may be helpful to ask these questions:

• "How can you say I have bullous pemphigoid?"
• "If I don't have bullous pemphigoid, what other skin disease could I have?"
• "How can I manage my symptoms?"
• "What medications do you recommend for me?"
• "Do those medications have side effects?"
• "What else should I do to improve my symptoms?"
• "How long will I have this bullous pemphigoid condition?"
• "Should I see a dermatologist or another specialist?"

What is the difference between Bullous Pemphigoid and Pemphigus Vulgaris?

Both are diseases that cause blisters on the skin due to a malfunction of the immune system. Pemphigus vulgaris has similar symptoms to bullous pemphigoid. However, pemphigus vulgaris often starts in the mucous membranes inside the mouth. Very few people develop blisters on the skin. Also, the blisters in pemphigus vulgaris are more fragile than the blisters in bullous pemphigoid.

When pemphigus vulgaris blisters appear, they are often erosions, not blisters that don't break as in bullous pemphigoid. If you have pemphigus vulgaris, the top layers of your skin will easily separate from the bottom layers with a little pressure or rubbing (this is called the Nikolsky sign) .

Although almost everyone with bullous pemphigoid has skin effects, only about a third (33%) of them develop blisters in the mouth .

Finally, take-home message
