Is your skin blistering and breaking out from even the slightest touch? Could it be Epidermolysis Bullosa (EB)?

Sometimes our skin is very sensitive, isn't it? Even if something small hits it, or a piece of clothing is torn, some people easily get blisters and skin injuries. Especially since the skin of small babies is very delicate, it feels very scary when you see such things. So today we are going to talk about a disease that occurs in such skin, which is a little rare but very important to know. That is epidermolysis bullosa, or EB for short.

What exactly is epidermolysis bullosa (EB)?

Simply put, epidermolysis bullosa (EB) is an inherited condition . It causes your skin to become very fragile and blister and peel easily. Sometimes, even if you rub your skin with clothing or get hit somewhere, you can develop blisters and sores. For some people, it may be mild and only cause painful blisters on the hands, elbows, knees, and feet. However, in severe cases, these blisters and sores can appear anywhere on the body. EB symptoms can range from mild to very severe .

Remember, sometimes these blisters can develop inside the mouth, throat (esophagus), eyes, and other internal organs of the body. When these blisters heal, they can leave painful scars. In severe cases, these blisters and scars can damage internal organs of the body, which can be life-threatening.

What are the main types of EB?

There are four main types of EB, which are identified by the layer of skin affected.

1. EB Simplex (EBS): This is the most common type of EB. It can range from mild, not very painful, to very painful, severe, in some people. The blisters form in the top layer of the skin, the epidermis . Scarring is rare after these blisters heal.

2. Junctional EB (JEB): In JEB, blisters form inside the mouth and airway. This is somewhat rare , and can range from mild (slightly uncomfortable, mildly painful) to severe.

3. Dystrophic EB (DEB): In DEB, blisters form in the middle layer of the skin, the dermis . This can also vary from mild to severe.

4. Kindler Syndrome: In Kindler Syndrome, blisters can form on almost all layers of the skin. This is very rare .

Doctors distinguish EBS, JEB, and DEB based on the layers of your skin that are affected. In Kindler syndrome, blisters can appear throughout different layers of your skin.

Who is most affected by this condition? How common is it?

EB can affect anyone. People of any race, ethnicity, or gender can develop EB. However, if one of your parents has the disease, you are more likely to develop EB.

As common as it is, according to statistics in the United States, only about one in 50,000 people suffer from EB. This means it is a relatively rare condition.

What effects can EB have on the body?

In severe cases of EB, the eyes can blister and even cause vision loss . Sometimes, severe scarring and deformity of the skin and muscles can occur, making it impossible to move the fingers, hands, feet, and joints properly. Some people with EB have an increased risk of developing a type of skin cancer called squamous cell carcinoma .

In the most severe cases, death can sometimes occur in infancy . This is due to conditions such as severe infections (for example , sepsis ), difficulty breathing due to airway obstruction, dehydration, and malnutrition.

Can EB be fatal?

This really depends on the type of EB you have. Mild, less severe forms of EB are not fatal. However, the life expectancy of people with severe forms of EB can range from infancy to about 30 years old. So this is a condition that needs a lot of attention.

What are the symptoms of EB?

The symptoms of EB vary depending on the type. These symptoms usually appear when you are a baby or young child . Some symptoms are common between different types. Here are some of the main symptoms of EB:

• Blisters on the skin (hands, feet, elbows, knees) or inside the body.
• Thickening of the skin on the palms and soles of the feet, making them feel like calluses.
• Decrease in red blood cells (Anemia).
• Fingers sticking together (fused fingers or toes).
• Deformed and/or thickened fingernails and toenails.
• The appearance of small white blister-like bumps (milia) on the skin.
• Difficulty swallowing food (dysphagia).
• Lack of expected growth in a child.
• Teeth not developing as expected ( hypoplasia ).

What causes EB?

The main cause of EB is a mutation or defect in one of 18 genes . People with this disease have a missing or damaged gene that helps make a protein called collagen . As you know, collagen is what gives strength and structure to connective tissues like our skin. So, because of this gene defect, the two layers of the skin, the epidermis and the dermis, don't connect together normally. As a result, the skin becomes very fragile, easily blistered, and injured.

EB is often an inherited disease , meaning that if one of the parents has it, the children can inherit it.

However, very rarely, EB can also occur as an acquired autoimmune disorder .

The most important thing is that EB is not a contagious disease. It is usually hereditary. So, if you are in contact with someone who has EB, you will not get it.

How do you know for sure if you have EB? (Diagnosis)

Doctors can diagnose EB by performing a skin biopsy , which involves a doctor taking a small sample of skin and examining it under a microscope.

In addition, genetic testing can identify the defective gene and confirm the EB type. Parents who are planning to have a child can also undergo prenatal genetic testing to find out if they are at risk of having a child with EB.

What are the treatments for EB?

Unfortunately, there is currently no cure for EB . However, treatments can help:

• Helps prevent blisters.
• Taking good care of the blisters and skin prevents complications.
• Treats nutritional problems that may be caused by blisters in the mouth or throat.
• Controlling pain.

To prevent skin damage and the formation of blisters and sores due to friction, doctors recommend the following:

• Wear soft, loose-fitting clothes made from natural fibers. Wearing clothes inside out can help reduce the amount of seams rubbing against your skin.
• Avoid overheating; keep rooms at a comfortable, consistent temperature.
• Avoid going out in the sun, or wear sunscreen while using sunglasses and hats.
• Use special types of bandages to protect the skin – use nonadhesive bandages and tape, rolled gauze, etc.

To treat blisters, your doctor may recommend things like:

• Apply ointments to wounds every day.
• Use medicated bandages to help blisters heal and prevent infection.
• Take medication to control the pain.

To treat infections, your doctor may recommend the following:

• Take oral antibiotics or apply an antibiotic cream.
• Use special wound coverings for wounds that do not heal.

To prevent nutritional problems and difficulty eating due to mouth or throat blisters, your doctor may recommend the following:

• When feeding your baby, use a baby bottle with a special nipple .
• Feed the baby with an eyedropper or a syringe.
• Add a little water to mashed foods to dilute them before feeding. This will make them easier to swallow.
• Eat more soft foods like soup, mashed foods, pudding, and applesauce .
• Food is served at a warm (not too hot) temperature.
• See a dietitian to discuss your specific nutritional needs.

In severe cases of EB, you may also need surgery . If the esophagus (the tube that carries food from the mouth to the stomach) is blocked by blisters and scarring, surgery may be done to widen it. Some people may be able to bypass the esophagus entirely and have a feeding tube inserted to feed food directly into the stomach. Surgery may also be done to separate fingers that are stuck together because of the blisters.

How does someone with EB take care of themselves?

If you have EB, these tips will help you take care of yourself:

• Sleep on sheets and pillowcases made from soft, natural fibers, such as silk or satin.
• Wear comfortable shoes that don't constrict your body.
• Avoid standing or walking for long periods of time.
• Avoid scratching or picking at the skin. Apply anti-itch medications to reduce itching.
• Be aware of your surroundings and avoid accidentally touching or scratching your skin.
• Always moisturize your skin to reduce friction.
• If blisters develop, pop them quickly with a sterilized needle or clean scissors.
• Use a nonadhesive bandage. Alternatively, apply petroleum jelly (Vaseline™) or a skin-friendly ointment (such as Aquaphor™) to the bandage to prevent it from sticking to the skin.

How to care for a child with EB? Some tips for parents

If your child has EB, their needs are different from others. They may not be able to communicate their discomfort. These tips can help keep your child as comfortable as possible:

• Wash your hands thoroughly before touching your baby's skin.
• Avoid using latex gloves, as they can increase friction.
• When bathing your baby, instead of putting the entire body in a basin filled with water at once, bathe each section of the skin one at a time.
• Instead of putting your newborn in diapers, consider putting absorbent pads on them.
• Use diapers with Velcro® straps. Adhesive straps/tape can inadvertently stick to your baby's skin.
• Cut and remove the elastic where the legs of the diaper are attached.
• Place something like silicone gel sheets on the inside of the diaper to prevent the skin from sticking to the blisters that have formed.
• Be very careful when lifting your child. Avoid lifting by placing your hands under the armpits (axilla). If your child has blisters or wounds on their thighs and back, lift them with one arm around their thighs and the other arm supporting their back.
• Encourage your child to be as active as their EB condition allows. Sitting still can lead to other complications, such as constipation and muscle atrophy . Swimming is a good, low-impact exercise.
• Do not encourage strenuous physical activities or games that will make your child sweat or get hot.

Dealing with your child's symptoms can be difficult at times. You may feel overwhelmed and exhausted. Ask your doctor for more tips to keep your child – and you – as comfortable as possible. Also, by joining parent support groups , you can share your experiences and learn new ways to manage your child's EB condition.

Can EB be prevented?

Because EB is genetic, it cannot be prevented . People who have a family history of EB and are planning to have children may find genetic counseling to be very helpful in deciding how to plan their family.

Additionally, experts currently don't know what causes the acquired form of EB. Therefore, doctors don't know how to prevent it.

What kind of future can someone with EB expect?

The future of people with EB depends on the type of EB they have and its severity. Severe forms of the disease can cause severe pain, deformities, disabilities, wounds that never heal, and even early death .

However, doctors can help you manage your symptoms. This can be done with proper treatment and, if necessary, pain medication. Keeping the skin well covered with nonadhesive, protective dressings every other day, bathing frequently, and wound care can help reduce the impact of EB on your life.

If you have EB, when should you see a doctor?

Be sure to see your doctor in these cases:

• If you have difficulty breathing.
• If you have difficulty swallowing food.
• If your wound looks infected (skin turning red, purple, gray, or white; inflamed or swollen).
• If new symptoms appear.

What are the important questions to ask the doctor?

When you go to see a doctor, it's a good idea to ask questions like these:

• How can you tell if I have EB?
• If I don't have EB, what other skin disease could I have?
• How can I manage my symptoms?
• What medications do you recommend? Do they have side effects?
• What home treatments do you recommend?
• What else should I do to improve my symptoms?
• Is there a cream or ointment you can prescribe?
• Should I see a dermatologist or another specialist?

What is the difference between epidermolysis bullosa (EB) and bullous pemphigoid?

Bullous pemphigoid is a rare, autoimmune skin disease. It can cause itchy, hive-like welts or fluid-filled blisters. Bullous pemphigoid most often affects people over the age of 60 , and it usually goes away within five years. However, in severe cases, the blisters and scarring can damage internal organs and be fatal.

Although EB can sometimes be an autoimmune disease, it is usually caused by a genetic mutation that affects the collagen in your skin. EB usually appears in infancy or early childhood . Since there is no cure for EB, you may have to live with symptoms for the rest of your life.

Finally, things to remember (Take-Home Message)

Epidermolysis bullosa (EB) is a challenging condition at times. However, with proper medical advice, treatment, and loving care, you can manage the symptoms and live as well as possible. Remember, you are not alone. Doctors, family, and support groups are all there to help you. So, don't be afraid, stay strong, and face this situation.

If you have any further questions about EB, be sure to talk to a dermatologist.
