Epidermolysis Bullosa Simplex: Causes, Symptoms, and Treatment

What kind of doctor treats Epidermolysis Bullosa Simplex?
A dermatologist, a doctor who treats skin, hair, and nail conditions, usually treats epidermolysis bullosa simplex. A clinical geneticist, a doctor who diagnoses genetic disorders, may also help. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is epidermolysis bullosa simplex?
Epidermolysis bullosa simplex (EBS) is one of a group of genetic conditions called epidermolysis bullosa. These conditions make the skin very fragile and quick to blister. Blisters and erosions (areas of skin loss) form after rubbing, scratching, or other minor injury.
In EBS, the blisters form in the lower part of the epidermis, which is the top layer of skin. EBS is the most common form of epidermolysis bullosa.
Experts estimate that EBS affects 1 in 30,000 to 50,000 people.
Symptoms
Signs and symptoms vary widely from person to person.
In mild cases, blisters mostly affect the hands and feet and usually heal without scars. Later in life, the skin on the palms and soles may thicken and harden.
Severe cases involve widespread blistering. This can lead to infections, dehydration, and other medical problems. Severe cases may be life-threatening in infancy.
EBS has four major types:
- The localized type is the mildest. Blistering is usually limited to the hands and feet.
- The Dowling-Meara type is the most severe. Blisters can appear anywhere, including inside the mouth, and may form in clusters. They are present from birth and tend to improve with age.
- The other generalized type causes widespread blisters at birth or in early infancy. They are usually less severe than in the Dowling-Meara type.
- The type with mottled pigmentation causes patches of darker skin on the trunk, arms, and legs. The patches fade in adulthood.
Depending on the type, other symptoms can include:
- Thickened skin on the palms of the hands and soles of the feet.
- Rough, thickened, or absent fingernails or toenails.
- Blisters inside the mouth.
Causes and who gets it
EBS is usually caused by changes in the KRT5 or KRT14 gene. These genes make keratin proteins, which give the outer layer of skin its strength. When the genes are changed, the proteins cannot form strong networks. The skin cells become fragile and easily damaged.
EBS is usually inherited in an autosomal dominant pattern. This means one changed copy of the gene is enough to cause the disorder. Some people get it from an affected parent. Others have a new gene change and no family history. In rare cases, EBS is inherited in an autosomal recessive pattern.
With a dominant gene change, a person has a 50% chance of passing the disorder to each child.
Epidermolysis bullosa affects males and females equally. It occurs in all racial and ethnic groups.
How doctors diagnose it
Doctors start by asking about family and medical history. They examine the skin closely. They may take a skin biopsy, a small skin sample studied under a microscope. It shows which skin layers are affected.
Genetic testing can find the exact gene change and help diagnose the type. After genetic testing, see a specialist or genetic counselor to help you understand the results.
Treatment
There is no cure for epidermolysis bullosa. A gene therapy for wounds was approved only for dystrophic epidermolysis bullosa, a different type.
Treatment aims to control symptoms. The goals are to manage pain and itch, protect the skin, prevent infection, keep moving, and eat well.
Doctors may recommend pain medicine for blisters and open wounds. Use non-adhesive bandages when possible. If a bandage sticks, soaking the area in warm water may help loosen it. Doctors may prescribe antibiotics for infected wounds.
A physical or occupational therapist can help with movement. A dietitian can help if blisters make eating hard.
Daily habits can lower friction and blistering. Keep your skin cool and wear loose, soft clothing. Avoid overheating. Lotions, creams, or ointments can reduce friction and keep skin moist.
When to see a doctor
See a doctor if your skin or your child's skin blisters easily after rubbing or minor injury.
Contact your doctor right away if a wound has increased redness, more pain, red streaks, pus, or fever.
Call 911 or go to the emergency room if you or your child has trouble or abnormal breathing, bluish or grey skin, fainting, or a sudden change in mental state.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can help with early evaluation and ongoing skin checks. They can also help coordinate visits with a dermatologist, a geneticist, therapists, and a dietitian.
Common questions
Is EBS inherited?
Usually, yes. Some people inherit it from an affected parent, and others have a new gene change with no family history.
Does EBS cause scars?
It depends on severity. In mild cases, blisters usually heal without scars.
Is there a cure for EBS?
No, there is no cure for epidermolysis bullosa. Treatment focuses on managing pain, protecting the skin, and preventing infection.
Does EBS get better with age?
In some types, yes. In the Dowling-Meara type, blistering is present from birth and tends to improve with age.
