Dystrophic Epidermolysis Bullosa: Causes, Symptoms, and Treatment

What kind of doctor treats Dystrophic Epidermolysis Bullosa?
A dermatologist, a doctor who treats skin conditions, usually leads care for dystrophic epidermolysis bullosa. A clinical geneticist, a doctor who diagnoses inherited conditions, and a pediatrician, a children's doctor, 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 dystrophic epidermolysis bullosa?
Dystrophic epidermolysis bullosa, or DEB, is one of the major forms of epidermolysis bullosa. In these conditions, the skin is very fragile and blisters easily. Blisters and sores form after minor injury or friction, such as rubbing or scratching.
DEB varies widely from person to person. In mild cases, blisters may mostly affect the hands, feet, knees, and elbows. Severe cases can involve blisters over much of the body. These can lead to vision loss, scarring, and other serious problems. The two main types are recessive and dominant.
Symptoms
The most severe form is severe generalized recessive DEB. Babies are usually born with widespread blisters and areas of missing skin. Blisters can also form on mucous membranes, the moist lining of the mouth and digestive tract. Problems can include:
- Scarring in the mouth and esophagus, the tube from the throat to the stomach. This can make chewing and swallowing hard and lead to slow growth.
- Skin fusing between the fingers and toes.
- Loss of fingernails and toenails.
- Contractures, which are tight joints that limit movement.
- Eye inflammation that can lead to vision loss.
- A very high risk of a skin cancer called squamous cell carcinoma in young adulthood.
In mild cases, blistering is often limited to the hands, feet, knees, and elbows. Dominant DEB tends to be milder. Most affected people have malformed fingernails and toenails. Blood loss from wounds can lead to anemia, a shortage of healthy red blood cells.
Causes and who gets it
Changes in the COL7A1 gene cause all forms of DEB. This gene helps make type VII collagen, a protein that anchors the top layer of skin to the layer under it. When this protein is missing or faulty, friction can make the two layers separate. That causes blisters.
Recessive DEB means both copies of the gene have changes. The parents usually each carry one changed copy and have no symptoms. Dominant DEB needs only one changed copy. About 70 percent of people with dominant DEB inherit it from an affected parent. The other 30 percent have a new change in the gene.
How doctors diagnose it
Doctors usually ask about family and medical history and examine the skin. They also do a skin biopsy, which means checking a small skin sample under a microscope. Genetic testing can show which gene changes a person has and the exact type of the disease. People who have genetic testing should see a specialist or genetic counselor to understand the results.
Treatment
There is no cure for epidermolysis bullosa. Treatment aims to control pain and itch, protect the skin and care for wounds, prevent infection, keep movement, and keep nutrition good.
The FDA has approved treatments for wounds in DEB. One is a gene therapy applied to wounds by a medical professional once a week. Side effects in the trial included itching, chills, rash, cough, and a runny nose. People who are pregnant should avoid direct contact with it and with treated wounds. Another is a skin graft for recessive DEB made from the person's own skin cells. It needs surgery, and the most common side effects were pain and itching.
Other care can help. Physical and occupational therapists help keep movement. A dietitian can suggest soft foods. Surgery can widen a narrowed esophagus, place a feeding tube, or release fused fingers or toes.
When to see a doctor
Contact your doctor right away if you see signs of infection. These include more redness, more pain in a skin sore, red streaks coming from a wound, pus, or fevers.
Skin cancer can develop in areas with long-standing wounds and scars. Tell your doctor about any wound that does not heal. Surgery is often the most effective way to remove skin cancer.
Call 911 or go to the emergency room for bleeding that will not stop, choking, trouble breathing, or fainting. Severe epidermolysis bullosa can be life-threatening because of widespread blistering, infections, and loss of body fluid.
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. Either kind of doctor can help with day-to-day wound questions and watch for signs of infection. They can also help coordinate skin, genetics, nutrition, and therapy specialists.
Common questions
Can dystrophic epidermolysis bullosa be cured?
No, there is no cure for epidermolysis bullosa. Treatment focuses on controlling symptoms and protecting the skin. The FDA has approved some treatments that help wounds heal.
Is dystrophic epidermolysis bullosa inherited?
Yes, it is caused by changes in the COL7A1 gene. Recessive DEB needs changes in both copies of the gene. Dominant DEB needs only one, and about 30 percent of those cases are a new change.
Is dystrophic epidermolysis bullosa life threatening?
It can be, in severe cases. Severe epidermolysis bullosa can be life-threatening because of widespread blistering, infections, and loss of body fluid.
How can people with dystrophic epidermolysis bullosa protect their skin?
They can keep the skin cool, wear loose and soft clothing, and avoid overheating. Lotions, creams, or ointments can reduce friction and keep skin moist.
