Medicines for Epidermolysis bullosa

What it is

Epidermolysis bullosa (EB) is the name for a group of rare, inherited conditions that make the skin (and sometimes the linings inside the body) very fragile, so that it blisters and tears very easily — often from minor friction, rubbing, knocks, or even everyday handling that would not harm normal skin. It is caused by genetic changes affecting the proteins that normally hold the layers of the skin together, so the skin does not bind properly and comes apart easily, forming blisters and wounds. EB is usually present from birth or early childhood, and is lifelong. There are several main types, which vary greatly in severity — from milder forms, where blistering is more limited (for example to the hands and feet) and the impact is less, to severe forms, where widespread, painful blistering and wounds affect large areas of skin and can also affect the mouth, digestive tract, eyes, and other areas, with significant effects on health, nutrition, and daily life. In severe forms, the repeated blistering, wounds, scarring, and complications can be very challenging, and EB can be a serious, complex condition needing extensive specialist care. Because the skin is so fragile, the mainstays of care are protecting the skin from damage, careful wound care and dressing of blisters and wounds, managing pain and itching, preventing and treating infection, and supporting nutrition and the various aspects of health that can be affected — all tailored to the type and severity, and coordinated by specialist EB services and multidisciplinary teams. There is currently no cure for EB, and care is focused on managing the condition, protecting the skin, healing and preventing wounds, managing complications, and supporting the person and family; research into new treatments is ongoing. The key messages are that EB is a group of rare inherited conditions causing extremely fragile skin that blisters and tears easily, that severity varies greatly, and that careful skin protection, wound care, and specialist multidisciplinary support are the mainstays.

How it is treated

Epidermolysis bullosa is managed by specialist multidisciplinary teams, with care focused on protecting the fragile skin, careful wound care, managing pain and complications, and supporting the person and family; there is no cure, and management is tailored to the type and severity. Because the skin is so fragile, protecting it from damage is central: this includes gentle handling, avoiding friction and rubbing, using soft clothing and protective measures, and careful techniques for everyday activities and handling (particularly important for babies and children with EB) — specialist advice guides how to minimise skin damage. Careful wound and blister care is a major part of daily management: blisters may need to be safely drained (as advised) to stop them spreading, and wounds are cleaned and dressed with specialist, non-adherent dressings that protect the skin and wounds without sticking and causing further damage; good wound care promotes healing and reduces the risk of infection. Managing pain and itching is important, as EB can be painful and itchy, and effective pain and symptom management improves comfort and quality of life. Preventing and treating infection is important, as open wounds are prone to infection. For more severe forms, the multidisciplinary team addresses the many aspects that can be affected — for example, nutrition (as feeding and the digestive tract can be affected, and good nutrition supports healing and health), the mouth and teeth, the eyes, the hands (which can be affected by scarring), and other complications — and provides ongoing monitoring and care, including for the increased risk of certain skin cancers in some severe types over time. Care is coordinated by specialist EB centres and teams, who provide expertise, support, and continuity. Support for the person and family — practical, emotional, and social — is a vital part of care, given the challenges of living with EB, and support organisations provide information and community. Genetic counselling is offered to discuss inheritance and family planning. Research into new treatments, including approaches targeting the underlying genetic cause and improving wound healing, is ongoing and offers hope for the future. The reassuring messages, within the seriousness and challenge of EB (especially the severe forms), are that specialist multidisciplinary care focuses on protecting the skin, healing and preventing wounds, managing pain and complications, and supporting the person and family, that care is tailored to the individual, and that support and research offer help and hope; so specialist EB care and coordinated support are the keys to managing the condition.
