Disease name : Epidermolysis bullosa ( EB ) , or " butterfly disease "
Affected populations : Butterfly disease is gauge to affectaround 1 in 50,000 shaver , if you consider all subtypes of the disease together . EB is evenly vulgar among males and females , as well as across races and ethnicities .
Epidermolysis bullosa, or “butterfly disease,” is a rare genetic disorder that causes patients to develop severe, painful blisters in response to friction.
Causes : Butterfly disease refer to a group of rare , inherited disease thatcause the skin to be very slight and to blister well . There arearound 30 subtypes of butterfly disease , and these are assort into four main groups that differ based on the part of the skin that is bear upon .
The most common form of the disease , which affect 70 % of EB patient , is know as epidermolysis bullosa simplex ( EBS ) . Patients with EBS carry genetic mutations that dissemble the outermostlayer of their skin , called the cuticle . EBS is normally an autosomal dominant disorder , intend that children who inherit just one copy of the mutant factor from a parent will develop it . seldom , the diseasepasses in an autosomal recessive pattern , in which a nipper call for two copies of the cistron — one from each parent — to develop it .

Butterfly disease affects different parts of the skin, depending on the subtype of the condition.
Symptoms : Patients usually begin to develop symptoms of butterfly diseaseat birth or during early childhood . symptom can vary from meek to severe , and they dissent across the subtypes of the disease . Common , worldwide symptoms of EB admit havingskin that blisters easy , especially on the hands and colloidal suspension of the feet . These areas of the body also often have thickened , scarred skin . Mild forms of butterfly stroke diseasecan meliorate with ageandaren’t fateful , but patients with severe forms typically do n’t exist beyond years 30 . That ’s because severe face can run to life - threatening contagion and damage internal organs .
discourse : There is currentlyno cure for butterfly disease . However , appropriate wound care — for instance , draining blisters and using nonadhesive bandages and dressings to cover wound — can help oneself patients make do their symptoms . drug can also be taken torelieve the itch and painassociated with the bleb , and antibiotics can treat any related to bacterial infections . Some patientsmay also require surgeryif the disease causes their esophagus to constrict or if they have problem using their hands due to exuberant scarring .

In 2023 , the U.S. Food and Drug Administration ( FDA ) approveda new factor therapy gelfor the treatment of a specific character of butterfly disease in patient role who are at least 6 months old . Called dystrophic epidermolysis bullosa , this form of the disease is due to mutations in a gene that codes for a character of collagen in the skin . The gene therapy , known as Vyjuvek , delivers turn copies of the collagen gene into patients ' cells .
This same gene therapy was also adapted into eye drops in 2023 . It was used to helprestore the visual modality of a teenaged boywho was legally blind due to pit of the eye because of butterfly disease .
The FDA has also approvedanother gel , called Filsuvez , for the treatment of wounds in patients 6 months and older . The gel , made from birch bark , is approved for only certain types of butterfly disease .
