Causes of dermatitis herpetiformis
Despite its name, the herpes virus doesn’t cause dermatitis herpetiformis. If you have celiac disease and eat gluten, your intestines make an antibody called IgA in response. This chemical flows into your bloodstream and builds up in blood vessels under your skin. It triggers the DH rash.
In celiac disease, gluten causes intestinal inflammation resulting in diarrhea, tiredness, weight loss and abdominal discomfort.
Dermatitis herpetiformis predominantly affects Caucasians aged 15–40 years but may occur in those younger or older and in other races.
Men commonly get it more often than women.
More females under the age of 20 are affected than males.
Some group people who have autoimmune diseases like autoimmune thyroid disease, type 1 diabetes, Sjogren syndrome, and lupus are prone to get dermatitis herpetiformis.
Symptoms of dermatitis herpetiformis
Dermatitis herpetiformis looks like a cluster of itchy bumps that can be easily confused with acne or eczema. Blisters can also form, and you could be misdiagnosed with herpes.
Dermatitis herpetiformis commonly occurs on the body area include knees, elbows, buttocks and hairline.
Dermatitis herpetiformis is not contagious.
You may also have oral tooth enamel problems like pitting, discoloration, horizontal grooves, and rarely canker sores.
Gastrointestinal problems also may present because of celiac disease. these symptoms include bloating, cramping, diarrhea, constipation and pain.
Can dermatitis herpetiformis be misdiagnosed?
Sometimes dermatitis herpetiformis is mistaken for herpes, scabies, papular urticaria and other types of dermatitis. Your healthcare professional may need to test your skin to determine an accurate diagnosis.
Treatment options for dermatitis herpetiformis
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
Usually, dermatitis herpetiformis is treated with a gluten-free diet and an oral antibiotic called dapsone. If dapsone doesn’t help, your healthcare provider may prescribe sulfapyridine or sulfasalazine.
A strict gluten-free diet is effective for both dermatitis herpetiformis and the associated gastrointestinal manifestations.
topical corticosteroids may be used short-term to lessen the intensity of the itching, but do not suffice as a long-term treatment.
Patients are usually managed by a dermatologist for the management of dermatitis herpetiformis and a nutritionist for dietary counseling.
