Dermatitis Herpetiformis (DH) is a chronic skin condition that causes a severe, itchy skin rash. It is also known as Duhring's disease. People with DH can experience a wide range of symptoms, including redness, itching, and burning of the skin. The rash typically appears on the elbows, knees, and buttocks, but can occur anywhere on the body. In some cases, the rash can spread to the scalp, face, and even the genitals.
DH is caused by an autoimmune disorder, meaning the body's immune system mistakenly attacks its own tissues. It is related to celiac disease, an autoimmune disorder that affects the digestive system. People with DH may also have an increased risk of other autoimmune diseases, including thyroid disease and Type 1 diabetes.
The exact cause of DH is unknown. It is thought to be triggered by gluten, a protein found in wheat, rye, and barley. People with DH should avoid eating foods containing gluten, as this can worsen the symptoms.
Treatment for DH typically involves taking a medication known as dapsone, which helps to reduce inflammation and relieve itching. Other medications, such as corticosteroids, can also be used to reduce inflammation and reduce the severity of the rash. In some cases, a gluten-free diet can help to improve symptoms.
DH is a lifelong condition that can cause significant discomfort and embarrassment. If you think you may have DH, it is important to talk to your doctor right away to get the diagnosis and treatment you need.
