Dermatitis herpetiformis is an extremely itchy rash consisting of bumps and blisters. The rash is chronic, which means it continues over a long period. Dermatitis herpetiformis usually begins in people age 20 and older. Children can sometimes be affected. It is seen in both men and women. The cause is unknown. It is thought to be an autoimmune disorder. Dermatitis herpetiformis is also linked to gluten sensitivity (celiac sprue disease) in the small bowel. Symptoms of dermatitis herpetiformis tend to come and go. Symptoms include: extremely itchy bumps or blisters, most often on the elbows, knees, back, and buttocks. The rash is usually the same size and shape on both sides. The rash can look like eczema. Some patients may have scratch marks instead of blisters. A strict gluten-free diet will be recommended to help control the disease. Sticking to this diet may eliminate the need for medications and prevent later complications. The disease may be well-controlled with treatment. Without treatment, there may be a significant risk of intestinal cancer.[rx]
Types of Dermatitis Herpetiformis:
Dermatitis herpetiformis mainly presents in one form:
- Classic Dermatitis Herpetiformis: This is the most common type, characterized by itchy, blistering skin rashes.
Causes of Dermatitis Herpetiformis
DH is closely related to celiac disease, which is an autoimmune disorder triggered by gluten consumption. Here are some common causes:
- Gluten Sensitivity: Eating foods containing gluten, like wheat, barley, and rye, can trigger DH in people with gluten sensitivity.
- Celiac Disease: DH is often a skin manifestation of celiac disease.
- Genetics: DH can run in families due to genetic factors.
- Immune System Reaction: It occurs when the immune system mistakenly targets the skin when exposed to gluten.
- Stress: Stress can worsen DH symptoms.
- Infections: Infections can sometimes trigger DH.
- Medications: Certain medications can exacerbate or trigger DH in some individuals.
- Hormonal Changes: Hormonal fluctuations may impact DH severity.
- Menopause: Women going through menopause may experience DH symptoms.
- Pregnancy: DH can be affected by pregnancy in some cases.
- Thyroid Disorders: Thyroid issues may be linked to DH.
- Liver Disorders: Liver conditions can contribute to DH development.
- Vitamin Deficiencies: Low levels of certain vitamins may play a role in DH.
- Strenuous Exercise: Intense physical activity can sometimes worsen DH.
- Alcohol Consumption: Alcohol may exacerbate DH symptoms in some individuals.
- Injury or Trauma: Skin injuries or trauma can trigger DH eruptions.
- Menstrual Cycle: Hormonal changes during menstruation may affect DH.
- Menstrual Pain Relievers: Some pain relievers used during menstruation may affect DH.
- Insect Bites: Insect bites can sometimes worsen DH rashes.
- Surgery: Surgery and anesthesia may trigger DH in rare cases.
