Describe the pathogenesis of Dermatitis Herpetiformis
- Exposed to wheat
- gliadin
- in GI junction form antibody response
- these IgA don’t just stay in the intestine– they spread throughout the body creating inflammation – along w/neutrophils
- can also spread to the skin & depositing at the dermal/epidermal junction causing a blister to form
- causing the skin rash
- Associations
- Thyroid disease
- Lymphoma (T-cell)
- gluten-free diet
Diagnosis of Dermatitis Herpetiformis?
Treatment?
- Diagnosis
- Clinical
- Biopsy
- Intact lesion for histology
- skin adjacent to lesion for DIF
- IgA deposits
-
Antiendomysial antibodies
- sensitive & specific
- reflect severity of enteropathy and compliance of diet
-
Antigliadin antibodies
- also found in pemphingus & pemphigoid
- Treatment
- Dapsone
- control not clear
- can cause hemolysis (anemia)
- need to screen for G6P dehydrogenase deficiency
- Gluten-free diet
- barley rye, oats (contaminated) & wheat
- corn, rice & oats are okay
- Dapsone
