A patient with dermatitis herpetiformis associated with celiac disease requires therapy; which two treatments are standard initial management?

• A. Dapsone
• B. Gluten-free diet
• C. Dapsone and gluten-free diet
• D. Prednisone

Answer: (C)

The key idea is that management combines rapid skin symptom relief with long-term control of the underlying gluten-sensitive disease. Dermatitis herpetiformis is a skin manifestation of celiac disease caused by IgA immune deposits at the dermal papillae; treating it effectively requires addressing both the rash and the intestinal trigger. Dapsone provides quick relief from itching and lesions by reducing neutrophil-driven inflammation in the skin. It acts fast, improving symptoms within days, but it doesn’t treat the underlying gluten sensitivity, so the rash can recur if gluten is ingested. A strict gluten-free diet tackles the root cause by removing the trigger that drives the immune response in celiac disease. Over time, this leads to healing of the intestinal mucosa and a reduction in new skin lesions. Therefore, starting both therapies together is the standard initial approach: dapsone for immediate cutaneous relief and a gluten-free diet for long-term control. Be mindful that dapsone can have side effects like hemolysis or methemoglobinemia, especially in G6PD deficiency, so monitoring is important.
