Summary
Malnutrition can cause skin issues, like pellagra (niacin deficiency) in anorexia nervosa patients. Self-imposed diets in adults with atopic dermatitis can also lead to severe nutritional deficiencies.
Area of Science:
- Dermatology
- Nutrition Science
- Internal Medicine
Background:
- Malnutrition is uncommon in the UK, but awareness of its dermatological manifestations and nutritional sequelae is growing.
- Two cases highlight the link between malnutrition, skin conditions, and dietary restrictions.
Observation:
- Case 1: Anorexia nervosa patient presented with pellagra, a niacin deficiency characterized by rash on sun-exposed areas.
- Case 2: Adult atopic dermatitis patient developed multiple nutritional deficiencies due to a self-imposed restrictive diet.
Findings:
- Pellagra, linked to niacin deficiency, rapidly improves with replacement therapy.
- Restrictive diets in adult atopics, though uncommon in the UK, can cause significant nutritional deficiencies.
Implications:
- Healthcare providers should consider nutritional screening more frequently, especially in patients with eating disorders or restrictive diets.
- Recognizing dermatological signs of malnutrition is crucial for early diagnosis and intervention.
- Further research into the nutritional impact of restrictive diets in atopic individuals is warranted.
