Selenium, glutathione-peroxidase and dermatitis herpetiformis

Area of Science:

• Biochemistry
• Dermatology
• Nutritional Science

Background:

• Dermatitis herpetiformis is an autoimmune blistering skin disease.
• Glutathione-peroxidase is a key antioxidant enzyme.
• Selenium and vitamin E are important antioxidants.

Purpose of the Study:

• To investigate the effect of selenium and vitamin E supplementation on glutathione-peroxidase levels in patients with dermatitis herpetiformis.
• To assess the clinical efficacy of selenium and vitamin E in treating dermatitis herpetiformis.

Main Methods:

• A double-blind study design was employed.
• Patients received selenium and vitamin E treatment for 5 months.
• Blood glutathione-peroxidase levels were measured before and after treatment.
• Clinical assessment of dermatitis herpetiformis was performed.

Main Results:

• Blood glutathione-peroxidase levels significantly increased after 5 months of selenium and vitamin E treatment.
• No significant clinical improvement in dermatitis herpetiformis was observed despite increased glutathione-peroxidase levels.

Conclusions:

• Selenium and vitamin E supplementation can enhance antioxidant enzyme activity in dermatitis herpetiformis patients.
• Increased glutathione-peroxidase levels do not necessarily correlate with clinical improvement in this condition.
• Further research is needed to explore the therapeutic potential of antioxidants in dermatitis herpetiformis.
