Vitamin D Supplementation for Severe Atopic Dermatitis
Symptoms Studied
Chronic inflammatory skin condition with intense itching, dry scaly patches, redness, and skin barrier dysfunction. Symptoms often worse in winter and can significantly affect quality of life.
Research Hypothesis
Vitamin D has immunomodulatory effects and supports skin barrier function. Supplementation may reduce inflammation and improve atopic dermatitis severity.
Intervention Tested
Vitamin D3 (Cholecalciferol)
1600 IU vitamin D3 daily, taken orally, as adjunct to topical hydrocortisone cream
Study Results
Before Treatment
Children with severe atopic dermatitis as measured by EASI score, with inadequate response to topical treatments alone.
After Treatment
Mean EASI (Eczema Area and Severity Index) score was significantly lower in vitamin D group compared to placebo (p=0.035). Meta-analysis shows vitamin D reduces AD severity.
Timeline to Improvement
Improvements observed within 4-8 weeks with continued benefit through 12 weeks
Side Effects
Well-tolerated at recommended doses. No hypercalcemia or significant adverse events reported.
