|Patients with atopic dermatitis have an immune system defect that results in a deficiency of cathelicidin, one of the body’s own anti-infection peptides.
Dr. Richard Gallo, Dr. Tissa R. Hata, and colleagues have found cathelicidin levels increase in patients who receive daily Vitamin D3 (cholecalciferol).
The study is part of the Dermatology Division’s ongoing investigation of the role of the immune system in dermatologic disease.
Ten to twenty percent of children and 1-3% of adults suffer from atopic dermatitis, a chronic skin disorder that causes itching, redness, and scaling. Affected individuals are more vulnerable to skin infections including Staph aureus and herpes.
