February 6, 2014 updated by: Montree Udompataikul, Srinakharinwirot University

Background: Increase in skin colonization of Staphylococcus aureus (S. aureus) in atopic dermatitis patients (AD) resulted from the reduction of cathelicidin production in these patients plays the important role in pathogenesis of this disease. Recently in vivo study has showed that vitamin D can stimulate cathelicidin production. Oral supplement of vitamin D might be beneficial in atopic dermatitis.

Objective: To determine the effect of oral vitamin D supplement on clinical impact including skin colonization of S. aureus in atopic dermatitis patients.

Patients who used topical antiseptic or antibiotic products during study period were also excluded. Patients who developed worsening of AD with flare-up of clinical manifestation or SCORAD greater than 40, secondary infection on-top tested lesions were excluded from data analysis.
