Meta-analysis concurs occurrence of lower serum 25(OH)D levels in atopic dermatitis


 

Key clinical point: Patients with atopic dermatitis (AD) vs. healthy controls had significantly lower levels of serum 25-hydroxyvitamin D (25[OH]D), with the levels even lower in patients with severe vs. mild/moderate AD. Supplementation with vitamin D helped improve AD symptoms.

Major finding: The mean serum 25(OH)D level was significantly lower by 7.42 ng/mL in patients with AD vs. healthy controls and by an average of 7.99 ng/mL and 2.95 ng/mL in patients with severe vs. mild and moderate AD, respectively (all P < .001). Over a weighted mean of 2.88 months, patients receiving vitamin D supplementation at a weighted mean dose of 1,721 IU/day reported improvement in AD symptoms ( P < .001).

Study details: Findings are from a meta-analysis of 20 studies with 1,882 cases of AD.

Disclosures: This study did not receive any funding. The authors declared no conflict of interests.
