Atopic Dermatitis

Keywords
Cetoleic acid, LC-MUFA, Ezcema, Nutritional study
Brief summary
Atopic Dermatitis is associated with pronounced changes in the lipid composition in the skin. The lipid changes are influenced by and contributing to both the inflammatory circuit and the impaired barrier as well as changes in the skin microbiome This nutritional study will investigate the effect of long-chain monounsaturated fatty acid Cetoleic acid on atoptic dermatitis. Earlier studies have shown a anti-inflammatory effect of celoteic acid.
Detailed description
Women and men will be recruited to a placebo or a cetoleic-rich fish oil group and be examined for the effect on atopic dermatitis before, during and after the study period.
Interventions
2 x 1 g capsules containing marine oil from North Atlantic fish
2 x 1 g capsules containing corn oil
Sponsors
Study design
Masking description
Interventions are given as 1g bovine capsules of equal size, weight and appearance, and provided in identical bottles with a coded label.
