简要总结
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.
详细描述
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.
