简要总结
This interventional, double-blind, randomized, placebo-controlled study aims to evaluate the effect of a marine by-product hydrolysate supplementation on the reduction of atopic dermatitis symptoms.
详细描述
The study will be carried out with 108 subjects divided in 3 groups of 36 subjects who will be supplemented with two dosages of the food supplement or a placebo.
This study intends to assess objectively and subjectively the efficacy of a food supplement claimed to improve the skin condition related to atopic dermatitis. The objectives of the study consist in the evaluation of the supplementation to improve the skin condition and symptoms on atopic dermatitis (by SCORAD), to reduce the eczema and severity on atopic dermatitis (by SCORAD and Eczema Area and Severity Index), to reduce the inflammatory signs (by Investigator Global Assessment scale), to moisturize and to improve/maintain the skin barrier.
