The effect of fatty acids, vitamins, and minerals on pediatric atopic dermatitis: A systematic review

摘要

Abstract Background A body of research has examined the role of fatty acid (FA), vitamin, and mineral supplementation as adjunctive treatment for atopic dermatitis (AD); however, results are conflicting and concrete recommendations are lacking. The objective of this study is to highlight the role of these nutrients in alleviating AD severity and provide the clinician with consolidated information that can be used to make recommendations to the pediatric patient and caretaker, where this topic is of high interest. Methods A review of the PubMed and Embase databases was conducted to identify and qualitatively analyze all randomized controlled trials, systematic reviews, and meta‐analyses conducted within the last 21?years regarding use of these nutrients to alleviate symptoms of AD. Inclusion criteria include AD diagnosis, non‐infant age groups, and AD severity outcomes; exclusion criteria include preventative studies, predominantly maternal or infant demographics, or nonclinical outcomes. Results Sixty‐nine studies were included. Evidence regarding FA supplementation is inconclusive; however, targeting an ideal omega‐3:omega‐6 FA ratio may play a small role in alleviating AD symptoms. Studies results regarding vitamin/mineral supplementation are inconsistent and supplementation should not be advised unless the patient has a documented deficiency. Conclusion Pediatric AD patients should lead a healthy lifestyle with an emphasis on consumption of wholesome foods. Nutritional supplementation can play a role in improving AD symptoms; however, this should be evaluated on a case‐by‐case basis. Limitations include heterogeneity of studies.
