DHA and EPA in Sickle Cell Disease Favor Clinical Improvement and Contribute to Better Quality of Life: A Qualitative Systematic Review
Abstract
BACKGROUND: Sickle cell disease is a severe genetic disorder, and searching for therapeutic strategies is indispensable for prolonged and improved life for people affected by this condition.
OBJECTIVES: This qualitative systematic review aimed to highlight the therapeutic potential of omega- 3 (n-3) in people with sickle cell disease.
METHODS: The search was performed by combining sickle cell disease and n-3 descriptors in DeCS/ MeSH databases, including Scopus, PubMed, ScienceDirect, Web of Science, and Virtual Health Library. The risk of bias assessment in the primary studies was performed using the Cochrane risk of bias tool for randomized controlled trials. The evidence quality was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.
RESULTS: From the 187 records identified, seven were selected for data collection. Based on the evidence, n-3 supplementation contributes to lower activation of pro-inflammatory biomarkers, improves the concentration of docosahexaenoic and eicosapentaenoic acids in the erythrocyte membrane, provides better hemostatic response, and helps in vaso-occlusive crisis, pain episodes, and hospitalization reduction.
CONCLUSION: The findings suggest that n-3 adjuvant therapy favors the clinical and general aspects of people with sickle cell disease.
