ABSTRACT
AIM: Low levels of immune-related micronutrients have been identified in ß-thalassemia samples. Moreover, the excess amount of iron, contributing to oxidative stress in the pathogenesis of the disease, alters the immune system in ß-thalassemia, which is important during the COVID-19 pandemic. MATERIALS & METHODS: Searches of PUBMED and EMBASE were conducted to identify the level and supplementation of micronutrients in ß-thalassemia, published from 2001-May 2020. RESULTS: The review found six observational and five interventional studies supporting the importance of supplementing vitamins and minerals among patients with ß-thalassemia. CONCLUSION: Supplementation of immune-related vitamins and minerals might bring benefits to the immune system, especially in reducing oxidative stress in ß-thalassemia.
