ABSTRACT
BACKGROUND: ß-thalassemia is an inherited disorder that stems from a defect in beta-globin chain synthesis. Iron overload toxicity is one of the major clinical complications in ß-thalassemia that may be due to a reduction in the hepcidin level. As a result, intestinal iron absorption increases and finally iron overload occurs. The current study aimed to investigate the effect of curcumin on serum iron status, ferritin, and transferrin in patients with ß-thalas-semia intermedia. METHODS: This study was a randomized, controlled, double-blind clinical trial. Before and after the intervention period with curcumin, 5 ml blood was taken for the measurement of the entire index related to iron status. RESULTS: Our results demonstrated the levels of serum iron (p-value < 0.001), ferritin (p-value = 0.002), and transferrin saturation (p-value < 0.001) significantly decreased in the curcumin group compared to placebo. CONCLUSIONS: The data presented in this article show that curcumin supplementation would be effective in alleviating iron overload in patients with ß-thalassemia intermedia.

Thalassemia intermedia is a subgroup of ß-thalassemia which originates from mutations in the beta-globin gene. Zinc and copper play important roles in the metabolism. Due to its significant therapeutic effects, curcumin has led many studies to focus on curcumin. In a double-blind clinical trial study, 30 patients with beta-thalassemia intermedia with an age range of 20 to 35 years were randomly selected 1:1 to receive either curcumin or placebo for 3 months. Before and after the intervention period, 5 ml of blood was taken to determine the serum levels of zinc and copper. The laboratory tests were checked at baseline and at the end of the treatment. While the serum levels of zinc and zinc/copper significantly increased, the serum levels of copper decreased after 3 months of curcumin intake. In addition, on the basis of baseline characteristics, a negative correlation was found between zinc and body mass index and positive correlations were identified between copper with triglyceride and high-density lipoprotein. Also, the level of ferritin protein in the curcumin group compared to the placebo group showed a significant decrease after 3 months of curcumin use. Therefore, it could be concluded that curcumin might exert a net protective effect on copper toxicity in thalassemia intermedia patients. The investigation also implicated that curcumin represents an approach to regulating zinc homeostasis and may be useful as a complementary treatment of patients with thalassemia intermedia, especially in patients with zinc deficiency or low serum zinc/copper ratio.
