Effects of Curcumin on Iron Overload in Rats

Abstract

Background: Iron overload, common in patients with hematological disorders, is a key target in drug development. This study investigated the effects of curcumin on iron overload in rats.
 Methods: Forty male Wistar rats weighing 139.78 ± 11.95 gm (Mean ± SD) were divided into three equal groups: (i) controls; (ii) iron overload group that received six doses of iron dextran 1000 mg/kg–1 by intraperitoneal injections (i.p.); and (iii) iron overload curcumin group that received six doses of curcumin (1000 mg/kg BW by i.p.). In addition to six doses of iron dextran 1000 mg/kg–1 by i.p., we studied the effects of curcumin on liver function enzymes (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]); antioxidant enzymes (malondialdehyde [MDA], total oxidant status [TOS], total antioxidant status [TAS]); hematological parameters (hemoglobin [Hb], hematocrit [Hct], red blood cells [RBC], white blood cells [WBC], mean corpus volume [MCV], mean corpuscular hemoglobin [MCH], mean corpuscular hemoglobin concentration [MCHC]); and iron parameters (serum iron profile, transferrin, total iron-binding capacity [TIBC], ferritin, and transferrin saturation [TS%]).
 Results: Curcumin caused a significant decrease in the Hct and Hb concentrations in Group III (P < 0.05). It also significantly reduced the serum levels of ALT (52.45 ± 4.51 vs 89.58 ± 4.65 U/L) and AST (148.03 ± 6.47 vs 265.27 ± 13.02 U/L) at the end of the study (P < 0.05). The TIBC, transferrin levels, and TS significantly decreased when the rats were administered curcumin serum iron (P < 0.05). The TAS level significantly increased in Group III in comparison to Group I (the control group) (P < 0.05). At the end of the study, curcumin significantly reduced the serum levels of TOS (12.03 ± 2.8 vs 16.95 ± 5.05 mmol H2O2/L) while the TAS (1.98 ± 0.42 vs 1.06 ± 0.33 mmol Trolox equiv./L) was increased.
 Conclusion: The findings of the present study suggest the therapeutic potential of curcumin against iron overload.

The effects of curcumin on hepatic T2*MRI and liver enzymes in patients with β‐thalassemia major: a double‐blind randomized controlled clinical trial

“…Alizadeh et al conducted an animal study and divided 50 Wistar rats into three groups. Similar to the findings of our study, they found that curcumin significantly reduced the levels of ALT, AST, and antioxidants in the blood ( Özbolat and Yegani, 2021 ). Curcumin also caused a significant decline in liver enzymes and cholesterol levels ( Panahi et al, 2016 ; Rahmani et al, 2016 ).…”
