BACKGROUND: There is evidence that iron affects lipid metabolism and adipocyte biology. Given the effects of iron on adiponectin, the role of iron in lipid oxidation, and the potential additive effects of oxidative stress from excess iron and lipid metabolism. We aimed to investigate serum adiponectin in relation to clinical and laboratory parameters including the inflammation markers [C-reacitve protein (CRP) and interleukin-6 (IL-6)] in β-thalassaemia major children. METHODS: We investigated 58 β-thalassaemia major children under scheduled blood transfusion and 30 controls. Routine clinical evaluation, laboratory investigations including serum ferritin as well as CRP measured by immunoturbidimetry, IL-6 and serum adiponectin measured by ELISA are performed. RESULTS: CRP, IL-6 and serum adiponectin levels were higher in patients than controls (p<0.001, p=0.04 and p<0.001, respectively). Patients received desferoxamine showed significantly lower levels of adiponectin than those did not receive it (mean±SD=4.50±3.37 vs. 9.96±9.68, p=0.006). Serum adiponectin was significantly negatively correlated with hemoglobin (Hb) concentration (r=-0.36, p=0.005). It was significantly positively correlated with platelets count, serum ferritin, CRP and IL-6 (r=0.27, r=0.26, r=0.30, r=0.35, respectively and p=0.04, p=0.04, p=0.01, p=0.008, respectively). Serum ferritin and IL-6 were the significant predictors of serum adiponectin level (p<0.001 and p=0.003, respectively). CONCLUSIONS: Serum adiponectin was increased in β-thalassaemia major as were pro-inflammatory markers (CRP and IL-6). Its level is directly associated with ferritin and IL-6 levels.
