Cardiology in the Young, 1-6.1047-95111467-1107http://dx.doi.org/10.1017/S1047951122004206https://hdl.handle.net/20.500.12713/3963Aim:Beta-thalassemia major requires regular blood transfusions throughout life, which in turn leads to iron accumulation in the body. While cardiac T2* MRI is the gold standard in determining cardiac iron accumulation, it is not always feasible, which has led to the search for new biomarkers. Herein, the value of growth differentiation factor-15, galectin-3, and N-terminal pro-B-type natriuretic peptide in predicting cardiac iron accumulation is investigated in asymptomatic children with beta-thalassemia major. Materials and method:Forty-one patients aged 11-21 years and 41 age-, gender-, body mass index-matched healthy controls were included. Serum growth differentiation factor-15, galectin-3, and N-terminal pro-B-type natriuretic peptide levels were compared between the patients and controls. Additionally, the relations of these biomarkers with cardiac and liver T2 * MRI were investigated in the patients. Results:In the patients, growth differentiation factor-15, galectin-3, and N-terminal pro-B-type natriuretic peptide levels were higher than healthy controls (p < 0.001, p = 0.025, p < 0.001, respectively). There were no significant correlations of growth differentiation factor-15 and N-terminal pro-B-type natriuretic peptide levels with both cardiac and liver T2 * MRI measurements. While there was no significant correlation of serum galectin-3 with cardiac T2 * MRI measurements, a negative correlation was found with liver T2 * MRI measurements (p = 0.040, rho = -0.325). Conclusion:All three biomarkers investigated in this study failed to predict myocardial iron accumulation in asymptomatic children with beta-thalassemia major. However, a weak relation between serum galectin-3 level and hepatic iron accumulation was demonstrated.eninfo:eu-repo/semantics/openAccessGalectin-3Growth Differentiation Factor-15Iron AccumulationN-Terminal Pro-B-Type Natriuretic PeptideT2*MRIThalassemia MajorArticle36606531WOS:0009083012000012-s2.0-85176969563Q410.1017/S1047951122004206
