ABSTRACT
ABSTRACT Introduction:
Patients with β-thalassemia major (β-TM) are at risk of developing abnormal lipid profiles. Lipid abnormalities, in turn, have a potential role in the pathogenesis of some clinical aspects of thalassemiaObjectives:
To evaluate lipid levels and atherogenic indices in β-TM patients compared to healthy children and for any association between lipid levels, lipid peroxidation and inflammatory biomarkersMethods:
This case-control study was carried out on 79 patients with β-TM, aged 6 to 16 years, registered at the Basrah Center for Hereditary Blood Diseases and 85 age- and sex-matched apparently healthy children and adolescents. Complete blood count, serum lipids and ferritin, liver function tests, C-reactive protein (CRP), high-sensitivity CRP (hs-CRP) and serum malondialdehyde (MDA) were evaluatedResults:
Patients with β-TM had significantly lower hemoglobin (Hb), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and non-high-density lipoprotein (non-HDL) and significantly higher very low-density lipoprotein (VLDL), triglycerides (TGs), LDL/HDL ratio, MDA, hs-CRP, total serum bilirubin (TSB), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) than the control group (p < 0.05). A bivariate analysis revealed that TC has a significant positive association with Hb. The TG has a significant negative association with Hb and a positive association with serum ferritin. Furthermore, MDA, TG, TSB, ALT and AST were significantly positively correlated with serum ferritin (p < 0.05)Conclusions:
Atherogenic dyslipidemia, defined as a high low-density lipoprotein cholesterol (LDL-C/high-density lipoprotein cholesterol (HDL-C) ratio and high TG level, is common among pediatric β-TM patients, it is associated with iron overload and places patients at an increased cardiovascular risk.Palavras-chave
