Thalassemia major is the most severe form of thalassemia and occurs with the impaired synthesis of β-globin which causes the accumulation of unpaired alpha globin chain. Patients with beta thalassemia major can only survive with periodically safe blood transfusions leading to the accumulation of iron in the bloods of patients, and this causes several endocrinopathies. Although iron overload in thalassemic patients has been extensively studied, there is little information about the levels of other trace elements. The aim of this study was to investigate the differences of serum concentrations of sodium, magnesium, calcium, manganese, iron, copper, and zinc for patients with major β-thalassemia. Concentration of elements was determined by inductively coupled plasma-mass spectrometry system. The statistical difference between the elemental concentrations of the patient and control groups was found by the Mann-Whitney U test. In addition, the relationship between concentrations of the measured elements for each group was determined by the Spearman correlation test. The results revealed that iron, zinc, magnesium, and manganese serum levels of thalassemic patients were significantly higher than the control group while calcium concentration was statistically lower than the control group. There was no significant difference observed for copper and sodium levels of patients when compared to the healthy control group.
重型地中海贫血是最严重的地中海贫血形式,由于β-球蛋白的合成受损,导致未配对的α-球蛋白链积累。重型β-地中海贫血患者只能通过定期安全输血存活,这导致患者血液中的铁积累,从而引起多种内分泌疾病。尽管地中海贫血患者的铁过载已经得到广泛研究,但关于其他微量元素水平的信息却很少。本研究旨在探讨重型β-地中海贫血患者血清中钠、镁、钙、锰、铁、铜和锌浓度的差异。通过电感耦合等离子体质谱系统测定元素浓度。采用曼-惠特尼 U 检验比较患者组和对照组元素浓度的统计学差异。此外,通过 Spearman 相关检验确定每组测量元素之间的浓度关系。结果表明,地中海贫血患者的铁、锌、镁和锰血清水平明显高于对照组,而钙浓度明显低于对照组。与健康对照组相比,患者的铜和钠水平无显著差异。
