Thalassemia major (TM) results in hemolytic anemia, an increase in intestinal iron absorption, and occurrence of iron loading due to erythrocyte transfusion; the disease is characterized by oxidative damage in major organs. Oxidative stress leads to vascular endothelial damage and forms the basis for serious cardiovascular diseases. Pentraxin-3 (PTX-3) is one of the markers of vascular endothelial damage that increases in response to the oxidative stress, which can be used as an early diagnostic marker for inflammation. This study's purpose is to define the relation between PTX-3 and the vascular endothelial damage that increases with oxidative stress in thalassemia patients. Our study included 35 TM patients, 30 β-thalassemia minor patients, and 30 healthy children. As a result of our study, in TM patients, a positive relation was detected between the PTX-3 levels and the total oxidative stress, triglyceride, and very low-density lipoprotein values, whereas a negative relation was detected with the total antioxidant capacity and high-density lipoprotein values. This result shows that as oxidant stress increases, PTX-3 levels also increase; very low-density lipoprotein and triglyceride contribute to the endothelial damage occurring with oxidative stress. As a result, it was concluded that vascular endothelial damage in thalassemia patients can be evaluated through the serum PTX-3 level.
重型地中海贫血(TM)会导致溶血性贫血、肠道铁吸收增加以及因红细胞输血而出现铁负荷;该疾病的特征是主要器官发生氧化损伤。氧化应激会导致血管内皮损伤,并构成严重心血管疾病的基础。五聚素-3(PTX-3)是血管内皮损伤的标志物之一,其会因氧化应激而升高,可作为炎症的早期诊断标志物。本研究的目的是确定PTX-3与地中海贫血患者中因氧化应激而增加的血管内皮损伤之间的关系。我们的研究纳入了35例TM患者、30例轻型β地中海贫血患者和30名健康儿童。我们的研究结果显示,在TM患者中,PTX-3水平与总氧化应激、甘油三酯和极低密度脂蛋白值之间存在正相关,而与总抗氧化能力和高密度脂蛋白值之间存在负相关。这一结果表明,随着氧化应激的增加,PTX-3水平也会升高;极低密度脂蛋白和甘油三酯会导致氧化应激引起的内皮损伤。因此,得出结论,地中海贫血患者的血管内皮损伤可通过血清PTX-3水平进行评估。
