This study was undertaken to determine the association of inflammatory biomarker, oxidative stress and antioxidant capacity marker with fetal haemoglobin (HbF) level among sickle cell trait and sickle cell disease (SCD) patients in Chattisgarh. The study group consisted of 51 SCD (SS) patients with painful episode, 49 SCD (SS) patients with steady state, 50 sickle cell trait (AS) and 50 controls. Malondialdehyde (MDA), CRP, total antioxidant power (FARP), total thiol and HbF levels were quantified. We found a significant positive (p < 0.0001) association between CRP and MDA levels and its inverse association with HbF level in SS patients. We also observed that antioxidant capacity had significantly positively (p < 0.0001) associated with HbF level. The protective effect of HbF was found, because the increase in HbF levels resulted in decrease in lipid peroxidation and inflammation in SCD patients. A decrease in the HbF level and its antioxidant capacity has been associated with the pathogenesis of SCD. These finding may explain the high level of HbF is ameliorating oxidative stress and inflammation in SCD patients.
本研究旨在确定恰蒂斯加尔邦镰状细胞性状和镰状细胞病(SCD)患者中炎症生物标志物、氧化应激和抗氧化能力标志物与胎儿血红蛋白(HbF)水平之间的关联。研究组包括51例有疼痛发作的SCD(SS)患者、49例病情稳定的SCD(SS)患者、50例镰状细胞性状(AS)患者和50例对照。对丙二醛(MDA)、CRP、总抗氧化能力(FARP)、总硫醇和HbF水平进行了定量分析。我们发现,SS患者中CRP与MDA水平之间存在显著正相关(p < 0.0001),且与HbF水平呈负相关。我们还观察到,抗氧化能力与HbF水平呈显著正相关(p < 0.0001)。发现了HbF的保护作用,因为HbF水平的升高导致SCD患者脂质过氧化和炎症反应降低。HbF水平及其抗氧化能力的降低与SCD的发病机制有关。这些发现可能解释了高水平的HbF可改善SCD患者的氧化应激和炎症反应。
