Sickle cell disease is characterized by clinical complications resulting in vaso-occlusive crisis with prominent attributes of oxidative stress, inflammation, and pain. Inflammation is an integral part of this disease which further exacerbates the pain during a crisis. Omega-3 fatty acids are known to possess anti-inflammatory and anti-aggregatory properties and assist in diminishing the slow physiological inactivation.
A pilot nutritional interventional study was conducted wherein forty-three children with sickle cell disease aged 5-16 years were supplemented with omega-3 fatty acids for a period of six months. Analysis of oxidative stress, as well as inflammatory parameters, was done pre and post-supplementation.
Increased free oxygen radical transference values depicting free radical generation is enhanced in these patients along with a reduced antioxidant defense, as seen by decreased free oxygen radical defense values. Supplementation with omega-3 fatty acids for a period of six months significantly reduced the inflammatory marker homocysteine in all patients, whereas high sensitive C reactive protein was significantly reduced only in females of the age group 11-16years. Simultaneously a significant reduction in oxidative stress parameters with a concomitant increase of antioxidant defense was observed in all patients.
The authors' findings suggest the regulatory effects of omega-3 fatty acids as cellular activators in alleviating the complications due to sickle cell disease. Omega-3 fatty acids hold promise as future therapeutic candidates in patients with sickle cell disease.
镰状细胞病的特征是临床并发症,导致血管闭塞性危机,并伴有氧化应激、炎症和疼痛等突出特征。炎症是这种疾病不可或缺的一部分,在危机期间会进一步加剧疼痛。已知ω-3脂肪酸具有抗炎和抗聚集特性,并有助于减少缓慢的生理失活。
进行了一项初步营养干预研究,对43名5至16岁的镰状细胞病患儿补充ω-3脂肪酸,为期6个月。在补充前后对氧化应激以及炎症参数进行了分析。
这些患者中描绘自由基生成的游离氧自由基转移值增加,同时抗氧化防御能力降低,表现为游离氧自由基防御值下降。补充ω-3脂肪酸6个月显著降低了所有患者的炎症标志物同型半胱氨酸,而高敏C反应蛋白仅在11至16岁年龄组的女性中显著降低。同时,在所有患者中观察到氧化应激参数显著降低,同时抗氧化防御能力增加。
作者的研究结果表明,ω-3脂肪酸作为细胞激活剂在减轻镰状细胞病引起的并发症方面具有调节作用。ω-3脂肪酸有望成为镰状细胞病患者未来的治疗候选药物。
