Abstract

Tocotrienols, isomers of vitamin E, may provide an effective nutritional strategy to mitigate common cardiovascular risks such as dyslipidemia, inflammation, and oxidative stress in patients with chronic kidney disease (CKD). This double-blind, placebo-controlled, randomized clinical trial aimed to evaluate the effects of a tocotrienol-rich fraction (TRF) supplementation (300 mg/day) on oxidative stress and inflammatory markers, including transcription factors in nondialysis (ND) and hemodialysis (HD) CKD patients for three months. Interleukin-6, tumor necrosis factor- (IL-6 and TNF-), C-reactive protein (CRP), lipid peroxidation, biochemical parameters, and transcription factors such as NRF2 and NF-B mRNA expression were evaluated. Seventeen HD patients (9 in the placebo group, 8 in the TRF group) and 16 ND CKD patients (8 in the placebo group and 8 in the TRF group) completed the study. In HD patients, significant reductions were observed in LDL cholesterol (=0.04) and total plasma cholesterol levels (=0.01) after TRF intervention. CRP serum levels decreased significantly in ND CKD patients (=0.05) after TRF supplementation. Transcription factors NRF2 and NF-B mRNA expressions remained unaltered in both groups. This study suggests that TRF supplementation may mitigate dyslipidemia and inflammation, factors involved with increased cardiovascular risk, in CKD patients, with variations in efficacy between HD and ND patients. ClinicalTrials.gov identifier: NCT04900532.

摘要

生育三烯酚是维生素E的异构体,可能为减轻慢性肾脏病(CKD)患者常见的心血管风险(如血脂异常、炎症和氧化应激)提供一种有效的营养策略。这项双盲、安慰剂对照、随机临床试验旨在评估补充富含生育三烯酚的组分(TRF)(300毫克/天)对非透析(ND)和血液透析(HD)CKD患者氧化应激和炎症标志物(包括转录因子)的影响,为期三个月。评估了白细胞介素-6、肿瘤坏死因子-(IL-6和TNF-)、C反应蛋白(CRP)、脂质过氧化、生化参数以及诸如NRF2和NF-κB mRNA表达等转录因子。17名HD患者(安慰剂组9名,TRF组8名)和16名ND CKD患者(安慰剂组8名,TRF组8名)完成了研究。在HD患者中,TRF干预后观察到低密度脂蛋白胆固醇(P = 0.04)和总血浆胆固醇水平(P = 0.01)显著降低。TRF补充后,ND CKD患者的CRP血清水平显著下降(P = 0.05)。两组中转录因子NRF2和NF-κB mRNA表达均未改变。这项研究表明,补充TRF可能减轻CKD患者的血脂异常和炎症,这些因素与心血管风险增加有关,HD和ND患者的疗效存在差异。ClinicalTrials.gov标识符:NCT04900532。
