Nutritional Status In A Cohort Of Hemodialysis Patients Receiving Tocotrienol Supplementation, Rajeev Shahani

Kidney disease is defined by a loss of kidney function over time [1]. It is expressed in terms of glomerular filtration rate at five stages calculated by the MDRD formula [5]. The fifth stage (<15 mL/min/1.73m2) is designed as end stage renal disease requiring renal replacement therapy in the form of hemodialysis [5]. This requires the use of an artificial kidney (dialyzer) to filter out by-products from the blood for excretion [8]. The issue arises when toxin accumulation due to decreased renal function, dialytic factors such as incompatible dialyzer membranes reacting with blood, and co-morbid conditions such as infection or diabetes mellitus [3]. This increases inflammation within the body, leading to a negative nutrient/energy balance, resulting in a loss of body mass thereby increasing the mortality risk [10]. Tocotrienols (T3), a more potent and underutilized form of Vitamin E, are being administered to attenuate this increase in inflammation via supplementation in addition to food intake. In order to attend to this issue, the nutritional status was assessed utilizing three measures: examining nutrient intake profiles (while supplementation was taken into consideration), obtaining anthropometric findings of body mass index, and analyzing biochemical profiles of serum albumin and pro-inflammatory markers (i.e. IL-6). This data was obtained via a randomized, double blind, placebo-controlled study of 81 dialysis patients. At two times over the course of 16 weeks, blood collection for serum albumin and inflammatory markers was analyzed and dietary intake was assessed using 24-hour diet recalls and Nutritionist Pro software. Statistical analyses of paired t-tests and correlation studies revealed no significant differences between the two groups later showing no noticeable effect of T3 supplementation. Reasoning may be multifactorial such as underestimation of food intake, transcription of diet recalls may not be truly representative, or T3 supplements may not have had an effect on the nutritional statuses. It may be beneficial for patients to receive more extensive nutritional counseling as opposed to nutritional supplementation to ensure compliancy with recommended intakes.

Chronic hemodialysis (HD) patients have an increased risk of cardio vascular diseases (CVD) driven by dyslipidemia, oxidative stress and inflammation. Vitamin E isomers (tochopherols and tocotrienols) are fat-soluble anti oxidants. Tocotrienol isomers (T3) are fewer studies than tochopherol isomers, but they have multifaceted effects on oxidative stress, inflammation and lipid metabolism. We investigated the lipid modifying effects of tocotrienol rich fractions (TRF) on CKD patients receiving HD in a randomized, placebo-controlled, double-blind parallel trial on 81 patients (43M, 38F). Subjects (n=41) were given 220 mg/day of either TRF (180mg TRF, comprising of 34% áT3, 3%âT3, 50% ãT3, 13%äT3 and 40 …
