Palm Tocotrienols in Chronic Hemodialysis (Malaysia) (PATCH)
- Conditions
- Chronic Kidney Failure

- Dietary Supplement: PlaceboDietary Supplement: TRF
- Registration Number
- NCT02913690
- Lead Sponsor
- Wayne State University
- Brief Summary
This study aims to determine if tocotrienol rich fraction (TRF) supplementation can improve markers of inflammation, oxidative stress and blood lipids in Malaysian hemodialysis (HD) patients.
- Detailed Description
This study is a multi-centered, randomized, double blind, placebo-controlled trial where a total of 400 HD patients (200 supplemented; 200 control) will be recruited from government and private settings. Subjects will be randomized to either the intervention or control group. The intervention group will receive TRF (300 mg), daily for 12 months while the control group will only receive placebo, daily for 12 months. In addition, both groups will receive standard dietary counseling to ensure compliance to medical nutrition therapy guidelines for dialysis patients.
Patients who consented will be first subjected to a screening for identification of eligible subjects. The screening will involve basic anthropometry measures (height, weight, BMI), routine biochemistry result obtained from medical record, assessment of nutritional status and dietary evaluation. About 15ml of pre-dialysis blood will be collected by respective nurses for additional laboratory parameters (hsCRP, atherogenic profile and other inflammatory markers).
Patients who fulfill the inclusion criteria will be randomized to either control or intervention group. During the 12 months of treatment period, patients in both control and intervention groups will be assessed at baseline and 3-monthly intervals for laboratory results, medical condition, hospitalizations, nutritional status, dietary intake and compliance towards supplementation (intervention group only). A final measurement will be taken 3 months after study completion as a post follow up assessment upon cessation of supplementation. In all, patient data will be generated at 6 time points.
(A similar study, following a similar protocol and using the same study design and intervention will recruit 400 patients total (200 for each group) in Michigan, USA).

- Arm && Interventions
Group Intervention Description Control group Placebo Control group will be supplemented with placebo for 12 months. Intervention group TRF The intervention arm will be supplemented with TRF for 12 months.
- Primary Outcome Measures
Name Time Method Improvement in inflammatory marker based on the mean change from baseline to 12 months. Baseline to 12 months Changes in biochemistry marker namely hsCRP (mg/dL)
- Secondary Outcome Measures
Name Time Method Changes in anthropometry measures Baseline to 12 months This includes body mass index (kg/m2) and skin fold measurements such as mid arm circumference (cm), mid-arm muscle circumference (cm), mid-arm muscle area (cm2) and triceps skin fold (mm)
Changes in restless leg syndrome scoring Baseline to 12 months Based on restless leg syndrome questionnaire
Changes in muscle strength Baseline to 12 months Handgrip strength (in kilogram) will be measured using hand held dynamometer
Changes in qualify of life (QOL) Baseline to 12 months Subjects will be interviewed using SF-36 \& KD-QOL questionnaire which will derive QOL score.
Changes in rate of hospitalisation Baseline to 12 months Difference in frequency of hospitalisation between the groups during the 12 months will be determined.
Changes in metabolomics analyses Baseline to 12 months Metabolomic analyses (using blood specimens) will be carried out to determine differences in metabolites between the groups.
Changes in plasma lipids Baseline to 12 months Based on biochemistry results for TC, LDL-C, HDL-C, triglyceride (TG), atherogenic profile, cholesteryl ester transfer protein (CETP), lecithin cholesterol acyltransferase (LCAT), apolipoprotein A1(ApoA1), apolipoprotein B-100 (ApoB-100)
Changes in body composition Baseline to 12 months Body composition assessment pertaining to hydration status, lean tissue mass and fat mass is derived using a portable BIA device.
Changes in dietary intake Baseline to 12 months Dietary intake will be assessed using a 3-day 24-hr diet recalls to determine macro and micronutrient intake.
Changes in nutritional status Baseline to 12 months Patients will be screened with the Malnutrition Inflammation Score questionnaire to categorize their nutritional status.
Changes in biochemistry parameters Baseline to 12 months Routine blood parameters (renal, liver function,lipid, hematology profile and dialysis adequacy) will be obtained from patients' medical records. Additional fasted blood sampling will be obtained to determine lipid biomarkers (CETP, LCAT, ApoA1, ApoB-100, lipoprotein particles) as well as inflammation and oxidative stress markers (hs-CRP, IL-6, F-isoprostane).
