Abstract:
The effects of keto acid (KA) supplements on Chinese patients receiving maintenance hemodialysis (MHD) are unclear. This study aimed to evaluate the effects of KA supplementation on nutritional status, inflammatory markers, and bioelectric impedance analysis (BIA) parameters in a cohort of Chinese patients with MHD without malnutrition. Methods: This was a prospective, randomized, controlled, single-center clinical study conducted in 2011 till 2014. Twenty-nine patients with MHD were randomly assigned to a control ( n = 14) or a KA ( n = 15) group. The control group maintained a dietary protein intake of 0.9 g/kg/day. The KA group received additional KA supplement (0.1 g/kg/day). BIA was used to determine the lean tissue mass, adipose tissue mass, and body cell mass. The patients’ nutritional status, dialysis adequacy, and biochemical parameters were assessed at the ends of the third and sixth months with t test or Wilcoxon rank-sum test. Results: The daily total energy intake for both groups was about 28 kcal/kg/day. After 6 months, the Kt / V (where K is the dialyzer clearance of urea, t is the dialysis time, and V is the volume of the distribution of urea) was 1.33 ± 0.25 in KA group, and 1.34 ± 0.25 in the control group. The median triceps skin-fold thickness in KA group was 12.00 and 9.00 mm in the control group. In addition, the median hand-grip strength in KA group was 21.10 and 25.65 kg in the control group. There were no significant differences between the groups with respect to the anthropometry parameters, dialysis adequacy, serum calcium and phosphorus levels, inflammatory markers, and amino-acid profiles, or in relation to the parameters determined by BIA. Both groups achieved dialysis adequacy and maintained nutritional status during the study. Conclusions: In this cohort of Chinese patients with MHD, the patients in the control group whose dietary protein intake was 0.9 g/kg/day and total energy intake was 28 kcal/kg/day, maintained well nutritional status during study period. The KA supplement (0.1 g/kg/day) did not improve the essential amino acid/non-essential amino acid ratio, nor did it change the patients’ mineral metabolism, inflammatory parameters, or body compositions.
