Effect of Oral Nutritional Supplementation Combined With Impedance Vectors

Summary

The objective of this study was to assess the effect of oral nutritional supplementation (ONS) combined with bioelectrical vector analysis (BIVA) on the nutritional and hydration status and the quality of life (QoL) in hemodialysis (HD) patients. Design and Methods: Thirty-two chronic HD patients were included in a 6-month randomized pilot study. Patients in SUPL group received a simultaneous intervention consisting of a personalized diet, 245 mL/d ONS and dry weight adjustment through BIVA. Patients in CON group received a personalized diet and dry weight adjustment by BIVA. Anthropometrical, biochemical, dietary, QoL, handgrip strength (HGS) and bioimpedance measurements were performed. Malnutrition Inflammation Score (MIS) was applied.

Conditions

• Chronic Kidney Disease Requiring Chronic Dialysis
• Overhydration
• Undernutrition

Interventions

DIETARY_SUPPLEMENT

Proteinex and Enterex DBT Victus Laboratories

The supplement was provided five days per week. Three days a week, the supplement was given at the beginning of the HD session and the patients were instructed to consume it slowly during the next 3 hours. The remaining two days, the supplement was consumed at home and instructed to be consumed between meals. The ONS consisted of one can of polymeric formula (Enterex DBT, Victus Laboratories) and 5.6 g of a protein powder supplement (Proteinex, Victus Laboratories). The final mixture provided 240 kcal, 17 g protein, 8.1 g lipids, 25 g carbohydrates, 4 g dietary fiber, 201 mg sodium, 490 mg calcium, 356 mg phosphorus and 371 mg potassium

PROCEDURE

Dry weight adjustment through BIVA

Those participants with post-dialysis vectors located within the 50 or 75% ellipses, were considered to be in dry weight, so they did not require any fluid removal adjustment. However, participants with vectors outside the 75% ellipse were considered overhydrated or dehydrated and dry weight was adjusted. In these patients, if the vectors fell outside the 75% ellipse but within the 95%, above or below the major axis, the established dry weight was adjusted by 0.5 Kg. If the vectors fell outside the 95% ellipse, the weight was adjusted by 1.0 Kg.
