Background
Protein energy wasting and overhydration are two complications present in renal patients that must be treated simultaneously. The objective of this study was to compare the effectiveness of the simultaneous use of BIVA and oral nutritional supplementation against the exclusive use of BIVA on the nutritional status and body composition of patients on hemodialysis
Methods
Patients were randomized in two groups for 6 months intervention. In both groups, dry weight was adjusted by BIVA as necessary to reach euhydration. Group A (n=17) an individualized diet plus one can of nutritional supplement was given daily to patients. Group B (n=15) only the specific diet was provided. Nutritional status was evaluated with the Malnutrition Inflammation Score (MIS) and handgrip strength was measured at the beginning and the end of the study
Results
Mean age was 55.76 ± 17.6 years for group A and 53.71 + 11.8 for group B, dialysis vintage 24.47 ± 5.08 months and 18.88 ± 11.04 respectively. No significant baseline differences between groups were found and any patient was well nourished. After intervention, nutritional status improved significantly in group A, from 47 to 83% for mild undernutrition and from 53 to 17% for moderate undernutrition (p<0.05), while in group B, nutritional status worsened from 53 to 27% for mild undernutrition and from 47 to 73% for moderate undernutrition (p<0.05). Handgrip strength was increased in 58% of patients in group A and 21% in group B (p < 0.03). Dry weight was achieved in 100% of patients in both groups. At the end of the study, group A vectors indicated less body fluid and better nutritional status, unlike to the vectors of group B which indicated less body fluid but a worse nutritional status. (p<0.007 A vs. B)
Conclusion
Conjunctive use of oral nutritional supplementation and bioelectrical impedance vectors analysis, to determine dry weight, improves nutritional status and body composition in patients undergoing hemodialysis
