Objective: The aim of the present study was to investigate whether intradialytic parenteral nutrition can affect the antioxidant capacity of hemodialysis patients aged over 60 years.

Methods: The study comprised 20 participants from the Baskent University Umitkoy Dialysis Center; 10 who had intradialytic parenteral nutrition [IDPN, study group (SG)] that included 500 cc of amino acid solution and 500 cc of dextrose were compared with the group that did not have IDPN for 1 month. The randomly selected group had IDPN. Serum albumin, prealbumin, cholesterol, blood urea nitrogen (BUN), creatinine, potassium, and phosphorus; weight; body mass index (BMI); hand muscle strength (HMS); and middle upper arm circumference (MUAC) were measured and compared at baseline and at the end of the study between two groups. After 4 weeks of treatment, thiobarbituric acid reactive substances (TBARS), glutathione peroxidase (GSH-Px), total antioxidant capacity (TAC), and tumor necrosis factor-alpha (TNF-α) values of two groups were compared.

Results: There was no statistically significant difference between the baseline and outcome values of both groups in weight, BMI, HMS, MUAC, BUN, creatinine, potassium, albumin, and cholesterol values during the 1 month period. The SG had 19.97±7.18 kcal/kg/day energy and 0.77±0.21 g/kg/day protein intake. The control group (CG) had 18.66±3.22 kcal/kg/day energy and 0.64±0.11 g/kg/day protein intake. TBARS were 1.84±0.10 μM in the SG and 1.95±0.11 μM in the CG (p=0.031). The mean of TAC was 334.34±23.20 mmol/L in the SG and 290.23±17.72 mmol/L in the CG (p=0.002). The mean of GSH-Px was 305.63±35.31 U/L in the SG and 244.80±17.66 U/L in the CG (p=0.001). The mean of TNF-α was 171.24±25.37 pg/mL in the SG and 193.85±11.82 in the CG (p=0.017).

Conclusion: Results suggest that energy and protein intake were very low in both groups. TBARS and TNF-α were lower in the SG than in the CG. TAC and GSH-Px were higher in the SG than in the CG. IDPN can be used both to increase the protein and energy intake and antioxidant capacity for patients aged over 60 years.
