Abstract:

affecting serum Potassium (K) levels in Hemodialysis (HD) patients. We aim to analyze the effect of Fuji Apple Juice (AJ) intake on Oxidative Stress (OS) and biochemical parameters after a single HD session in chronic HD patients. Case Report: Six HD patients consumed 300 mL and 150 mL of Fuji AJ (Malus domestica Borkh) on different days, immediately after a single HD session. A 3-week washout period was applied between the two doses. Blood samples were collected before and after 30 min and 60 min. We analyzed the total antioxidant status, Total Oxidant Status (TOS), Ascorbic Acid (AA), catalase, glutathione peroxidase, Superoxide Dismutase (SOD), and reduced glutathione, as well as biochemical parameters including phosphorus, K, Uric Acid (UA), and glucose. After both trials, patients were questioned by telephone about AJ tolerance. Conclusion: The 300 mL of AJ significantly increased TOS (p=0.05), AA (p=0.001), UA, and K levels (p ≤ 0.00) over time, while SOD activity increased significantly only after 30 min (p=0.02). After 150 mL of AJ, UA and phosphorus levels increased significantly (p<0.00). Acute AJ intake did not affect bowel habits and no adverse gastrointestinal events were reported. Thus, acute AJ intake was well tolerated and 300 mL of AJ may provide mild-favorable effects on antioxidant status without exceeding recommended values of serum K in HD patients.
