How do food supplements impact nutritional status and overall health outcomes in children with CKD?8 answersFood supplements have shown varying degrees of impact on the nutritional status and overall health outcomes in children with Chronic Kidney Disease (CKD). Oral protein-based nutritional supplements, for instance, have been associated with a higher mean change in serum albumin and may improve serum prealbumin and mid-arm muscle circumference, indicating a potential positive impact on nutritional status. Similarly, intradialytic oral nutrition in the form of protein bars or meals has been well-tolerated in children and adolescents undergoing hemodialysis, with the majority reporting feeling better post-consumption, albeit with minimal adverse effects. Zinc supplementation, another form of nutritional intervention, has shown benefits for nutritional status in CKD children, particularly with higher doses leading to improvements in body mass and normalization in BMI Z-score. However, the relationship between nutritional status and health outcomes such as health-related quality of life (HRQoL) is complex. For example, HRQoL scores in children with CKD were found to be lower than in healthy controls and were associated with short stature and poor appetite, but not directly with markers of obesity or micronutrient status. Intradialytic parenteral nutrition (IDPN) has been proposed as an effective method for preventing and treating malnutrition in children with CKD, showing significant improvements in height Z-score, lean tissue mass, and serum albumin. Despite these interventions, protein energy wasting remains a challenge in CKD patients, with nutritional supplementation being one of the effective strategies to replenish protein and energy stores. However, excessive intake of certain nutrients, such as vitamin C, may contribute to adverse outcomes like oxalate accumulation. Nutraceuticals, including fatty acids, fiber, and certain plant-derived compounds, have shown potential in exerting beneficial effects on inflammatory pathways and renal disease progression. Comprehensive nutritional assessment is crucial for guiding dietary prescriptions in children with kidney diseases, and specialized nutritional support, including IDPN, has been utilized to address malnutrition in children receiving maintenance hemodialysis. In summary, while food supplements can positively impact the nutritional status of children with CKD, careful consideration of the type, dosage, and potential adverse effects is essential to optimize health outcomes.

What are the specific nutritional requirements for individuals with chronic kidney disease?4 answersIndividuals with chronic kidney disease (CKD) have specific nutritional requirements. Guidelines recommend limiting protein intake as high-protein diets can worsen kidney dysfunction. Excess sodium should be limited as it may be associated with CKD progression and all-cause mortality. Potassium intake should be adjusted on an individual basis to maintain normal serum potassium levels. Adequate dietary calcium intake is recommended to maintain calcium balance. Nutritional therapy, including protein restriction, is beneficial for slowing CKD progression and reducing uremic manifestations, but individualized prescriptions are necessary due to patient adherence and compliance. Protein-energy wasting (PEW) is common in CKD, and dietary counseling by dietitians is key for preventing and managing PEW. Oral nutrition supplements (ONSs) may be necessary if dietary counseling alone is insufficient. In cases where energy and protein requirements are not met, nutrition support such as enteral tube feeding or parenteral nutrition should be considered. Malnutrition is prevalent in CKD patients, and factors such as gender, age, weight loss, and reduced food intake are associated with malnutrition. Disease-related malnutrition in CKD is a complex issue, and further research is needed to understand its pathophysiology and develop effective interventions.
How does the use of specific nutritional supplements impact with actue renal faiulre?5 answersThe use of specific nutritional supplements does not induce renal damage in the studied amounts and durations. Creatine supplements, in particular, are safe and do not cause renal disease, although they should not be used in people with chronic renal disease or using potentially nephrotoxic medications. Nutritional concerns play a major role in the management of patients with end-stage renal disease (ESRD), and protein intake is no longer restricted but rather recommended at 1.0-1.5 g/kg body weight/day. Oral nutrition supplements (ONS) can provide renal patients with key nutrients that may have been lost during dialysis. Antioxidant supplementation with vitamins C or E may improve renal transplant function, especially in grafts donated from marginal donors. Overall, the use of specific nutritional supplements does not appear to have a negative impact on acute renal failure.
