Principles of nutrition in chronic kidney disease in children - a review of the clinical trials and recommendations

Abstract

Introduction: Children with chronic kidney disease (CKD) require a specialized diet to manage their condition and support healthy growth and development. A proper diet for children with CKD aims to control the intake of certain nutrients, such as protein, lipid, calcium, phosphorus, potassium, sodium, and vitamin D, while ensuring they receive adequate nutrition for growth and development. Aim of the study: This article discusses the epidemiology, causes and pathomechanism of CKD in children. It also presents existing clinical trials and dietary recommendations from societies such as Kidney Disease: Improving Global Outcomes (KDIGO) 2024, Kidney Disease Outcomes Quality Initiative (KDOQI) and Pediatric Renal Nutrition Taskforce (PRNT) and identifies potential sources of selected macronutrients and micronutrients in children's diets. Materials and methods: Comprehensive literature searches were performed across the main electronic databases of PubMed, Google Scholar, KDIGO2024, KDQQI and PRNT recommendations for studies published in the English language about dietary recommendations for children with CKD. Results: The approach to nutrition for children with CKD is still evolving, and specific macronutrient and micronutrient ratios should be established based on the clinical condition, the child's age, and body weight. Care should be taken to ensure that the child's diet is varied, and a healthy eating style should be promoted.
