Insights
A protein-restricted diet did not improve kidney function or growth in children with chronic renal failure. This three-year study found no significant benefits for children with kidney disease adhering to a specialized diet.
Area of Science:
- Pediatric Nephrology
- Nutritional Science
Background:
- Chronic renal failure (CRF) in children presents significant challenges to growth and renal function.
- Dietary interventions, particularly protein restriction, are often considered for managing pediatric CRF.
Purpose of the Study:
- To evaluate the impact of a protein-restricted diet on renal function and growth in pediatric patients with chronic renal failure.
Main Methods:
- A multicenter, prospective study involving 56 children (aged 2-18 years) with CRF.
- Random assignment to either a protein-restricted diet (0.8-1.1 g/kg/day) or a control group.
- Three-year follow-up with consistent pediatric and dietitian care, monitoring glomerular filtration rate and growth parameters.
Main Results:
- No significant differences were observed in glomerular filtration rate between the protein-restricted and control groups.
- Weight-for-height and height standard deviation scores showed no significant improvement in the protein-restricted group.
- Good compliance with the protein-restricted diet was confirmed through diet diaries and serum urea:creatinine ratios.
Conclusions:
- A protein-restricted diet does not confer significant benefits on renal function or growth in children with chronic renal failure.
- Current dietary recommendations for pediatric CRF may need re-evaluation regarding protein intake.
Abstract:
The aim of the study was to investigate the effect of a protein restricted diet on renal function and growth of children with chronic renal failure. In a multicentre prospective study 56 children (aged 2-18 years) with chronic renal failure were randomly assigned to the protein restricted (0.8-1.1 g/kg/day) or the control group. All children were followed up by the same paediatrician and dietitian. After a follow up period of three years there was no significant difference in glomerular filtration rate between children on a protein restricted diet and children of the control group. There was no significant difference in weight with respect to height and height SD score between the protein restricted and the control group. Compliance with the protein restricted diet, as indicated by the prospective diet diaries and the serum urea:creatinine ratio, was good. This study shows that children with chronic renal failure do not benefit from a protein restricted diet.
