Neurodevelopmental progress of young children with chronic renal disease
1Department of Paediatrics, Hospital for Sick Children, Toronto, Ontario, Canada.
Insights
Children with chronic renal disease showed developmental delays, with outcomes linked to growth and disease severity. Early diagnosis and treatment are crucial for neurodevelopmental progress in these infants.
Area of Science:
- Pediatrics
- Nephrology
- Developmental Neuroscience
Background:
- Chronic renal disease (CRD) significantly impacts child development.
- Previous studies reported poorer neurodevelopmental outcomes in infants with CRD.
Purpose of the Study:
- To prospectively assess neurodevelopmental progress in infants with chronic renal disease.
- To identify factors influencing neurodevelopmental outcomes in this population.
Main Methods:
- Prospective study of 33 children with CRD over a mean of 1.68 years.
- Evaluation of neurodevelopmental progress, growth, and renal impairment severity.
- Correlation analysis of developmental quotients over time.
Main Results:
- 10 out of 33 children exhibited developmental delays (8 mild, 2 moderate).
- Developmental level correlated significantly with growth and renal impairment severity.
- Strong correlation found between initial and final developmental quotients, suggesting limited improvement.
Conclusions:
- Neurodevelopmental outcomes in infants with CRD may be better than previously reported.
- Early diagnosis and intervention are essential for optimizing neurodevelopmental trajectories.
- Growth and renal disease severity are key predictors of neurodevelopmental outcomes.
Abstract:
Neurodevelopmental progress was prospectively studied in 33 children with chronic renal disease during a mean of 1.68 years. The mean age of the children when first evaluated was 1.11 years. Children with all levels of renal dysfunction were included, although end stage renal disease developed in 17 at some time during the study. When last evaluated, 10 of the children were developmentally delayed, 8 mildly delayed, and 2 moderately delayed. The developmental level achieved was significantly related to the children's growth and to the severity of their renal impairment. Also found was a strong correlation between the developmental quotients at first and final evaluations. This finding suggests that improvement throughout time is unlikely and underlines the need for early diagnosis and treatment of such infants. These observations suggest that the neurodevelopmental outcome of infants with chronic renal disease is considerably better than previously reported.
