Insights
Identifying risk factors for chronic kidney disease (CKD) progression in children is crucial. Recent studies highlight lower kidney function, proteinuria, hypertension, and genetic factors as key indicators for disease advancement.
Area of Science:
- Pediatric Nephrology
- Genetics
- Epidemiology
Background:
- Chronic kidney disease (CKD) progression in children presents unique challenges.
- Understanding risk factors is vital for early intervention and management.
- Recent advancements have refined the study of pediatric kidney failure.
Purpose of the Study:
- To review identified risk factors for chronic kidney disease (CKD) progression.
- To emphasize the specific context of the pediatric population.
- To highlight recent changes in understanding and studying pediatric CKD.
Main Methods:
- Review of recent literature and cohort studies in pediatric CKD.
- Analysis of advancements in glomerular filtration rate (GFR) measurement and estimation equations.
- Inclusion of findings from genome-wide association studies (GWAS).
Main Results:
- Lower kidney function, elevated proteinuria, and hypertension are established markers for rapid GFR decline in pediatric CKD.
- Anemia and other traditional risk factors require further validation.
- GWAS have identified novel genetic loci associated with CKD progression.
Conclusions:
- Mature pediatric CKD cohort studies are refining the assessment of disease progression.
- Traditional risk factors remain important for evaluation.
- Future research will focus on novel genetic risk factors identified through GWAS.
Purpose Of Review:
The present review provides an overview of the identified risk factors for chronic kidney disease (CKD) progression emphasizing the pediatric population.
Recent Findings:
Over the past 10 years, there have been significant changes to our understanding and study of preterminal kidney failure. Recent refinements in the measurement of glomerular filtration rate and glomerular filtration rate estimating equations are important tools for identification and association of risk factors for CKD progression in children. In pediatric CKD, lower level of kidney function at presentation, higher levels of proteinuria, and hypertension are known markers for a more rapid decline in glomerular filtration rate. Anemia and other reported risk factors from the pregenomic era require further study and validation. Genome-wide association studies have identified genetic loci that have provided novel genetic risk factors for CKD progression.
Summary:
With cohort studies of children with CKD becoming mature, they have started to yield important refinements to the assessment of CKD progression. Although many of the traditional risk factors for renal progression will certainly be assessed, such cohorts will be important for evaluating novel risk factors identified by genome-wide studies.
