Insights
Children with glomerular diseases experience faster chronic kidney disease (CKD) progression. Early referral to pediatric nephrology centers is crucial for optimal pre-dialysis care in these patients.
Area of Science:
- Pediatric Nephrology
- Renal Medicine
- Chronic Kidney Disease Management
Background:
- Chronic kidney disease (CKD) affects children and adolescents, necessitating specialized management programs.
- Pre-dialysis interdisciplinary programs aim to slow disease progression and improve patient outcomes.
- Understanding the differential progression rates based on etiology is critical for tailored interventions.
Purpose of the Study:
- To describe the outcomes of pediatric patients with CKD in a pre-dialysis interdisciplinary management program.
- To analyze renal survival, patient survival, hypertension, and somatic growth.
- To compare the rate of estimated glomerular filtration rate (GFR) decline across different primary renal disease classifications.
Main Methods:
- Retrospective cohort study of 107 patients with CKD admitted between 1990 and 2006.
- Kaplan-Meier method used for survival analysis.
- Patients categorized into four groups: congenital nephro-uropathies, glomerular diseases, cystic disease, and miscellaneous.
Main Results:
- The overall mean GFR decrease was 5.8 ml/min/1.73 m(2)/year.
- Patients with glomerular diseases exhibited a significantly faster median GFR deterioration rate (10 ml/min/1.73 m(2)/year) compared to other groups (P < 0.001).
- The probability of reaching CKD stage 5 within 5 years was 36%.
Conclusions:
- Glomerular diseases are associated with a more rapid decline in renal function in pediatric CKD patients.
- Early referral to pediatric nephrology centers is recommended for children with glomerular diseases.
- Timely intervention may help avoid suboptimal pre-dialysis care and improve long-term outcomes.
Abstract:
The purpose of this retrospective cohort study was to describe the outcome of 107 patients with chronic kidney disease (CKD) admitted to a pre-dialysis interdisciplinary management program from 1990 to 2006. The events of interest were progression to CKD stage 5 (renal survival), patient survival, hypertension, and somatic growth. Survival was studied by the Kaplan-Meier method. Patients were classified into four groups according to their primary renal disease: congenital nephro-uropathies; glomerular diseases; cystic disease, and miscellaneous. Median follow-up time was 94 months [Interquartile (IQ) range 38-145]. The probability of reaching CKD stage 5 was estimated to be 36% by 5 years after admission. As a whole, the mean estimated glomerular filtration rate (GFR) decrease per year was 5.8 ml/min per 1.73 m(2) body surface area [standard deviation (SD) 12.4]. The glomerular diseases group showed a median rate of GFR deterioration of 10 ml/min per 1.73 m(2) per year (IQ range -24 to -5.7), whereas the median rate of GFR deterioration for the groups with cystic diseases, congenital nephro-uropathies, and miscellanea were 2.5 ml/min (IQ range -10 to +0.34), 2.2 ml/min (IQ range -5.0 to -0.52), and 0.36 ml/min (IQ range -2.5 to +2.6), respectively (P < 0.001). The results of this study support the view that children and adolescents with glomerular diseases present a faster deterioration of renal function. Therefore, patients with glomerular diseases need to be referred early to a pediatric nephrology center so that suboptimal pre-dialysis care might possibly be avoided.
