Remarkable catch-up growth in a boy with steroid-responsive nephrotic syndrome
Insights
High-dose corticosteroid treatment for nephrotic syndrome can significantly impact growth. Discontinuous therapy, however, allowed for catch-up growth in a pediatric patient, improving final height outcomes.
Area of Science:
- Pediatric Endocrinology
- Nephrology
- Growth and Development
Background:
- Steroid-responsive nephrotic syndrome requires long-term treatment, often with corticosteroids.
- Corticosteroids are known to affect growth and skeletal maturation in children.
Observation:
- A boy with nephrotic syndrome received high-dose corticosteroids from age 4 to 21.5.
- Continuous corticosteroid therapy for 10 years resulted in significant height reduction (from -0.5 to -4.5 SDS).
- Skeletal age was retarded, with a notable discrepancy between short bone and carpal bone development.
Findings:
- Discontinuous corticosteroid treatment, maintaining the total weekly dose, led to rapid catch-up growth.
- The patient achieved a final height of -1.0 SDS.
Implications:
- Treatment protocols for pediatric nephrotic syndrome may need adjustment to mitigate growth suppression.
- Intermittent corticosteroid administration could be a strategy to improve final height in children with chronic conditions.
- Further research is needed to understand the long-term effects of different corticosteroid dosing schedules on skeletal development.
Abstract:
A boy is described who was followed from 4 to 21.5 years of age, during which time he was treated with high doses of corticosteroids for a steroid-responsive nephrotic syndrome. For the first 10 years therapy was mainly continuous and height decreased from -0.5 to -4.5 SDS. Later discontinuous treatment without a reduction in the total weekly dose was accompanied by rapid catch-up growth. Final height was -1.0 SDS. During most of the time skeletal age was severely retarded and a discrepancy between the development of the short bones of the hand and the carpal bones was noted.
