Insights
A new model accurately predicts growth hormone (GH) treatment response in prepubertal Japanese children. This tool uses early growth markers to forecast long-term height velocity, aiding personalized treatment decisions.
Area of Science:
- Pediatric Endocrinology
- Growth Hormone Therapy
- Biostatistics
Background:
- Individual responses to growth hormone (GH) treatment vary significantly.
- Assessing treatment efficacy requires individualized patient evaluation.
Purpose of the Study:
- To develop a predictive model for growth response to GH treatment.
- Focus on prepubertal Japanese children with GH deficiency.
Main Methods:
- Enrolled pediatric patients with GH deficiency.
- Measured auxological data, GH status, and bone metabolism markers.
- Utilized multiple regression analysis to evaluate prediction models based on early treatment data.
Main Results:
- A predictive model combining height velocity (HV) at 3 months, IGFBP-3, SDS, and pyridinoline at 3 months showed the best prediction.
- This model accurately forecasted HV at 36 months of GH treatment.
Conclusions:
- The developed model accurately predicts the first three years of growth response in prepubertal Japanese children undergoing GH replacement therapy.
- Early prediction is possible after just three months of treatment.
Background:
Individual responses to growth hormone (GH) treatment are variable, and efficacy should be judged in each individual patient.
Objective:
The aim of this study was to develop a prediction model for the growth response of GH treatment in Japanese prepubertal children with GH deficiency.
Patients And Methods:
Pediatric patients with GH deficiency were enrolled. Auxological measurements, markers of GH status, and markers of bone metabolism were measured at baseline and at 3 and 6 months after the start of GH treatment. Correlations with height velocity (HV) at 36 months of GH treatment were calculated. Prediction models were evaluated by multiple regression analysis.
Results:
The model, which combined the parameters of HV at 3 months, insulin-like growth factor-binding protein 3, standard deviation score, and pyridinoline at 3 months, best predicted HV at 36 months.
Conclusions:
This model can accurately predict the first 3 years of growth response after 3 months of GH replacement therapy in prepubertal Japanese children.
