Summary

This study introduces a new screening method for growth hormone deficiency (GHD) in children using growth rate and insulin-like growth factor I. This approach aims to improve diagnostic accuracy and reduce the need for invasive stimulation tests.

Area of Science:

  • Pediatric Endocrinology
  • Growth Hormone Research
  • Diagnostic Screening

Background:

  • Current criteria for predicting growth hormone deficiency (GHD) rely on auxological parameters and stimulation tests.
  • Existing criteria are highly sensitive but lack specificity, leading to unnecessary tests.
  • The need for improved screening methods to accurately identify GHD is critical.

Purpose of the Study:

  • To develop an improved screening method for GHD in children.
  • To enhance the specificity of GHD screening, thereby reducing the reliance on stimulation tests.
  • To differentiate between GHD, normal GH secretion, and transient GHD.

Main Methods:

  • Patients were categorized into three groups: GHD with pituitary stalk interruption syndrome (n=54), normal GH peak (n=104), and transient GHD (n=19).

  • Growth hormone deficiency diagnosis was based on GH Research Society parameters, including plasma insulin-like growth factor (IGF) I concentrations.
  • Logical analysis of data framework was employed for data analysis.

    • Main Results:

    • A screening graph utilizing IGF I and growth rate (GR) effectively categorized patients.
    • Patients below the line (GR < or =-7.3 - 1.3xIGF (SDS)) were diagnosed with GHD.
    • Patients above the line (GR >-4.5 + 6.4/(IGF + 4.5) (SDS)) were generally not diagnosed with GHD; a 'gray area' required further evaluation, often including transient GHD.

    Conclusions:

    • Growth rate and IGF I serve as effective screening tools for GHD in short children.
    • Magnetic resonance imaging is recommended for detecting pituitary stalk interruption syndrome or tumors in specific cases.
    • The proposed screening method enhances diagnostic accuracy and potentially reduces the need for stimulation tests.
