  Purpose
We, the investigators at the University of Texas Health Science Center at San Antonio, want to learn if height and IQ (intelligence quotient) scores are improved by growth hormone (GH) treatment in children with chromosome 18 deletions and abnormal growth. Data from a previous study showed that growth hormone improved height in all children with 18q- and growth hormone deficiency. In addition, most of the study participants on growth hormone treatment showed an increase in IQ scores.

Condition Intervention Phase
Loss of Chromosome 18q Growth Hormone Deficiency Drug: Nutropin AQ Procedure: Arginine and Clonidine Stimulation Testing Procedure: Growth Factors Laboratory Testing Procedure: Neuropsychological Testing Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Growth Hormone Trial for Children With 18q- and Abnormal Growth

Secondary Outcome Measures:
  • performance IQ scores 12-15 months after treatment begins

Enrollment: 20
Study Start Date: February 2001
Study Completion Date: June 2005
Primary Completion Date: June 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Growth Hormone Treatment
Arginine and Clonidine Stimulation Testing, Growth Factors Laboratory Testing, and Neuropsychological Testing was done 1st for eligibility and this group received GH (growth hormone) (Nutropin AQ) 0.3 mgs per kg per week (standard dosing for GH)immediately after randomization
Drug: Nutropin AQ
Growth Hormone (Nutropin AQ) treatment given to Group 1 immediately Growth Hormone (Nutropin AQ) treatment given to Group 2 after one year observation
Other Name: Growth Hormone (Nutropin AQ)
Procedure: Arginine and Clonidine Stimulation Testing
This testing was done to determine growth hormone status prior to starting treatment.
Procedure: Growth Factors Laboratory Testing
This involved assessment of growth factors such as IGF#1 before treatment was initiated.
Procedure: Neuropsychological Testing
This testing was done prior to treatment and at the end of treatment.
GH treatment delayed by one year
Arginine and Clonidine Stimulation Testing, Growth Factors Laboratory Testing, and Neuropsychological Testing was done first for eligibility and this group received growth hormone (Nutropin AQ) 0.3 mgs per kg per week (standard dosing for GH)after one year of observation
Procedure: Arginine and Clonidine Stimulation Testing
This testing was done to determine growth hormone status prior to starting treatment.
Procedure: Growth Factors Laboratory Testing
This involved assessment of growth factors such as IGF#1 before treatment was initiated.
Procedure: Neuropsychological Testing
This testing was done prior to treatment and at the end of treatment.
