Scientific titleBrain Development after prenatal growth retardation: effects of growth hormone treatment
Study acronymSGA Brain Development study
Study objectivesThis study aims to evaluate the effect of growth hormone treatment on brain functioning and development in children born with a low birth weight/length with incomplete catch up growth.

The two other hypotheses this study aims to evaluate are:
1. Is there a difference in brain functioning in children born with a low birth weight/length between those without and with complete catch up growth?
2. Will intra-uterine growth failure affect brain development/functioning?
Ethics approval(s)Approval received from the Medical Ethics Review Committee of de Vrije Universiteit medical centre, Amsterdam on the 1st March 2007 (ref: 06/279).
Health condition(s) or problem(s) studiedSmall for Gestational Age (SGA), brain development
InterventionStructural (only at baseline) and functional MRI’s, MEG and extensive neuropsychologic testing will be performed at baseline, after one year and three years in both groups A (treatment with growth hormone (somatropin) and B (without treatment).

SGA patients older than six years of age, with incomplete catch-up growth with the indication of GH treatment, will be followed on neuropsychologic functioning.

Hypothesis 2/ 3:
In groups C and D structural and functional MRI’s, MEG and extensive neuropsychological testing will be performed only at start of the study.
Intervention typeOther
Primary outcome measure1. To determine the effect of prenatal growth retardation on brain functioning/development
2. To determine the effect of growth hormone treatment on brain functioning/development in children born after prenatal growth retardation
3. To assess wether there is a difference in brain development in between SGA children with and without postnatal catch up growth
Secondary outcome measuresNo secondary outcome measures

4. Any endocrine or metabolic disorder such as diabetes mellitus, diabetes insipidus, hypothyroidism, or inborn errors of metabolism, except of Growth Hormone Deficiency (GHD)
5. Medications or interventions during the previous six months that might have interfered with growth, such as corticosteroids (including high dose of corticosteroid inhalation), sex steroids, growth hormone, or major surgery (particularly of the spine or extremities)
6. Use of medication that might interfere with growth during GH therapy, such as corticosteroids, sex steroids, Luteinising Hormone-Releasing Hormone (LHRH) analogue
7. Active or treated malignancy or increased risk of leukaemia
8. Serious suspicion of psychosocial dwarfism (emotional deprivation)
9. Severe neurological disability
