Background: Some patients with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) survive without glucocorticoid treatment, despite low total cortisol levels. This may be caused by accumulating precursor steroids such as 21-deoxycortisol (21DF), which could contribute to the glucocorticoid activity. In addition, these precursor steroids may decrease the cortisol-protein binding, thereby increasing the free (biologically activ...

ACAN Mutations in Short Children Born SGA; Growth Response During GH Treatment with Additional GnRHa, and a Proposed Clinical Scoring System

van der Steen Manouk , Hokken-Koelega Anita C.S.

Background: In children born SGA with persistent short stature, growth hormone (GH) treatment is an approved therapy for increasing adult height (AH). Some SGA children have an advanced bone age (BA) during GH. Heterozygous mutations in the ACAN-gene have been described in children with idiopathic short stature and advanced BA.Objective and hypotheses: To assess growth during GH treatment with additional GnRHa treatment, in children with ACAN-gene mutati...

Pubertal Development During GH Treatment with or without Additional GnRH Analogue Treatment in Short Children Born Small for Gestational Age

van der Steen M , Lem A J , Hokken-Koelega A C S

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

Percutaneous Epiphysiodesis Around the Knee Effectively Reduced Predicted Excessive Final Height. Preliminary Results on Final Height, Complications and Satisfaction in a Large Cohort of Dutch Boys and Girls

Goedegebuure Wesley , van der Steen Marieke , Jonkers Frank , Bakker-van Waarde Willy , Odink Roelof

Background: Percutaneous epiphysiodesis (PE) around the knee is the treatment of choice in the Netherlands to reduce predicted excessive final height. Studies until now are limited, had small numbers of patients and short follow-up periods.Objective and hypotheses: This nationwide Dutch long-term retrospective follow-up study aimed to assess final height (FH), complications and satisfaction after PE. Primary hypothesis was: ‘The PE around the knee i...

Cerebral white matter hyperintensities in young adults born small for gestational age treated with growth hormone during childhood in comparison with untreated controls

Dorrepaal Demi , Goedegebuure Wesley , Bos Daniel , van der Lugt Aad , van der Steen Manouk , Hokken-Koelega Anita

Background: The French population of the SAGhE study showed an increased morbidity and mortality due to cerebrovascular disease in growth hormone (GH) treated subjects compared to the general population. Cerebrovascular health can be assessed using neuroimaging markers on MRI. One of the markers is white matter hyperintensity (WMH).Objective: To assess cerebrovascular health by scoring WMH on MRI in young adults born sma...

Long-Term Insulin Sensitivity and β-Cell Function in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

van der Steen Manouk , Lem Annemieke J , van der Kaay Danielle C M , Hokken-Koelega Anita C S

Background: Pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (2 years GnRHa) and even more so with 2 mg/m2 per day (~0.067 mg/kg per day). Concerns haven been raised about the effects of GH and GnRHa on insulin sensitivity on the long-term.Objective and hypotheses: To ...

Long-term GH-treatment of children born small for gestational age (SGA) does not result in cerebrovascular abnormalities in adulthood compared to untreated controls

Dorrepaal Demi , Goedegebuure Wesley , Smagge Lucas , van der Steen Manouk , van der Lugt Aad , Hokken-Koelega Anita

Background: Increased cerebrovascular morbidity and mortality was reported in adults who were treated with growth hormone (GH) during childhood, including those born SGA, compared to the general population. However, previous studies did not have an appropriate control group of untreated SGA adults which was a major limitation.Objective: To assess cerebrovascular abnormalities (aneurysms, previous intracerebral hemorrhage...

Evaluation of health-related quality of life & problem behavior in adults born small for gestational age treated with growth hormone during childhood in comparison with untreated controls

Dorrepaal Demi , Wesley Goedegebuure , der Steen Manouk van , Anita Hokken-Koelega

Background: Being born small for gestational age (SGA) has been associated with a reduction in health-related quality of life (HRQoL) and more problem behaviour. Growth hormone (GH) treatment, which leads to a significant improvement in adult height (AH), improves HRQoL and decreases problem behavior in SGA children. However, such results are very limited in SGA adults who were treated with GH during childhood.Objective:...

Health-Related Quality of Life and Psychosocial Functioning in Young Adults Born SGA after GH/GnRHa Treatment

Goedegebuure Wesley , van der Steen Manouk , de With Justine , Hokken-Koelega Anita

Background: Being born small for gestational age (SGA) has a negative effect on health-related quality of life (HRQoL) and self-perception. This might be more negatively influenced by postponement of puberty using additional gonadotropin-releasing hormone analogue (GnRHa) treatment.Methods: 154 adolescents born SGA participating in a large Dutch growth hormone (GH) trial (75 with 2 years of GnRHa-treatment) completed the TNO-AZL Adults Quality of Life qu...

Longitudinal Study on Body Composition, Insulin Sensitivity and β-cell Function in SGA Adults from Stop of Long-term GH Treatment until 5 Years after Stop

van der Steen Manouk , Kerkhof Gerthe F. , Hokken-Koelega Anita C.S.

Background: GH treatment results in a decrease in fat mass (FM) and insulin sensitivity (Si), and an increase in lean body mass (LBM). Only limited data are available on the longitudinal changes after discontinuation of GH treatment in SGA adults, aged 21 years.Objective and hypotheses: To assess longitudinal changes in body composition (BC) and glucose homeostasis after stop of GH treatment in SGA adults.Method: 197 previously GH-...
