A Rare Case of Pseudoisodicentric X Chromosome in a Patient with Primary Amenorrhoea

Schipper Saskia , Aarts Coranne , van der Linde Annelieke

Background: Pseudoisodicentric X chromosomes with an Xq deletion (46,X,idic(Xq)) are rare. Most cases are mosaic, the other cell line being 45,X. Nonmosaicism is rare. Phenotype is characterized by the resultant of the X deletion. Variations from short to tall stature can occur and premature ovarian failure is a common feature.Case presentation: A 16 year old girl was referred to our clinic with primary amenorrhoea. She ...

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...

Be Aware of Congenital Panhypopituitarism in Children with a Family History of Polydactyly

Hovinga Idske Kremer , Giltay Jacques , van der Kamp Hetty

Background: Congenital panhypopituitarism is associated with a variety of gene mutations. Abnormalities in the Gli2 gene were only recently described to be associated with congenital panhypopituitarism (Franca et al. 2010). Gli2 is a gene that encodes a transcription factor downstream of the Sonic Hedgehog pathway – known to play an important role in morphogenesis during embryology.Objective and hypotheses: Although Gli2 mutations were described to ...

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...

Cardiovascular risk profile in adult patients with congenital adrenal hyperplasia: a cross-sectional study

van der Zwan Y.G. , Schrӧder M. , Stikkelbroeck N.M.M.L. , Reisch N. , Falhammar H. , Roeleveld N. , Claahsen-van der Grinten H.L.

Background: Adults with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD) develop an adverse metabolic and cardiovascular risk profile. Both over- and undertreatment with glucocorticoids are associated with these adverse metabolic effects. There is limited data available of changes in cardiovascular parameters during lifetime.Objective: This study aimed to evaluate unfavorable changes in cardiovascu...

Results of Exome Sequencing in Disorders of Sex Development

Kempers Marlies , Claahsen Hedi , Alfen Janielle van , Velden van der , Rinne Tuula

Disorders or Differences of sex development (DSD) are a heterogeneous group of congenital conditions, involving variations of chromosomal, gonadal, or anatomical development. Diagnosis is based on clinical, biochemical, imaging and genetic evaluation. In recent years knowledge about genetic causes has increased, mainly due to improved genetic techniques. In this study we investigated the yield of exome sequencing in our patients with DSD. Patients and methods: Genetic i...

Cut-Off Values for Nocturnal Salivary Testosterone to Enable Detection of Early Puberty

van der Sande Linda J.T.M. , van den Hoogen Chris J. , Boer Arjen-Kars , Odink Roelof J.

Background: In boys with suspected delayed puberty, serum testosterone is used for the evaluation of gonadal function. It is known that early in puberty testosterone levels show a sleep wake rhythm, with nocturnal levels increasing ahead of daytime levels. To evaluate the onset of puberty, the use of salivary testosterone would be an appealing alternative to serum analysis as it is non-invasive and allows multiple nocturnal sampling. Moreover, it is thought that salivary testo...
