Background: Despite the fact that pituitary stalk interruption syndrome (PSIS) is a frequent finding in children with combined GH deficiency (CGHD), clinical data are still limited and the growth response to GH treatment has not been evaluated in comparison with CGDH with a normal stalk.Objective and hypotheses: To report the clinical and hormonal findings and evaluate the short term growth response to GH in Belgian children with congenital non-syndromat...

During the pandemic, an increase in the cases of premature thelarche consultations was observed. Our group published a series in 2021 of 75 cases. This effect could have been caused by an increase in body fat mass in girls, suggesting a “trigger effect” in the activation of the gonadal axis, causing an increase in the number of cases of early puberty (SEEP Oviedo 2022). AMH has been correlated as a predictor of the moment of menarche (doi: 10.1515/jpem-2014-0521)</...

Background: In a large fraction of patients with clinically presumed Androgen Insensitivity Syndrome, no mutation of the Androgen Receptor gene can be detected. However, established Sanger sequencing techniques of the AR gene are often limited to the coding region.Objective and Hypotheses: To set up a next generation sequencing (NGS) approach of the entire AR locus (including UTRs, exons, introns, up- and downstream regions) for a comprehensive ...

Background: Partial Androgen insensitivity syndrome (PAIS) is a rare condition which is associated with a variable phenotype. To date, there are limited data reporting long-term endocrine outcome for this condition.Aims: To determine the outcomes and clinical characteristics for 46, XY males with PAIS, using information from the International DSD (I-DSD) Registry and its clinical users.Methods: The I-DSD Registry and its users were...

Background: It is well known that boys are heavier than girls at birth. Causes of this difference are thought to originate from the Y chromosome and as a result of androgen action. Although some studies showed that sex dimorphism in size at birth is dependent of fetal androgens, one study reported that it is not generated by action of androgens.Objective and hypotheses: To determine birth weight (BW) of children in different aetiologies of disorder of se...

Background and Aim: A substantial proportion of SGA patients have a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic (S-SGA) and non-syndromic patients (nonS-SGA) impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of the Belgian SGA cohort and analyze rhGH response based on adult height (AH).Patients & Methods: Cli...

Background: Reaching a definitive diagnosis in individuals with XY DSD is challenging and the time taken to reach a diagnosis is an important clinical benchmark that has not been sufficiently explored in this group of conditions.Objective: To evaluate the diagnostic process with a focus on the time to diagnosis in children with XY DSD reported via the e-reporting platform (e-REC) of the European Registries for Rare Endoc...

Background: A combination of GH and a gonadotropin releasing hormone analogue (GnRH a) is hypothesized to improve adult height in children with a poor adult height prediction.Study design: In this multicenter study, 24 girls in early puberty (bone age ≤12.0 y),with a predicted adult height ≤151.0 cm and normal body proportions were treated with GH (Zomacton) 50 μg/kg per day and triptorelin (Gonapeptyl) 3.75 mg/month SC or IM (for 4 year...

Background: A combination of GH and a GnRH agonist is sometimes used to improve adult height in children with a poor height prediction, only few studies support this.Study design: In this multicenter study, 24 short girls in early puberty, with a bone age below 12.0 years, an adult height prediction below 151.0 cm and normal body proportions were treated with GH (Zomacton) transjections 50 μg/kg per day and triptorelin (Decapeptyl) i.m. (3.75 mg/mon...

Background: Gonadectomy is generally postponed until early adulthood in complete androgen insensitivity syndrome (CAIS) and close surveillance of gonads in situ proposed in males with partial AIS (PAIS). Delaying gonadectomy further is controversial given the lack of data regarding germ cell cancer (GCC) development in adulthood and the absence of biomarkers for noninvasive GCC screening.Aims and objectives: To study the prevalence of invasive G...
