Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Background: Congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000, and even more common in some populations. Do carriers have a survival advantage?Objective and hypotheses: The HPA axis has been reported to be more active in CYP21A2 carriers, and possibly enable a more rapid return to homeostasis. A compensatory increase in CRH s...

Introduction: Well-known long-term complications of alloHSCT in childhood include endocrine system damage and secondary malignancies. In addition, adults surviving childhood alloHSCT are at risk of cardiovascular (CV) and metabolic disturbances. Long-term data of physical fitness in correlation with metabolic status are scarce in this particular group.Objective/Patients and Methods: Cross-sectional investigation of exerc...

Background and Methods: PCOS is common in adolescents and imparts a significant health and economic burden. Yet, our understanding of its complex pathogenesis is lacking. Proteomic analyses would be a valuable tool to deepen our knowledge of the biological pathways which underpin PCOS, and to identify novel biomarkers to diagnose and monitor this common condition. Therefore, we undertook a deep phenotyping discovery proteomic profiling (nano-2D-LC-QTOF MSe) on...

Background: Polycystic ovarian syndrome (PCOS) is common, affecting up to one-fifth of females. PCOS is associated with significant comorbidity including metabolic dysfunction, pro-inflammation and mood disorders. Despite this, it is poorly understood, and diagnosis and management remain challenging in adolescents. Proteomics enables the better understanding of disease mechanisms and facilitates the identification of novel biomarkers.<st...

Background: Polycystic ovarian syndrome (PCOS) is the most common hormone disorder in adolescent and young adult females, affecting 4–20% of the population. PCOS is associated with metabolic dysfunction, pro-inflammatory processes and mood disorders. Despite this, it is poorly understood in younger adolescents, and diagnosis and management remain challenging.Objectives: To better understand the clinical phenotype of PCOS in adolescents. Subsequently...

Background and Methods: PCOS is common and associated with significant comorbidity. However, its pathogenesis is complex and poorly understood. We have developed new methods for deep phenotyping discovery proteomic profiling of urine, aiming to identify disease mechanisms, drug targets and novel non-invasive biomarkers for PCOS in adolescents. Here, we present the baseline proteomic data from our prospective, longitudinal study (n=40). We undertook proteomic analysis ...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...

Background: Anogenital distance (AGD) is an indicator of androgen action in utero. Reduced AGD has been found in males with hypospadias, cryptorchidism, low semen quality and infertility. Its usefulness as a clinical marker in patients with Disorders of Sex Development (DSD) is currently being investigated. However, detailed age, sex and method related reference ranges do not exist. Whether individual (body-size-adjusted) AGD is stable postnatally also remains to be e...

Background: FSH stimulates ovarian follicle maturation and estradiol synthesis which is responsible for breast development. Age at pubertal onset varies substantially among healthy girls. Although more than half of the variation is heritable, only a small part has been attributed to specific genetic polymorphisms identified so far.Objective and Hypotheses: We assessed the effect on pubertal onset of three genetic polymorphisms affecting FSH action.<p...
