Serum steroid metabolome dynamics during infancy: a prospective, longitudinal cohort of healthy boys

Siegfried Busch Alexander , Lindhardt Ljubicic Mariee , N. Upners Emmie , B. Fischer Margit , P. Hagen Casper , Frederiksen Hanne , Juul Anders

Background: The circulating steroid metabolome in boys undergoes significant changes during infancy reflecting functional and structural rearrangements of the adrenal glands as well as the transient activity of the hypothalamic–pituitary–gonadal axis, also called minipuberty. Studies investigating the serum steroid metabolome dynamics during infancy in a longitudinal manner are however sparse.Objective: We ai...

Are pappalysins and stanniocalcins involved in modifying the bioavailability of IGF-I in children with onset of type 1 diabetes mellitus?

Güemes Maria , Canelles Sandra , Martín-Rivada Álvaro , Corredor Beatriz , Barrios Vicente , Argente Jesús

Introduction: Both poor and optimal metabolic control of type 1 diabetes mellitus (T1DM) in children can impact longitudinal growth. A decrease in insulin-like growth factor (IGF)-I and its binding protein 3 (IGFBP3) has been described in these patients. New growth regulatory factors [pappalysins (PAPP-As) and stanniocalcins (STCs)] could modulate the bioavailability of IGFs by regulating the concentrations of intact and free IGFBPs.<str...

Bingöl Aydın Dilek , Tin Oğuzhan , Turan Hande , Bayramoğlu Elvan , Ercan Oya , Evliyaoğlu Olcay

Introduction:Premature adrenarche (PA) is the most common cause of premature pubic and axillary hair growth before the age of 8 in girls. At the time of diagnosis, the height and bone age of the cases with premature adrenarche were determined to be higher than their peers. The long-term effects of advanced bone age on the final length of the cases are controversial. In this study, it is aimed to share the long-term follow-up data of the cases diagnosed with pr...

Longitudinal Changes in Serum DLK1 Concentrations During Minipuberty in Healthy Infant Girls; Association to Changes in Linear Growth and Fat Mass

Vilmann Lea , Siegfried Busch Alexander , Lindhardt Ljubicic Marie , N. Upners Emmie , Bistrup Fischer Margit , P. Hagen Casper , Juul Anders

Background: Growth in infancy is considered primarily to be regulated by nutrition and insulin, whereas less is known about the influence of IGF-I, reproductive hormones and other factors of importance. Recently, paternally inherited genetic defects of DLK1 (Delta-like 1 homolog) were found in girls with central precocious puberty (CPP) with a metabolic phenotype. In addition, low maternal serum DLK1 concentrations were significantly lower in pregnant women wh...

Objective: Secondary osteoporosis has a high rate of accompanying chronic diseases. We aimed to review the clinical and laboratory features, underlying causes, Dual Energy X-ray Absorptiometry (DEXA) results before and after treatment of patients diagnosed with secondary osteoporosis and to determine the relationship between this condition and fracture rates.Methods: This study was designed as a single-center, descriptiv...

Caloric intake of 6 months-12 years old children with Prader Willi Syndrome under growth hormone treatment at a reference center.

Corripio Raquel , Couto Yolanda , Sánchez-Garvín Dunia , Pérez-Sánchez Jacobo , Garcia-Tirado Diana

Introduction: Prader-Willi Syndrome (PWS) is the most frequent cause of genetic obesity. It has been described that these patients require a reduction in caloric intake of 20- 40% compared to general population. Since 2000, with the approval of growth hormone (GH), the evolution of obesity has changed and it seems that caloric requirements could be different.Methodology: Observational, descriptive, cross-sectional and re...

Characteristics, effectiveness and safety data for patients with growth failure treated with recombinant IGF-1 and achieving adult or near-adult height: results from the Increlex® Global Registry

Bang Peter , Ramón Krauel Marta , Maghnie Mohamad , Woelfle Joachim , Sert Caroline , Perrot Valérie , Pennestri Daniele , Polak Michel

Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder. Recombinant human insulin-like growth factor (IGF-1) (rhIGF-1; Increlex® [mecasermin]) replacement therapy is EU and US-approved for treating growth failure due to SPIGFD. The long-term therapeutic objective of rhIGF-1 treatment in SPIGFD is to improve adult height (AH). Objective: to describe the characteristics, safety and effectiveness data ...

Value of antimullerian hormone (AMH) in the diagnosis of precocious puberty: revaluation of the covid-19 post-pandemic cohort

Diez-Lopez Ignacio , Aurora Vilella San Martín Leyre , Sarasua Miranda Ainhoa , San Martin Orayen Amaia , Maeso Mendez Sandra

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: The Global Increlex® Registry (NCT00903110) monitors real-world safety and effectiveness of recombinant human insulin-like growth factor (rhIGF-1; Increlex® [mecasermin]) in severe primary IGF-1 deficiency (SPIGFD). Patient characteristics, effectiveness and safety data from 2008–2023 are described.Methods: Descriptive analyses of registry data from children/adolescents age...

A case of papillary thyroid cancer in a boy with an aggravated heredity for medullary thyroid cancer

B Bricheva Ella , V Nagaeva Elena , M Abdulkhabirova Fatima , M Lapshina Anastasiya , A Mikheenkov Alexander , N Brovin Dmitry , V Bondarenko Ekaterina

Background: Thyroid cancer (TC) caused by germline mutations most often manifests in childhood. Hereditary forms of TC are divided into two groups: non-medullary and medullary thyroid cancer (MTC). A mutation in RET gene can be detected in about 95% of patients with MTC. If a mutation in RET gene is found, prophylactic thyroidectomy is recommended.Aim: To demonstrate the importance of molecular genetic ...
