Effects of burosumab treatment on mineral homeostasis in children and adolescents with X-linked hypophosphatemia: lessons from the German XLH Registry

Ewert Annika , Rehberg Mirko , Hiort Olaf , Binder Gerhard , Schröder Carmen , Jorch Norbert , Richter-Unruh Annette , Freiberg Clemens , Peter Schlingmann Karl , Haffner Dieter , Schnabel Dirk

Introduction: Burosumab was approved for treatment of pediatric patients with X-linked hypophosphatemia (XLH). However, data on its efficacy in adolescents (age > 12 years) and in real-world settings are lacking.Material and methods: Here we assess the effects of 12 months burosumab treatment on mineral homeostasis in 77 pediatric XLH patients (50 children, 27 adolescents) enrolled in the German XLH Registry. Age and ...

Background: Measurement of testicular volume is important when conditions associated with a delay or advance in the onset of puberty, or micro- and macroorchidism, are suspected. Measured testicular volumes must be compared with reference data, preferably expressed in S.D. curves using the LMS method, as is routinely done for many auxological measurements in pediatrics. The current study therefore aimed to construct LMS-smoothed age-reference charts for testicul...

Pathogenic variants in GHSR cause short stature and growth hormone neurosecretory dysfunction; results from a large case series

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Nephrogenic Syndrome of Inappropriate Antidiuresis (NSIAD) Managed with Fluid Restriction and Salt Supplementation

Amato Lisa A , Verge Charles F , Walker Jan L , Neville Kristen A

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Effect of serum TSH level on ovarian volume in prepubertal girls with subclinical hypothyroidism

Yigit Özgül , Sert Tugba , Ekinci Deniz , Kirankaya Aysegül , Kilinç Suna

Background and Objectives: Enlargement and cystic changes in ovaries of patients with longstanding overt hypothyroidism has been observed in numerous case reports. But there is limited data about the effect of subclinical hypothyroidism (SH) on ovarian volume and ovarian cyst formation. We evaluated the relationship between serum thyroid stimulating hormone (TSH) level and ovarian volume and sonographic appearance in prepubertal girls with SH.<p class="abs...

Van Duyvenvoorde Hermine , De Bruin Christiaan , Hwa Vivian , Klonisch Thomas , Hombach-Klonisch Sabine , L. Storr Helen

Background: Silver Russell syndrome (SRS) is a heterogeneous disorder characterised by intrauterine and post-natal growth retardation, relative macrocephaly, protruding forehead, feeding difficulties and body asymmetry. Variants in HMGA2 are a rare cause of SRS and despite strong evidence for the crucial role of HMGA2 in growth regulation, its functional role in human linear growth is unclear.Methods: Patients w...

Relation Between CNP Signaling Pathway and the Effect of Combined Treatment with GnRHa and rhGH on the Linear Growth in Mid/Late Pubertal Girls at Great Bone Ages with CPP or EFP

M A Hua-mei , S U Zhe , L I Yin-ya

Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...

Bone Mineral Density (BMD) in Women with Turner Syndrome (TS) from the DSD-LIFE Cohort, an Epidemiological Study

Pienkowski Catherine , El Allali Yasmine , Cartault Audrey , Ernoult Perrine , Grunenwald Solange , Reish Nicole , Claahsen-Van Hedi , Salles Jean-Pierre

Aim: The objective of the study was to determine bone mineralisation density in Turner syndrome (TS) from DSD life cohort, and to analyse the trabecular (lumbar spine = LS) and cortical bone (femoral neck = FN) mineralisation.Materials and Methods: This study was part of the DSD-LIFE study, a cross-sectional clinical outcome study of the BMD of TS adult patients from paediatric cohorts. BMD of the LS and FN were ...

Long Term Comparison between Liquid and Tablet Formulations of L-Thyroxine (L-T4) in the Treatment of Congenital Hypothyroidism (CH)

Introduction: Few studies have been published comparing the liquid and tablet formulations of L-T4 in pediatric patients, with a short follow-up period. Both formulations seemed to produce a rapid normalization of thyroid fuction with a tendency of a greater TSH inhibition in children taking the L-T4 liquid drops. The aim of our study is to compare the long-term effectiveness and saftey of both liquid and tablet L-T4 therapy in CH patients up to 3 years old via a multicenter s...
