Childhood onset of growth hormone deficiency (GHD) is a clinically heterogeneous condition and defining its cause is important for diagnostics and treatment. The most common genes implicated in the genetic etiology of growth hormone deficiency (GHD) are GH1 (MIM: 139250), encoding growth hormone (GH), and GHRHR (MIM: 139191), encoding the receptor for GHRH. GHD may also result from mutations in genes that encode transcription factors involved in pituitary dev...

Introduction: Human newborn(NWB) respiratory derangements may be concomitant to oral/enteral caloric intake (KOE) insufficiency. We evidenced a possible involvement of axillary temperature(TEMP) in relationships between preterm birth (PTB) and blood serum Insulin-like Growth Factor-I(IG1) in NWBs. Here we evaluate the TEMP-independent role of birth gestational age(GA) and KOE in relations of O2 supplementation in respiratory gases(O2S) to IG1 in the not-life-t...

In XLH, excess fibroblast growth factor 23 (FGF23) causes hypophosphatemia and consequent rickets, skeletal deformities, and growth impairment. The efficacy and safety of burosumab, a fully human monoclonal antibody against FGF23, was evaluated in two Phase 2 trials in children with XLH. In CL201, 52 children with XLH (5–12 years old, Tanner ≤2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) weeks, with doses titrated up to 2 mg/kg to...

With the increased number of patients with diabetes on one hand and the shortage of professional teams of health care providers (HCP) worldwide on the other hand, new ways of providing medical care to patients with diabetes are needed. Decision Support Systems (DSS) and emerging tools are developed in order to help HCP during patients’ office visits and to help patients navigate their own metabolic control between office visits. Recently, tools of DSS have been tested in ...

Background: BRAF is a component of the RAS/MAPK signalling pathway; germline mutations in components of this pathway are associated with congenital abnormalities such as Cardio-Facio-Cutaneous (CFC), Noonan and Costello Syndromes. These syndromes, known as RASopathies, are characterised by variably penetrant central nervous system, cardiac and facial abnormalities. Importantly, short stature and delayed puberty have been associated with these syndromes, as have featur...

The McCune–Albright syndrome can be a disease of striking complexity, the management of which can be challenging. However, an understanding of the physiologic consequences of the underlying molecular and developmental biology makes the evaluation and treatment of this disease relatively straightforward. MAS arises from activating mutations in the ubiquitously expressed cAMP-signaling protein, Gsα. The mutations occur very early in development, prior to gas...

Approximately 25 of 100 000 children are born with an atypical appearance of their genitalia as part of a more or less defined disorder of sex development (DSD). Due to improved medical knowledge and better classification, the aetiology and pathophysiology behind a growing number of these cases have been clarified, although a large number still remains obscure with respect to the underlying biology. In line with this, there are growing insights into the functional consequences...

Objectives: In X-linked hypophosphatemia (XLH), abnormally elevated serum Fibroblast growth Factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption, low serum phosphorus, inappropriately normal 1,25-dihydroxyvitamin D, and development of rachitic deformities. The effect of KRN23 on health-related quality of life (HRQL) was assessed.Methods: Open-label KRN23 was given s.c. every 28 days up to four doses to 28 adults with XLH (2...

Background: In X-linked hypophosphatemia (XLH), abnormally elevated serum fibroblast growth factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption (TmP/GFR), low serum phosphorus (Pi), inappropriately normal 1,25-dihydroxyvitamin D (1,25(OH)2D) and development of rachitic deformities.Methods: Up to four s.c. KRN23 doses were given every 28 days to 28 adults with XLH according to a dose-escalation algorithm (0.05&#1...

Pancreatic β cells develop from endodermal pancreatic progenitors that first proliferate and next differentiate into functional insulin-producing cells. This developmental process is complex, each step being controlled by yet unknown signals. Theoretically, the development of a functional β cell mass can be enhanced by: i) activating the proliferation of pancreatic progenitors; ii) activating their differentiation into β cells; iii) activating the proliferation ...
