The use of intestinal organoids to investigate nutrient sensing

Ramgulam Anya , Gonzalez-Abuin Noemi , Frost Gary , Murphy Kevin

Intestinal nutrient sensing and transport are gaining increasing attention in the field of obesity research. To date, in vitro studies in this area have largely used two dimensional (2D) cell culture models. However, 2D cell cultures are limited by a lack of cellular heterogeneity, behaviour, and communication observed in vivo. There has consequently been growing interest for the application of three-dimensional (3D) cell culture ...

Investigating the role of the gut metabolome in appetite and obesity

Stephens Hannah , Ramgulam Anya , Franco-Becker Georgia , Tashkova Martina , Serrano Contreras Jose Ivan , Blunt Dominic , Garcia-Perez Isabel , Frost Gary , Murphy Kevin

Overweight and obesity is an escalating global health problem, affecting 40% of the population and being the 5th largest cause of death worldwide. Treatment options are limited, with pharmaceutical approaches being inadequate and the success of bariatric surgery being limited by its invasive nature. The regulation of appetite by small bioactive compounds in the gastrointestinal tract is an important target in antiobesity research. Metabolites from diet and both host and microb...

Pseudohypoparathyroidism: focus on neonatal features, preliminary data from a retrospective analysis of a large cohort of patients

Del Sindaco Giulia , Pagnano Angela , Berkenou Jugurtha , Rothenbuhler Anya , Arosio Maura , Linglart Agnes , Mantovani Giovanna

Since the first description of pseudohypoparathyroidism (PHP) a remarkable clinical variability was observed. In 2016 a new classification of this group of diseases have been published by the European Network on PHP and related disorders, proposing “inactivating PTH/PTHrP signaling disorder” (iPPSD) as a new term that encompasses all the clinical entities. PHP and related disorders vary in clinical presentation and disease severity, and clinical features usually deve...

Clinical picture of early infancy PTH-resistance syndromes: is it time to improve diagnostic criteria?

Del Sindaco Giulia , Pagnano Angela , Berkenou Jugurtha , Ferrante Emanuele , Rothenbuhler Anya , Arosio Maura , Mantovani Giovanna , Linglart Agnes

Since the first description of inactivating PTH/PTHrP signaling disorders (iPPSDs, historically named pseudohypoparathyroidism (PHP)) a remarkable clinical variability was observed, especially in clinical presentation, which seems to be age-dependent. The main clinical features, including PTH resistance, brachydactyly and short stature, develop during mid and late childhood, whilst minor clinical features such as a round face, rapid weight gain and subclinical hypothyroidism a...

Prospective evaluation of endocrine complications in adults with X-linked hypophosphatemic rickets

Kamenicky Peter , Boros Emese , Rothenbuhler Anya , Brailly Sylvie , Silve Caroline , Souberbielle Jean-Claude , Chanson Philippe , Linglart Agnes

Objectives: X-linked hypophosphatemic Rickets (XLHR) is characterized by phosphate wasting and decreased production of 1,25OH-vitamin D, due, in most patients, to elevated FGF23 and PHEX mutation. In children, the disease has been extensively studied because of the devastating presentation of rickets, teeth abcesses, and growth retardation. In adults, however, metabolic complications, such as hyperparathyroidism or consequences on glucose and lipid metabolism of FGF23 excess, ...

Increased prevalence of overweight and obesity and its clinical predictors in children affected by x-linked hypophosphatemia

Zhukouskaya Volha V. , Rothenbuhler Anya , Colao Annamaria , Di Somma Carolina , Kamenicky Peter , Trabado Severine , Prie Dominique , Audrain Christelle , Barosi Anna , Kyheng Christele , Lambert Anne-Sophie , Linglart Agnes

Background/aim: X-linked hypophosphatemia (XLH) is a rare disease characterized by low phosphate level. Scientific evidence points to link between hypophosphatemia and obesity in general population. The aim of our longitudinal observational study was to investigate the prevalence of obesity and associated factors in a large cohort of children with XLH.Patients/methods: We selected 172 XLH-children of 5-20 years (113 girls/59 boys). Anthropometric paramet...

Hyperparathyroidism in patients with X-linked hypophosphatemia

Lecoq Anne-Lise , Chaumet-Riffaud Philippe , Blanchard Anne , Rothenbuhler Anya , Lambert Benoit , Bay Alexandrine , Silve Caroline , Piketty Marie , Chanson Philippe , Brailly-Tabard Sylvie , Linglart Agnes , Kamenicky Peter

Background: X-linked hypophosphatemia (XLH) is a rachitic disorder characterized by renal tubular phosphate wasting resulting from increased circulating activity of the fibroblast growth factor FGF23. Secondary and tertiary hyperparathyroidism have been reported in XLH patients in small retrospective studies, however this complication has never been systematically evaluated in a large cohort.Aim of the study: To compare parathyroid function of adult XLH ...

Higher dose of burosumab is needed for treatment of children with sever forms of X-linked hypophosphatemia

Background/aim: Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for the treatment of X-linked hypophosphatemia (XLH). Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of the present study.Patients/methods: Thirty-nine children with XLH were switched from conventional therapy to burosumab (starting dose 0.4 mg/kg), on the basis of following indications: non-resp...

Real-life clinical study: 1-year of treatment with burosumab of children and adolescents affected with X-linked hypophosphatemia

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by PHEX mutation, leading to elevated FGF23, renal phosphate wasting, hypophosphatemia, insufficient 1,25(OH)2D synthesis. Clinically, it manifests with rickets including leg deformities, poor growth, dental abscesses, craniosynostosis, and hearing loss. Beyond conventional treatment (phosphate supplements + active vitamin D), burosumab is pathogenetic anti-FGF23 therapeutic approa...
