Background: XLHR is due to mutations in the PHEX gene leading to unregulated production of FGF23, hence hypophosphatemia and decreased renal 1,25OH-vitamin D hydroxylation. Amongst other features, XLHR is characterized by leg bowing of variable severity. Phosphate supplements and oral 1,25OH-vitamin D, partially or, in some cases, fully restore the limb straightness. For severe or residual limb deformities, orthopaedic surgery may be recommended.Objectiv...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Background: Hereditary Hypophosphatemic Rickets (HHR) is caused by persistently elevated FGF23 resulting in renal phosphate wasting and decreased 25 vitamin D hydroxylation. Treatment with vitamin D analogues (VDA) has been added to phosphate supplements in the late seventies.Objective and hypotheses: Our objective was to evaluate the outcomes of VDA and phosphate supplements in adult patients with HHR in comparison with patients who did not receive VDA ...

Benign breast diseases (BBD) have always been neglected in comparison to cancer, despite the fact that there are many more patients with such diseases than patients presenting to a breast clinic for cancer, especially in young women. So far, BBD have been the subject of a relatively few isolated and unconnected studies, and earlier related work has often been ignored. This situation has led to a great deal of confusion, especially because different authors have their own nomen...

Primary (premature) ovarian insufficiency (POI) is defined as a loss of ovarian activity before the age of 40, and is characterized by menstrual disturbances (amenorrhea or oligomenorrhea) with elevated gonadotropins (follicle-stimulating hormone [FSH] ≥ 25 IU/L) and low serum estradiol levels. The incidence of POI is around 1 per 100 women overall, and 1 per 1000 women under the age of 30 years. POI leads to infertility and an increased risk of osteoporosis and cardiova...

Patients with Turner syndrome (TS) have short stature, despite having normal growth hormone (GH) secretion. Treatment with recombinant human GH is recommended. The effectiveness and safety of Norditropin® (somatropin, Novo Nordisk) over ≤10 years of follow-up were investigated in two non-interventional studies: NordiNet® IOS (NCT00960128) and the ANSWER Program (NCT01009905). Of 2,409 children with TS, 2,377 were included in the full analysis s...

Aims: Recently, our team introduced the concept of post-hypoglycemic hyperglycemia (PHH) in the context that recovery of hypoglycemia impacts cardiovascular risk. GLUREDIA study aimed to evaluate whether PHH parameters correlated with glycemic homeostasis during the first year after type 1 diabetes onset and helped to distinguish pediatric patients undergoing partial remission or not.Methods: In the GLUREDIA study, longi...

Adult reproductive function is affected by early life environments and experiences, pointing to a possible role for epigenetic modifications in directing an adaptive response. Using mouse and cellular models, we have been studying the mechanisms underlying the shorter reproductive lifespan experienced by Bangladeshi women who grew up in Bangladesh as opposed to the UK, a phenotype associated specifically with the greater immune challenges in Bangladeshi childhood and altered D...

Type 1 diabetes (T1D) is a chronic disease characterized by the autoimmune destruction of pancreatic β cells. This destruction is mediated by lymphocytes T helper and cytotoxic, and by the action of the pro-inflammatory cytokines IL1β, IFNγ and TNFa inside the islets of Langerhans. We propose a new approach to alleviate islet inflammation by targeting pro-inflammatory cytokine receptors. Our hypothesis is that the downregulation of inflammatory pathways ma...

Background and Aims: Despite intensive insulin treatment of type 1 diabetes (T1DM), metabolic control remains suboptimal, especially in children. In an attempt to optimize postprandial glycaemia, some families decrease the amount of carbohydrates contained in a meal. While "low-carbohydrate diets" may improve metabolic control in some selected populations, controversies remain around the risk of hypoglycemia and ketoacidosis and the impact of such diet...
