Background: Hypophosphataemic rickets is a rare, and challenging condition to diagnose as the biochemical and radiological features are subtle compared with the more common calcipaenic rickets. Retrospective review of 4yr-old girl with PHEX mutation initially managed as Blount’s disease with surgery showed low (0.93 mmol/l), but within reference interval phosphate levels at initial presentation which caused some diagnostic uncertainty. Paediatric phospha...

Background: The natural evolution of euthyroid Hashimoto thyroiditis (HT) varies among children and treatment in children with HT and normal/mild elevated serum TSH is controversial.Objective and hypotheses: The aim was to study the natural course of HT in children and evaluate predictive factors of thyroid functionMethod: We evaluated data from 87 children retrospectively (63 girls, 24 boys), mean age 10.6±3.2yrs, with HT [an...

Introduction: Daily breakfast consumption is recommended as part of a healthy lifestyle in children and adolescents. The present study aimed to report the frequency of breakfast consumption and explore the associations between breakfast consumption and diet quality in children with overweight/obesity.Methods: In total, 1335 children/adolescents 2-18 years old were recruited in a weight-management out-patient clinic in th...

Background: In Romania (latitude 48°15’N to 43°40’N), vitamin D supplementation is a common practice mostly in 0–2 year old infants. No published information is available regarding vitamin D status in Romanian children.Objective and hypotheses: We aimed to evaluate the seasonal and age variation of vitamin D status in a large Romanian pediatric patient population.Method: 1 395 individuals, 0–18years, f...

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

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...

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 SC KRN23 doses were given every 28 days to 28 adults with XLH (26 completed) according to a dose-escalation algorithm (0.05&...

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: Hypophosphatemia due to excess urinary phosphate losses and rachitic bone disease occur in several related disorders. The most common form of the heritable hypophosphatemic disorders, X-linked hypophosphatemia (XLH), is due to loss-of-function mutations of the osteocyte/osteoblast protein, PHEX. Reduced abundance of phosphate transporters on the luminal surface of renal tubular cells in the syngeneic animal model of XLH, and inappropriately normal (or frankly low) ...

Background: Nocturnal hypoglycemia is not regularly predictable on the basis of a bedtime BG level and can only be confirmed by BG tests at regular intervals during the night or continuous glucose monitoring (CGM).Objective and hypotheses: A bedtime snack containing carbohydrate as well as fat and protein may be useful in preventing nocturnal hypoglycemia, but this should not be at the expense of high overnight BG levels. In many individuals, a lowering ...
