Background: Congenital leptin deficiency (CLD) is characterized by severe early-onset obesity due to hyperphagia and impaired satiety. The impact of obesity in obstructive sleep apnoea hypopnoea syndrome (OSAHS) was originally reported as mechanical, but recent data suggest that adipokines may influence central ventilation. We highlight that treatment with recombinant human leptin (RHL) in CLD with OSAHS improves ventilation before weight loss.Case prese...

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

Background: Prader-Willi syndrome (PWS), caused by loss of paternally imprinted genes in the 15q11-13 region, results in hypogonadism which is more severe in males.Objective: To review the gonadal status of patients seen in a dedicated PWS clinic from 1990–2013 inclusive so as to establish the clinical patterns and hence to optimise future management.Method: Retrospective case note review over a 23-year period.<p class="ab...

Background: Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome. Accelerated catch-up in weight during infancy in subjects born term has been associated with increased risk for NAFLD in adulthood, but this association has not been studied in subjects born preterm.Objective and hypotheses: To investigate the associations of birth weight, gain in weight for length and accelerated catch-up in weight in the...

Background: In contrast to hypoglycaemia due to congenital hyperinsulinism, there are patients with a similar metabolic profile of hypoketotic hypoglycaemia, but low insulin levels and relatively low glucose requirements to maintain euglycaemia. So far, four patients with activating mutations in the insulin signal-transducing kinase AKT2 have been described, each also showing a syndromic phenotype including hemihypertrophy.Objective and hypotheses: We pr...

Background: Studies have shown that genetic variations in the FSH pathway (SNPs: FSHB −211G>T, FSHR −29G>A, and FSHR 2039A>G) affect peripubertal levels of serum FSH and age at pubertal onset in girls.Objective and hypotheses: Genetic variations in the FSH pathway reflect circulating levels of female reproductive hormones during the postnatal gonadotropin surge.Method: Blood samples were taken in girls of th...

Background: Although the clinical presentations of congenital adrenal hyperplasia (CAH) have been studied in Saudi children, the literature review revealed no molecular report of 21-hydroxylase was published.Objective and hypotheses: The aim of this study was to determine the pattern of CYP21A2 gene-mutations of CAH in Saudi children.Method: Between January 2011 and March 2014 at King Fahad Military Complex, Dhahran, Saudi Arabia, ...

Background: In type 1 diabetes (T1D) adolescents it is necessary to design effective interventions to take care of their health and psychological problems. This leads to effective transition to an adult unit.Objectives: Evaluate the relationship of lifestyle with metabolic control in diabetic adolescents.Methods: Retrospective study of 42 T1D adolescents managed in a Pediatric Diabetes Unit. Patients completed a questionnaire on li...

Background: Over the last years a role for gastrointestinal hormones, such as glucagon-like peptide (GLP-1), in the pathogenesis of obesity and its complications, has been hypothesized. However, there are few data for the paediatric population.Objective and hypotheses: To assess whether there is a difference in post-load GLP-1 response in obese children compared to normal-weight peers and to assess the relationship with insulin responses.<p class="ab...

Background: IGF1 measurements are used to diagnose and monitoring GH related disorders. GH dose is titrated against IGF1 concentrations which should be kept within the age-and sex-related normal range. However, IGF1 results vary widely depending on the immunoassay used. International guidelines advise to report IGF1 results as S.D. scores from an assay-specific age-related reference population.Objective and hypotheses: Our objective was to...
