Background: In a Phase 3 trial in participants with obesity due to Bardet-Biedl syndrome (BBS) and Alström syndrome, setmelanotide was associated with significant reduction from baseline in body weight and hunger at Week 52 (primary endpoint), with outcomes driven by responses in individuals with BBS.Methods: In the same trial (NCT03746522), individuals with BBS or Alström syndrome were randomized and received ...

Background: The SRY protein is a transcription factor that contains a high mobility group (HMG) homeobox domain which possesses sequence-specific DNA binding activity and regulates other genes involved in male sex determination pathway. The majority of the identified mutations occurred within the HMG-box motif. There are few reports of pedigrees with familial transmission.Objective and Hypotheses: To describe a paternally transmitted novel SRY mutation w...

Background: β-thalassemia major (β-TM) is the most common genetically determined chronic hemolytic anemia. Studies reported that patients with β-thalassemia are zinc deficient due to increased utilization of zinc by oxidative stress, increased urinary zinc excretion and sequestration in the liver.The development of abnormal glucose tolerance in β-TM is associated with alteration in oxidant-antioxidant status. Zinc plays an essen...

Background: The majority of children with primary nephrogenic diabetes insipidus grow below the third centile.Objective and hypotheses: Effect of rhGH treatment on growth in a patient with primary nephrogenic diabetes insipidus.Results: The patient is an 11-years and 2 month old Caucasian boy of unrelated healthy parents. At the age of 7 years and 9 month he was admitted to our hospital for evaluation of polydipsia and polyuria. Hi...

Background: The surgical reconstruction of hypospadias is usually performed during the first 2 years of life but little objective data is available to determine its optimal timing. Whereas the no-early surgery option in DSD management is rising, the results of late genital surgery should be evaluated before advocating this attitude.Objective and hypotheses: To evaluate the outcome of hypospadias surgery according to age and to determine if some complicat...

Objective: Cluster analysis of urinary steroid metabolome analysis obtained by gas chromatography-mass spectrometry (GC-MS) for treatment monitoring of infants with classic salt-wasting CAH. Methods: We evaluated metabolome analysis of spot urine samples of 60 young children ≤4 years of age (29 females) with classic CAH due to 21-hydroxylase deficiency treated with hydrocortisone and fludrocortisone. Subjects were divide...

Background: Controlling therapy of infants, especially from neonates onwards, with classic congenital adrenal hyperplasia (CAH) is challenging due to the lack of reference values.Methods: We retrospectively analyzed 158 spot urinary steroid hormone metabolite profiles determined by gas chromatography–mass spectrometry (GC-MS) of 60 infants aged 0–4.2 years with classic 21-hydroxylase deficiency (21-OHD) on hydr...

Neonatal diabetes is characterised by hyperglycaemia in the first 6 months of life. Transient neonatal diabetes (TND) is differentiated from permanent neonatal diabetes by its remission in infancy/early childhood, with possible relapse during adolescence in 50% of the cases. Incidence of neonatal diabetes is thought to range from 1:90,000 to 1:160,000. A gene mutation affecting pancreatic beta cells synthesis/secretion of insulin is present in more than 80% of the cases. Overe...

Background: Silver Russell syndrome (SRS) is a heterogeneous disorder characterised by intrauterine and post-natal growth retardation, relative macrocephaly, protruding forehead, feeding difficulties and body asymmetry. Variants in HMGA2 are a rare cause of SRS and despite strong evidence for the crucial role of HMGA2 in growth regulation, its functional role in human linear growth is unclear.Methods: Patients w...

Background: Treatment of children with classic congenital adrenal hyperplasia (CAH) is a difficult balance between hypercortisolism and hyperandrogenism. Biochemical monitoring of treatment is not well defined.Objective: Retrospective software-assisted analysis of urinary steroid metabolome analysis obtained by gas chromatography-mass spectrometry (GC-MS) for treatment monitoring of children with CAH.<p class="abstex...
