Background: Studies in young mammals on the qualitative and quantitative molecular effects of food restriction (RES) and re-feeding, leading to catch up growth (CU) are scarce. Whereas RES may lead to growth and developmental deficits in children, it is a proven treatment to prolong life in all animals checked.Objective and hypotheses: We used MS analysis to understand how RES might lead to growth attenuation and prolonged life span and identify the majo...

Background: Recently, patients with severe obesity have been described due to functional leptin deficiency. This new entity is characterized by high immunoreactive levels of circulating leptin (Lep), but a reduced bioactivity of the hormone due to defective receptor binding (N Engl J Med 2015;372:48–54). Since these patients can be successfully treated with human recombinant leptin (metreleptin), a diagnostic tool to detect functional leptin deficiency is needed.<p cl...

Background: Obesity is a persistent disorder that almost universally recurs following treatment, suggesting a disruption on central nervous system control over energy homeostasis. Recent literature suggests that hypothalamic inflammation may have an important role on obesity pathogenesis. This inflammatory reaction, which histologically appears as a reactive gliosis, may be detected using magnetic resonance imaging (MRI), and has just been shown in rodent models and adults.</p...

Background: The duodenal-jejunal bypass liner (DJBL) is an endoscopically placed and removable bariatric device associated with weight loss and metabolic improvements in adults.Objective and hypotheses: To determined efficacy and safety of DJBL up to 1 year in morbidly obese adolescents.Method: About 14 obese adolescents with prediabetes or type 2 diabetes (10 female, mean (SD) age 17.7 (1.1) years) underwent endoscopic placement o...

Background: Prader-Willi syndrome (PWS) is a rare genetic disorder characterized by hyperphagia and abnormal behaviours towards food for both of which no approved treatment is available. Elevated plasma acylated ghrelin (AG) documented at all ages in PWS suggest that the ghrelin system may contribute to the pathophysiology of hyperphagia. Administration of unacylated ghrelin and 8-amino acid analog AZP-531 prevents AG-induced food consumption in animals and improves glucose co...

Background: POMC deficiency is an extremely rare monogenetic obesity syndrome generally characterized by early onset hyperphagia, red hair and adrenal insufficiency. So far treatment of obesity and hyperphagia with MSH substitution failed, either due to ineffectiveness or side effects of available MC4R agonists.Objective and hypotheses: We hypothesized that the new MC-4R agonist setmelanotide might be a treatment option in POMC deficient patients.<p ...
