Background: Upon excessive expansion, adipose tissue is infiltrated by macrophages and shows increased production of inflammatory cytokines. This chronic low grade inflammation of adipose tissue is involved in the pathogenesis of insulin resistance. A supplementation with resveratrol can reverse the metabolic disturbances of human obesity, in part by mimicking the effects of caloric restriction.Objective and Hypotheses: We hypothesized that the beneficia...

Background: Adult survivors of childhood leukaemia treated Bone marrow transplantation with total body irradiation (BMT/TBI) have an increased risk of diabetes mellitus (DM) disproportionate to their level of adiposity or other recognised risk factors. Post prandial hyperglycaemia due to reduced β-cell reserve after irradiation will be missed by fasting glucose (FG) levels. However, the UK National Institute of Clinical Excellence (NICE) screening guidelines recommend the...

Background: Primary IGF1 deficiency (PIGFD) is a rare disease defined by low IGF1 levels, GH sufficiency and absence of secondary causes of growth failure. Whereas some members of the GH–IGF axis have been shown to be implicated in the severe syndromic forms of PIGFD due to GH insensitivity, genetic causes of less severely affected patients are mostly unknown.Objective and hypotheses: The aim of the present study was to systematically investigate fr...

Background: Tuberous sclerosis (TS) is an autosomal dominant neurocutaneous disorder involving many organ systems. The frequency of TS is around one per 5000 to 10 000 live births and is caused by mutation in the TSC1 or TSC2 genes. Autoimmune polyglandular syndrome type 2 (APS2) is an endocrinopathy characterized by two or more autoimmune diseases. Several susceptibility genes are known. The prevalence of APS2 is around 1:20 000.Object...

Introduction: Standard dose for GH deficient children is 0.025 mg/kg per day given subcutaneously once daily. Inborn panhypopituitarism is a special subset of GH deficiency. Its management is difficult because several hormones need to be replaced. We present three patients with perinatal onset panhypopituitarism.Case reports: Case 1 is a 7-year-old boy who had hypoglycaemic seizure with reanimation due to circulatory arrest shortly after birth. Panhypopi...

Background: Hypophosphatemic rickets (HR) is most commonly X-linked or autosomal dominant, but autosomal recessive (AR) forms have been described. ARHR1 (DMP1) and ARHR2 (ENPP1) share identical biochemical characteristics of excessive renal phosphate wasting due to increased circulating levels of the phosphatonin FGF23 and low serum levels of 1,25(OH)2D. By contrast, in hereditary hypophosphatemic rickets with hypercalciuria (HHRH) phosphaturia is ...

Background: Hypoparathyroidism may manifest either as an isolated disorder or as a component of a more complex syndrome. Molecular genetic studies indicate that mutations in PTH, CASR, GCM2 and GNA11 are causes of isolated hypoparathyroidism (IH) and mutations in GATA3, TBCE, FAM111A, AIRE and TBX1 are associated with different complex syndromes with hypoparathyroidism.Objec...

Background: Hypophosphatasia (HPP) is the rare inherited metabolic disorder resulting from loss-of-function mutation(s) in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. TNSALP deficiency can cause a spectrum of complications in children including premature deciduous tooth loss, rickets, poor growth, and compromised physical function. We previously reported that children, 5–12 years old, with HPP and treated with asfotase alfa, a recombinant bone-targeted huma...

Background: Self-limited delayed puberty (DP) often segregates in an autosomal dominant pattern, suggesting that inheritance is conferred by a small number of genes. However, the underlying genetic background is mostly unknown. By comparison, many genes have been identified where loss-of-function mutations lead to hypogonadotropic hypogonadism (HH). Despite likely overlap between the pathophysiology of delayed puberty and conditions of GnRH deficiency, few studies have examine...

Background: Children with growth hormone deficiency (GHD) may experience physiological symptoms as well as social and emotional problems.Objective and hypotheses: This qualitative study explored the burden of GHD and treatment for children and their parents.Method: 70 interviews were conducted with 39 children (age 8–12) and 31 parents of children with GHD (age 4–12) in Germany, UK and USA. Interviews were analysed using ...
