A Monomeric Peptide Triagonist for the Treatment of Obesity and Diabetes

Clemmensen Christoffer , Finan Brian , Muller Timo , DiMarchi Richard , Tschop Matthias

Encouraged by unimolecular dual incretin co-agonists (GLP1/GIP) to enhance glycemic efficacy (Finan et al. 2013, Sci Transl Med) and GLP1/glucagon co-agonists to enhance weight loss efficacy (Day et al. 2009, Nat Chem Biol) and to restore diet-induced leptin sensitivity (Clemmensen et al. 2014, Diabetes), we recently developed the first tri-agonist (GLP1/GIP/glucagon) for the treatment of metabolic disorders (Finan et al. 2014, Nat Med). Importantly, this concerted triple agon...

Ethnic Variation in the Correlation of Waist Circumference to Daily Insulin Requirement in Children with Type 1 Diabetes

Uday Suma , Gorman Shaun , Feltbower Richard , Mathai Mathew

Introduction: Daily insulin requirement in type 1 diabetes (T1D) depends on various factors.Objectives: To study the correlation of waist circumference (WC) and BMI to daily insulin requirements (TDD) and examine the ethnic variation in this correlation. Associations of estimated glucose disposal rate (eGDR) a surrogate marker of insulin resistance were also studied.Methods: Cross-sectional study of children with T1D attending a di...

Effects of Exposure to the Endocrine disruptor di(n-butyl) Phthalate on Testicular Dysgenesis Fetal Germ Cell Development in the Rat and in Human Fetal Testis

Mitchell Rod , van den Driesche Sander , Hrabalkova Lenka , Anderson Richard , McKinnell Chris , MacPherson Sheila , Calarrao Ana , Sharpe Richard

Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...

Increased Islet Cell Neogenesis and Endocrine Cell Differentiation in Congenital Hyperinsulinism in Infancy

Hardwick Elise , Han Bing , Salomon-Estebanez Maria , Padidela Raja , Skae Mars , Craigie Ross , Cosgrove Karen , Banerjee Indi , Dunne Mark

Background: Congenital Hyperinsulinism in Infancy (CHI) is characterised by inappropriate insulin release. We currently attribute hypoglycaemia to β-cell dysfunction because of defects in the ion channel genes ABCC8 or KCNJ11. However, the CHI pancreas is also associated with inappropriate expression of foetal-like transcription factors and enhanced cell proliferation.Hypothesis: As the CHI pancreas bears similarities to the foetal pancreas, we hypo...

Islet of Langerhans in Congenital Hyperinsulinism in Infancy are Disrupted and with Decreased Expression of Collagen (IV) α1 Chain in Basement Membranes

Mal Walaa , Salomon-Estebanez Maria , Padidela Raja , Skae Mars , Craigie Ross , Rigby Lindsey , Cosgrove Karen , Banerjee Indi , Dunne Mark

Background: Congenital hyperinsulinism of infancy (CHI) is the most common cause of severe hypoglycaemia in children. Although CHI arises from mutations in KATP channels which lead to inappropriate insulin secretion, CHI it also is associated with marked changes in islet organization.Aims and objectives: Our aim was to investigate the structure and composition of the islet capsule in CHI and age-matched control tissue.Me...

Height Gain and Safety Outcomes in Growth Hormone (GH)-Treated Girls and Boys with Idiopathic Short Stature (ISS): Experience from the Prospective GeNeSIS Observational Study

Child Christopher , Quigley Charmian , Zimmermann Alan , Deal Cheri , Ross Judith , Rosenfeld Ron , Cutler Jr Gordon , Blum Werner

Background: GH treatment for ISS received first approval in the USA in 2003 based on data from two controlled clinical trials. Eligibility is restricted to those with baseline (BL) height standard deviation score (HtSDS) ≤−2.25; other approvals followed, but not in Europe.Objective and hypotheses: To assess outcomes of GH therapy in a large cohort of patients (pts) treated in routine clinical practice.Methods: Short-ter...

Islet δ-Cells Contribute to the Pathobiology of Atypical Congenital Hyperinsulinism

Han Bing , Bourke Siobahn , Mohammad Zainab , Craigie Ross , Skae Mars , Cheeseman Edmund , Banerjee Indi , Cosgrove Karen , Dunne Mark

Background: Atypical forms of congenital hyperinsulinism in infancy (CHI-A) represent a novel subgroup of patients who present later in the neonatal period; have poor responses to medical intervention; an unremarkable histopathology and no known genetic cause of disease.Objective and hypotheses: To compare the expression profiles of insulin and somatostatin in islets from patients with CHI-A, diffuse CHI (CHI-D) and age-matched control tissue.<p clas...

Failure to Terminate Cell Proliferation Contributes to the Pathobiology of Congenital Hyperinsulinism in Infancy

Han Bing , Mohammad Zainab , Rigby Lindsey , Craigie Ross , Skae Mars , Padidela Raja , Cheesman Edmund , Cosgrove Karen , Banerjee Indi , Dunne Mark

Background: Diffuse congenital hyperinsulinism in infancy (CHI-D) mainly arises from mutations in KATP channel genes. In addition, there are also several reports of increased cell proliferation in CHI-D. We hypothesised that the higher rates of proliferation in CHI-D are as a consequence of failure to terminate proliferation in the neonatal period.Objective and hypotheses: To test this we examined the proliferative index (PI) of CHI-D tissue a...

Congenital Hyperinsulinism in Infancy: The Profiles of Insulin Secretory Granules are Markedly Different in Focal- and Diffuse β-Cells

Han Bing , Mohamed Zainab , Salomon-Estebanez Maria , Padidela Raja , Skae Mars , Craigie Ross , Rigby Lindsey , Cosgrove Karen , Banerjee Indi , Dunne Mark

Background: The mechanisms responsible for inappropriate insulin release from β-cells in congenital hyperinsulinism in infancy (CHI) have largely focused upon defects in KATP channels. Little is known about insulin biogenesis, the profiles of insulin in insulin-containing secretory granules or whether the impact of KATP channel defects is the same in diffuse- and focal disease.Objective and hypotheses: To define the ultrastruct...

Evolution of Feminising Genitoplasty

Pippi-Salle J L

Great controversy exists in regard to the timing and technical alternatives to perform feminizing genitoplasty in children. Opponents to an early approach argue that the reconstruction can be risky in terms of clitoral/vaginal function therefore surgery should be postponed until the patient herself can sign an informed consent and be aware of potential risks as well as confirms the desire to undergo the procedures. Such negative feelings in regard to early reconstruction are b...
