Obesity Caused by Mutations in the Melanocortin 4 Pathway: Experience From a Teaching Hospital

Gupta Sanjay , Dalpathadu Sanjalee , Mathew Verghese , Greetham Sandra

Introduction: The role of genetics in obesity is a much under discussed area. Whilst it is undeniable that environmental factors play a major role in obesity in most cases, there is a small proportion of cases where genetic mutations are the main underlying cause. This includes novel monogenic conditions involving mutations in the Melanocortin-4 receptor (MC4R) signalling pathway. In a healthy individual, the post-meal increase in leptin (LEP) stimulates melan...

Modified Insulin Stress Test for Assessment of Growth Hormone Secretion – Experience from a University Teaching Hospital

Gupta Sanjay , Dean Olivia , Mathew Verghese , Tharian Kavitha , Willingham Linda

Introduction: Insulin stress test (IST) to diagnose growth hormone (GH) deficiency is rarely used by paediatric endocrine teams in the United Kingdom, due to concerns over safety. We share our experience of undertaking modified IST in children, with regards to safety and outcomes.Methods: We adapted the protocol for insulin stress test, proposed by Galloway et al to undertake pituitary stimulation test for our c...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

Noonan Syndrome (NS) Spectrum Panels should Include Mutations in LZTR1 Gene

Güemes Maria , Martín-Rivada Álvaro , Ortiz-Cabrera Nelmar Valentina , Martos-Moreno Gabriel Ángel , Pozo-Román Jesús , Argente Jesús

Background: A few patients with NS have been reported to harbour pathogenic mutations in LZTR1 gene. RAS regulation by LZTR1-mediated ubiquitination provides an explanation for the role of LZTR1 in human disease. Mutations in this gene could hence lead to NS phenotype. Three patients with mutations in this gene and compatible NS phenotype are herein described.Case 1: A 5 year-old boy with bilateral cryp...

Introduction: Short stature is a multifactorial condition caused by both genetic and environmental factors. Genetic causes include chromosomal disorders and diseases inherited by monogenic and multifactorial inheritance. The purpose of genetic evaluation in short stature is not only for diagnosis, but also to provide additional information to the patients and their families about prognosis of the disease, treatment approaches and genetic counseling.<p clas...

Glutamic acid decarboxylase (GAD) is the enzyme that catalyzes the conversion of L-glutamat into GABA, one of the classical neurotransmitters with neuroinhibitory function. GAD is present in GABAergic neurons and in pancreatic beta cells. It is remarkable that Anti-GAD antibody(Anti-GADab) can have different disease manifestations, i.e., Type 1 diabetes mellitus (T1DM), Stiff-Person Syndrome, limbic encephalitis (LE), epilepsy. Cooccurence of T1DM and LE is reported in the lit...

Evaluation of Fetuin-A Level and Related Factors in Obese Adolescents

Karacan Kücukali Gülin , Çetinkaya Semra , Kurnaz Erdal , Bayramoglu Elvan , Özalkak Servan , Demirci Gulsah , Serdar Öztürk Hasan , Savas Erdeve Senay , Aycan Zehra

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Three Cases with Familial Short Stature: Leri-Weill Syndrome

Ayranci Ilkay , Çatli Gönül , Eroğlu Filibeli Berna , Manyas Hayrullah , Bekir Kutbay Yaşar , Koç Altuğ , Nuri Dündar Bumin

Introduction Objective: The SHOX gene is located in pseudoautosomal region of chromosomes of Xp22.33 and Yp11.32. It plays role in proliferation and differentiation of epiphyseal chondrocyte. Leri-Weill syndrome is observed with loss of an allele, while missense mutations lead to idiopathic short stature without any dysmorphic findings. This report presents clinical features of three cases diagnosed with Leri-Weill syndrome, and their responses to rhGH treatme...

Evaluation of the Role of Fetuin A in Pathophysiology of Polycystic Ovarian Syndrome in Adolescents

Bayramoğlu Elvan , Çetinkaya Semra , Özalkak Şervan , Kurnaz Erdal , Demirci Gülşah , Serdar Öztürk Hasan , Savaş Erdeve Şenay , Aycan Zehra

Introduction: Policystic ovarian syndrome (PCOS); is an endocrinopathy characterised by overlap of hyperandrogenism and hyperinsulinism and chronic anovulation. Etiopathogenesis is still not clearly defined. Fetuin-A is aserum glycoprotein. It is shown to play regulatory functions in many inflammatory processes. We aim to define the relationship of fetuin-A levels with hyperandrogenism and hyperinsulinism in PCOS patients and study the role in pathophysiology....
