Pro-Inflammatory (M1) and Anti-Inflammatory (M2) Profiles in Adipose Tissue of Lean and Obese Children and Adolescents

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Childhood obesity predisposes to metabolic disorders. Low grade inflammation of adipose tissue (AT) associated with macrophage infiltration may lead to metabolic complications. Two macrophage activation states M1 (pro-inflammatory) and M2 (anti-inflammatory) exist in AT with surface markers CD40 (M1), CD206 (M2) and CD163 (M2). M1 polarization correlates with metabolic complications.Objective and hypotheses: To study the expression of CD40, C...

Suppression of Bone Turnover and its Determinants in Children Receiving Bisphosphonate Therapy

Kyriakou Andreas , McNeilly Jane D , McMillan Martin , Shaikh Guftar M , Mason Avril , Ahmed Syed Faisal

Background: Bisphosphonate therapy (BPT) reduces osteoclast activity and may be associated with adynamic bone turnover. The extent of suppression of bone turnover and its determinants are unclear.Method: Markers of bone metabolism were evaluated in 15 children (9M/6F) undergoing BPT for osteoporosis. The median age at first biochemical assessment was 10.8 years (0.16, 16.3). Serum type I collagen cross-linked C-telopeptide (CTX), alkaline phosphatase (AL...

Novel Uncoupling Protein 1 Expression in White Adipocytes of Subcutaneous Abdominal Adipose Tissue in Children and Adolescents: A Protective Mechanism for Metabolic Equilibrium?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...

The Utility of AMH for Predicting Testosterone Response to hCG Stimulation in Children with Suspected DSD

Kyriakou Andreas , McNeilly Jane D , Shaikh Guftar M , Mason Avril , Shapiro David , Ahmed Syed Faisal

Background: In children undergoing investigation of testicular function the relationship between serum anti-Mullerian hormone (AMH) and the testosterone response to hCG stimulation test (HST) is unclear.Method: 75 children (3F, 72M) with a median age of 1.08 years (range, 0.003, 14.3) were investigated for suspected DSD by AMH on D1 and testosterone on D1 and D4, before and after 3-day HST. Of these children, 27 had an additional prolonged HST. Normal te...

Secondary Pseudohypoaldosteronism Type 1: the Role of a Urinary Steroid Profile

Grace M L , Murray D M , Joyce C , Taylor N F , Ghataore L , O'Connell S M

Background: Secondary pseudohypoaldosteronism (PHA) type 1 is an uncommon salt losing condition of infancy caused by transient resistance of the mineralocorticoid receptors (MR) of the renal tubule to aldosterone. This can be secondary to urinary tract infection (UTI), urinary tract malformation (UTM) or obstructive uropathy. Ninety percent of reported cases present before 3 months and nearly all are under 7 months of age.Objective and hypotheses: The co...

A Korean Boy with Pseudohypoparathyrodism Type Ia Presenting with Congenital Megacolon and Spinal Stenosis: Identification of a Novel GNAS Gene Mutation

Lee J E , Lee S H , Cho S Y , Ki C S , Jin D K

Pseudohypoparathyroidism (PHP) is a disease of rare frequency. There are five subtypes with each having different phenotypes and blood laboratory test results, which depend on gene mutation and hereditary styles. Among them, the most common type is PHP Ia which inherits maternal gene mutation and expresses Albright’s hereditary osteodystrophy (AHO) appearance, hypocalcemia, hyperphosphatemia and serum parathyroid hormone elevation. Another type, pseudo-pseudohypoparathyro...

Descriptive Analysis of Medication Adherence for Patients Treated with GH Therapy

Michels S L , Uribe C , Li Y , Meletiche D M , Velez F F , Locklear J C

Background: GH deficiency (GHD) occurs in one in 4000–one in 10 000 children, but can also be diagnosed in adults.1 GHD therapy typically requires injections over a period of years.2 Adherence to long-term GHT presents a challenge.Objective and hypotheses: This study describes the rates of adherence to GHT among patients with GHD.Method: Members who were continuously enrolled 6 months pre- and 12 months p...

Apoptosis Inhibitor of Macrophages: an Anti-Inflammatory Adipocyte Factor in Mild Adolescent Obesity?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papaxristou Dionysios , Miyazaki Toru , Spiliotis Bessie E

Background: Adipose tissue (AT) in obesity is characterized by low grade inflammation. The apoptosis inhibitor of macrophages (AIM; also called CD5L) is incorporated into adipocytes leading to increased lipolysis. Excess AIM-dependent lipolysis induces adipose tissue macrophage recruitment. M1 (proinflammatory) macrophage infiltration, with surface marker CD40, correlates with metabolic complications.Objective and hypotheses: To study serum levels and AT...

The Effect of Exenatide on Weight and Appetite in Overweight Adolescents and Young Adults with Prader–Willi Syndrome

Salehi Parisa , Hsu Isabel , Azen Colleen G , Mittelman Steven D , Geffner Mitchell E , Jeandron Debra

Background: Prader–Willi Syndrome (PWS) is a genetic disorder associated with hyperphagia and hyperghrelinemia with major morbidity due to obesity. The aetiology of hyperphagia is unknown, but presumed to be multifactorial, and, as ghrelin is orexigenic, high levels may contribute to weight issues in PWS. Currently, there is no effective medical treatment for hyperphagia in PWS, but targeting appetite could be beneficial. Exenatide (Byetta (synthetic exendin-4); AstraZene...

What is the natural history of cervicomedullary compression without signal change in infants with achondroplasia? Investigating foramen magnum stenosis evolution.

Harvey Charlotte , Brett Connor , Cocca Alessandra , D’Arco Felice , Irving Melita , Thompson Dominic , Cheung Moira ,

Background: Foramen magnum stenosis (FMS) is a common, serious complication of achondroplasia in infancy. The Achondroplasia Foramen Magnum Score (AFMS; 1-4) was developed to facilitate early detection of stenosis and inform appropriate neurosurgical management. All infants have a baseline screening MRI, of which approximately half of cases demonstrate AFMS3 (craniovertebral junction (CVJ) narrowing with flattening of the cervical cord) or AFMS4 (CVJ narrowing...
