Development and validation of simultaneous quantification of urinary catecholamines and free metanephrines by UHPLC-MS/MS method

Eugenia Rodriguez Maria , Gabriela Ballerini Maria , Ambao Veronica , Vieites Ana , Sanso Gabriela , Rey Rodolfo , Bergada Ignacio , Gabriela Ropelato Maria

Background: Neuroendocrine tumors from adrenal and extra-adrenal chromaffin cells are characterized by overproduction of catecholamines (CA), leading to the increase of urinary O-methylated metabolites (uO-Met) excretion, reliable biomarkers for the initial screening, diagnosis and monitoring of patients with pheochromocytoma and paragangliomas (PPGLs).Objective: To develop and validate a UHPLC-MS/MS method for the simul...

Serum IGFBP-2 Concentration in Neonates with Potential Diagnosis of Growth Hormone Deficiency (GHD)

Gabriela Ballerini Maria , Braslavsky Debora , Keselman Ana , Eugenia Rodriguez Maria , Gotta Gabriela , Gabriela Ropelato Maria , Bergada Ignacio

In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

Insulin Sensitivity in Girls with Central Precocious Puberty at Diagnosis and at 6 Months of GnRH Analogue Treatment

Arcari Andrea , Freire Analia , Escobar Maria Eugenia , Ballerini Maria Gabriela , Ropelato Maria Gabriela , Bergada Ignacio , Gryngarten Mirta

Background: Puberty is associated with a physiological decline in insulin sensitivity. Overweight and obesity are common among girls with Central Precocious Puberty (CPP). CPP and early menarche have been considered as risk factors for obesity and cardiovascular diseases during adulthood. Besides, concern has been raised by the potential impact of GnRH analogues (GnRH-a) treatment on body weight and metabolic profile.Objective and hypotheses: To evaluate...

Prolonged Treatment with Vitamin D Supplementation and High Dose is Necessary to Treat Vitamin D Deficiency/Insufficiency (VDD/I) in Children and Adolescents with Type 1 Diabetes

Xatzipsalti Maria , Dolianiti Maria , Papadopoulou Konstantina , Kouloufakou Penelope , Mitravela Vasiliki-Ioanna , Dracopoulou Maria , Stamogiannou Lela , Vazeou Andriani

Background: Increased frequency of VDD/I has been found in warmer countries over the last years.Objective and hypotheses: To evaluate the response to vitamin D treatment in VDD/I among children and adolescents with type 1 diabetes.Method: Total 25OHvitamin D levels (VDL) were measured in 76 consecutive children and adolescents with type 1 diabetes (36 males, mean age (S.D.) 13.6 (5.09) years, median disease duration ...

Changes in objectively measured physical activity after 2-year lifestyle intervention in pediatric patients with abdominal obesity

Ojeda-Rodriguez Ana , Morell-Azanza Lydia , Luis Leon Jose , Macias Maria , Chueca Maria , Marti Amelia , Cristina Azcona-Sanjulian Maria ,

Introduction: it has been widely demonstrated that high physical activity (PA) levels prevent obesity development. The practice of moderate, regular PA reduces abdominal obesity, hypertension, insulin resistance, dyslipidemia and improves risk factors for obesity-related comorbidities (e.g. diabetes or cardiovascular diseases) independently of weight loss. However, in the childhood population, where sedentary behavior has increased in recent decades, few studi...

Sleep quality and metabolic syndrome in pediatric patients with abdominal obesity

Catalan Ana , Ana Ojeda-Rodriguez , Gea Alfredo , Macias Maria , Chueca Maria , Berrade Sara , Marti Amelia , Azcona-Sanjulian Maria Cristina ,

Aim: to evaluate sleep quality by accelerometry and its association with anthropometry and biochemical parameters in children and adolescents after a multidisciplinary interventionSubjects Materials and Methods: One hundred and twenty-two children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a multidisciplinary intervention study to lose weight. Abdominal obesity was diagnosed using the waist circumference...

Outcomes of treatment in pediatric Cushing`s disease

Yanar Eda , Makazan Nadezhda , Kareva Maria

Objective: The first line of treatment for Cushing&grave;s disease (CD) is transsphenoidal surgery (TSS), whose effectiveness range is from 70 to 90%. If surgical treatment is unsuccessful or recurrence appears, radiation treatment (RT) is the next therapeutic option, which effectiveness range is also 90%, but the hypopituitarism rate as side effect of treatment is higher.Aim: Analysis of recurrence rates of CD and side ...

SARS-CoV-2 pandemic and GH treatment: new strategies to abate the distance

Corsello Giovanni , Campa Luigi , Cristina Maggio Maria

SARS-CoV- 2 pandemic induced to develop new strategies to abate the distance between patients, families and paediatricians, especially in cases of patients who need long-term therapies. Furthermore, the need to minimize the inflow of children and adolescents affected by chronic diseases into the hospitals induced paediatric endocrinologists to limit visits and to consider a new setting to assist children in treatment with growth hormone (GH). Telemedicine and smart-working cou...

Use of PDE5 inhibitors as a potential treatment for isolated growth hormone deficiency caused by alternate splicing of GH1 gene.

Pandey Amit , Natalia Rojas Velazquez Maria

Mutations in the GH1 gene cause isolated growth hormone deficiency (IGHD) by affecting production, secretion, and stability of growth hormone as well as its binding to GHR. A smaller isoform of GH1 is inactive and is linked to IGHD. While studying the impact of small GH isoform, we noticed that cells with the short 17.5 kD version of GH looked different from the control cells. We found that the production of short GH isoform distorts the cell morphology, contributing to detrim...

Hypothalamic AgRP Neurons Drive Endurance in Food-restricted Mice

Miletta Maria Consolata , Horvath Tamas L.

Diseases of food restriction, such as anorexia and bulimia nervosa, are psychiatric conditions with the highest mortality. It is not known how these disorders emerge and what determine mortality. Individuals with these disorders frequently engage in compulsive exercise. States of food restriction are associated with elevated activity of hypothalamic neurons that produce AgRP, which cells are crucial for feeding and can promote stereotypic behaviors.Here,...
