Due to the increase in prevalence of childhood obesity, more obese children are referred to the endocrinologist for the hypothalamus-hypophysis-adrenal axis assessment. The circadian rhythm (CR) of cortisol in saliva (SAF) may constitute a non-invasive, first line test to exclude hypercortisolism on obese children.Aim: To evaluate possible disturbances of CR of SAF in obese children with clinical signs of hypercortisolism.<p class="a...

The survival rate of young patients with cancer has greatly improved in the last decades, in part due to the introduction of new therapeutic agents and protocols.Chemotherapy may be associated with risk of ovarian dysfunction, permanent or transient amenorrhea, symptoms of ovarian insufficiency and infertility.It has been suggested that prepubertal ovary is less susceptible to deleterious effect of chemotherapy.<p class="abstex...

Gonadotropin Flare with Different Depot GnRH Agonists: Comparative Analysis.

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

Central precocious puberty (CPP) is effectively treated by inhibition of GnRH signaling through GnRH receptor desensitization with depot GnRH agonists (dGnRHa), but the first injection is associated with a surge in LH and FSH (flare) that proportionally increases estradiol levels. When estradiol levels drop, usually within a fortnight, vaginal bleeding may be seen in a small number of girls. Although dGnRHa that use higher, longer-acting doses are increasingly being used in gi...

Adiponectin as a Marker of Peripheral Insulin Resistance in Adolescents with Polycystic Ovarian Syndrome (PCOS) and as a Tool to Suspect Insulin Receptor Defects

Freire Analia , Gryngarten Mirta , Ballerini Maria Gabriela , Arcari Andrea , Bengolea Sonia Viviana , Scaglia Paula , Bergada Ignacio , Ropelato Maria Gabriela

Background: Decreased serum adiponectin levels are associated with obesity and peripheral insulin resistance (IR). PCOS is characterized by hyperandrogenism and chronic anovulation and frequently is associated to IR. Some defects of Insulin Receptor have been proposed as mechanisms to explain ovarian hyperandrogenism in PCOS.Objectives: To explore adiponectin levels in adolescents with PCOS and to evaluate if adiponectin would identify potential patients...

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...

Polycystic Ovarian Syndrome in Adolescents: Metabolic Profile at Diagnosis, During and After Treatment with Oral Contraceptive

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

Background: Obesity and unfavorable metabolic profile (insulin resistance and/or dyslipidemia) are frequently observed in Polycystic Ovarian Syndrome in Adolescents (PCOS) girls regardless of weight.Objective and hypotheses: To evaluate clinical features and metabolic profile in PCOS adolescents, before, during and after Oral Contraceptive (OC) treatment.Method: We performed a retrospective study on 51 girls with PCOS diagnosed acc...

Optimal Strategy for Ovarian Function Assessment in Girls with Central Precocious Puberty before and During GnRH Analogue Treatment

Freire Analia , Gryngarten Mirta , Arcari Andrea , Ballerini Maria , Loreti Nazareth , Ambao Veronica , Bergada Ignacio , Campo Stella , Ropelato Maria

Background: The degree of suppression of the pituitary-ovarian axis in girls with central precocious puberty (CPP) under GnRH analogue (GnRHa) treatment is usually assessed at pituitary levels. However, the extent of ovarian function suppression under GnRHa treatment has not been evaluated.Objective: To evaluate ovarian activity in CPP girls before and during treatment with GnRHa.Patients and methods: In this prospective study, 11 ...

GnRH Infusion in Females with Hypogonadotropic Hypogonadism

Freire Analia , Arcari Andrea , Grinspon Romina , Ballerini Maria Gabriela , Sanguineti Nora , Bergada Ignacio , Escobar Maria Eugenia , Ropelato Maria Gabriela , Gryngarten Mirta

Background: Hypogonadotropic hypogonadism (HH) in females is an uncommon and heterogeneous condition. There is little data regarding biochemical profile of gonadotropins to further substantiate the diagnosis.Objective: To evaluate the gonadotropaic secretion profile after GnRH infusion in a female cohort diagnosed with HH.Patients and methods: GnRH iv infusion test (0–120 min) were performed in 17 patients (17.5±2.3 years...

Ovarian AMH production is transiently affected in pubertal and prepubertal girls with acute lymphoblastic leukaemia and non-Hodgkin lymphoma receiving chemotherapy: a prospective, longitudinal study.

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Cystic Fibrosis-related diabetes

Kelly Andrea ,

Emerging in childhood and becoming increasingly prevalent to affect 40-50% of adults with cystic fibrosis (CF), CF-related diabetes (CFRD) is a common co-morbidity with the potential to negatively impact nutritional status, pulmonary function, and survival. Stymying interventions to preserve beta-cell function, the mechanisms underlying the progressive insulin secretion defects responsible for CFRD are poorly delineated. This meet-the-professor session will use case-based pres...
