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...

Long-Term Effect of Gonadotropin-Releasing Hormone Analogue Therapy on Adult Height in Girls with Central Precocious Puberty Diagnosed before 4 Years of Age

Freire Analía , Gryngarten Mirta , Gabriela Ballerini María , Vieites Ana , Gabriela Ropelato María , Arcari Andrea

Background: Central precocious puberty (CPP) is uncommon before the age of 4 and treatment with GnRH analogues have shown unequivocal benefits. CPP during or near mini puberty entails differential clinical and biochemical features in the diagnosis and leads to longer treatment and follow-up. There are very limited studies with long-term outcomes about CPP girls exclusively < 4 years of age regarding growth, menarche, and adult height after GnRHa withdrawal....

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 ...

Presentation and outcome of ATA-Pediatric low-risk differentiated thyroid carcinoma (PLR-DTC) with high-invasive molecular alterations

Papendieck Patricia , Eugenia Masnat Maria , Boycho Marisa , Colli Sandra , Victoria Preciado Maria , Lorenzetti Mario , Arcari Andrea , Chiesa Ana

PLR-DTC patients defined as having a tumor grossly confined to the thyroid with minimal or no central lymph nodes comprises 40% of all pediatric DTC followed-up in our center. High-invasive molecular alterations (HIMA) have been reported recently in around 57% of these patients with a still not clear explanation on their influence in outcome.Objective: To report the characterization of a small group of PLR-DTC patients who were positive ...

Prevalence of Polycystic Ovarian Syndrome (PCOS) In Girls with History of Idiopathic Central Precocious Puberty (ICPP).

Josefina Arcari Andrea , Verónica Freire Analía , Gabriela Ballerini María , María Díaz Marsiglia Yenifer , Bergadá Ignacio , Gabriela Ropelato María , Graciela Gryngarten Mirta

Introduction: The prevalence of PCOS in adolescents and young women was established at 4.3%. Whether women with a history of ICPP are at increased risk for PCOS is still controversial. There is no clear evidence that ICPP girls treated with GnRH analogues (GnRHa) are more likely to develop PCOS than their age-matched peers.Objectives: To assess the prevalence of PCOS in adolescents with a history of ICPP and further comp...

GnRH Infusion in Females with Hypogonadotropic Hypogonadism

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...

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...
