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...

Background: Heterozygous GHR gene variants were found in 5–8% of idiopathic short stature (ISS) children. Frequent polymorphisms within GHR coding regions, but not intronic SNPs, have been investigated in ISS.Objectives: To characterize GHR gene variants in ISS children, and to test their influence on height and the peripheral GH/IGF1/IGFBPs system.Methods: GHR gene (coding/intronic flanking...

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...

Gutierrez Marcela , Soria Marcela , Morán Lorena , Ferraro Cristina , Bedecarrás Patricia , Drelichman Guillermo , Aversa Luis , Bergadá Ignacio , A. Rey Rodolfo , P. Grinspon Romina

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

Background: Several genetic defects (GHR, SHOX, GHSR, NPR2, IGFALS) have been reported in children classified as ISS. ISS children are GH sufficient and about one third of them show low IGF-I levels, suggesting some degree of GH insensitivity.Objective: To explore potential genetic defects in ISS children suspicious of GH insensitivity, selected by low IGF-I levels and low response to IGF generation test.<...
