Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: To investigate the frequency of IGF1R mutations in a cohort of patients with pre- and/or postn...

Diamantino Catarina , Caetano Francisco , Luísa Leite Ana , Costa Carla , Vieira Paula , Novais Sandrina , Borges Teresa , Pereira Carla

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...

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...

Analysis of Correlation between Stem Cells (CD133+/CD45+ and CD133+/CD45) and Anthropometric Parameters of Children with Growth Hormone/Primary Insulin-Like Growth Factor 1 Deficiency

Sawicka Beata , Moniuszko Marcin , Grubczak Kamil , Singh Paulina , Radzikowska Urszula , Mikłasz Paula , Dębrowska Milena , Bossowski Artur

Introduction: Hematopoetic progenitor stem cells (HSCs, CD133+/CD45+) and very small embryonic-like stem cells (VSELs, CD133+/CD45−) can differentiate into specific immune cells. Some studies suggest that levels of HSCs and VSELs change during therapy with growth hormone (GH) or insulin-like growth factor 1 (IGF-1). GH deficiency (GHD), an endocrine disease connected with insufficient production of GH by pituitary gland, is tre...

ALS Deficiency due to a Novel and Two Already Described IGFALS Gene Mutations in an Unusual Non Consanguineous Family: Two Compound Heterozygous (Father and Son) and Two Heterozygous Carriers (Brother and Mother)

Scaglia Paula , Keselman Ana , Martucci Lucia , Karabatas Liliana , Ballerini Maria Gabriela , Domene Sabina , Johanna Acosta , Jasper Hector , Domene Horacio

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...

Background: Kallmann syndrome (KS) is a rare clinical entity, characterized by the association of hipogonadotropic hypogonadism and hypo/anosmia, with an estimated prevalence of 1:8000 in males and 1:40 000 in females.Method: Retrospective study of cases of KS diagnosed in paediatric age. Genetic analysis was performed by PCR and DNA sequencing of KAL1, FGFR1, GNRHR, GNRH1, PROK2, PROKR2, KISS1R, TAC3, TACR3, and FGF8 genes.Results...
