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...

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...

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...

Background: The new preventive child health care guideline for referral of short/tall children facilitates early detection of growth disorders. Understanding the impact of early treatment initiation on recombinant human growth hormone (rhGH) adherence and catch-up growth can support the use of the guideline.Aim: To evaluate the impact of age at rhGH treatment start on adherence (≥85% vs <85% of prescribed doses...

Aggrecan is a structural glycoprotein of the extracellular matrix of cartilage present in the articular cartilage, growth plate and cartilage of the intervertebral disc. Biallelic pathogenic variants are the cause of aggrecan type spondyloepiphyseal dysplasia (OMIM#612813) while the presence of heterozygous pathogenic variants determine Kimberley type spondyloepiphyseal dysplasia (OMIM#608361) and short stature associated or not with acceleration of bone maturation and early o...

Introduction: Exosomes are extracellular vesicles whose cargo includes proteins that may influence the function of distant cells. It is unknown, however, whether there are differentially expressed proteins (DEPs) in the circulating exosomes of appropriate- vs small-for-gestational-age (AGA vs SGA) infants at birth and, if so, whether such DEPs relate to measures of endocrine-metabolic health and body composition in childhood.Subj...

Background: The Growzen™ Buddy app was developed to improve adherence to recombinant human growth hormone (r-hGH) therapy among patients with growth disorders. This app sends alerts for injection timings and allows patients and their caregivers to self-monitor growth, develop a treatment routine, improve adherence, and ultimately take ownership of treatment outcomes. The app also contains a library of educational resources designed to empower patients to...

Introduction: Type 1 diabetes (T1D) is due to decreased insulin production due to autoimmune destruction of β cells. There is an increase in the diagnosis of T1D in young patients with poor pancreatic reserve due to greater destruction of β cells and more complex evolution.Objectives: To classify patients into different Endotypes based on age, characteristics at onset, and progression one year later.<p clas...

Disorders of sexual development can be suspected from birth if there is genital ambiguity, but sometimes the diagnosis in girls is made at puberty due to lack of pubertal development or primary amenorrhea. Making the correct diagnosis has its relevance in sexual identity, in the initiation of the correct hormone replacement therapy and in its possible association with malignant gonadal tumors. We describe 2 cases with unusual presentation of girls with female phenotype and 46X...
