Circulating MKRN3 levels in 5 CPP girls with MKRN3 gene mutation

Aiello Francesca , Palumbo Stefania , Cirillo Grazia , Luongo Caterina , Festa Adalgisa , Miraglia Del Giudice Emanuele , Grandone Anna

Background: MKNR3 is a paternally expressed gene whose loss-of-function mutations cause Central precocious puberty (CPP). The precise molecular disruption produced by MKRN3 mutations remains unclear albeit protein structure suggests MKRN3 could play a role in proteasome ubiquitination. Circulating MKRN3 levels has been negatively associated to LH peak, estradiol and kisspeptin in idiopathic CPP and healthy controls. However, no literature data is available for...

Association Between Adiposity Measures and Metabolic Variables in Children and Adolescentswith Obesity

Umano Giuseppina Rosaria , Di Sessa Anna , Cirillo Grazia , Ursi Davide , Marzuillo Pierluigi , Miraglia Del Giudice Emanuele

Childhood obesity has become a major health issue in the last decades. Moreover, identifying a simple, feasible, and valid screening tool to select subjects at higher risk for obesity-related comorbidities has become a challenge. Current guidelines reccommend to use BMI percentile for overweight and obesity diagnosis. However, waist-to-height ratio (WHR) has been associated with the risk of metabolic derangement in children and adolescents with overweight and obesity. In addit...

Early Menarche is Associated with Insulin Resistance and Non-Alcoholic Fatty Liver Disease in Obese Adolescents

Di Sessa Anna , Grandone Anna , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Background: Menarche is a significant event in the reproductive life of a woman and represents the late event in puberty indicating that a sexually immature child has become reproductively capable. Even though the timing of puberty onset is approximately conserved in different populations, the puberty starts across a wide range of ages in normal girls. However, in the last decades we are observing that girls are experiencing earlier breast development and earlier menarche, als...

Predictors of kidney damage development in children with metabolically healthy and metabolically unhealthy obese phenotypes

Di Sessa Anna , Paride Passaro Antonio , Maria Colasante Alberto , Ferrara Serena , Rosaria Umano Giuseppina , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Background: A close association has been reported between obesity and renal damage in adults, but evidence in childhood is still limited.Methods: We retrospectively studied 396 children and adolescents with obesity. Clinical, biochemical, and instrumental evaluations were performed. Patients were stratified according to the metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) phenotypes. Kidney d...

Obstructive sleep apnea (OSA) is associated with the impairment of beta-cell response to glucose in children and adolescents with obesity

Rosaria Umano Giuseppina , Galderisi Alfonso , Aiello Francesca , Martino Mariangela , Di Sessa Anna , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Purpose: The main purpose of the study is to assess the association between obstructive sleep apnea (OSA) and insulin secretion in children with obesity.Objectives: To achieve our aim we have assessed OSA and measured insulin secretion by the using the oral minimal model (OMM) in a cohort of 77 obese children and adolescents.Methods: We retrospectively enrolled children and adolesc...

“Cushing’s syndrome in a girl with Carney Complex: a case report”

Rivetti Giulio , Caterina Luongo , Aiello Francesca , Miraglia Del Giudice Emanuele , Marzuillo Pierluigi , Di Iorio Giovanni , Pellino Valeria , Grandone Anna

Background: Carney complex (CNC) is a rare autosomal dominant multiple endocrine neoplasia and lentiginosis syndrome, characterized by abnormal cutaneous and mucosal pigmentation, myxomas of the heart, skin, breast and other non-endocrine tumors. CNC is principally caused by loss-of-function mutations of PRKAR1A gene located at 17q22-24 coding for the regulatory subunit type I alpha of protein kinase A (PKA) gene. Cushing’s syndrome is a rare disorder in...

The rs72613567:TA Variant in the Hydroxysteroid 17-beta Dehydrogenase 13 Gene Reduces Liver Damage in Obese Children

Sessa Anna Di , Rosaria Giuseppina , Cirillo Grazia , Marzuillo Pierluigi , Arienzo Maria Rosaria , Pedulla' Marcella , Miraglia Del Giudice Emanuele

Background: The rs72613567:TA variant in the hydroxysteroid 17-beta dehydrogenase 13 (HSD17B13) gene has been associated with decreased risk of liver damage.Aims: To investigate the association between the HSD17B13 rs72613567:TA variant and both hepatic steatosis and biochemical markers of liver damage in obese children and to evaluate its potential effect in NAFLD genetic predisposition.<p...

The influence of Non-Alcoholic Fatty Liver Disease and of its genetics on thyroid function in children with obesity

Di Sessa Anna , Cembalo Sambiase Sanseverino Nicoletta , Maddalena Marrapodi Maria , Rosaria Umano Giuseppina , Cirillo Grazia , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Background: The patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M and the transmembrane 6 superfamily member 2 (TM6SF2) E167K polymorphisms have been recognized as the major risk polymorphisms for Non-Alcoholic Fatty Liver Disease (NAFLD). Data supported a close relationship of NAFLD with thyroid function both in adults and children. To investigate the influence of NAFLD and of its genetics on thyroid function.<p class...

The lncOb rs10487505 polymorphism impairs insulin sensitivity and glucose tolerance in children and adolescents with obesity

Rosaria Umano Giuseppina , Cirillo Grazia , Rondinelli Giulia , Vittoria Foderini Maria , Ferrara Serena , Di Sessa Anna , Marzuillo Pierluigi , Santoro Nicola , Miraglia del Giudice Emanuele

Purpose: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long-noncoding RNA, also referred as lncOb, has been described in mice. In humans, a correspondent polymorphism (rs10487505) has been associated with relatively low plasmatic leptin levels compared to obesity severity and with early obesity onset.Objectives...

Background: Silver Russell Syndrome (SRS) is characterized by pre- and postnatal growth failure, relative macrocephaly at birth, prominent forehead, feeding difficulties and body asymmetry. The diagnosis is clinical, the genetic mechanisms involved are different, in 50% of cases loss of methylation (LOM) at the paternal H19/IGF2:IG-DMR (chr11p15.5), in 10% of cases maternal uniparental disomy of chromosome 7 (UPD(7)mat), cases of maternal uniparental ...
