Pancreas Unfolded Protein Response is activated in Intrauterine Growth Restriction

Deodati Annalisa , Fausti Francesca , Pampanini Valentina , Cianfarani Stefano

Background: Intrauterine growth restriction (IUGR) is associated with higher risk of cardiometabolic disease. Perturbation of endoplasmic reticulum (ER) homeostasis activates a set of ER-to-nucleus signaling pathways known as unfolded protein response (UPR). We previously showed that IUGR is associated with the activation of hepatic UPR and abnormal glucose profile in male Sprague-Dawley rats. Herein, we report the impact of IUGR on pancreas UPR in the same ex...

Long-term safety of rhGH therapy in childhood has been object of intense investigation in the last decade. Two recent observational studies have focused on the risk of cardiovascular diseases in young adults treated with rhGH during childhood. After subdividing the large cohorts of patients in different risk groups they found that both mortality and morbidity from cardiovascular diseases were higher than the general population in the low risk group including patients with isol...

Effect of Intrauterine Growth Restriction on Ovarian Follicle Pool

Pampanini Valentina , Germani Daniela , Puglianiello Antonella , Jahnukainen Kirsi , Sahlin Lena , Cianfarani Stefano , Soder Olle

Introduction: A low oxygen and/or nutrient supply to the fetus, resulting in intrauterine growth restriction (IUGR), can affect gonadal development of the offspring and have a potential impact on fertility. Epidemiological studies on subjects born small for gestational age (SGA), as a surrogate measure of IUGR, have reported contradictory results. Data derived from animal models of placental insufficiency are limited.Objective and hypotheses: To investig...

Expression of Type 1 Insulin-like Growth Factor Receptor (IGF-1R) in Liver of Obese Children with Non-alcoholic Fatty Liver Disease (NAFLD)

Pampanini Valentina , De Stefanis Cristiano , Alisi Anna , Inzaghi Elena , Nobili Valerio , Cianfarani Stefano

Background: Type 1 insulin-like growth factor receptor (IGF-1R) is the product of a single-copy gene located on chromosome 15 and is ubiquitously expressed in humans. Increased hepatic IGF-1R gene expression is found in hepatocellular carcinoma and in chronic hepatitis C, making parenchymal and non-parenchymal cells more susceptible to the mitogenic effects of IGF-1.Objective and hypotheses: As we have previously demonstrated that IGF-1 and IGF-2 circula...

Fetuin A Serum Levels in Children with Nonalcoholic Fatty Liver Disease

Pampanini Valentina , Inzaghi Elena , Nobili Valerio , Germani Daniela , Puglianiello Antonella , Cianfarani Stefano

Background: Fetuin A is a hepatokine known as a natural inhibitor of the insulin receptor tyrosine kinase and is associated with insulin resistance and nonalcoholic fatty liver disease (NAFLD). Studies on adults provided conflicting results regarding the link between fetuin A and the severity of liver damage in NAFLD. Data on children are limited.Objective: To investigate the relationship between fetuin A, metabolic parameters, and NAFLD in obese childre...

IGF1 is Associated with a More Favourable Pattern of Body Composition in Obese Children

Inzaghi Elena , Pampanini Valentina , Alessio Paola , Fiori Rossana , Ferroli Barbara Baldini , Cianfarani Stefano

Background: Recent studies have suggested a role of IGF1 as a candidate prognostic marker for cardiometabolic complications of obesity.Objective: To investigate the relationship between IGF1 serum levels and both biochemical and metabolic parameters as well as body composition in a cohort of obese children.Methods: obese subjects (130F/157M), aged 11.2±2.7 years, were studied. Anthropometry, biochemical and metabolic parameter...

Increased incidence of childhood type 1 diabetes during COVID-19 pandemic. Figures from an Italian tertiary care center

Deodati Annalisa , Rapini Novella , Pampanini Valentina , Ciampalini Paolo , Cristina Matteoli Maria , Patriza Patera Ippolita , Schiaffini Riccardo , Stefano Cianfarani

Background: CDC (Centers for Disease Control and Prevention) reported an increased risk of newly diagnosed diabetes over 30 days after SARS-CoV-2 infection among persons aged < 18 years. Similarly, the results from the DPV Registry demonstrated a significant increase in the incidence of pediatric Type 1 Diabetes during COVID-19 pandemic. The underlying mechanisms are not yet elucidated.Aim: To investigate the incidenc...

Intrauterine Growth Restriction Affects Postnatal Testis Maturation in Rats

Pampanini Valentina , Germani Daniela , Puglianiello Antonella , Stukenborg Jan-Bernd , Reda Ahmed , Savchuk Iuliia , Kjartansdottir Ros , Cianfarani Stefano , Soder Olle

Background: The influence of intrauterine life on long term health is supported by a wealth of epidemiological and experimental studies. A low oxygen and/or nutrient supply to the fetus, resulting in intrauterine growth restriction (IUGR), may affect gonadal development of the offspring, with a potential impact on fertility. Data derived from animal models of placental insufficiency are very limited.Objective and hypotheses: To investigate the effects of...

Background: In Italy monogenic forms of hyperglycemia account for more than 6% of cases referred to pediatric diabetes clinics. In January 2019 we started a Monogenic Diabetes Clinic (MDC) with the three main aims: a) implementing a standardized pathway towards genetic testing, 2) ease the revision of complex cases, 3) implement standardized therapies for monogenic diabetes mellitus (MDM) subtypes.Methods: Type 1 diabete...

Could Brain MRI Replace GH Stimulation Tests in the Work-Up of GH Deficiency in the First Years of Life?

Pedicelli Stefania , Scire Giuseppe , Pampanini Valentina , Gubinelli Jessica , Spadoni Gian Luigi , Bitti Maria Luisa Manca , Cappa Marco , Boscherini Brunetto , Cianfarani Stefano

Background: Currently, the diagnosis of GH deficiency (GHD) in infants and young children is based on the assessment of GH serum levels either during hypoglycaemia or after pharmacological stimulation tests. However, GH cut-off values have not been standardized and provocative tests may be unsafe in this age range.Objective and hypotheses: Brain MRI may replace GH measurements in diagnosing GHD in infancy and young childhood.Method...
