Glucose Metabolism In Children with Prader-Willi Syndrome: The Effect Of Gh Therapy

Grugni Graziano , Fintini Danilo , Bocchini Sarah , Crino Antonino

Background: Numerous studies have shown that PWS patients demonstrate the preservation of insulin sensitivity despite severe obesity. Data about insulin secretion in PWS however, are still conflicting. Other reports showed that PWS subjects and simple obese controls had similar insulin levels and were both insulin resistant. These discrepancies could be due to the different clinical characteristics of the study groups, including age, weight excess levels and the presence/absen...

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...

Metabolic Alteration in Patients Affected by PseudoHypoParathyroidismo 1a (PHP1a): A Preliminary Data

Fintini Danilo , Ubertini Graziamaria , Scire Giuseppe , Covertino Alessio , Bocchini Sarah , Deodati Annalisa , Cappa Marco

Pseudohypoparathyroidism (PHP) is a rare disease characterized by hormone resistance due to defect of the α subunit of the stimulatory G protein (Gsα). Hypocalcemia due to parathyroid hormone (PTH) resistance is common. PHP1a determined by maternal LoF mutations in GNAS, presents severe obesity as early feature with increased risk of developing metabolic derangement during life. The aim of the study was to evaluate the metabolic alteration in a population of...

25-OH-Vitamin D Status in a Pediatric Population of Subjects Affected By Prader-Willi Syndrome Compared to Matched Obese Controls

Fintini Danilo , Pedicelli Stefania , Bocchini Sarah , Bizzarri Carla , Grugni Graziano , Cappa Marco , Crino Antonino

Background: Obesity is usually correlated with a higher prevalence of 25OH vitamin D (25OHD) deficiency. This might be due to either volumetric dilution of vitamin D in the large fat mass or its increased uptake by adipose tissue. To our knowledge, a systematic study on 25OHD levels in Prader-Willi syndrome (PWS), a genetic disorder associated with severe obesity, is not available.Objective and hypotheses: To analyze the 25OHD values in a population of p...

A Re-Evaluation of GH Secretion with Combined Test (GHRH+ARG/PD) in Children with Prader–Willi Syndrome

Fintini Danilo , Bocchini Sarah , Grugni Graziano , Brufani Claudia , Grossi Armando , Cappa Marco , Crino Antonino

Background: A reduced GH response to different stimulation tests have been documented in both children and adults with Prader–Willi syndrome (PWS), independently from obesity. Previous reports suggested the hypothesis of an age dependent derangement of the hypothalamus–pituitary axis occurring in PWS subjects.Objective and hypotheses: In this longitudinal study we re-evaluated the GH responsiveness to a combined test after long-term GH therapy ...

Bone Mineral Density in Prader-Willi Females During the Transition Phase

Grugni Graziano , Fintini Danilo , Mazzilli Giuliana , Bocchini Sarah , Sartorio Alessandro , Crino Antonino

Background: Adult subjects with Prader-Willi Syndrome (PWS) have low Bone Mineral Density (BMD) and are at risk of osteoporosis. Several observations suggest that peak bone mass is usually achieved by late adolescence, in the presence of adequate gonadal hormone concentrations. Consequently, the altered bone characteristics of PWS patients may be related to inadequate sex steroid levels during pubertal development.Aim: To investigate BMD in PWS females d...

Experience with Sleeve Gastrectomy in Adolescent Obese Subjects and in Prader-Willi Syndrome

Fintini Danilo , Bocchini Sarah , Caccamo Romina , Grugni Graziano , Cappa Marco , De Peppo Francesco , Crino Antonino

Background: Prader Willi syndrome (PWS) results from the loss of paternally imprinted genes on chromosome 15q11–15 and is characterized by neonatal hypotonia, short stature, hypogonadism, aggressive food-seeking behavior, hyperphagia, and obesity with difficult in losing weight only with nutritional approach.Objective and hypotheses: We report our experience on sleeve gastrectomy in PWS and obese subjects during 12 months of follow-...

Gender differences in Italian pediatric obese subjects

Inzaghi Elena , Tarissi Isabella , Deodati Annalisa , Fintini Danilo , Villani Alberto , Cianfarani Stefano

Background: Significant aspects of metabolic homeostasis are regulated differently in males and females and sex differences can influence diagnostic approach and therapeutic responses. The underlying mechanisms accounting for gender difference remain to be established and may involve genetic and hormonal factors.Aim: This study aimed at evaluating gender differences in anthropometric and metabolic parameters in a large c...

Refractory Hypercalcemia After Denosumab Treatment in Pediatric Age: A Case Report

Deodati Annalisa , Ubertini Graziamaria , Grossi Armando , Inzaghi Elena , Paone Laura , Maria Milano Giuseppe , Cappa Marco , Fintini Danilo

Background: Denosumab is a new class of antiresorptive medication and a fully human monoclonal antibody of the IgG2 immunoglobulin isotype to RANKL. In fact, it binds with high affinity and specificity to RANKL, mimicking the inhibitory effects of Osteoprotegerin, resulting in rapid suppression of bone resorption. Denosumab is commonly used also in pediatric age for treatment of osteoporosis, malignancies, and other benign bone lesions, such as fibrous dysplas...

Non-Alcoholic Fatty Liver Disease in Children/Adolescent Affected by Prader–WIlli Syndrome

Fintini Danilo , Inzaghi Elena , Bocchini Sarah , Grugni Graziano , Colajacomo Mauro , Brufani Claudia , Cappa Marco , Nobili Valerio , Cianfarani Stefano , Crino Antonino

Background: Prader–Willi syndrome (PWS) has a relative hypoinsulinemia and a lower insulin resistance than non-PWS subjects. Mostly on the basis of such higher insulin sensitivity, PWS subjects have been hypothesized to be at lower risk of non-alcoholic fatty liver disease (NAFLD).Objective and hypotheses: In this cross-sectional study, we analyzed the presence and the severity of NAFLD in a group of PWS children compared to matched pairs.<p cla...
