Persistently increased IGF-I levels and excellent auxological response despite low doses of recombinant growth hormone in a GH-deficient patient with a heterozygous variant of the growth hormone receptor (GHR) gene

Laura Nicolosi Maria , Cattoni Alessandro , Maitz Silvia , Marco Santo Di , Biondi Andrea , Molinari Silvia ,

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Serum anti-Müllerian hormone as a marker of ovarian reserve among childhood cancer survivors

Molinari Silvia , Parissone Francesca , Evasi Veronica , Marco Santo Di , Biondi Andrea , Cattoni Alessandro ,

Introduction: Female patients treated with alkylating agents in childhood are at risk for ovarian impairment. We aimed at describing the pattern of residual ovarian function in a cohort of hematological cancer survivors, assessing the relationship between the cumulative dose of alkylating agents administered (expressed as Cyclophosphamide Equivalent Dose - CED) and Anti-Müllerian Hormone (AMH) levels.Methods: Gonada...

Growth patterns in children with Mucopolysaccharidosis type I-Hurler after haematopoietic stem cell transplantation: comparison with untreated patients

Chiaraluce Sofia , Molinari Silvia , Di Marco Santo , Gasperini Serena , Biondi Andrea , Rovelli Attilio , Parini Rossella , Cattoni Alessandro ,

Background: Mucopolysaccharidosis I Hurler (MPS-IH is an inborn error of metabolism arising from the defective activity of alpha-L-iduronidase, an enzyme involved in the degradation of glycosaminoglycans (GAGs). As a result, the pathological lysosomal storage of GAGs in several tissues leads to multi-systemic complications, such as hepatosplenomegaly, progressive central nervous system deterioration, skeletal dysplasia and faltering growth, commonly resulting ...

A novel homozygous variant of the leptin receptor (LEPR) gene causing familiar early-onset severe obesity in two siblings

Molinari Silvia , Ceccarini Giovanni , Masera Nicoletta , Spano Alice , Maitz Silvia , Fossati Chiara , Lazzerotti Alessandra , Santini Ferruccio , Cattoni Alessandro ,

Introduction: The leptin-melanocortin pathway is a well-studied pivotal player of body weight regulation and energy homeostasis. Pathogenic mutations of the genes involved in this pathway may result in early-onset severe obesity (ESO).Case Report: We hereby report the case of a 14-year-old girl who was referred to our pediatric outpatient clinic for the evaluation of ESO. Her parents were non-obese first cousins born in Morocco. At the t...

Prospective longitudinal assessment of bone mineral density, circulating markers of bone turnover and changes in body composition in children and adolescents treated for acute lymphoblastic leukemia

Molinari Silvia , Laura Nicolosi Maria , Capitoli Giulia , Tondelli Daniele , Corbetta Sabrina , Vai Silvia , Radaelli Silvia , Biondi Andrea , Adriana Cristina Balduzzi , Sala Alessandra , Cattoni Alessandro

Background: Acute lymphoblastic leukemia (ALL) is the most frequently reported cancer in paediatrics. Reduced bone mineral density (BMD) and increased risk of fractures have been well-documented in this population, but long-term longitudinal trendlines of BMD and data about the impact of bone turnover markers are still scarce. Additionally, changes in body composition have to be furtherly analysed among childhood ALL survivors.St...

Pelvic ultrasound and pubertal attainment in girls with sexual precocity: the pivotal role of uterine volume in predicting the timing of menarche

Introduction: Among girls assessed for pubertal precocity, pelvic ultrasound (pUS) may represent a pivotal tool to predict the time expected to elapse between sonographic assessment and the onset of menarche (TUS-M). Accordingly, the present analysis is meant to define the statistical relationship between sonographic parameters and TUS-M, in order to identify the most reliable predictor of the timing of menarche.<st...
